A super-hard metal has been made in the laboratory by melting together titanium and gold.
The alloy is the hardest known metallic substance compatible with living tissues, say US physicists.

Measuring one million times less than the width of a human hair, graphene is harder than diamonds and 200 times stronger than steel. Small, strong, and flexible, it is the most conductive material on earth and has the potential to charge a cell phone in just five seconds or to upload a terabit of data in one. It can be used to filter salt from water, develop bullet-stopping body armor, and create biomicrorobots.
These incredible properties have captured the attention of scientists and industry specialists around the world, all seeking to harness graphene’s potential for applications in electronics, energy, composites and coatings, biomedicine, and other industries.

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.

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.
