Environmental oxygen triggers loss of webbed digits

African clawed frog (stock image). Credit: © Nathan / Adobe Stock Free fingers have many obvious advantages on land, such as in locomotion and grasping, while webbed fingers are typical of aquatic or gliding animals. But both amphibians and amniotes -- which include mammals, reptiles, and birds -- can have webbed digits. In new research…

Genetic discovery holds implications for better immunity, longer life

Caenorhabditis elegans (stock image). Credit: © heitipaves / Adobe Stock Wrinkles on the skin of a microscopic worm might provide the key to a longer, healthier life for humans. Working with Caenorhabditis elegans, a transparent nematode found in soil, researchers at Washington State University's Elson S. Floyd College of Medicine were the first to find…

The difference between an expert’s brain and a novice’s

Neurons illustration (stock image). Credit: © whitehoune / Adobe Stock When mice learn to do a new task, their brain activities change over time as they advance from 'novice' to 'expert.' The changes are reflected in the wiring of cell circuits and activities of neurons. Using a two-photon imaging microscope and a wealth of genetic…

Amazon deforestation and number of fires show summer of 2019 not a ‘normal’ year

Burning in Amazon rainforest (stock image). Credit: © Marcio Isensee e Sá / Adobe Stock The fires that raged across the Brazilian Amazon this summer were not 'normal' and large increases in deforestation could explain why, scientists show. The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at…

Ketogenic diet helps tame flu virus

Influenza virus illustration (stock image). Credit: © Axel Kock / Adobe Stock A high-fat, low-carbohydrate diet like the Keto regimen has its fans, but influenza apparently isn't one of them. Mice fed a ketogenic diet were better able to combat the flu virus than mice fed food high in carbohydrates, according to a new Yale…

Extinct giant ape directly linked to the living orangutan

Modern-day orangutan (stock image). Credit: © Stéphane Bidouze / Adobe Stock By using ancient protein sequencing, researchers have retrieved genetic information from a 1.9 million year old extinct, giant primate that used to live in a subtropical area in southern China. The genetic information allows the researchers to uncover the evolutionary position of Gigantopithecus blacki,…

Experts unlock key to photosynthesis, a find that could help us meet food security...

Green leaf in sunlight (stock image). Credit: © Korn V. / Adobe Stock Scientists have solved the structure of one of the key components of photosynthesis, a discovery that could lead to photosynthesis being 'redesigned' to achieve higher yields and meet urgent food security needs. The study, led by the University of Sheffield and published…

Could cytotoxic T-cells be a key to longevity?

Elderly man's hands on cane (stock image). Credit: © sergign / Adobe Stock Scientists from the RIKEN Center for Integrative Medical Science (IMS) and Keio University School of Medicine in Japan have used single-cell RNA analysis to find that supercentenarians -- meaning people over the age of 110 -- have an excess of a type…

NASA finds Neptune moons locked in ‘dance of avoidance’

Screenshot of animation illustrating how the odd orbits of Neptune's inner moons Naiad and Thalassa enable them to avoid each other as they race around the planet. Credit: NASA/JPL-Caltech Even by the wild standards of the outer solar system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to newly published research.…

Ancient Egyptians gathered birds from the wild for sacrifice and mummification

Ibis (stock image). Credit: © kajornyot / Adobe Stock In ancient Egypt, Sacred Ibises were collected from their natural habitats to be ritually sacrificed, according to a study released November 13, 2019 in the open-access journal PLOS ONE by Sally Wasef of Griffith University, Australia and colleagues. Egyptian catacombs are famously filled with the mummified…
