Bones found at the site of an ancient fish-processing plant were used to genetically identify the species that went into a fish sauce, often known as garum, eaten throughout the Roman Empire
A multidisciplinary team of researchers, including archaeologists, have analyzed the DNA of fish remains from Roman fish fermentation vats, creating a method to identify animal remains when they are damaged beyond recognition.
Mothers who choose to work from home regularly earn about 10% more than those who do not, but fathers get no significant benefit, a major new study says.
Traditional medical tests often require clinical samples to be sent off-site for analysis in a time-intensive and expensive process. Point-of-care diagnostics are instead low-cost, easy-to-use, and rapid tests performed at the site of patient care. Recently, researchers at the

A University of California, Riverside-led team has made an advance in the basic understanding of Plasmodium falciparum, the parasite responsible for the deadliest form of human malaria, that could make novel, highly targeted anti-malarial therapies possible.
Archaeologists have long thought that monumental architecture—large, human-built structures that emphasize visibility—were products of societies with power structures, including social hierarchy, inequality and controlled labor forces. But this notion is being questioned as
Developing countries pay less for the nutrition in seafood imports than developed countries, largely because developed countries pay a premium for non-nutritional attributes such as convenience, according to an economic analysis published in Nature Communications on July 1. The
An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in the U.S. and taking the world by surprise.
It is possible to make a material absorb more radiation than it has to re-emit, violating the laws of physics in a way that could make energy-harvesting devices more efficient

What can a tiny wasp with a rather gruesome parasitic life cycle teach us about evolution, behavior and human developmental diseases? In a new paper, researchers led by István Mikó and Holly Hoag at the University of New Hampshire (UNH) suggest that it may be a lot.
For a decade, scientists have believed that plants sense temperature mainly through specialized proteins, and mainly at night when the air is cool. New research suggests that during the day, another signal takes over. Sugar, produced in sunlight, helps plants detect heat and
By combining artificial intelligence with automated robotics and synthetic biology, researchers at the University of Illinois Urbana-Champaign have dramatically improved the performance of two important industrial enzymes—and created a user-friendly, fast process to improve
A new study published in the Strategic Entrepreneurship Journal examines how long-standing cultural practices, specifically cousin marriage traditions, continue to influence business outcomes in sub-Saharan Africa's informal economy.
Proteins have specific biological functions in cells through conformational changes and interactions. Therefore, precise, in situ analysis of protein complex changes is essential for understanding cellular functions, uncovering disease mechanisms, and identifying potential drug
Operators lost contact with the MethaneSAT satellite on 20 June, a significant blow to efforts to track – and stop – methane emissions
Age is just a number, or is it? A new study by UTEP researchers shows that adult moths are more vulnerable to attack than when they are young.
In the course of a collaboration with the University of Baghdad, LMU's Enrique Jiménez has rediscovered a text that had been lost for a thousand years. A paper on this discovery is published in the journal Iraq.
Cornell researchers have found a new and potentially more accurate way to see what proteins are doing inside living cells—using the cells' own components as built-in sensors.
A new study led by Michigan State University provides insights into the personality perceptions surrounding tattooed individuals. As tattoos become more mainstream, this research sheds light on how specific tattoos are judged—and shows how wrong those judgments can be.
Plant scientists have used a standard "gene gun" since 1988 to genetically modify crops for better yield, nutrition, pest resistance and other valuable traits.
A team of scientists across several U.S. Department of Energy (DOE) national laboratories has unraveled how light and a previously unknown form of certain nickel-based catalysts together unlock and preserve reactivity. This research, described in the journal Nature
Using an inexpensive electrode coated with DNA, MIT researchers have designed disposable diagnostics that could be adapted to detect a variety of diseases, including cancer or infectious diseases such as influenza and HIV.
A national study published in Environmental Science & Technology finds that children aged 2 to 4 years in the United States are routinely exposed to a broad range of potentially harmful chemicals. Many of the chemicals the researchers identified are not routinely monitored and
Many single-use plastic products have been banned in the EU since July 3, 2021, so they can no longer be produced or marketed. However, more eco-friendly reusable solutions are not a feasible alternative for all areas of application. There is a lack of solutions for functional,
A new result from the molecular gas survey in the Southern Pinwheel Galaxy M83 using the Atacama Large Millimeter/submillimeter Array (ALMA) Telescope reveals a discovery of 10 high-velocity clouds composed of molecular gas, moving at velocities significantly different from
Scientists have studied a new target for antibiotics in the greatest detail yet—in the fight against antibiotic resistance. The "molecular machine" flagellum is essential for bacteria to cause infection, allowing bacteria to "swim" around the bloodstream until finding something
While the current generation of artificial intelligence chatbots still flub basic facts, the systems answer with such confidence that they're often more persuasive than humans. Adults, even those such as lawyers with deep domain knowledge, still regularly fall for this. But
In their paper published in Science of the Total Environment, researchers from IIASA and Lviv Polytechnic National University in Ukraine presented a novel approach to measure and understand human pressure on planet Earth. The researchers explored how carbon emissions can be
Prostate cancer is one of the most common malignancies in men globally. Hormonal therapies targeting the androgen–androgen receptor axis have significantly delayed disease progression. However, drug resistance remains inevitable, and new therapeutic targets and strategies are
Cities around the world pursue urban renewal under the banner of resilience and diversity. The idea is simple: if neighborhoods include socially and economically diverse residents, it will lead to stronger social cohesion, greater trust, and mutual support among the community.
A study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished—doubling in numbers and growing larger. This unprecedented
Managers who have knowledge, a clear mandate, and experience with alcohol-related issues report that they more frequently introduce preventive measures at work. This is shown by a survey conducted by the University of Gothenburg.
Wheat contains many valuable nutrients—and can help to make a diet with bread even healthier. However, the nutrient content depends on the type of wheat. A rapid test method could help to increase the nutrient content of wheat along the entire value chain.
A striking, silver-colored fish commonly kept as an aquarium pet has been hiding in plain sight in the Philippines' largest freshwater lake, renewing concerns over the unmonitored and unmitigated release of alien species into the country's already strained ecosystems.
A joint team led by researchers from the University of New South Wales has revealed the alarming impact of heat waves on pet dogs.

With burgers sizzling and classic rock thumping, many Americans revel in summer cookouts—at least until that wayward cousin asks for a "pop" in soda country, or even worse, a "coke" when they actually want a Sprite.
Even at 90 years old, Ronald P. Rohner still works 365 days a year.
