ITHACA, N.Y. – Ecologists have demonstrated that the genetic material that species shed into their environments can reveal not only the presence of the species but also a broad range of information about the genetics of whole populations — information that can help scientists trace the source of a new invasive population as well as prevent further invasion. The advancement in environmental DNA (eDNA) also opens new possibilities for protecting endangered and vulnerable species. “For the benefit of biodiversity conservation, we’re ...

During the Later Stone Age in what is now Namibia, rock artists imbued so much detail into their engravings of human and animal prints that current-day Indigenous trackers could identify which animals’ prints they were depicting, as well as the animals’ general age and sex. Andreas Pastoors of Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany, and colleagues report these findings in a new study published September 13 in the open-access journal PLOS ONE. Engravings of animal tracks and human footprints appear in numerous ...

People who use both tobacco and cannabis are more likely to report anxiety and depression than those who used tobacco only or those who used neither substance, according to a new study published this week in the open-access journal PLOS ONE by Nhung Nguyen of the University of California, San Francisco, USA, and colleagues. Tobacco and cannabis are among the most commonly used substances worldwide, and their co-use has been on the rise amid the expanding legalization of cannabis. In the new study, the researchers analyzed data on the substance use and mental health of 53,843 US adults who participated in online surveys as part of the COVID-19 Citizens Health Study, which ...

Researchers at the University of Washington have developed small robotic devices that can change how they move through the air by "snapping" into a folded position during their descent. When these "microfliers" are dropped from a drone, they use a Miura-ori origami fold to switch from tumbling and dispersing outward through the air to dropping straight to the ground. To spread out the fliers, the researchers control the timing of each device's transition using a few methods: an onboard pressure ...

In a survey of cat owners, those who fed their cats vegan diets tended to report better health outcomes for their pets than those who provided meat-based diets, though the differences were not statistically significant. Andrew Knight of the University of Winchester, UK, and colleagues present these findings in the open-access journal PLOS ONE on September 13. Many pet foods contain cooked meat as the primary protein source, but a growing number of available products use alternative protein sources, such as plants or fungi. Some veterinary professionals ...

In a study involving several wolves and dogs, both animals performed better at finding hidden food if they had observed the food being hidden by a person—suggesting that they remembered where the food was, and did not rely solely on scent to find it. Sebastian Vetter of the University of Veterinary Medicine Vienna, Austria, and colleagues present these findings in the open-access journal PLOS ONE on September 13. Many species transmit important information through social learning, where one individual learns by observing ...

A new study updates the planetary boundary framework and shows human activities are increasingly impacting the planet and, thereby, increasing the risk of triggering dramatic changes in overall Earth conditions. For over 3 billion years, the interaction between life (represented by the planetary boundary, Biosphere Integrity) and climate have controlled the overall environmental conditions on Earth. Human activities, for example replacing nature with other land uses, changing the amount of water in rivers and in soil, the introduction of synthetic chemicals to the open environment, and the emission of greenhouse gases to the atmosphere ...

Professor Christian Ottensmeier, and Professor Natalia Savelyeva from the Institute of Systems, Molecular and Integrative Biology are collaborating with industry partner Genomics England and working closely with Touchlight Genetics Ltd to develop a vaccine therapy for patients with non-small cell lung cancer who have not had sufficient benefit from standard immunotherapy. Non-small ...

A new study finds that a natural compound found in many plants inhibits the growth of drug-resistant Candida fungi — including its most virulent species, Candida auris, an emerging global health threat. The journal ACS Infectious Diseases published the discovery led by scientists at Emory University. Laboratory-dish experiments showed that the natural compound, a water-soluble tannin known as PGG, blocks 90% of the growth in four different species of Candida fungi. The researchers also discovered how PGG inhibits the growth: It grabs up iron molecules, essentially starving the fungi of an essential nutrient.   By starving the fungi rather than attacking ...

The vertebral bones that form the spine are derived from a distinct type of stem cell that secretes a protein favoring tumor metastases, according to a study led by researchers at Weill Cornell Medicine. The discovery opens up a new line of research on spinal disorders, helps explain why solid tumors so often spread to the spine, and could lead to new orthopedic and cancer treatments. In the study, published Sept. 13 in Nature, the researchers discovered that vertebral bone is derived from ...

“This study provides evidence that supports the belief of researchers and advocates that national policies protecting the human rights of lesbian, gay and bisexual people have an impact on individual development,” University of Delaware Assistant Professor Eric K. Layland said. “For LGB people, many of these identity and social milestones occur during the critical developmental period of adolescence. Results of this study add to other research showing protective policy can benefit LGB health by ...

Unruptured cerebral aneurysms of sizes and locations that require attention may be frequently missed in routine clinical care, but a machine learning algorithm could minimize missed care opportunities, according to a new study from UTHealth Houston.

Sheth, MD, associate professor in the Department of Neurology with McGovern Medical School at UTHealth Houston, as well as co-first authors Hyun Woo Kim, MD, vascular and interventional neurology fellow at UTHealth Houston, and ...

If the Chicago region replaced 30% of all on-road combustion-engine vehicles — including motorcycles, passenger cars and trucks, buses, refuse trucks and short- and long-haul trucks — with electric versions, it would annually save more than 1,000 lives and over $10 billion, according to a new Northwestern University study. The new study, which simulates air quality at a neighborhood scale, also found that areas with predominantly Black, Hispanic and Latinx residents would benefit most. The study underscores the potential of electric vehicles (EVs) to improve ...

Philadelphia, September 13, 2023 – There is already robust evidence that people living with cardiovascular disease are disproportionately affected by poor air quality and extreme temperatures, in large part due to climate change, the greatest threat to human health of the 21st century. In this special theme issue of the Canadian Journal of Cardiology, published by Elsevier, noted experts comprehensively review how climate change occurs and increases the risk of cardiovascular disease and provide practical tips on how to become a climate-smart cardiovascular healthcare provider. Not long ago, climate change was a fringe topic deemed only ...

Two graduate students from Western University have developed a ground-breaking method for predicting which intensive care unit (ICU) patients will survive a severe brain injury.   Matthew Kolisnyk and Karnig Kazazian combined functional magnetic resonance imaging (fMRI) with state-of-the art machine learning techniques to tackle one of the most complex issues in critical care. Whether it is the result of a stroke, cardiac arrest or traumatic brain injury, lives can forever be changed by a serious brain injury. When patients are admitted to the ICU, families are faced with tremendous uncertainty. Will my loved one recover? Are they aware of what is going on? Will they ever be the same ...

BIRMINGHAM, Ala. – During a bout of influenza, B cells interact with other immune cells and then take different paths to defend the body. One path is the B cells that differentiate into antibody producing cells. Another path is the B cells that differentiate into lung-resident memory B cells, or lung-BRMs, that are critical for pulmonary immunity. Unlike antibody-producing B cells that help fight the current infection, the long-lived, non-circulating lung-BRMs migrate to the lungs from draining lymph nodes. ...
