You can teach an old dog new tricks, but younger dogs learn faster

Science Daily - Tue, 02/02/2016 - 5:18pm
Aging affects the cognitive abilities of dogs, as a recent study shows. A team of scientists studied dogs of different ages working on a specially designed touchscreen and discovered that although all dogs were capable of learning, older dogs learnt more slowly than younger ones. No age-related differences were found regarding long-term memory.

Windows 10 Passes Windows XP In Market Share

Slashdot - Tue, 02/02/2016 - 5:14pm
An anonymous reader writes: Six months after its release, Windows 10 has finally passed 10 percent market share. Not only that, but the latest and greatest version from Microsoft has also overtaken Windows 8.1 and Windows XP, according to the latest figures from Net Applications. Windows 10 had 9.96 percent market share in December, and gained 1.89 percentage points to hit 11.85 percent in January. Maybe it will jump even faster soon, but not necessarily for the best of reasons.

Listeria: Hypervirulent strains with cerebral and placental tropism

Science Daily - Tue, 02/02/2016 - 5:12pm
A large-scale study based on almost 7,000 strains of Listeria monocytogenes -- the bacterium responsible for human listeriosis, a severe foodborne infection -- has concluded. Through the integrative analysis of epidemiological, clinical and microbiological data, the researchers have revealed the highly diverse pathogenicity of isolates belonging to this bacterial species.

Humans evolved by sharing technology and culture

Science Daily - Tue, 02/02/2016 - 5:12pm
New findings from Blombos Cave show that Stone Age man in Africa exchanged technology to a large extent. The more contact between groups, the stronger technology developed. The exchange of tools can explain humans journey from Africa to Europe.Blombos Cave in South Africa gives vast knowledge of our early ancestors as early as 100,000 years ago.

Scientists have put a high precision blood assay into a simple test strip

Science Daily - Tue, 02/02/2016 - 5:12pm
Researchers have developed a new biosensor test system based on magnetic nanoparticles. It is designed to provide highly accurate measurements of the concentration of protein molecules (e.g. markers, which indicate the onset or development of a disease) in various samples, including opaque solutions or strongly colored liquids.

Smallest lattice structure worldwide

Science Daily - Tue, 02/02/2016 - 5:12pm
Scientists have now presented the smallest human-made lattice structure. Its struts and braces are made of glassy carbon. They are smaller than comparable metamaterials by a factor of five. The small dimension results in so far unreached ratios of strength to density. Applications as electrodes, filters or optical components might be possible.

Maps of forests, fields and soils to aid climate change forecasts

Science Daily - Tue, 02/02/2016 - 5:12pm
Detailed maps of the world's natural landscapes could help scientists to better predict the impacts of future climate change. The complex charts of forests, grasslands and other productive ecosystems provide the most complete picture yet of how carbon from the atmosphere is reused and recycled by Earth's natural habitats, say investigators.

Collagen, heparan sulfate coatings alter cell proliferation, attachment

Science Daily - Tue, 02/02/2016 - 5:11pm
A new paper describes methods to optimize characteristics of cells grown in a lab using biomaterial coatings. The research falls within the field of tissue engineering - the use of biomaterials, cells, and natural factors to regenerate tissues and organs lost to disease or injury. The research group has used a biodegradable polymer coated with two common biomaterials -- collagen and heparan sulfate -- to emphasize differences in cell-material interactions in different environments.

EasyJet May Trial Hydrogen Fuel Cells For Taxiing

Slashdot - Tue, 02/02/2016 - 4:32pm
An anonymous reader writes: Low-cost airline easyJet is discussing plans to install hydrogen batteries as part of a proposed zero emission fuel system, which would power its aircraft during taxiing. The budget service revealed designs for a hybrid plane this week, and said that it would begin trialling the technology later this year. The system will involve embedding a hydrogen fuel cell on board the aeroplanes, with the energy captured from the brakes on landing able to power the jet on the ground. As the only waste product from a hydrogen cell would be fresh, clean water, Ian Davies, head of engineering at easyJet, also suggested that this could be used to refill the planes' water systems during the flight, providing a water source for passengers to drink and for flushing toilets.

Uncommon surnames narrate the family history of those who bear them

Science Daily - Tue, 02/02/2016 - 4:08pm
In most societies, surnames are passed on from father to son, just like the Y chromosome. This suggests that men who share the same surnames may have Y chromosomes that are related to one another. A new study analyses this correlation in Spain and reveals that a large number of men who are bearers of the same unusual surnames are distant relatives.
