An international team of researchers led by the University of Tokyo has discovered a new material which, when rolled into a nanotube, generates an electric current if exposed to light. If magnified and scaled up, say the scientists, the technology could be used in future high-efficiency solar devices.
The answer to halting triple-negative breast cancer, the deadliest of all breast cancers, may have just been discovered by researchers from Boston Children’s Hospital.
A CRISPR gene-editing system — all encompassed into a nanogel capsule, that is then injected into the affected person’s body — is the potential antidote to stopping the growth of triple-negative breast cancer tumors.

It’s the most complex integration of carbon nanotube-based CMOS logic so far, with nearly 15,000 transistors, and it was done using technologies that have already been proven to work in a commercial chip-manufacturing facility. The processor, called RV16X-NANO, is a milestone in the development of beyond-silicon technologies, its inventors say.
Unlike silicon transistors, nanotube devices can easily be made in multiple layers with dense 3D interconnections. The Defense Advanced Research Projects Agency is hoping this 3D aspect will lead to commercial carbon nanotube (CNT) chips with the performance of today’s cutting-edge silicon but without the high design and manufacturing cost.
Some of the same researchers created a modest one-bit, 178-transistor processor back in 2013. In contrast, the new one, which is based on the open source RISC-V instruction set, is capable of working with 16-bit data and 32-bit instructions. Naturally, the team, led by MIT assistant professor Max Shulaker, tested the chip by running a version of the obligatory “Hello, World!” program. They reported the achievement this week in Nature.
A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing can escape, not even light. These cosmic phenomena are said to form when massive stars collapse at the end of their life cycle. Then, they can continue to grow by absorbing mass from their surroundings, engulfing stars in their path and merging with other black holes.

WASHINGTON — SpaceX plans to build facilities at the Kennedy Space Center’s Launch Complex 39A for launches and, eventually, landings of its next-generation launch vehicle, according to a newly released report.
An environment assessment prepared by SpaceX, and released by NASA Aug. 1, discusses plans to develop additional facilities at LC-39A, which currently hosts Falcon 9 and Falcon Heavy launches, for use by the company’s Starship vehicle and its Super Heavy booster.
The plans outlined in the document call for the construction of a new launch mount at the complex near the existing one used by the Falcon 9 and Heavy. The modifications to the pad would also include a tank farm for the methane fuel used by the Raptor engines that power Starship and Super Heavy.

Contact lenses capable of recording video and taking pictures could one day become a reality after Samsung was granted a patent in the US to develop the technology.
The lenses feature motion sensors, which means that wearers could control devices with their eye movements and potentially give commands to their devices remotely when blinking or using their peripheral vision.
