Three more Chinese astronauts are now stranded in space following successful rescue of their colleagues

3 more Chinese astornauts strandedThree more Chinese astronauts, or taikonauts, are now marooned in space following the successful return of their previously stranded comrades. The latest development highlights a potential flaw in China's space protocols, experts say, which could put astronauts needlessly at risk.

The latest stranded trio — Zhang Lu, Wu Fei and Zhang Hongzhang — are the crew of the Shenzhou-21 mission. They have been living onboard China's Tiangong space station since Oct. 31, shortly after they were launched into space by a Long March 2F rocket. Their mission was to take over from the station's incumbent Shenzhou-20 crew, made up of taikonauts Wang Jie, Chen Zhongrui and Chen Dong, who were originally due to return to Earth on Nov. 5.

However, after a successful handover period, the Shenzhou-20 crew's return trip was called off at the last minute when a piece of suspected space junk hit their return capsule. After tests revealed a crack in the viewing port of the struck spacecraft, the Shenzhou-20 crew boarded the return capsule designated for the Shenzhou-21 crew and successfully returned to Earth on Friday (Nov. 14).

But while many were quick to celebrate the return of the Shenzhou-20 crew, who completed the longest single spaceflight by any taikonauts (204 days), this now means that the Shenzhou-21 crew has no way of returning to Earth themselves, Live Science's sister site Space.com reported.

James Watson, co-discoverer of DNA's double helix who later courted controversy, dead at 97

James WatsonJames D. Watson, the brilliant but controversial American biologist whose 1953 discovery of the structure of DNA, the molecule of heredity, ushered in the age of genetics and provided the foundation for the biotechnology revolution of the late 20th century, has died at the age of 97.

His death was confirmed by Cold Spring Harbor Laboratory on Long Island, where he worked for many years. The New York Times reported that Watson died this week at a hospice on Long Island.

In his later years, Watson's reputation was tarnished by comments on genetics and race that led him to be ostracized by the scientific establishment.

Even as a younger man, he was known as much for his writing and for his enfant-terrible persona − including his willingness to use another scientist's data to advance his own career − as for his science.

His 1968 memoir, "The Double Helix," was a racy, take-no-prisoners account of how he and British physicist Francis Crick were first to determine the three-dimensional shape of DNA. The achievement won the duo a share of the 1962 Nobel Prize in medicine and eventually would lead to genetic engineering, gene therapy and other DNA-based medicine and technology.

Nobel Prizes in Chemistry 2025 Awarded to 3

Nobel winners in ChemistryNobel winnerChemistry winnerSusumu Kitagawa, Richard Robson and Omar M. Yaghi are awarded the Nobel Prize in Chemistry 2025 for the development of a new type of molecular architecture. The constructions they created – metal–organic frameworks – contain large cavities in which molecules can flow in and out. Researchers have used them to harvest water from desert air, extract pollutants from water, capture carbon dioxide and store hydrogen.

An attractive and very spacious studio apartment, specifically designed for your life as a water molecule – this is how an estate agent might describe one of all the metal–organic frameworks that laboratories around the world have developed in recent decades.

Other constructions of this type are tailormade for capturing carbon dioxide, separating PFAS from water, delivering pharmaceuticals in the body or managing extremely toxic gases. Some can trap the ethylene gas from fruit – so they ripen more slowly – or encapsulate enzymes that break down traces of antibiotics in the environment.

Nobel in Physics awarded to three American professors

Nobel physicsThe Nobel physics prize is awarded by the Royal Swedish Academy of Sciences and includes a prize sum totalling 11 million Swedish crowns ($1.2 million) that is shared among the winners if there are several, as is often the case.

The Nobel Prizes were established through the will of Alfred Nobel, who amassed a fortune from his invention of dynamite. Since 1901, with occaPhysics was the first category mentioned in Nobel's will, likely reflecting the prominence of the field during his time. Today, the Nobel Prize in Physics remains widely regarded as the most prestigious award in the discipline.

Past winners of the Nobel physics prize include some of the most influential figures in the history of science, such as Albert Einstein, Pierre and Marie Curie, Max Planck and Niels Bohr, himself a pioneer of quantum theory.

Webb telescope glimpses ‘volcanically growing monster’ on outskirts of Milky Way

Web image of stellar jetNASA's James Webb Telescope recently got a front-row seat to some incredible stellar fireworks on the outskirts of the Milky Way galaxy.

The eruption of gases from a stellar jet in a distant nebula is so big that NASA described it as a "volcanically growing monster star."

Need another description to put the cosmic show into context? As NASA put it, Webb's image of the stellar jet – streaking across space at hundreds of thousands of miles per hour – resembles a double-bladed dueling lightsaber like the one Darth Maul used in the "Star Wars" franchise.

Stretching across 8 light-years, the rare stellar eruption is about twice the distance between our sun and the next nearest stars, the Alpha Centauri system. The central young star, or protostar, weighing as much as 10 of our suns, is located 15,000 light-years away in the outer reaches of our galaxy.

Judge allows Trump to cut more than $1bn in National Science Foundation grants

$1B in science grants can be cutThe Trump administration can go ahead and purge more than 1,600 research grants issued by National Science Foundation (NSF) worth more than $1bn, after a judge declined to grant a preliminary injunction in a case brought by a coalition of organizations representing thousands of scientists.

The NSF is the premier federal investor in basic and cutting-edge science and engineering, which until Trump’s second term enjoyed bipartisan support, with the agency’s independent review process revered globally as the gold standard.

Shortly after the president’s inauguration, the so-called “department of government efficiency” (Doge) led by the billionaire Trump donor Elon Musk was given free rein to overhaul the NSF to comply with what the administration said were its “changing priorities”.

Doge inflicted widespread and chaotic cuts to NSF staff, programs and research grants – particularly targeting grants that complied with congressional mandates to improve participation by women, people of color and people with disabilities in science, technology, engineering and mathematics (Stem).

The congressional push to improve diversity, equity and inclusion (DEI) in science and engineering was designed to nurture and attract untapped talent in marginalized communities, in order to boost American innovation, the economy and national defense.

Dozens of scientists find errors in a new Energy Department climate report

Chris WrightA group of more than 85 scientists have issued a joint rebuttal to a recent U.S. Department of Energy report about climate change, finding it full of errors and misrepresenting climate science.

This comes weeks after the Union of Concerned Scientists and the Environmental Defense Fund filed a lawsuit against the Trump administration that alleges that Energy Secretary Chris Wright "quietly arranged for five hand-picked skeptics of the effects of climate change" to compile the government's climate report and violated the law by creating the report in secret with authors "of only one point of view."

The DOE's Climate Working Group consisted of four scientists and one economist who hahttp://tvnewslies.org/tvnl/administrator/index.php?option=com_contentve all questioned the scientific consensus that climate change is a large threat to the world and sometimes frame global warming as beneficial.

The group of climate scientists found several examples where the DOE authors cherry-picked or misrepresented climate science in the agency's report. For instance, in the DOE report the authors claim that rising carbon dioxide can be a "net benefit" to U.S. agriculture, neglecting to mention the negative impacts of more heat and climate-change fueled extreme weather events on crops.
