Tourist photographs are a cheap and effective way to survey wildlife Posted: 22 Jul 2019 03:21 PM PDT Tourists on safari can provide wildlife monitoring data comparable to traditional surveying methods, suggests new research. The researchers analyzed 25,000 photographs from 26 tour groups to survey the population densities of five top predators (lions, leopards, cheetahs, spotted hyenas, and wild dogs) in northern Botswana, making it one of the first studies to use tourist photographic data for this purpose. |
Parasitic plants use stolen genes to make them better parasites Posted: 22 Jul 2019 03:21 PM PDT Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host's nutrients. A new study reveals that the parasitic plant dodder has stolen a large amount of genetic material from its hosts, including over 100 functional genes, through a process called horizontal gene transfer. |
Widespread aspirin use despite few benefits, high risks Posted: 22 Jul 2019 03:21 PM PDT Nearly 30 million Americans older than 40 take aspirin daily to prevent cardiovascular disease. More than 6 million Americans take aspirin daily without physician's recommendation. Nearly half of Americans more than 70 years of age without cardiovascular disease, an estimate of nearly 10 million people, take aspirin daily -- despite current guidelines against this practice. |

Toxin responsible for Legionella growth identified Posted: 22 Jul 2019 08:59 AM PDT A team of scientists has discovered that the toxin SidJ in Legionella bacteria enforces a unique modification on human proteins and helps legionella grow inside human cells. SidJ hijacks human protein Calmodulin to its own advantage in one of the classic examples of pathogenic bacteria exploiting the human molecular machinery and turning it against us. This makes SidJ an ideal target to curb Legionella infection. |

Beyond finding a gene: Same repeated stretch of DNA in three neurodegenerative diseases Posted: 22 Jul 2019 08:19 AM PDT Four different rare diseases are all caused by the same short segment of DNA repeated too many times, a mutation researchers call noncoding expanded tandem repeats. Researchers suspect variations of this type of mutation may cause other diseases that have thus far evaded diagnosis by genetic testing. Researchers are excited because instead of finding unique mutations in specific genes, they identified the same mutation in different areas of the genome causing different diseases. |
Combined online self-management for pain, associated anxiety and depression works Posted: 22 Jul 2019 08:19 AM PDT Online symptom self-management works to decrease pain, anxiety and depression and for some, online self-management plus nurse telecare helps even more according to a new study. Pain is the most common physical symptom for which adults seek medical attention in US, while anxiety and depression are the most common mental health symptoms. All three symptoms frequently co-occur in this difficult to treat patient population. |
Using visual imagery to find your true passions Posted: 22 Jul 2019 08:19 AM PDT You may think you know what you like -- how to spend your time or what profession to pursue. But a new study suggests that your pre-existing self-beliefs, as well as cultural stereotypes, may interfere with your memories and keep you from remembering what truly interests you. However, researchers found that one particular mental technique could help us overcome the barriers that block us from finding our passions. |
