'Super' enzyme may lead way to better tumor vaccines
A "super" form of the enzyme Akt1 could provide the key to boosting the effect of tumor vaccines by extending the lives of dendritic cells, the immune-system master switches that promote the response of T-cells, which attack tumors, said researchers at Baylor College of Medicine in a... view more (2006-12-04)

Researchers map infectious hepatitis B virus
Using electron cryomicroscopy and computer image analysis, the scientists visualized two intermediate forms of the virus that exist within infected cells. In addition, they were able to determine a three-dimensional map by analysis of infectious hepatitis B virus isolated from patient blood samples.   view more (2006-06-26)

Finding out what the Big Bang and ink jets have in common
It often turns out there is more to commonplace everyday events than meets the eye. The folding of paper, or fall of water droplets from a tap, are two such events, both of which involve the creation of singularities requiring sophisticated mathematical techniques to describe, analyse and predict.   view more (2008-06-04)

Key heart and Alzheimer's disease protein imaged for first time in native state
Researchers for the first time have created a three-dimensional image of apolipoprotein E, a protein long associated with cardiovascular disease and more recently with Alzheimer's disease, as it appears when it is bound to fat-like substances known as lipids.   view more (2006-01-16)

Beyond genes: Lipid helps cell wall protein fold into proper shape
A protein that provides a vital passage through a bacterium's outer cell wall will misfold and malfunction if that wall is built of the 'wrong' material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases... view more (2005-07-18)

Could new discovery about a shape-shifting protein lead to a mighty 'morpheein' bacteria fighter?
A small molecule that locks an essential enzyme in an inactive form could one day form the basis of a new class of unbeatable, species-specific antibiotics, according to researchers at Fox Chase Cancer Center.   view more (2008-06-23)

BC catalyst discovery promises faster, cheaper drug production
Boston College chemists have discovered a substance that will make it possible for scientists to produce scores of pharmaceuticals and other chemicals in a faster, less expensive way.   view more (2006-09-07)

Microprinting Technique for Patterning Single Molecules
A new process for creating patterns of individual molecules on a surface combines control of self-assembled monolayers (SAMs) and a soft lithography technique known as microcontact printing.   view more (2007-02-05)

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health.   view more (2006-04-03)

Cell signaling discovery yields heart disease clues
A pulsing heart cell is giving Oregon Health & Science University researchers insight into how it sends and receives signals, and that's providing clues into how heart disease and other disorders develop.   view more (2005-09-23)

Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached... view more (2007-04-13)

Hybrid molecule causes cancer cells to self-destruct
By joining a sugar to a short-chain fatty acid compound, Johns Hopkins researchers have developed a two-pronged molecular weapon that kills cancer cells in lab tests.   view more (2007-01-04)

Scientists identify prion's infectious secret
Researchers have known for decades that certain neurodegenerative diseases, such as mad cow disease or its human equivalent, Cruetzfeldt-Jakob disease, result from a kind of infectious protein called a prion.   view more (2007-05-10)

Structural basis for photoswitching in fluorescent proteins brought into focus
University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.   view more (2007-04-11)

What happens when ice melts?
How molecules are linked together to form liquid water is the subject of a groundbreaking study due to appear Thursday, Apr. 1 in Science magazine's advance publication web site Science Express. The investigation entitled The Structure of the First Coordination Shell in Liquid Water summarizes the... view more (2004-04-02)

RNA enzyme structure offers a glimpse into the origins of life
Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction required to make new RNA molecules.   view more (2007-03-16)

Scientists capture the speediest ever motion in a molecule
The fastest ever observations of protons moving within a molecule open a new window on fundamental processes in chemistry and biology, researchers report today in the journal Science.   view more (2006-03-03)

Study finds protein is required for human chromosome production
Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified an elusive protein that performs a necessary step in the production of human chromosomes.   view more (2005-10-13)

Tiny molecule controls stress-induced heart disease
A tiny snippet of RNA, a chemical cousin of DNA, controls damage to the heart under several types of stress, researchers at UT Southwestern Medical Center have found.   view more (2007-03-23)

A common denominator of inflammations and fatty liver
Many cancer patients lose a lot of weight during their disease: Fat and muscle mass are reduced, free fatty acids accumulate in the liver, and this eventually leads to fatty liver in affected patients.   view more (2008-05-28)

Protein sensor for fatty acid buildup in mitochondria
Just as homes have smoke detectors, cells have an enzyme that responds to a buildup of fatty acids by triggering the production of a key molecule in the biochemical pathway that breaks down these fatty acids, according to investigators at St. Jude Children's Research Hospital.   view more (2007-02-15)
