The invention could enhance the speed of electronic devices and improve security screening technology.

Chinese scientists have conceived of a new method for generating laser-like light that could significantly enhance the communication speed of everyday electronics, according to a report by the South China Morning Post.

The new device that makes this light possible is known as a free-electron laser, and it has been developed by scientists from the Shanghai Institute of Optics and Fine Mechanics under the Chinese Academy of Sciences.

In the U.S. alone, CO₂ emissions from cremations surpassed 360,000 metric tonnes in 2020.

A French woman has started a strange but environmentally friendly funeral service dubbed ‘Corbicyclette,’ which is French for a bicycle hearse.

An unusual “cargo bike” could shake up the funeral industry in France, Euronews reported on Wednesday.

The fundamental laws of friction remain a mystery to this day.

Researchers at the NYU Tandon School of Engineering have discovered a fundamental friction law that is leading to the design of two-dimensional materials capable of minimizing energy loss, according to a press release from the institution published on Thursday.

Nobody has known what exists in this region of space known as the “Zone of Avoidance.” Now astronomers edge one step closer.

Astronomers have found a giant “extragalactic structure” concealed behind the Milky Way, according to a new study published in Arxiv.

The study explained that the zone of avoidance (ZOA) does not allow clear optical observations of extragalactic sources behind the Milky Way.

Beyond passenger cars and pickups: 5 questions answered about electrifying trucks.

As part of its effort to reduce air pollution and cut greenhouse gas emissions contributing to climate change, California is pursuing aggressive policies to promote clean trucks. The state already requires that by 2035, all new cars and other light-duty vehicles sold in the state must be zero emission. Its powerful Air Resources Board has adopted rules requiring that most trucks be zero emission by 2035 and is now proposing that all trucks sold by 2040 must be zero emission. The Conversation asked a panel of transportation experts from the University of California, Davis, what’s involved in such a rapid transition.

What is driving the mulitverse theory? Are the multiverse stories only a sticky-plaster solution to the Big Bang theory problem? Leading thinkers Sabine Hossenfelder, Roger Penrose and Michio Kaku debate.

00:00 Introduction.
02:22 Michio Kaku | Multiverse theory has now dominating cosmology; it is unavoidable.
06:03 Sabine Hossenfelder | Believing in the multiverse is the logical equivalent to believing in God.
07:57 Roger Penrose | Universes are sequential and so are not independent worlds.
16:36 Theme 1 | Do scientifc theories need to be testable?
28:45 Theme 2 | Are tales of the multiverse solutions to the Big Bang theory in trouble?
42:49 Theme 3 | Will theories of the universe always be bound by untestable elements?

It helps if you know what to look for.

Searching for alien life has never been easier. Scientists are finally getting closer to discovering extraterrestrial life in the universe using a combination of data and tools.

A century ago, the German physicists Otto Stern and Walther Gerlach carried out an experiment that gave an important credibility boost to the new-fangled notion of quantum mechanics. But as Hamish Johnston discovers, their now-famous experiment succeeded even if the physics on which it was based wasn’t quite right.
