New optogenetic tool for controlling neuronal signalling by blue light

Posted: 05 Jul 2014 11:00 AM PDT

Scientists have developed a new technology in the field of optogenetics that can remotely control specific receptors by light. They have named this new technology "OptoTrk" and it has succeeded with neuronal differentiation inducement.

Compounded outcomes associated with comorbid Alzheimer's disease, cerebrovascular disease

Posted: 03 Jul 2014 01:23 PM PDT

Anecdotal information on patients with both Alzheimer's disease and cerebrovascular disease have been confirmed by researchers using mouse models in two different studies. The findings, which found elevated levels of homocysteine is associated with a number of disease states, have potentially significant implications for patients with both disorders.

Fondue with chicken causes campylobacter infections in Switzerland

Posted: 03 Jul 2014 09:58 AM PDT

A hotpot with chicken is one of the primary risk factors for a campylobacter infection in Switzerland in winter, a new study shows. At the end of each year, the reported case numbers of this severe intestinal infection increase in Switzerland. According to the new study, this increase over the festive season can be attributed to the consumption of Hot Pots.

Consider water use in climate change policies: Energy efficient technologies can also save water at the same time

Posted: 03 Jul 2014 07:26 AM PDT

There's more to trying to slow down climate change than just cutting greenhouse gas emissions. Technology, policies or plans that aim to do so should also take environmental factors such as water usage into account. A more integrated approach might make some options considerably more attractive than others, especially when implemented in arid countries such as Australia.

Embryology: Unexpected stability and complexity in transcriptional enhancers' interactions

Posted: 03 Jul 2014 06:16 AM PDT

Contrary to what was thought, sequences of DNA called enhancers – which control a gene's output – find their targets long before they are activated during embryonic development, scientists have found. Their study also reveals that, surprisingly, the degree of complexity of enhancers' interactions in the 'simple' fruit fly Drosophila is comparable to what is seen in vertebrates.

Flamingo die-offs: Flexible, standardized post-mortem examinations important in preventing future flamingo die-offs

Posted: 03 Jul 2014 06:16 AM PDT

The lakes of Kenya's Rift Valley boast spectacular pink aggregations of lesser and greater flamingos. Over the last 20 years these populations have suffered a series of unexplained mass mortality events, during which hundreds of thousands of birds die over a period of just a few months.

Zone tropical coastal oceans: Business-as-usual management policies risks well-being of more than 2 billion people

Posted: 02 Jul 2014 09:24 AM PDT

Leading international scientists have published a joint call for societies to introduce and enforce use zoning of Earth's coastal ocean waters, mirroring approaches commonly used to manage and protect land resources. The 24 scientists, from Canada, the USA, the UK, China, Australia, New Caledonia, Sweden and Kenya, underline that 20 percent of humanity -- mostly in developing countries -- lives within 100 km of a tropical coast and urge new management measures as population and climate impacts on coastal waters worsen.

Food allergies: A new, simple method to track down allergens

Posted: 02 Jul 2014 07:24 AM PDT

Scientists have developed a fast and accurate method for determining exactly which proteins cause allergies to milk. The novel approach can extend to other foods as well. Although food allergies are common, sufferers often don't know exactly what in foods cause their allergic reactions. This knowledge could help develop customized therapies, like training the body's immune system to respond to certain proteins found in foods.
