“Although this research field has been very active for more than 20 years, this is the first field-result that experimentally demonstrates lightning guided by lasers,” the researchers wrote in the study. “This work paves the way for new atmospheric applications of ultrashort lasers and represents an important step forward in the development of a laser based lightning protection for airports, launchpads or large infrastructures.”
Lightning emerges when atmospheric static electricity, generated by the friction of ice clumps and rain in stormclouds, separates electrons from atoms. The negatively charged electrons then pool at the stormcloud’s base and attract positive charges from the ground. As electrons steadily accumulate, they begin to overcome the resistance of the air to their flow, ionizing the atmosphere below them as they approach the ground in multiple forking (and invisible) “leader” paths. When the first leader path makes contact with the ground, electrons hop to the earth from the point of contact, discharging from the bottom up in a flash of lightning (called the return stroke) that travels to the top of the cloud.
Crews caught in sun-free cycles will need to get creative with energy production.
When astronauts on the Artemis mission and beyond spend long periods in Lunar Night, they’ll need innovative forms of energy to power vehicles and research instruments.
When the bird on the left died off 65 million years ago, why did the one on the right thrive?
Janavis, a beak-toothed bird died while another species called the Wonderchicken survived. Could being smaller explain why the latter lived?
But experts warn that such sites could spew out hateful content.
We all have heard of ChatGPT by now but there are some other incredible applications out there that let you indulge in perhaps even more engaging conversations. The Hello History app and Character. AI websites allow users to speak with both fictional and historical figures such as Tony Stark or Shakespeare.
How can AI chatbots connect us with philosophers?

This “may be the first direct detection of a ‘Gaia exoplanet.’”
The European Space Agency’s (ESA’s) Gaia spacecraft helped capture an exoplanet, paving the way for follow-up observations that revealed the distant planet had a nuclear fusion reaction in its core.
“The discovery of HD 206,893 c is a really important moment for the study of exoplanets, as ours may be the first direct detection of a ‘Gaia exoplanet,’” Professor Sasha Hinkley at the University of Exeter in England explained in a press statement.

Amazon has launched an “educator enablement” program to help instructors at community colleges, HBCUs, and other minority-serving institutions learn and teach AI.
Quality AI education is still out of reach for many students who don’t attend selective research universities including many Black and Latino/a students. Amazon hopes to change that by investing in AI education at community colleges and HBCUs.
To ban, or not to ban, that is the question. I would guess that if Shakespeare were around nowadays, he might have said something like that about the recent efforts to ban the use of a type of AI known as Generative AI
Here’s the deal.
Some rather high-profile bans have been announced regarding the use of generative AI such as ChatGPT. We need to closely examine these bans and decide whether they make any sense. Here’s the scoop.
Alphabet, parent holding company of Google, has announced that it’s cutting around 6% of its global workforce.
In an open letter published by Google and Alphabet CEO Sundar Pichai, the narrative followed a similar trajectory to that of other companies that have downsized in recent months, noting that the company had “hired for a different economic reality” than what it’s up against today.
Put simply, it had bolstered its workforce during the pandemic-driven digital boom times, but it’s now having to reverse course as the world curtails its spending in the face of economic headwinds.
Google CEO Sundar Pichai announced the news in an email to staff, saying the company needed to focus on key priorities — like artificial intelligence.
Google is cutting approximately 12,000 jobs — the latest technology firm to initiate significant layoffs as inflation rises and global markets brace for a downturn.
Google SEO Sundar Pichai announced the cuts in an email to staff on Friday and a blog post. The job losses constitute around 6 percent of Google’s global workforce, compared to recent layoffs at Microsoft (10,000 jobs or 5 percent of the workforce), Amazon (18,000 jobs / 6 percent), and Meta (11,000 / 13 percent).
