Flashes of Light on Dark Matter

On the left side the cosmic web in the standard cold scenario, on the right side how it would look like in the Fuzzy Dark Matter model. The curved lines in both panels show how the absorption by the neutral hydrogen in the cosmic web behaves in the two models. The right curve does not agree with the data, while the left one does.

Engineers explore ways to sample and identify living microbes in the outer solar system. Digital holographic microscopy, which uses lasers to record 3D images, may be our best bet for spotting extraterrestrial microbes. No probe since NASA’s Viking program in the late 1970s has explicitly searched for extraterrestrial life – that is, for actual living organisms. Rather, the focus has been on finding water. Enceladus has a lot of water – an ocean’s worth, hidden beneath an icy shell that coats the entire surface...

Why Sugary Drinks and Protein-Rich Meals don’t go well Together

Having a sugar-sweetened drink with a high-protein meal may negatively affect energy balance, alter food preferences and cause the body to store more fat, according to a study published in the open access journal BMC Nutrition...

How Physical Exercise Prevents Dementia

Numerous studies have shown that physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age. Gerontologists and sports physicians at Goethe University Frankfurt have examined the effects of regular exercise on brain metabolism and memory of 60 participants aged between 65 and 85 in a randomised controlled trial. Their conclusion: regular physical exercise not only enhances fitness but also has a positive impact on brain metabolism.

As the researchers report in the current issue of the medical journal Translational Psychiatry, they thoroughly examined all the participants in the SMART study (Sport an...
