In the far reaches of the Universe, astronomers have managed to capture a rare interaction. As a supermassive black hole ravenously slurps down matter around it, it’s sending out jets of plasma — pushing into and heating the gas in the galaxy around it.

This is difficult to capture at the best of times, but this case was a particularly impressive feat. The galaxy in question is a whopping 11 billion light-years away — when the Universe was less than 3 billion years old.

It’s called MG J0414+0534, and astronomers managed to capture it in detail because of gravitational lensing. In between us and the galaxy is a different, rather massive galaxy whose gravity distorts the path of the light travelling from behind it, creating four images of MG J0414+0534 around it (see image below).

NASA’s new spacesuit may not look any different from the one used for spacewalks outside the International Space Station recently, but the US space agency says the suit is designed to achieve more complex tasks than its predecessors. The new suit, which will be worn by astronauts on the Artemis lunar exploration program, is called the Exploration Extravehicular Mobility Unit, or xEMU for short.

While the spacesuit is still under development, its features have been finalised. It’s already being tested underwater, and orbital testing is scheduled for 2023. Take a look:

1. Can extreme withstand temperatures of −250 degrees Fahrenheit in shade and up to 250 degrees Fahrenheit in the sun.

The obvious drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, which has a frigid temperature, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work, in a recent issue of Applied Physics Letters, from AIP Publishing, looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019–2029.

An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe. The infrared semiconductor device faces the sky and uses the temperature difference between Earth and space to produce the electricity.

“The vastness of the universe is a thermodynamic resource,” said Shanhui Fan, an author on the paper. “In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation.”

Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as “T-rays,” are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone. However, to date, waves are wasted energy, as there has been no practical way to capture and convert them into any usable form.

Now physicists at MIT have come up with a blueprint for a they believe would be able to convert ambient terahertz waves into a , a form of electricity that powers many household electronics.

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.

A 15-member research team from the U.K., Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of 2.1 micrometers. In practice, entangled photons are used in encryption methods such as quantum key distribution to completely secure telecommunications between two partners against eavesdropping attempts. The research results are presented to the public for the first time in the current issue of Science Advances.

It has been regarded as technically possible to implement encryption mechanisms with entangled photons in the near-infrared range of 700 to 1550 nanometers. However, these have disadvantages, especially in satellite-based communication. They are disturbed by light-absorbing gases in the atmosphere as well as the background radiation of the sun. With existing technology, end-to-end encryption of transmitted data can only be guaranteed at night, but not on sunny and cloudy days.

Many people are turning to Zoom in this time. I suggested my Dad use it for his church…but…Watch Out! After #coronavirus domains, experts find a massive surge in suspicious “Zoom” named domains in the last 7 days, potentially registered by hackers to exploit #Zoom’s overnight success in this pandemic time to spread #malware… #COVID19

Covid-19 impact: hackers begin exploiting zoom’s overnight success to spread malware during coronavirus outbreak with fake domains and websites.

Circa 2018: In January 2017, while one of us was serving as a homeland security advisor to outgoing President Barack Obama, a deadly pandemic was among the scenarios that the outgoing and incoming U.S. Cabinet officials discussed in a daylong exercise that focused on honing interagency coordination and rapid federal response to potential crises. The exercise is an important element of the preparations during transitions between administrations, and it seemed things were off to a good start with a commitment to continuity and a focus on biodefense, preparedness, and the Global Health Security Agenda—an initiative begun by the Obama administration to help build health security capacity in the most critically at-risk countries around the world and to prevent the spread of infectious disease. But that commitment was short-lived.

Deadly diseases like Ebola and the avian flu are only one flight away. The U.S. government must start taking preparedness seriously.
