On social media, a bizarre trend seems to be emerging: surprise pregnancies when taking the diabetes drug Ozempic and its sister weight loss shot Wegovy.

As People reports, there are a few reasons why people might be getting pregnant unexpectedly when taking these semaglutide-based injectable drugs.

For one thing, Dr. Iman Saleh — an obstetrician, gynecologist, and obesity medicine doctor at New York’s Northwell Health system — tells People that through a roundabout mechanism, the weight people lose on these drugs may be making them more fertile.

“We hope our work will contribute to informed decisions regarding regulatory measures or behavioral interventions to minimize chemical exposure and protect human health,” Tesar said in a statement.

1.8 million. That’s how many people globally have multiple sclerosis, according to the World Health Organization. The agency also found around one in 100 children worldwide have been diagnosed with autism.

“Rigorous safety tests are in place for human health that are evaluated by [the] U.S. Environmental Protection Agency for approval and compliance with all regulatory guidelines,” Brian Sansoni, senior vice president for Communications, Outreach and Membership for the American Cleaning Institute, told Forbes. The ACI represents top cleaning product manufacturers like the Clorox Company and Procter & Gamble. “ACI member company manufacturers make product safety a top priority.” Quats have been known to be effective at killing bacteria, germs, viruses and mold. “The use of cleaning products, disinfectants and their chemistries contribute to public health in homes, schools, healthcare settings and communities every single day,” the ACI said.

Summary: Researchers unveiled a groundbreaking discovery that DNA damage and brain inflammation are vital processes for forming long-term memories, particularly within the brain’s hippocampus.

Contrary to previous beliefs associating inflammation with neurological diseases, this study highlights inflammation’s critical role in memory formation through the activation of the Toll-Like Receptor 9 (TLR9) pathway following DNA damage in hippocampal neurons.

These findings not only challenge conventional views on brain inflammation but also caution against indiscriminate inhibition of the TLR9 pathway, given its importance in memory encoding and the potential risks of genomic instability.

Groundbreaking research has led to the creation of threofuranosyl nucleic acid (TNA), offering enhanced stability and therapeutic potential, with applications in drug delivery and diagnostics.

The DNA carries the genetic information of all living organisms and consists of only four different building blocks, the nucleotides. Nucleotides are composed of three distinctive parts: a sugar molecule, a phosphate group, and one of the four nucleobases adenine, thymine, guanine, and cytosine. The nucleotides are lined up millions of times and form the DNA double helix, similar to a spiral staircase.

Would you wear this? Researchers just revealed a “spiral diopter” contact lens that has multiple focus points, allowing the user to to see clearly at multiple distances. Here’s what volunteers said when they tried it:

New spiral-shaped multifocal lenses bend light in a way that corrects problems seeing up close and far away, even in poor lighting.

March 27, 2024—(BRONX, NY)— Just as you can’t make an omelet without breaking eggs, scientists at Albert Einstein College of Medicine have found that you can’t make long-term memories without DNA damage and brain inflammation. Their surprising findings were published online today in the journal Nature.

“Inflammation of brain neurons is usually considered to be a bad thing, since it can lead to neurological problems such as Alzheimer’s and Parkinson’s disease,” said study leader Jelena Radulovic, M.D., Ph.D., professor in the Dominick P. Purpura Department of Neuroscience, professor of psychiatry and behavioral sciences, and the Sylvia and Robert S. Olnick Chair in Neuroscience at Einstein. “But our findings suggest that inflammation in certain neurons in the brain’s hippocampal region is essential for making long-lasting memories.”

The hippocampus has long been known as the brain’s memory center. Dr. Radulovic and her colleagues found that a stimulus sets off a cycle of DNA damage and repair within certain hippocampal neurons that leads to stable memory assemblies—clusters of brain cells that represent our past experiences. Elizabeth Wood, a Ph.D. student, and Ana Cicvaric, a postdoc in the Radulovic lab, were the study’s first authors at Einstein.
