Former President Joe Biden has been diagnosed with an “aggressive” form of prostate cancer that has spread to his bones. But what does it mean for this type of cancer to be called aggressive?
As a urologic surgeon who specializes in diagnosing and treating prostate cancer, I often explain to my patients that aggressiveness isn’t based on a single factor. Instead, it comes from understanding how abnormal the cancer cells look, known as the tumor’s grade; how far they’ve spread,…

A Ludwig Cancer Research study has uncovered a surprising link between diet, intestinal microbes and the efficacy of cancer therapy.
Led by Ludwig Princeton’s Asael Roichman and Branch Director Joshua Rabinowitz, the study could help explain why drugs known as PI3 kinase (PI3K) inhibitors — which disrupt an abnormally activated biochemical signaling pathway that spurs cancer cell proliferation — haven’t led to consistent, durable cancer control in patients with solid tumors.
“Many cancer…

To effectively battle cancer, scientists must study the battlefield. Now, in a recent study published in Nature Communications, a multi-institutional research team including The University of Osaka has discovered some crucial intel: localized oxygen deficiency in the colon cancer microenvironment can promote tumor growth.
Until recently, oxygen deprivation, i.e., hypoxia, was thought to suppress tumor progression. Consequently, drugs that block the supply of oxygen to tumors were being used…

A study by scientists at Nanyang Technological University, Singapore (NTU Singapore) has found that implementing robust air pollution control measures could mean Southeast Asian countries prevent as many as 36,000 ozone-related premature deaths each year by 2050.
Ozone-related premature deaths refer to fatalities caused by prolonged exposure to harmful ground-level ozone. The pollutant worsens asthma, heart disease, and other chronic conditions — particularly among the elderly and…

The PREVENTTM risk calculator helped to identify people with plaque buildup in the arteries of the heart, in addition to predicting their risk of a future heart attack, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.
In addition, when combining PREVENT and a coronary calcium score, risk prediction was further improved, with patients with the highest risk of heart attack…

Researchers at the Francis Crick Institute have shown that gonadotrophs, cells in the pituitary gland with a key role in puberty and reproduction, come from two different populations, with the majority produced after birth rather than in the embryo, as previously thought.
A better understanding of when these important cells develop could help researchers and clinicians understand and treat disorders that impact puberty and fertility.
In the pituitary, a small gland located in the middle of…

Hydrogen boride (HB) nanosheets can inactivate viruses, bacteria, and fungi within minutes in the dark conditions. By coating surfaces with HB nanosheets, it rapidly inactivates SARS-CoV-2, influenza virus, and other pathogens. The nanosheets work by denaturing microbial proteins, offering a safe, effective, and versatile antimicrobial coating for everyday items.
The global fight against infectious diseases faces two major challenges: the threat of new pandemic outbreaks and the alarming…

If you’ve ever sat waiting at the doctor’s office to give a blood sample, you might have wished there was a way to find the same information without needles.
But for all the medical breakthroughs of the 20th century, the best way to detect molecules has remained through liquids, such as blood. New research from the University of Chicago, however, could someday put a pause on pinpricks. A group of scientists announced they have created a small, portable device that can collect and detect…

High birth weight is the main risk factor for birth injuries to the anal sphincter muscles of the person giving birth, according to a study at the University of Gothenburg. This new method for predicting the risks could improve care and reduce injuries.
Five percent of women giving birth to their first child in Sweden sustain birth injuries in the form of obstetric anal sphincter injuries (OASI), affecting the muscles responsible for controlling gas and bowel movements. These injuries can…
