Whooping cough bacterium evolving in Australia, research shows
The bacterium that causes whooping cough, Bordetella pertussis, has changed in Australia -- most likely in response to the vaccine used to prevent the disease -- with a possible reduced effectiveness of the vaccine as a result. A team of researchers analyzed strains of Bordetella pertussis from across Australia and found that many strains no longer produce a key surface protein called pertactin.

Engineers develop new materials for hydrogen storage
Engineers have created new ceramic materials that could be used to store hydrogen safely and efficiently. The researchers have created for the first time compounds made from mixtures of calcium hexaboride, strontium and barium hexaboride. They also have demonstrated that the compounds could be manufactured using a simple, low-cost manufacturing method known as combustion synthesis.

Bizarre parasite may provide cuttlefish clues
New research into parasites of cuttlefish, squid and octopus has uncovered details of the parasites’ astonishing life cycles, and shown how they may help in investigating populations of their hosts.

Outgoing behavior makes for happier humans: Across cultures, extroverts have more fun
Happy is as happy does, apparently -- for human beings all over the world. Not only does acting extroverted lead to more positive feelings across several cultures, but people also report more upbeat behavior when they feel free to be themselves.

MRI pinpoints region of brain injury in some concussion patients
Researchers using information provided by a magnetic resonance imaging technique have identified regional white matter damage in the brains of people who experience chronic dizziness and other symptoms after concussion. The findings suggest that information provided by MRI can speed the onset of effective treatments for concussion patients.

European Climate at the plus 2 degrees Celsius global warming threshold
A global warming of 2°C relative to pre-industrial climate has been considered as a threshold which society should endeavor to remain below, in order to limit the dangerous effects of anthropogenic climate change.

New therapy helps to improve stereoscopic vision in stroke patients
Humans view the world through two eyes, but it is our brain that combines the images from each eye to form a single composite picture. If this function becomes damaged, impaired sight can be the result. Such loss of visual function can be observed in patients who have suffered a stroke or traumatic brain injury or when the oxygen supply to the brain has been reduced (cerebral hypoxia). Those affected by this condition experience blurred vision or can start to see double after only a short period of visual effort.

Scientists come up with method of reducing solar panel glare
The glare from solar farms could be a thing of the past, thanks to new research. Researchers have developed a multi-layer anti-reflection coating for glass surfaces, which reduces the sun's reflection from photovoltaic panels while at the same time improving their efficiency. It is applied using the same technology as that used for depositing anti-reflection coatings on eye glasses.

New design for mobile phone masts could cut carbon emissions
A breakthrough in the design of signal amplifiers for mobile phone masts could deliver a massive 200MW cut in the load on UK power stations, reducing carbon dioxide emissions by around 0.5 million tons a year.

Obesity: Are lipids hard drugs for the brain?
Why can we get up for a piece of chocolate, but never because we fancy a carrot? Research has demonstrated part of the answer: triglycerides, fatty substances from food, may act in our brains directly on the reward circuit, the same circuit that is involved in drug addiction. These results show a strong link in mice between fluctuations in triglyceride concentration and brain reward development. Identifying the action of nutritional lipids on motivation and the search for pleasure in dietary intake will help us better understand the causes of some compulsive behaviors and obesity.
