New mechanism of bone growth discovered

In a paper published in the journal Nature, an international research team led by researchers at Karolinska Institutet in Sweden reports that bone growth in mice takes place in accordance with the same principles as when new cells are produced in blood, skin and other tissue. This contradicts the previous understanding that bone growth depends […]

Cancer genes’ age and function strongly influence their mutational status

Researchers have provided new insight on why some genes that formed during the evolution of the earliest animals on earth are particularly impaired (or dysregulated) by specific mechanisms during cancer development. Their study, published today in eLife, suggests investigating the implications of this dysregulation for the entire function of cancer cells may provide useful insights […]

Artificial intelligence could predict spread of melanoma

An interdisciplinary team of researchers at Ben-Gurion University of the Negev (BGU) in Israel and the University of Texas Southwestern Medical Center (UTSW) in Dallas have developed groundbreaking technology to identify melanoma cells that are likely to metastasize to other parts of the body using artificial intelligence (AI). The method, called “quantitative live cell histology,” […]

A gene involved in ADHD could be related to addictive substance use

Some variations in the gene LPHN3, associated with attention deficit/hyperactivity disorder (ADHD) in children and adults, could favour the likelihood to smoke, consume alcohol, cannabis and other addictive substances, according to an article published in the journal Translational Psychiatry, from the Nature Publishing Group. The findings are based on the study of around 2,700 patients—children, […]

Using 1 germ to fight another when today’s antibiotics fail

Bacteria lodged deep in Ella Balasa’s lungs were impervious to most antibiotics. At 26, gasping for breath, she sought out a dramatic experiment—deliberately inhaling a virus culled from sewage to attack her superbug. “I’m really running out of options,” said Balasa, who traveled from her Richmond, Virginia, home to Yale University for the last-resort treatment. […]

Discovery improves understanding of Lou Gehrig’s disease

A collaborative study led by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute of Texas Children’s Hospital improves our understanding of how amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease, develops. A common feature of this progressive, fatal neuromuscular condition is an imbalance between the synthesis and […]

Estrogen made by neurons important to making memories

Estrogen in the brain is important to keep neurons communicating and memories being made, scientists report. Neurons in both males and females make estrogen and the scientists have shown that when they don’t, their brains have significantly less dense spines and synapses—both key communication points for neurons—in the biggest part of their brain, called the […]

Study links diabetes and back pain

People with diabetes have a 35 percent higher risk of experiencing low back pain and 24 percent higher risk of having neck pain than those without diabetes, a review by University of Sydney researchers has found. Their findings, based on meta-analyses of studies that assess the links between diabetes and back or neck pain outcomes, […]
