Faster-than-light “warp drives” may be theoretically possible, but they usually involve exotic physics well out of our reach. Now an astrophysicist has outlined a hypothetical design that could allow FTL travel using conventional physics. Source of Article
New research has demonstrated how odors evoke memories in the brain, in ways stronger than other senses. Using neuroimaging and intracranial electrophysiology the research shows how olfactory pathways communicate directly with the hippocampus. Source of Article
California's Orbital Assembly Corporation reckons it will soon have the solar system's first luxury space hotel open in orbit, offering spacewalks, Beyonce concerts and fine dining to space tourists at prices near US$5 million per three and a half days. Source of Article
A number of hearing aids are now able to amplify one person's voice while filtering out distracting background voices. Well, it turns out that female tree frogs are able to perform a similar task, in order to hear the mating calls of males. Source of Article
A new breakthrough could lead to a safe, effective and reversible male contraceptive pill, as a compound from traditional Chinese medicine has been shown in tests to render mice and monkeys temporarily infertile. Source of Article
We all know that bats locate prey in the dark using echolocation, but … is that really all there is to it? Scientists decided to get more details on the animals' hunting process, by equipping them with tiny wearable computers. Source of Article
Urinary tract infections are a common and painful infection that can be surprisingly persistent. Now, researchers have developed a vaccine that can be delivered via catheter to clear out the bacteria and prevent infections from recurring. Source of Article
NASA astronauts recently completed a seven-hour spacewalk to prepare the International Space Station for the arrival of a new set of solar panels that will help support the ageing array that’s been serving the station since December 2000. Source of Article
Scientists have made a breakthrough around how lithium-metal batteries function at ultra-low temperatures, building a version that relies on weak bonds in its electrolyte to offer unprecedented performance in the cold. Source of Article
Graphene has a lot of useful properties, but magnetism isn’t usually one of them. Now, researchers have managed to induce an “artificial magnetic texture” in graphene, which could have major implications for the emerging field of spintronics. Source of Article
