Irradiation using light in the blue spectra has proven to have powerful bacteria-killing ability in laboratory studies using human and animal tissues.  

In a Neuron paper,
Institute of Science and Technology Austria
post-doctoral fellow Alejandro Pernía-Andrade and Professor Peter Jonas outline the synaptic mechanisms underlying oscillations at the dentate gyrus, the main entrance of the hippocampus).

Building on that work, the researchers suggest a role for these oscillations in the coding of information by the dentate gyrus principal neurons. 

An international team has published a major list of celestial X-ray sources in the Astrophysical Journal - over 150,000 high-energy stars and galaxies.

Using the X-ray telescope on board the US/UK/Italian Swift satellite, the team analyzed eight years' worth of data to make the first Swift X-ray Point Source catalogue. In addition to providing the positions of almost a hundred thousand previously unknown X-ray sources, the team have also analyzed the X-ray variability and X-ray colors of the sources in order to help to understand the origin of their emission, and to help in the classification of rare and exotic objects.

All of the data, including light curves and spectra are available online.

Astronomers recently took precise measurements of the closest pair of failed stars to the Sun, the binary brown dwarf system WISE J104915.57-531906.1, and the results suggest that the system harbors a third, planetary-mass object.

Failed stars are known as brown dwarfs and have a mass below 8% of the mass of the Sun—not massive enough to burn hydrogen in their centers. This particular system, Luhman 16AB, was discovered earlier this year and is only 6.6 light-years away.

Patients in a vegetative state are awake, breathe on their own, and seem to go in and out of sleep, but they don't respond to what is happening around them and exhibit no signs of conscious awareness.

Do they even know if friends and family are even there?

A functional magnetic resonance imaging (fMRI) study has shown that the brains of patients in a vegetative state emotionally react to photographs of people they know personally as though they recognize them.

Hunters are often regarded as the enemy by animal activists but in reality the opposite is true; legal hunting helps sustain populations, even trophy hunting.  

Trophy hunting occurs in 9 of the 28 African countries that have wild populations of lions. Hunting is legal in these countries but quotas are set to restrict the numbers of lions that can be killed.
