Snake sex chromosomes say less about sex and more about survival
Sex-specific chromosomes are a dangerous place to be, if you're a gene. Because these chromosomes—Y chromosomes, in humans—do not have a matching chromosome with which to exchange genetic information, they are prone to losing non-essential genes.....»»
Defect engineering for advanced electrocatalytic conversion of nitrogen-containing molecules
The nitrogen cycle, one of the most important biochemical cycles in all ecosystems, plays a key role in human survival and development. It describes the interconversion process between elementary nitrogen substances and nitrogen-containing compounds.....»»
How elasmobranch species fared during and after the K-Pg mass extinction event
A pair of researchers, Guillaume Guinot and Fabien Condamine, both with Université de Montpellier, in France, has looked at the impact of the Cretaceous–Paleogene (K-Pg) extinction event on elasmobranch species to learn more about survival of mari.....»»
Changes of Tibetan religious activities during the past millennium revealed from lake sediments
Xiahe County, located in Gannan Tibetan Autonomous Prefecture in the northeastern part of the Tibetan Plateau, is known as "Little Tibet." For a long time, all aspects of human survival, social development and cultural accumulation in the region have.....»»
New angle on theory explaining species diversity in rainforest trees
A new study led by a researcher of the Oranim Campus of the University of Haifa, published in the journal Nature, has found that in conditions of high soil humidity the chances of survival of young tree seedlings growing at high densities are reduced.....»»
Narwhals" climate-vulnerable winter feeding crucial for survival: study
Narwhals are likely more dependent on fat reserves and abundant prey in climate-threatened winter habitats than previously thought, researchers said Wednesday, warning of severe risks posed by global warming......»»
Scientists make stunning discovery, find new protein activity in telomeres
Once thought incapable of encoding proteins due to their simple monotonous repetitions of DNA, tiny telomeres at the tips of our chromosomes seem to hold a potent biological function that's potentially relevant to our understanding of cancer and agin.....»»

Endangered African penguin chicks hatch at Arizona aquarium
An Arizona aquarium is celebrating the hatching of three endangered African penguin chicks, saying the tiny additions are genetically valuable as zoos and aquariums around the world work to ensure the species' survival through breeding programs and c.....»»
Novel method to accurately measure key marker of biological aging
Telomeres—the caps at the ends of chromosomes that protect our genetic materials from the brunt of cellular wear and tear—are known to shorten and fray over time. Lifestyle, diet and stress can exacerbate this process, leading to early loss of te.....»»

Independent craft brewers were able to weather the COVID pandemic by taking risks and being innovative, a new study has revealed......»»
A mega port in India threatens the survival of the largest turtles on Earth
In a remote archipelago at the southernmost tip of India lies the Great Nicobar Island. This pristine ecosystem is a globally important nesting site of the largest turtles on Earth—leatherback turtles. But now, the site is threatened by a massive i.....»»
The not so inactive X chromosome
Nearly every cell in our body contains pairs of each of our chromosomes, and these pairs are identical in all but one case: that of our sex chromosomes. Males typically have one X and one Y sex chromosome, while females typically have two X chromosom.....»»
Cells routinely self-cannibalize to take out their trash, aiding in survival and disease prevention
Don't let the textbook diagram of a simplified two-dimensional cell fool you—within this tiny structure of life is a complex universe of molecular machinery that is continually being built, put into motion and eventually broken down......»»
Harnessing an innate protection against Ebola
In their evolutionary battle for survival, viruses have developed strategies to spark and perpetuate infection. Once inside a host cell, the Ebola virus, for example, hijacks molecular pathways to replicate itself and eventually make its way back out.....»»
Combating severe cancer with a new drug delivery system
Peritoneal cancer is difficult to treat and has a poor survival prognosis. But a new and effective nanomedicine delivery system is offering some hope......»»
Newly-named species of tree-dwelling snakes threatened by mining
Five new tree-dwelling snake species were discovered in the jungles of Ecuador, Colombia, and Panama. Conservationists Leonardo DiCaprio, Brian Sheth, Re:wild, and Nature and Culture International chose the names for three of them in honor of loved o.....»»
Rare orchids could be saved by common fruits in Florida, research finds
Florida's night orchid is at risk of extinction, but backyard fruit trees could hold the key to their survival......»»
Family tree of major snake group rewritten and new branch of snakes found
An international team has been able to reconstruct the evolutionary tree of a major group of snakes, Elapoidea, that has proved to be a significant step towards the construction of a complete Tree of Life for snakes......»»
