Researchers from the University of Toronto Engineering and Sunnybrook Hospital have developed a novel type of handheld 3D printer capable of depositing uniform sheets of skin to cover large burn wounds, while its “bio ink” has been shown to accelerate the healing process. Writing in the journal Biofrabrication, the researchers […]

A fungus that attacks almond and peach trees may be key to identifying new drug targets for cancer therapy. A team of Florida State University researchers from the Department of Chemistry and Biochemistry found that a natural product from the fungus Fusicoccum amygdali stabilizes a family of proteins in the […]

Most memories fade in a matter of days or weeks, while some persist for months, years, or even for life. What allows certain experiences to leave such a long-lasting imprint in our neural circuits? This is an age-old question in neurobiology that has never been resolved, but new evidence is […]

Rutgers biomedical engineers have developed a “bio-ink” for 3D printed materials that could serve as scaffolds for growing human tissues to repair or replace damaged ones in the body. The study was published in the journal Biointerphases. Bioengineered tissues show promise in regenerative, precision and personalized medicine; product development; and basic research, […]

For children with high-risk brain tumors that resist standard therapy, the next step is often enrolling in a clinical trial. But connecting these young patients with the most promising therapies in the world is often a complicated and lengthy process. To address this challenge, an elite, global network of children’s […]

It’s no coincidence that some of the worst viral disease outbreaks in recent years — SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus — originated in bats. A new University of California, Berkeley, study finds that bats’ fierce immune response to viruses could drive viruses to replicate […]

Epigenetic clocks are produced by examining age-related changes in DNA methylation, finding combinations of such changes that are consistent across populations, and predict chronological age. These clocks also predict mortality, in the sense that people with higher epigenetic than chronological age tend to have a higher mortality risk, or be more burdened […]

As much as 12 percent of adults in the United States are living with nonalcoholic steatohepatitis (NASH), an aggressive condition that can lead to cirrhosis or liver cancer. After identifying a molecular pathway that allows NASH to progress into liver cell death, University of California San Diego School of Medicine […]

Once a vague scapegoat for a variety of ills, increasing evidence suggests a condition known as “leaky gut” — in which microbes and other molecules seep out of the intestines — may be more common, and more harmful, than previously thought. Leaky gut is most often experienced by older people, […]

An anti-cancer compound developed at the University of Michigan has shown “profound” activity in mouse models against two subtypes of leukemia — representing up to 40% of patients — a U-M research team reports in the Journal of Clinical Investigation. The compound, dubbed MI-3454, inhibits the protein-protein interaction between menin and Mixed Lineage […]

NSF-funded scientists reporting in the journal eLife have revealed that they are closer to understanding a risk factor for stomach cancer: how the bacterium Helicobacter pylori maintains its shape. About half the world's population is chronically infected with H. pylori, a bacterium whose helical, or corkscrew, shape allows it to burrow into the mucus lining of […]

An international team of scientists has identified a protein which is strongly linked to the commonest cause of blindness in developed countries when its levels are raised in the blood. The discovery is a major step forward in the understanding of age-related macular degeneration, which affects 1.5 million people in […]
