US releases new Arctic strategy as climate threat grows

US President Joe Biden's administration released a new Arctic strategy on Friday as the strategically and environmentally important region suffers worsening effects from climate change and sees increased international competition.

Global warming is melting Arctic ice, opening previously closed areas to navigation and creating new opportunities for countries such as the United States, Russia and China to vie for resources and influence.

Machiavellianism is associated with bullshitting, according to new psychology research

People high in Machiavellianism are more likely to engage in bullshitting, or distorting the truth to achieve their own ends, according to new research published in the British Journal of Social Psychology. The study also indicates that a facet of Machiavellianism is linked to a reduced receptivity to bullshit. The study’s corresponding author, Christian Blötner (@cbloetner) of the University of Hagen in Germany, was doing research about Machiavellianism when he came across a study that examined the relationship between producing bullshit and being receptive to bullshit, which inspired the cur...

Why some evangelical Christians trust their pastors more than their doctors

In 2019, a mere three years ago, public health researchers described the "face" of vaccine hesitancy as middle- and upper-class women of a very specific cultural milieu.

"The rebel forces in America's latest culture war — the so-called anti-vaxxers — are often described as middle- and upper-class women who breast-feed their children, shop at Whole Foods, endlessly scour the web for vaccine-related conversation, and believe that their thinking supersedes that of their doctors," wrote Alfred Lubrano in the Philadelphia Inquirer, reporting on then-recent studies from government public health agencies.

Why do ducklings swim in single file? Just ask this prize-winning scientist named Fish

PHILADELPHIA -- Hanging from the ceiling of the scientist’s office is a hat in the shape of a giant squid. Nearby are toy ducks and whales, along with mementos from the movies "Finding Nemo" and "Jaws." When your name is Frank Fish and you study aquatic creatures for a living, you’d better have an appetite for fun. Fish is a longtime biology professor at West Chester University with decades of serious research under his belt, some of it funded by the military. But at long last this month, he won an award that celebrates his lighter side: an Ig Nobel Prize. The international awards, now in thei...

COVID rebound after Pfizer treatment likely due to robust immune response, study finds

By Leroy Leo and Julie Steenhuysen

(Reuters) - A rebound of COVID-19 symptoms in some patients after taking Pfizer's antiviral Paxlovid may be related to a robust immune response rather than a weak one, U.S. government researchers reported on Thursday.

I was a presidential science adviser – here are the many challenges Arati Prabhakar faces as she takes over President Biden’s science policy office

Arati Prabhakar has been sworn in as director of the Office of Science and Technology Policy and assistant to the president for science and technology after being confirmed by the U.S. Senate, two months following her nomination by President Joe Biden. As the director of OSTP and assistant to the president, she now serves as the confidential science adviser to the president and is also accountable to Congress. Prabhakar is both the first woman and first person of color to hold this role.

I had the pleasure of getting to know Prabhakar during the Clinton administration when she was the director of the National Institute for Standards and Technology and I was director of the National Science Foundation. In 1998, President Bill Clinton selected me to be his director of OSTP and assistant to the president for science and technology, a position I held until the end of the administration in 2001.

Lower empathy partially explains why political conservatism is associated with riskier pandemic lifestyles

New research helps to explain the association between political conservatism and riskier pandemic lifestyles. According to new research published in Discover Social Science and Health, political conservatives tend to be less empathetic, hold more authoritarian beliefs, and feel less threatened by the pandemic, which in turn is associated with reduced adherence to COVID-19 health recommendations. “Although we have seen a lot of evidence showing that political conservatism is associated with lower rates of social distancing, mask usage, sanitizing, and vaccination, I wanted to better understand ...

What’s next for ancient DNA studies after Nobel Prize honors groundbreaking field of paleogenomics

For the first time, a Nobel Prize recognized the field of anthropology, the study of humanity. Svante Pääbo, a pioneer in the study of ancient DNA, or aDNA, was awarded the 2022 prize in physiology or medicine for his breathtaking achievements sequencing DNA extracted from ancient skeletal remains and reconstructing early humans’ genomes – that is, all the genetic information contained in one organism.

His accomplishment was once only the stuff of Jurassic Park-style science fiction. But Pääbo and many colleagues, working in large multidisciplinary teams, pieced together the genomes of our distant cousins, the famous Neanderthals and the more elusive Denisovans, whose existence was not even known until their DNA was sequenced from a tiny pinky bone of a child buried in a cave in Siberia. Thanks to interbreeding with and among these early humans, their genetic traces live on in many of us today, shaping our bodies and our disease vulnerabilities – for example, to COVID-19.

A common parasitic disease called toxoplasmosis might alter a person’s political beliefs

Infection from the common parasite Toxoplasma tends to produce few apparent symptoms. But a new study published in the journal Evolutionary Psychology suggests that the disease can spur changes in a person’s political beliefs and values, most likely through an inflammatory reaction. Toxoplasmosis is caused by the parasite Toxoplasma gondii and is one of the most prevalent parasitic diseases in the world. Infections can spur from situations like consuming uncooked, contaminated meat or cleaning the litter box of an infected cat. The disease most often produces no obvious symptoms in humans but ...

Neuroimaging study suggests serotonin reuptake inhibitor treatment can improve brain ventricle volume

Psychiatric patients using serotonin reuptake inhibitors (SRI) — a commonly used type of antidepressant — show significantly decreased ventricle volume after one month, according to new neuroimaging research published in the journal Chronic Stress. The ventricles are a series of four interconnected cerebrospinal fluid-filled cavities that are located within the brain. Several psychiatry disorders are associated with the enlargement of these ventricles, which appears to be the result of a loss of neurons and/or glia, specialized cells that provide support and protection to the neurons. “We look...
