Revealing the Secret of How Enzymes Differentiate Cellular Messages

DIS3L2 is a molecular that helps maintain the identity of stem cells, protecting them from changing into other types.

T cell receptors are dynamic protein molecules, study found

T cell receptors are not static components as previously believed.

Studies Shed New Light on Early Transmembrane Signaling

Two new studies by researchers at the University of Washington further our understanding of the molecular steps in the PLC cascade, a G protein-coupled receptor signaling mechanism that underlies a wide variety of cellular processes

Better Solar Cells? Method Safely Deposits Novel Metal Oxide Thin Films On Substrates

University at Buffalo chemists have developed a novel way to grow chemically pure, zinc oxide thin films characterized by dense, bristle-like nanostructures and a new method for depositing them on temperature-sensitive substrates...

Synthetic Molecules Emulate Enzyme Behavior For The First Time

When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions.

Chemists Make Beds With Soft Landings: Researchers Create Stable, Highly Pure Helical Peptide Arrays

Bedsprings aren't often found in biology. Now, chemists have succeeded in making a layer of tiny protein coils attached to a surface, much like miniature bedsprings in a frame.

Chemists Create Class Of Carbenes Used To Make Catalysts

Researchers at the University of California, Riverside have successfully created in the laboratory a class of carbenes, highly reactive molecules, used to make catalysts -- substances that facilitate chemical reactions.

UCR Chemists Prepare Molecules That Accelerate Chemical Reactions For Manufacturing Drugs

New molecules help make stable catalysts that work at room temperature

Chemists Discover Twisted Molecules That Pick Their Targets

New York University chemists have discovered how to make molecules with a twist—the molecules fold in to twisted helical shapes that can accelerate selected chemical reactions.

Disease Markers That Will Aid Arthritis Research

A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression.

Male Mice Lacking The Protein PICK1 Mimic One Cause Of Infertility In Men

Globozoospermia is a rare but severe male infertility disorder.

Solving The Mystery Of What Puts Sperm 'In The Mood'

In a potential advance toward a male contraceptive pill and new treatments for infertility, researchers are reporting the identification of key biochemical changes that put sperm "in the mood" for fertilization.

The biochemical buzz on career changes in bees

Scientists are reporting differences in the brains of nurse bees and forager bees.

Toward a long-sought saliva test for autism

Researchers are reporting discovery of abnormal proteins in the saliva of autism patients that could eventually provide a clue for the molecular basis of this severe developmental disorder...

New evidence that people make aspirin’s active principle — salicylic acid

Scientists in the United Kingdom are reporting new evidence that humans can make their own salicylic acid.

Advance toward early diagnosis of chronic obstructive pulmonary disease

Researchers in Finland are reporting identification of the first potential “biomarker” that could be used in development of a sputum test for early detection of chronic obstructive pulmonary disease

An insight into the biochemistry of inborn errors of metabolism for a clinical neurologist

Neurological dysfunction is an important manifestation of inherited metabolic disorders.

Model studies related to vanadium biochemistry: recent advances and perspectives

Increasing evidence on the need of the higher forms of life for vanadium has accumulated during recent years...

The history of biochemistry in India

The name Biochemistry was coined in 1903 by a German chemist named Carl Neuber. However, work in this very living, aspect of chemistry had started much earlier.

An advance on new generations of chemotherapy and antiviral drugs

Researchers are describing progress toward developing a new generation of chemotherapy agents that target and block uncontrolled DNA replication
