How the hummingbird achieves its aerobatic feats

Posted: 21 Nov 2014 04:21 PM PST

Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds. Now, the most detailed, three-dimensional aerodynamic simulation of hummingbird flight conducted to date has definitively demonstrated that the hummingbird achieves its nimble aerobatic abilities through a unique set of aerodynamic forces that are more closely aligned to those found in flying insects than to other birds.

Tapeworm found living inside a patient's brain: Worm removed and sequenced

A genome of a rare species of tapeworm found living inside a patient's brain has been sequenced for the first time. The study provides insights into potential drug targets within the genome for future treatments.

How to estimate the magnetic field of an exoplanet

Posted: 20 Nov 2014 11:18 AM PST

Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.

Jogging keeps you young: Seniors who run regularly can walk as efficiently as 20-somethings

Posted: 20 Nov 2014 11:14 AM PST

A new study is shedding light on an unexpected benefit of jogging in older adults. The study looked at adults over the age of 65 -- some of whom walk for exercise and some who run for exercise. The researchers found that those who run at least 30 minutes, three times a week were less likely to experience age-related physical decline in walking efficiency than those who simply walked.

Hand dryers can spread bacteria in public toilets, research finds

Posted: 20 Nov 2014 05:21 AM PST

Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new research. Airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.

Sun's rotating 'magnet' pulls lightning towards UK

Posted: 19 Nov 2014 05:48 PM PST

The sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmosphere.

Wild weather in the Arctic causes problems for people and wildlife

Posted: 19 Nov 2014 05:45 PM PST

The residents of Longyearbyen, the largest town on the Norwegian arctic island archipelago of Svalbard, remember it as the week that the weather gods caused trouble.  Temperatures were ridiculously warm – and reached a maximum of nearly +8 degrees C in one location at a time when mean temperatures are normally -15 degrees C. It rained in record amounts.

Physicists discover new subatomic particles

Physicists have discovered two never-before-seen baryonic particles. The finding is expected to have a major impact on the study of quark dynamics.

Ancient New Zealand 'dawn whale' identified

Posted: 18 Nov 2014 03:24 PM PST

Palaeontologists are rewriting the history of New Zealand's ancient whales by describing a previously unknown genus of fossil baleen whales and two species within it. The two whales, which lived between 27-25 million years ago, were preserved in a rock formation near Duntroon in North Otago. At that time the continent of Zealandia was largely or completely under water and the whales were deposited on a continental shelf that was perhaps between 50 to 100 meters deep.
