The new type of catalyst, known as a biohybrid photocatalyst, contains a light-harvesting protein that absorbs light and transfers the energy to a metal-containing catalyst. This catalyst then uses the energy to perform reactions that could be useful for synthesizing pharmaceuticals or converting waste products into biofuels or other useful compounds.

“By replacing harmful conditions and reagents with light, photocatalysis can make pharmaceutical, agrochemical, and fuel synthesis more efficient and environmentally compatible,” says Gabriela Schlau-Cohen, an associate professor of chemistry at MIT and the senior author of the new study.

REE Automotive has revealed Leopard, its autonomous concept vehicle based on a brand new ultra-modular EV platform design. The full-scale concept is intended for customers, including last-mile autonomous and electric delivery companies, delivery fleet operators, e-retailers, and technology companies seeking to build fully autonomous solutions.

Developed with leading global delivery and technology companies focused on autonomous delivery and Mobility as a Service (MaaS) fleets, the Leopard concept vehicle measures 3.4 meters in length and just 1.4 meters in width. It is built on a home-brewed platform that contains the batteries, along with REEcorner units, front-wheel-steer, rear-wheel-drive, steering, suspension, motor, gearbox, and braking components.

Leopard is powered by a 50 kWh battery of unspecified range and an undisclosed type of electric motor that provides a top speed of 60 mph (96 km/h). It has a cargo capacity of 180 cubic feet (5 cubic meters) and a gross vehicle weight rating of 2 tonnes (2.2 tons). The vehicle is also designed to carry significantly more cargo due to REE’s low, flat floor.

Turbulence makes many people uneasy or downright queasy. And it’s given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that arises when a flow interacts with a boundary, but a formulation has proven elusive.

Now an international team of mathematicians, led by UC Santa Barbara professor Björn Birnir and the University of Oslo professor Luiza Angheluta, has published a complete description of boundary layer turbulence. The paper appears in Physical Review Research, and synthesizes decades of work on the topic. The theory unites empirical observations with the Navier-Stokes equation—the mathematical foundation of fluid dynamics—into a mathematical formula.

This phenomenon was first described around 1920 by Hungarian physicist Theodore von Kármán and German physicist Ludwig Prandtl, two luminaries in fluid dynamics. “They were honing in on what’s called boundary layer turbulence,” said Birnir, director of the Center for Complex and Nonlinear Science. This is turbulence caused when a flow interacts with a boundary, such as the fluid’s surface, a pipe wall, the surface of the Earth and so forth.

Are we really only a moment away from “The Singularity,” a technological event that will usher in a new era in human evolution?

A robot-assisted surgery was completed in Israel using the Da Vinci surgical system, by which the surgeon sits at a console and controls the robot.

An artificial intelligence-based method for identifying patients who are at risk for atrial fibrillation has been developed by a team led by researchers at Harvard-affiliated Massachusetts General Hospital and the Broad Institute of MIT and Harvard.

Atrial fibrillation — an irregular and often rapid heart rate — is a common condition that often leads to the formation of clots in the heart that can travel to the brain to cause a stroke. The study was published in Circulation.

The investigators developed the artificial intelligence-based method to predict the risk of atrial fibrillation within the next five years based on results from electrocardiograms (noninvasive tests that record the electrical signals of the heart) in 45,770 patients receiving primary care at MGH.

What if humanity grew to be so technologically advanced that we were able to leave our Solar System and spread across interstellar space? Would we hop from one exoplanet to another, colonizing everything on our way? How could we make traveling across the Universe possible?

Ad Astra School is the experimental school that Elon Musk started in one of SpaceX’s factories to give an education to his own children and selected children of SpaceX employees. The future of work will require a set of skills that are not taught in schools today. The future of work will involve robots and Artificial Intelligence collaborating with humans. The Astra Nova School’s pillars include caring about community, focusing on student experiences, and sharing the work they do with the world.
Here students learn about simulations, case studies, fabrication and design projects, labs, and corporate collaboration. In general, school systems are rigid. They are more system-centric than student-centric. Astra Nova is changing that by creating a philosophy of student centricity, a value for individual abilities, praising curiosity, and encouraging problem-solving and critical thinking.
