URBANA, Ill. – Early childhood is an important time for learning about nutrition and establishing healthy eating behaviors. Young children rely on parents to provide food options, and the availability of food in the home affects their dietary choices. A new study from the University of Illinois Urbana-Champaign looks at changes in home food availability and nutrient intake for children from 2 to 4 years old. “It's important to understand how the environments that children are in can influence their diet and nutrition. What types of foods and beverages are available in the home, and how accessible ...

Cell division is the generative spark of nearly every lifeform on Earth. But if healthy growth goes unchecked, cell division can turn lethal, overwhelming the organism. Such is the case with so-called oncogenes. When altered by a mutation, these growth-moderating genes go haywire, producing a geyser of cancer cells as a result. Oncogenes are also insidiously adept at generating tumors that over time become genetically “independent” from their origin, so it has been exceedingly difficult for scientists to shut down their replication ...

Sparks fly when a female nematode meets her mate in a Petri dish. Tracking him by smell, she beelines over and is pregnant within moments of physical contact. But for the hermaphroditic version of these tiny roundworms, it’s a very different story. Anatomically female but capable of self-fertilizing with their own supply of sperm, hermaphrodites remain emphatically uninterested in mating—until their sperm supply runs dry. Only then will they seek out males.  Within such previously unknown details about microscopic mating rituals ...

NEWPORT NEWS, VA – Superconducting radiofrequency (SRF) technology allows particle accelerators to efficiently produce powerful electron beams. Physicists use these beams to study the building blocks of matter at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility. But these research machines also have a promising list of industrial applications. Now, some researchers are figuring out how to get SRF accelerators out of the lab and into industry. One potential industrial use is in water treatment plants. Per- and polyfluoroalkyl substances (PFAS) are present in many products, including certain non-stick cookware, water-resistant ...

Mounting evidence suggests that FDA-approved weight loss medications, such as Wegovy, not only help patients lose weight but also protect against complications from obesity such as cardiovascular disease. In 2021, 40 percent of patients enrolled in Medicaid had obesity. The high cost of these drugs has raised concerns about affordability, both for patients and public insurance programs.   Researchers from Brigham and Women’s Hospital, a founding member of Mass General Brigham, studied state Medicaid coverage policies for anti-obesity medications from 2011 through the first quarter of 2023, finding that 10 out of 47 states covered at least ...

PHILADELPHIA – Antibody responses to new SARS-CoV-2 variant infections and vaccinations are powerfully shaped by prior exposures to earlier SARS-CoV-2 vaccines, according to a new study from the Perelman School of Medicine at the University of Pennsylvania. In the study, published today in Immunity, the researchers analyzed antibody responses in people infected with or vaccinated against the relatively new SARS-CoV-2 variants BA.5 and XBB. They found that even though BA.5 and XBB are very different from the original “ancestral” ...

DURHAM, N.H.—Television dramas, like CSI and NCIS, make criminal investigations look easy. In real life, DNA testing can be challenging and requires expensive equipment, special facilities and extensive training to identify DNA from a crime scene and determine which belongs to a potential suspect and which may have been transferred from someone who was never there. Research from the University of New Hampshire has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and ...

With the help of the ESRF, researchers from Karolinska Institutet (Sweden) have discovered the reproductive mechanism that permanently blocks polyspermy — a pathologic condition that arises when more than one sperm fuses with the egg, and which is lethal for embryo development. They also revealed the atomic architecture of the egg coat, which explains a set of genetic mutations causing infertility and it could make an impact in the development of non-hormonal contraception. The results are out in the journal Cell. Infertility ...

Increasing sea surface temperatures over the past 20 years in Mobile Bay — an estuary in the US state of Alabama — have coincided with five-fold increases in the abundance of juvenile bull sharks (Carcharhinus leucas), according to a study published in Scientific Reports. Bull sharks are found globally in warm, shallow coastal waters in both fresh and saltwater environments. They help balance and maintain the health of coastal ecosystems by regulating prey populations. Along with great white shark (Carcharodon carcharias) and tiger shark (Galeocerdo cuvier), they are among the shark species that are most like to negatively interact with humans. Lindsay ...

LOS ANGELES — A clinical trial from Keck Medicine of USC aims to provide a surgical solution for patients with a form of advanced pancreatic cancer previously considered inoperable.   The study will investigate if chemotherapy followed by a novel type of surgery to remove the cancer is a safe and effective option for patients with locally advanced pancreatic cancer, meaning that the cancer has not spread to other organs, but has grown into or close to nearby blood vessels that surround the pancreas.  “Usually, these types of tumors cannot be ...

Advanced killer robots are more likely to blamed for civilian deaths than military machines, new research has revealed. The University of Essex study shows that high-tech bots will be held more responsible for fatalities in identical incidents. Led by the Department of Psychology’s Dr Rael Dawtry it highlights the impact of autonomy and agency. And showed people perceive robots to be more culpable if described in a more advanced way.

Contrary to common belief, not all vertebrates regulate their sleep-wake rhythm in the same way. University of Basel researchers have discovered that some fish – unlike humans – do not need orexin to stay awake. This molecule was thought to be necessary for normal wake and sleep rhythms in vertebrates. Humans without orexin suffer from narcolepsy. Until recently, it was assumed that vertebrates share similar mechanisms controlling sleep behavior. That's why researchers have been using fish in the past 20 years as a model organism to study sleep ...

After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo. This is according to a new study led by researchers at Karolinska Institutet and published in the journal Cell. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods. Fertilization in mammals begins when a sperm attaches to the egg coat, a filamentous extracellular envelope that sperm must penetrate ...
