The Higgs a Particle could have Ended the Universe by now—here’s why we’re still here

Although our universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk—walking on the edge of a very dangerous cliff. And it’s all down to the instability of a single fundamental particle: the Higgs boson.

In new research by me and my colleagues, just accepted for publication in Physical Letters B, we show that some models of the early universe, those which involve objects called light primordial black holes, are unlikely to be right because they would have triggered the Higgs boson to end the cosmos by now.

The Higgs boson is responsible for the mass and interactions of all the particles we know of...

A novel, water-resistant patch-wearable cardioverter-defibrillator (P-WCD) is safe and effective for patients at risk for sudden cardiac arrest, according to a study published in the Aug. 6 issue of the Journal of the American College of Cardiology.

John Hummel, M.D., from The Ohio State University in Columbus, and colleagues assessed the safety and clinical effectiveness of a novel P-WCD. The analysis included 290 patients at risk for sudden cardiac arrest due to ventricular tachycardia/ventricular fibrillation who were not candidates for or refused an implantable defibrillator.

The researchers found that the clinically significant cutaneous adverse device effect rate was 2.30 percent, with no severe adverse effects...

The wing dynamics of flying animal species have been the inspiration for numerous flying robotic systems. While birds and bats typically flap their wings using the force produced by their pectoral and wing muscles, the processes underlying the wing movements of many insects remain poorly understood.

Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL, Switzerland) and Konkuk University (South Korea) recently set out to explore how herbivorous insects known as rhinoceros beetles deploy and retract their wings. The insight they gathered, outlined in a paper published in Nature, was then used to develop a new flapping microrobot that can passively deploy and retract its wings, without the need for extensive actuators.

“Insects, including beetles, are theoretically belie...

Like a supersonic jet being blasted with high-speed winds, Earth is constantly being bombarded by a stream of charged particles from the sun known as solar wind.

Just like wind around a jet or water around a boat, these solar wind streams curve around Earth’s magnetic field, or magnetosphere, forming on the sunward side of the magnetosphere a front called a bow shock and stretching it into a wind sock shape with a long tail on the nightside.

Dramatic changes to the solar wind alter the structure and dynamics of the magnetosphere...
