Engineers have introduced a new advanced energy harvesting system, capable of generating electricity by simply being attached to clothes, windows, and outer walls of a building. This new device is based on a temperature difference between the hot and cold sides. The temperature difference can be increased as high as 20.9 °C, which is much higher than the typical temperature differences of 1.5 to 4.1 °C of wearable thermoelectric generators driven by body heat...

Galaxy NGC 1068 can be seen in close-up in this view from NASA’s Hubble Space Telescope. This active black hole -shown as an illustration in the zoomed-in inset- is one of the most obscured known, as it is surrounded by extremely thick clouds of gas and dust that can be characterized using infrared and X-ray observations.

New research examines the material that obscures active galactic nuclei obtained from infrared and X-ray observations. Black holes appear to play a fundamental role in how galaxies evolve throughout their life during a phase in which they are active and consume material from the galaxy itself...

An international team of scientists from the Monash University (Melbourne, Australia), the Towson and Pittsburgh Universities (USA) and the Max Planck Institute for Astrophysics, has shed new light on the origins of the famous Tycho’s supernova. The research debunks the common view that Tycho’s supernova originated from a white dwarf, which had been slowly accreting matter from its companion in a binary system.

Type Ia supernovae (SNe Ia) serve as standard candles of modern observational cosmology; they also play a vital role in galactic chemical evolution. However, the origin of these gigantic cosmic explosions remains uncertain...

Some diabetes medicine reduce the risk of getting Parkinson´s disease by 35%. Copyright: Colourbox

A Norwegian study shows that the taking of diabetes medicine reduces the risk of getting Parkinson´s disease. Researchers at the Department of Clinical Medicine at the University of Bergen (UiB) have discovered that medical treatment against diabetes reduces the risk of getting Parkinson´s disease by 35%. “We have made an important discovery, which takes us a step further towards solving the Parkinson´s riddle,” says researcher Charalampos Tzoulis. He has lead the study together with researcher Kristoffer Haugarvoll at the same department.

Tzoulis says that the researchers have to do follow-up studies on the diabetes medicine to fully understand why it protects against Parkinson´s disease...
