The Sci Tech World

The new fibers were developed through a collaboration among material scientists, chemists, biologists, and other specialists. The results are reported in the journal Nature Neuroscience, in a paper by Seongjun Park, an MIT graduate student; Polina Anikeeva, the Class of 1942 Career Development Professor in the Department of Materials Science and Engineering; Yoel Fink, a professor in the departments of Materials Science and Engineering, and Electrical Engineering and Computer Science; Gloria Choi, the Samuel A. Goldblith Career Development Professor in the Department of Brain and Cognitive Sciences, and 10 others at MIT and elsewhere. The fibers are designed to mimic the softness and flexibility of brain tissue. This could make it possible to leave implants in place and have them retain their functions over much longer periods than is currently possible with typical stiff, metallic fibers, thus enabling much more extensive data collection. For example, in tests with lab mice, the resea...

Last year, neuroscientists used a classic branch of maths in a totally new way to peer into the structure of our brains. What they discovered is that the brain is full of multi-dimensional geometrical structures operating in as many as 11 dimensions. We're used to thinking of the world from a 3-D perspective, so this may sound a bit tricky, but the results of this study could be the next major step in understanding the fabric of the human brain - the most complex structure we know of. This brain model was produced by a team of researchers from the Blue Brain Project, a Swiss research initiative devoted to building a supercomputer-powered reconstruction of the human brain. The team used algebraic topology, a branch of mathematics used to describe the properties of objects and spaces regardless of how they change shape. They found that groups of neurons connect into 'cliques', and that the number of neurons in a clique would lead to its size as a high-dimensional geometric ob...

Warp Speed Travel Is Theoretically Possible, Says Astrophysicist Yesterday a Youtuber's account got hacked, and this video was uploaded that contains footage of the Black Knight Satellite being shot down. The weapon that was used was an anti-matter warhead according to the Wikileaks documents. It's unclear who gave the order to bring down this extraterrestrial craft. In the video, we also catch a glimpse of the secret aircraft that carried out the attack. After the impact, several escape pods are launched back into space. In this stage, we can only speculate on the reason why the Black Knight Satellite was shot down. Was it about to signal it's creators to come to earth? Was the Black Knight Satellite regarding the boundaries of space for humans that have the ambition of interplanetary traveling?

Sean Carroll is a physicist at Caltech. His research includes theoretical physics and astrophysics, especially cosmology, field theory, and gravitation. He has published several research papers dark matter and dark energy, modified gravity, violations of Lorentz invariance, extra dimensions, topological defects, cosmic microwave background anisotropies, causality violation, black holes, and the cosmological constant problem. He is currently focused on origin of the universe and the arrow of time, including the roles of inflation, baby universes, and quantum gravity. In his recent video by Techinsider, he explains what existed before Big Bang and it actually means. So watch and learn:

Sure, claiming the Moon is artificial might sound crazy, but why does it ring like a bell when struck ? Previous expeditions to the Moon have brought back considerable amount of information, but our planet’s natural satellite still remains mostly a mistery for researchers. The first man ever invested by NASA to head the Commission of Lunar Exploration, Dr. Jastrow, referred to the Moon as “ the Rosetta stone of the planets. Many UFOlogists are convinced that the Moon, who everybody believes to be a natural satellite, was in fact built by a more advanced civilization as a study base where they could document the behavior of our species. Others believe the aliens aren’t that interested in our society as they don’t understand intra-racial violence, so the Moon serves as a simple watchtower that would let them know if mankind would ever try to leave Earth and travel through space. Moderate theorists say its body is covered by a rocky layer, which could measure more than 3 miles from the su...

Okay, time to stop everything and nut out a brain teaser: if Earth is spinning to the east at 1,180 km/h (733 mph), and we're in a plane flying west, shouldn't we get to our destination quicker, seeing as it's literally spinning towards us?The short answer is no, because our plane is also affected by Earth's spin, which means we're spinning away from our destination while our destination is spinning towards us. Confused yet? Don't worry, MinutePhysics has the slightly-less-short answer (it's still MinutePhysics, after all) to this dizzying conundrum. While Earth itself is spinning about 1,180 km/h to the east, the ground and everything on it are travelling even faster - at about 1,670 km/h (1,037 mph). Even the air above the ground is travelling at around this speed in an easterly direction. So for an aeroplane to get anywhere at all, it has to be moving relative to the ground. Say it's travelling at 160 km/h (100 mph) - because it's already moving a...

Mathematical equations are, no doubt, useful but several are quite beautiful. And many scientists confess they are often fond of specific formulas not just for their purpose, but for their arrangement, and the humble, poetic truths they comprise. Here are 7 of the the world's most beautiful equations. General relativity The equation below was presented by Einstein as part of his revolutionary general theory of relativity in 1915. The theory transformed how researchers understood gravity by labelling the force as a bending of the fabric of space and time. Astrophysicist Mario Livio from Space Telescope Science Institute says "It is still amazing to me that one such mathematical equation can describe what space-time is all about. All of Einstein's true genius is embodied in this equation." Livio explained "The right-hand side of this equation describes the energy contents of our universe (including the 'dark energy' that propels the current cosmic accelerat...
