On Wednesday, the agency issued a public health alert for dietary supplements containing cesium salts, a kind of mineral salt. These products usually contain a specific formulation known as cesium chloride. The alert warns both customers to not take these products and doctors not to recommend them.
Early signs of cancer can appear years or even decades before diagnosis, according to the most comprehensive investigation to date of the genetic mutations that cause healthy cells to turn malignant.#science #medicine #health #cancer
The findings, based on samples from more than 2,500 tumours and 38 cancer types, reveal a longer-than-expected window of opportunity in which patients could potentially be tested and treated at the earliest stages of the disease.
In a major breakthrough in the global fight against coronavirus, scientists in Australia have developed a lab-grown version of the disease.#science #medicine #health #coronavirus
Described as a "game changer" that will help scientists determine whether a future vaccine is effective, experts at Melbourne's Peter Doherty Institute for Infection and Immunity on Tuesday became the world's first scientific lab outside of China to copy the virus.
A case of the new virus spreading rapidly in China has been reported in a patient in Seattle, Washington, Reuters reports. The patient had recently returned from China, and is clinically healthy but still being monitored. This is the first US case of the virus, which was first detected in Wuhan, a city in central China in late December 2019. It has already sickened around 300 people and killed six.It's getting closer.
The past five years – and the past decade – are the hottest in 150 years, the latest research has shown. It is bringing increasingly severe storms, floods, drought and wildfires, with one scientist saying the records being broken year after year is “the drumbeat of the Anthropocene”. We look at what the five hottest years look like in pictures#science #environment #GlobalWarming #ClimateChange #ClimateCrisis #ClimateBreakdown
Gene and Sandy Ralston are a married couple in their 70s, who also happen to be among North America’s leading experts at searching for the dead.A long, sad, slightly gruesome, but interesting and rewarding read.
Until now, livers could be stored safely outside the body for only a few hours. With the novel perfusion technology, livers -- and even injured livers -- can now be kept alive outside of the body for an entire week. This is a major breakthrough in transplantation medicine, which may increase the number of available organs for transplantation and save many lives of patients suffering from severe liver disease or a variety of cancers.#science #medicine #health
I’m 62 years old as I write this. Like many of my friends, I forget names that I used to be able to conjure up effortlessly. When packing my suitcase for a trip, I walk to the hall closet and by the time I get there, I don’t remember what I came for.#science #neuroscience #CognitiveDecline
And yet my long-term memories are fully intact. I remember the names of my third-grade classmates, the first record album I bought, my wedding day.
This is widely understood to be a classic problem of aging. But as a neuroscientist, I know that the problem is not necessarily age-related.
A novel nanoparticle vaccine that combines two major influenza proteins is effective in providing broad, long-lasting protection against influenza virus in mice, showing promise as a universal flu vaccine, according to a study by the Institute for Biomedical Sciences at Georgia State University.Great news for mice!
Like other drugs, the legal history of the chemical 3,4-methylenedioxymethamphetamine, better known as MDMA, is driven more by fear and politics than science. Developed as a blood-clotting agent in 1912, MDMA gained popularity in the 1970s and ‘80s as a party drug and as a psychotherapy tool used in conjunction with traditional treatments. Though the drug was not approved by the Food and Drug Administration, some therapists incorporated it into their treatment regimens for patients struggling with PTSD, depression, phobias, and relationship problems. They credited MDMA with inducing empathy, hailing the drug as “penicillin for the soul.”If it induces empathy, why would politicians and lawmakers want it legalised?
Using data Lisdahl’s lab had already collected on people with a history of ecstasy use, he found that users showed more depressive symptoms compared to control groups and that users with a specific variant of the S100B gene, which is associated with psychiatric conditions, showed even greater levels of depressive symptoms than users without the variant. To Medina-Kirchner, these results supported the common belief that ecstasy can impair users by causing severe depressive mood disruptions.Isn't it just as likely that people who use MDMA are people who had a history of depressive symptoms?
