A research team from Oxford University have shown how different colours of light could affect our ability to sleep.

The researchers, led by Dr Stuart Peirson from Oxford's Sleep and Circadian Neuroscience Institute were aiming to understand why exposing mice to bright light caused two - physically incompatible - responses.

Dr Peirson explained: 'When we expose mice to light during the night, it causes them to fall asleep. Yet, at the same time, it also increases levels of corticosterone, a stress hormone produced by the adrenal gland that causes arousal - wakefulness. We wanted to understand how these two effects were related and how they were linked to a blue light-sensitive pigment called melanopsin, known to play a key role in setting our body clock.'

New research combining eight large child care studies reveals that preschools prepare children to succeed academically when teachers provide higher quality instruction.

Margaret Burchinal, senior scientist at the Frank Porter Graham Child Development Institute at the University of North Carolina at Chapel Hill, led a research team whose findings have groundbreaking implications for publicly-funded early care and education. They found as the overall quality of instruction in preschool classrooms increases, children experience better outcomes across a range of skills, but the needle only moves on language and reading skills when instructional quality is at or above a threshold.

Researchers at the National Institute of Neurological Disorders and Stroke have discovered that boosting the transport of mitochondria along neuronal axons enhances the ability of mouse nerve cells to repair themselves after injury. The study, "Facilitation of axon regeneration by enhancing mitochondrial transport and rescuing energy deficits," which has been published in The Journal of Cell Biology, suggests potential new strategies to stimulate the regrowth of human neurons damaged by injury or disease.

June 7, 2016 - Adding to previous evidence, a study based on a statewide cancer database shows no increase in cancer risk in patients undergoing spinal fusion surgery with the bone-promoting growth factor recombinant human bone morphogenetic protein (rhBMP). The study appears in Spine, published by Wolters Kluwer.

The International Union of Pure and Applied Chemistry (IUPAC) opened a public comment period Wednesday for the recommended names of elements 115, 117 and 118.

Lawrence Livermore National Laboratory and the Joint Institute for Nuclear Research in Dubna, Russia (JINR) were credited late last year for discovering elements 115 and 118. LLNL, JINR, Oak Ridge National Laboratory (ORNL), Vanderbilt University and the University of Nevada, Las Vegas were credited with the discovery of element 117.

Moscovium (Mc) is provisionally recommended for element 115 in recognition of the Moscow region and honoring the ancient Russian land that is home to JINR. Moscow is the capital of the region.

ANN ARBOR, Mich. - Researchers at the University of Michigan have identified a promising new compound for targeting one of the most aggressive types of breast cancer.

The compound, currently called UM-164, goes after a kinase known to play a role in the growth and spread of triple-negative breast cancer. UM-164 blocks the kinase c-Src and inhibits another pathway, p38, involved in this subtype. The researchers also found that the compound had very few side effects in mice.

In treating diseases with drugs, dosing is critical; too little is ineffective, while too much can be lethal. Colorado State University's Brad Reisfeld takes a mathematical approach to achieving optimal dosing for various drugs.

Publishing earlier this week in the American Society for Microbiology's Antimicrobial Agents and Chemotherapy, Reisfeld, associate professor in the Department of Chemical and Biological Engineering and a faculty member in the School of Biomedical Engineering, has described a new computational model for optimizing dosing for the drug Rifapentine.

Installing a microgrid, such as a cooperative of power generators and power consumers operating in a coordinated system, within a regulated electricity market, will not work any better than the type of regulated de-regulation that led to California having utility rates 50 percent higher than other states.

It can work, it just depends on how heavily things are regulated. Microgrids are touted as hybrid alternatives to smooth out kinks in existing electricity networks. Wealthy elites with electric cars, for example, believe they are using no fossil fuels, without factoring in that each charger is equivalent in load to a whole new house on the grid, with power draws from nuclear or coal or natural gas just the same.

For what seems like decades, it has been open season on scientists and corporations by environmental non-profit corporations and the PR groups they fund to be their hatchet men, like SourceWatch and Mother Jones. Libel? No problem, Lisa Graves at SourceWatch will do it. Spinning stolen funding proposals provided by a fired employee as actual conspiracy events? Mother Jones will oblige.

A few years ago, there were concerns about Dengue in Florida. This plight on humanity is carried by a small number of mosquitoes that have no ecological value of any kind, they are just disease carriers that have somehow survived evolution. 

Pesticides obviously work, DDT has been killing the bugs that carry malaria for 70 years, but a more targeted approach is making sure they can't viably reproduce - a genetically modified mosquito does that quite well, but an activist mom, funded by environmentalists, whipped the public into frenzy. Science rationally showed that the arguments were hype, not science.
