Examining factors that determine creaky voice use

Vocal fry has a bad reputation in American English. A subtype of creaky voice, a feature of speech that sounds gravelly and pulse-like, this manner of speech is sometimes used to form judgment about the speaker. In many languages, the creaky tone changes the meaning of words, as exhibited in Lango spoken in South Sudan or Jalapa Mazatec spoken in Mexico.

Biden wants NIH to have ‘march-in’ power to override patent rights for high-priced drugs

President Joe Biden today stepped into a long-running debate about whether the National Institutes of Health (NIH) has legal authority to override an exclusive patent license granted to drug developers if they charge too much for treatments that relied on agency-funded research. In draft policy guidance, the Biden administration says federal agencies would be able to use so-called...

Day-extension blue light inhibits chrysanthemum flowering when far-red light is included: Study

Most ornamental crops can be classified as long-day, short-day, or day-neutral plants based on their flowering responses to the photoperiod (which is the day length), or the skotoperiod (which is the night length). Chrysanthemum is a common ornamental crop with an obligate short-day flowering response and only flowers when the night length is consistently longer than a critical duration.

Environmental engineers suggest that anaerobic digestion could be used to clean cattle manure, produce fuel

Chemicals—from antibiotics used to keep livestock healthy to pesticides that shield crops from insects and other pests—play an important role in modern agriculture. However, many of these substances accumulate in cow manure used as fertilizer, where they contaminate crops, leach into groundwater, and pollute waterways, posing a threat to human health and the environment.

Three proposals from researchers to meet EU climate goals

The EU countries have decided that the EU is to be climate neutral by 2050. By 2030, greenhouse gas emissions must have been reduced by at least 55% compared to 1990. To meet this target, continued vigorous efforts are needed to reduce emissions, but that alone will not be enough.

Team reviews phosphine ligand-induced structural transformation of metal nanoclusters

A team of researchers has reviewed a unique method for reforming the structures of ultra-small nanomaterials. These nanomaterials, called metal nanoclusters, bridge the gap between the metal atom and the bulk metal, making them highly useful in both basic and applied research. Metal nanoclusters have the potential for wide-ranging applications in the biomedical fields.

Researchers serve up an improved model of indoor pollution produced by cooking

Stir-frying yields more than just tasty dishes like Kung Pao chicken and Hunan beef. It also emits an invisible mixture of gases and particles that pollute indoor air and can be detrimental to human health. Correctly estimating such cooking emissions in a variety of settings is critical for simulating exposure and informing health guidelines aimed at keeping people safe.

Ancient DNA analysis reveals how the rise and fall of the Roman Empire shifted populations in the Balkans

Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's...
