By using heat and temperature to modify the orientation of atoms, scientists have created a spongy, ultrastrong material that is lighter than a zip-close bag.
It seems a fusion shield could survive a supernova explosion.
“That’s what makes this white dwarf unique — it did undergo nuclear burning, but stopped before it got to iron,” Gänsicke told Space.com.
“This star is unique because it has all the key features of a white dwarf but it has this very high velocity and unusual abundances that make no sense when combined with its low mass,” Boris Gänsicke, physics professor at the University of Warwick, UK, and lead author of a paper about the research published the Monthly Notices of the Royal Astronomical Society, said in a statement.
“It would have been a type of supernova, but of a kind that that we haven’t seen before,” he added.

Multiple human organ chips that quantitatively predict drug pharmacokinetics may offer better, accelerated drug testing.
Quantifications are produced by several disciplinary houses in a myriad of different styles. The concerns about unethical use of algorithms, unintended consequences of metrics, as well as the warning about statistical and mathematical malpractices are all part of a general malaise, symptoms of our tight addiction to quantification. What problems are shared by all these instances of quantification? After reviewing existing concerns about different domains, the present perspective article illustrates the need and the urgency for an encompassing ethics of quantification. The difficulties to discipline the existing regime of numerification are addressed; obstacles and lock-ins are identified. Finally, indications for policies for different actors are suggested.
My latest blood test results are in-how’s my biological age?
In the video I discuss my dietary approach prior to my latest blood test, the blood test results, and my plan to improve them going forward.
A breakthrough COVID-19 treatment using pineapples has been accidently discovered by Australian scientists, but how does it compare to a vaccine?
Angela Cox speaks with Professor David Morris, the man behind the discovery.
“Observations of metastasising cells revealed something intriguing—a high level of something called methylmalonic acid (MMA), a metabolic byproduct that appears to accumulate as we get older.”
“So how does MMA induce these changes in cancer cells? The key seems to be in a sort of reprogramming that “switches on” a gene called SOX4.
Prior research has shown SOX4 encourages cancer cells to become more aggressive and prone to metastasis.
To test whether it was indeed SOX4 that was altering the qualities of the cancer cells, the team blocked expression of the gene, and found that MMA no longer appeared to have the same effect.
Blocking SOX4 also stopped the process by which the cancer cells were able to resist two cancer treatments.”
Research is showing a strong link between handgrip strength, walking speed, and cognition, indicating how improved physical health could boost elderly minds.
Based at Barwon Health, in the heart of Geelong’s clinical health precinct, researchers are working to identify the risk factors —such as changes in muscle mass, muscle strength and physical performance—for developing sarcopenia (loss of muscle mass, strength and function with advancing age) across the lifespan.
This testing involves the Geelong Osteoporosis Study (GOS) which began in the early 1990s, gathering adult participants from the electoral roll in the Barwon Statistical Division. During recent follow-up testing, researchers also measured cognitive function through a computer-based program, in tandem with physical health evaluations.
For decades, greater than 60% of the human genome was believed to be “junk DNA” that served little or no purpose in the course of human development. Recent research by Colorado State University is challenging this notion to show that junk DNA might be important after all.
A new study, published on June 5 in Aging Cell, found that a portion of noncoding genetic material, called repetitive element transcripts, might be an important biomarker of the aging process.
Tom LaRocca, an assistant professor in the Department of Health and Exercise Science and faculty member in the Columbine Heath Systems Center for Healthy Aging at CSU, led the study to investigate a growing body of evidence that repetitive elements—transposons and other sequences that occur in multiple copies in the human genome —may become active over time as we age.
