We humans aren't the only animals that have to worry about bug bites. There are thousands of insect species that have evolved to specialize in feeding on different mammals and birds, but scientists are still learning how these bugs differentiate between species to track down their preferred prey. It turns out, the attraction might not even be skin-deep: a new study in Molecular Ecology found evidence that blood-sucking flies that specialize on bats may be locating their preferred hosts by following...

In a study published in the US journal Science Advances, a single cell type map of human tissues is presented. An open access atlas has been launched with more than 250,000 interactive plots to allow researchers to explore the expression in individual single cell types for all protein-coding genes in these tissues.

Greek authorities ordered additional fire patrols and infrastructure maintenance inspections Friday as the country grappled with a heat wave fed by hot air from Africa that is expected to last more than a week.

Two new publications examining cassava flowering reveal insights into the genetic and environmental factors underpinning one of the world's most critical food security crops.

Occurring faster than the speed of sound, the mystery behind the breakdown of plasma discharges in water is one step closer to being understood as researchers pursue applying new diagnostic processes using state-of-the-art X-ray imaging to the challenging subject.

Chemists create catalysts for use in industry and other applications. One of the methods to create these catalysts is by using light to break down organometallic compounds—substances that include both metals and carbon. These types of compounds are called photocatalysts. Scientists call the process of breaking down molecules with light, photodissociation. Researchers often study the photodissociation of iron pentacarbonyl as a model for understanding other catalysts. This study used a method called... Читать дальше...

Since the start of the COVID-19 pandemic, more parents of teenagers in the United States started buying firearms, according to a recent study.

The shelterwood forest system is a natural regeneration method of forest management that supplies the next generation of trees from overstory tree seeds without planting. This method lowers the cost of forest management by reducing the need for artificial reforestation through planting. This means that the understory trees must be preserved from felled trees during harvest.

Smallholder cereal crop systems are essential to food and nutritional security in most regions of the developing world. However, the productivity of most rice, maize and wheat fields is falling well short of its potential. One of the root causes is related to the inability of farmers to manage variability.

Arguably the most important (if least well known) industrial advancement of the 20th century, the Haber-Bosch ammonia synthesis process essentially conquered food scarcity by creating the means to mass produce fertilizer—fertilizer then used to fortify food harvests around the world.

Deploying residential heat pumps more widely across the United States has the potential to help reduce carbon pollution while also saving homeowners money, according to a new study by a University of Michigan researcher and colleagues.

"Many of the greatest challenges of our time, from clean energy to environmental justice, require new approaches to the craft of scientific experimentation. This is exceedingly apparent in the field of electron microscopy. As researchers utilize this powerful window to peer into the atomic machinery behind today's technologies, they are increasingly inundated with data and constrained by traditional operating models. We must leverage artificial intelligence and machine learning in our scientific... Читать дальше...

Researchers at the University of Virginia School of Medicine have overturned conventional wisdom on the workings of vital hormone receptors within cells, a finding that could boost drug development for diabetes and related metabolic disorders, cancer and other diseases.

In 2020, Colorado battled the four largest wildfires in its history, leaving residents anxious for another intense wildfire season this year.

"Single Sydneysiders hit hard by intimate partner bubble rule" was the headline last week, referring to the lockdown restrictions that prevented those living alone from having visitors not deemed to be an intimate partner.

China has opened the doors on what it bills as the world's largest planetarium, a slick new Shanghai facility showcasing the nation's recent extra-terrestrial exploits while notably downplaying those of space pioneers like the United States.

Scientists in Sardinia are hoping a thousand-year-old olive tree nearly destroyed by recent fires can be saved, mobilising volunteers to stand guard around the remains of the ancient tree.

A Russian space official on Friday blamed a software problem on a newly docked science lab for briefly knocking the International Space Station out of position.

Chromosomes occupy specific regions of the cell nucleus called chromosome territories. In somatic cells, scientists have observed that there is a correlation between this positioning and genome regulation. In fact, alterations in chromosome distribution have been related to certain diseases. Nevertheless, there are very few studies on chromosome territoriality in the cells that originate oocytes and spermatozoa (germ cells); cells that are subjected to a specific cell division process called meiosis.

A new study has found that gay and bisexual men are still earning less than heterosexual men despite legislation aimed at reducing discrimination in the workplace.

On May 22, about 170 ultramarathon racers were climbing an eight kilometer stretch of sand and gravel to a mountain top in Yellow River Stone Forest Park in northwest China. Suddenly, it seemed, the temperature dropped, the wind picked up, and the skies opened. Mostly dressed in shorts and t-shirts, armed with foil blankets, 29 runners were trapped, exposed to the weather elements. Twenty-one runners died and eight suffered injury, all from hypothermia. The tragedy sparked outrage in China: the weather was forecasted... Читать дальше...

A team of researchers, affiliated with UNIST has recently unveiled a hemolysis-free and highly efficient blood plasma separation platform. Published in the May 2021 issue of Small, this breakthrough has been led by Professor Joo H. Kang and his research team in the Department of Biomedical Engineering Department at UNIST. The research team expects that the new technology will greatly improve the accuracy of point-of-care blood tests, which has shown the increased demand recently.

A team of researchers from Italy, Spain and Georgia has found the remains of ancient hunting dogs at a dig site in what is now modern Georgia. In their paper published in the journal Scientific Reports, the group describes the fossils they found, their attempts to classify them and the possibility of the dogs interacting with early human ancestors.

James Meador, an independent researcher at the California Institute of Technology, has found evidence that suggests the Apollo 11 ascent stage may still be orbiting the moon. He has written a paper outlining his research and findings and has posted it on the arXiv preprint server.
