| Regular marijuana use bad for teens' brains Posted: 09 Aug 2014 11:14 AM PDT Frequent marijuana use can have a significant negative effect on the brains of teenagers and young adults, including cognitive decline, poor attention and memory, and decreased IQ, according to psychologists. "It needs to be emphasized that regular cannabis use, which we consider once a week, is not safe and may result in addiction and neurocognitive damage, especially in youth," said one expert. |
| Happier consumers can lead to healthier environment, research reveals Posted: 09 Aug 2014 11:14 AM PDT The pursuit of true happiness can lead people to lifestyles that will not only be satisfying but will be better for the environment, according to an overview of psychological research. Several studies have determined that people's basic psychological needs include competence, autonomy, positive relationships, self-acceptance and personal growth. And research has shown that rather than fulfilling these needs, the pursuit of money and possessions takes time away from more personally fulfilling activities and social relationships. |
| Ancient shellfish remains rewrite 10,000-year history of El Nino cycles Posted: 08 Aug 2014 01:34 PM PDT Piles of ancient shells provide the first reliable long-term record for the powerful driver of year-to-year climate changes. Results show that the El Niños 10,000 years ago were as strong and frequent as they are today. The study results question how well computer models can reproduce historical El Niño cycles, or predict how they could change under future climates. |
| Water-polluting anxiety drug reduces fish mortality Posted: 07 Aug 2014 06:57 PM PDT A drug that is commonly used to treat anxiety in humans and which regularly finds its way into surface waters through wastewater effluence has been shown to reduce mortality rates in fish. |
| Flood risk visualization software Posted: 07 Aug 2014 06:55 PM PDT New flood information visualization software will be an excellent tool for water resources planning and management as well as for better flood decision making analysis. |
| Solid-state chemistry: Safer and much cheaper methods for extracting metals Posted: 07 Aug 2014 09:14 AM PDT A team of researchers is developing new approaches to chemical synthesis and mineral processing based on solid-state chemistry -- and inspired by examples from nature. The unconventional approaches promise better, safer and far less expensive methods for extracting metals from mineral ores as well as for the scalable synthesis of pharmaceutical drugs. |
| Vaccinating cows could answer serum shortage Posted: 06 Aug 2014 12:39 PM PDT Two birds with one stone: A novel and broad Ebola vaccine in humans or with specially engineered cows could help researchers develop large quantities of Anti-Ebola serum and protect humans against filoviruses. "Vaccines are the best way to completely eradicate an epidemic threat like Ebola," says one expert. "But for those patients who already have the disease, antibody-based therapies could be the best treatment -- it's a way to give the body's own defenses time to ramp up." |
