Shots fired from world's first 3D-printed gun

Published May 06, 2013

The world's first 3D-printed handgun has been successfully fired in Texas, according to its creator Defense Distributed.

All 16 parts of the controversial gun, called the Liberator, are made from a tough, heat-resistant plastic used in products such as musical instruments, kitchen appliances and vehicle bumper bars.

Fifteen of those are made with a 3D printer while one is a non-functional metal part which can be picked up by metal detectors, making it legal under U.S. law. The firing pin is also not made of plastic, though it is easily crafted from a metal nail.

The weapon is designed to fire standard handgun rounds and even features an interchangeable barrel so that it can handle different caliber rounds. The blueprint files are expected to be available online today for download.

Reuters

Three Ohio women rescued a decade after they vanished

By Kim Palmer

CLEVELAND
Tue May 7, 2013 9:45am EDT

(Reuters) - Three women who vanished separately as teenagers about a decade ago were found alive in a house in Cleveland with police arresting three brothers, including a school bus driver.

Authorities were alerted to the missing women's whereabouts on Monday evening by a frantic emergency call from one of them, Amanda Berry, moments after she was freed from the house by a neighbor who said he heard screaming and came to her aid.

"Help me! I'm Amanda Berry. ... I've been kidnapped and I've been missing for 10 years and I'm here. I'm free now," Berry, now 26, is heard telling a 911 operator in a recording of the call released by police and posted on the Internet.

Berry had last been seen leaving her job at a fast-food restaurant the day before her 17th birthday in April 2003. The two women found with her were identified by authorities as Gina DeJesus, 23, who vanished in 2004 aged 14 while walking home from school, and Michelle Knight, who was reported to have been 18 or 19 when she went missing in 2002.

A physician at MetroHealth Medical Center, where the three women were taken for evaluation, said all were safe and appeared to be in "fair condition."

"This isn't the ending we usually have to these stories," Dr. Gerald Maloney said. "We're very happy for them."

The three were released from the medical center on Tuesday morning, according to a hospital spokeswoman. She provided no other details.

The house is close to where each woman was last seen, and police believe they were in the home for the entire time they were missing. The circumstances of their apparent abductions and captivity remained murky, but officials said further details would be disclosed at a news conference early on Tuesday.

During her 911 call, Berry gave the name of a man she said had abducted her. She said he had left the house and urged police to come quickly before he returned. She indicated that she knew her disappearance had been widely reported in the media.

The neighbor who came to her assistance, Charles Ramsey, said that after he helped Berry force open the door, she emerged from the dwelling "with a little girl," but authorities said nothing about the presence of any children in the house.

All three women were from the west-side section of Cleveland where they ultimately resurfaced.

There was no word on the fate of a fourth missing girl, Ashley Summers, who disappeared from the same vicinity in July of 2007 aged 14 and who police investigated as possibly linked to the Berry and DeJesus cases, according to the Charley Project website, which documents more than 9,000 missing-persons cases.

MOTHER KEPT SEARCHING

The disappearance of Knight did not attract the local media attention of the suspected abductions of Berry and DeJesus. Her grandmother, Deborah Knight, told the Cleveland Plain Dealer newspaper that some family members had concluded, based in part on suggestions by police and social workers at the time, that she had run away.

But her mother Barbara Knight, who now lives in Florida, told the newspaper she never believed her daughter would have vanished without a trace on her own and that she kept searching long after police gave up looking for her.

The suspects, aged 50, 52 and 54, were arrested based on information given to investigators by the three women after their rescue, according to Deputy Cleveland Police Chief Ed Tomba. One of the men was identified as Ariel Castro, 52, who has worked as a bus driver for Cleveland public schools and whose uncle said he owned the house in question.

A woman who lived on the same street but asked not to be identified said Castro lived alone in the house. She said he drove her two daughters to school and would drop them off in front of her house.

"I'm totally in shock. He seems like a normal guy. He was a gentleman. We all call him Mr. C," she said.

A man who helped to look for DeJesus, Pastor Angel Arroyo, said he and her family members had handed out flyers in the neighborhood where she was found.

"We didn't search hard enough. She was right under our nose the whole time," Arroyo said.

A mood of jubilation pervaded the city as word spread that the women had been found alive, especially in the blue-collar, heavily Latino neighborhood where dozens of residents clustered near the house from which they were rescued.

A Puerto Rican flag hung from the porch of the modest, two-story dwelling, cordoned off with crime-scene tape. Cheers from the crowd erupted periodically as police cars entered the area.

City Councilwoman Dona Brady, a friend of the Berry family, told Reuters that Berry's grief-stricken mother had not survived to see her daughter rescued. "She literally died of a broken heart," Brady said, adding that the mother died aged 47.

A cousin of DeJesus, Sheila Figaro, told CNN that the girl's mother, Nancy, "never gave up faith knowing that her daughter would one day be found." "What a phenomenal Mother's Day gift she gets this Mother's Day," she said.

The discovery of the three women was reminiscent of the case of Jaycee Dugard, who was snatched from her northern California home at age 11 by a convicted sex offender, Phillip Garrido, and kept in captivity for 18 years before being rescued in 2009.

During that time she was repeatedly raped by her abductor and gave birth to two girls fathered by him.

Man with runny nose had leaking brain

An Arizona man who thought he had a chronic runny nose has been told by doctors he actually had a leaking brain.

By Chris Irvine
11:08AM BST 07 May 2013

Joe Nagy initially noticed a clear liquid dribbling out of his nose "like tears out of your eyes" once or twice a week, but it soon became a problem week-round.

When he started to take allergy medicine, the runny nose failed to clear up.

After 18 months, he eventually sought the opinion of a specialist after an embarrassing incident in which a dollop splashed on to blueprints for model aeroplanes.

Rather than a runny nose, doctors found that the membrane surrounding Mr Nagy's brain had a hole in it and his brain fluid was leaking out.

Peter Nakaji, a neurosurgeon at Barrow Neurological Institute, told My Fox Phoenix that the brain produces up to 12 ounces of brain fluid a day.

"You don't really think about it, but our brains are really just above our noses all of the time," he said.

"This is one of the more common conditions to be missed for a long time ... because so many people have runny noses."

Dr Nakaji was able to find the leak and was able to fix it with routine surgery, although it was complicated by Mr Nagy suffering from a bout of near-deadly meningitis.

Mr Nagy however is now recovering.

Plants 'Talk' to Plants to Help Them Grow

May 7, 2013 — Having a neighborly chat improves seed germination, finds research in BioMed Central's open access journal BMC Ecology. Even when other known means of communication, such as contact, chemical and light-mediated signals, are blocked, chilli seeds grow better when grown with basil plants. This suggests that plants are talking via nanomechanical vibrations.

Monica Gagliano and Michael Renton from the University of Western Australia attempted to grow chilli seeds (Capsicum annuum) in the presence or absence of other chilli plants, or basil (Ocimum basilicum). In the absence of a neighboring plant, germination rates were very low, but when the plants were able to openly communicate with the seeds more seedlings grew.

However when the seeds were separated from the basil plants with black plastic, so that they could not be influenced by either light or chemical signals, they germinated as though they could still communicate with the basil. A partial response was seen for fully grown chilli plants blocked from known communication with the seeds.

Dr Gagliano explained, "Our results show that plants are able to positively influence growth of seeds by some as yet unknown mechanism. Bad neighbors, such as fennel, prevent chilli seed germination in the same way. We believe that the answer may involve acoustic signals generated using nanomechanical oscillations from inside the cell which allow rapid communication between nearby plants."

The Star Trek Fan Art That IBM Scientists Created Out of Atoms

By Graeme McMillan
05.07.13
6:30 AM

What happens if you give scientists who grew up loving classic science-fiction television the technology to re-assemble individual atoms into shapes of their choosing? The answer is, of course, the greatest Star Trek fan art imaginable: images literally built out of individual atoms.

The images are the work of IBM scientists who created the unique artwork with a two-ton machine called the Scanning Tunneling Microscope that moves single atoms across a tiny piece of copper. The machine was invented by Gerd Binnig and Heinrich Rohrer in 1981 as a way of “seeing” the atom, and re-purposed by another IBM scientist, Don Eigler, in 1989 when he discovered that the microscope could also move atoms before it took pictures of them.

“Think of it as a robot that has an arm, with a needle at the end that is sharp to the size of an atom,” explained Andreas Heinrich, Principal Investigation for IBM Research. “With that sharp needle, we can move with extremely fine precision; we can move the point say, one atom to the left. We use that needle to move atoms or molecules that are sitting on top of a surface, and with this kind of precision, we can say ‘Okay, I want to take one molecule or atom and I want to move it three atoms to the left.’”

Each point on these images represents one single atom on the copper plate. (We don’t see the atoms that make up the copper plate itself because, according to Heinrich, the copper’s surface is so smooth that it appears perfectly flat to the microscope.) Of course, working on such a small scale — these images are magnified more than 100 million times from the originals — has its drawbacks.

Although an image can be created in as little as five minutes once the scientists start moving the atoms, there’s a complicated process ahead of time to map out just where the atoms need to be in order to make the image they want. “The atoms want to sit in a certain location,” Heinrich said. “We can’t move an atom half-an-atom to the left, we can only move it one whole atom to the left. That leaves a distinct set of possible points that we can use. There’s a very limited set of ‘pixels’ that we have to work with.”

That means a lot of planning ahead of time to create an atom map for each image, which is used as a guide for the finished product. “We start with the atoms in random locations, and we use the frame that’s been located and move one to the right location, move another to the right location and check, did we do the right thing, before we move on and move as many as we need to make the final image,” Heinrich said. Surprisingly, each atom is moved by hand, instead of through an automated process. “The moving part is really, really fun,” Heinrich laughed. “It’s not as tedious as it sounds.”

And what better use for this technology than to create images in celebration of one of the greatest sci-fi franchises of all time? The two came together naturally, according to IBM Research’s Ari Entin. “Star Trek fans tend to have an appreciation of science and technology,” he said. “Some of the earliest Star Trek movies and TV shows inspired a whole new generation of scientists, so we thought that this would be an appropriate fit.”

For Heinrich, there’s an appropriate symmetry to the pairing. “Their claim to fame is that they’re dealing with the final frontier, with space. What we’re doing is dealing with the final frontier of engineering. The finest thing you’ll ever deal with in engineering is atoms. There’s nothing beyond that point,” he said. “So, we’re dealing with the final frontier of small, and they’re dealing with the final frontier of large.”

Despite the scale of the images, IBM Research is thinking bigger when it comes to using its atomic art. In addition to the Star Trek images, Heinrich’s team have created an entire movie made up of frames created of atoms. Called A Boy and His Atom: The World’s Smallest Movie, the minute-long short has been named “the world’s smallest movie” by the Guinness World Records committee and racked up almost 2.5 million views on YouTube.

“The best thing that we can create is an interest in the general public, in kids, for science,” Heinrich says. “That’s what I want to achieve with this. I’ll actually be at the EPCOT Center in Disney World in Florida this week, giving live presentations of the film and broadcasting them to schools across the country, to drive home the message that we want to get kids interested in science.”

Scotty would be proud.

Sunlight could help to lower blood pressure

Spending 20 minutes in the sun could help to lower your risk of heart disease, scientists have claimed.

By Richard Gray, Science Correspondent
7:00AM BST 08 May 2013

Researchers at the University of Edinburgh found that exposure to ultraviolet light lowered the blood pressure of volunteers.

Scientists say the findings may lead them to reconsider current advice for sun exposure.

High blood pressure is one of the main risk factors in heart disease and stroke. Around a third of the population suffer from high blood pressure.

The scientists believe that UV rays in sunlight cause nitrogen stored in the body to be released into the blood stream, relaxing blood vessels and lowering blood pressure.

Dr Richard Weller, a senior lecturer in dermatology at the University of Edinburgh who led the research, cautioned that more work needs to be done before they were able to offer advice to patients about using sunlight as a treatment for high blood pressure.

He said: "We now plan to look at the relative risks of heart disease and skin cancer in people who have received different amounts of sun exposure.

“If this confirms that sunlight reduces the death rate from all causes, we will need to reconsider our advice on sun exposure.

"We suspect that the benefits to heart health of sunlight will outweigh the risk of skin cancer.”

The researchers, who are presenting their findings at the International Investigative Dermatology Conference in Edinburgh, studied the blood pressure of 24 volunteers.

They were asked to spend 20 minutes under a UV tanning lamp, which allowed the dose of light to be controlled.

The scientists found while after receiving UV light, the volunteers’ blood pressure dropped and remained lower than before exposure for up to an hour.

When the volunteers were exposed to heat but no UV light from the tanning lamps, their blood pressure also dropped during exposure but then quickly increased back to previous levels.

Laboratory tests also showed that skin cells exposed to UV light released nitric oxide, a nitrogen based chemical that is known to cause blood vessels to relax.

UV from sunlight is known to have a number of benefits by helping the body produce vitamin D, but it is also the main cause of damage that causes skin cancer.

Nina Goad, from the British Association of Dermatologists, warned that the latest findings were still in their early stages as the study had been very small.

She said: "Research in this area is still very much in its infancy.

“Emerging evidence about possible health benefits of sunlight do not invalidate the indisputable weight of evidence showing the link between excess UV exposure and skin cancer, which is the UK's most common form of cancer.”

Dr Clare Walton, research communications officer at the Stroke Association, added: “We know that moderate exposure to sunshine can have multiple health benefits, however this is the first time that the link between sunshine and stroke risk has been explored.

The results show that sun exposure can reduce blood pressure, which is the biggest risk factor for stroke. It will be interesting to see how long these positive effects last and whether sunshine can play a role in reducing stroke risk.

“However, it’s an extremely small study and a lot more research is needed. It’s also important to remember that exposure to excess sunshine can be harmful to our health and everyone should take the necessary precautions this summer.”

U.S., Russia seek new Syria peace talks; rebels skeptical

By Arshad Mohammed and Erika Solomon

MOSCOW/BEIRUT
Wed May 8, 2013 7:46am EDT

(Reuters) - Russia and the United States agreed to seek new peace talks with both sides to end Syria's civil war, but opposition leaders were skeptical on Wednesday of an initiative they fear might let President Bashar al-Assad to cling to power.

Visiting Moscow after Israel bombed targets near Damascus and as President Barack Obama faces renewed calls to arm the rebels, U.S. Secretary of State John Kerry said Russia had agreed to try to arrange a conference as early as this month.

An East-West disagreement that has seen some of the frostiest exchanges between Washington and Moscow since the Cold War has deadlocked U.N. efforts to settle the Syrian conflict for two years, so any rapprochement could bring an international common front closer than it has been for many months.

Israeli air strikes, reports of the use of chemical weapons and the increasing prominence of al Qaeda-linked militants among the rebels have all added to international urgency for an end to a war that has killed more than 70,000 people.

But with Syria's factional and sectarian hatreds more entrenched than ever, it is far from clear the warring parties are ready to negotiate with each other. Most opposition figures have ruled out talks unless Assad and his inner circle are excluded from any future transitional government.

"No official position has been decided but I believe the opposition would find it impossible to hold talks over a government that still had Assad at its head," said Samir Nashar, a member of the opposition's umbrella National Coalition body.

"Before making any decisions we need to know what Assad's role would be. That point has been left vague, we believe intentionally so, in order to try to drag the opposition into talks before a decision on that is made."

In the past, the United States has backed opposition demands that Assad be excluded from any future government, while Russia has said that must be for Syrians to decide, a formula the opposition believes could be used to keep Assad in power.

Opposition members said they were concerned by comments from Kerry in Moscow, echoing Russia, that the decision on who takes part in a transitional government should be left to Syrians.

"Syrians are worried that the United States is advancing its own interests with Russia using the blood and suffering of the Syrian people," said National Coalition member Ahmed Ramadan.

"We are in touch with the U.S. side and need to be assured that there is no change in its position on Assad."

Inside the country, where rebel groups are numerous and have disparate views, a military commander in the north, Abdeljabbar al-Oqaidi, told Reuters he would want to know details of the U.S.-Russian plan before taking a view. "But," he added, "if the regime were present, I do not believe we would want to attend."

There was no immediate response from the Syrian government, which has offered reforms but dismisses those fighting it as terrorists and puppets of outside powers - the West, Turkey and Arab states opposed to Assad's ally Iran. Speaking before the announcement in Moscow, Assad sounded his usual defiant tone.

"The recent Israeli aggressions expose the extent of the complicity between the Israeli occupier, regional countries and the West in promoting the current events in Syria," he was quoted as saying by a Lebanese televisions station.

"The Syrian people and their heroic army ... are capable of confronting this Israeli adventure, which represents one of the faces of terrorism that is targeting Syria every day."

COMMON INTERESTS

Alarmed at the prospect of the conflict spilling across a volatile region central to global energy supplies and transit routes, the major powers have, as Kerry told Putin on Tuesday, "very significant common interests" in pushing for a settlement.

"The alternative," Kerry later told a joint news conference with Russian Foreign Minister Sergei Lavrov, "is that Syria heads closer to an abyss, if not over the abyss and into chaos."

Both sides fear a failed state in Syria could provide a base for hostile militants willing to strike around the world.

Last June, at a conference in Geneva, Washington and Moscow agreed on the need for a transitional government in Syria but left open the question of whether Assad would be excluded. Diplomacy has foundered since then, and the mediator of the Geneva conference, former U.N. Secretary General Kofi Annan, quit in despair, saying differences among powers were too wide.

Rejecting a characterization of Moscow as the protector of Assad, to whom it still provides arms, Lavrov said Russia was not concerned by the fate of "certain" individuals.

"The task now is to convince the government and all the opposition groups ... to sit at the negotiating table," he said.

Kerry said the conference should be held "as soon as is practical - possibly and hopefully by the end of the month". Neither he nor Lavrov said where it might take place.

Russia, backed by China, has vetoed three U.N. Security Council resolutions hostile to Assad. Alarmed at Western powers' use of a U.N. mandate to oust Muammar Gaddafi in Libya, Moscow and Beijing are wary of such interference in their own affairs.

ASSAD DEFIANT

Recent developments have focused minds on the risks of wider war in the Middle East.

The White House said last month that Assad's troops had probably used chemical weapons - which Obama has called a "red line" that would mandate a strong, if unspecified, response. The Syrian government and the rebels have each accused the other of using poison gas, a charge both sides deny.

Islamist fighters have pledged allegiance to al Qaeda, highlighting the risk to the West that a poorly managed change of leadership in Syria could bring hostile militants to power.

And Israeli air strikes in recent days - which Israeli officials said hit Iranian arms headed for Assad and Tehran's Lebanese allies Hezbollah - underlined the risk of escalation and cross-border conflict in the heart of the Middle East.

The violence has inflamed a confrontation between Sunni and Shi'ite Muslims in the Middle East, with Shi'ite Iran supporting Assad and Sunni powers like Saudi Arabia backing the rebels.

Tehran warned of unforeseeable consequences if Assad were toppled and said only a political settlement would avert a regional conflagration.

"God forbid, if there is any vacuum in Syria, these negative consequences will affect all countries," Foreign Minister Ali Akbar Salehi said in Jordan. "No one knows what will happen."

Wanted: Citizen Scientists to Hunt 'Space Warp' Galaxies

by Mike Wall, SPACE.com Senior Writer

Date: 08 May 2013
Time: 07:00 AM ET

Astronomers are calling for volunteers to help them search for "space warps," rare and distant galaxies that bend light around them like enormous lenses.

Citizen scientists participating in the Space Warps project, which launches Wednesday (May 8), could help shed light on the mysterious dark matter pervading the universe and aid research into a number of other cosmic phenomena, organizers said.

"Not only do space warps act like lenses, magnifying the distant galaxies behind them, but we can also use the light they distort to weigh them, helping us to figure out how much dark matter they contain and how it’s distributed," Phil Marshall, a physicist at Oxford University in England and one of Space Warps' leaders, said in a statement.

"Gravitational lenses help us to answer all kinds of questions about galaxies, including how many very-low-mass stars, such as brown dwarfs — which aren’t bright enough to detect directly in many observations — are lurking in distant galaxies," Marshall added.

The Space Warps project asks armchair astronomers to spot gravitational lenses in hundreds of thousands of deep-sky images. The human brain is more adept than computers at picking out patterns, and amateurs can do it about as well as professional astronomers can, organizers said.

Participants don't have to spend hours peering at their computers to make a meaningful contribution, Space Warps leaders said.

"Even if individual visitors only spend a few minutes glancing over 40 or so images each, that’s really helpful to our research — we only need a handful of people to spot something in an image for us to say that it’s worth investigating," Oxford's Aprajita Verma, another of Space Warps' principal investigators, said in a statement.

Intelligent Robots Will Overtake Humans by 2100, Experts Say

Are you prepared to meet your robot overlords?

The idea of superintelligent machines may sound like the plot of "The Terminator" or "The Matrix," but many experts say the idea isn't far-fetched. Some even think the singularity — the point at which artificial intelligence can match, and then overtake, human smarts — might happen in just 16 years.

But nearly every computer scientist will have a different prediction for when and how the singularity will happen.

Some believe in a utopian future, in which humans can transcend their physical limitations with the aid of machines. But others think humans will eventually relinquish most of their abilities and gradually become absorbed into artificial intelligence (AI)-based organisms, much like the energy making machinery in our own cells.

Singularity near?

In his book "The Singularity is Near: When Humans Transcend Biology" (Viking, 2005), futurist Ray Kurzweil predicted that computers will be as smart as humans by 2029, and that by 2045, "computers will be billions of times more powerful than unaided human intelligence," Kurzweil wrote in an email to LiveScience.
"My estimates have not changed, but the consensus view of AI scientists has been changing to be much closer to my view," Kurzweil wrote.

Bill Hibbard, a computer scientist at the University of Wisconsin-Madison, doesn't make quite as bold a prediction, but he's nevertheless confident AI will have human-level intelligence some time in the 21st century.

"Even if my most pessimistic guess is true, it means it's going to happen during the lifetime of people who are already born," Hibbard said.

Infinite abilities

Once the singularity occurs, people won't necessarily die (they can simply upgrade with cybernetic parts), and they could do just about anything they wanted to — provided it were physically possible and didn't require too much energy, Hibbard said.

The past two singularities — the Agricultural and Industrial revolutions — led to a doubling in economic productivity every 1,000 and 15 years, respectively, said Robin Hanson, an economist at George Mason University in Washington, D.C., who is writing a book about the future singularity. But once machines become as smart as men, the economy will double every week or month.

This rapid pace of productivity would be possible because the main "actors" in the economy, namely people, could simply be replicated for whatever it costs to copy an intelligent-machine software into another computer.

Earth's destruction?

That productivity spike may not be a good thing. For one, robots could probably survive apocalyptic scenarios that would wipe out humans.
"A society
or economy made primarily of robots will not fear destroying nature in the same way that we should fear destroying nature," Hanson said.

Human devolution?

Some scientists think we are already in the midst of the singularity.
Humans have already relinquished many intelligent tasks, such as the ability to write, navigate, memorize facts or do calculations, Joan Slonczewski, a microbiologist at Kenyon college and the author of a science-fiction book called "The Highest Frontier," (Tor Books, 2011). Since Gutenberg invented the printing press, humans have continuously redefined intelligence and transferred those tasks to machines. Now, even tasks considered at the core of humanity, such as caring for the elderly or the sick, are being outsourced to empathetic robots, she said.

"The question is, could we evolve ourselves out of existence, being gradually replaced by the machines?" Slonczewski said. "I think that's an open question."
