The stylish and stealthy microphone may be useful for monitoring patient health or as aids to its hearing impaired wearers.
Artificial intelligence is the buzziest of buzz words on Wall Street. Apart, that is, for the two firms that are seen to be at the cutting edge of the technology.
Dr Jordan B Peterson and Dr. Del Paulhus delve deep into the Dark Tetrad: Machiavellianism, Narcissism, Psychopathy, and the newly added Sadism. From these four traits, researchers can quantify much of the darkness of humanity, and begin to study it in a way that yields numerical results, and the potential to make substantial predictions.
Dr. Delroy Paulhus is a personality researcher whose work in dark personality traits, via a variety of psychometric methods, has yielded measures of the Dark Tetrad. His work has also validated measures of socially desirable responding, perceived control, free will and determinism, and over-claiming. His work has been published in over 150 articles and books, and his current citation count exceeds 43,000.

At least, that was the assumption in the second half of the 19th century. This scenario became known as the “heat death” of the universe, and it seemed to be the nail in the coffin for any optimistic cosmology that promised, or even allowed, eternal life and consciousness. For example, one of the most popular cosmological models of the time was put forth by the evolutionary theorist Herbert Spencer, a contemporary of Charles Darwin who was actually more famous than him during their time. Spencer believed that the flow of energy through the universe was organizing it. He argued that biological evolution was just part of a larger process of cosmic evolution, and that life and human civilization were the current products of a process of continual cosmic complexification, which would ultimately lead to a state of maximal complexity, integration and balance among all things.
When the prominent Irish physicist John Tyndall told Spencer about the heat death hypothesis in a letter in 1858,” Spencer wrote him back to say it left him “staggered”: “Indeed, not seeing my way out of the conclusion, I remember being out of spirits for some days afterwards. I still feel unsettled about the matter.”
Things got even gloomier when the Austrian physicist Ludwig Boltzmann put forward a new statistical interpretation of the second law in the latter half of the 19th century. That was when the idea that the universe is growing more disordered came into the picture. Boltzmann took the classical version of the second law — that useful energy inevitably dissipates — and tried to give it a statistical explanation on the level of molecules colliding and spreading out. He used one of the simplest models possible: a gas confined to a box.
Transcatheter mitral valve repair for heart failure patients with mitral regurgitation can reduce the long-term rate of hospitalizations by almost 50 percent, and death by nearly 30 percent, compared with heart failure patients who don’t undergo the minimally invasive procedure.
These are the breakthrough findings from a new study led by a researcher from the Icahn School of Medicine at Mount Sinai. This multi-center trial is the largest trial to examine the safety and effectiveness of transcatheter mitral-valve repair in a heart failure population using Abbott’s MitraClip system. It shows this treatment option significantly improves outcomes for patients with heart failure that do not respond to conventional treatments.
The five-year results from the “Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Device” study, or COAPT, were announced Sunday, March 5, in a Late Breaking Clinical Trial presentation at the American College of Cardiology Scientific Sessions Together with World Congress of Cardiology (ACC.23/WCC) in New Orleans, and published in The New England Journal of Medicine.
What would we do if we spotted a hazardous asteroid on a collision course with Earth? Could we deflect it safely to prevent the impact?
Last year, NASA’s Double Asteroid Redirection Test (DART) mission tried to find out whether a “kinetic impactor” could do the job: smashing a 600kg spacecraft the size of a fridge into an asteroid the size of an Aussie Rules football field.
Early results from this first real-world test of our potential planetary defense systems looked promising. However, it’s only now that the first scientific results are being published: five papers in Nature have recreated the impact, and analyzed how it changed the asteroid’s momentum and orbit, while two studies investigate the debris knocked off by the impact.

In a recent article published in the journal Nutrition, researchers in Australia summarized how diet could help decrease low-density lipoprotein cholesterol (LDLc) or triglyceride concentrations in polygenic hypercholesterolemia.

Elevated LDLc or dyslipidemia, including high levels of total cholesterol, increases the risk of cardiometabolic disorders and cardiovascular diseases (CVDs), especially ischemic heart disease (IHD), if not managed in time. Pharmacological treatment is sometimes a prerequisite for cases with complex dyslipidemia with a genetic component. Subsequently, pharmacological research yielded several highly effective drugs based on monoclonal antibody (mAb) therapy, some of which researchers even reviewed in this paper.
Imagine a world with precision medicine, where a swarm of microrobots delivers a payload of medicine directly to ailing cells. Or one where aerial or marine drones can collectively survey an area while exchanging minimal information about their location.
One early step towards realizing such technologies is being able to simultaneously simulate swarming behaviors and synchronized timing—behaviors found in slime molds, sperm and fireflies, for example.
In 2014, Cornell researchers first introduced a simple model of swarmalators—short for “swarming oscillator”—where particles self-organize to synchronize in both time and space. In the study, “Diverse Behaviors in Non-uniform Chiral and Non-chiral Swarmalators,” which published Feb. 20 in the journal Nature Communications, they expanded this model to make it more useful for engineering microrobots; to better understand existing, observed biological behaviors; and for theoreticians to experiment in this field.
