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.....»»
First map of vegetation across Antarctica reveals a battle for the continent"s changing landscape
A tiny seed is stuck between loose gravel and coarse sand. There is nothing else alive around it. All it can see is a wall of ice reaching 20 meters up into the sky. It is cold. Survival is hard around here. In winter, it is dark even during the day......»»
Bacteria encode hidden genes outside their genome; do we?
Since the genetic code was first deciphered in the 1960s, our genes have seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why.....»»
Male and female lions socialize differently throughout their lives, study reveals
New research from the University of Oxford on wild lions has revealed that males and females experience vastly different changes to their social network throughout their lives, and that this may shape their survival......»»
Heat stress survival: Unraveling the HsfA2-ACTIN dynamics in lily varieties
A research team has identified that the heat stress transcription factor HsfA2 and actin-interacting protein (AIP) LACTIN interact at the protein level in Lilium longiflorum "White Heaven," mediating gene expression and protecting cells from heat str.....»»
When is Once Human coming to consoles?
Once Human has exploded in popularity on Steam, but is that the only place you can play the hit survival game? Will Once Human come to PlayStation or Xbox?.....»»
"Baby talk:" Decoding how children"s vocal and cognitive cues sway adults
Compared to other mammals, human children are dependent on their caregivers for a remarkably long time. Throughout the ages, they have developed "psychological tactics" to endear themselves to adults and thus enhance their chances of survival. This p.....»»
Horse miscarriages offer clues to causes of early human pregnancy loss
A study of horses—which share many important similarities with humans in their chromosomes and pregnancies—revealed that 42% of miscarriages and spontaneous abortions in the first two months of pregnancy were due to complications from an extra se.....»»
Path to precision: Targeted cancer drugs go from table to trials to bedside
What started in a scientist's dining room is now in tissue-agnostic combo trials. Enlarge (credit: Aurich Lawson) In 1972, Janet Rowley sat at her dining room table and cut tiny chromosomes from photographs she had taken.....»»
Platypus and chicken reveal how chromosomes balance between the sexes
UNSW Sydney researchers have made new discoveries of fundamental differences in biological processes between males and females—by interrogating the unique and diverse sex chromosome systems of the platypus and the chicken......»»
Winter breeding offers lifeline for monarch butterflies in Northern California
Monarch butterflies in Northern California are adapting to a changing climate by embracing an unexpected strategy: breeding in the winter. The shift could be key to the survival of the iconic insect, according to a new study published in the Journal.....»»
Rare rodent prefers an invasive noxious weed over native vegetation, study finds
In a twist to the native animal survival story, new research shows that a threatened rodent that only survives on offshore islands prefers one of Australia's most invasive weeds for food and shelter......»»
Exclusive clip from Syfy’s The Ark teases the arrival of new crew members
Ark One welcomes new members aboard their survival ship in an exclusive clip from the next episode of Syfy's The Ark......»»
New liquid single nucleotide polymorphism chip can enhance rubber tree breeding
A research team developed and validated a liquid single nucleotide polymorphism (SNP) chip named "HbGBTS80K," which includes 80,080 SNPs evenly distributed across 18 chromosomes. This SNP chip effectively distinguished 404 rubber accessions into four.....»»
New hope for critically endangered Siamese crocodile
Sixty Siamese crocodiles, from five separate nests, have successfully hatched in Cambodia's Cardamom National Park—the largest record of this species breeding in the wild this century and a massive boost for the survival prospects of this criticall.....»»
New model explains precise timing of viral cell bursting
New research from Rice University scientists is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena......»»
New fossil snake species provides insight into reptile social behavior and development
A newly discovered snake species, Hibernophis breithaupti, provides rare insight into the social behavior of snakes and fills some gaps in our knowledge of the evolution of boas, or boidae. The quartet of fossilized snakes discovered in western Wyomi.....»»
Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants
Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two disti.....»»
Scientists unravel transition of survival strategies in grape family
In a study published in Nature Plants, scientists have identified the Eocene, Oligocene, and Miocene boundaries as turning points for the transition of survival strategies in the grape family (Vitaceae)......»»
Lions in a Uganda park make a perilous journey across a 1.5 km stretch of water to find mates
Domestic cats will do almost anything to avoid contact with water. Not so for their wild cousins, though. Lions, tigers and jaguars have had to adapt to water and sometimes take the plunge for survival......»»
A stealth fungus has decimated North American bats, but scientists may be a step closer to treating white-nose syndrome
An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, wh.....»»
