CNN — The discovery of 330 stone artifacts in Kenya that date back 2.9 million years is throwing light on a key question in human evolution — who first used…
The atmospheric level of carbon dioxide — a gas that is great at trapping heat, contributing to climate change — is almost double what it was prior to the Industrial Revolution, yet it only constitutes 0.0415% of the air we breathe. This presents a challenge to researchers attempting to design…
The brain floats in a sea of fluid that cushions it against injury, supplies it with nutrients and carries away waste. Disruptions to the normal ebb and flow of the fluid have been linked to neurological conditions including Alzheimer’s disease and hydrocephalus, a disorder involving excess fluid around the brain.…
Lithium-ion batteries have transformed everyday lives — almost everyone has a smartphone, more electric vehicles can be spotted on the roads, and they keep power generators going during emergencies. As more portable electronic devices, electric vehicles and large-scale grid implementations come online, the demand for higher energy density batteries that…
Astronomers have barely scratched the surface of mapping the nearly endless stars and galaxies of the heavens. Using supercomputers, researchers with The University of Texas at Austin have has now revealed the locations of more than 200,000 new astronomical objects. Their goal is to map even more and use that…
A single oral dose of the antibiotic azithromycin can reduce the risk of postpartum sepsis and death among women who deliver vaginally by one-third, according to a large multi-country clinical trial funded by the National Institutes of Health. Only 1.6% of women in the study who received azithromycin during labor…
Along the shores of Africa’s Lake Victoria in Kenya roughly 2.9 million years ago, early human ancestors used some of the oldest stone tools ever found to butcher hippos and pound plant material, according to new research led by scientists with the Smithsonian’s National Museum of Natural History and Queens…
CNN — The organizers of the European Super League (ESL) have unveiled a revamped competition with “60 to 80 teams,” they announced in a statement on Thursday. The ESL was set up in 2021 by 12 European clubs with the intention to break away from European football’s governing body UEFA…
Washington CNN — Congress is receiving new evidence Thursday of internal chaos at Southwest Airlines over the Christmas holiday meltdown. The Senate Commerce committee is questioning Southwest executive Andrew Watterson, alongside Southwest pilot union president Casey Murray, Sharon Pinkerton of the Airlines for America trade group, Paul Hudson of Flyers’…

This image provided by the U.S. Navy sailors assigned to Explosive Ordnance Disposal Group 2 recover a high-altitude surveillance balloon off the coast of Myrtle Beach, South Carolina of February 5. (US Navy via AP) The FBI investigation into the suspected Chinese spy balloon recovered in the Atlantic Ocean is…
CNN — The president of SpaceX revealed the company has taken active steps to prevent Ukrainian forces from using the critical Starlink satellite technology with Ukrainian drones that are a key component of their fight against Russia. “There are things that we can do to limit their ability to do…
Our roads might one day be safer thanks to a completely new type of system that overcomes some of lidar’s limitations. Lidar, which uses pulsed lasers to map objects and scenes, helps autonomous robots, vehicles and drones to navigate their environment. The new system represents the first time that the…
Why do some people get ADHD, while others do not? And how early in life or in the womb is the seed of ADHD sown? Researchers from Aarhus University have come closer to answering this question in a large study, which has just been published in the journal Nature Genetics.…
In a first of its kind randomized controlled trial an international team of researchers led by the Butler Columbia Aging Center at the Columbia University Mailman School of Public Health shows that caloric restriction can slow the pace of aging in healthy adults. The CALERIE™ intervention slowed pace of aging…
Researchers have calculated the carbon footprint for the full life cycle of fertilisers, which are responsible for approximately five percent of total greenhouse gas emissions — the first time this has been accurately quantified — and found that carbon emissions could be reduced to one-fifth of current levels by 2050.…
When cells copy DNA to produce RNA transcripts, they include only some chunks of genetic material known as exons and throw out the rest. The resulting product is a fully-mature RNA molecule, which can be used as a template to build a protein. One of the features of gene expression…
In a new Nature Energy paper, engineers report progress toward lithium-metal batteries that charge fast — as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown — quickly and uniformly — on a surprising surface. The trick is to use…
A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex for classical computers, the same quantum mechanics also imparts a minimum level of unavoidable error that…
CNN — The agent of Ghanaian soccer star Christian Atsu says the player’s whereabouts are still not known, reversing course just a few days after telling CNN Sport that the Hatayspor winger was rescued from rubble after being caught in the earthquakes that struck southern Turkey. “I am currently in…
Kyiv, Ukraine CNN — Private military contractor Wagner will have to look for new fighters beyond Russia’s prison system, a fertile recruiting ground for the past nine months, according to its boss Yevgeny Prigozhin. Prigozhin said on his company’s Telegram channel Thursday: “We have completely discontinued the recruitment of prisoners…
CNN — For the second time in around a week, a New Jersey council member was found shot dead. Councilman Russell Heller, 51, was in his car in the parking lot of the PSE&G facility in Somerset County when a former worker approached his car and shot him, according to…
New images of Saturn from NASA’s Hubble Space Telescope herald the start of the planet’s “spoke season” surrounding its equinox, when enigmatic features appear across its rings. The cause of the spokes, as well as their seasonal variability, has yet to be fully explained by planetary scientists. Like Earth, Saturn…
If watching animals feast on human blood for 30-plus hours isn’t your idea of fun, don’t worry. The robot can do it. Rice University bioengineers have teamed up with tropical medicine experts from Tulane University to take some of the pain out of studying the feeding behavior of mosquitoes. The…
The rumour that the coastal cod is extinct is not true. Through DNA analyses, researchers at the University of Gothenburg have identified that there are still juvenile coastal cod off the west coast of Sweden. However, it is still difficult to find any mature adult cod in the area. By…
Even though students’ grades are no worse with online teaching than with face-to-face teaching, many report that the learning process is not sufficient. In 2022, researchers from Ruhr University Bochum’s Faculty of Medicine proved that the body actually reacts differently to online teaching than to face-to-face formats, specifically with a…
DNA can help to stimulate bone healing in a localised and targeted manner, for example after a complicated fracture or after severe tissue loss following surgery. This has been demonstrated by researchers at Martin Luther University Halle-Wittenberg (MLU), the University of Leipzig, the University of Aveiro (Portugal) and the Fraunhofer…
Antiferroelectric materials have electrical properties that make them advantageous for use in high-density energy storage applications. Researchers have now discovered a size threshold beyond which antiferroelectrics lose those properties, becoming ferroelectric. “Electronic devices are getting smaller and smaller, which makes it increasingly important for us to understand how a material’s…
Players and coaches for the Philadelphia Eagles and Kansas City Chiefs will spend hours and hours in film rooms this week in preparation for the Super Bowl. They’ll study positions, plays and formations, trying to pinpoint what opponent tendencies they can exploit while looking to their own film to shore…
Climate change is a global environmental concern. A major contribution to climate change comes from excessive burning of fossil fuels. They produce carbon dioxide (CO2), a greenhouse gas responsible for global warming. In this light, governments globally are framing policies to curb such carbon emissions. However, merely curbing carbon emissions…
