U.S. panel adds rare brain disease to newborn screening list, after push from families
A long-simmering scientific battle took on new life this week, as experts clashed in a San Francisco courtroom over whether the U.S. Environmental Protection Agency (EPA) should ban fluoridation of drinking water to protect fetuses and children from the risk of neurodevelopmental problems.

Billion-dollar NASA mission will provide unprecedented view of ocean life
Give future parents in our shoes a choice, before it’s too late. That’s what several parents of babies born with a fatal genetic brain disorder called Krabbe disease told a federal advisory panel on newborn screening this week. One mother from Virginia, Kelly Danoy, said her 2-year-old daughter Sofia “suffers needlessly because she was born in the wrong state.”
James Webb telescope provides new clues into the nature of our Milky Way galaxy
It isn’t easy seeing green. The ocean’s mix of plankton, algae, and bacteria absorbs vast amounts of carbon dioxide while producing 50% of Earth’s oxygen. But for decades, Earth-observing satellites could not tease apart the many species making up the green goop. That hampered attempts to study how the floating plants influence climate—and how global warming is affecting this...
Scientists see an ultra-fast movement on surface of HIV virus
The James Webb Space Telescope continues to astound astronomers. A recently released gallery of galaxies shows stunning details of 19 nearby spiral galaxies that are similar to our own Milky...

Plant groupings in drylands support ecosystem resilience
Seeing a glycoprotein on the envelope of the HIV virus snap open and shut in mere millionths of a second is giving investigators a new handle on the surface of the virus that could lead to broadly neutralizing antibodies for an AIDS vaccine. Being able to attach an antibody specifically to this little structure that would prevent it from popping open would be key.

New discoveries show early humans lived in the frigid north alongside Neanderthals
Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new article focused on the spatial patterns found in drylands offers important empirical evidence validating the models.
Lupus and Other Autoimmune Diseases Strike Far More Women Than Men. Now There’s a Clue Why
New discovery of human bones suggest that Homo sapiens were living side by side with Neanderthals in Northern Germany, 46,000 years ago. Another discovery of a stone-age ropemaking tools is shedding light on the inventive nature of these ancient...
Colin Murray Parkes obituary
WASHINGTON — Women are far more likely than men to get autoimmune diseases, when an out-of-whack immune system attacks their own bodies — and new research may finally explain why.
It’s all about how the body handles females’ extra X chromosome, Stanford University researchers reported Thursday — a finding that could lead to better ways to detect a long list...
Ice and fire: Antarctic volcano may hold clues to life on Mars
Psychiatrist whose insights into bereavement were shaped by events such as the Aberfan disaster, the Rwanda genocide and 9/11The much-quoted phrase “Grief is the price we pay for love” reached a global audience in 2001 when Queen Elizabeth II used it in her message of condolence to those affected by the 9/11 attacks in the US.But it was the psychiatrist Colin Murray Parkes, who has died aged...
French govt under fire for putting pesticide phase-out on hold
On Deception Island in Antarctica, steam rises from the beaches, and glaciers dot the black slopes of what is actually an active volcano—a rare clash of ice and fire that provides clues to scientists about what life could look like on Mars.
Extreme heat, wildfire smoke harm low-income and nonwhite communities the most, study finds
France's government was on the defensive on Friday after environmental campaigners and opposition politicians accused it of having scrapped a key green policy to appease protesting farmers.
Progress on chip-based spontaneous four-wave mixing quantum light sources
Extreme heat and wildfire smoke are independently harmful to the human body, but together their impact on cardiovascular and respiratory systems is more dangerous and affects some communities more than others.
Biodegradable sensor monitors levels of pesticides via direct contact with surface of fruit and vegetables
A single-photon detector (SPD) is sensitive to incidence of individual quanta of light and has many applications in photonics, such as fluorescence measurements, laser ranging, optical time-domain reflectometer, and quantum optics experiments.
A sleeker facial recognition technology tested on Michelangelo's David
Researchers at the University of São Paulo (USP) and the Federal University of Viçosa (UFV) in Brazil have developed a sustainable sensor that can be placed directly on the surface of a vegetable or fruit to detect the presence of pesticides. Known for this reason as "plant-wearable," it is made of cellulose acetate, a material derived from wood pulp.
Mathematical model reveals how a pit viper is able to find its dinner in the dead of night
Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report in Nano Letters a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of...
Ambitious workers park the office politics when employer is struggling, study suggests
In the animal kingdom, there are many grand examples of species that make sense of their world by expertly deciphering even weak signals from their surroundings.
Asteroid making its closest approach to Earth this week
New research from a team at City, University of London sheds light on how perceived threats and opportunities to their teams affect office politics.
Handwashing is a major source of pet pesticide pollution in UK rivers, finds study
On 4 February, asteroid 2011 MD will make its closest approach to the Earth. Though it will not be visible with the naked eye, the asteroid will pass 15,000,000 km away from Earth—much closer than those in the asteroid belt and less than 10% of the distance from Earth to its next nearest planet, Mars.
Researchers use supercomputer to determine whether 'molecules of life' can be formed naturally in right conditions
A new study reveals that handwashing in the weeks after spot-on flea and tick treatments is the largest source of pet pesticide pollution in rivers.
What we could learn from first reported footage of a newborn great white shark
Basic biology textbooks will tell you that all life on Earth is built from four types of molecules: proteins, carbohydrates, lipids, and nucleic acids. And each group is vital for every living organism.
Nondestructive technique for identifying nuclides using neutron resonance transmission analysis
It has been reported that a newborn great white shark was spotted off the southern coast of California—the first time one has been seen in the wild, experts believe.
A feasibility study conducted at CSNS Back-n facility, recently published in Nuclear Science and Techniques, demonstrates a significant prospect of NRTA in nondestructive nuclide identification.
