(Harvard-Smithsonian Center for Astrophysics) – Astrophysicists have performed a new analysis that places the most precise limits yet on the composition and evolution of the universe. With this analysis, dubbed Pantheon+, cosmologists find themselves at a crossroads.
Pantheon+ finds that the cosmos is composed of about two-thirds dark energy and one-third matter – mostly in the form of dark matter – and is expanding at an accelerating pace over the last several billion years. However, Pantheon+...
Ye, formerly known as Kanye West, has agreed to buy the self-styled "uncancellable" social-media platform Parler, the company has announced.
Last week, the star's Twitter and Instagram accounts were locked, after he posted anti-Semitic messages, the BBC reports.
Ye "will never have to fear being removed from social media again," chief executive George Farmer posted.
The announcement on PR Newswire reveals little about the terms of the deal.
It says: "Under the terms of their agreement in principle, the parties intend...
Teen overdose deaths have never been higher in the U.S. as young people are increasingly poisoned by the synthetic opiate fentanyl, even as fewer teens use drugs.
More than 100,000 Americans died of drug overdoses last year — the vast majority were adults — but the fastest growing group to die of overdoses was teenagers, the BBC reports.
Fentanyl is typically smuggled into the United States by Mexican drug cartels. While it used to be laced...
NASA on Tuesday celebrated exceeding expectations during a mission to deflect a distant asteroid, in a sci-fi-like test of humanity's ability to stop an incoming cosmic object from devastating life on Earth.
The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on Sept. 26, pushing it into a smaller, faster orbit around its big brother Didymos, NASA chief Bill Nelson said.
That changed its orbital period by 4%, or 32...
A Chinese firm tested out an electric flying taxi in Dubai on Monday, offering a glimpse of futuristic technology that could one day whisk people through cities high above any land traffic.
The XPeng X2, developed by the Guangzhou-based XPeng Inc's aviation affiliate, is one of dozens of flying-car projects around the world. Only a handful have been successfully tested with passengers on board, and it will likely be many years before any are put...
Using an off-the-shelf automotive radar sensor and a novel processing approach, Pennsylvania State University researchers demonstrated they could detect the vibrations of a cell phone's earpiece and decipher what the person on the other side of the call was saying with up to 83% accuracy.
The demonstration, available in the 2022 IEEE Symposium on Security and Privacy (SP), reveals a significant security concern, according to Mahanth Gowda, assistant professor of computer science and engineering, and doctoral...
A "poisoner was at work" at a hospital where there was a "significant rise" in the number of healthy babies dying, a court has heard.
Lucy Letby has been accused of murdering five baby boys and two girls, and attempting to murder 10 other babies at Countess of Chester hospital, the BBC reports.
Nick Johnson KC, prosecuting, said she was a "constant malevolent presence" in the hospital's neonatal unit.
Letby, 32, of Hereford, denies 22 charges at...
University of Maryland School of Medicine researchers have identified how multiple genes of SARS-CoV-2 affect disease severity, which could lead to new ways in how we develop future vaccines or develop newer treatments. The genes control the immune system of the host, contributing to how fiercely the body responds to a COVID-19 infection, writes Vanessa McMains of the UMSOM.
Although people typically think of the spike protein that forms the structural "crown" as the driving...
Amid much speculation and research about how our genetics affect the way we age, a University of California, Berkeley, study shows that individual differences in our DNA matter less as we get older and become prone to diseases of aging, such as diabetes and cancer.
In a study of the relative effects of genetics, aging, and the environment on how some 20,000 human genes are expressed, the researchers found that aging and environment are far more important...
Iran's state-run broadcaster was apparently hacked on air Saturday, with a news bulletin interrupted by a protest against the country's leader.
A mask appeared on the screen, followed by an image of Supreme Leader Ali Khamenei with flames around him, the BBC reports.
The group called itself "Adalat Ali", or Ali's Justice.
It comes after at least three people were shot dead when protesters clashed with security forces in new unrest over the death of Mahsa Amini.
Amini...
