To Infinity Cache and beyond?
If Big Navi does run with a 256-bit bus as some rumors suggest, cache could be the key to the graphics card’s performance.
Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity.
Now, a team of researchers at Columbia University and the University of Washington has discovered that a variety of exotic electronic states, including a rare form of magnetism, can arise in a three-layer graphene structure.
The findings appear in an article published Oct. 12 in Nature Physics.
Tesla is looking into moving “current and future vehicle programs” to steer-by-wire with a new motor, geartrain, and chassis team in Austin, Texas.
Over the last few months, we have been reporting on how Tesla plans to establish new teams in Austin that are not directly related to the new Gigafactory under construction.
For example, we previously reported on Tesla building a new video game and user interface team in Austin.
Researchers at the Institute of Industrial Science at the University of Tokyo sifted through experimental data to probe the possibility that supercooled water has a liquid-to-liquid phase transition between disordered and tetrahedrally structured forms. They found evidence of a critical point based on the cooperative formation of tetrahedra, and show its minor role in water’s anomalies. This work shows that water’s special qualities—which are essential for life—originate predominantly from the two-state feature.
Liquid water is indispensable for life as we know it, yet many of its properties do not conform with the way other fluids behave. Some of these anomalies, such as water’s maximum density at 4°C and its large heat capacity, have important implications for living organisms. The origin of these features has sparked fierce debates in the scientific community since the time of Röntgen.
Now, researchers at The University of Tokyo have utilized a two-state model that posits the dynamical coexistence of two types of molecular structures in liquid water. These are the familiar disordered normal-liquid structure and a locally favored tetrahedral structure. As with many other phase transitions, there may be a “critical point” at which the correlation between tetrahedra takes on a power-law form, which means there will no longer be any “typical” length scale.
Virtual reality software which allows researchers to ‘walk’ inside and analyse individual cells could be used to understand fundamental problems in biology and develop new treatments for disease.
The software, called vLUME, was created by scientists at the University of Cambridge and 3D image analysis software company Lume VR Ltd. It allows super-resolution microscopy data to be visualised and analysed in virtual reality, and can be used to study everything from individual proteins to entire cells. Details are published in the journal Nature Methods.
Super-resolution microscopy, which was awarded the Nobel Prize for Chemistry in 2014, makes it possible to obtain images at the nanoscale by using clever tricks of physics to get around the limits imposed by light diffraction. This has allowed researchers to observe molecular processes as they happen. However, a problem has been the lack of ways to visualise and analyse this data in three dimensions.
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals–dopamine and serotonin–are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
Furthermore, the neurochemicals appear to integrate people’s perceptions of the world with their actions, indicating dopamine and serotonin have far more expansive roles in the human nervous system than previously known.
Known as neuromodulators, dopamine and serotonin have traditionally been linked to reward processing–how good or how bad people perceive an outcome to be after taking an action.
Elon Musk, the CEO of SpaceX, has announced that his space internet project is ready for public use. The statement comes after SpaceX launched 60 Starlink satellites into low-Earth orbit last week, bringing the total number to almost 800.
Eventually, SpaceX plans to launch tens of thousands of Starlink satellites to create a blanket around the Earth capable of beaming high-speed broadband internet to 99% of the inhabited world.
The OEC need some VR sets next year.
Star Trek’s holodeck, that lets people physically interact with a virtual world could be a step closer thanks to a ‘universal law of touch’, discovered by British scientists.

Mankind has mastered the art of flight for well over a century, and the concept has become so normalized that we tend to take for granted this amazing accomplishment, but as advanced as modern airplanes are, we are still not much closer to developing a vehicle that can travel as well on land as it can in the air. The concept of a flying car has haunted engineers for decades, and companies such as Hyundai have dedicated some serious research and development to make this dream come true. But now an Italian upstart named Firenze has come up with a new and exciting concept that will be powered by the same electric motors that power the Tesla Model S.
