A Harvard study says encryption does not fullfill securuty measures
A new study, from Harvard´s Berkman Center for Internet and Society, now suggests claims that criminals were "going dark" are overblown. The study was authored by a panel of security experts, which included Matthew G. Olsen, former director of the National Counterterrorism Center under the Obama administration, and Bruce Schneier, a well-known cryptographer.

Antarctic fungi survive Martian conditions on the International Space Station
European scientists have gathered tiny fungi that take shelter in Antarctic rocks and sent them to the International Space Station. After 18 months on board in conditions similar to those on Mars, more than 60% of their cells remained intact, with stable DNA. The results provide new information for the search for life on the red planet. Lichens from the Sierra de Gredos (Spain) and the Alps (Austria) also travelled into space for the same experiment.

Google builds a computer that can beat expert player at the board game Go
Google achieves one of the long-standing "grand challenges" of AI by building a computer that can beat expert players at the board game Go. Artificial intelligence researchers at Google DeepMind have taught a computer program the ancient game of Go, which has long been considered the most challenging game for an an artificial intelligence to learn.

With luminescent proteins
German and Spanish Scientists discovered a way to create a BioLEDs
Scientists from Germany and Spain have discovered a way to create a BioLED by packaging luminescent proteins in the form of rubber. This innovative device gives off a white light which is created by equal parts of blue, green and red rubber layers covering one LED, thus rendering the same effect as with traditional inorganic LEDs but at a lower cost.

International Union of Pure and Applied Chemistry
Four new elements added to periodic table
The International Union of Pure and Applied Chemistry (IUPAC), the US-based global authority on chemistry, had announced that the table´s seventh row was now complete. Elements 113, 115, 117 and 118 were added to the table - its first update since 2011 - and will be named in the coming months by the scientific teams who discovered them.

Names from several cultures
International contest renames 14 stars
Thanks to a worldwide vote, 14 stars in our universe and 31 exoplanets that orbit them now have new names. The International Astronomical Union — the reigning authority on naming celestial bodies throughout the cosmos — released the winners of its NameExoWorlds contest today. More than half a million votes helped to decide the winners, which include such inventive titles as Chalawan, Cervantes, and Helvetios.

Beginnings of our galaxy
A ´ghost from the past´ recalls the infancy of the Milky Way
When our galaxy was born, around 13,000 million years ago, a plethora of clusters containing millions of stars emerged. But over time, they have been disappearing. However, hidden behind younger stars that were formed later, some old and dying star clusters remain, such as the so-called E 3. European astronomers have now studied this testimony to the beginnings of our galaxy.

Nasa reveals solar winds stripped Mars´ atmosphere
NASA researchers have just announced that Mars´ once rich atmosphere was stripped away by solar winds in the early days of the Solar System, causing the planet to dry out. This announcement was just the latest in a series of major discoveries about the Red Planet, including the strongest evidence yet of flowing, liquid water on the surface, reported last September.

Cardiff University-led research
Past earthquakes play a role in future landslides, research suggests
The likelihood of an area experiencing a potentially devastating landslide could be influenced by its previous exposure to earthquakes many decades earlier. This is according to new research led by Cardiff University showing that areas which have experienced strong earthquakes in the past were more likely to produce landslides when a second earthquake hit later on.

Clothes in animations
Disney researchers use multigrid method to speed up cloth simulation
The technique enables more realistic look, behavior of cloth in animation. Simulating the behavior of clothing and other fabrics in animated films requires animators to make tradeoffs between a realistic look and a reasonable amount of computing time. Researchers at Walt Disney Animation Studios now have developed a method that can shift the balance toward greater realism.

 ´Watchtower Class´
Signs of acid fog found on Mars
Planetary scientist Shoshanna Cole has pieced together a compelling story about how acidic vapors may have eaten at the rocks in a 100-acre area on Husband Hill in the Columbia Hills of Gusev Crater on Mars. She used a variety of data gathered by multiple instruments on the 2003 Mars Exploration Rover Spirit to tease out information from exposures of the ancient bedrock.

Researchers at NYU
Study reveals how brain multitasks
Findings help explain how the brain pays attention to what´s important and how neural circuits may be ´broken´ in attention-deficit disorders. Researchers at NYU Langone Medical Center say they have added to evidence that a shell-shaped region in the center of the mammalian brain, known as the thalamic reticular nucleus or TRN, is likely responsible for the ability to routinely and seamlessly multitask.
