Heaviest black hole merger is among three recent gravitational wave discoveries

Scientists observed what appears to be a bulked-up black hole tangling with a more ordinary one. The research team, which includes physicists from the University of Maryland, detected two black holes merging, but one of the black holes was 1 1/2 times more massive than any ever observed in a black hole collision. The researchers believe the heavier black hole in the pair may be the result of a previous merger between two black holes.This type of hierarchical combining of black holes has been hypothesized in the past but the observed event, labeled GW190521, would be the first evidence for such activity. The Laser Interferometer Gravitational-Wave Observatory (LIGO) Scientific Collaboration (LSC) and Virgo Collaboration announced the discovery in two papers published September 2, 2020, in the journals Physical Review Letters and Astrophysical Journal Letters.

Has Earth's oxygen rusted the Moon for billions of years?

Researcher proposes universal mechanism for ejection of matter by black holes

Black holes can expel a thousand times more matter than they capture. The mechanism that governs both ejection and capture is the accretion disk, a vast mass of gas and dust spiraling around the black hole at extremely high speeds. The disk is hot and emits light as well as other forms of electromagnetic radiation. Part of the orbiting matter is pulled toward the center and disappears behind the event horizon, the threshold beyond which neither matter nor light can escape. Another, much larger, part is pushed further out by the pressure of the radiation emitted by the disk itself.

New anode material could lead to safer fast-charging batteries

Scientists at UC San Diego have discovered a new anode material that enables lithium-ion batteries to be safely recharged within minutes for thousands of cycles. Known as a disordered rocksalt, the new anode is made up of earth-abundant lithium, vanadium and oxygen atoms arranged in a similar way as ordinary kitchen table salt, but randomly. It is promising for commercial applications where both high energy density and high power are desired, such as electric cars, vacuum cleaners or drills.

Opinion: Why a UK 'cycling and walking revolution' won't reduce car travel

The UK prime minister, Boris Johnson, has announced £2 billion to create thousands of miles of protected bike lanes and pedestrian space. There are lots of good reasons to encourage walking and cycling—active travel, as it's called. The pandemic necessitates social distancing on public transport, which means buses and trains have to ferry fewer passengers per journey. Cycling and walking are healthier alternatives and in the longer term, both have a part to play in cutting carbon emissions from the transport system, as well as improving urban air quality.

House hunters are rarely told the home energy rating—little wonder the average is as low as 1.8 stars

Predictive placentas: Using AI to protect mothers' future pregnancies

After a baby is born, doctors sometimes examine the placenta—the organ that links the mother to the baby—for features that indicate health risks in any future pregnancies. Unfortunately, this is a time-consuming process that must be done by a specialist, so most placentas go unexamined after the birth. A team of researchers from Carnegie Mellon University (CMU) and the University of Pittsburgh Medical Center (UPMC) developed a machine learning approach to examine placenta slides so more women can be informed of their health risks.

Travel site aggregators face challenges when compared to airlines that market directly
