The transition in star formation rates and black hole growth as redshift decreases from regimes where positive feedback dominates to a later epoch when feedback is largely negative. CreditSteven Burrows, Rosemary Wyse, and Mitch BegelmanThe James Webb Space Telescope’s discovery of early galaxies with massive black holes challenges traditional galaxy formation theories, proposing a synchronous development of black holes and stars, a finding that could reshape our understanding of cosmic evolution.Astronomers have long…

Federal authorities have closed Canada's only known live coral reef in the Pacific Ocean to all commercial and recreational bottom-contact fishing.Fisheries and Oceans Canada says the indefinite closure came into effect on Feb. 14 for the Lophelia Reef, located in the Finlayson Channel of British Columbia's Central Coast, about 500 kilometres northwest of Vancouver and 200 kilometres directly east of Haida Gwaii.The department says the reef was first discovered in 2021 and is the "first and only" known live coral reef in…

Joe Maring / Digital Trends I’ve seen a future where you may never need apps or to unlock your phone at all, yet still get everything you want done, plus more, and even faster than you can now. At MWC 2024, Deutsche Telekom and Brain Technologies showed off the concept of an appless phone, where actions we normally perform using them are instead handled by an AI concierge that lives on the device’s lock screen. The week before the show, I spoke to Brain’s founder and CEO Jerry Yue and had an in-depth demonstration…

A groundbreaking study documents the first-ever observation of an orca individually consuming a great white shark in South Africa, challenging previous notions of orca hunting behavior and highlighting their adaptability. This discovery raises concerns about the ecological impact on shark populations and emphasizes the importance of collaborative science and adaptable conservation efforts in understanding and protecting marine ecosystems.

In a world first, researchers have printed multi-layered, living skin directly onto significant injuries in rats for scar-free skin repair. It's not sci-fi – they're genuinely 3D-printing skin (and possibly hair) right into damaged areas.The skin of the head and face is vital to protecting the structures underlying it. It’s also integral to our identity. Full-thickness skin damage caused by traumatic injury to or extensive surgery on the face or head – to remove a cancerous tumor, say – can negatively impact a person’s…

On the list of illnesses that nobody wants, cancer and HIV both rank pretty high, and Californian man Paul Edmonds had both.But ever since one particular treatment five years ago, he's been free of both cancer and HIV. The patient is now considered in remission from acute myelogenous leukemia (AML), and in another two years, he could be considered 'cured' of HIV, as that will mark five years from his last treatment.To celebrate, the medical team behind his astonishing recovery have published a letter describing the case…

Research indicates that the quality of tea is not solely dependent on the variety of tea plants but also on the microbes present on their roots. Modifying these microbial communities has been shown to significantly improve tea quality by enhancing amino acid content, suggesting a new avenue for agricultural improvement that could extend beyond tea to other crops.You’d think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. However, recent research published in the journal…

Still frame from a video generated by Sora. OpenAI's prompt was, "The camera directly faces colorful buildings in burano italy. An adorable dalmation looks through a window on a building on the ground floor. Many people are walking and cycling along the canal streets in front of the buildings." OpenAIOpen AI already has market-leading AI models in image and text generation with DALL-E 3 and ChatGPT, respectively. Now, the company is coming for the text-to-video generation space, too, with a brand-new model. Also: The…

As It Happens6:05Spider webs catch more than prey. They're also jam-packed with animal DNAJosh Newton probably isn't very popular with spiders. After all, the Australian scientist has a tendency to go around undoing their hard work. "I liken it to when Princess Fiona in Shrek makes some cotton candy for Shrek from spider webs, where she collects a stick and just wraps around the spider web for him. But I do it with a clean, sterile stick," Newton, a PhD candidate in life sciences at Curtin University, told As It Happens…

The new molecular structure in which sandwich complexes form a nano-sized ring is called ‘cyclocene.’ Credit: Nature / AOC, KITNew Compounds for Organometallic Chemistry – Sandwich Complexes in the Form of Rings Are Kept Together by Their Own EnergySandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers of Karlsruhe Institute of Technology (KIT) and the University of Marburg were the first to make…
