ADE Biotec and the INASMET Foundation, both from the Basque Country, after three years of working together, have developed a new purification technique for purines. The technique is based on electroflotation and could be very beneficial for agriculture as it has a high level (80%+) of purification and very low costs (1 euro/m3). Most of the development project has been carried out at a pilot plant on a Toledo pig farm.

Nowadays purines (excrements plus sewage water from farms) constitute one

Researchers have identified a protein fragment that keeps at least one major tumor suppressor gene from preventing cancer like it should. The fragment belongs to a class of proteins known as apoptotic enhancers (ASPP), named for their ability to stimulate programmed cell death, or apoptosis, by the p53 gene.

But a study published in Nature Genetics finds that one member of this group, called iASPP, actually inhibits p53’s normal cell killing power. When iASPP levels were reduced in experime

With a high-tech fix for faulty cellular editing, scientists at Cold Spring Harbor Laboratory have moved a step closer to developing treatments for a host of diseases as diverse as breast cancer, muscular dystrophy, and cystic fibrosis.

Many human diseases have been linked to defects in a cellular editing process called pre-messenger RNA splicing. Adrian Krainer, a molecular biologist at Cold Spring Harbor Laboratory, has spent years investigating this complex editing process, which t

Researchers at the Stowers Institute for Medical Research are gaining new insight into the molecular players involved in the process of vertebral column formation in the embryo.

A research team headed by Dr. Olivier Pourquie, currently an Associate Scientist at the Stowers Institute, were pioneers in providing evidence for an oscillator called the segmentation clock, a timing mechanism responsible for the periodic production of the somites (the precursors of the vertebrae) in the embr

A Mayo Clinic investigation of Interleukin-6, a hormone inside cells often considered a “bad actor” of the immune system because of its association with inflammation injuries and malignant diseases, shows that it also plays a therapeutic role in mice: it protects brain cells.

Interleukin-6 — called IL-6 for short by researchers — may, in fact, be a “white knight” for mouse brain cells, or neurons, as brain cells also are called. These results, while early, may be promising for humans as w

Researchers are reporting progress in understanding whether a second light-sensing pathway in mammals indeed contributes to the detection of ambient light for controlling body functions.

In an article published in the January 10, 2003, issue of the journal Science, the researchers report that the molecule melanopsin is necessary in order for the pupil to constrict properly in response to light, a function termed the pupillary light reflex.
