Australian researchers say enzyme could help lower lower CO2

All, News
SYDNEY — Australian scientists say they have discovered how an enzyme “hidden in nature’s blueprint” could help develop climate-resilient crops able to remove more carbon dioxide from the atmosphere.  An Australian study, by researchers from Australian National University and the University of Newcastle in New South Wales, focuses on a type of bacteria researchers call “tiny carbon superheroes.”  Cyanobacteria, a type of algae-like bacteria also called blue-green algae, are found in fresh and coastal waters, as well as oceans.  They are commonly known for their toxic blooms in lakes and rivers.   Through the process of photosynthesis, Australian scientists say, they capture about 12% of the world’s carbon dioxide each year.  Their study says a carbon dioxide-concentrating mechanism in cyanobacteria lets them turn atmospheric carbon dioxide into sugars for cells to eat…

Scholar called ‘Putin’s brain’ attacked on Chinese internet

All, Business, News, Technology
Washington — Aleksander Dugin, a Russian nationalist ideologue and strong supporter of President Vladimir Putin, has been bombarded with attacks on Chinese social media, where netizens criticized and mocked his Russian expansionist views that had once included the dismembering of China. Two years after Putin launched an invasion of Ukraine, pro-Russia sentiment has been prevalent on Chinese internet. But the backlash against Dugin has revealed a less mentioned side of what has so far appeared to be a cozy alliance between Beijing and Moscow -- hostility between Chinese nationalists and their Russian counterparts, the result of centuries of territorial disputes and political confrontations that Beijing has been reticent about displaying publicly in recent decades. On May 6, Dugin opened an account on two of the most popular Chinese social media apps…

US arrests American and Ukrainian in North Korea-linked IT infiltration scheme

All, Business, News, Technology
WASHINGTON — U.S. prosecutors on Thursday announced the arrests of an American woman and a Ukrainian man they say helped North Korea-linked IT workers posing as Americans to obtain remote-work jobs at hundreds of U.S. companies. The U.S. Department of Justice (DoJ) said the elaborate scheme, aimed at generating revenue for North Korea in contravention of international sanctions, involved the infiltration of more than 300 U.S. firms, including Fortune 500 companies and banks, and the theft of the identities of more than 60 Americans. A DoJ statement said the overseas IT workers also attempted to gain employment and access to information at two U.S. government agencies, although these efforts were "generally unsuccessful." An earlier State Department statement said the scheme had generated at least $6.8 million for North Korea. It said…

Webb telescope uncovers merger of two massive black holes from early universe

All, News
CAPE CANAVERAL, FLORIDA — The Webb Space Telescope has discovered the earliest known merger of black holes. These two gigantic black holes and their galaxies consolidated just 740 million years after the universe-forming Big Bang. It's the most distant detection ever made of merging black holes, scientists reported Thursday. One black hole is 50 million times more massive than our sun. The other is thought to be similar in size, but is buried in dense gas, which makes it harder to measure. Until now, astronomers weren't sure how supermassive black holes got so big. The latest findings, published in the Monthly Notices of the Royal Astronomical Society, suggest mergers are how black holes can grow so rapidly — "even at cosmic dawn," said lead author Hannah Ubler of the University of…

Fewer US overdose deaths reported last year, but experts still cautious

All, News
NEW YORK — The number of fatal overdoses in the U.S. fell last year, according to Centers for Disease Control and Prevention data posted Wednesday. Agency officials noted that the data is provisional and could change after more analysis, and that they still expect a drop when the final counts are in. It would be only the second annual decline since the current national drug death epidemic began more than three decades ago. Experts reacted cautiously. One described the decline as relatively small and said it should be thought of as part of a leveling off rather than a decrease. Another noted that the last time a decline occurred — in 2018 — drug deaths shot up in the years that followed. "Any decline is encouraging," said Brandon Marshall, a Brown…

New Zealand researchers say artificial intelligence could enhance surgery

All, Business, News, Technology
SYDNEY — Researchers in New Zealand say that artificial intelligence, or AI, can help solve problems for patients and doctors.   A new study from the University of Auckland says that an emerging area is the use of AI during operations using so-called "computer vision." The study, published in the journal Nature Medicine, says that artificial intelligence has the potential to identify abnormalities during operations and to unburden overloaded hospitals by enhancing the monitoring of patients to help them recover after surgery at home. The New Zealand research details how AI “tools are rapidly maturing for medical applications.”  It asserts that “medicine is entering an exciting phase of digital innovation.” The New Zealand team is investigating computer vision, which describes a machine’s understanding of videos and images.    Dr. Chris Varghese,…

Biden sharply hikes US tariffs on billions in Chinese chips, cars

All, Business, News, Technology
WASHINGTON — U.S. President Joe Biden on Tuesday unveiled a bundle of steep tariff increases on an array of Chinese imports including electric vehicles, computer chips and medical products, risking an election-year standoff with Beijing in a bid to woo voters who give his economic policies low marks. Biden will keep tariffs put in place by his Republican predecessor Donald Trump while ratcheting up others, including a quadrupling of EV duties to over 100%, the White House said in a statement. It cited "unacceptable risks" to U.S. economic security posed by what it considers unfair Chinese practices that are flooding global markets with cheap goods. The new measures impact $18 billion in Chinese imported goods including steel and aluminum, semiconductors, batteries, critical minerals, solar cells and cranes, the White House said.…

Dazzling auroras fade from skies as sunspot turns away

All, News
Washington — The spectacular auroras that danced across the sky in many parts of the world over the weekend are fading, scientists said Monday, as the massive sunspot that caused them turns its ferocious gaze away from Earth. Since Friday, the most powerful solar storm to strike our planet in more than two decades has lit up night skies with dazzling auroras in the United States, Tasmania, the Bahamas and other places far from the extreme latitudes where they are normally seen. But Eric Lagadec, an astrophysicist at France's Observatoire de la Cote d'Azur, told AFP that the "most spectacular" period of this rare event has come to an end. The first of several coronal mass ejections (CMEs) -- expulsions of plasma and magnetic fields from the Sun -- came just…

US vows to stay ahead of China, using AI for fighter jets, navigation

All, Business, News, Technology
Washington — Two Air Force fighter jets recently squared off in a dogfight in California. One was flown by a pilot. The other wasn’t. That second jet was piloted by artificial intelligence, with the Air Force’s highest-ranking civilian riding along in the front seat. It was the ultimate display of how far the Air Force has come in developing a technology with its roots in the 1950s. But it’s only a hint of the technology yet to come. The United States is competing to stay ahead of China on AI and its use in weapon systems. The focus on AI has generated public concern that future wars will be fought by machines that select and strike targets without direct human intervention. Officials say this will never happen, at least not on…

First patient to get gene-edited pig kidney transplant dies 

All, News
Washington — The first living patient to receive a genetically modified pig kidney transplant has died two months after the procedure, the US hospital that carried it out said. "Mass General is deeply saddened at the sudden passing of Mr. Rick Slayman. We have no indication that it was the result of his recent transplant," the Boston hospital said in a statement issued late Saturday. In a world first, surgeons at Massachusetts General Hospital in March successfully transplanted the genetically edited pig kidney into Slayman, who was 62 years old at the time and suffering from end-stage kidney disease. "Slayman will forever be seen as a beacon of hope to countless transplant patients worldwide and we are deeply grateful for his trust and willingness to advance the field of xenotransplantation," the…

Technology crushing human creativity? Apple’s new iPad ad has strikes nerve online

All, Business, News, Technology
NEW YORK — A newly released ad promoting Apple's new iPad Pro has struck quite a nerve online. The ad, which was released by the tech giant Tuesday, shows a hydraulic press crushing just about every creative instrument artists and consumers have used over the years — from a piano and record player, to piles of paint, books, cameras and relics of arcade games. Resulting from the destruction? A pristine new iPad Pro. "The most powerful iPad ever is also the thinnest," a narrator says at the end of the commercial. Apple's intention seems straightforward: Look at all the things this new product can do. But critics have called it tone-deaf — with several marketing experts noting the campaign's execution didn't land. "I had a really disturbing reaction to the ad,"…

Dogs entering US must be 6 months old, microchipped to prevent rabies spread

All, News
New York — All dogs coming into the U.S. from other countries must be at least 6 months old and microchipped to help prevent the spread of rabies, according to new government rules published Wednesday. The new rules require vaccination for dogs that have been in countries where rabies is common. The update applies to dogs brought in by breeders or rescue groups as well as pets traveling with their U.S. owners. "This new regulation is going to address the current challenges that we're facing," said Emily Pieracci, a rabies expert at the Centers for Disease Control and Prevention who was involved in drafting the updated regulations. The CDC posted the new rules in the federal register on Wednesday. They take effect Aug. 1 when a temporary 2021 order expires. That…

It’s not a matter of if a hurricane will hit Florida, but when, forecasters say

All, News
SANFORD, Florida — With the start of hurricane season less than a month away, U.S. officials who predict, prepare for and respond to natural disasters had a message for Floridians on Friday: It's not a matter of if a hurricane will hit, but when. The 2024 hurricane season is expected to be busier than average. To ensure that people everywhere are prepared, officials visited residents in Sanford, a landlocked city in the middle of the Sunshine State.
