A powerful new weather satellite launched today (March 1) from Cape Canaveral Air Force Station in Florida, heading toward a perch above the eastern Pacific Ocean to monitor extreme weather as it develops.

The satellite, called GOES-S (Geostationary Operational Environmental Satellite-S), lifted off on ULA’s Atlas V rocket at 5:02 p.m. EST (2202 GMT).

The National Oceanic and Atmospheric Administration (NOAA) will operate GOES-S in partnership with NASA. The Lockheed Martin-built satellite will join GOES-East, currently in orbit, to provide a broad, high-definition view of weather on Earth. It is the second in a series of four advanced weather satellites that will reside in geostationary orbit — hanging in place over one spot on Earth as they orbit and the world turns.

DUBAI (Reuters) — Dubai has begun testing autonomous pods in a trial run the Gulf’s trade and tourism hub hopes will help its transformation into one of the smartest cities in the world.

Officials from Dubai’s Roads and Transport Authority (RTA) displayed two cube-shaped vehicles built by U.S.-based Next Future Transportation company in Italy as they spun around on a main street in Dubai.

Passersby stopped to try out the six-seat vehicles and question the Italian engineers overseeing the test.

On February 28, 1953, American molecular biologist James D. Watson and English biophysicist Francis Crick announced to friends that they succeeded to determine the chemical structure of DNA.

Already in the 19th century biochemists were able to isolate DNA and RNA from the cell nuclei mixed together. They later found out that DNA and RNA had to be distinct from each other. The nuclein was identified by Friedrich Miescher in 1869 and he later on isolated the pure DNA from a salmon’s sperm. The term ‘nucleic acid’ was then coined by Richard Altmann and it was only found in the chromosomes. The Lithuanian-American biochemist Phoebus Levene at Rockefeller Institute made further achievements concerning the DNA’s structure, showing that its components, the sugar and phosphate chain were linked in the order phosphate-sugar-base. Each of these was named nucleotide and the scientist assumed that the DNA molecule consisted of a string of nucleotide units, which were linked together through phosphate groups.

The possibilities were almost limitless, so why does everything line up?

A potential new biomarker of aging has been discovered by researchers. This substance, found in urine, indicates oxidative damage that could be used to determine how much someone has aged biologically.

Why do we need biomarkers of ageing?

It is important for us to develop accurate and reliable biomarkers of aging, as these can show us how much we have aged biologically rather than chronologically. If we know how we are aging on a biological level, it can help to inform our healthcare strategy.

Neural networks are powerful things, but they need a lot of juice. Engineers at MIT have now developed a new chip that cuts neural nets’ power consumption by up to 95 percent, potentially allowing them to run on battery-powered mobile devices.

Smartphones these days are getting truly smart, with ever more AI-powered services like digital assistants and real-time translation. But typically the neural nets crunching the data for these services are in the cloud, with data from smartphones ferried back and forth.

That’s not ideal, as it requires a lot of communication bandwidth and means potentially sensitive data is being transmitted and stored on servers outside the user’s control. But the huge amounts of energy needed to power the GPUs neural networks run on make it impractical to implement them in devices that run on limited battery power.
