For The Better

Researchers have developed highly efficient, on-chip frequency shifters that can convert light in the gigahertz frequency range. The frequency shifters are easily controlled, using continuous and single-tone microwaves.

Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for qua…

An international research team that synthesized a new ultrahard form of carbon glass with a wealth of potential practical applications for devices and electronics. It is the hardest known glass with the highest thermal conductivity among all glass mate…

Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a newborn star collides with the gas and dust around it …

A new statistical analysis supports beliefs that COVID-19 became more lethal in the U.K. in late 2020, while also suggesting that multiple factors — not just the alpha variant of the virus that causes COVID-19 — were to blame.

The Arctic Ocean has been getting warmer since the beginning of the 20th century — decades earlier than records suggest — due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.

Referred to as ‘China’s Venice of the Stone Age’, the Liangzhu excavation site in eastern China is considered one of the most significant testimonies of early Chinese advanced civilization. More than 5000 years ago, the city already had an elaborate wa…
