Using cannabis may cause changes in the human body’s epigenome, a study of over 1,000 adults suggests. The epigenome functions like a set of switches, activating or deactivating genes to change how our bodies function.

“We observed associations between cumulative marijuana use and multiple epigenetic markers across time,” says Lifang Hou, a preventative medical doctor and epidemiologist from Northwestern University Feinberg School of Medicine.

Cannabis is a commonly used substance in the United States, with 49 percent of people trying it at least once, Hou and a team of US researchers report in their published paper. Some US states and other countries have made it legal, but we still don’t fully understand its effects on our health.

A protein fragment from the brain could be used to track progression of Alzheimer’s disease. The tell-tale fragment of tau protein was detectable in the cerebrospinal fluid (CSF) of patients with the disease, and researchers now hope to develop a blood test using it.

Alzheimer’s is a disease of errant protein aggregates that include amyloid plaques and then later tau tangles. ‘Amyloid plaques begin to form about 10 to 20 years before the first symptoms of Alzheimer’s,’ says Randall Bateman, a neurologist at Washington University School of Medicine who helped lead the study. ‘Whereas tau tangles begin once the symptoms begin.’

Studies in two patient groups, each with hundreds of people, revealed that levels of the fragment in the CSF were indicative of tau clumps in the brain seen on imaging and were linked to symptoms of cognitive decline.

A newly described type of chemistry in fungi is both surprisingly common and likely to involve highly reactive enzymes, two traits that make the genes involved useful signposts pointing to a potential treasure trove of biological compounds with medical and chemical applications.

It was also nearly invisible to scientists until now.

In the last 15 years, the hunt for molecules from living organisms—many with promise as drugs, antimicrobial agents, chemical catalysts and even food additives—has relied on computer algorithms trained to search the DNA of bacteria, fungi and plants for genes that produce enzymes known to drive biological processes that result in interesting compounds.

Adversity experienced by mothers during their childhood or pregnancy is reflected in their children’s gut microbiomes, a recent study found.

Our gut microorganisms, collectively known as the gut microbiota, affect far more than digestion. Bacteria in our intestinal tracts influence brain activity — and even the likelihood of developing mental disorders. Decades of research have shown that a bacterially imbalanced gut can disrupt many systems in the human body, contributing to obesity, malnutrition and even cancer. In a study published May 10 in Nature, Stanford Medicine researchers and collaborators used an ingestible device to capture the diversity of microorganisms, viruses, proteins and bile in the small intestine.

The proof-of-concept results provide early evidence that there are more comprehensive ways to measure microbiota in the digestive system than current sampling methods — which mostly focus on stool — and shed new light on how resident gut microbes might contribute to human physiology and disease.

“This paper demonstrates a big leap forward in microbial detection and captures the living gut microbiota in a nutshell,” said co-senior author KC Huang, PhD, a professor of bioengineering and of microbiology and immunology, co-senior author with David Relman, MD, a professor of medicine and of microbiology and immunology. “Samples from current tools don’t fully represent what’s going on inside of us. But it’s all we’ve had — until now.”

Triple-negative breast cancer is a combative cancer type with a highly inflated histological grade that leads to poor theragnostic value. Gene, protein, and receptor-specific targets have shown effective clinical outcomes in patients with TNBC. Cells are frequently exposed to DNA-damaging agents. DNA damage is repaired by multiple pathways; accumulations of mutations occur due to damage to one or more pathways and lead to alterations in normal cellular mechanisms, which lead to development of tumors. Advances in target-specific cancer therapies have shown significant momentum; most treatment options cause off-target toxicity and side effects on healthy tissues.

In March 2020, an experiment in science philanthropy was hatched in the span of a five-minute call.

Patrick Collison, the now 34-year-old billionaire CEO of the online payments company Stripe, and economist Tyler Cowen were chewing over a shared concern: Scientific progress seemed to be slowing down. As the first pandemic lockdowns went into effect, researchers were in a holding pattern, waiting to hear if they could redirect their federal grants to COVID-related work. Collison and Cowen worried that the National Institutes of Health wasn’t moving quickly enough, so they launched Fast Grants to get emergency research dollars to virologists, coronavirus experts, and other scientists rapidly.

“We thought: Let’s just do this,” Cowen recalls. “It was a bit like put up or shut up.”
