Setting controlled fires to avoid wildfires Posted: 20 Jan 2020 08:34 AM PST Despite having proven effective at reducing wildfire risks, prescribed burns have been stymied by perceived and real risks, regulations and resource shortages. A new analysis highlights ways of overcoming those barriers, offering solutions for wildfire-ravaged landscapes. |
Wisdom of the crowd? Building better forecasts from suboptimal predictors Posted: 20 Jan 2020 08:34 AM PST Scientists have shown how to combine the forecasts of a collection of suboptimal 'delay embedding' predictors for time series data. This work may help improve the forecasting of floods, stock market gyrations, spatio-temporal brain dynamics, and ecological resource fluctuations. |
Strongly 'handed' squirrels less good at learning Posted: 20 Jan 2020 08:34 AM PST Squirrels that strongly favor their left or right side are less good at learning, new research suggests. |
Becoming less active and gaining weight: Downsides of becoming an adult Posted: 20 Jan 2020 08:34 AM PST Leaving school and getting a job both lead to a drop in the amount of physical activity, while becoming a mother is linked to increased weight gain, conclude two reviews. |
Combined prenatal smoking and drinking greatly increases SIDS risk Posted: 20 Jan 2020 08:34 AM PST Children born to mothers who both drank and smoked beyond the first trimester of pregnancy have a 12-fold increased risk for Sudden Infant Death Syndrome (SIDS) compared to those unexposed or only exposed in the first trimester of pregnancy, according to a new study. |
Local water availability is permanently reduced after planting forests Posted: 20 Jan 2020 08:34 AM PST River flow is reduced in areas where forests have been planted and does not recover over time, a new study has shown. Rivers in some regions can completely disappear within a decade. This highlights the need to consider the impact on regional water availability, as well as the wider climate benefit, of tree-planting plans. |
On the edge between science and art: Historical biodiversity data from Japanese 'gyotaku' Posted: 20 Jan 2020 08:34 AM PST Japanese cultural art of 'gyotaku,' which means 'fish impression' or 'fish rubbing,' captures accurate images of fish specimens. It has been used by recreational fishermen and artists since the Edo Period. Distributional data from 261 'Gyotaku' rubbings were extracted for 218 individual specimens, roughly representing regional fish fauna and common fishing targets in Japan through the years. |
Dozens of non-oncology drugs can kill cancer cells Posted: 20 Jan 2020 08:31 AM PST Researchers tested approximately 4,518 drug compounds on 578 human cancer cell lines and found nearly 50 that have previously unrecognized anti-cancer activity. These drugs have been used to treat conditions such as diabetes, inflammation, alcoholism, and even arthritis in dogs. The findings suggest a possible way to accelerate the development of new cancer drugs or repurpose existing drugs to treat cancer. |
Laser diode emits deep UV light Posted: 18 Jan 2020 06:50 AM PST Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses. |
