Cosmetics company Lush shut down its Facebook, Instagram, TikTok, and Snapchat accounts globally on Friday, citing its concern about the harms of social media in the wake of Facebook whistleblower Frances Haugen's revelations. "In the same way that evidence against climate change was ignored and belittled for decades, concerns about the serious effects of social media are going largely ignored now," the company said in its press release earlier this week.

Scientists believe mRNA vaccines – which have played a crucial role in our fight against Covid-19 – could solve a number of health issues for humans.

Dr Angelique Coetzee, the South African doctor who first spotted the new Covid variant Omicron, says the patients seen so far have had "extremely mild symptoms" - but more time is needed before we know the seriousness of the disease for vulnerable people.

A new study lays out a bit of a conundrum in its opening paragraphs. It notes that scientific progress depends on the ability to update what ideas are considered acceptable in light of new evidence. But science itself has produced no shortage of evidence that people are terrible at updating their beliefs and suffer from issues like confirmation bias and motivated reasoning. Since scientists are, in fact, people, the problems with updating beliefs should severely limit science's ability to progress.

For many of us, the last 20 months have flown by. Experts say that's because the monotony of pandemic life has robbed us of the unique experiences our brains use to make memories and track time.

A new study suggests that self-soothing touch, such as placing a hand over one’s heart, offers similar stress-reducing benefits to being hugged by another person. The study, published in Comprehensive Psychoneuroendocrinology, revealed that both self-touch and receiving a hug from a stranger lowered cortisol levels after a stress induction. ...

Mutilating the sexual organs of a child (circumcision) in the name of culture, religion or dubious preventative medical claims is outrageous and a blatant breach of the child’s human rights. Female genital mutilation is thankfully on the decline and relatively rare in developed countries. The cutting of little boys, however, is not. Approximately one third of males are circumcised worldwide. In this article I intend to highlight the futility and barbarity of the practice.

A science writer investigates the 30-year-old claims of an iconoclastic doctor who said chronic pain was mostly mental.

A plant-based antiviral treatment for Covid-19, recently discovered by scientists at the University of Nottingham, has been found to be just as effective at treating all variants of the virus SARS-CoV-2, even the highly infectious Delta variant.

“This gives us hope that the human immune system is powerful enough to ... eliminate all the functional virus,” said the senior author.

Antibody levels after COVID-19 vaccination vary by age and sex, but across the board, antibody levels dropped significantly within six months. As widely-anticipated decisions about COVID-19 vaccine boosters roll out from U.S. agencies today, insights from an independent study underscore why boosters are important for all adults.

Across decades, topics, and studies, women are more censorious than men. Compared to men, women support more censorship of various kinds of sexual and violent content and content perceived as hateful or otherwise offensive to minorities.

In preliminary testing, the wearable identified infections in open wounds before they looked any different than uninfected wounds.

The Department of Justice (DOJ) on Tuesday sued two major sugar companies in an effort to block them from merging.

A new study found improving public transportation makes it easier for people to make it to their doctor appointments.

A bipartisan coalition of U.S. state attorneys general said on Thursday it has opened a probe into Facebook, now known as Meta Platforms , for promoting its subsidiary Instagram to children despite potential harms.

A self-assembling gel that stimulates nerve regeneration has shown promise as a treatment for paralysis in mice.

Michelle Wacek was a TikTok fan years ago, back when the video-sharing app was called Musical.ly. “I went on it for a laugh,” she says. “And then I got sucked into the vortex.” She took part in lip-syncing challenges, and followed the influencer Evie Meg, who raises awareness about Tourette syndrome among her 14 million followers.

A bipartisan group of state attorneys general is investigating how Instagram attracts and potentially harms children and young adults. The probe follows revelations from a whistleblower about how Instagram's parent company Meta, formerly known as Facebook, has studied the risks of the photo-sharing app to its youngest users, including exacerbating body image issues for some teenage girls.

A new study published in the journal Science Translational Medicine is reporting the development of a novel mRNA-based vaccine designed to help resist tick bites. Preclinical tests in guinea pigs indicate the vaccine aids the immune system in recognizing tick bites, resulting in the parasites being…
