“Forever chemicals,” or perfluoroalkyl and polyfluoroalkyl substances (PFAS), have made quite a few appearances in the news cycle lately. These thousands of manufacturing chemicals leach into the food and water supply, making it nearly impossible to avoid absorption into the human body. Once in the body, they don’t go away—hence the name “forever chemicals”—and can cause a host of health concerns, from thyroid disease and cancer to liver damage and fertility issues.

What determines how generous a person you are? Could it be how much money you have? How kind you are? Or maybe it comes down to your values. These all seem reasonable assumptions, but a new study from Berkeley University suggests something that feels as trivial as how well you’ve slept lately can also affect how willing you are to help other people on any given day. It found sleep deprivation leads to a reduction in generosity.

Generation Z – those born after 1995 – overwhelmingly believe that climate change is being caused by humans and activities like the burning of fossil fuels, deforestation and waste. But only a third understand how livestock and meat consumption are contributing to emissions, a new study by the University of Sydney and Curtin University researchers has revealed.

Specks of dust retrieved by a Japanese space probe from an asteroid some 300 million kilometres from Earth have revealed a surprising component: a drop of water, scientists said Friday. The discovery offers new support for the theory that life on Earth was seeded from outer space.

Studies collectively examined nearly 30,000 samples over the past five years in ‘disturbing’ findings

A new method to detect Parkinson’s disease has been determined by analysing sebum with mass spectrometry. The study, published today in the Journal of the American Chemical Society, have found that there are lipids of high molecular weight that are substantially more active in people suffering from Parkinson’s disease.

Scientists at CERN think they may have discovered a new source of clean energy.

Researchers from the Institute of Biotechnology, University of Helsinki, pioneers in identifying the first patient mutations on the NFkB1-gene, cooperated with international clinicians to identify and characterise a plethora of unreported NFKB1 variants on patients with immune system related illnesses.

Trigger warning: don’t read this when you’re eating. The common house fly could pose a health risk if it lands on your food.

Cyborg cockroaches in Japan are undergoing testing with electronic backpacks. Researchers use a remote control to direct the cockroaches' movements. Scientists are hoping the breakthrough research will help in search and rescue missions.

People with dark personality traits are more likely to want to enhance their brain power with futuristic technologies, according to new research published in the Journal of Cognitive Enhancement. “Enhancement of human abilities has been a prominent topic throughout human history, but has received little attention from psychological research,” said study author Elena Schönthaler of the University of Graz.

Researchers from UC Davis looked at how the politically polarized nature of COVID-19 information, and misinformation, on social media has given rise to anxiety, sadness, anger and hostility that feeds incivility.

If a woman contracts COVID-19 during her pregnancy, the infection, even if it’s mild, damages the placenta’s immune response to further infections, a UW Medicine-led study has found. The study was published Sept. 17 in the American Journal of Obstetrics & Gynecology.

Some companies offer tests that rank embryos based on their risk of developing complex diseases such as schizophrenia or heart disease. Are they accurate — or ethical?

Since the global pandemic began in 2020, the world has become ever more aware that the health of our species is closely intertwined with other animals. Today, the conversation is mostly focused on birds and mammals, with amphibians rarely considered – but that may be a dangerous oversight.

A heated, plant-based foam has been shown to kill weeds as effectively as a commercial chemical spray and may be a safer, eco-friendlier alternative. “It’s really fascinating, it works very well regardless of the weed growth stage,” says Ilias Travlos at the Agricultural University of Athens, who conducted an independent study of the hot foam at two small olive groves in Greece.

The percentage of Hispanics in the U.S. who identify as atheist or agnostic grew in the past 12 years.

Recent findings published in the journal Scientific Reports shed new light on the risks associated with the use of steroids among male athletes. This time, researchers found that bodybuilders with a history of steroid use were more likely to exhibit psychopathic tendencies, sexual and substance use risk-taking behaviors, and anger issues.

In a remote cave in northeast India, rainwater has slowly dripped from the ceiling in the same spots for over 1,000 years. With each drop, minerals in the water accumulate on the floor below, slowly growing into calcium carbonate towers known as stalagmites. These stalagmites are more than geological wonders – like tree rings, their layers record the region’s rainfall history. They also carry a warning about the potential for catastrophic multiyear droughts in the future.

Five seriously ill lupus patients have seen their disease driven into remission after a single infusion of modified immune cells, in a small trial that borrows from cancer therapy to harness patients' own cells to treat the autoimmune condition.
