Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.

Geographic variations in colour perception

It's long been known that color blindness is caused, usually in men, by changes in the red and green opsin genes, the genes that enable humans to perceive color.

Identification of a naturally occurring genetic difference that controls the production of serotonin in the brain

Researchers at Duke University Medical Center have provided the first direct evidence in mice for the role of an enzyme that specifically controls the production of serotonin in the brain.

Protein research may help develop new antibiotics

New findings about a protein that keeps cells alive by opening and closing pores within a cell's membrane may open the door to the development of new antibiotics.

Abnormalities observed in cloned mice help reinforce the need to continue to avoid the reproductive cloning of humans

Dr. Takumi Takeuchi, from Cornell University, New York, USA told a media briefing that he and Dr. Gianpiero Palermo's team had compared imprinting abnormalities (the process where specific genes inherited from both parents are silent) in mice embryos derived from assisted reproduction techniques and from cloning.

$1.6 million ecological stoichiometry grant to study how certain nutrients affect the development of disease in humans and animals

Two University of Kansas and four Arizona State University researchers have received an almost $1.6 million grant from the National Science Foundation to study how certain nutrients affect the development of disease in humans and animals.

Elevated homocysteine levels have been associated with an increased risk of dementia and Alzheimer disease

Patients with Parkinson disease (PD) who also have high levels of homocysteine (an amino acid produced by the body) are more likely to be depressed compared with other patients with PD who have normal levels of homocysteine

New gene found in genetic wasteland

In a region of DNA long considered a genetic wasteland, Harvard Medical School researchers have discovered a new class of gene.

New target to stop breast cancer growth

Two proteins that normally help cells move from place to place and are made in large quantities in breast cancer cells work together to promote the survival and spread of breast cancer, according to a new study by scientists at The University of Texas M. D. Anderson Cancer Center.

African Americans suffer from cardiovascular diseases at a rate about five times higher than the rest of the U.S. population

African Americans suffer from cardiovascular diseases at a rate about five times higher than the rest of the U.S. population. In a new study, scientists may have found a culprit: a serious deficiency of nitric oxide, a small molecule vital in the regulation of blood flow and blood pressure.

High school student makes significant contribution to breast cancer research

A high school student from Albany, New York, has made a significant contribution toward understanding how mutations to a gene called BRCA-1 contributes to hereditary breast cancer.

Students win awards for research into liver disease, cancer and insomnia

Targeting a range of diseases and disorders, three University of Houston students won awards at a recent symposium for research in liver disease, cancer and insomnia.

Four critical components of cells' protein-building machine don't do what scientists had long assumed

In the hunt for these details, scientists have focused on four RNA building blocks, or nucleotides, deep within the machine that are identical in every species, from bacteria to humans. Because they sit where the protein chain is actually built, these "universally conserved" nucleotides in the ribosome were thought to help that process.

Finding overturns long held ideas about how cells build proteins

Writing in the May 28 issue of Cell, Johns Hopkins researchers report that four critical components of cells' protein-building machine don't do what scientists had long assumed.

Study indicates the number of people in the UK who could be incubating vCJD

The Journal of Pathology recently published a paper entitled Prevalence of lymphoreticular prion protein accumulation in UK tissue samples. The study looked at 12,674 stored appendix and tonsil samples, and found that 3 of them showed evidence of the prion protein associated with variant Creutzfeldt-Jakob Disease (vCJD).

Possible new second-generation multiple sclerosis therapy

Scientists from Genencor International, Inc., have demonstrated in an in vivo model that a new variant of recombinant interferon-beta reduces the immunological response to the protein.

Moderate exercise in conjunction with common dietary supplements significantly reduce the risk of atherosclerosis

Moderate exercise in conjunction with common dietary supplements significantly reduce the risk of atherosclerosis because, combined, they boost the body’s production of nitric oxide, which protects against a variety of cardio-vascular disorders, a new UCLA study led by 1998 Nobel Laureate in medicine Louis J. Ignarro shows.

A genetic variant (MTHFR C677T) puts half the population at increased risk of neural tube defects

Researchers in Ireland and the United States identified the genetic make-up (genotype) of 395 individuals born with neural tube defects (spina bifida or encephalocele) and 848 controls.

Scientists have sped up a common jumping gene found in the human genome

Johns Hopkins scientists have transformed a common "jumping gene" found in the human genome into one that moves hundreds of times more often than normal in mouse and human cells.

Risk of artery plaques increased by use of HIV drugs

An Italian study has provided evidence that HIV drugs called protease inhibitors may increase the risk of artery "plaques."

Scientists closer to a potential vaccine or treatment for botulism

By deciphering the near atomic-level structure of the catalytic domain of botulinum toxin type E — one of seven neurotoxins that cause botulism, a disease that paralyzes victims by blocking nerve cells’ ability to communicate — scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are one step closer to a potential vaccine or treatment.
