Female mice deprived of dietary zinc before conception experience fertility problems

Female mice deprived of dietary zinc for a relatively short time before conception experienced fertility and pregnancy problems and had smaller, less-developed fetuses than mice that ingested zinc during the same times, according to researchers in Penn State's College of Agricultural Sciences.

Research: Women's faces are rated as more attractive in presence of pleasant odors

New research from the Monell Chemical Senses Center reveals that women's faces are rated as more attractive in the presence of pleasant odors. In contrast, odor pleasantness had less effect on the evaluation of age.

New powerful tool helps identify disease-causing mutations in families

Scientists at the University of Utah (U of U), the University of Texas MD Anderson Cancer Center in Houston and colleagues have developed a powerful tool called pVAAST that combines linkage analysis with case control association to help researchers and clinicians identify disease-causing mutations in families faster and more precisely than ever before.

Regular grape consumption may play role in eye health

New research presented this week at the Association for Research in Vision and Ophthalmology conference in Orlando, Florida suggests that regular grape consumption may play a role in eye health by protecting the retina from deterioration.

Study reveals how BTK mutation triggers drug resistance in CLL patients

A multi-institutional team of researchers has pinpointed exactly what goes wrong when chronic lymphocytic leukemia (CLL) patients develop resistance to ibrutinib, a highly effective, precisely targeted anti-cancer drug.

Researchers use patterned visual stimulation to control rapid re-wiring of nerve circuits

In a new study, published in this week's issue of the journal Science, researchers show for the first time how the brain re-wires and fine-tunes its connections differently depending on the relative timing of sensory stimuli.

Researchers create initial catalog of human proteome, identify 193 novel proteins

Striving for the protein equivalent of the Human Genome Project, an international team of researchers has created an initial catalog of the human "proteome," or all of the proteins in the human body.

Research shows how brain distinguishes specific voices in noisy, distracting environments

Listening to a conversation in the context of a cocktail party presents a great challenge for the auditory system.

New approach provides a viable way to culture hESCs for clinical purposes

To be suitable for medical transplantation, one idea is that human embryonic stem cells (hESCs) need to remain "undifferentiated" i.e. they are not changing into other cell types.

Cancer patients who avoid sugar are doubling remission and survival rates

"Fed Up," produced by Katie Couric and directed by Stephanie Soechtig, reveals secrets of the American food industry and points to direct links between our health and what we eat, with particular emphasis on sugar.

Initial biopsy with epigenetic test rules out prostate cancer up to 88%

A multicenter team of researchers report that a commercial test designed to rule out the presence of genetic biomarkers of prostate cancer may be accurate enough to exclude the need for repeat prostate biopsies in many — if not most — men.

Study defines specific genetic mechanism that explains some of schizophrenia's heritability

The overall number and nature of mutations—rather than the presence of any single mutation—influences an individual's risk of developing schizophrenia, as well as its severity, according to a discovery by Columbia University Medical Center researchers published in the latest issue of Neuron.

Researchers find link between aging and chemicals in environment

Why are some 75-year-olds downright spry while others can barely get around? Part of the explanation, say researchers writing in the Cell Press journal Trends in Molecular Medicine on May 28, is differences from one person to the next in exposure to harmful substances in the environment, chemicals such as benzene, cigarette smoke, and even stress.

Prenatal exposure to flame retardants can be linked to lower IQs

A new study involving Simon Fraser University researchers has found that prenatal exposure to flame retardants can be significantly linked to lower IQs and greater hyperactivity in five-year old children.

New nanoscale structures capable of introducing "cocktail" of multiple drugs into cancer cells

Biomedical engineering researchers have developed daisy-shaped, nanoscale structures that are made predominantly of anti-cancer drugs and are capable of introducing a "cocktail" of multiple drugs into cancer cells.

Scientists report that coating stents with vitamin C reduces implants' risks

Every year, more than 1 million people in the U.S. who have suffered heart attacks or chest pain from blocked arteries have little mesh tubes called stents inserted into their blood vessels to prop them open.

Testing for STI co-infections may improve HIV prevention in Africa

To maximize HIV prevention efforts in South Africa and perhaps the broader region, public health officials should consider testing for other sexually transmitted infections when they test for HIV, according to a new paper in the journal Sexually Transmitted Infections.
