More accurate space-weather predictions and safer satellite navigation through radiation belts could someday result from new insights into “space waves,” researchers at Embry-Riddle Aeronautical University reported.

The group’s latest research, published on May 4, 2023, by the journal Nature Communications, shows that seasonal and daily variations in the Earth’s magnetic tilt, toward or away from the sun, can trigger changes in large-wavelength space waves.

These breaking waves, known as Kelvin-Helmholtz waves, occur at the boundary between the solar wind and the Earth’s magnetic shield. The waves happen much more frequently around the spring and fall seasons, researchers reported, while wave activity is poor around summer and winter.

I was shocked by how luxurious it was, from a bed that descends from the ceiling to built-in surround sound to lighting that can change to your mood.

It is only the optimists who achieve anything in this world —theorist John Ellis once read this adage on a candy wrapper. It stuck with him, so much so that in 1986 he referenced this candy-wrapper wisdom in his Nature article “The superstring: theory of everything, or of nothing?”

“I was pretty upbeat,” Ellis says. “I was pretty positive about it.”

According to Ellis, ‘theory of everything’ is a rather tongue-in-cheek term for an encompassing framework that links together all physical phenomena on a fundamental level. The idea went viral, both scientifically and culturally. Numerous authors, philosophers and scientific influencers jumped on the bandwagon, including the makers of a 2014 biopic about Stephen Hawking.

A fever is the immune system’s response to an infection or invader. Most fevers drop after people take over-the-counter medications. People should call a doctor if their fever reaches 103° F and go to an emergency room if it reaches 105°.

Senior execs at two blue-chip organizations explain how they’re embracing automation — and why everyone in these businesses, including IT pros, are reaping the rewards.

An Indiegogo crowdfunding campaign for the Segway Navimow robot lawn mower with VisionFence will soon launch in North America. The device can use integrated sensors to detect lawn edges and obstacles and navigate in areas of weak signal. Other features include EFLS positioning and adjustable cutting height.

It’s a dangerous world out there. From bacteria and viruses to accidents and injuries, threats surround us all the time. And nothing protects us more steadfastly than our skin. The barrier between inside and out, the body’s largest organ is also its most seamless defense.

And yet the skin is not invincible. It suffers daily the slings and arrows of outrageous fortune, and it tries to keep us safe by sensing and responding to these harms. A primary method is the detection of a pathogen, which kicks the immune system into action. But new research from the lab of Rockefeller’s Elaine Fuchs, published in Cell, reveals an alternative protective mechanism that responds to injury signals in wounded tissue—including low oxygen levels from blood vessel disruption and scab formation—and it doesn’t need an infection to get into gear.

The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens.

Google on Thursday announced a new cybersecurity training program. Those who sign up for the class will prepare for a cybersecurity analyst career and they will receive a professional certificate from Google when they graduate.

The new Cybersecurity Certificate is part of the company’s Grow With Google initiative. The program was built by Google experts and it’s hosted by online course provider Coursera.

Interested individuals can sign up for a 7-day free trial, after which they will have to pay $49 per month to continue learning.

Oh comforting solitude, how favorable thou art to original thought!
