Russia has lost its long-held monopoly as the only country able to ferry astronauts to the International Space Station following the flawless manned launch by US company SpaceX.

The Russian space agency congratulated the United States and Elon Musk’s SpaceX on the first crewed flight ever by a private company, but experts said the launch should be a wakeup call for Roscosmos.

“The success of the mission will provide us with additional opportunities that will benefit the whole international programme,” cosmonaut Sergei Krikalev, Roscosmos executive director for crewed space programmes, said in a brief video address.

VIENNA — We all know that one person who can eat whatever they like and never gain a pound. Ice cream at 2 in the morning? Bring it on. A third, or fourth, slice of pizza? Sure, why not. For the rest of us, the genetic perks that these individuals enjoy can be frustrating to say the least. Now, a groundbreaking new international study appears to have zeroed in on the so-called “skinny gene” that help keep such individuals thin.

Scientists from Austria, Canada, and Estonia say that lower, or deficient, levels of the gene Anaplastic Lymphoma Kinase (ALK) are significantly linked to skinniness and bodily resistance to weight gain.

Most research projects focusing on weight loss and gain search for genes that cause obesity. This study is novel due to the fact that it focuses specifically for a gene linked to thinness instead.

EL PUEBLO SE ESTÁ DESPERTANDO🇦🇷💪🏻

Presidente, el pueblo se cansó de su falta de empatía, ya no cree en usted ni en la “cuarentena”.

Miles de comercios y pymes se están fundiendo, la mayoría no recibió ayuda del gobierno.

Discovering and optimizing commercially viable materials for clean energy applications typically takes more than a decade. Self-driving laboratories that iteratively design, execute, and learn from materials science experiments in a fully autonomous loop present an opportunity to accelerate this research process. We report here a modular robotic platform driven by a model-based optimization algorithm capable of autonomously optimizing the optical and electronic properties of thin-film materials by modifying the film composition and processing conditions. We demonstrate the power of this platform by using it to maximize the hole mobility of organic hole transport materials commonly used in perovskite solar cells and consumer electronics. This demonstration highlights the possibilities of using autonomous laboratories to discover organic and inorganic materials relevant to materials sciences and clean energy technologies.

Optimizing the properties of thin films is time intensive because of the large number of compositional, deposition, and processing parameters available (1, 2). These parameters are often correlated and can have a profound effect on the structure and physical properties of the film and any adjacent layers present in a device. There exist few computational tools for predicting the properties of materials with compositional and structural disorder, and thus, the materials discovery process still relies heavily on empirical data. High-throughput experimentation (HTE) is an established method for sampling a large parameter space (4, 5), but it is still nearly impossible to sample the full set of combinatorial parameters available for thin films. Parallelized methodologies are also constrained by the experimental techniques that can be used effectively in practice.

Study co-led by Berkeley Lab reveals how wavelike plasmons could power up a new class of sensing and photochemical technologies at the nanoscale.

Wavelike, collective oscillations of electrons known as “plasmons” are very important for determining the optical and electronic properties of metals.

In atomically thin 2D materials, plasmons have an energy that is more useful for applications, including sensors and communication devices, than plasmons found in bulk metals. But determining how long plasmons live and whether their energy and other properties can be controlled at the nanoscale (billionths of a meter) has eluded many.

Researchers at Universidad Carlos III de Madrid (UC3M) have patented a new spatial plasma-fueled engine capable of satellite and spacecraft propulsion, with magnetic field geometry and configuration that would minimize losses on walls and their erosion, thereby resolving issues of efficiency, durability, and operating restrictions of engines that are currently in orbit.

Waves, whether they are light waves, sound waves, or any other kind, travel in the same manner in forward and reverse directions—this is known as the principle of reciprocity. If we could route waves in one direction only—breaking reciprocity—we could transform a number of applications important in our daily lives. Breaking reciprocity would allow us to build novel “one-way” components such as circulators and isolators that enable two-way communication, which could double the data capacity of today’s wireless networks. These components are essential to quantum computers, where one wants to read a qubit without disturbing it. They are also critical to radar systems, whether in self-driving cars or those used by the military.

A team led by Harish Krishnaswamy, professor of electrical engineering, is the first to build a high-performance non-reciprocal device on a compact chip with a performance 25 times better than previous work. Power handling is one of the most important metrics for these circulators and Krishnaswamy’s new chip can handle several watts of power, enough for cellphone transmitters that put out a watt or so of power. The new chip was the leading performer in a DARPA SPAR (Signal Processing at RF) program to miniaturize these devices and improve performance metrics. Krishnaswamy’s group was the only one to integrate these non-reciprocal devices on a compact chip and also demonstrate performance metrics that were orders of magnitude superior to prior work. The study was presented in a paper at the IEEE International Solid-State Circuits Conference in February 2020, and published May 4, 2020, in Nature Electronics.

“For these circulators to be used in practical applications, they need to be able to handle watts of power without breaking a sweat,” says Krishnaswamy, whose research focuses on developing integrated electronic technologies for new high-frequency wireless applications. “Our earlier work performed at a rate 25 times lower than this new one—our 2017 device was an exciting scientific curiosity but it was not ready for prime time. Now we’ve figured out how to build these one-way devices in a compact chip, thus enabling them to become small, low cost, and widespread. This will transform all kinds of electronic applications, from VR headsets to 5G cellular networks to quantum computers.”

A flaw in a Bluetooth protocol is leaving millions of devices vulnerable to attacks, according to a study released by a Swiss research institute.

The vulnerability, called Bluetooth Impersonation AttackS (BIAS), allows an intrusion by an attacker posing as a previously trusted Bluetooth device.

“In this paper, we demonstrate that the Bluetooth standard contains vulnerabilities enabling an attacker to impersonate a device and to establish a secure connection with a victim, without possessing the long term key shared by the impersonated device and the victim,” researchers at the Swiss Federal Institute of Technology Lausanne said in their report.
