It might be humbling to consider, but cockroaches and people have more in common than we knew. Biologists at the University of Cincinnati discovered that some cockroaches, like people, need more sleep when they’re pregnant. And baby cockroaches need the mom to sleep longer for proper development. The study was published in the Journal of Experimental Biology. “A lot of us take adequate sleep for granted because we don’t usually experience an immediate adverse effect of sleep deprivation,” said study co-author Oluwaseun Ajayi, a postdoctoral researcher in UC’s College of Arts and Sciences. “The truth is the health consequences ...

As companies increasingly compete on the basis of technology, brand, and knowledge, a new study reveals that the effectiveness of corporate boards plays a critical role in maximizing the value of intangible assets—especially during international expansion through acquisitions. In a study recently published in the Global Strategy Journal, researchers Xavier Martin (Tilburg University) and Tao Han (emlyon business school) analyzed 675 cross-border acquisitions by U.S. public firms to understand how intangible assets contribute to firm value abroad—and under what conditions. Their findings are clear: while firms with high R&D and advertising intensity ...

Stress internalization is a significant risk factor for age-related cognitive decline in older Chinese Americans, according to Rutgers Health researchers.   The study, published in The Journal of Prevention of Alzheimer’s Disease by researchers from the Rutgers Institute for Health, Health Care Policy and Aging Research, examined multiple risk and resilience factors associated with cognitive decline in Chinese adults older than 60.   Researchers chose to study this population because older Chinese Americans are historically underrepresented ...

Primates - the group of animals that includes monkeys, apes and humans - first evolved in cold, seasonal climates around 66 million years ago, not in the warm tropical forests scientists previously believed.  Researchers from the University of Reading used statistical modelling and fossil data to reconstruct ancient environments and trace where the common ancestors of all modern primates lived.   The study, published today (Tuesday, 5 August) in the journal PNAS, says these first primates most likely lived in North America in a cold climate with hot summers and freezing winters, overturning the long-held "warm tropical ...

It’s known as biology’s central dogma: All living organisms’ genetic information is stored in DNA, which is transcribed into RNA, which is translated into proteins that perform nearly all essential tasks in a cell. A tiny cellular machine called the ribosome builds a protein until it’s signaled to stop, and the protein is released into the cell through a reaction with a water molecule. But scientists have long puzzled over one detail: If all it takes is a water molecule to release the finished protein, why doesn’t it happen by accident? Now researchers ...

For a wide variety of earthquake scenarios in Alaska, an earthquake early warning (EEW) system could provide at least 10 seconds of warning time for hazardous shaking, according to a new report. Increasing the density and improving the spacing of seismic stations around the state could add 5 to 15 seconds to these estimated warning times, write Alexander Fozkos and Michael West at the University of Alaska Fairbanks. Alaska experiences tens of thousands of earthquakes each year, and has been the site some of the world’s largest and most destructive seismic events. The study’s findings published in the Bulletin of the Seismological Society of America could help ...

Young chimpanzees learn their communication style from their mother and maternal relatives, but show little similarity to the communication behavior of their father and paternal relatives, according to a study publishing August 5th in the open-access journal PLOS Biology by Joseph Mine at the University of Zurich, Switzerland, and colleagues. Human children learn how to communicate as they develop, and their communication behavior is heavily influenced by their main caregivers. Although chimpanzees also communicate ...

A new study finds that kids with obesity are more likely to have obese parents because they inherit obesity-related genes, and to a smaller extent, are impacted indirectly by genes carried by the mother – even when those genes aren’t passed down. A new study led by Liam Wright of the University College London, UK, and colleagues, reports these findings August 5th in the open-access journal PLOS Genetics. Studies commonly show that children with obesity often have parents with obesity, but the cause of this trend has been poorly understood. ...

A mother’s genetics may play a bigger role in determining whether a child becomes overweight than a father’s, as a result of a concept known as genetic nurture, finds a new study led by UCL researchers. Published in PLOS Genetics, the study analysed genetic and health data from 2,621 UK families in the Millennium Cohort Study, a UK birth cohort study of individuals born in 2001/02.  Researchers investigated how parents’ body mass index (BMI) and related genes influence their children’s weight and diet from birth to age 17. To do this, the team examined the association between parental BMI and ...

As use of the popular anti-diabetic and weight-loss drug Ozempic skyrockets, so have concerns about the medication’s side effects. One such side effect is loss of “lean mass”—body weight that isn’t fat—raising concerns that Ozempic could be reducing muscle mass and strength. New research in mice suggests that muscle mass changes less than expected, but muscles may still get weaker, pointing out an urgent need for clinical studies to pin down the full effects of the popular medications. “If we want to really help the individuals ...

A critical water source for vast areas of the Northern Territory is drying at an accelerating rate, according to new findings, with losses clearly visible from space. The Cambrian Limestone Aquifer (CLA) is a large, interconnected limestone system containing high-quality groundwater that supports numerous NT rivers, towns, Indigenous communities, pastoral enterprises, and irrigated agriculture. But the findings, published in a new study led by Griffith University researchers, show the aquifer has experienced significant water loss since 2014, reaching its lowest recorded storage level in 2021 (the end of the study period). The study draws on two decades ...

What looks like a microscopic dance battle is actually a life-or-death strategy. In scalding hot water rushing through narrow channels, some bacteria have evolved a surprising survival technique: they cling to surfaces, stand upright, and sway rhythmically—like tiny street dancers fighting the flow. Watch the video of the bacterial “reverse-flow dance”: https://youtu.be/JDN28g-aE78 This dramatic behavior was captured for the first time on video by a team led by Dr. Daisuke Nakane, Associate Professor at the University of Electro-Communications in Tokyo, in collaboration with Professors Masatada Tamakoshi and Ryota Morikawa at ...

A groundbreaking study has provided new insights into the forces that cause tectonic movements in Europe’s most seismically active regions. Researchers used advanced satellite data to track land movements in Greece, western Turkey and the southern Balkan countries. “This is crucial information for assessing the risk of major earthquakes.” Friction Tectonic plates diverge, converge, or move past each other in opposing directions at speeds of 0.1 to 90 millimetres per year. At many plate boundaries, rocks on both sides of the fault remain stuck for decades or centuries while the plates continue to move. This causes material stress ...

The Great Barrier Reef has experienced the largest annual decline in coral cover in two of the three regions since AIMS began monitoring 39 years ago. This was predominantly driven by climate change-induced heat stress leading to coral mortality from the 2024 mass bleaching event, but also by the impacts of cyclones and crown-of-thorns starfish outbreaks. Coral cover dropped over the year: in the northern region (Cape York to Cooktown) by a quarter (from 39.8% to 30%) in the central region (Cooktown to Proserpine) by 13.9% ...

Wastewater often contains a cocktail of organic pollutants, ranging from pesticides to pharmaceutical residues. These are difficult to remove using conventional purification methods. However, a recent doctoral thesis from the Norwegian University of Science and Technology (NTNU) presents a creative method to get rid of them. “We can break down the harmful chemicals in the water using sunlight and small droplets of oil,” said NTNU’s Zygimantas Gricius. “Gricius and his colleagues have studied the purification of industrial wastewater. They looked at the breakdown of naphthenic acids, which can be found in wastewater from ...

We usually think of satellites as small objects orbiting planets or stars. But in the broader universe, galaxies themselves can have satellites—smaller galaxies bound by gravity that orbit a larger host, carrying with them stars, gas, dust, and dark matter. Most of what we know about satellite galaxies comes from studying the Milky Way and other similarly large galaxies. But a new study led by Dartmouth astronomers broadens that understanding by exploring the satellites of dwarf galaxies—systems less than a tenth the size of the Milky Way. The multi-institutional survey triples the number of dwarf ...
