Through a multilevel approach based on AD datasets and a novel chemogenetic method that

Abstract Bovine pericardium (BP) has been used as leaflets of prosthetic heart valves. The leaflets are sutured on metallic stents and can survive 400 million flaps (~10-year life span), unaffected by the suture holes.

It can unify existing

By 2029, there will be 3.6 million computing jobs in the U.S., but there will only be enough college graduates with computing degrees to fill 24% of these jobs. For decades, the U.S. has poured resources into improving gender representation in the tech industry. However, the numbers are not improving proportionately. Instead, they have remained stagnant, and initiatives are failing.

People across the UK, from the Shetland Islands to Somerset and from Norfolk to Northern Ireland, have been treated to a stunning display of the aurora borealis or northern lights recently. But what causes this beautiful phenomena and why has it appeared so far south?

Many people choose to live with a cat for companionship. As a social species, companionship is something we often crave. But this cannot necessarily be said of our feline friends. Domestic cats evolved from a largely solitary species, defending their territory from other cats.

In the months leading up to his 2012 attack that killed 26 people in Newtown, Connecticut, a 20-year-old man exhibited a cascade of concerning behaviors. He experienced worsening anorexia, depression and obsessive-compulsive disorder. His relationships deteriorated, and he became fixated on mass murders.

Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other space telescopes capture X-ray images, and observatories like the Green Bank Telescope, the Very Large Array, the Atacama Large Millimeter Array and dozens of other observatories around the world work at radio wavelengths.

In an ordinary Chicago winter, ice fishermen would still be scampering out onto the frozen stretches of Lake Michigan, toting fishing rods, drills—even pop-up shelters.

The Feynman-Tan relation, obtained by combining Feynman energy relation with Tan's two-body contact, explained excitation spectra of strongly interacting quantum gases of 39K atoms. However, whether Feynman-Tan relation is universal for other atomic species has remained out of reach. Now, this problem has been confirmed by Chinese scientists using high-momentum excitation spectra of interacting Bo

Reuse, share, collect and recycle—in times of faltering supply chains, circular economies are in great demand. When products and materials circulate in closed material flows, it saves resources and avoids waste. Whether this succeeds also depends heavily on the attitudes and behavior of consumers, who use, repair, buy second-hand or share products for as long as possible.

At present, the traditional ways to deal with phenolic organic pollutants and lignin derivatives are mainly physical adsorption and biodegradation. The main disadvantages of these methods are incomplete treatment and long treatment periods. Although new photocatalytic technology uses clean energy and has mild reaction conditions, it also has the disadvantages of slow reaction speed and incomplete
