In the ongoing biodiversity crisis, large terrestrial animals are more threatened by extinction than any other group of organisms. The African continent holds an impressively intact large-mammal community, but there is still a lot we do not know about how these species evolved, became diverse and adapted to the changing climate and habitats. Many of these questions can be addressed by investigating the genomes and genetic variation across species. New research, published in Nature Communications, uses genomics to answer ...

(MEMPHIS, Tenn. – January 05, 2023) St. Jude Children’s Research Hospital investigators collaborated with a global group of acute pediatric critical illness experts to reach a consensus definition of the condition. Research on how to improve care in low- and middle-income countries has been stymied because conventional pediatric critical illness definitions are not applicable in these settings. The new, more universal definition, reached by consensus among researchers and clinicians from 40 countries, will enable scientists to study pediatric critical illness more universally, which should lead to improvements in patient outcomes ...

The past few years have seen Kenya, along with many other countries, confronted with multifaceted and compounding challenges.

Irvine, Calif., Jan. 8, 2024 — Additional staffing alone will not be sufficient to bridge the quality-of-care and health outcome disparities among nursing home facilities with varying percentages of residents with dementia, according to a first-of-its-kind study led by the University of California, Irvine. Specialized training, an easy-to-navigate environment and staff stability are also critical to meeting the unique challenges presented by this population.   The findings, recently published online in the journal Health Services Research, indicate that increased staffing generally improves outcomes for all patients but that at any given level of staffing, discrepancies ...

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study published in Current Biology. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development. In wild populations, infant survival is crucial for determining individual fitness and for maintaining viable populations in changing environments. For primates, ...

JACKSONVILLE, Florida — New research from Mayo Clinic suggests that artificial intelligence (AI) could improve the diagnosis of peripartum cardiomyopathy, a potentially life-threatening and treatable condition that weakens the heart muscle of women during pregnancy or in the months after giving birth. Researchers used an AI-enabled digital stethoscope that captures electrocardiogram (ECG) data and heart sounds to identify twice as many cases of peripartum cardiomyopathy ...

ITHACA, N.Y. – Whirligig beetles, the world’s fastest-swimming insect, achieve surprising speeds by employing a strategy shared by speedy marine mammals and waterfowl, according to a new Cornell University study that rewrites previous explanations of the physics involved. The centimeter-long beetles can reach a peak acceleration of 100 meters per second and a top velocity of 100 body lengths per second (or one meter per second). Not only do the results explain the whirligig’s Olympian speeds, but they also offer valuable insights for bio-inspired designers of near-surface water robots and uncrewed boats. Until ...

Sleep is a fundamental need, just like food or water. “You’ll die without it,” said Keith Hengen, an assistant professor of biology at Washington University in St. Louis. But what does sleep actually accomplish? For years, the best researchers could say is that sleep reduces sleepiness — hardly a satisfying explanation for a basic requirement of life. But by melding concepts from the fields of physics and biology, Hengen and a team of Arts & Sciences researchers have constructed a theory that could explain both the meaning of sleep and the complexity of the brain. As reported in a new study published ...

COLUMBUS, Ohio – New research shows that the recently emerged BA.2.86 omicron subvariant of the virus that causes COVID-19 can be neutralized by bivalent mRNA vaccine-induced antibodies in the blood, which explains why this variant did not cause a widespread surge as previously feared. However, the study in cell cultures showed this SARS-CoV-2 variant can infect human cells that line the lower lung and engage in virus-host cell membrane fusion more efficiently, two features linked to severe disease symptoms. The study is published today (Jan. 8, 2024) in the journal Cell. The BA.2.86 variant of omicron is the ancestor of the currently dominating JN.1 and has about ...

Led by Dr Phil Shaw from St Andrews and Dr Darcy Ogada of The Peregrine ...

After stem cell transplantation, the donated immune cells sometimes attack the patients' bodies. This is known as graft versus host disease or GvHD. Researchers at the Technical University of Munich (TUM) and the Universitätsklinikum Regensburg (UKR) have shown that GvHD is much less common when certain microbes are present in the gut. In the future, it may be possible to deliberately bring about this protective composition of the microbiome. Stem cell transplantation can save the lives of patients suffering ...
