2021 marks 100 years since researchers identified insulin, a hormone produced by the pancreas that regulates the amount of glucose, or sugar, in the blood. Soon after, insulin was shown to be effective in lowering blood glucose in humans with…
Weizmann Institute scientists analyzed around six million blood tests to obtain data on several types of hormones, discovering that some peak in winter/spring and others in summer. Peaks in stress or reproductive hormones may have “evolved to help us cope with seasonal changes in our surrounding environment.”

Antibiotics for cesarean section births are just as effective when they’re given after the umbilical cord is clamped as before clamping – the current practice – and could benefit newborns’ developing microbiomes, according to Rutgers co-authored research. The study, by far the largest of its kind and published in the journal Antimicrobial Resistance & Infection Control, challenges current recommendations for antibiotic use. Administering antibiotics after clamping does not increase the risk of infection at the site of C-section incisions, the study concludes.
New study in mice finds that a high-fat diet allows cancer cells to outcompete immune cells for fuel, impairing immune function and accelerating tumor growth. Findings suggest new strategies to target cancer metabolism, improve immunotherapies.
Researchers at The University of Texas MD Anderson Cancer Center have developed a novel targeted therapy, called POMHEX, which blocks critical metabolic pathways in cancer cells with specific genetic defects. Preclinical studies found the small-molecule enolase inhibitor to be effective in killing brain cancer cells that were missing ENO1, one of two genes encoding the enolase enzyme.
While prostate cancer originates within the prostate, metastasis, or the spread of a tumor from the site of origin to other organs, remains a leading cause of death among people with the disease. Prostate tumors can metastasize to a number of different organs, including the liver, lymph nodes and bone.

Research shows that many marine animals already inhabit the maximum range of breathable ocean that their physiology allows. The findings are a warning about climate change: Since warmer waters harbor less oxygen, stretches of ocean that are breathable today for a species may not be in the future.
Researchers at University of California San Diego School of Medicine report that fructose only adversely affects the liver after it reaches the intestines, where the sugar disrupts the epithelial barrier protecting internal organs from bacterial toxins in the gut.
Penn Study Reveals A Molecular Mechanism That Helps The Body Mount Perfectly Balanced Responses to Deadly Infections
Scientists have discovered that one of the good bacteria found in the human gut has a benefit that has remained unrecognized until now: the potential to reduce the risk for heart disease.
After one consumes food or a beverage containing fructose, the gut helps to shield the liver from damage by breaking down the sugar. However, the consumption of too much fructose can overwhelm the gut, causing fructose to “spill over” into the liver, where it wreaks havoc and causes fatty liver, researchers discovered.

Research on biological mechanisms suggests that relatively minor changes in mitochondrial energy flow and metabolism could offer significant future benefits to patients with complex diseases.
GRAND RAPIDS, Mich. (Oct. 10, 2019) — For years, scientists have used cells grown in petri dishes to study the metabolic processes that fuel the immune system. But a new report in Immunity suggests looking outside the dish and into living organisms gives a drastically different view of the way immune cells process and use energy.
There’s no question that as body weight increases, so too does blood pressure. Now, in a study of mice, Johns Hopkins researchers have revealed exactly which molecules are likely responsible for the link between obesity and blood pressure. Blocking one of these molecules — a signaling channel that’s found in a tiny organ on the side of your neck — effectively lowers blood pressure in obese mice, the researchers reported recently in the journal Circulation Research.
Mount Sinai researchers have identified elemental signatures in baby teeth that are unique to attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, and cases when both neurodevelopment conditions are present, which suggests that the metabolic regulation of nutrients and toxins play a role in these diseases, according to a study published in Translational Psychiatry in September.
