Whole genomes map pathways of chimpanzee and bonobo divergence
Chimpanzees and bonobos are sister species that diverged around 1.8 million years ago as the Congo River formed a geographic boundary and they evolved in separate environments. Now, a whole-genome comparison of bonobos and chimpanzees reveals the gen.....»»
Genomes from 240 mammalian species reveal what makes the human genome unique
Over the past 100 million years, mammals have adapted to nearly every environment on Earth. Scientists with the Zoonomia Project have been cataloging the diversity in mammalian genomes by comparing DNA sequences from 240 species that exist today, fro.....»»
Information "deleted" from the human genome may be what made us human
What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and th.....»»
Sophisticated gene memory: Researchers develop new method to genetically compare hundreds of animal species
Thanks to great technological advances, the genetic material of living beings can now be sequenced at a rapid rate. Comparisons of genomes, whether of closely related or completely different species, reveal particularly interesting findings. In this.....»»
Man peddling vitamins as cancer therapy faces 5 felony counts
With allegedly fake title, Gevorkian sold unproven treatments for serious conditions. Enlarge (credit: Pathways) A man in California is facing five felony charges for allegedly posing as a licensed doctor while providing.....»»
Advanced X-ray technique unveils fast solid-gas chemical reaction pathways
For the rational design of new material compounds, it is important to understand the mechanisms underlying their synthesis. Analytical techniques such as nuclear magnetic resonance and spectroscopy are usually employed to study such mechanisms in mol.....»»
If it pays to be a jerk, why isn"t everyone that way? A chimpanzee study offers insight
Throw a tantrum. Threaten, shove aside or steal from your colleagues. Science confirms, yet again, that brutish behavior can be an effective path to power. And not just in humans, but in chimpanzees, too......»»
Newly sequenced hornet genomes could help explain invasion success
The genomes of two hornet species, the European hornet and the Asian hornet (or yellow-legged hornet) have been sequenced for the first time by a team led by UCL (University College London) scientists......»»
Fungal genetics could help develop novel biotechnologies
An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in th.....»»
New effort IDs the genes that made the mammoth
Shaggy fur, cold tolerance, and cancer resistance may all be in the genes. Enlarge (credit: Beth Zaiken) An international team of scientists has published the results of their research into 23 woolly mammoth genomes in C.....»»
Woolly mammoths evolved smaller ears and woolier coats over the 700,000 years that they roamed the Siberian steppes
A team of researchers compared the genomes of woolly mammoths with modern day elephants to find out what made woolly mammoths unique, both as individuals and as a species. The investigators report April 7 in the journal Current Biology that many of t.....»»
Male beetles neglect their genomes when competing for females
Male beetles face a trade-off between competing with other males for mating opportunities and repairing damage to their sperm DNA, according to a study published April 4 in the open access journal PLOS Biology by Mareike Koppik from Uppsala Universit.....»»
Study finds degree of asexual reproduction in liverwort plants is hormonally controlled
Asexual, or vegetative, reproduction in plants is controlled by environmental conditions, but the molecular signaling pathways that control this process are poorly understood. Recent research suggests that the KAI2-ligand (KL) hormone is responsible.....»»
A machine learning framework to predict and quantify synthesis difficulties for designer chromosomes
Artificially synthesizing genomes has broad prospects in fields such as medical research and developing industrial strains. From the synthesis of the artificial life JCVI-syn1.0 by Craig Venter's team in 2010, to the rewriting and synthesis of the pr.....»»
Worm genetics reveal important pathways for sleep regulation
Although the regulation of sleep—how much, when, and how sleep occurs—is mainly considered to be controlled by the brain, sleep deprivation also affects the body, and signals from the body can affect sleep. However, the ways in which the body reg.....»»
The journey of a carbon atom: From space, NASA"s PACE mission detects carbon in the sky, land and sea
Whether in plants or animals, greenhouse gases or smoke, carbon atoms exist in various compounds as they move through a multitude of pathways within Earth's system. That's why NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission—schedule.....»»
Hunter-gatherer genes helped early European farmers survive disease, reveals study
When early Stone Age farmers first moved into Europe from the Near East about 8,000 years ago, they met and began mixing with the existing hunter-gatherer populations. Now genome-wide studies of hundreds of ancient genomes from this period show more.....»»

Researchers prepare for quantum sensing in outer space
As part of a new NASA Quantum Pathways Institute consisting of a multi-university research team, UC Santa Barbara professor of electrical and computer engineering Daniel Blumenthal will help to build technology and tools to improve measurement of imp.....»»
Ants avoid reproductive competition with close relatives, suggests study
Cooperation is a key innovation in evolution, from evolution of genomes and multicellular organisms to insect societies, such as ants and honeybees to human societies. Crucially, any cooperation is stable only when conflicts among group members are k.....»»
