Engineers reprogram yeast cells to become microscopic drug factories

By genetically reprogramming the cellular machinery of yeast they created microscopic factories that convert sugars and amino acids into plant-based drugs. Since antiquity, cultures on nearly every continent have discovered that certain plant leaves, when chewed or brewed or rubbed on the body, could relieve diverse ailments, inspire hallucinations or, […]

New Connections Reveal How Cancer Evades the Immune System

If cancer is a series of puzzles, new study pieces together how several of those puzzles connect to form a bigger picture. One major piece is the immune system and the question of why certain immune cells stop doing their job. Another piece involves how histones are altered within immune […]

How mechanical forces nudge tumors toward malignancy

All cancers are the result of cells that have gone haywire, multiplying out of control and expanding beyond their normal constraints. But not all tumors are the same: for reasons that remain poorly understood, some are more likely to become aggressive and metastasize to other parts of the body. New […]

Scientists Develop First Drug-Like Compounds to Inhibit Elusive Cancer-Linked Enzymes

A team of scientists from the University of Michigan Rogel Cancer Center has developed the first drug-like compounds to inhibit a key family of enzymes whose malfunction is associated with several types of cancer, including an aggressive form of childhood leukaemia. The enzymes — known as the nuclear receptor-binding SET domain […]

Tiny tweezer developed at Vanderbilt can trap molecules on a nanoscale, creating powerful research capabilities into cancer metastasis, neurodegenerative diseases

In 2018, one-half of the Nobel Prize was awarded to Arthur Ashkin, the physicist who developed optical tweezers, the use of a tightly focused laser beam to isolate and move micron-scale objects (the size of red blood cells). Now Justus Ndukaife, assistant professor of electrical engineering at Vanderbilt University, has developed the […]

Swine flu vaccination in pregnant women did not increase risk of autism in offspring

Two recent studies were unable to rule out that H1N1 (“swine flu”) vaccination (“Pandemrix”) and seasonal influenza vaccination given to pregnant women might be associated with autism spectrum disorder in the offspring. Now, a large study by researchers at Karolinska Institutet in Sweden, published in the journal Annals of Internal […]

Study Sheds Light on Survival Mechanism Activated by the Brain in Conditions of Uncertainty

Findings are relevant to an understanding of the neural mechanisms present in mental disorders such as post-traumatic stress disorder and addiction. A new Tel Aviv University study examined the brain's reactions in conditions of uncertainty and stressful conflict in an environment of risks and opportunities. The researchers identified the areas of the […]

Different responses in individual cells give muscles more control

Minute differences in individual muscle cell contractions allow the entire muscle to flex with greater control and accuracy. Long dismissed as “noise” or error, experts now suspect that biological systems may have evolved to include unavoidable variation as a form of information in their communication channels. A team of experts […]

To Treat Frontotemporal Dementia, Treat the Brain’s Immune Cells

The neurodegenerative disease known as frontotemporal dementia (FTD) causes untold suffering. As neurons die in regions of the brain important for maintaining our personalities and living a purposeful life, patients experience steadily worsening cognitive and behavioural symptoms, and the disease is generally fatal within a decade of diagnosis. Though FTD […]

Altered enzyme offers hope for spinal injury and stroke

An enzyme proven to help regrow damaged nerve tissue in animals but too unstable for use in humans has been redesigned for stability in research co-led by Marian Hettiaratchi of the Phil and Penny Knight Campus for Accelerating Scientific Impact at the University of Oregon. With stability added, the enzyme […]

Neurons protect themselves from degeneration by adapting their metabolism

A recent study in Science Advances by researchers at Karolinska Institutet and Max Planck Institute shows that neurons can counteract degeneration and promote survival by adapting their metabolism. It challenges the long-standing view that neurons cannot adjust their metabolism and therefore irreversibly degenerate. These findings may contribute to developing therapeutic […]
