Researchers Explore Natural Solution to Rid Plumbing of Pathogens

Virginia Tech

Microbes in tap water are mostly harmless, with a few exceptions. A Virginia Tech research team is investigating four harmful pathogens that have been documented in tap water and suggest a natural, probiotic way to deal with dangerous germs.

Mutations Linked to Breast Cancer Treatment Resistance

Michigan Medicine - University of Michigan

Researchers at the University of Michigan Comprehensive Cancer Center have identified a type of mutation that develops after breast cancer patients take anti-estrogen therapies. The mutations explain one reason why patients often become resistant to this therapy.

Crafting a Better Enzyme Cocktail to Turn Plants Into Fuel Faster

Pacific Northwest National Laboratory

Scientists looking to create a potent blend of enzymes to transform materials like corn stalks and wood chips into fuels have developed a test that should turbocharge their efforts. Efforts revolve around the fungus Trichoderma reesei, which churns out enzymes that chew through molecules like complex sugars.

One Dose of HPV Vaccine May Be Enough to Prevent Cervical Cancer

American Association for Cancer Research (AACR)

Women vaccinated with one dose of a human papillomavirus (HPV) vaccine had antibodies against the viruses that remained stable in their blood for four years, suggesting that a single dose of vaccine may be sufficient to generate long-term immune responses and protection against new HPV infections, and ultimately cervical cancer, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Is DNA From Mom or Dad?

Ludwig Cancer Research

A new technique successfully takes on a longstanding challenge in DNA sequencing – determining whether a particular genetic sequence comes from an individual's mother or father. The method, described in a Ludwig Cancer Research study in Nature Biotechnology, promises to accelerate studies of how genes contribute to disease, improve the process of matching donors with organs and help scientists better understand human migration patterns.

Scientists Unlock Secrets of Diabetes Drug

McMaster University

The key is that metformin doesn’t work to lower blood glucose by directly working on the glucose. It works on reducing harmful fat molecules in the liver, which then allows insulin to work better and lower blood sugar levels.

First Earth-Sized, Rocky Exoplanet Found

W. M. Keck Observatory

Kamuela, Hawaii – A team of astronomers has found the first Earth-sized planet outside the solar system that has a rocky composition like that of Earth. This exoplanet, known as Kepler-78b, orbits its star very closely every 8.5 hours, making it much too hot to support life. The results are being published in the journal Nature.

Study Finds a Patchwork of Genetic Variation in the Brain

Salk Institute for Biological Studies

It was once thought that each cell in a person's body possesses the same DNA code and that the particular way the genome is read imparts cell function and defines the individual. For many cell types in our bodies, however, that is an oversimplification. Studies of neuronal genomes published in the past decade have turned up extra or missing chromosomes, or pieces of DNA that can copy and paste themselves throughout the genomes.

Problem of Gender Differences on Physics Assessments Remains Unsolved

American Institute of Physics (AIP)

In a new synthesis of past work, researchers found that women consistently score lower than men on common assessments of conceptual understanding of physics. However, when examining the factors that may account for these differences (such as student background and test-taking strategies), no clear pattern emerged. Thus, despite previous claims that the causes of this gender gap have been pinpointed, the problem remains unsolved and poorly understood. This has critical importance for science education reform.
