What to Know About MicroRNA, the Nobel-Prizewinning Discovery

Two scientists have been award the 2024 Nobel Prize in Physiology or Medicine for their discovery of microRNA. Victor Ambros, professor of molecular medicine at the University of Massachusetts Chan Medical School, and Gary Ruvkun, professor of genetics at Harvard Medical School and an investigator at Massachusetts General Hospital, received the prize for revealing how microRNAs turn genes on and off.

This isn’t the first time RNA has been honored recently. The molecule has been something of a scientific darling of late: last year, Katalin Kariko and Drew Weissman were awarded the Nobel Prize in Physiology or Medicine for their fundamental discovery that made mRNA-based vaccines possible, a development that transformed the COVID-19 pandemic.

Here’s what the discovery of microRNA means and how it may affect human health.

What is microRNA, anyway?

The discovery makes it possible to manipulate which genes are activated or suppressed in cells. Doing s..

Vaccine exemptions are rising among kindergarteners, CDC reports

A growing number of kindergarten children are starting school without vaccinations due to rising exemptions, according to new data from the U.S. Centers for Disease Control and Prevention (CDC).
Vaccination rates among kindergarteners decreased during the 2023-2024 school year for all reported vaccines, the agency said.
Exemption rates from one or more vaccines rose to 3.3%, an increase from 3.0% in the prior year, the CDC stated.
COVID VACCINE DISTRUST GROWING AMONG AMERICANS
Vaccination coverage is currently at 92.7% for the measles, mumps and rubella (MMR) vaccine.
Approximately 127,000 children in the U.S. started kindergarten with exemptions from one or more vaccines last year.
The exemption increase was reported in 40 states and Washington, D.C.
Fourteen states saw exemption rates exceeding 5%.
Students are required by law to get certain vaccines in all 50 states and Washington, D.C., according to the National Conference of State Legislatures (NCSL).

Having Trouble Quitting Vaping? You’re Not the Only One

Years ago, Dr. Mark Eisenberg, a cardiologist at McGill University in Canada, recommended that one of his patients—a smoker who’d tried everything to quit but still couldn’t—try vaping instead. It worked; his patient kicked the smoking habit. But recently, the same patient came back to Eisenberg’s office with a new problem.

“Now he’s addicted to e-cigarettes,” Eisenberg says. “He said, ‘I want to get off e-cigarettes. What do I do?’”

[time-brightcove not-tgx=”true”]

No one has a very good answer to that question. Almost 20 years after e-cigarettes were introduced in the U.S., going on to attract millions of users, there’s still not enough data on how to stop using them—which research suggests roughly 60% of vapers would like to do.

E-cigarettes are often pitched as an answer to the bane of tobacco use, which claims an estimated 8 million lives around the world per year, says Amanda Graham, chief health officer at Truth Initiative. “So far, that has not come to fruition,” Graham sa..

Yet Another Study Links Acne Creams to Cancer

A new analysis of acne creams and cleansers found dozens, including popular products like Proactiv and Clearasil, contain high levels of a chemical linked to cancer. The findings confirm some of an earlier study that received criticism for its methods, putting more pressure on the U.S. Food and Drug Administration to take action on products widely used by American teenagers.

[time-brightcove not-tgx=”true”]

Researchers tested more than 100 benzoyl peroxide acne products available at major retailers in six states. They found about a third were contaminated with high levels of benzene, a chemical that can cause cancer.

Proactiv contained 18 times the amount of the potent carcinogen allowed in U.S. drugs, the analysis published on Monday in the Journal of Investigative Dermatology found. A CVS-brand face wash had 13 times levels considered safe by the FDA.

“The results presented here suggest that a substantial portion of the BPO [benzoyl peroxide] acne treatment market currently co..

Moving toward healing, Jewish people display ‘resilience’ and will experience ‘renewal,’ says rabbi

Aging slowdown could be surprise benefit of existing medication, research shows

A drug used to prevent organ rejection in kidney transplant patients is being touted for potentially slowing down aging.
The immune-suppressing medication rapamycin, also known as sirolimus, is being used off-label as a means of extending longevity.
«By targeting a key pathway (mTOR) in cells, this drug has been shown to extend lifespan in animals and could be beneficial to prevent age-related diseases in humans,» Dr. Andrea B. Maier — a professor in healthy aging and dementia research at the Director of the Centre for Healthy Longevity at the National University of Singapore — told Fox News Digital.

Lack of sleep during pregnancy could impact baby’s development, study reveals

Sleep is crucial, especially for pregnant women.
Inadequate sleep during pregnancy can have many negative effects, including neurodevelopmental delays for the child, according to a new study.
The research, published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, examined the effects of short sleep duration (SSD) — defined as sleeping fewer than seven hours per night — on pregnant women.

Insufficient sleep during pregnancy was associated with an increased risk of delays in nervous system development, the researchers found.

Best friends have babies on the same day, at the same hospital: ‘Can’t make this stuff up’

Two best friends in Florida got to experience one of life’s most meaningful experiences together — becoming mothers — and it was caught on camera.
