More evidence of an evolutionary "arms race" between genes and selfish genetic elements
The human genome is littered with selfish genetic elements, which do not seem to benefit their hosts, but instead seek only to propagate themselves......»»
NASA satellites reveal abrupt drop in global freshwater levels
An international team of scientists using observations from NASA-German satellites found evidence that Earth's total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the r.....»»
Genes of ancient animal relatives used to grow a mouse: Study reveals hidden history of stem cells
An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that p.....»»
Study uncovers earliest evidence of humans using fire to shape the landscape of Tasmania
Some of the first human beings to arrive in Tasmania, over 41,000 years ago, used fire to shape and manage the landscape, about 2,000 years earlier than previously thought......»»
Evo—an AI-based model for deciphering and designing genetic sequences
Computer scientists, bioengineers and AI specialists from the Arc Institute and Stanford University have developed an AI-based model capable of decoding and designing genetic sequences. In their paper published in the journal Science, the group descr.....»»
Study confirms Egyptians drank hallucinogenic cocktails in ancient rituals
A University of South Florida professor found the first-ever physical evidence of hallucinogens in an Egyptian mug, validating written records and centuries-old myths of ancient Egyptian rituals and practices. Through advanced chemical analyses, Davi.....»»
Curly-Tailed Cats Communicate with an ‘Accent’
A genetic mutation makes some cats’ tail curl over their back, giving them something akin to an accent when they communicate with other kitties.....»»
Discovery of 2,586 orphan genes in Rosa chinensis reveals stress adaptation and flower development
Orphan genes, found only in specific lineages, are key drivers of new functions and phenotypic traits. This discovery lays a foundation for understanding how roses thrive under environmental challenges......»»
Water under Threat, Wooden Satellites and a Mud Bath for Baseballs

Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»
Q&A: Holobiont biology, a new concept for exploring how microbiome shapes evolution of visible life
Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new species of animals and plants, according to Seth Bordenstei.....»»
Scientists identify flaw in astrophysics models of massive stars and supernovae
An international team of researchers has uncovered evidence that astrophysics models of massive stars and supernovae are inconsistent with observational gamma-ray astronomy......»»
Meteorite contains evidence of liquid water on Mars 742 million years ago
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue University and is one of the few meteorites that can be traced.....»»
More evidence that Europe"s ancient landscapes were open woodlands: Study finds oak, hazel and yew were abundant
In 2023 a research group from Aarhus University in Denmark found that light woodland and open vegetation dominated Europe's temperate forests before Homo sapiens. In a new study, recently published in the Journal of Ecology, they take a closer look a.....»»
Racism is such a touchy topic that many US educators avoid it. How we tackled that challenge head on
It is not easy to teach about race in today's political and social climate......»»
Bioluminescent proteins made from scratch enable non-invasive, multi-functional biological imaging
Bioluminescence is the natural chemical process of light creation in some living creatures that makes fireflies flicker and some jellyfish glow. Scientists have long been interested in borrowing the secrets of these animals' light-producing genes to.....»»

A new AAA game set in the Avatar universe was announced by Saber Interactive. Let's master the elements together and learn everything we can about the game......»»
Using CRISPR to decipher whether gene variants lead to cancer
In recent years, scientists have created a range of new methods based on CRISPR-Cas technology for precisely editing the genetic material of living organisms. One application is in cell therapy: A patient's immune cells can be specifically reprogramm.....»»
Great Britain lags behind Europe on restricting gambling marketing, new research shows
A new study, by the University of Bristol and Ipsos, adds to mounting evidence showing gambling marketing needs much stricter national regulation......»»
Study reveals why carbon boosts metal nanoparticle catalysts
Precious metals play an important role in the chemical industry as catalysts: With the help of silver, platinum, palladium or other elements, chemical reactions can take place that would otherwise not progress or would only progress at a much lower r.....»»
New CRISPR system for gene silencing doesn"t rely on cutting DNA
Scientists from Vilnius University's (VU) Life Sciences Center (LSC) have discovered a unique way for cells to silence specific genes without cutting DNA. This research, led by Prof. Patrick Pausch and published in the journal Nature Communications,.....»»
