Broccoli sprout extract may protect against oral cancer recurrence

Thu, 23/06/2016 - 1:52pm
Potent doses of broccoli sprout extract activate a 'detoxification' gene and may help prevent cancer recurrence in survivors of head and neck cancer, according to a 'green chemoprevention' trial. It is the first study demonstrating that the extract protects against oral cancer, with the results of human, animal and laboratory tests reported today.

New findings challenge current view on origins of Parkinson's disease

Thu, 23/06/2016 - 1:52pm
'Mutant flies' have provided insight into the origins of Parkinson's disease, report scientists. The work found that the death of neurons associated with the disease was prevented when chemicals that block the effects of endoplasmic reticulum stress were used.

Maternal social status, sibling rivalry shape milk transfer in spotted hyenas

Thu, 23/06/2016 - 10:52am
Females of low social status often have limited access to food resources. As a result, their offspring are nursed infrequently and may experience long fasting periods that can seriously compromise their growth and survival. In particular when they have to share their milk intake with a littermate, milk shortage can be very detrimental. Yet researchers found that low-ranking spotted hyenas were able to compensate to some extent for their low nursing frequency. They do this by transferring more milk of superior nutritional quality to their offspring than high-ranking mothers during nursing bouts. The results also reveal that the socially dominant offspring in twin litters efficiently uses aggression against its subordinate littermate to skew milk transfer in its favor.

Mycobacterium in olive oil for cancer treatment

Thu, 23/06/2016 - 10:52am
Researchers announced one year ago that the cells of the Mycobacterium brumae offer an improved alternative to current bladder cancer treatments such as BCG (an immunotherapy based on the Mycobacterium bovis), which can cause infections.

World map of resistance to artemesinin anti-malarial medicines

Thu, 23/06/2016 - 10:52am
Practically all currently available treatments for malaria are based in some form or other on a derivative of artemisinin, a plant substance that is found in the leaves and flowers of annual mugwort (Artemisia annua). However, more and more malaria parasites are becoming resistant to artemesinin – especially in South-East Asia. In order to provide an accurate view of the spread of resistance throughout the world, an international research group from more than 50 countries has drawn up a map of artemesinin resistance.

GraphExeter illuminates bright new future for flexible lighting devices

Thu, 23/06/2016 - 10:51am
Researchers have pioneered an innovative new technique to make flexible screens more effective and efficient. GraphExeter -- a material adapted from the 'wonder material' graphene -- can substantially improve the effectiveness of large, flat, flexible lighting, say investigators.

Do you know what you're smoking? Research suggests that you don't

Thu, 23/06/2016 - 10:50am
There is little awareness of the chemical components of cigarette smoke amongst US adults, even though many of them report having looked for relevant information. In a new study, researchers suggest that the Food and Drug Administration (FDA) expand its messaging activities so that information about these constituents reaches all segments of the US population, especially those most vulnerable to tobacco product use and its associated health risks.

Next-generation fluorescent, LED lighting thanks to new phosphor?

Thu, 23/06/2016 - 10:50am
Researchers have discovered a new phosphor that could make next-generation fluorescent and LED lighting even cheaper and more efficient. The team used highly luminescent clusters of silver atoms and the porous framework of minerals known as zeolites.

Successful first observations of galactic center with GRAVITY

Thu, 23/06/2016 - 10:50am
A European team of astronomers have used the new GRAVITY instrument at ESO's Very Large Telescope to obtain exciting observations of the center of the Milky Way by combining light from all four of the 8.2-meter Unit Telescopes for the first time. These results provide a taste of the groundbreaking science that GRAVITY will produce as it probes the extremely strong gravitational fields close to the central supermassive black hole and tests Einstein's general relativity.

Unexpected findings reveal insight into how cancer spreads in the body

Thu, 23/06/2016 - 10:50am
Cancer cells appear to depend on an unusual survival mechanism to spread around the body, according to an early study. The discovery could help with future development of novel treatments to prevent metastasis and secondary tumors.

Loss of essential protein in the choroid plexus epithelium linked to hydrocephalus

Thu, 23/06/2016 - 10:50am
A team led by researchers reports that mice lacking the protein Alix develop hydrocephalus or 'water on the brain.' Alix ensures that epithelial cells of the choroid plexus are oriented correctly with respect to one another to prevent compromise of the epithelial barrier.

Researchers find more uses for immune system's 'Swiss army knife'

Thu, 23/06/2016 - 10:50am
MAIT cells are little know but have been shown to be generally active against bacteria, unlike other T-cells which respond to specific pathogens. Now, researchers have found that they can respond to chemical messengers in the immune system to respond to viruses as well.

Scientists find two ways to limit the number of heat-related deaths from climate change

Thu, 23/06/2016 - 10:50am
By the 2080s, as many as 3,331 people could die every year from exposure to heat during the summer months in New York City. The high estimate is based on a new model -- the first to account for variability in future population size, greenhouse gas trajectories, and the extent to which residents adapt to heat through interventions like air conditioning and public cooling centers.

Engineers develop new, low-cost way to capture carbon

Wed, 22/06/2016 - 11:26pm
A research team reports an unconventional reversible chemical reaction in a confined nanoenvironment. The discovery, a milestone in clarifying the scientific underpinnings of moisture-swing chemical reaction, is critical to understanding how to scrub carbon dioxide from Earth's atmosphere; the researchers have already used it to capture carbon dioxide more efficiently and at a much lower cost than other methods.
