After decades in ornithological obscurity, one of the world's least-known birds is finally coming to light thanks to the persistence of a small group of researchers; a year-long study of the Black Tinamou (Tinamus osgoodi hershkovitzi) has captured some of the first video and sound recordings of this elusive species.
The Black Tinamou is a chicken-sized bird found in the foothills of the eastern Andes, where it lives in tall, dense primary forest. It is extremely difficult to observe due to its secretive habitats and cryptic coloration.
For their study, the researchers focused on the southern Colombia subspecies, doing daily censuses in Alto Fragua Indi Wasi National Park, recording vocalizations, and setting up camera traps to capture images and video.
Our sun is constantly changing. It goes through cycles of activity - swinging between times of relative calm and times when frequent explosions on its surface can fling light, particles and energy out into space. This activity cycle peaks approximately every 11 years. New research shows evidence of a shorter time cycle as well, with activity waxing and waning over the course of about 330 days.
Cancer researchers have identified a key signaling pathway in B-cell lymphoma, a malignant type of blood cancer. They demonstrate that the signaling pathway can be blocked using compounds that are already in clinical development.
Take this quick medical pop quiz: which of the following conditions would you prefer to have during your next stay in hospital? A. Staphylococcus aureus (golden staph) bloodstream infection; or B. a heart attack?
I am guessing most non-medical readers voted for the Staph option and, if my experience is anything to go by, the majority of medical readers will have also made a microbial choice.-->
Scientists have identified a small RNA molecule named miR-182 that can suppress cancer-causing genes in mice with glioblastoma mulitforme (GBM), a deadly and incurable type of brain tumor.
There are 16,000 new cases of the deadly brain tumor reported in the U.S. every year. Patients have a very poor prognosis, with median survival of just 14 to 16 months.
Standard chemotherapy drugs stop cancer cells from reproducing by damaging DNA but the new method instead stops the source that creates those cancer cells: genes that are overexpressing certain proteins.
Carbon capture could play a central role in keeping greenhouse gas emissions out of the atmosphere so many materials are being tested for the purpose of capturing CO2.
New results show that ordinary clay can work just as effectively as more advanced materials. Clay offers many benefits compared to other materials, particularly because other potential materials can be expensive, difficult to produce, toxic and not particularly environmentally friendly. A possible practical future use of this discovery could be to include clays in CO2 filters for industrial-scale CO2 emissions reduction.
The use of asbestos continues to increase in Asia despite clear health hazards. A recent Respirology review notes that with approximately 4.3 billion people and a growing population, Asia will likely see a large crop of asbestos-related lung diseases in the next few decades. Some of the cases will be benign, but it is likely that there will be many cases of mesothelioma and lung cancer.
Efforts are needed to improve the recognition and diagnosis of asbestos-related lung diseases, and government and non-government groups must cooperate to take steps to prevent them.
