The commander of the International Space Station, Daniel Burbank, shook hands Wednesday with Robonaut. It’s the first handshake ever between a human and a humanoid in space.

NASA’s Robonaut was launched aboard space shuttle Discovery last February. Crews have been testing it to see how it one day might help astronauts perform space station chores.

On Wednesday, ground controllers activated computer software that enabled the robot to extend its right hand, fingers outstretched. Burbank took the mechanical hand and pumped it up and down, as the robot’s fingers tightened around his hand.

“The first human-humanoid handshake in space,” Burbank proclaimed.

A cheer went up in the control room in Huntsville, Ala.

“For the record, it was a firm handshake,” Burbank radioed. “Quite an impressive robot.”

Robonaut – the first humanoid in space, built from the waist up – said via Twitter that it was an awesome experience, then followed up with some sign language.

“The handshake was definitely one of the highlights of the day, but I’m not done yet,” Robonaut said in a tweet. (A NASA spokeswoman actually files the tweets under the handle AstroRobonaut.)

“Did you catch that? I don’t have a voice, but I sent you a message — Hello world … in sign language!” Robonaut tweeted. “What a day! I passed my tests with flying colors!!!”

Dutch space station astronaut Andre Kuipers couldn’t resist a little robot humor.

“Now let’s hope he’s never heard of HAL9000, Skynet or Cylons,” Kuipers wrote in a tweet.

HAL was the conspiring computer in “2001: A Space Odyssey.” The people-hating artificial intelligence system Skynet is from the “Terminator” films, while Cylons are cyber-warriors from “Battleship Gallactica.”

Robonaut spends most of its time in hibernation aboard the space station. The astronauts bring the humanoid out every so often for testing; it was awakened in space last August and made its first motion in October. A future model could venture outside for spacewalks, saving its human companions time and keeping them safe.

Call it Conspiracy City. Call it Scandal City. Call it Leak City. These days the holy city has been in the news for anything but holy reasons.

“It is a total mess,” said one high-ranking Vatican official who spoke, like all others, on the condition of anonymity.

The Machiavellian maneuvering and machinations that have come to light in the Vatican recently are worthy of a novel about a sinister power struggle at a medieval court.

Senior church officials interviewed this month said almost daily embarrassments that have put the Vatican on the defensive could force Pope Benedict to act to clean up the image of its administration – at a time when the church faces a deeper crisis of authority and relevance in the wider world.

Some of those sources said the outcome of a power struggle inside the Holy See may even have a longer-term effect, on the choice of the man to succeed Benedict when he dies.

From leaked letters by an archbishop who was transferred after he blew the whistle on what he saw as a web of corruption and cronyism, to a leaked poison pen memo which puts a number of cardinals in a bad light, to new suspicions about its bank, Vatican spokesmen have had their work cut out responding.

The flurry of leaks has come at an embarrassing time – just before a usually joyful ceremony this week known as a consistory, when Benedict will admit more prelates into the College of Cardinals, the exclusive men’s club that will one day pick the next Roman Catholic leader from among their own ranks.
“This consistory will be taking place in an atmosphere that is certainly not very glorious or exalting,” said one bishop with direct knowledge of Vatican affairs.

The sources agreed that the leaks were part of an internal campaign – a sort of “mutiny of the monsignors” – against the pope’s right-hand man, Secretary of State Cardinal Tarcisio Bertone.

Bertone, 77, has a reputation as a heavy-handed administrator and power-broker whose style has alienated many in the Curia, the bureaucracy that runs the central administration of the 1.3 billion-strong Roman Catholic Church.

He came to the job, traditionally occupied by a career diplomat, in 2006 with no experience of working in the church’s diplomatic corps, which manages its international relations. Benedict chose him, rather, because he had worked under the future pontiff, then Cardinal Joseph Ratzinger, in the Vatican’s powerful doctrinal office.

“It’s all aimed at Bertone,” said a monsignor in a key Vatican department who sympathizes with the secretary of state and who sees the leakers as determined to oust him. “It’s very clear that they want to get rid of Bertone.”
Vatican sources say the rebels have the tacit backing of a former secretary of state, Cardinal Angelo Sodano, an influential power-broker in his own right and a veteran diplomat who served under the late Pope John Paul II for 15 years.

“The diplomatic wing feels that they are the rightful owners of the Vatican,” the monsignor who favors Bertone said.

Sodano and Bertone are not mutual admirers, to put it mildly. Neither has commented publicly on the reports.

Whistle-blowing Archbishop

The Vatican has been no stranger to controversy in recent years, when uproar over its handling of child sex abuse charges has hampered the church’s efforts to stem the erosion of congregations and priestly recruitment in the developed world.

But the latest image crisis could not be closer to home.

It began last month when an Italian television investigative show broadcast private letters to Bertone and the pope from Archbishop Carlo Maria Vigano, the former deputy governor of the Vatican City and currently the Vatican ambassador in Washington.

The letters, which the Vatican has confirmed are authentic, showed that Vigano was transferred after he exposed what he argued was a web of corruption, nepotism and cronyism linked to the awarding of contracts to contractors at inflated prices.

As deputy governor of the Vatican City for two years from 2009 to 2011, Vigano was the number two official in a department responsible for maintaining the tiny city-state’s gardens, buildings, streets, museums and other infrastructure, which are managed separately from the Italian capital which surrounds it.

In one letter, Vigano writes of a smear campaign against him by other Vatican officials who were upset that he had taken drastic steps to clean up the purchasing procedures and begged to stay in the job to finish what he had started.

Bertone responded by removing Vigano from his position three years before the end of his tenure and sending him to the United States, despite his strong resistance.

Other leaks center on the Vatican bank, just as it is trying to put behind it past scandals – including the collapse 30 years ago of Banco Ambrosiano, which entangled it in lurid allegations about money-laundering, freemasons, mafiosi and the mysterious death of Ambrosiano chairman Roberto Calvi – “God’s banker.”

Today, the Vatican bank, formally known at the Institute for Works of Religion (IOR), is aiming to comply fully with international norms and has applied for the Vatican’s inclusion on the European Commission’s approved “white list” of states that meet EU standards for total financial transparency.

Bertone was instrumental in putting the bank’s current executives in place and any lingering suspicion about it reflects badly on him. The Commission will decide in June and failure to make the list would be an embarrassment for Bertone.

Italian Pope?

Last week, an Italian newspaper that has published some of the leaks ran a bizarre internal Vatican memo that involved one cardinal complaining about another cardinal who spoke about a possible assassination attempt against the pope within 12 months and openly speculated on who the next pope should be.

Bertone’s detractors say he has packed the Curia with Italian friends. Some see an attempt to influence the election of the next pope and increase the chances that the papacy returns to Italy after two successive non-Italian popes who have broken what had been an Italian monopoly for over 450 years.

Seven of the 18 new “cardinal electors” — those aged under 80 eligible to elect a pope — at this Saturday’s consistory are Italian. Six of those work for Bertone in the Curia.

Bertone, as chief administrator, had a key role in advising the pope on the appointments, which raised eyebrows because of the high number of Italian bureaucrats among them.

“There is widespread malaise and delusion about Bertone inside the Curia. It is full of complaints,” said the bishop who has close knowledge of Vatican affairs.

“Bertone has had a very brash method of running the Vatican and putting his friends in high places. People could not take it any more and said ’enough’ and that is why I think these leaks are coming out now to make him look bad,” he said.

Pope “Isolated”

Leaked confidential cables sent to the State Department by the U.S. embassy to the Vatican depicted him as a “yes man” with no diplomatic experience or linguistic skills and the 2009 cable suggests that the pope is protected from bad news.

“There is also the question of who, if anyone, brings dissenting views to the pope’s attention,” read the cable, published by WikiLeaks.

The Vatican sources said some cardinals asked the pope to replace Bertone because of administrative lapses, including the failure to warn the pope that a renegade bishop re-admitted to the Church in 2009 was a well-known Holocaust denier.

But they said the pope, at 84 and increasingly showing the signs of his age, is not eager to break in a new right-hand man.

“It’s so complicated and the pope is so helpless,” said the monsignor.
The bishop said: “The pope is very isolated. He lives in his own world and some say the information he receives is filtered. He is interested in his books and his sermons but he is not very interested in government.”

E-volo Multicopter Click here to get a bigger view of this amazing image. Beate Kern

Last October, near Karlsruhe, Germany, Thomas Senkel completed the first manned flight of an electric multicopter, flying it 10 feet off the ground for 90 seconds. Senkel, a physicist and paraglider pilot who helped found the company E-volo to build the craft, invented it after seeing a YouTube video of a German hobbyist’s remote-controlled hexacopter in action.

Multicopters are more stable and easier to control than helicopters. They’re also potentially safer: The craft can land even after four of its 16 rotors, each of which has its own battery-powered motor, have failed. Multicopters could also be fitted with a parachute (which would be caught in the overhead rotor on a helicopter). E-volo says it will build a two-seat multicopter by the spring and begin selling the craft for recreational purposes next year.

U.S. troops who carry as much as 100 pounds of gear could soon get a robotic mule capable of shouldering their burdens in the toughest terrain. Such a robot recently showed how it can follow a person and navigate around trees and rocks while climbing a hill in its first outdoor test — but it might someday follow spoken commands like a huge, obedient dog.

The four-legged, headless “LS3″ robot evolved as the quieter, faster and tougher version of Boston Dynamics’ “BigDog” robot funded by the U.S. military’s DARPA research arm. Upcoming trials will test the robot’s ability to carry 400 pounds on a tough 20-mile trek without any refueling for 24 hours.

“If successful, this could provide real value to a squad while addressing the military’s concern for unburdening troops,” said Army Lt. Col. Joe Hitt, program manager for the Defense Advanced Research Projects Agency (DARPA). “LS3 seeks to have the responsiveness of a trained animal and the carrying capacity of a mule.”

Added “hearing” technology could even allow human squad members to issue spoken commands such as “stop,” “sit” or “come here.”

The LS3 robot also acts as a mobile charging station for troops to recharge batteries for their radios, tablets or laptops while on patrol. That makes a huge difference when today’s Marine platoon carries 30 to 50 radios on patrol in Afghanistan, compared with just two or three radios during the Vietnam War.

DARPA just released a video showing the robot standing up from a sitting position and following a person walking up a hill during its first outdoor test. If everything goes well, a full 18 months of tests starting this summer will end with the robot going out on field exercises with the Marines.

Such a walking robot would join robotic helicopters already flying test missions to resupply Marines in Afghanistan. Those helicopters still need trained human operators to control them remotely, but eventually they may become fully autonomous aircraft capable of flying on their own.

An “intensitygram” from the Helioseismic and Magnetic Imager on NASA’s Solar Dynamics Observatory shows the double-barreled sunspot active region 1416 pointing toward Earth.

As solar activity builds toward an expected peak in 2013, a double-barreled sunspot has been doubling in size over the past couple of days and now has the potential to shoot significant eruptions in our direction.

It’s not certain that active region 1416 will erupt with coronal mass ejections as violent as the blasts that were thrown off by the sun late last month. But it has developed a mixed “beta-gamma” magnetic field that packs enough energy to throw off medium-scale solar flares, SpaceWeather.com reports.

“Any such eruptions this weekend would be Earth-directed as the sunspot turns to face our planet,” SpaceWeather’s Tony Phillips wrote.

Medium-size M-class flares are generally associated with the kinds of solar storms that produce enhanced auroral lights, but not huge inconveniences on Earth. It’s the X-class flares you really have to watch out for: That level of solar storming could affect radio communications as well as satellites and electrical grids if the operators of those systems aren’t careful.

NASA and the National Oceanic and Atmospheric Administration have a wide array of space assets monitoring the sun, and for now all’s quiet on the solar front. NOAA’s Space Weather Prediction Center reported some problems tracking the Advanced Composition Explorer, a satellite that plays a key role in tracking solar storms, but those problems are expected to go away as ACE’s orientation with respect to the sun improves.

The heart-shaped coronal mass ejection can be seen at about the 10 o’clock position on this image from the Solar and Heliospheric Observatory.

The prediction center’s Facebook page reports that on Friday, the sun threw off a slow-moving coronal mass ejection, or CME — in the shape of a heart, no less. “A preliminary model run predicts this CME will arrive, appropriately enough, on Valentine’s Day,” NOAA reports. So if you’re out with your Valentine that night, particularly in Scandinavia or Canada, watch the skies. Even if the earth doesn’t move, the aurora might glow.

Meanwhile, the sunspot region that caused all the auroral fireworks last month, known as AR1402, has moved around the far side of the sun. Solar scientists will be interested to see how that region has changed when it comes back into view. We’re still a year out from the anticipated peak in the sun’s 11-year activity cycle, so there’ll be lots of sun-watching ahead. The best ways to keep track on a daily basis is to check in with NOAA’s space weather center and SpaceWeather.com.

 
The Russian achievement is likened to Americans winning the epic race to the moon in 1969

How the Russians did it: This illustration shows how Russian scientists were able to reach a body of water the size of Lake Ontario that had been hidden for 20 million years under Antarctic ice.

After more than two decades of drilling in Antarctica, Russian scientists have reached a gigantic freshwater lake hidden under miles of ice for some 20 million years – a pristine body of water that may hold life from the distant past and clues to the search for life on other planets.

Finally touching the surface of Lake Vostok, the largest of nearly 400 subglacial lakes in Antarctica, is a major discovery avidly anticipated by scientists around the world.

Valery Lukin, the head of Russia’s Arctic and Antarctic Research Institute (AARI) who oversaw the mission and announced its success, likened the endeavor to the epic race to the moon won by American scientists over the Soviets in 1969.

“I think it’s fair to compare this project to flying to the moon,” he said Wednesday.

The Russian team hit the lake Sunday at the depth of 12,366 feet about 800 miles southeast of the South Pole in the central part of the continent.

Scientists hope the lake may allow a glimpse into microbial life forms that existed before the Ice Age and are not visible to the naked eye. Scientists believe that microbial life may exist in the dark depths of the lake despite its high pressure and constant cold – conditions similar to those expected to be found under the ice crust on Mars, Jupiter’s moon Europa and Saturn’s moon Enceladus.

“In the simplest sense, it can transform the way we think about life,” NASA’s chief scientist Waleed Abdalati told The Associated Press in a email.

American and British teams are drilling to reach their own subglacial Antarctic lakes, but Columbia University glaciologist Robin Bell said those lakes are smaller and younger than Vostok, which is the big scientific prize.

Russian researchers at the Vostok station in Antarctica pose for a celebrator picture on Monday after reaching subglacial Lake Vostok. The sign reads “05.02.12, Vostok station, boreshaft 5gr, lake at depth 3769.3 metres.”

“It’s like exploring another planet, except this one is ours,” she said.

Lake Vostok is 160 miles long and 30 miles across at its widest point, similar in area to Lake Ontario. It’s kept from freezing into a solid block by the mammoth crust of ice across it that acts like a blanket, keeping in heat generated by geothermal energy underneath.

The technological challenges of drilling through the ice crust in the world’s coldest environment have made the project unique.

Temperatures on the Vostok Station on the surface above have registered the coldest ever recorded on Earth, reaching minus 128 degrees Fahrenheit, and conditions were made even tougher by its high elevation, more than 11,000 feet above sea level, resulting in thin oxygen.

The effort, however, has drawn strong fears that 66 tons of lubricants and antifreeze used in the drilling may contaminate the pristine lake. Bell said the Russian team was doing its best “to try really hard to do it right” and avoid contamination, but some others were nervous.

University of Colorado geological sciences professor James White was among those who urged caution about drilling into subglacial lakes.

“Lake Vostok is the crown jewel of lakes there,” White said by telephone. “These are the last frontiers on the planet we are exploring, we really ought to be very careful.”

Lukin said Russia had waited for several years for international approval of its drilling technology before proceeding to reach the lake. He said about 50 cubic feet of kerosene and freon poured up to the surface tanks from the boreshaft, proof that the lake water streamed up from underneath, froze and then blocked the hole, sealing off the chance that any toxic chemicals could contaminate.

Russian scientists will later remove the frozen sample for analysis in December when the next Antarctic summer season comes. They reached the lake just before they had to leave at the end of the Antarctic summer, as plunging temperatures halted air links.

Some scientists hope that studies of Lake Vostok and other subglacial lakes will advance knowledge of Earth’s own climate and help predict its changes.

“It is an important milestone that has been completed and a major achievement for the Russians because they’ve been working on this for years,” said Professor Martin Siegert, a leading scientist with the British Antarctic Survey, which is trying to reach another Antarctic subglacial lake, Lake Ellsworth.

“The Russian team share our mission to understand subglacial lake environments and we look forward to developing collaborations with their scientists and also those from the U.S. and other nations, as we all embark on a quest to comprehend these pristine, extreme environments,” he said in an email.

Americans scientists are drilling at Lake Whillans, west of the South Pole.

In the future, Russian researchers plan to explore the lake using an underwater robot equipped with video cameras that would collect water samples and sediments from the bottom of the lake, a project still awaiting the approval of the Antarctic Treaty organization.

The prospect of lakes hidden under Antarctic ice was first put forward by Russian scientist and anarchist revolutionary, Prince Pyotr Kropotkin, at the end of the 19th century. Russian geographer Andrei Kapitsa noted the likely location of the lake and named it following Soviet Antarctic missions in the 1950s and 1960s, but it wasn’t until 1994 that its existence was proven by Russian and British scientists.

The drilling in the area began in 1989 and dragged on slowly due to funding shortages, equipment breakdowns, environmental concerns and severe cold.

The lake’s pristine water may make entrepreneurs sweat just thinking of its commercial potential, but Lukin shot that idea right down.

He said his team had no intention of selling any Vostok water samples but would eventually share the results of their work with scientists from other nations.

Neuroscience breakthroughs could be harnessed by military and law enforcers, says Royal Society report

Soldiers could have their minds plugged directly into weapons systems, undergo brain scans during recruitment and take courses of neural stimulation to boost their learning, if the armed forces embrace the latest developments in neuroscience to hone the performance of their troops.

These scenarios are described in a report into the military and law enforcement uses of neuroscience, published on Tuesday, which also highlights a raft of legal and ethical concerns that innovations in the field may bring.

The report by the Royal Society, the UK’s national academy of science, says that while the rapid advance of neuroscience is expected to benefit society and improve treatments for brain disease and mental illness, it also has substantial security applications that should be carefully analysed.

The report’s authors also anticipate new designer drugs that boost performance, make captives more talkative and make enemy troops fall asleep.

“Neuroscience will have more of an impact in the future,” said Rod Flower, chair of the report’s working group.

“People can see a lot of possibilities, but so far very few have made their way through to actual use.

“All leaps forward start out this way. You have a groundswell of ideas and suddenly you get a step change.”

The authors argue that while hostile uses of neuroscience and related technologies are ever more likely, scientists remain almost oblivious to the dual uses of their research.

The report calls for a fresh effort to educate neuroscientists about such uses of the work early in their careers.

Some techniques used widely in neuroscience are on the brink of being adopted by the military to improve the training of soldiers, pilots and other personnel.

A growing body of research suggests that passing weak electrical signals through the skull, using transcranial direct current stimulation (tDCS), can improve people’s performance in some tasks.

One study cited by the report described how US neuroscientists employed tDCS to improve people’s ability to spot roadside bombs, snipers and other hidden threats in a virtual reality training programme used by US troops bound for the Middle East.

“Those who had tDCS learned to spot the targets much quicker,” said Vince Clark, a cognitive neuroscientist and lead author on the study at the University of New Mexico. “Their accuracy increased twice as fast as those who had minimal brain stimulation. I was shocked that the effect was so large.”

Clark, whose wider research on tDCS could lead to radical therapies for those with dementia, psychiatric disorders and learning difficulties, admits to a tension in knowing that neuroscience will be used by the military.

“As a scientist I dislike that someone might be hurt by my work. I want to reduce suffering, to make the world a better place, but there are people in the world with different intentions, and I don’t know how to deal with that.

“If I stop my work, the people who might be helped won’t be helped. Almost any technology has a defence application.”

Research with tDCS is in its infancy, but work so far suggests it might help people by boosting their attention and memory. According to the Royal Society report, when used with brain imaging systems, tDCS “may prove to be the much sought-after tool to enhance learning in a military context”.

One of the report’s most striking scenarios involves the use of devices called brain-machine interfaces (BMIs) to connect people’s brains directly to military technology, including drones and other weapons systems.

The work builds on research that has enabled people to control cursors and artificial limbs through BMIs that read their brain signals.

“Since the human brain can process images, such as targets, much faster than the subject is consciously aware of, a neurally interfaced weapons system could provide significant advantages over other system control methods in terms of speed and accuracy,” the report states.

The authors go on to stress the ethical and legal concerns that surround the use of BMIs by the military. Flower, a professor of pharmacology at the William Harvey Research Institute at Barts and the London hospital, said: “If you are controlling a drone and you shoot the wrong target or bomb a wedding party, who is responsible for that action? Is it you or the BMI?

“There’s a blurring of the line between individual responsibility and the functioning of the machine. Where do you stop and the machine begin?”

Another tool expected to enter military use is the EEG (electroencephalogram), which uses a hairnet of electrodes to record brainwaves through the skull. Used with a system called “neurofeedback”, people can learn to control their brainwaves and improve their skills.

According to the report, the technique has been shown to improve training in golfers and archers.

The US military research organisation, Darpa, has already used EEG to help spot targets in satellite images that were missed by the person screening them. The EEG traces revealed that the brain sometimes noticed targets but failed to make them conscious thoughts. Staff used the EEG traces to select a group of images for closer inspection and improved their target detection threefold, the report notes.

Work on brain connectivity has already raised the prospect of using scans to select fast learners during recruitment drives.

Research last year by Scott Grafton at the University of California, Santa Barbara, drew on functional magnetic resonance imaging (fMRI) scans to measure the flexibility of brain networks. They found that a person’s flexibility helped predict how quickly they would learn a new task.

Other studies suggest neuroscience could help distinguish risk-takers from more conservative decision-makers, and so help with assessments of whether they are better suited to peacekeeping missions or special forces, the report states.

“Informal assessment occurs routinely throughout the military community. The issue is whether adopting more formal techniques based on the results of research in neuroeconomics, neuropsychology and other neuroscience disciplines confers an advantage in decision-making.”

Pyramid of the Sun, Teotihuacan.Photo: David Hamill – Flickr, CC

Archaeologists discovered a series of deposits in the interior of the Pyramid of the Sun at Teotihuacan in Mexico. The team of researchers announced their findings after exploring the 65-metre high pyramid from 2008 to 2011.

Using the 116 metre long tunnel excavated in the 1930s by archaeologist Eduardo Noguera, the Pyramid of the Sun Project, directed by Alejandro Sarabia, stratigraphically excavated 59 trenches and created 3 short tunnels in order to reach the natural rock level and verify the presence of burials and offerings.

“We knew that if the builders of Teotihuacan placed something inside the monument it would have been done at the base level, so we made a vertical shaft at the end of the tunnel and a short horizontal tunnel to reach the centre of the pyramid, since the original tunnel was cut approximately 6 metres to the west of the centre of the monument”, commented team member Perez Cortes.

A tunnel into the heart of the pyramid

Over the course of the exploration three architectural structures were discovered, constructed prior to the current Pyramid of the Sun. Seven human burials, including children, were also recorded as having been buried before the construction of the building. In addition, two votive deposits were recovered.

One of the votive offerings was discovered inside the original foundation material, so it is certain it was deposited as part of a consecration ceremony of the structure, probably at the beginning of its construction more than 1900 years ago.

The deposit, which contained an outstanding greenstone mask was part of several layers of artefacts.

A considerable number of obsidian artefacts including projectile heads and small knives were recovered, an anthropomorphic eccentric artefact and three anthropomorphic figurines with shell and pyrite eyes.

Among the three greenstone sculptures found, the mask carved from a single stone is, according to studies conducted by Dr. Jose Luis Ruvalcaba, from the National University Physics Institute (IF UNAM), “the only greenstone mask discovered in the ritual context of Teotihuacan.”

A man in Dorset has been left mystified after tiny blue spheres fell from the sky into his garden.

Steve Hornsby from Bournemouth said the 3cm diameter balls came raining down late on Thursday afternoon during a hail storm.

He found about a dozen of the balls in his garden. He said: “[They’re] difficult to pick up, I had to get a spoon and flick them into a jam jar.”

The Met Office said the jelly-like substance was “not meteorological”.

Mr Hornsby, a former aircraft engineer, said: “The sky went a really dark yellow colour.

“As I walked outside to go to the garage there was an instant hail storm for a few seconds and I thought, ’what’s that in the grass’?”

’No smell’

Walking around his garden he found many more blue spheres were scattered across the grass.

He said: “The have an exterior shell with a softer inner but have no smell, aren’t sticky and do not melt.”

Mr Hornsby said he was keeping the balls in his fridge while he tried to find out what they were.

Josie Pegg, an applied science research assistant at Bournemouth University, speculated that the apparently strange phenomena might be “marine invertebrate eggs”.

“These have been implicated in previous ’strange goo’ incidents,” she said. “I’d have thought it’s a little early for spawning but I suppose we’ve had a very mild winter.

“The transmission of eggs on birds’ feet is well documented and I guess if a bird was caught out in a storm this could be the cause.”

The balls that landed in the 61-year-old’s vegetable patch have an unusual blue tinge.

The transparent, slippery spheres that rained down on Steve Hornsby’s garden are about the size of marbles.
