Buckyballs on DNA for harvesting light

Organic molecules that capture photons and convert these into electricity have important applications for producing green energy. Light-harvesting complexes need two semiconductors, an electron donor and an acceptor. How well they work is measured by their quantum efficiency, the rate by which photons are converted into electron-hole pairs.

Red light put moths in the mood

Do you dim the lighting and turn on the red light for a romantic night in with your partner? It turns out moths aren't so different in that regard. A new study published in Frontiers in Genetics shows that dim red light boosts sexual activity in a model species, the yellow peach moth Conogethes punctiferalis (family Crambidae), by selectively activating a genetic pathway related to olfaction in the antennae. This pathway ultimately makes males more sensitive to the odor of the female sex pheromone and thus more motivated to mate.

The First High-Precision Mass Flow Meter for Hydrogen Filling Stations Certified to International Standard OIM - Heinrichs Messtechnik GmbH - Kobold Instruments Sdn. Bhd.

An open road ahead for the fuel cell: The first high-precision mass flow meter for hydrogen filling stations certified to international standard OIML R 139 2018 On the road to climate-friendlier mobility, hydrogen is gaining importance as an energy source for fuel cells. However, fueling of hydrogen is more complex than fueling of gasoline and diesel. Unlike other gases, hydrogen heats up as it expands, causing pressure [PR.com]

Certain occupations may be associated with higher rates of heavy drinking

Working in certain occupations may be associated with a higher likelihood of heavy drinking in people aged 40-69 years, according to research published in the open access journal BMC Public Health. The findings could be used to help target public health or work-based interventions aiming to reduce heavy drinking, according to the authors.

Game theory may be useful in explaining and combating viruses

A team of researchers concludes that a game-theory approach may offer new insights into both the spread and disruption of viruses, such as SARS-CoV-2. Its work, described in the Journal of the Royal Society Interface, applies a "signaling game" to an analysis of cellular processes in illuminating molecular behavior.

Overall deaths did NOT increase for most of China during initial COVID-19 outbreak

A new study involving researchers from the University of Oxford and the Chinese Center for Disease Control and Prevention (China CDC) has examined the change in overall and cause-specific death rates during the three months of the COVID-19 outbreak in early 2020. The results are published today in The BMJ.

Incarceration is strongly linked with premature death in US

An analysis of U.S. county-level data found a strong association between jail incarceration and death rates from infectious diseases, chronic lower respiratory disease, drug use, and suicide, in a new study by Columbia University Mailman School of Public Health. The researchers found this was the case to a lesser extent for heart disease and cancer. The study is the first to examine the link between the expansion of the jail population and multiple specific causes of death at the county level, and adds to the growing body of evidence suggesting that decarceration strategies would improve public health. Findings are published online in the journal Lancet Public Health.
