Harms of nighttime light exposure passed to offspring
Animals can pass the damaging effects of nighttime light exposure to their offspring, a new study has found, adding to a growing body of evidence that there's a health cost to our increasingly illuminated nights.

Glassfrogs show surprising diversity of parental strategies
New research from Boston University has found that in many species glassfrog mothers brood their eggs during the night the eggs are fertilized, and that this care improves the survival of the eggs, while in almost a third of species glassfrog fathers stay on guard for much longer periods.

UAB creates triple-threat cancer-fighting polymer capsules for guided drug delivery
Chemists have designed triple-threat cancer-fighting polymer capsules that bring the promise of guided drug delivery closer to preclinical testing. These multilayer capsules show three traits that have been difficult to achieve in a single entity. They have good imaging contrast that allows detection with low-power ultrasound, they can stably and efficiently encapsulate the cancer drug doxorubicin, and both a low- and higher-power dose of ultrasound can trigger the release of that cargo.

Built from the bottom up, nanoribbons pave the way to 'on-off' states for graphene
A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the material. 'Confinement changes graphene's behavior,' said An-Ping Li, a physicist at the Department of Energy's Oak Ridge National Laboratory.

Mysterious cosmic explosion surprises astronomers studying the distant x-ray universe
A mysterious flash of X-rays has been discovered by NASA's Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may be of a variety that scientists have never seen before.

Sculpting optical microstructures with slight changes in chemistry
In 2013, materials scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering, grew a garden of self-assembled crystal microstructures. Now, applied mathematicians at SEAS and Wyss have developed a framework to better understand and control the fabrication of these microstructures. Together, the researchers used that framework to grow sophisticated optical microcomponents.

Vaginal bacteria can trigger recurrent UTIs, study shows
A kind of bacteria found in the vagina may trigger recurrent UTIs, according to researchers at Washington University School of Medicine in St. Louis. The findings help explain why sexual activity is associated with UTIs. When it gets into the bladder, the vaginal bacteria Gardnerella vaginalis causes dormant E. coli from a previous infection to start multiplying again, causing another UTI. Gardnerella may also contribute to more serious kidney infections, the study suggests.

MIT study: NIH funding helps generate private-sector patents
Research grants issued by the National Institutes of Health (NIH) contribute to a significant number of private-sector patents in biomedicine, according to a new study co-authored by an MIT professor. The study, published in the journal Science, examines 27 years of data and finds that 31 percent of NIH grants, which are publicly funded, produce articles that are later cited by patents in the biomedical sector.

Solving the mystery of the Arctic's green ice
In 2011, researchers observed something that should be impossible -- a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. So, how was this bloom possible? Using mathematical modeling, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences found that thinning Arctic sea ice may be responsible for these blooms and more blooms in the future, potentially causing significant disruption in the Arctic food chain.

Social bees have kept their gut microbes for 80 million years
Bacteria living in the guts of social bees have been passed down from generation to generation for 80 million years, according to a new study. The finding adds to the case that social creatures, like bees and humans, not only transfer bacteria between one another in their own lifetime -- they have a distinctive relationship with bacteria over time, in some cases even evolving on parallel tracks as species.

Viruses in the oceanic basement
A team of scientists from the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology (SOEST) showed for the first time that many novel viruses are present in the fluids circulating deep in the rocky crust of the seafloor known as the ocean basement. Their recently published study also provides evidence that the viruses are actively infecting the many unusual microorganisms that live in the basement.
