The brain is assumed to be hypoactive during cardiac arrest. However, animal models of cardiac and respiratory arrest demonstrate a surge of gamma oscillations and functional connectivity. To investigate whether these preclinical findings translate to humans, we analyzed electroencephalogram and electrocardiogram signals in four comatose dying patients before and after the withdrawal of ventilatory support. Two of the four patients exhibited a rapid and marked surge of gamma power, surge of cross-frequency coupling of gamma waves with slower oscillations, and increased interhemispheric functional and directed connectivity in gamma bands. High-frequency oscillations paralleled the activation of beta/gamma cross-frequency coupling within the somatosensory cortices. Importantly, both patients displayed surges of functional and directed connectivity at multiple frequency bands within the posterior cortical “hot zone,” a region postulated to be critical for conscious processing. This gamma activity was stimulated by global hypoxia and surged further as cardiac conditions deteriorated in the dying patients. These data demonstrate that the surge of gamma power and connectivity observed in animal models of cardiac arrest can be observed in select patients during the process of dying.

At Wednesday’s Google I/O conference, Google announced wide availability of its ChatGPT-like AI assistant, Bard, in over 180 countries with no waitlist. It also announced updates such as support for Japanese and Korean, visual responses to queries, integration with Google services, and add-ons that will extend Bard’s capabilities.

Google plans to add Google Lens integration to Bard, which will allow users to include photos and images in their prompts. On the Bard demo page, Google shows an example of uploading a photo of dogs and asking Bard to “write a funny caption about these two.” Reportedly, Bard will analyze the photo, detect the dog breeds, and draft some amusing captions on demand.

The findings suggest the star Fomalhaut may have orbiting planets hidden among its rings of debris.

Some GPU cryptomining outfits, having survived a bleak winter of discontent, have started to grasp AI acceleration opportunities.

An international team of astronomers including several Dutch researchers has observed, for the first time, the benzene molecule (C₆H₆) in a planet-forming disk around a young star. Besides benzene, they saw many other, smaller carbon compounds and few oxygen-rich molecules. The observations suggest that, like our own Earth, the rocky planets forming in this disk contain relatively little carbon. The scientists published their findings in the journal Nature Astronomy.

The researchers studied the young, small star J160532 (one tenth of the mass of our sun) some 500 light years away from us towards the constellation Scorpio. Around such small young stars, many rocky planets similar to Earth form, in disks made of gas and dust. Until now, it has been difficult to study molecules in the warm inner part of these disks where the majority of planets form due to the limited sensitivity and spectral resolution of previous observatories.

For their research, the scientists used data from the MIRI spectrometer aboard the James Webb Space Telescope. MIRI can see right through dust clouds and is particularly well suited to measure hot gas in inner disks. The main optics of the MIRI spectrometer were designed and built by the Netherlands Research School for Astronomy (NOVA).

Researchers at Tufts University developed immortalized bovine muscle stem cells for cellular agriculture, potentially overcoming scaling challenges for meat production.

Andrew Stout, Tufts University.

Currently, it is difficult and expensive to produce cell-cultured meat because muscle and fat cells need to be able to grow and divide rapidly. Normal muscle stem cells can only divide about 50 times before they stop dividing and die. However, immortalized cells developed by the TUCCA team can divide indefinitely, which means they can produce much more meat.

That may just be all that the company has to offer right now.

Google’s I/O event which is currently underway is the platform for the company to showcase how it plans to take on the might of Microsoft in the next frontier of technology, artificial intelligence (AI). What the company’s loyal followers seem to have gotten is a rebranding of its AI tools for Docs and Gmail, The Verge.

The company offers features such as a large window dome with a view of space, internet access via onboard Wi-Fi, and a dedicated room for exercise and rest at Haven-1.

We have entered a brand new era of space exploration, from flying a chopper on Mars to re-directing an asteroid’s trajectory to retrieving soil samples from a distant space rock.

The future of space is dynamic, with technological prowess allowing science fiction-inspired ideas to become reality. And next-generation space outposts are one such area that has piqued the interest of space startups. Especially since the International Space Station (ISS) is scheduled to be decommissioned by the end of this decade.

China is developing the fully reusable Long March 9 rocket, which will have a similar design to Starship.

A team of rocket scientists in China reportedly provided an accurate diagnosis of the problem that caused Starship to spiral out of control before Elon Musk’s SpaceX released its own official statement on the massive Mars rocket, a report from the.

The fully-integrated Starship launch system spun out of control shortly after it first took to the skies, on April 20, in what was an otherwise successful first flight test.
