Scientists have designed a brain implant that restored lost memory function and strengthened recall of new information in laboratory rats — a crucial first step in the development of so-called neuroprosthetic devices to repair deficits from dementia, stroke and other brain injuries in humans.

A study, conducted in baboon primates, finds that when mothers are even moderately undernourished while pregnant and breastfeeding, their offspring are consistently found to be prediabetic before adolescence. It is the first time that diabetes has been shown to have prenatal origins in a primate model.

There is an intimate and complex relationship between inflammation and cancer; and it is well established that tumors secrete many different chemicals that attract host cells which drive inflammation and help to support tumor growth. Now, a new study published by Cell Press in the June issue of the journal Cancer Cell identifies a single protein that is required for trafficking of immune cells involved in inflammation. The research opens up new avenues for therapeutics that can indirectly suppress malignancy by disrupting the inflammatory response.

In a new study published in the inaugural issue issue of the Journal of Parkinson's Disease, an international group of researchers report that platelet-derived growth factor-BB (PDGF-BB) restored function in rodents and shows promise as a clinical candidate drug for treatment of PD.

For Popeye, spinach was the key to extra muscle. For the mice in a new University of Iowa study, it was apples, or more precisely a waxy substance called ursolic acid that's found in apple peel.

The award-winning research, led by Professor Chris Shaw at Queen's School of Pharmacy, has identified two proteins, or ‘peptides’, which can be used in a controlled and targeted way to regulate 'angiogenesis' – the process by which blood vessels grow in the body.

Research from the University of Louisville published today (June 6) in the Proceedings of the National Academy of Sciences indicates the removal of a tiny RNA molecule in mice suppresses carcinogenic tumor formation.

A study in a special early online publication of Cell, a Cell Press publication, reveals a promising new slow-release compound that protects mice against the neurodegenerative effects of both Huntington's and Alzheimer's disease. The 'prodrug' known only as JM6 works through a pathway involved in the breakdown of the amino acid tryptophan.

Eating a high-fat diet during pregnancy increases the chance of stillbirth, according to new research at Oregon Health & Science University. The new data show eating a typical American diet, which is high in fat, decreases blood flow from the mother to the placenta, the temporary organ that nourishes the unborn fetus.

Scientists at Dana-Farber Cancer Institute have identified an overactive network of growth-spurring genes that drive stem-like breast cancer cells enriched in triple-negative breast tumors, a typically aggressive cancer that is highly resistant to current therapies.
