A new paper by University of Montana scientists examines the potential and uncertainties of attempting genetic rescue, a conservation approach that involves moving a small number of individual animals from one population to another to reduce genetic problems and decrease extinction risk.
The good news is that adolescent sexting is not at epidemic levels as reported in some media headlines. The bad news is that it also has not decreased despite preventive efforts by educators and others, according to a much-needed update to what is currently known about the nature and extent of sexting among youth today.
Military deployments to austere environments -- whether humanitarian missions or combat operations -- involve extensive logistical planning, which is often complicated by unforeseen events. Researchers have now created a model aimed at helping military leaders better account for logistical risk and uncertainty during operational planning and execution.
The recent wave of recreational cannabis legalization across the US could generate $22 billion in sales per year, but not everyone is happy about it. New research in the INFORMS journal Marketing Science shows the alcohol industry could be impacted when the substance is legalized.
Radiation levels in parts of the Marshall Islands in the central Pacific Ocean, where the United States conducted nearly 70 nuclear tests during the Cold War, are still alarmingly high. Columbia University researchers tested soil samples on four uninhabited isles and discovered that they contained concentrations of nuclear isotopes that are significantly higher than those found near Chernobyl and Fukushima.
Firms in Japan are changing people's perceptions about common spiders, worms and insect larvae. These seemingly unwanted creatures have unique features that could be useful for many applications that benefit humans, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
Synthetic biologists seek to create new life with forms and functions not seen in nature. Although scientists are a long way from making a completely artificial life form, they have made semi-synthetic organisms that have an expanded genetic code, allowing them to produce never-before-seen proteins. Now, researchers reporting in Journal of the American Chemical Society have optimized a semi-synthetic bacteria to efficiently produce proteins containing unnatural amino acids.
Knee injuries can be a scourge to collegiate and pro athletes alike, but Penn State researchers say a single measurement taken by a clinician may help predict whether a person is at risk for knee instability.
The U.S. recently celebrated the Fourth of July with dazzling fireworks displays in many cities. After the 'oohs' and 'ahhs' faded, some people might have wondered how the lingering gunpowder-scented smoke affected air quality. Now researchers reporting in ACS Earth and Space Chemistry have conducted detailed measurements and found increased levels of several pollutants after an Independence Day fireworks event in Albany, New York.
Scary movies about dolls that can move, like Anabelle and Chucky, are popular at theaters this summer. Meanwhile, a much less menacing animated doll has chemists talking. Researchers have given a foil 'paper doll' the ability to move and do sit-ups with a new material called polymer covalent organic frameworks (polyCOFs). They report their results in ACS Central Science.
