Genetic analysis shows head lice evolution mirrors human migration and colonization in the Americas
A new analysis of lice genetic diversity suggests that lice came to the Americas twice—once during the first wave of human migration across the Bering Strait, and again during European colonization. Marina Ascunce, currently at the USDA-ARS, and co.....»»
Ultra Retina XDR OLED screens in iPad Pro are just the latest evolution of Apple"s flagship display tech
The iPad Pro line has boasted Apple's flagship display technology for the last six years, starting with a ProMotion LED display, stopping at at miniLED backlighting for a while, then arriving at tandem OLED. Here's how they compare.iPad Pro display t.....»»
Study underscores new strategies to fight drug-resistant bacteria
Several billion years ago, a genetic arms race began between bacteria and their viral killers. This seemingly eternal struggle continues today, with implications for diseases killing tens of thousands of people around the world each year......»»
Study shows female gamers only label half of sexual harassment incidents they experience as such
A new study from the Kinsey Institute reveals that only 50.5% of women who were targets of sexual harassment during online gaming identified qualifying incidents as such. This figure dropped further to only 42.2% for women who witnessed sexual harass.....»»
Researchers study the intricacies of homologous recombination and abnormal chromosome bridges
Keeping the genetic information stored in genomic DNA intact during the cell division cycle is crucial for almost all lifeforms. Extensive DNA damage invariably causes various adverse genomic rearrangements, which can lead to cell death in the best c.....»»
Roundup: Hands-on with the new M4 iPad Pro and Magic Keyboard
Apple today officially unveiled the future of its iPad product category with new iPad Air and iPad Pro lineups. Apple invited influencers and members of the press to New York City and London to go hands-on with the devices. Head below for a roundup o.....»»
Chimps shown to learn and improve tool-using skills even as adults
Chimpanzees continue to learn and hone their skills well into adulthood, a capacity that might be essential for the evolution of complex and varied tool use, according to a study published May 7 in the open-access journal PLOS Biology by Mathieu Malh.....»»
Global meta-analysis quantifies benefits of cover crop use
For years, both scientists and farmers have debated whether the use of cover crops—plants used to cover the ground after harvesting of main crops—have a positive or negative impact on subsequent crop yield. Hundreds of studies have been performed.....»»
More feelings of misinformation lead to more news avoidance, study shows
As people have more difficulty distinguishing fact from fiction in the United States, they are more likely to feel news fatigue and avoid news altogether, according to a University of Michigan study......»»
Engineers develop innovative microbiome analysis software tools
Since the first microbial genome was sequenced in 1995, scientists have reconstructed the genomic makeup of hundreds of thousands of microorganisms and have even devised methods to take a census of bacterial communities on the skin, in the gut, or in.....»»
Using algorithms to decode the complex phonetic alphabet of sperm whales
The allure of whales has stoked human consciousness for millennia, casting these ocean giants as enigmatic residents of the deep seas. From the biblical Leviathan to Herman Melville's formidable Moby Dick, whales have been central to mythologies and.....»»
What are nanoplastics? An engineer explains concerns about particles too small to see
It's become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastic.....»»
Loss of large herbivores affects interactions between plants and their natural enemies, study shows
Insects and microorganisms that feed on plants, cut up leaves, modify leaf tissue or produce leaf spots and other kinds of damage, are usually known as pests and considered harmful, yet interactions between plants and their natural enemies are import.....»»
Microbiome studies help explore treatments for genetic disorders
A collaboration has led to the identification, in a bacterium of the intestine, of new CRISPR-Cas9 molecules that could have a clinical potential to treat genetic diseases such as retinitis pigmentosa, through sub-retinal injections. Anna Cereseto an.....»»
Laboratory and natural strains of intestinal bacterium turn out to have similar mutational profiles
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected......»»
Hades 2 shows the Steam Deck’s biggest advantage over the Nintendo Switch
The Steam Deck still has one important advantage over the Nintendo Switch, and Hades 2 reveals it......»»
Dogma-challenging telomere findings may offer new insights for cancer treatments
A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of chromosomes, and that impairing this process can.....»»
Discharge of scrubber water into the Baltic Sea is responsible for hundreds of millions in costs
Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study from Chalmers University of Technology, Sweden, shows that these emissions caused pollution corresponding to socioeconomic costs of more than €680 milli.....»»
Self-adaptive system for temperature control: A dynamically controllable strategy for healing wound tissue
Skin functions as a sophisticated sensorial system in the human body, capable not only of detecting environmental stimuli—such as temperature, pressure, strain, and vibration—but also of actively responding to these changes. Among these, the temp.....»»
Research team develops fast-track process for genetic improvement of plant traits
Researchers interested in improving a given trait in plants can now identify the genes that regulate the trait's expression without doing any experiments......»»
Team describes MXene-supported PtCo bimetallic catalyst for hydrogen evolution in acidic conditions
Hydrogen energy is considered a promising solution with high energy density and zero pollution emissions. Currently, hydrogen is mainly derived from fossil fuels, which increases energy consumption and greenhouse gas emissions, hindering efforts to a.....»»
