A new study reveals that renin-angiotensin system (RAS) genes within the amygdala--the brain region important for traumatic memory processing--express differently when the brain develops fearful memories, such as when people undergo traumatic stress. Researchers have found that medication may potentially be used as a pharmacological blockade of the angiotensin type 1 receptor, thereby improving components of fear memory as assessed by freezing behavior.

Fatty acid supplements may protect children with high cholesterol from heart disease later in life by increasing their blood levels of healthy omega-3 fatty acids, according to a new study. Researchers from the Uniformed Services University of the Health Sciences in Bethesda, Maryland, will present their work virtually this week at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.

A new study by researchers at the VA Portland Health Care System in Oregon found that augmenting traditional treatment for traumatic brain injury (TBI) with morning bright light therapy (MBLT) improved physical and mental symptoms for participants. The team will present their work virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.

High-intensity cycling in very short bursts can lead to performance and health benefits in just 10 minutes a day, according to a new study to be presented virtually this week at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.

The popular herbicide Roundup® has been in the news because of concerns its main ingredient, glyphosate, might cause cancer. Now researchers from Florida Atlantic University (FAU) are evaluating the pesticide for potential neurological impacts. This week, the scientists will present their work virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.

Researchers from Wake Forest School of Medicine in North Carolina have demonstrated that a common diabetes drug inhibits the spread of Clostridioides difficile, or C. diff -- a potentially life-threatening infection commonly acquired during hospital stays. The team will present their work virtually at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.

Deep heat creams widely used by athletes to soothe sore muscles may also boost performance when applied before exercise, according to new research presented virtually this week at the American Physiological Society's (APS) annual meeting at Experimental Biology 2021.

Study first to experimentally explore the joint impact of fishing and ocean warming on fish populations, finding that the viability of wild populations and global fish stock are at risk

The activity of a crucial placental gatekeeper in mice is regulated by the circadian clock, changing during the day-night cycle.

Scientists from the European Molecular Biology Laboratory, together with collaborators from Heidelberg University, have provided further evidence of the gut's role in COVID-19.

New research has resolved a long-standing controversy about an extinct "horned" crocodile that likely lived among humans in Madagascar. Based on ancient DNA, the study shows that the horned crocodile was closely related to "true" crocodiles, including the famous Nile crocodile, but on a separate branch of the crocodile family tree. The study contradicts recent scientific thinking and also suggests that the ancestor of modern crocodiles likely originated in Africa.

Ship movements on the world's oceans dropped in the first half of 2020 as Covid-19 restrictions came into force, a new study shows.

The building of new homes continues in flood-prone parts of England and Wales, and losses from flooding remain high. A new study, which looked at a recent decade of house building, concluded that a disproportionate number of homes built in struggling or declining neighbourhoods will end up in high flood-risk areas due to climate change.

Researchers at RIKEN, Japan have discovered molecular events that determine whether cancer cells live or die. With this knowledge, they found that reduced consumption of a specific protein building block prevents the growth of cells that become cancerous, opening up the possibility of dietary therapy for cancer.

Work performed by dozens of scientists at Pfizer, BioNTech, Texas Biomed, the SNPRC and scientific partners around the world from April to July of 2020 is now published in the scientific journal Nature. In the paper titled "Immunogenic BNT162b vaccines protect rhesus macaques from SARS-CoV-2" published on Feb. 1, 2021, scientists noted the vaccine candidate tested for Pfizer "protected the lower respiratory tract from the presence of viral RNA and with no evidence of disease enhancement."

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes University has found that the vertical turbine design is far more efficient than traditional turbines in large scale wind farms, and when set in pairs the vertical turbines increase each other's performance by up to 15%.

The COVID pandemic appears to have triggered about a 44% increase in insomnia disorder among health care workers at a medical-school affiliated health system, with the highest rates surprisingly among those who spent less time in direct patient care, investigators say.

An international, multidisciplinary team that includes faculty members from The University of Texas at Arlington has published a paper in the journal Philosophical Psychology that wades into the debate about whether fish feel pain.

University of Houston researchers identify messaging formula for businesses to more effectively persuade customers to adopt eco-friendly behavior.

The addition of meat alternatives such as poultry and fish is not reducing the global production and consumption of energy-gobbling land-based meats, according to new research. That conclusion comes from an analysis of 53 years of international data by University of Oregon sociologist Richard York.
