Despite years of efforts, malaria remains a major health problem. The mosquito-borne parasitic disease sickens more than 200 million people every year and kills more than 400000, many of whom are children.

For the first time, scientists have shown that a new kind of genetic engineering can crash populations of malaria-spreading mosquitoes.

In the landmark study, published Wednesday in the journal Nature Communications, researchers placed the genetically modified mosquitoes in a special laboratory that simulated the conditions in sub-Saharan Africa, where they spread the deadly disease.

Several Clostridium species enriched in children with autism closely interacted with each other and formed a connected group. Clostridia species have been linked with autism via the production of clostridial toxins which can damage the central nervous system, point out the researchers.

Significantly fewer gut bugs linked to neurotransmitter activity.

Children with autism seem to have a distinctive and underdeveloped range and volume of gut bacteria (microbiome) that isn’t related to their diet, suggests a small study published online in the journal Gut.

And it did so on its own without a tether.

Cassie, a bipedal robot that’s all legs, has successfully run five kilometers on a single charge, all without having a tether. The machine serves as the basis for Agility Robotics’ delivery robot Digit, as TechCrunch notes, though you may also remember it for “blindly” navigating a set of stairs. Oregon State University engineers were able to train Cassie in a simulator to enable it to go up and down a flight of stairs without the use of cameras or LIDAR. Now, engineers from the same team were able to train Cassie to run using a deep reinforcement learning algorithm.

Push materials to their limits, and strange things can occur – such as the discovery of a previously unknown phase of liquid, which has been reported by scientists looking at the development of super-thin, high-density glass.

These types of glass are used in a variety of ways, including in OLED displays and optical fibers, but they can have stability problems. It’s through an effort to tackle those problems that this different type of material has come to light.

Crucially, the newly discovered liquid phase promises thin glass that’s more stable and denser than the materials that have come before – a progression that could open up different ways of using the glass, and even completely new types of devices.

Researchers at the National Aeronautics and Space Administration (NASA) recently announced that it is using artificial intelligence to calibrate images of the Sun.

NASA launched its Solar Dynamics Observatory (SDO) back in early 2010 to conduct research and capture high-definition images of the Sun.

The new artificial intelligence-powered technology is now helping scientists to precisely calibrate captured images at a quick pace in order to generate accurate, usable data. NASA uses the Atmospheric Imagery Assembly (AIA) present at the SDO to capture the Sun’s images across various wavelengths of ultraviolet light every 12 seconds.

With around two weeks still remaining in its crowdfunding campaign, Buck Institute incubated start-up Gerostate Alpha has cruised through its minimum funding target of $300000. The company also revealed that Longevitytech.fund has joined the round as a lead investor, bringing the total investment in the company to more than $500000 so far.

“At Longevitytech.fund, we invest in start-ups focused on aging that will materially ‘move the needle,’” says the investment firm’s managing partner, Petr Sramek. “The team at Gerostate Alpha is poised to do just that in the coming years, and we are very excited to partner with them for the long haul.”

Longevity. Technology: For early stage biotech companies, particularly those targeting aging, securing funding is a constant challenge. Gerostate Alpha is “testing the water” by exploring crowdfunding as another financing option, and seems to have had some success with it. We caught up with the company’s co-founders Simon Melov and Mark Lucanic to find out more.

How true?

However, after subsequent reporting, I discovered a kernel of truth to the rumors of stainless steel and Blue Origin rockets. Three sources have confirmed to Ars that Blue Origin has started working on a project to develop a fully reusable upper stage for New Glenn, which may potentially use stainless steel propellant tanks.

The primary goal of this change is to bring down the overall launch cost of the New Glenn rocket. The vehicle’s large upper stage, with a 7-meter diameter and two BE-3U engines, is costly, and Blue Origin founder Jeff Bezos is looking for ways to make the overall rocket more economical.

A team of researchers at ARM Inc., has developed a 32-bit microprocessor on a flexible base which the company claims could pave the way to fully flexible smart integrated systems. In their paper published in the journal Nature, the group describes how they used metal−oxide thin-film transistors along with a type of plastic to create their chip and outline ways they believe it could be used.

Microprocessors power a wide range of products, but what they all have in common is their stiffness. Almost all of them are made using silicon wafers, which means that they have to be hard and flat. This inability to bend, the researchers with this new effort contend, is what is preventing the development of products such as smart clothes, smart labels on foods, packaging and even paper products. To meet that need, the team has created what they describe as the PlasticARM—a RISC-based 32-bit microprocessor set on a flexible base. In addition to its flexibility, the new technique allows for printing a microprocessor onto many types of materials, all at low cost.

To create their bendy microprocessor, the researchers teamed with a group at PragmatIC Semiconductor to create a bendable version of the Cortex M0+ microprocessor, which was chosen for its simplicity and small size. To make their chip, (which includes ROM, RAM and interconnections) the team used amorphous silicon fabricated (in the form of metal-oxide thin-film transistors) onto flexible polymers.

Electron-positron pair generation from nonlinear quantum electrodynamics is predicted at high intensities that are, so far, beyond experimental capabilities. Here, simulations predict a high yield of positrons can be obtained from gamma-gamma photon collisions in the linear regime, using counter-propagating pulses and a microstructured target.
