Why Do Flamingos Stand on One Leg?

May 24th, 2017 Science

Flamingos are striking not only for their brilliant pink plumes, but for how they often stand on a single slender leg, even when asleep. Now scientists find that standing on one leg may counter-intuitively require less effort for flamingos than standing on two. It’s a finding that could help lead to more stable legged robots and better prosthetic legs.
The One-Legged Problem
One prior explanation for the mystery of why flamingos stand on one leg is that it conserved body heat, as doing

Death From Below: Invasive Lionfish Lurking in Deep Reefs, Sending Hungry Reinforcements to the Shallows

May 24th, 2017 Science

In the last few decades, scientists have come to appreciate the incredible creatures living on the reefs that lie just below conventional diving limits in what is called the mesophotic zone. These incredible biodiversity hotspots are home to more endemic species than shallower reefs, and conservationists are hopeful they may serve as refuges—pockets of relatively pristine habitat out of reach of anthropogenic stressors—where species under threat from pollution, overfishing, and even the effe

Why Are Whales So Dang Big? Science May Finally Have an Answer

Why Are Whales So Dang Big? Science May Finally Have an Answer

Baleen whales probably only grew colossal some 3 million years ago, and it was probably climate change that triggered the transformation. The post Why Are Whales So Dang Big? Science May Finally Have an Answer appeared first on WIRED.

Pope’s encyclical boosted his credibility on climate change, especially among liberals

May 23rd, 2017 Science

The Pope’s 2015 encyclical on climate change did not directly influence people’s beliefs about the seriousness of climate change or its effect on the poor, a study in Cognition has found. The papal message did, however, indirectly influence people’s beliefs about climate change by raising the Pope’s credibility on that issue, most strongly among liberals.

Alzheimer’s, Parkinson’s, and Huntington’s diseases share common crucial feature

May 23rd, 2017 Science

A study has found that abnormal proteins found in Alzheimer’s, Parkinson’s and Huntington’s diseases share a similar ability to cause damage when they invade brain cells. The finding suggests that an effective treatment for one neurodegenerative disease might work for other neurodegenerative diseases as well.

Study leads to breakthrough in better understanding acute myeloid leukemia

May 23rd, 2017 Science

A study led by the University of Birmingham has made a breakthrough in the understanding of how different genetic mutations cause acute myeloid leukemia.

Better science faster

May 23rd, 2017 Science

Scientists at UCSB’s NCEAS are transforming how complex marine data from the Ocean Health Index is synthesized, communicated and used for coastal management.

Special X-ray technique allows scientists to see 3-D deformations

May 23rd, 2017 Science

In a new study published last Friday in Science, researchers at Argonne used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects. These defects create imperfections in the lattice of atoms inside a grain that can give rise to interesting material properties and effects.

Biosynthetic secrets: How fungi make bioactive compounds

May 23rd, 2017 Science

Biological engineers at Utah State University have successfully decoded and reprogrammed the biosynthetic machinery that produces a variety of natural compounds found in fungi.

How X-rays helped to solve mystery of floating rocks

May 23rd, 2017 Science

Experiments at Berkeley Lab’s Advanced Light Source have helped scientists to solve a mystery of why some rocks can float for years in the ocean, traveling thousands of miles before sinking.

The high plains aquifer: Can we make it last?

May 23rd, 2017 Science

he heart of the United States is a highly productive agricultural region. This “breadbasket” underpins much of U.S. society, but it also relies almost entirely on a complex network of diminishing groundwater resources. In a short and provocative article, for GSA Today, Susan Stover and Rex Buchanan ask a simple question: “How long can the High Plains aquifer last?”

VLA reveals new object near supermassive black hole in famous galaxy

May 23rd, 2017 Science

When astronomers took a new look at a famous galaxy with the upgraded Very Large Array, they were surprised by the appearance of a new, bright object that had not appeared in previous images.

NASA sees powerful storms with advancing monsoon in Bay of Bengal

Storms associated with the advancing monsoon in the Northern Indian Ocean’s Bay of Bengal were analyzed by NASA with the GPM or Global Precipitation Measurement mission core satellite.

Using a genetic signature to overcome chemotherapy-resistant lung cancer

May 23rd, 2017 Science

Patients with non-small cell lung cancer (NSCLC) often respond to standard chemotherapy, only to develop drug resistance later, and with fatal consequences. But what if doctors could identify those at greatest risk of relapse and provide a therapy to overcome or avoid it?

Recreational cocaine: Brain area involved in addiction activated earlier than thought

May 23rd, 2017 Science

Even among non-dependent cocaine users, cues associated with consumption of the drug lead to dopamine release in an area of the brain thought to promote compulsive use, according to researchers at McGill University.

South highest, Northeast lowest for child auto fatalities

May 23rd, 2017 Science

The number of motor vehicle fatalities involving children under age 15 varies widely by state, but occurrences are more common in the South, and are most often associated with improperly or unused restraints and crashes on rural roads, a new review of child-related auto fatalities shows.

Genetic mutation trade-offs lead to parallel evolution

May 23rd, 2017 Science

Researchers at the University of Illinois at Urbana-Champaign have shown how evolutionary dynamics proceed when selection acts on two traits governed by a trade-off. The results move the life sciences a step closer to understanding the full complexity of evolution at the cellular level.

How to prevent 3-D printing hacks? Install secret flaws and share the decoder ring

May 23rd, 2017 Science

Since the global supply chain for additive manufacturing (AM)– also called 3-D printing– requires companies to share CAD files within the organization or with outside parties via email or cloud, intellectual-property thieves and malefactors have many opportunities to filch a manufacturer’s design files to produce counterfeit parts. Researchers have discovered ways for manufacturers to turn the tables on thieves by deliberately embedding hidden flaws in CAD files to thwart intellectual property theft.
