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.....»»
Quantifying cyber risk vital for business survival
Healthcare, manufacturing, and utilities are suffering long-term financial impact of major cyber attacks, according to ThreatConnect. “With the National Cyber Strategy coming out of the White House focusing on decreasing cyber risk from critical in.....»»
Study determines criteria for differentiating a pollinating insect from a presumed pollinator in the fossil record
Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing interest in studies on the origins of the relationship.....»»

Uncovering the secrets of how chromosomes assemble
Experiments using extracts from African clawed frog eggs have revealed how a key protein complex is regulated to assemble chromosomes during cell division. This finding could help to shed light on the development of certain cancers and birth defects.....»»
Natural selection among neural progenitor cells controls mammalian brain size
In nature, competition for survival among organisms or species is a fundamental evolutionary force, as described by Darwin's theory of natural selection. Similarly, in multicellular organisms, competitive interactions also occur between cells, creati.....»»
Timing of snowshoe hare winter color swap may leave them exposed in changing climate, study finds
Like many animals in the far north, snowshoe hares change their coats from brown to white each autumn. Come winter, these all-white hares are harder for predators to spot against the snowy landscape, helping ensure their survival......»»
Study predicts poor survival rates if Ebola infects endangered mountain gorillas
If infected with the Ebola virus, less than 20% of endangered mountain gorillas living in Africa's Virunga Massif region would be expected to survive more than 100 days past the first confirmed case. That is according to a study that used computer mo.....»»
How a worm"s embryonic cells change its development potential
Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differe.....»»

Can some snakes do cartwheels to escape or startle predators?
In research published in Biotropica, investigators report that the Dwarf Reed Snake (Pseudorabdion longiceps) performs cartwheels when threatened. This is the first time such an active rolling motion has been documented in snakes, with images and a d.....»»
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.....»»
Exploring a massive supercomplex in mitochondria comprising all four respiratory complexes
Eukaryotes generate the energy for survival through cellular respiration in mitochondria by a process known as the oxidative phosphorylation. In this process, nutrients and oxygen are converted into a chemical form of energy: ATP. This is achieved wi.....»»
Antarctic ice age survival story: Life seeking ice-free refuges imitates art in Ice Age, the movie
Antarctica is an icy place today, but the ice extended even further during past ice ages. The question of how and where life survived on land in the icy continent, through the ages, has long puzzled biologists......»»

Eels have fascinated us for ages—now we need to stop eating them, says researcher
Few animals have sparked humanity's curiosity as much as the eel (Anguilla anguilla). Until a recent past, this slimy, slippery, snake-shaped, incredibly agile fish inhabited virtually every body of water in Europe and Northern Africa, often in mind-.....»»
Boosting survival of a beneficial bacterium in the human gut
The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species—known as "good" bacteria—in the gut may enable medical interventions that promote gut and ove.....»»
What "Chernobyl dogs" can tell us about survival in contaminated environments
In the first step toward understanding how dogs—and perhaps humans—might adapt to intense environmental pressures such as exposure to radiation, heavy metals, or toxic chemicals, researchers have found that two groups of dogs living within the Ch.....»»
