New research presented this Monday at the Geological Society of America’s GSA Connects 2023 meeting by Matthew Lamanna, a paleontologist and the principal dinosaur researcher at Carnegie Museum of Natural History, describes exciting fossil finds from a site known as the Cañadón Tomás Quarry ...

Contributed by Emily Zawacki Pittsburgh, Pa., USA: With its low quantities of rain and soaring high temperatures, the Sahara Desert is often regarded as one of the most extreme and least habitable environments on Earth. While the Sahara was periodically much greener in the distant past, an ancient society living in a climate very similar to today’s found a way to harvest water in the seemingly dry Sahara—thriving until the water ran out. New research that will be presented Monday, 16 Oct., ...

Toronto, Canada A new study published by researchers at the University of Toronto indicates a very high level of resilience among Canadians with arthritis whose activities were restricted due to pain. The vast majority (76%) of these individuals were free of any mental illness in the past year, including depression.  The paper was published online this week in PLOS ONE. More than half (56%) of the respondents went beyond just being free of psychiatric disorders to achieving excellent mental health.  ...

The Texas ocelot (Leopardus pardalis albescens) is endangered due to historic hunting, habitat loss, inbreeding, and traffic collisions. Today, only between 50 and 80 ocelots remain in the US, exclusively in Willacy and Cameron counties in southern Texas. These two populations are isolated from the larger one in northwestern Mexico by highways and urban development. “Here we show that a range of species, including middle-sized carnivores such as bobcats and coyotes, successfully use wildlife exits, a new type of mitigation structure specifically designed for the US endangered ...

This summer, the planet is suffering from unprecedented heat waves and heavy rainfalls. Developing renewable energy and expanding associated infrastructure has become an essential survival strategy to ensure the sustainability of the planet in crisis, but it has obvious limitations due to the volatility of electricity production, which relies on uncertain variables like labile weather conditions. For this reason, the demand for energy storage systems (ESS) that can store and supply electricity as needed is ever-increasing, but lithium-ion batteries (LIBs) currently employed in ESS are not only highly expensive, but also prone to potential fire, so there is an urgent need to ...

A team of European researchers has developed a new test that can accurately measure biological aging in a clinical setting. The discovery was made while studying patients for the aging effects of chronic kidney disease. The new test is an epigenetic clock – a type of biochemical assessment that looks at DNA to understand how well the body is aging in contrast to its chronological age – and is the first of these cutting-edge tests to be proven to perform accurately in a clinical setting, in ...

Scientists from The Florey are among the world’s leading stroke experts who have mapped out how researchers and clinicians can improve outcomes for people who have survived a stroke.

Huntington’s Disease is the most common neurodegenerative disorder controlled by a single gene and is characterized by motor and cognitive deficits and psychiatric symptoms. Currently, no treatments can stop or reverse the disease, but new research from Boston Children’s Hospital suggests that there might be a way to protect the brain and prevent or slow cognitive decline.   Research from the lab of Beth Stevens, PhD suggests that parts of the immune system – complement proteins and microglia – mediate the loss of specific synapses connecting the brain’s cortex and striatum. The findings, recently published in Nature Medicine, could ...

A landmark scientific article on the workplace as a major determinant of health is published today (Thursday, 12 October) in The Lancet, and reveals a global picture of the work-related causes of mental health conditions. Carried by University College Cork (UCC) researchers for the Lancet Series on work and health, the paper illustrates that major progress in population health can be made by an increased focus on improving people’s work environments. The paper, ‘Work-related causes of mental health conditions and interventions for their improvement in workplaces’, ...

As global warming continues to redefine ecosystems, plants are increasingly tasked with swift adaptation to ensure their survival. One primary mechanism facilitating such rapid adaptation is epigenetic memory, specifically DNA methylation. DNA methylation, a form of epigenetic modification, involves the addition of a methyl group to the cytosine bases of the DNA, altering its accessibility in chromatin and modulating gene expression. In the context of a warming climate, changes in DNA methylation can be triggered by environmental factors like increased temperature. Such epigenetic adaptations ...

Cold sensitivity poses a significant challenge for certain essential crops. While there's an indication that these plants may possess cold acclimation capabilities, the molecular dynamics, particularly involving the CRT binding factor (CBF) family, are not fully explored. One primary concern has been the disparity in cold tolerance between temperate plants and tropical species such as the tomato. Additionally, the accumulation of small metabolites, termed cryoprotectants, plays a crucial role in enabling plants to resist damage from low temperatures. Adding ...

Abstract: With the advancements in high-throughput sequencing technologies such as Illumina, PacBio, and 10X Genomics platforms, and gas/liquid chromatography-mass spectrometry, large volumes of biological data in multiple formats can now be obtained through multi-omics analysis. Bioinformatics is constantly evolving and seeking breakthroughs to solve multi-omics problems, however it is challenging for most experimental biologists to analyze data using command-line interfaces, coding, and scripting. Based on experience with multi-omics, we have developed OmicsSuite, a desktop suite that comprehensively integrates statistics and multi-omics analysis and visualization. The suite ...

Even on a good day the environment can be wildly unpredictable, from unexpected gusts of wind to food scarcity, and as humans continue to edge out the natural world, the stress on wild populations is increasing. ‘Bats are critical for the maintenance and stability of many terrestrial ecosystems’, say Mattina Alonge [University of California, Berkeley (UCB), USA] and Lucas Greville (McMaster University, Canada) and the animals are known to be particularly sensitive when under strain. But little was known about the impact that stress might have on their ability to reproduce. Concerned about the effect of stress on already vulnerable bat populations, Alonge and her colleagues ...

(Friday, 13 October 2023, Berlin, Germany) Almost half (42%) of patients with skin disease experience sleep disturbances, a major study presented today at the European Academy of Dermatology and Venereology (EADV) Congress 2023 has revealed.1   The ALL PROJECT, a comprehensive international research initiative, analysed over 50,000 adults across 20 countries to assess the impact of skin diseases.2 Notably, these sleep disturbances were found to have broader implications on patients' quality of life. Nearly half (49%) of patients with skin disease reported reduced productivity at work, in contrast with just one in five (19%) participants without a skin disease.1 The ...

Boston – The Kraft Family Blood Donor Center, which provides lifesaving blood products to patients at Dana-Farber Cancer Institute and Brigham and Women’s Hospital, announced today that it has finished implementing a more inclusive blood donation process, in alignment with updated guidelines issued by the U.S. Food and Drug Administration (FDA) that will allow many gay and bisexual men to donate blood and platelets. On May 11, 2023, the FDA changed its policy to reflect that deferring prospective blood donors based on sexual orientation is no longer supported by data. ...

Back when the biggest fly enthusiasts of 19th century Sweden — Carl Fredrik Fallén, for one, and later Johan Wilhelm Zetterstedt — were collecting insects for what would become Lund University’s entomological collections, they wondered exactly what was that buzzing coming from their can of raisins. Skip forward 200 years, and the humble fruit fly, known better to geneticists as Drosophila melanogaster, is one of the most thoroughly studied animals on the planet. And DNA from Fallén and Zetterstedt’s centuries-old curiosities are still revealing new insights into the fly’s evolution as it spread alongside ...

PHILADELPHIA (October 11, 2023) – Police officers often respond to incidents that do not involve crime or immediate threats to public safety but instead deal with community members facing unmet mental health needs. In response to this, many cities are experimenting with co-deploying police officers alongside health professionals or deploying teams entirely composed of civilian health professionals. Recently, researchers from the  University of Pennsylvania School of Nursing (Penn Nursing) explored the perspectives and preferences about these programs among residents in structurally disadvantaged areas where mental health distress is ...

PLYMOUTH MEETING, PA [October 12, 2023] — New research in the October 2023 issue of JNCCN—Journal of the National Comprehensive Cancer Network finds that intensive local-regional treatment to remove as much tumor as possible (known as “debulking”), in addition to standard systemic therapy, does not impact overall quality of life significantly for people with metastatic colorectal cancer. The researchers examined the ongoing ORCHESTRA trial (NCT01792934) to compare patients treated with standard palliative chemotherapy alone to those who received palliative chemotherapy plus either surgery, ablative therapy, and/or radiotherapy ...

UNIVERSITY PARK, Pa. — True altruism is rare behavior in animals, but a new study by Penn State researchers has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent they inherit it from. For the study, published in the journal Molecular Ecology, the researchers examined the genetics behind “retinue” behavior in worker honey bees, who are always female. After the worker bees are exposed to the queen bee’s pheromone, they deactivate their own ovaries, help spread the pheromone to the other worker bees, and tend to the queen ...

BOSTON – The brain is made up of numerous types of cells that are organized into different structures and regions. Although several important steps have been made towards building models of the human brain, the advances have not produced undistorted 3D images of cellular architecture that are needed to build accurate and detailed models. In new research published in Science Advances, a team led by investigators at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham (MGB), has overcome this challenge to offer scientists and clinicians a comprehensive cellular atlas of a part of the human brain known as Broca’s area, with ...

UNIVERSITY PARK, Pa. — An American born in 2019 will spend a larger share of their lifetime taking prescription drugs than being married or receiving an education, according to new research by Jessica Ho, associate professor of sociology and demography at Penn State. She found that American males will spend approximately 48% of their lives taking prescription drugs. The number jumped to 60% for females. Ho reported her findings this week (Oct. 1) in the journal Demography. “As an American, I’d like ...

Publishing an ad for an apartment or rental home in Spanish may seem like it would broaden the pool of potential renters, but new research shows it can harm rental-seekers’ perception of the property and its neighborhood. Finding a new apartment or home to rent can be nerve-wracking and tedious. It is increasingly digital and there are thousands of websites and Facebook groups for prospective renters to peruse. It can be a fraught endeavor — from vetting Craigslist listings to scrolling through hundreds of different listings to find the ...

A longstanding mystery in science is how the over 100 million individual neurons work together to form a network that forms the basis of who we are – every human thought, emotion and behavior.   Mapping these constellations of cells and discovering their function have been long-standing goals of scores of 21st century molecular cartographers working worldwide as part of the National Institutes of Health’s “Brain Initiative Cell Census Network” project. The overarching ...

A team of researchers from the Icahn School of Medicine at Mount Sinai and Yale University School of Medicine has created the first “multiome” atlas of brain cell development in the human cerebral cortex across six broad developmental time points from fetal development into adulthood, shedding new light on their roles during brain development and disease. “Multiome” refers to the simultaneous analysis of multiple types of genetic information within the same biological sample. They can include the genome, the DNA encoded in our cells; the transcriptome, the RNA copies that the cell makes from the ...
