Tumor matrix profiling gives clues to progression of some lung cancers

Posted by in category: biotech/medical

Scientists at the Garvan Institute of Medical Research have identified molecular profiles of the surrounding matrix of a common type of lung cancer that might indicate which patients are likely to develop aggressive tumors.

Squamous cell carcinoma is the second most prevalent type of . Yet treatment options for these patients remain limited and have remained largely unchanged over decades. High rates of recurrence and chemotherapy resistance mean that less than one in five patients will survive more than five years after their diagnosis.

In addition to studying , Garvan researchers have been turning their attention to the environment that surrounds these cancer cells in the tumor. A major component of this environment is the , a 3D meshwork of around 300 core molecules. This matrix is present in all tissues in the body, where it normally provides structural and functional support to hold cells together. But in cancers, this matrix is fundamentally altered and these changes can promote .

Why This Universe? New Calculation Suggests Our Cosmos Is Typical

Posted by in categories: mathematics, quantum physics

“It’s a novel contribution that uses different methods compared to what most people have been doing,” said Steffen Gielen, a cosmologist at the University of Sheffield in the United Kingdom.

The provocative conclusion rests on a mathematical trick involving switching to a clock that ticks with imaginary numbers. Using the imaginary clock, as Hawking did in the ’70s, Turok and Boyle could calculate a quantity, known as entropy, that appears to correspond to our universe. But the imaginary time trick is a roundabout way of calculating entropy, and without a more rigorous method, the meaning of the quantity remains hotly debated. While physicists puzzle over the correct interpretation of the entropy calculation, many view it as a new guidepost on the road to the fundamental, quantum nature of space and time.

Diabetes Drug Linked to a Decreased Risk of Dementia

Posted by in categories: biotech/medical, neuroscience

According to the researchers, these drugs may effectively prevent dementia in high-risk individuals with mild to moderate type 2 diabetes, and it may now be worthwhile to give them priority in future clinical trials to determine whether they can be repurposed.

Researchers have begun to investigate whether diabetes drugs could potentially help prevent or cure dementia since type 2 diabetes and dementia share several physiological patterns. However, the results have been inconsistent thus far.

The researchers compared the incidence of dementia in older adults with type 2 diabetes who were receiving either sulfonylurea or thiazolidinedione (TZD) with those receiving metformin alone in order to shed further light on this.

Researchers simulated a black hole on Earth, and it actually started to glow

Posted by in category: cosmology

A group of researchers recently simulated the event horizon of a man-made black hole in a lab. The new analog could help us learn more about the elusive radiation that is believed to be emitted by real black holes out in space. Black holes are by far one of the most mysterious objects in space.

Humans to live on the moon

Posted by in category: space travel

The Artemis mission is preparing astronauts for this lofty goal.

Humans are on course to be living and even working on the moon by 2030, a NASA official told BBC’s Sunday.


Howard Hu, the head of the U.S. agency’s Orion lunar spacecraft programme, said astronauts could stay on the celestial object for extended periods of time by the end of this decade.

Even a small nuclear war could cause global famine — here’s what the data shows

Posted by in categories: climatology, computing, existential risks, geopolitics, military, nuclear weapons, treaties

Nuclear arsenals remain large enough to fundamentally shift the Earth system in the blink of an eye.

The U.S. and Russia have recently agreed to hold talks on the New START Treaty, and the only accord left regulating the two largest nuclear arsenals in the world. While this is undoubtedly good news, we must not allow it to lull us into complacency. Global events this year, most notably in Ukraine, have raised fears of a nuclear conflict to levels not seen since the cold war. More than 10,000 nuclear warheads remain in the world, and the Kremlin’s language regarding weapons of mass destruction has become increasingly threatening in 2022.

Twitter could ‘face outage’ during FIFA World Cup 2022, claims insider

Posted by in category: futurism

‘First World Cup match on Sunday! Watch on Twitter for best coverage & real-time commentary,’ Musk tweeted earlier.

Twitter has a 50–50 chance of experiencing a major crash during the FIFA World Cup 2022, a recently departed employee, told The Guardian.

The former employee has intimate knowledge of the workings of the Twitter Command Centre, the platform’s center for troubleshooting issues that arise during high traffic to the site. “Between the lack of preparations and the lack of staffing, I think it’s going to be a rough World Cup for Twitter,” he said.

Elon Musk ends Trump’s Twitter ban

Posted by in category: Elon Musk

Former President Donald Trump’s Twitter account has been reinstated following a permanent ban in January 2021.

On Friday, new Twitter owner Elon Musk posted a poll asking if Trump should be allowed back on the platform. Just over 15 million people voted, with 51.8% voting in favor of reinstating Trump on Twitter.

As of July 2022, when Twitter filed its last quarterly earnings report before going private, the platform has about 237.8 million monetizable daily active users. Yet when Musk’s impromptu poll ended on Saturday with a small fraction of the user base taking part, Trump’s account was unbanned.
