Study reveals large microbial diversity in breast milk

Spanish researchers have traced the bacterial microbiota map in breast milk, which is the main source of nourishment for newborns. The study has revealed a larger microbial diversity than originally thought: more than 700 species.

Women with menopausal transition experience cognitive difficulties

The memory problems that many women experience in their 40s and 50s as they approach and go through menopause are both real and appear to be most acute during the early period of post menopause. That is the conclusion of a study which appears today in the journal Menopause.

Report shows how P. gingivalis manipulates body's immune system to disable normal processes

A new research report published in the Journal of Leukocyte Biology shows how the bacteria known for causing gum disease--Porphyromonas gingivalis--manipulates the body's immune system to disable normal processes that would otherwise destroy it. Specifically, the report shows that this pathogen prompts the production of the anti-inflammatory molecule Interleukin-10 (IL-10).

ParoChip can allow dentists to quickly detect and analyze periodontitis pathogens

Bleeding gums during tooth brushing or when biting into an apple could be an indication of periodontitis, an inflammatory disease of the tissues that surround and support the teeth. Bacterial plaque attacks the bone, meaning teeth can loosen over time and in the worst case even fall out, as they are left without a solid foundation to hold them in place.

Nanoparticle researcher to deliver inaugural presentation at next ACS national meeting

A noted researcher in nanomedicine ― preventing, diagnosing and treating disease with particles so small that thousands fit across the width of a human hair ― will deliver the inaugural presentation in "The Kavli Foundation Emerging Leader in Chemistry Lecture" at the next National Meeting of the American Chemical Society (ACS).

Color of containers where food and drink are served can enhance attributes like taste and aroma

Two researchers from the Polytechnic University of Valencia and the University of Oxford have proven that hot chocolate tastes better in an orange or cream coloured cup than in a white or red one. The study adds to recent research demonstrating how our senses perceive food in a different way depending on the characteristics of the container from which we eat and drink.

Costs and benefits of bigger brains

Bigger brains can make animals, well, brainier, but that boost in brain size and ability comes at a price. That's according to new evidence reported on January 3rd in Current Biology, a Cell Press publication, in which researchers artificially selected guppies for large and small brain sizes.

Researchers uncover new way that some bacteria survive when under siege by antibiotics

Researchers have uncovered a new way that some bacteria survive when under siege by antibiotics.

PKM-zeta-less adult mice still able to form long-term memories

A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation - that it hinges on a single enzyme in the brain - is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.

Researchers create killer T lymphocytes from iPS cells

Researchers from the RIKEN Research Centre for Allergy and Immunology in Japan report today that they have succeeded for the first time in creating cancer-specific, immune system cells called killer T lymphocytes, from induced pluripotent stem cells (iPS cells).

Stanford scientists identify molecular basis for hypertrophic cardiomyopathy

When a young athlete dies unexpectedly on the basketball court or the football field, it's both shocking and tragic. Now Stanford University School of Medicine researchers have, for the first time, identified the molecular basis for a condition called hypertrophic cardiomyopathy that is the most common cause for this type of sudden cardiac death.

PSCA gene’s rs2294008 variant on T nucleotide may increase risk of bladder cancer

Patients who have inherited a specific common genetic variant develop bladder cancer tumors that strongly express a protein known as prostate stem cell antigen (PSCA), which is also expressed in many pancreatic and prostate tumors, according to research at the National Institutes of Health.

Chromatin regulation not governed by a uniform histone code

In a novel use of gene knockout technology, researchers at the University of California, San Diego School of Medicine tested the same gene inserted into 90 different locations in a yeast chromosome - and discovered that while the inserted gene never altered its surrounding chromatin landscape, differences in that immediate landscape measurably affected gene activity.

Statin therapy affects muscles’ energy production

Up to 75 per cent of patients who take statins to treat elevated cholesterol levels may suffer from muscle pain. Scientists at the Center for Healthy Aging at the University of Copenhagen have now identified a possible mechanism underlying this unfortunate side effect.

New insight into 22q11.2 deletion syndrome

Research out of the George Washington University (GW), published in the journal Proceedings of the National Academy of Sciences (PNAS), reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism.

New rat model simulates traumatic or surgical muscle tissue loss in humans

Penetrating soft tissue injuries that may be caused by bullet wounds or motor vehicle accidents, or exposure to explosive devices in military settings, can cause muscle loss resulting in functional disability and cosmetic deformity. Efforts underway to develop tissue engineering solutions to repair and replace damaged and lost muscle will benefit greatly from the availability of robust animal models to test these innovative therapeutic strategies.

Calphotin essential in keeping cellular calcium concentration low

All living cells keep their cellular calcium concentration at a very low level. Since a small increase in calcium can affect many critical cellular functions (an elevated calcium concentration over an extended period can induce cell death), powerful cellular mechanisms ensure that calcium concentration quickly returns to its low level.

Mayo Clinic researchers identify new target to improve treatment of pancreatic cancer

Researchers at Mayo Clinic in Florida have identified a new target to improve treatment of pancreatic ductal adenocarcinoma cancer, which accounts for more than 95 percent of pancreatic cancer cases. This fast-growing, often lethal cancer is resistant to conventional chemotherapy.

Scientists discover process by which mda-9/syntenin contributes to melanoma metastasis

After recently announcing success in eliminating melanoma metastasis in laboratory experiments, scientists at Virginia Commonwealth University Massey Cancer Center have made another important discovery in understanding the process by which the gene mda-9/syntenin contributes to metastasis in melanoma (the spread of skin cancer) and possibly a variety of other cancers.

New technique can precisely add or delete genes in living cells

Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes.
