Millions of space nerds reacted with joy Monday to a study showing the atmosphere of Venus contains phosphine, a chemical byproduct of biological life. But none would have been more thrilled or less surprised by the discovery than the late, great Carl Sagan — who said this day might come more than 50 years ago.

Now best remembered as the presenter of the most-viewed-ever PBS series Cosmos, the author of the book behind the movie Contact, and the guy who put gold disks of Earth music on NASA’s Voyager missions, Sagan actually got his start studying our closest two planets. He became an astronomer after being inspired as a kid by Edgar Rice Burroughs’ space fantasies, set on Mars and Venus.


‘Cosmos’ presenter Carl Sagan was one of the world’s top experts on Venus, and he saw first what scientists have just announced: possible life on Venus.

We’ve had impressive efforts, such as India planting 66 million trees in a day, but that was a large-scale event, which required organizing millions of volunteers. It would be difficult to recreate something like that on a regular basis.

Luckily, a former NASA engineer has developed drones that can plant 100,000 trees per day each.

Multiply that by 165 drones, and we could easily fill the 6-billion-tree gap we face each year.

Returning to the theme of what might be dubbed “UFO Realism” I would like to address a topic that exercises the minds of a lot of UFO conspiracy theorists, namely, reverse engineered alien technologies.

First, is there any evidence at all that any technology we currently have has any extraterrestrial element? For example, one famous claim by Colonel Corso is that much modern technology was derived from the Roswell Incident. To quote the Wikipedia entry the list includes “…particle beam devices, fiber optics, lasers, integrated circuit chips and Kevlar material”, not to mention the transistor itself.

The initial problem with these claims is twofold.

Years ago, our founder Sam Walton famously said, “I have always been driven to buck the system, to innovate, to take things beyond where they’ve been.” It remains a guiding principle at Walmart to this day. From being an early pioneer of universal bar codes and electronic scanning cash registers to our work on autonomous vehicle delivery, we’re working to understand how these technologies can impact the future of our business and help us better serve our customers.

Our latest initiative has us exploring how drones can deliver items in a way that’s convenient, safe, and – you guessed it – fast. Today, we’re taking the next step in our exploration of on-demand delivery by announcing a new pilot with Flytrex, an end-to-end drone delivery company.

Modern construction is a precision endeavor. Builders must use components manufactured to meet specific standards — such as beams of a desired composition or rivets of a specific size. The building industry relies on manufacturers to create these components reliably and reproducibly in order to construct secure bridges and sound skyscrapers.

Now imagine construction at a smaller scale — less than 1/100th the thickness of a piece of paper. This is the nanoscale. It is the scale at which scientists are working to develop potentially groundbreaking technologies in fields like quantum computing. It is also a scale where traditional fabrication methods simply will not work. Our standard tools, even miniaturized, are too bulky and too corrosive to reproducibly manufacture components at the nanoscale.

Researchers at the University of Washington have developed a method that could make reproducible manufacturing at the nanoscale possible. The team adapted a light-based technology employed widely in biology — known as optical traps or optical tweezers — to operate in a water-free liquid environment of carbon-rich organic solvents, thereby enabling new potential applications.

What if you could touch a loved one during a video call—particularly in today’s social distancing era of COVID-19—or pick up and handle a virtual tool in a video game?

Pending user tests and funding to commercialize the new technology, these ideas could become reality in a couple of years after UNSW Sydney engineers developed a new haptic which recreates the .

Haptic technology mimics the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Though the Summer Olympics were postponed, there’s at least one place to see agile hurdlers go for the gold.

You just need a way to view these electron games.

Using a novel optical detection system, researchers at Rice University found that electricity generated by temperature differences doesn’t appear to be affected measurably by placed in its way in nanoscale gold wires, while strain and other defects in the material can change this “thermoelectric” response.

SpaceX is building its Starlink internet network in low Earth orbit. The aerospace company plans to fund its space program by offering affordable, low-latency, broadband internet globally. SpaceX initially plans to deploy 4,409 internet-beaming Starlink satellites, according to a recent letter the company sent to the Federal Communications Commission (FCC). These satellites will operate at altitudes between 550 to 570 kilometers above Earth. To date, there are approximately 708 Starlink satellites already in low Earth orbit.

Company employees are actively private beta testing the Starlink network via user terminals that look like a ‘UFO on a stick’ and Wi-Fi router. – “They show super-low latency and download speeds greater than 100 [megabits] per second [Mbps],” SpaceX Senior Engineer Kate Tice shared during the latest deployment broadcast, “That means our latency is low enough to play the fastest online video games and our download speeds are fast enough to stream multiple HD movies at once.”

Although the SARS-CoV-2 virus has sickened more than 14 million people, bats contract similar viruses all the time without experiencing any known symptoms. Now, the newly sequenced genomes of six species spanning the bat family tree reveal how they’ve been outsmarting viruses for 65 million years. The findings are an “excellent starting point for understanding the superstar immune systems of bats,” says Laurel Yohe, a postdoc at Yale University who studies bat evolution and was not involved with the work. With more than 1400 species, bats are the second most diverse group of mammals on Earth. They live on every continent except Antarctica, and range in size from two to more than 1000 grams. They fly, they echolocate, and some live up to 41 years—a long time for animals of their size. They are also known to carry many different kinds of viruses, including coronaviruses, with no ill effects.
