In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed elsewhere in the Solar System. However, as atmospheric temperatures on our planet decrease at altitude, on Pluto they heat up at altitude as a result of solar radiation.
So where does this ice come from? An international team led by CNRS scientists* conducted this exploration. They first determined that the “snow” on Pluto’s mountains actually consists of frozen methane, with traces of this gas being present in Pluto’s atmosphere, just like water vapour on Earth.
Then, to understand how the same landscape could be produced in such different conditions, they used a climate model for the dwarf planet, which revealed that due to its particular dynamics, Pluto’s atmosphere is rich in gaseous methane at altitudes. As a result, it is only
A roundup of notable gifts compiled by the Chronicle:
Nike co-founder Phil Knight gave $900.7 million to his and wife Penelope’s foundation. The couple primarily support scientific and medical research at the University of Oregon, Oregon Health and Science University, and other large institutions. They have also given extensively to Stanford University, where Phil Knight earned an MBA in 1962.
University of Oregon
Phil Knight gave $300 million for ongoing support for many of the university’s programs to which he has donated in recent years. With this latest gift, he and his wife, Penelope, have donated at least $1.1 billion to the university since 2007, with much of it directed to scientific research and related programs.
Phil Knight earned a journalism degree from the university in 1959 and went on to co-found Nike, the sports-apparel company.
Kummer Institute Foundation
Fred and June Kummer gave $300 million to establish

Apple will no longer include a complimentary pair of wired headphones or a power adapter with new iPhones, the company announced Tuesday as it unveiled the iPhone 12, in an effort to cut down on packaging and reduce emissions.
The iPhone 12 will only come with a USB-C to Lightning cable for charging.
You’ll have to buy a $19 USB-C charging brick separately if you want to use the cable in the box, though you can still charge your phone with any old iPhone charger with a Lightning connector.
Earpods will cost another $19 if you don’t already have a pair or use wireless Airpods.
Apple says the move is part of the company’s effort to become 100% carbon neutral by 2030.
Removing accessories, Apple says, will use fewer raw materials and thinner packaging, which allows Apple to put 70% more units on a single shipping pallet
A new crew of three astronauts are launching to the International Space Station late tonight, blasting off on a Russian Soyuz rocket out of Kazakhstan. The trio are heading to the station about a month ahead of SpaceX’s next crewed Dragon launch, which will bring another set of four astronauts aboard the ISS in mid-November.
Heading up on this Soyuz flight are two Russian cosmonauts — Sergey Ryzhikov and Sergey Kud-Sverchkov — and NASA astronaut Kate Rubins, on her second trip to space. The trio will join three crew members who have been living on the ISS since April: Russian cosmonauts Anatoly Ivanishin and Ivan Vagner and NASA astronaut Chris Cassidy. However, their living arrangement won’t last long. Cassidy and his cosmonaut crew mates are slated to head back to Earth on October 21st, riding inside the Soyuz capsule that brought them to the space station.
Moles stop growing when they reach a certain size due to normal interactions between cells, despite having cancer-associated gene mutations, says a new study published today in eLife.
The findings in mice could help scientists develop new ways to prevent skin cancer growth that take advantage of the normal mechanisms that control cell growth in the body.
Mutations that activate the protein made by the BRAF gene are believed to contribute to the development of skin cancer. However, recent studies have shown that these mutations do not often cause skin cancer, but instead result in the formation of completely harmless pigmented moles on the skin. In fact, 90% of moles have these cancer-linked mutations but never go on to form tumours. “Exploring why moles stop growing might lead us to a better understanding of what goes wrong in skin cancer,” says lead author Roland Ruiz-Vega, a postdoctoral researcher at
CAPE CANAVERAL, Fla. — Jeff Bezos’ Blue Origin space company launched a New Shepard rocket for a seventh time from a remote corner of Texas on Tuesday, testing new lunar-landing technology for NASA that could help put astronauts back on the moon.
The entire flight — barely skimming space with a peak altitude of 66 miles (106 kilometers) — lasted just 10 minutes. The booster landed vertically back at the launch complex after liftoff, and the capsule followed, parachuting onto the desert floor.
The capsule carried science experiments, including 1.2 million tomato seeds that will be distributed to schoolchildren around the U.S. and Canada, and tens of thousands of children’s postcards with space-themed drawings that will be returned to the young senders.
NASA’s navigation equipment for future moon landings was located on the booster. The sensors and computer — tested during the booster’s descent and touchdown — will hitch another
Shares of Loop Industries (LOOP) – Get Report lost a third of their market value on Tuesday after the activist investment group Hindenburg published a report lambasting the plastics-recycling company and said it took a short position.
The investment firm said it interviewed former employees, competitors, industry experts and company partners as part of its investigation and concluded that Loop is “smoke and mirrors with no viable technology.”
Loop, Terrebonne, Quebec, didn’t immediately return a request for comment.
Former employees told Hindenburg that Loop operated two labs, one reserved for its “two twenty-something lead scientist brothers and their father” and one run by rank-and-file scientists who were unable to replicate results.
The investment firm said that a Loop employee told Hindenburg that scientists were pressured by Chief Executive Daniel Solomita to “lie about the results of the company’s process internally. We have obtained internal documents and photographs to
