Legendary inventor Dean Kamen is working on a venture to manufacture human organs with the backing of the Pentagon, Rockwell and others.
It’s not as morbid as you think; having a reliable way of predicting people’s mortality, especially as they age, could help to improve how doctors treat disease.
Time, as far as we know, moves only in one direction. But last year, researchers found events in some gamma-ray burst pulses that seemed to repeat themselves as though they were going backwards in time.
Now, new research suggests a potential answer for what might be causing this time reversibility effect. If waves within the relativistic jets that produce gamma-ray bursts travel faster than light — at ‘superluminal’ speeds — one of the effects could be time reversibility.
Such speeding waves could actually be possible. We know that when light is travelling through a medium (such as gas or plasma), its phase velocity is slightly slower than c — the speed of light in a vacuum, and, as far as we know, the ultimate speed limit of the Universe.
At our 2019 Ending Age-related Diseases conference in New York City, we had the pleasure of speaking with Dr. Michael West, the CEO of AgeX Therapeutics.
Dr. West can rightfully be called a pioneer in his field with a substantial background in biomedical and biotechnology corporations. After completing his PhD at Baylor College of Medicine, he founded Geron Corporation in 1990, where he launched and directed programs in telomere biology as it relates to cancer, aging, and human embryonic stem cell technology. He subsequently established the research group that went on to isolate human embryonic stem cells for the first time.
Fintech risk management systems are getting a makeover. By adding machine learning technologies to their traditional rules-based fraud management systems, banks hope that they can do better at catching real criminals while declining fewer legitimate credit card transactions. ML technologies, though, have their own gotchas.
Here and there, although not necessarily everywhere, banks are introducing machine language technologies into their fraud detection systems. Essentially, the objective is twofold: to detect real incidents of fraud quickly and accurately, and to do so while preventing false positives, in which legitimate transactions are wrongly tagged as suspicious.
Large banks have led the way in spending on ML-enabled risk management, says Steven D’Alfonso, a research director at IDC responsible for compliance, fraud, and risk analytics strategies for IDC Financial Insights. Lots of bigger banks plan to expand the artificial intelligence (AI)-enabled fraud detection systems into enterprise-wide decision support systems. Many smaller banks that haven’t yet embarked on ML are expected to follow by signing on for ML managed services.

A team of researchers from the U.K., China and Spain has found that graphene exhibits mechanical properties that are similar to those of graphite. In their paper published in the journal Physical Review Letters, the group describes testing flakes of graphene in a unique way, and what they found.
Graphene is a sheet of carbon atoms just a single atom thick, sometimes called a two-dimensional material. In this new effort, the researchers questioned whether it truly is a two-dimensional material by testing it to see if it has 3D mechanical properties.
Prior research has shown that graphene does behave as a 2-D material when looking at its electronic properties. It also behaves like a 2-D material when testing its thermal properties. But until now, its mechanical properties had not been tested. The reason fis that graphene falls apart nearly instantly when not supported by a substrate, presenting difficulties in testing its mechanical properties without also including those of the substrate. To get around this problem, the researchers tested one of graphene’s mechanical properties by suspending graphene flakes in a viscous liquid, thereby preventing phonons from shaking it apart. The liquid also prevented the flakes from bonding and forming graphite. The team then carried out a common 3D test—applying high pressure, in this case, using a diamond anvil cell. Doing so showed (via Raman spectroscopy) that the energy shift that resulted from its phonons was closer to that exhibited by a 3D material (graphite) than a 2-D material.
How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets.
Instead, past U.S.-Russia arms reduction treaties have called for the destruction of the delivery systems for nuclear warheads, such as missiles and planes, but not the warheads themselves. To comply with the START treaty, for example, the U.S. cut the wings off B-52 bombers and left them in the Arizona desert, where Russia could visually confirm the airplanes’ dismemberment.
It’s a logical approach but not a perfect one. Stored nuclear warheads might not be deliverable in a war, but they could still be stolen, sold, or accidentally detonated, with disastrous consequences for human society.
According to Arpit Joshipura, The Linux Foundation’s general manager of networking, edge computing will overtake cloud computing by 2025.
The National Security Agency develops advanced hacking tools in-house for both offense and defense—which you could probably guess even if some notable examples hadn’t leaked in recent years. But on Tuesday at the RSA security conference in San Francisco, the agency demonstrated Ghidra, a refined internal tool that it has chosen to open source. And while NSA cybersecurity adviser Rob Joyce called the tool a “contribution to the nation’s cybersecurity community” in announcing it at RSA, it will no doubt be used far beyond the United States.
No one’s better at hacking than the NSA. And now one of its powerful tools is available to everyone for free.
