Study shows vitamin D, calcium supplements fail to protect against colorectal cancer

A large, randomized study at 11 U.S. hospitals including Dartmouth-Hitchcock Medical Center found that vitamin D and calcium supplements fail to protect against developing colorectal cancer.

Set of genes identified in human genome essential for survival, proliferation of human cell lines

Using two complementary analytical approaches, scientists at Whitehead Institute and Broad Institute of MIT and Harvard have for the first time identified the universe of genes in the human genome essential for the survival and proliferation of human cell lines or cultured human cells.

Researchers create high resolution images of telomerase that plays major role in cancer, aging

An enzyme called telomerase plays a significant role in aging and most cancers, but until recently many aspects of the enzyme's structure could not be clearly seen.

Study identifies proteins that could help in treating deafness

Almost 40 million Americans suffer from hearing loss. Right now, there is no way to reverse this condition, largely because auditory hair cells, which sense sound and relay that information to the brain, do not regenerate.

New synthetic process helps study key molecule involved in diabetes, inflammation, aging

A synthetic process developed at Yale University will allow researchers to study a key molecule involved in diabetes, inflammation, and human aging.

New COMPASS platform points directly to protein's likely structure

Searching for the precise, complexly folded three-dimensional structure of a protein can be like hacking through a jungle without a map: a long, intensive process with uncertain direction.

Study shows why cancer anemia therapy stimulates tumor growth

Scientists have shown why a drug widely used to treat chemotherapy-induced anemia in ovarian and breast cancer patients also may shorten survival times in some patients by inadvertently stimulating tumor growth.

Genomic analysis confirms sexual transmission of Ebola virus in Liberia

A suspected case of sexual transmission of Ebola virus disease (EVD) in Liberia was confirmed using genomic analysis, thanks to in-country laboratory capabilities established by U.S. Army scientists in collaboration with the Liberian Institute for Biomedical Research (LIBR).

International consortium provides standard protocol for using Oxford Nanopore's DNA-sequencing device

The MinION, a handheld DNA-sequencing device developed by Oxford Nanopore, has been tested and evaluated by an independent, international consortium coordinated by EMBL's European Bioinformatics Institute (EMBL-EBI).

BAM Project authors propose creation of national network of neurotechnology centers

The authors of the original proposal for the Brain Activity Map (BAM) Project, which inspired the White House's BRAIN Initiative, issued today a position statement in Neuron proposing the creation of a national network of neurotechnology centers.

Scientists use new technology to create gene expression map of inner ear cell development

Using a sensitive new technology called single-cell RNA-seq on cells from mice, scientists have created the first high-resolution gene expression map of the newborn mouse inner ear.

Study finds link between microbial signatures and triple negative breast cancer

Cancer is a result of normal cellular functions going wildly awry on a genetic level. That fact has been known for some time, but increasing evidence is showing that the human microbiome, the diverse population of microorganisms within every person, may play a key role in either setting the stage for cancer or even directly causing some forms of it.

US and German researchers team up to advance quality control of human stem cells

Researchers at The Scripps Research Institute (TSRI) in California, USA, and two German institutes, the Center for Integrated Psychiatry Kiel (ZIP) and the Fraunhofer Institute for Molecular Biology and Applied Ecology IME, have announced a partnership to advance the quality control of human stem cells.

New manganese-based catalyst may accelerate drug discovery, development

Chemists have long believed that inserting nitrogen -- a beneficial ingredient for making many pharmaceuticals and other biologically active molecules -- into a carbon-hydrogen bond requires a trade-off between catalyst reactivity and selectivity.

Researchers successfully convert skin cells into fully functional placenta-generating cells

Regenerative medicine is a new and expanding area that aims to replace lost or damaged cells, tissues or organs in the human body through cellular transplantation. Embryonic stem cells (ESCs) are pluripotent cells that are capable of long-term growth, self-renewal, and can give rise to every cell, tissue and organ in the fetus's body.

Researchers uncover how small heat shock protein interacts with other proteins

In Alzheimer's disease proteins clump together to long fibrils causing the death of nerve cells. Small heat shock proteins can counteract this effect. Scientists, therefore, hope to deploy them as agents in the treatment of neurodegenerative diseases. Using the example of a small heat shock protein, researchers at the Technical University of Munich and the Helmholtz Zentrum Muenchen have now uncovered how the protein interacts with other proteins.

Sleep deprivation can impact outcome of stem cell transplantation, study finds

Drowsy mice make poor stem cell donors, according to a new study by researchers at the Stanford University School of Medicine.

New method uses advanced noninvasive neuroimaging to localize and identify epileptic lesions

Epilepsy affects more than 65 million people worldwide. One-third of these patients have seizures that are not controlled by medications. In addition, one-third have brain lesions, the hallmark of the disease, which cannot be located by conventional imaging methods.

Neutrophils kill invading microorganisms, starve microbes to death

The most frequent immune cells in the human blood, so-called neutrophils, efficiently kill invading microorganisms and slowly starve microbes to death by removing crucial trace elements. This is shown by researchers from Umeå University in Sweden in a study published in a special issue of Metallomics.

Researchers report weak association between brain size and IQ

As early as 1836, the German physiologist and anatomist Friedrich Tiedemann, in an article in the Philosophical Transactions, expressed his opinion that "there is undoubtedly a connection between the absolute size of the brain and the intellectual powers and functions of the mind". With the advent of brain imaging methods (e.g., MRI, PET), reliable assessments of in-vivo brain volume and investigations of its association with IQ are now possible.
