Some people are at higher risk of developing obesity because they possess genetic variants that affect how the brain processes sensory information and regulates feeding and behavior. The findings from scientists at the University of Copenhagen support a growing body of evidence that obesity is a disease whose roots are in the brain.

Over the past decade, scientists have identified hundreds of different genetic variants that increase a person’s risk of developing obesity. But a lot of work remains to understand how these variants translate into obesity. Now scientists at the University of Copenhagen have identified populations of cells in the body that play a role in the development of the disease—and they are all in the brain.

“Our results provide evidence that biological processes outside the traditional organs investigated in obesity research, such as fat cells, play a key role in human obesity,” says Associate Professor Tune H Pers from the Novo Nordisk Foundation Center for Basic Metabolic Research (CBMR), at the University of Copenhagen, who published his team’s findings in the internationally-recognized journal eLife.

SpaceX’s Starlink satellite internet network has been used in the field by Washington state emergency responders in recent weeks.

Now that people can buy their own Boston Dynamics robots, we’ll have to get used to seeing them out and about.

Electric bicycles have had the best year since ever, so for the average Joe and Jane, it might be somewhat difficult to come across an e-bike that is truly, instantly memorable. Reevo is one of those e-bikes.

There’s some amazing science happening at the South Pole, but some very grandiose claims being made. What’s actually going on?

Scientists typically prefer to work with ordered systems. However, a diverse team of physicists and biophysicists from the University of Groningen found that individual light-harvesting nanotubes with disordered molecular structures still transport light energy in the same way. By combining spectroscopy, molecular dynamics simulations and theoretical physics, they discovered how disorder at the molecular level is effectively averaged out at the microscopic scale. The results were published on 28 September in the Journal of the American Chemical Society.

The double-walled light-harvesting nanotubes self-assemble from molecular building blocks. They are inspired by the multi-walled tubular antenna network of photosynthetic bacteria found in nature. The nanotubes absorb and transport light energy, although it was not entirely clear how. “The nanotubes have similar sizes but they are all different at the molecular level with the molecules arranged in a disordered way,” explains Maxim Pshenichnikov, Professor of Ultrafast Spectroscopy at the University of Groningen.

Amazon CEO Jeff Bezos’ space venture plans to fill in more than 10 acres of wetlands for a rocket manufacturing testing facility south of the Kennedy Space Center Visitor Complex and west of Space Commerce Way.

Blue Origin Florida LLC has applied for a permit from the U.S. Army Corps of Engineers to place fill in 10.32 acres of wetlands, with “secondary impacts” to 7.45 acres of wetlands to build the facility, according to the permit public notice.

The public has until Oct. 13 to comment on the permit application.

Instead of using a credit card or smartphone to pay for your goods, Amazon wants you to use your hands.

In a blog post, the company unveiled its own palm recognition technology, known as Amazon One. The technology, first rolling out in Amazon’s home market of Seattle, will use people’s palms to identify them and combine that with details of the palm, such as lines and ridges, to build a “palm signature.”

“In most retail environments, Amazon One could become an alternate payment or loyalty card option with a device at the checkout counter next to a traditional point of sale system,” Dilip Kumar, vice president, Amazon Physical Retail, wrote in the post. “Or, for entering a location like a stadium or badging into work, Amazon One could be part of an existing entry point to make accessing the location quicker and easier.”

Hubble has released new images of Jupiter as part of OPAL: Outer Planets Atmospheres Legacy program. New storms are forming on the gas giant.

The venerable Hubble Space Telescope has given us another gorgeous picture of Jupiter and its moon Europa. The incredibly sharp image was captured on August 25th, and shows some of the stunning detail in Jupiter’s stormy atmosphere. Hidden in all that stormy activity is something new: a bright white storm plume travelling at about 560 km/h (350 MP/h).

Jupiter was 653 million km (406 million mi) away from Earth when the image was taken. The image is part of OPAL, the Outer Planet Atmospheres Legacy program. Each year, Hubble images the entire planet to watch for changes in the atmosphere and in the storm activity.
