A pair of Danish computer scientists have solved a longstanding mathematics puzzle that lay dormant for decades, after researchers failed to make substantial progress on it since the 1990s.

The abstract problem in question is part of what’s called graph theory, and specifically concerns the challenge of finding an algorithm to resolve the planarity of a dynamic graph. That might sound a bit daunting, so if your graph theory is a little rusty, there’s a much more fun and accessible way of thinking about the same inherent ideas.

Going as far back as 1913 – although the mathematical concepts can probably be traced back much further – a puzzle called the three utilities problem was published.

Salk study is the first to reveal ways cells from the human circulatory system change with age and age-related diseases.

Salk scientists have used skin cells called fibroblasts from young and old patients to successfully create blood vessels cells that retain their molecular markers of age. The team’s approach, described in the journal eLife on September 8, 2020, revealed clues as to why blood vessels tend to become leaky and hardened with aging, and lets researchers identify new molecular targets to potentially slow aging in vascular cells.

“The vasculature is extremely important for aging but its impact has been underestimated because it has been difficult to study how these cells age,” says Martin Hetzer, the paper’s senior author and Salk’s vice president and chief science officer.

India has become the fourth country to successfully flight test hypersonic technology, joining an elite club alongside the US, Russia and China with the ability to develop missiles that can travel several times faster than the speed of sound.

Defence ministry says demonstration vehicle with scramjet engine reached an altitude of 30km and six times the speed of sound.

An endangered type of horse has successfully been cloned by scientists.

Kurt is a newborn Przewalski’s horse, a rare and endangered horse native.

He was born this year on August 6 after experts used genetic material that had been cryopreserved for 40 years.

Kurt’s birth is exciting not only because he’s very cute but because his genetic diversity could help to save the species.

Panasonic is adding another production line to the massive factory it operates with Tesla in Nevada, an expansion that will increase battery cell capacity by 10%.

The Sparks facility, dubbed Gigafactory 1, is the centerpiece of Tesla’s plan to expand global battery capacity and reduce the cost of electric vehicles. Panasonic has been its most important partner in that project, which, based on a recent agreement, should last until at least 2023.

Tesla and Panasonic initially planned for the Gigafactory to have the capacity to produce 35 gigawatt hours of batteries each year. That goal was achieved with 13 production lines. This latest expansion, which was first reported by the Reno Gazette Journal and confirmed by TechCrunch, will add a fourteenth line.

Aiming to make deciding where to travel a bit easier, as COVID-19 continues to spark restrictions and rules for traveling around the United States, United Airlines created an interactive, color-coded map detailing everything travelers need to know ahead of planning a trip.

The map lists everything from whether or not entry into a state is allowed, potential quarantine measures, testing requirements, and even mask mandates for all 50 states and Washington D.C., the company shared with Travel + Leisure. Travelers can see if restaurants, tourist sites, or hotels are open and if there are any specific restrictions in place.

“We know it’s a challenge to keep up with the ever-changing list of travel restrictions, policies and regulations so we are offering a simple, easy tool that helps customers decide where to travel next,” Linda Jojo, the executive vice president for technology and chief digital officer, said in a statement. “By providing the most up-to-date information on the destinations we serve, customers can compare and shop for travel with greater confidence and help them find the destinations that best fit their preferences.”
