Electrical fault corrected, 'Big Bang' collider to restart soon

CERN engineers said on Tuesday they have resolved a problem that had delayed the relaunch after a two-year refit of the Large Hadron Collider particle smasher, which is probing the mysteries of the universe. The relaunch of the so-called 'Big Bang' machine had to be postponed last week because of the problem. These collisions, at almost the speed of light, create the chaotic conditions inside th

Solitair device aims to takes guesswork out of sun safety

By Matthew Stock Scientists in the UK have developed a new wearable device that monitors the correct amount of sun exposure for a person's skin type in order to stay healthy. The Solitair device consists of a tiny sensor to measure how much sunlight the user is exposed to, with the information synchronized to a smartphone app that offers real time recommendations on when it is time to seek out som

Dutch architects show off 3D house-building prowess

Dutch architects are using a giant 3D printer to construct a prototype house in a bid to pave the way to a sustainable, environmentally-friendly, future for construction. DUS Architects of Amsterdam began construction of the house in 2014 and the prototype walls can already be seen - and touched - on site by curious visitors. The house structure uses a plastic heavily based on plant oil that co-fo

U.S.-Russian crew reaches space station for year-long stay

By Irene Klotz CAPE CANAVERAL, Fla (Reuters) - A Russian Soyuz rocket blasted off from the Baikonur Cosmodrome in Kazakhstan on Friday, sending a U.S.-Russia crew to the International Space Station for a year-long flight, a NASA Television broadcast showed. Four Soviet-era cosmonauts lived on the now-defunct Mir space station for a year or longer, but the missions, which concluded in 1999, did n

Bionic ants could be tomorrow's factory workers

By Amy Pollock Robotic ants the size of a human hand that work together could be the future of factory production systems. The developers, German technology firm Festo, say it's not just the unusual anatomy of real-world ants that inspired the bionic version - the collective intelligence of an ant colony was also something they wanted to replicate. Festo says that in the future production systems

How Long Would It Take to Fall Through the Earth?

How long would it take to fall down a hole in the Earth and reach the other side of the planet? The solution to this problem depends on the strength of Earth's gravitational pull, which in turn is based on its mass.

Shocking Discovery: Egypt's 'Mona Lisa' May Be a Fake

The "Meidum Geese," as modern-day Egyptologists and art historians call it, was supposedly found in 1871 in a tomb located near the Meidum Pyramid, which was built by the pharaoh Snefru (reign 2610-2590 B.C). A man named Luigi Vassalli discovered and removed the painting, which is now located in the Egyptian Museum in Cairo. "Some scholars compared it, with due respect, to 'The Gioconda' (Mona L

Birds' Foldable Wings Could Inspire Nimble Drones

A drone that mimics the way birds fold and flap their wings could improve the design of future unmanned autonomous vehicles, and could even help the machines withstand midair collisions. Now, researchers at Stanford University have designed a 3D-printed hinge inspired by this wrist joint.

Blood Moon: Shortest Total Lunar Eclipse of the Century Rises Saturday

Only the speediest of skywatchers will have a chance to see the total lunar eclipse rising Saturday: NASA predicts that the total phase of the lunar eclipse will only last about 5 minutes, making it the shortest lunar eclipse of the century. Early-rising observers all over the United States should be able to see at least the partial phases of the April 4 lunar eclipse just before the sun rises,

NASA Chief: 1-Year Space Station Mission Advances NASA Journey to Mars (Op-Ed)

Charles Bolden is the NASA Administrator. Today, we launch an American astronaut and a Russian cosmonaut to live and work in space for an entire year — the longest continuous stretch an American astronaut will have been in space.

Guess Your Age? 3D Facial Scan Beats Doctor's Exam

The researchers also found that levels of several biological markers in people's blood are associated with the markers of aging that appear on people's faces. For instance, women with older-looking faces tend to have higher levels of "bad" cholesterol, the researchers found. "3D facial images can really tell your biological age," said the study's senior researcher Jing-Dong Han, a professor of c

Despite deforestation, the world is getting greener - scientists

By Alisa Tang BANGKOK (Thomson Reuters Foundation) - The world's vegetation has expanded, adding nearly 4 billion tonnes of carbon to plants above ground in the decade since 2003, thanks to tree-planting in China, forest regrowth in former Soviet states and more lush savannas due to higher rainfall. It is present in the atmosphere primarily as carbon dioxide (CO2) - the main climate-changing gas

Quantum Record! 3,000 Atoms Entangled in Bizarre State

Using a single particle of light, scientists have for the first time linked together thousands of atoms in a bizarre state known as quantum entanglement, where the behavior of the atoms would stay connected even if they were at opposite ends of the universe. The behavior of all the known particles can be explained using quantum physics. A key feature of quantum physics is that the world becomes

Environmental group seeks greater protection for USDA scientists

An environmental activist group has filed a legal petition with the U.S. Department of Agriculture seeking new rules that would enhance job protection for government scientists whose research questions the safety of farm chemicals. The action filed on Thursday by the Public Employees for Environmental Responsibility, an advocacy group for local, state and federal researchers, came less than a week

Grants help level the playing field for young moms in science

By Randi Belisomo (Reuters Health) - Thanks to a generous benefactor, young mothers doing laboratory research at the Massachusetts General Hospital in Boston can receive major grants to keep them from falling behind while they raise their children.

Scientist defends WHO group report linking herbicide to cancer

A World Health Organization group's controversial finding that the world's most popular herbicide "probably is carcinogenic to humans" was based on a thorough scientific review and is a key marker in ongoing evaluations of the product, the scientist who led the study said Thursday. There was sufficient evidence in animals, limited evidence in humans and strong supporting evidence showing DNA mut

More Infidelity Uncovered in King Richard III's Family Tree

The remains of Richard III may be locked away in a coffin to be reburied this week, but the 15th-century king's genome is still offering scientists a chance to unravel royal mysteries. "Having worked in the world of genetic genealogy for years, this is not at all surprising to me," said Turi King, a geneticist at the University of Leicester. In the general population, false paternities occur in

A Year in Space: The Science Behind the Epic Space Station Voyage

Science experiments conducted on the International Space Station during the orbiting outpost's first yearlong mission could help open the door to deep space for NASA. Officials hope that one-year stint on the space station by astronaut Scott Kelly and cosmonaut Mikhail Kornienko will provide them with valuable health data that may help when the space agency decides to send humans to Mars sometim

Electric fault delays relaunch of CERN collider after two-year refit

By Robert Evans GENEVA (Reuters) - Scientists at Europe's CERN research centre have had to postpone the imminent relaunch of their refitted 'Big Bang' machine, the Large Hadron Collider, because of a short-circuit in the wiring of one of the vital magnets. "Current indications suggest a delay of between a few days and several weeks," a statement from the world's leading particle physics research

Want an affordable earthquake warning system? Use animals, scientists say

By Kieran Guilbert LONDON (Thomson Reuters Foundation) - Wild animals can predict earthquakes several weeks before they strike, and motion-activated cameras that track their movements could be adopted in quake-prone countries as an affordable early warning system, scientists said on Tuesday. Scientists using a series of cameras in an Amazon region of Peru noticed changes in animal behaviour three

Obama, wowed by young scientists, announces new STEM pledges

WASHINGTON (AP) — The small Lego machine inside the White House whirred, and in a moment it was turning the pages of a story book. One page flipped, then another, ever faster as President Barack Obama marveled at its efficiency.

Will We Combat Global Warming, Despite Our Nature? (Op-Ed)

In a recent article (Human Nature May Seal the Planet's Warming Fate), I used the allegory of "Who Moved my Cheese?" to suggest that people's innate biases may in fact be an evolutionary adaption, one that thwarts the changes demanded by climate change. This in contrast to simpler life forms such as mice: They have seemingly lower cognitive abilities, yet adapt far easier and more willingly to cha

Marijuana Science: Why Today's Pot Packs a Bigger Punch

The marijuana that is available today may be much more potent than marijuana cultivated in the past, according to the results of new tests. The psychoactive component in the marijuana plant is the chemical THC, and the new tests showed that today's marijuana may contain 30 percent THC, Andy LaFrate, the author of the new report, said in a statement. By contrast, THC levels in marijuana 30 years ag

Kids Whose Ears Stick Out Are Cuter, Science Confirms

The findings show that "protruding ears catch the eye, but not necessarily the imagination in a negative way," said Dr. Ralph Litschel, the lead author of the study. For some kids in the study, "protruding ears may have added to their cuteness," said Litschel, an ear, nose and throat specialist and facial plastic surgeon at Cantonal Hospital St. Gallen in Switzerland.

From Rocket Science to Low Rider: Former Engineer Builds Adult Big Wheels

Now, a Big Wheel-style bike is available for adults, thanks to the work of a former aerospace engineer. As a kid, Matt Armbruster dreamed of being an astronaut. It may not seem quite as noble as building things that expand humanity's understanding of the universe, but Armbruster said the power of these trikes — which look like adult-size versions of the Marx Big Wheel for kids — is something to

Dude, why is my mushroom glowing? Scientists have the answer

By Will Dunham WASHINGTON (Reuters) - If you think you see a glowing mushroom, you might not be having a psychedelic hallucination. Some mushrooms indeed are bioluminescent, including one that sprouts among decaying leaves at the base of young palm trees in Brazilian coconut forests. Researchers said on Thursday that experiments in Brazil involving the big, yellow mushroom called "flor de coco,"

Mystery of the 'Vampire Crabs' Solved

The crabs come from the island of Java in Indonesia, according to the scientists who officially describe the species in a new report. People in the aquarium trade have known of the two crab species described in the report for at least a decade, said Peter Ng, a biology professor at the National University of Singapore and an author of the report.

Chris Borland Leaves NFL: The Science of Football and Brain Injury

The up-and-coming professional football player Chris Borland, of the San Francisco 49ers, is now leaving the sport out of concern that a career in football would increase his risk of brain disease. On Monday (March 16), Borland announced he was retiring from football after studying the link between football head injuries and degenerative brain disease, and discussing his decision with friends, fam

Most Evangelical Christians Say Science and Religion Can Coexist

"Although many politicians and the media at large portray evangelicals as distrustful of science, we found that this is more myth than reality," Elaine Howard Ecklund, a sociologist at Rice University who orchestrated the survey, said in a statement. Among evangelical Christians, about 48 percent said they see science and religion as complementary to one another, while 21 percent think science a

Aspirin's colon-cancer benefits backfire for some DNA types - study

By Sharon Begley NEW YORK (Reuters) - Although numerous studies have shown that regular use of aspirin or related drugs can reduce the risk of colorectal cancer by about 30 percent, scientists have found an important exception: The medicines can actually increase the risk in people with certain genetic variants, new research shows. The result, published on Tuesday, is yet another step on the road
