Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life. Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society. “One of our long...

Joint BioEnergy Institute Researchers Identify Key Enzyme Structure The recent discovery that bisabolane, a member of the terpene class of chemical compounds used in fragrances and flavorings, holds high promise as a biosynthetic alternative to D2 diesel fuel has generated keen interest in the green energy community and the trucking industry. Now a second team of researchers with the U.S Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) has determined the three-dimensional...

Study reveals function of glycosylating enzyme involved in muscular dystrophy, brain development and infection by arenaviruses such as Lassa fever; ability to assay enzyme activity could help screen potential muscular dystrophy therapies Researchers at the University of Iowa have worked out the exact function of an enzyme that is critical for normal muscle structure and is involved in several muscular dystrophies. The findings, which were published Jan. 6 in the journal Science, could be...

Case Western Reserve University scientists take step toward cyborg An insect's internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report. The finding is yet another in a growing list from universities across the country that could bring the creation of insect cyborgs — touted as possible first responders to super spies — out of science...

Scientists have determined the structure of the enzyme endomannosidase, significantly advancing our understanding of how a group of devastating human viruses including HIV and Hepatitis C hijack human enzymes to reproduce and cause disease. The findings open the door to the development of new drugs to combat these deadly viruses that infect more than 180 million people worldwide. The team of international scientists led by and Professor Gideon Davies from the University of York and...

A research team led by biochemist Scott Garman at the University of Massachusetts Amherst has discovered a key interaction at the heart of a promising new treatment for a rare childhood metabolic disorder known as Fabry disease. The discovery will help understanding of other protein-folding disorders such as Alzheimer's, Parkinson's and Huntington's diseases, as well. Findings are featured as the cover story in the current issue of Chemistry & Biology. People born with Fabry disease...

The new measurements, by UCLA physics professor Giovanni Zocchi and former UCLA physics graduate student Yong Wang, are approximately 100 times higher in resolution than previous mechanical measurements, a nanotechnology feat which reveals an isolated protein molecule, surprisingly, is neither a solid nor a liquid. "Proteins are the molecular machines of life, the molecules we are made of," Zocchi said. "We have found that sometimes they behave as a solid and sometimes as a liquid. "Solids...

A generally accepted 44-year-old assumption about how certain kinds of bacteria make energy and synthesize cell materials has been shown to be incorrect by a team of scientists led by Donald Bryant, the Ernest C. Pollard Professor of Biotechnology at Penn State University and a research professor in the Department of Chemistry and Biochemistry at Montana State University. The research, which will be published in the journal Science on 16 December 2011, is expected to help scientists discover...

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) — the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers — plays an important role in the regulation of a signaling pathway implicated in biological malfunctions...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
