Born to be a cannibal: Genes for feeding behaviour in mandarin fish identified

4 years ago from Physorg

Some mandarin fish species (Sinipercidae) are pure fish-eaters, which feed exclusively on living juvenile fish—also of their own species. A research team led by the Chinese Huazhong Agricultural University (HZAU)...

Chinook salmon declines related to changes in freshwater conditions

4 years ago from Physorg

A new University of Alaska-led study provides the first evidence that declines in many of Alaska's chinook salmon populations can be attributed in part to climate-driven changes in their freshwater...

Overharvesting threatens 'Himalayan Viagra' fungus: IUCN

4 years ago from Physorg

A parasitic fungus that grows inside the ghost moth caterpillar and then kills its host by bursting through its head is itself threatened with extinction, the IUCN said Thursday, as...

Cycad stem cuttings need wound sealants for successful propagation

4 years ago from Physorg

The need to cover an open wound on cycad stem cuttings has been confirmed by the Western Pacific Tropical Research Center at the University of Guam in a study published...

Daytime aardvark sightings are a sign of troubled times

4 years ago from Physorg

Aardvarks occur across most of sub-Saharan Africa, but very few people have seen one, because they are solitary, mostly active at night, and live in burrows. They use their spade-like...

Unraveling the mystery of wheat herbicide tolerance

4 years ago from Physorg

Genetically speaking, the loaf of bread you stress-baked during the COVID-19 shutdown is more complex than you think. Wheat's 16 billion genes, organized in not one but three semi-independent genomes,...

X-ray scattering shines light on protein folding

4 years ago from Physorg

KAIST researchers have used an X-ray method to track how proteins fold, which could improve computer simulations of this process, with implications for understanding diseases and improving drug discovery. Their...

Overzealous cell membrane guardians could increase the risk of cancer

4 years ago from Physorg

Researchers at the UiO and OUS have discovered how destructive changes occur in our genome. This could lead to cancer. Their results have been published in the journal Nature Cell...

Nearly all Madagascar's lemur species 'face extinction'

4 years ago from Physorg

Almost all species of lemur, the small saucer-eyed primates native to Madagascar, face extinction, an international conservation body warned on Thursday, adding to its growing list of animals and plants...

Company offers $1,000 to play 50 hours of 'Animal Crossing'

4 years ago from UPI

An online company is offering Nintendo fans the chance to make $1,000 with an unusual dream job: playing "Animal Crossing: New Horizons" for 50 hours.

Discovery makes microscopic imaging possible in dark conditions

4 years ago from Science Daily

Researchers have discovered a new way to more accurately analyze microscopic samples by essentially making them 'glow in the dark', through the use of chemically luminescent molecules. Current methods of...

Sodium found to regulate the biological clock of mice

4 years ago from Science Daily

A new study shows that increases in the concentrations of blood sodium can have an influence on the biological clock of mice, opening new research avenues for potentially treating the...

New form of melanin has ability to protect human tissue from X-rays

4 years ago from Science Blog

Packing for outer space? Here’s one thing you won’t want to forget. Northwestern University researchers have synthesized a new form of melanin enriched with selenium. Called selenomelanin, this new biomaterial...

OPTN-ATG9 interaction accelerates autophagic degradation of ubiquitin-labeled mitochondria

4 years ago from Physorg

Researchers at TMIMS have revealed that PINK1 (a serine/threonine kinase) and Parkin (a ubiquitin ligating enzyme: E3) work together to ubiquitylate the outer membrane proteins of damaged mitochondria to induce...

Evolution makes the world less ragged

4 years ago from Science Daily

How does evolution impact ecological patterns? It helps smooth out the rough edges, say researchers. A new review of the history of ecological and evolutionary research establishes a framework to...

How can we stop people wanting to buy illegal wildlife products?

4 years ago from Physorg

Conservationists have been working for decades to save species such as pangolins and rhinos from illegal hunting and trading. And, with fears that the coronavirus pandemic originated from the wildlife...

Discovery opens up new path in study of marine evolution and biodiversity

4 years ago from Physorg

New UCLA research indicates that an evolutionary phenomenon never before observed among marine life could help explain why there is such immense biodiversity in the world's coral reefs and the...

Doing more with less: Sperm without a fully active tail move faster and more efficiently, new study finds

4 years ago from Physorg

Sperm cells moving their long tail to swim through the body in search of an egg is a familiar image, but a fully 'powered' tail may not be the key...

Higher fruit, vegetable and whole grain intake linked to lower risk of diabetes

4 years ago from Science Daily

Higher consumption of fruit, vegetables and whole grain foods are associated with a lower risk of developing type 2 diabetes, according to two new studies.

Biologists trace plants' steady mitochondrial genomes to a gene found in viruses, bacteria

4 years ago from Physorg

One could say that mitochondria, the energy-producing organelles inside every human cell, dance to their own beat. After all, they have their own genome—a set of DNA-containing chromosomes—completely separate from...

Scientists look to bird feathers for printing colors

4 years ago from Physorg

In nature, colors play a vital role in behaviors such as pollination, signaling for mating and defense against predators. Colors are also an important factor in scientific research that can...
