Females of some whale species have evolved to live drastically longer lives so they can care for their families, new research shows.

Findings from a new study reflect the important role that the gut microbiome (communities of bacteria) plays in the airway health of persons with cystic fibrosis.

Three peer-reviewed journals have recently published research papers by Penn State's Hammel Family Human Rights Initiative. The papers illustrate how the initiative's programs help K-12 educators address difficult issues such as racism.

Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.

Blockage of arterial blood vessels caused by atherosclerosis is largely responsible for heart attacks and strokes, which are the most common causes of death worldwide. The complex mechanisms that lead to pathological changes in the arteries are not yet fully understood. An international research team has now made important progress in understanding this disease and identified potential new approaches for early detection and therapy.

Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.

New findings show the severe impact of fishing gear entanglements on the survival of critically endangered North Atlantic right whales, with every injury from entanglements impacting population recovery.

Researchers have discovered that symptoms of attention-deficit/hyperactivity disorder (ADHD) are tied to atypical interactions between the brain's frontal cortex and information processing centers deep in the brain. The researchers examined more than 10,000 functional brain images of youth with ADHD.

Scientists have developed ultra-thin semiconductor fibers that can be woven into fabrics, turning them into smart wearable electronics.

Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.

Are sleeping pills the only solution for insomnia? Not according to a researcher who says that using self-guided digital behavioral therapy is an alternative solution that should be considered.

Scientists have developed a catalyst for the urea oxidation reaction, enhancing hydrogen generation efficiency.

A largescale new study has found that some people whose genetics are linked to the common iron overload condition haemochromatosis have substantially greater levels of liver, musculoskeletal and brain disease than previously reported, especially at older ages.

Researchers have developed an algorithm that provides an automatic and reliable method of detecting a certain heart defect in newborns.

Defects in the blood vessel network of the central nervous system have been linked to early symptoms of neurodegenerative diseases such as Alzheimer's disease and amyotrophic lateral sclerosis (ALS). It is this complex vascular network that provides the necessary nutrients -- especially glucose and oxygen -- to activate all neuronal functions. A new study reveals that the TDP-43 protein is essential for forming a stable and mature blood vessel network in the central nervous system.

Researchers have combined computational and microbiology laboratory approaches to identify existing drugs that can be repurposed to combat antibiotic-resistant bacterial infections. This research has revealed that a class of steroid drugs currently used in hormone replacement therapy (HRT) can also stop the growth of antibiotic-resistant E. coli and effectively kill MRSA.

Targeting two brain tumor-associated proteins -- rather than one -- with CAR T cell therapy shows promise as a strategy for reducing solid tumor growth in patients with recurrent glioblastoma (GBM), an aggressive form of brain cancer, according to early results from a clinical trial.

Exposure to several combinations of toxic atmospheric pollutants may be triggering asthma symptoms among children, a recent analysis suggests. The study showed that 25 different combinations of air pollutants were associated with asthma symptoms among 269 elementary school children diagnosed with asthma.

A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.

To advance neuromorphic computing, some researchers are looking at analog improvements -- advancing not just software, but hardware too. Research shows a promising new way to store and transmit information using disordered superconducting loops.

Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.

Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.

Research finds a nearly 40% decline in the annual average concentration of respirable particulate matter (PM2.5) in Krakow, Poland, between 2010 and 2019 following the implementation of clean air policies. Air quality improvements translated to substantial benefits for children's outcomes, including fewer cases of asthma and better birth outcomes.

Allergic transfusion reactions (ATRs), a potentially life-threatening side effect of blood transfusions with unclear mechanisms, may be linked to food allergies in pediatric patients as per a recent study by scientists from Japan. They found that ATRs may be triggered by the presence of allergens in the donor's blood, influenced by their pre-donation diet. These findings could pave the way for safer blood transfusions through the development of preventive measures and countermeasures for ATRs.

Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.
