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.
The investment giant was inspired by Tesla’s Optimus to conduct the report.
A new Goldman Sachs report is revealing that humanoid robots could be a $154 billion-a-year business within the next 15 years, according to a report.
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.
After six decades of examining signals from space, why have we yet to discover evidence of extra-terrestrial life?
Keith’s book “The Contact Paradox: Challenging our Assumptions in the Search for Extraterrestrial Intelligence” is available now — https://geni.us/JFpy.
For the past six decades a small cadre of researchers have been on a quest, as part of SETI, to search for extraterrestrial intelligence. So far, SETI has found no evidence of extraterrestrial life, but with more than a hundred billion stars in our Galaxy alone to search, the odds of quick success are stacked against us.

I live in Manitoba, a province of Canada where all but a tiny fraction of electricity is generated from the potential energy of water. Unlike in British Columbia and Quebec, where generation relies on huge dams, our dams on the Nelson River are low, with hydraulic heads of no more than 30 meters, which creates only small reservoirs. Of course, the potential is the product of mass, the gravitational constant, and height, but the dams’ modest height is readily compensated for by a large mass, as the mighty river flowing out of Lake Winnipeg continues its course to Hudson Bay.
You would think this is about as “green” as it can get, but in 2022 that would be a mistake. There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity?
Construction of large dams began before World War II. The United States got the Grand Coulee on the Columbia River, the Hoover Dam on the Colorado, and the dams of the Tennessee Valley Authority. After the war, construction of large dams moved to the Soviet Union, Africa, South America (Brazil’s Itaipu, at its completion in 1984 the world’s largest dam, with 14 gigawatts capacity), and Asia, where it culminated in China’s unprecedented effort. China now has three of the world’s six largest hydroelectric stations: Three Gorges, 22.5 GW (the largest in the world); Xiluodu, 13.86 GW; and Wudongde, 10.2 GW. Baihetan on the Jinsha River should soon begin full-scale operation and become the world’s second-largest station (16 GW).
