For the first time researchers have run an electrical circuit entirely off power in trees. The findings suggest a new power source for wireless sensors — and a way to monitor tree health.

Researchers have discovered a key missing link in the so-called signaling pathway for plant steroid hormones. This discovery marks the first such pathway in plants for which all the steps have been identified. Since this pathway shares many similarities with pathways in humans, the discovery not only could lead to the genetic engineering of improved [...]
Using an animal model of binge eating, researchers discovered that deactivating the basolateral amygdala, a brain region involved in regulating emotion, specifically blocked consumption of a fatty diet. Surprisingly, it had no effect on the rat wanting to look for the food repeatedly.

A molecular signature that helps account for the aggressive behavior of a variety of cancers such as pancreatic, breast and melanoma may also predict the likelihood of successful treatment with a particular anti-cancer drug. The finding could lead to a personalized approach to treatment for a variety of solid tumors that are currently resistant to [...]

Turning grape juice into wine is a stressful business for yeasts. A researcher in Spain has identified the genes in yeast that enable it to respond to stress and is investigating ways to improve yeast performance by modifying its stress response mechanism.

The Lost Orphan Mine below the Grand Canyon hasn’t produced uranium since the 1960s, but radioactive residue still contaminates the area. Cleaning the region takes an expensive process that is only done in extreme cases, but a biochemistry professor is researching the use of sulfate-reducing bacteria to convert toxic radioactive metal to inert substances, a [...]

Active, but non-invasive breast cancer is set free to roam as invasive breast cancer when an overexpressed protein converts it to a different cell type, scientists report.
Strains of Escherichia coli bacteria that cause food poisoning have been shown to have marked differences in the numbers of genes they carry compared to laboratory strains of E. coli. Some of these genes may enable them to survive stresses such as those caused by modern food processing techniques or exploit food sources that laboratory [...]
