Calculations find a flaw in the firewall argument
Black holes aren’t surrounded by a burning ring of fire after all, suggests new research.
Some physicists have believed in a “firewall” around the perimeter of a black hole that would incinerate anything sucked into its powerful gravitational pull. (more…)
Forscher entwickeln eine Kodierung, die Patienten ein natürlicheres Fühlen und Bewegen ermöglicht
Prothesen nicht wie einen Fremdkörper, sondern wie einen natürlichen Arm fühlen und bewegen – diesem Ziel ist ein internationales Forschungsteam um den Freiburger Mikrosystemtechniker Prof. Dr. Thomas Stieglitz ein Schritt näher gekommen. (more…)
ANN ARBOR — A sudden loss of wealth in middle or old age can be financially devastating—and fatal.
According to a University of Michigan study, adults in their 50s and older who suffer a catastrophic loss of wealth have a 50-percent higher risk of dying than those who do not have such loss. The effect can last for two decades, and whether participants are very wealthy or have only modest savings makes no difference. (more…)
Die Quantentheorie bildet die Grundlage der modernen Physik. Eine konsistente quantenmechanische Theorie der Gravitation bleibt trotz intensiver Bemühungen eines der großen offenen Probleme der theoretischen Physik. Der Kern des Problems besteht darin, dass auch die Raumzeit eine Quantenstruktur aufweisen muss, für die erst geeignete mathematische Modelle und Theorien entwickelt werden müssen. (more…)
The complex properties of water and ice are not well understood but a team from UCL and the ISIS Neutron and Muon Source have revealed new information about a phase of ice called ‘ice II’. (more…)
UA researchers are calling for a collective approach to a host of emerging ethical issues in the rapidly changing technological world, where today there are more questions than answers. (more…)
Findings could shed light on human health concerns and autism
COLUMBIA, Mo. – Past studies have shown that biparental care of offspring can be affected negatively when females and males are exposed to bisphenol A (BPA); however, previous studies have not characterized how long-term effects of BPA exposure in grandmothers and grandfathers might affect offspring communication ability.

Scientists demonstrate how organic dyes work as antennas to help harness, convert light
An international team of scientists has demonstrated a breakthrough in the design and function of nanoparticles that could make solar panels more efficient by converting light usually missed by solar cells into usable energy. (more…)
