The predatory red tiger oscar may be scary to zebrafish but it will run from a robot predator. 

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.

Space science missions are a lot like smartphones. News apps and operating systems may not be compatible with older hardware and vice-versa.

Different data processing protocols of individual space missions has limited comparison of data from numerous space missions. Due to the complexity of space exploration, instruments and devices are usually purpose-made and data acquisition as well as number crunching tools are built using mission specific data structures and protocols. The downside: the exchange and comparison of observational data between missions and complex computational models developed by third parties are virtually impossible.

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.

The shorter you are, the more your risk of coronary heart disease, according to a new study. Every 2.5 inches change in height affected your risk of coronary heart disease by 13.5 percent - so a 5 foot 6 inch tall person has a 32% lower risk of coronary heart disease  than a 5 foot tall person because of the latter's shorter stature.

Coronary heart disease is the commonest cause of premature death worldwide. It is the condition where the arteries that supply blood to the heart muscle (coronary arteries) become narrowed due to a deposition of fatty material (plaque) in the walls of the arteries. If a blood clot forms over the plaque then the artery can become completely blocked suddenly giving rise to a heart attack.
