Biochemists discover new insights into what may go awry in brains of Alzheimer's patientsThree decades of research on Alzheimer's disease have not produced major treatment advances for patients. Researchers now report new insights that may lead to progress in fighting the devastating disease. They discovered beta amyloid has a specific amino acid that can form a kink, like a kink in a garden hose, creating a harmful molecular zipper and leading to the death of neurons.Optic nerve stimulation to aid the blindScientists are investigating new ways to provide visual signals to the blind by directly stimulating the optic nerve. Their preliminary study uses a new type of neural electrode and provides distinct signals.Heat shield just 10 atoms thick to protect electronic devicesAtomically thin materials could create heat-shields for cell phones or laptops that would protect people and temperature-sensitive components and make future electronic gadgets even more compact.Materials that can revolutionize how light is harnessed for solar energyScientists have designed organic molecules capable of generating two excitons per photon of light, a process called singlet fission. The excitons can live for much longer than those generated from their inorganic counterparts, which leads to an amplification of electricity generated per photon that is absorbed by a solar cell.Type of brain cell involved in stuttering identifiedResearchers believe that stuttering -- a potentially lifelong and debilitating speech disorder -- stems from problems with the circuits in the brain that control speech, but precisely how and where these problems occur is unknown. Using a mouse model of stuttering, scientists report that a loss of cells in the brain called astrocytes are associated with stuttering. The mice had been engineered with a human gene mutation previously linked to stuttering. The study offers insights into the neurological deficits associated with stuttering.Insomnia tied to higher risk of heart disease and strokeData from more than a million people found that genetic liability to insomnia may increase the risk of coronary artery disease, heart failure and stroke. Among types of ischemic stroke, genetic liability to insomnia was primarily associated with an increased risk of large artery stroke.New molecule could help improve heart attack recoveryReparative medicine scientists have discovered a new compound that could shield heart tissue before a heart attack, as well as preserve healthy cells when administered after a heart attack.Shedding light on how the human eye perceives brightnessScientists are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated their crucial role in the perception of visual environment. This ushers in a new understanding of the biology of the eye and how visual information is processed.

What, exactly, is the inside of a neutron star like? A neutron star is what remains after a massive star goes supernova. It’s a tightly-packed, ultra-dense body made of—you guessed it—neutrons. Actually, that’s not absolutely true. Mathematical models show that neutron stars are made up of layers, and in those layers there are things other …

A space cocktail of science, bubbles and sounds
The International Space Station was again the stage for novel European science and routine operations during the first half of August. Plenty of action in the form of bubbles and sounds added to the mix in the run-up to a spacewalk and the comings and goings of visiting vehicles.To boldly go, again
The award-winning Space Rocks returns to the indigo at The O2 in London on 21 September for another celebration of space science and engineering, along with the art, music and science fiction inspired by it, presented by Twin V Ltd in association with ESA.The first DJ in space
ESA astronaut Luca Parmitano made space (and music) history on 13 August when he broadcast the first DJ music set from orbit, performing to an audience of over 3000 people as part of the BigCityBeats WORLD CLUB DOME Cruise Edition.Dark meets light on Mars
ESA’s Mars Express has captured the cosmic contrast of Terra Cimmeria, a region in the southern highlands of Mars marked by impact craters, water-carved valleys, and sand and dust in numerous chocolate and caramel hues.EDRS-C successfully launched
The second satellite to join the constellation that forms the European Data Relay System (EDRS) has been successfully launched.
The satellite was launched on board an Ariane 5 from Europe’s Spaceport in Kourou, French Guiana, on 6 August at 21:30 CEST (19:30 UTC).Two weeks of science and Beyond
Over two weeks have flown by since ESA astronaut Luca Parmitano was launched to the International Space Station for his second six-month stay in orbit. His arrival, alongside NASA astronaut Andrew Morgan and Roscosmos Soyuz commander Alexander Skvortsov, boosted the Station’s population to six and the crew has been busy ever since – performing a wide range of science in space.CryoSat conquers ice on Arctic lakes
The rapidly changing climate in the Arctic is not only linked to melting glaciers and declining sea ice, but also to thinning ice on lakes. The presence of lake ice can be easily monitored by imaging sensors and standard satellite observations, but now adding to its list of achievements, CryoSat can be used to measure the thickness of lake ice – another indicator of climate change.Asteroid's surprise close approach illustrates need for more eyes on the sky
On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon.
