What could we do to stop our Sun from eventually expanding and burning out? In this Cosmic Query, astrophysicist Neil deGrasse Tyson explains how we can prolong the life of a star. Co-host Chuck Nice offers his sci-fi option for Earth’s future.

A new Council on Foreign Relations Report concludes that the U.S. better put in place a national innovation strategy if it is to keep its world-leading position against its number one challenger, China.

He has produced over 500 segments for the network. His investigative reports on security policy, espionage activities and weapons technology appear in leading newspapers, television networks and magazines throughout Europe, including Cicero, Focus, PC-Welt, Playboy, Stern, Welt am Sonntag and ZEITmagazin. He is author of a widely acclaimed book on electronic intelligence activities, “High-Tech Espionage” (St. Martin’s Press), published in fourteen countries. He is Executive Producer for a weekly technology magazine on international television in the Arab world. For his latest book “Evolution without us – Will AI kill us?” he researched at US drone bases, the Pentagon, intelligence agencies and AI research institutions. His lively talks are accompanied by exclusive video and photographs.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

You have to admit it. Some of the uses of artificial intelligence are simply fascinating. One of the more exciting aspects of artificial intelligence is seeing all the potential ways the technology can be applied to our daily lives, even if it at times it seems a little creepy. We have seen artificial intelligence technology shape everything from the medical world to art. However, did you ever think that AI would go on to shape the world of stock images?

Supernova explosions can crush ordinary stars into neutron stars, composed of exotic, extremely dense matter. Neutron stars are on the order of about 12 miles (20 km) across in contrast to hundreds of thousands of miles across for stars like our sun. Yet they contain mass on the order of 1.4 times that of our sun. Neutron stars have strong magnetic fields. They emit powerful blasts of radiation along their magnetic field lines. If, as a neutron star spins, its beams of radiation periodically point towards Earth, we see the star as a pulsing radio or gamma-ray source. Then the neutron star is also called a pulsar, often compared to a cosmic lighthouse. Modern astronomers know of pulsars spinning with mind-boggling rapidity. The second-fastest one – called PSR J0952-0607 – spins some 707 times a second! Scientists at the Max Planck Institute for Gravitational Physics in Hanover, Germany announced on September 19, 2019, that this pulsar, J0952-0607 – formerly seen only at the radio end of the spectrum – now has been found to pulse also in gamma rays.

J0952-0607 – the number relates to the object’s position in the sky – was first discovered in 2017. It was originally seen to pulse in radio waves, but not gamma rays. The international team that studied it in detail – and recently published new work about it in the peer-reviewed Astrophysical Journal – said in a statement:

The pulsar rotates 707 times in a single second and is therefore the fastest spinning in our galaxy outside the dense stellar environments of globular clusters.

Food security is one of the biggest challenges we’re facing as we move further into this century. Changing climate, pests, stress on water and land are all limiting our ability to produce sufficient amounts of food. making food production an issue.

Synthetic biology offers ways to help produce and supply enough safe and nutritious food sustainably for the estimated 9 billion people that will inhabit the planet by 2050.

Here are a few ways how.

We think of an attack as a ‘big bang’, but the symptoms can build over hours or days – and even doctors can misinterpret them.

Solar power is on the rise. You can see the evidence on rooftops and in the desert, where utility-scale solar plants are popping up. The picture is not all rosy, but if the recent past is any indication, solar power is going to help lead the transition to a carbon-free future, and it might do it faster than we all expected.

Elon Musk and Tesla promised solar roof tiles in 2016, but the industry might not need an upgrade as its grown significantly with the solar panels currently available. You can see the evidence both on individual rooftops and in the utility-scale solar plants increasingly popping up in deserts across the country. In the United States, of all about 30% of the new power capacity added to the grid in 2018 was from solar.

(Bloomberg) — For years, wind and solar power were derided as boondoggles. They were too expensive, the argument went, to build without government handouts.

Today, renewable energy is so cheap that the handouts they once needed are disappearing.

On sun-drenched fields across Spain and Italy, developers are building solar farms without subsidies or tax-breaks, betting they can profit without them. In China, the government plans to stop financially supporting new wind farms. And in the U.S., developers are signing shorter sales contracts, opting to depend on competitive markets for revenue once the agreements expire.
