More than a dozen bacterial species among the hundreds that live in people’s mouths have been linked to a collective 50% increased chance of developing head and neck squamous cell carcinoma (HNSCC), a new study shows. Some of these microbes had previously been shown to contribute to periodontal disease, serious gum infections that can eat away at the jawbone and the soft tissues that surround teeth. Experts have long observed that those with poor oral health are statistically more vulnerable than those with healthier ...

Sea robins are unusual animals with the body of a fish, wings of a bird, and walking legs of a crab. Now, researchers show that the legs of the sea robin aren’t just used for walking. In fact, they are bona fide sensory organs used to find buried prey while digging. This work appears in two studies published in the Cell Press journal Current Biology on September 26. “This is a fish that grew legs using the same genes that contribute to the development of our limbs and then repurposed these legs to find ...

Sea robins are ocean fish particularly suited to their bottom-dwelling lifestyle:  Six leg-like appendages make them so adept at scurrying, digging, and finding prey that other fish tend to hang out with them and pilfer their spoils. A chance encounter in 2019 with these strange, legged fish at Cape Cod’s Marine Biological Laboratory was enough to inspire Corey Allard to want to study them.   “We saw they had some sea robins in a tank, and they showed them to us, because they know we like weird animals,” said Allard, a ...

The number of days per year that are simultaneously extremely hot, dry, and have a high fire risk have as much as tripled since 1970 in some parts of South America. The results are published in a study in Communications Earth & Environment. South America is warming at a similar rate to the global average. However, some regions of the subcontinent are more at risk of the co-occurrence of multiple climate extremes. These compound extremes can have amplified impacts on ecosystems, economy, and human health. Raúl Cordero and colleagues calculated the number of days per year that each approximately 30 by 30 km grid ...

About The Study: This cross-sectional study found increased rates of both sudden unexpected infant death (SUID) and sudden infant death syndrome (SIDS) during the COVID-19 pandemic, with a significant shift in epidemiology from the pre-pandemic period noted in June to December 2021. These findings support the hypothesis that off-season resurgences in endemic infectious pathogens may be associated with SUID rates, with respiratory syncytial virus (RSV) rates in the U.S. closely approximating this shift. Further investigation into the role ...

About The Study: This study highlights the wide variation of nonprofit hospitals’ tax benefit across states, its high concentration among a small number of hospitals, and the primary role played by state and local taxes. Policy efforts to strengthen nonprofit hospitals’ taxpayer accountability are likely to be more effective when pursued at the local level.

Scientists at the National Institutes of Health (NIH) and their colleagues have identified a gene responsible for some inherited retinal diseases (IRDs), which are a group of disorders that damage the eye’s light-sensing retina and threatens vision. Though IRDs affect more than 2 million people worldwide, each individual disease is rare, complicating efforts to identify enough people to study and conduct clinical trials to develop treatment. The study’s findings published today in JAMA Ophthalmology. In a small study of six unrelated participants, researchers linked the gene UBAP1L to different forms of ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow development, called embryonic diapause, often happens at the blastocyst stage, just before the embryo implants in the uterus. During diapause, the embryo remains free-floating and pregnancy is extended. This dormant state can be maintained for weeks or months before development is resumed, when conditions are favorable. Although not all mammals use this reproductive ...

In both the natural world and human society, there commonly exist complex systems such as climate systems, ecological systems, and network systems. Due to the involvement of numerous interacting elements, complex systems can stay in multiple different states, and their overall behavior generally exhibits randomness and high disorder. For example, due to the complex interactions between factors such as solar radiation, terrain, and ocean currents, the climate system can exhibit various states like sunny, cloudy, and rainy. The dynamic changes and mutual influences of these factors make the behavior of the climate highly uncertain and difficult to predict accurately. For instance, the formation ...

Washington, September 26, 2024—The number of educational opportunities that children accrue at home, in early education and care, at school, in afterschool programs, and in their communities as they grow up are strongly linked to their educational attainment and earnings in early adulthood, according to new research. The results indicate that the large opportunity gaps between low- and high-income households from birth through the end of high school largely explain differences in educational and income achievement ...

The diverse biochemical composition of Japanese apricot fruits explains their broad spectrum of action on the human body. The high levels of key phenolic compounds and hydroxycinnamic acids contribute to various health benefits including anti-inflammatory, antioxidant, and antimicrobial properties. A recent study published in Food Research International on July 19, 2024, led by Prof. Yukiharu Ogawa and Jutalak Suwannachot from Chiba University, quantitatively evaluated the changes in phenolic compounds and antioxidant activity during the production of Shiso-zuke Umeboshi (PP). The study also simulated the digestive process to characterize the release of these compounds and ...

Parkinson’s disease (PD), the second most common neurodegenerative disorder globally, has long baffled scientists with its progressive nature and debilitating effects on motor function. A recent study from the School of Medicine at Fujita Health University has brought new insights into the metabolic disruptions experienced by patients with PD. By analyzing the blood and cerebrospinal fluid (CSF) of the patients, researchers have discovered critical impairments in purine metabolism and the recycling of adenosine triphosphate (ATP)—the molecule responsible for energy production in cells. For years, scientists have noted the decreased levels ...

Busy with work and other obligations, some people concentrate their moderate-to-vigorous exercise in one or two days of the week or weekend. A study led by investigators at Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system, has found that this “weekend warrior” pattern of exercise is associated with lower risk of developing 264 future diseases and was just as effective at decreasing risk as more evenly distributed exercise activity. Results are published in Circulation. “Physical activity is known to affect risk of many diseases,” said ...

Vaccination coverage for COVID-19 is high in both people with and without mental illness, according to a large multinational study led by researchers at Karolinska Institutet and published in Nature Communications. However, Swedish registry data revealed that individuals with unmedicated mental illness have lower vaccination levels. The researchers analysed data from seven studies in five countries (Sweden, Norway, Iceland, Estonia, and Scotland) as part of the COVIDMENT consortium, totalling just over 325,000 individuals, and registry data from Sweden including over ...

The discovery of an Earth-like planet 4,000 light years away in the Milky Way galaxy provides a preview of one possible fate for our planet billions of years in the future, when the sun has turned into a white dwarf, and a blasted and frozen Earth has migrated beyond the orbit of Mars. This distant planetary system, identified by University of California, Berkeley, astronomers after observations with the Keck 10-meter telescope in Hawaii, looks very similar to expectations for the sun-Earth system: it consists of a white dwarf about half the mass of the sun and an Earth-size companion in an orbit twice as large as Earth’s today. That is likely to be Earth’s fate. ...

Rockville, MD ̶ ̶ When a woman becomes pregnant, her iron requirements increase almost tenfold to support fetal development as well as her own increased iron needs.  Her ability to meet these increased iron needs depends on her iron stores at the beginning of the pregnancy as well as the physiological adaptations that enhance iron absorption as pregnancy progresses.  These physiological adaptations, however, are not always enough to support a pregnant woman’s iron needs, especially ...

Four out of five pregnant women in Ireland are iron deficient by their third trimester, a University College Cork (UCC) study reveals. Researchers at the Irish Centre for Maternal and Child Health (INFANT) and School of Food and Nutritional Sciences in UCC have shown that over 80% of women are iron deficient by their third trimester.    The findings raise concerns as the participants in the study were a low-risk and generally healthy cohort. Iron deficiency during pregnancy is linked to increased risks of complications for both mother and child, including neurodevelopmental challenges for the baby.   This study is the largest of its kind globally and was ...

Research at UMC Utrecht has identified 29 novel antibodies against the bacterium Klebsiella pneumoniae, an important cause of drug-resistant infections. Using genetic and functional approaches, the researchers also managed to unravel how these antibodies interact with antigens on the bacterial surface. Finally, they found that some of these novel antibodies act synergistically to neutralize this pathogen. The increasing problem of antimicrobial resistance (AMR) urgently calls for the development of alternative ...

Off the coast of Chile, in waters filled with krill and anchovy by the Humboldt Current system, live an elusive and little-known population of orcas. Thanks to citizen science and years of dedicated surveillance, a team of scientists led by Dr Ana García Cegarra of the Universidad de Antofagasta are unveiling their secrets — starting with dinner.   García Cegarra’s team, who previously observed these orcas using fishing boats to help them capture sea lions, have now spotted them successfully hunting dusky dolphins for the first time and sharing the food among the pod. This new evidence about their eating habits may help experts understand how populations ...

Amongst women who experience recurrent pregnancy loss, around 20% test positive for a specific antibody that targets the mother’s own body. A Kobe University-led research team now found a treatment that drastically increases these women’s chances of carrying to full-term without complications. Recurrent pregnancy loss is a condition of women who have lost two or more pregnancies for non-obvious reasons. The Kobe University obstetrician TANIMURA Kenji and his team have previously found that in 20% of these women, they can detect a specific antibody in ...
