A new method to study lithium dendrites could lead to better, safer batteries

Lithium ion batteries often grow needle-like structures between electrodes that can short out the batteries and sometimes cause fires. Now, an international team of researchers has found a way to grow and observe these structures …

‘Bilingual’ molecule connects two basic codes for life

The nucleic acids of DNA encode genetic information, while the amino acids of proteins contain the code to turn that information into structures and functions. Together, they provide the two fundamental codes underlying all …

Hubble detects smallest known dark matter clumps

When searching for dark matter, astronomers must go on a sort of “ghost hunt.” That’s because dark matter is an invisible substance that cannot be seen directly. Yet it makes up the bulk of the universe’s mass and forms the …

Goldilocks stars are best places to look for life

To date astronomers have discovered over 4,000 planets orbiting other stars. Statistically, there should be over 100 billion planets in our Milky Way galaxy. They come in a wide range of sizes and characteristics, largely …

Of ants and men: Ant behavior might mirror political polarization

Could the division of labor in an anthill be driven by the same social dynamics governing the gap between liberals and conservatives? That was the surprising question tackled by Princeton biologists Chris Tokita and Corina …

African grey parrots spontaneously ‘lend a wing’

People and other great apes are known for their willingness to help others in need, even strangers. Now, researchers reporting in Current Biology on January 9 have shown for the first time that some birds—and specifically …

Decoding hidden brain chatter to advance neuroprostheses

Once you learn a skill like tying your sneakers, you can perform it consistently over the years. This suggests the neural activity in the brain associated with the skill remains stable over time.

Missing protein in brain causes behaviors mirroring autism

Scientists at Rutgers University-Newark have discovered that when a key protein needed to generate new brain cells during prenatal and early childhood development is missing, part of the brain goes haywire—causing an imbalance …

An out-of-the-box attack on diabetes

A protein newly identified as important in type 1 diabetes can delay onset of the disease in diabetic mice, providing a new target for prevention and treatment in people, according to research led by scientists at the U.S. …

In fighting gut infections, nervous system is key, team finds

The peaceful and delicate co-existence of friendly gut bacteria and the immune system relies on highly coordinated information exchange between immune system cells and certain cells lining the intestine. Until now, scientists …

Bandage material helps stop bleeding without adhering to the wound

Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot and doesn’t stick to the wound. This marks the first time that scientists have combined both …

The claw disease tyloma is primarily genetic in cows

Scientists at Martin Luther University Halle-Wittenberg (MLU) and Georg August University Göttingen have succeeded in proving that a claw disease in cows is primarily genetic. Until now, the occurrence of interdigital hyperplasia …

Randomness opens the gates to the land of attophotography

One of the last obstacles hindering the photography and filming of processes occurring on a scale of attoseconds, i.e. billionths of a billionth of a second, has disappeared. The key to its removal lies in the random nature …

Macroscopic spatial superposition

Wouldn’t it be fascinating to live in New York and London at the same time? In the standard of everyday life, this is equivalent to daydreaming or sheer fantasy. Nevertheless, this is a perfectly normal phenomenon in quantum …

Biologists identify pathways that extend lifespan by 500%

Scientists at the MDI Biological Laboratory, in collaboration with scientists from the Buck Institute for Research on Aging in Novato, Calif., and Nanjing University in China, have identified synergistic cellular pathways …

Stellar heavy metals can trace history of galaxies

Astronomers have cataloged signs of nine heavy metals in the infrared light from supergiant and giant stars. New observations based on this catalog will help researchers to understand how events like binary neutron star mergers …

A way to increase structural stability in strained halide perovskites

A team of researchers from the U.S., Saudi Arabia and Australia has structurally stabilized halide perovskites when under strain. In their paper published in the journal Nature, the group describes their approach and their …
