Maternal stress during pregnancy may shorten lifespans of male lizard offspring
Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with.....»»
Genetic variants underlying male bisexual behavior, risk-taking linked to more children, study suggests
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future......»»
Male southern elephant seals are picky eaters, study suggests
As one of the top predators roaming Antarctica, the sizeable southern elephant seal has its fair selection of the menu. But it turns out they don't just want to eat anything and everything......»»
Future labor losses due to heat stress in China under climate change scenarios
Climate change is the biggest global health threat in the 21st century, and the rising temperatures have undermined the health and safety of the working population, as well as caused labor losses, which are closely tied to social-economic development.....»»

Nanoparticles with antibacterial action could shorten duration of tuberculosis treatment
A low-cost technology involving nanoparticles loaded with antibiotics and other antimicrobial compounds that can be used in multiple attacks on infections by the bacterium responsible for most cases of tuberculosis has been developed by researchers a.....»»
Machine learning unveils new insights into stress responses for plant health diagnosis
Leaf color patterns, influenced by factors such as leaf age and environmental stress, serve as indicators of plant health in agriculture. The VIS-NIR-SWIR sensor, though effective in measuring these patterns with high resolution, has been limited to.....»»
Field-induced superconductivity in quantum materials
Field-induced superconductivity occurs when an applied magnetic field increases or induces superconductivity. In a new report published in Science Advances, Joshua J. Sanchez and a team of scientists applied stress as a switch between a field tunable.....»»

Environmental stress rather than genetics influenced height differences in early Neolithic people: Study
The difference in height between female and male individuals in northern Europe during the Early Neolithic (8,000–6,000 years before present, bp) may have been influenced by cultural factors, a paper published in Nature Human Behaviour suggests. Th.....»»

Genetic mutations that promote reproduction tend to shorten human lifespan, study shows
A University of Michigan-led study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence......»»
Researchers quantify the onset of turbulence in a pipe bent back on itself

Orangutan male success not due to dominance alone, study finds
In primates, the biggest, bossiest males usually get to father the most offspring; and for a long time it was thought that this rule applied to orangutans too. Male orangutans openly compete; and it's the older males with hefty cheek pads, known as ".....»»
Biases behind transgender athlete bans are deeply rooted

Ocean acidification creates legacy of stress for red abalone, study finds
Stressful childhoods can affect an individual's adult years and influence future generations. Scientists at the University of California, Davis, found a similar pattern holds true for red abalone exposed as babies, and again as adults, to the stress.....»»
Study identifies organic alternative for fighting cattle-pestering flies
When cattle are fighting flies in the summer, they gather in tight bunches, leading them to eat less while experiencing more stress and discomfort. Beef producers have limited options for controlling the flies that pester their cattle. Moreover, exis.....»»
