Fat tissue, for as much as it’s been vilified, is an incredibly complex and essential bodily organ involved in energy storage and hormone production, among other functions. Yet, modern lifestyles have led to a worldwide epidemic of obesity, and a corresponding increase in related conditions like type 2 diabetes and cardiovascular disease.

Researchers are attempting to uncover the basics of how fat tissue is structured and, specifically, inflammation associated with obesity, in the hopes of unlocking the connection between the accumulation of fat and poor health outcomes.

Toward Metropolitan Free-Space Quantum Networks

Towards metropolitan free-space quantum networks
Metropolitan entanglement-based free-space network. a) A standardized centrally located entanglement server (ES, black box) is streaming entangled photons into the network. Free-space channels are used to connect distant buildings and parts of a metropolitan area, while fiber connections may still be used in a complementary way, for example, to connect to offices within the central building. Each end user owns an application-specific quantum receiver subsystem (green boxes). b) The corresponding physical layer network topology. At the quantum communication layer, the network is a pairwise connected mesh, so that every end user can communicate with any other (not shown). c) A near-term extension possibility using several ESs and a central trusted node...

An unexpectedly high number of young stars has been identified in the direct vicinity of a supermassive black hole and water ice has been detected at the center of our galaxy.

An international team led by Dr Florian Peißker at the University of Cologne’s Institute of Astrophysics has analysed in detail a young star cluster in the immediate vicinity of the super massive black hole Sagittarius A* (Sgr A*) in the centre of our galaxy and showed that it is significantly younger than expected...

Swap Red Meat for Quorn Protein to Improve Heart Health and Reduce Waist Circumference, study finds

Swap red meat for Quorn protein to improve heart health and reduce waist circumference, study finds

People looking to reduce their cholesterol and trim fat from around their waist could try swapping meat for Quorn protein, according to the findings from a new study by Northumbria University, Newcastle, published in the European Journal of Nutrition, which saw positive effects in both areas in just two weeks.

Researchers from the University found that participants who ate Quorn products — the popular mycoprotein-based meat substitute — over just a two-week period, saw a significant 12% drop in ‘bad’ LDL cholesterol and a 7% fall in total cholesterol, compared to those who ate similar products made from red and processed meat. In addition, they also reduced their waist circumference by close to 1cm (0.95cm) on average over the 14 days.

Such a drop in total cholesterol levels cou...
