Like forensic investigators, scientists can use molecular techniques to detect evidence of Antarctic krill in seawater samples collected in the Southern Ocean. The revolutionary technology can identify Antarctic krill DNA within the alphabet soup of DNA molecules shed by numerous other marine creatures, including bacteria, other krill species, and whales.

The year 2022 was a remarkable and historic time for the employment of people with disabilities. That’s according to the National Trends in Disability Employment (nTIDE) 2022 Year-End Special Edition, issued by Kessler Foundation and the University of New Hampshire’s Institute on Disability (UNH-IOD), based on data from the U.S. Bureau of Labor Statistics (BLS) Jobs Reports.

With widespread La Niña flooding in the Murray-Darling Basin, common carp (Cyprinus carpio) populations are having a boom year. Videos of writhing masses of both adult and young fish illustrate that all is not well in our rivers. Carp now account for up to 90% of live fish mass in some rivers.

Solar flares and other types of space weather can wreak havoc with spaceflight and with telecommunications and other types of satellites orbiting Earth. But to date, scientists’ ability to research ways to overcome that challenge has been severely limited. That’s because experiments they conduct in laboratories here on Earth are affected by gravity in ways that are quite different from conditions in space. Read Full Article Here source: Phys.org

Honeybees, which pollinate one-third of the crops Americans eat, face many threats, including infectious diseases. On Jan. 4, 2023, a Georgia biotechnology company called Dalan Animal Health announced that it had received a conditional license from the U.S. Department of Agriculture for a vaccine designed to protect honeybees against American foulbrood, a highly destructive infection.

Kenya’s last execution of a prisoner was in 1987. But the country still hosts a death row population of nearly 600. Almost all were sentenced to death for murder or robbery with violence. New sentences are handed down every year. Read Full Article Here source: Phys.org

Idalia Fedotova, researcher at HSE University and the RAS Ivannikov Institute for System Programming, examined lexical differences across Khanty dialects and found that members of this relatively small ethnic group speak three distinct languages—rather than two, as previously thought. The findings are published in Ural-Altaic Studies. Read Full Article Here source: Phys.org

A team of researchers at Université de Lorraine in France, working with a colleague from Brock University in Canada, and one each from Université Clermont Auvergne and Université Lyon, both in France, has found evidence of large deposits of plagioclase feldspar in the walls of Valles Marineris on Mars. In their study, published in the journal Geophysical Research Letters, the group used data from the Mars Reconnaissance Orbiter (MRO) to find the igneous rock and determine what the find might reveal about the history of the planet.

A study published in The ISME Journal identified 522 genomes of archaea and bacteria associated with the roots and soil of two plant species native to the Brazilian montane savanna ecoregion known as campos rupestres (“rocky meadows”). Hundreds of microorganisms hitherto unknown to science were identified, showing that the ecoregion is a biodiversity hotspot and that many new organisms have yet to be described and classified in Brazil.

Heavy metals such as lead and cadmium are present in batteries, cosmetics, food and other things that are part of everyday life. They are toxic when they accumulate in the human organism, potentially causing several health problems, but detecting them in body fluids requires expensive equipment and a controlled laboratory environment. Researchers at the University of São Paulo (USP) in Brazil have now developed a portable sensor made of simple materials to detect heavy metals in sweat, which is easily sampled.

In France, MPs have recently considered whether to reintroduce compulsory school uniform, with first lady Brigitte Macron adding her support to the idea. “It erases differences, it saves time,” she said. These perceptions of the benefits of uniform are widely held—but do they hold up? Read Full Article Here source: Phys.org

Shrimps, flies and other animals shed their outer body covering at specific times of the year or at specific points in their life cycles through a process called molting. Working with worms, FMI researchers identified the mechanisms underlying a molecular “molting clock”—as well as several of the clock’s components. The findings may help to throw light on skin development and regeneration in other animals, including mammals. Read Full Article Here

A newly-published hypothesis, led by a UCL researcher, suggests a momentary leap in a single species on a single day millions of years ago might ultimately have led to the arrival of mammals—and therefore humans. Read Full Article Here source: Phys.org

The EU regularly exports large quantities of poultry meat to West African countries. These exports have been criticized for harming importing countries in West Africa and exacerbating poverty there. The reason: Cheap imports depress the local price of chicken, making life difficult for local smallholders. Read Full Article Here source: Phys.org

Seneca, the Roman stoic philosopher, wrote that “luck does not exist.” Modern managerial studies take the liberty of disagreeing. Luck exists in the form of events that are beyond the control of CEOs and firms alike. Movements in oil prices and the business cycle (e.g., variations in GDP growth, and employment rate) that boost the market value of firms are a couple of examples.
