Is the physical universe independent from us, or is it created by our minds, as suggested by scientist Robert Lanza?

Place one clock at the top of a mountain. Place another on the beach. Eventually, you’ll see that each clock tells a different time. Why?

In his book “The Order of Time,” Italian theoretical physicist Carlo Rovelli suggests that our perception of time — our sense that time is forever flowing forward — could be a highly subjective projection. After all, when you look at reality on the smallest scale (using equations of quantum gravity, at least), time vanishes.

“If I observe the microscopic state of things,” writes Rovelli, “then the difference between past and future vanishes … in the elementary grammar of things, there is no distinction between ‘cause’ and ‘effect.’”

So, why do we perceive time as flowing forward? Rovelli notes that, although time disappears on extremely small scales, we still obviously perceive events occur sequentially in reality. In other words, we observe entropy: Order changing into disorder; an egg cracking and getting scrambled.

For the first time, a team of scientists has created a synthetic single-celled organism that can divide and grow like a regular living cell. This breakthrough could lead to designer cells that can produce useful chemicals on demand or treat disease from inside the body.

This new study, by scientists from the J. Craig Venter Institute (JCVI), the National Institute of Standards and Technology (NIST) and MIT, builds on over a decade’s work in creating synthetic lifeforms. In 2010 a JCVI team created the world’s first cell with a synthetic genome, which they dubbed JCVI-syn1.0.

In 2016, the researchers followed that up with JCVI-syn3.0, a version where the goal was to make the organism as simple as possible. With only 473 genes, it was the simplest living cell ever known – by comparison, an E. coli bacterium has well over 4000 genes. But perhaps it was too simple, because the cells weren’t all that effective at dividing. Rather than uniform shapes and sizes, some of them would form filaments and others wouldn’t fully separate.

‘This means we can start to look at aging as a reversible disease,’ says Prof Shai Efrati; top geriatrician says he is skeptical, and raises concerns.

More than 25 years ago, biologists in Arkansas began to report dozens of bald eagles paralyzed, convulsing, or dead. Their brains were pocked with lesions never seen before in eagles. The disease was soon found in other birds across the southeastern United States. Eventually, researchers linked the deaths to a new species of cyanobacteria growing on an invasive aquatic weed that is spreading across the country. The problem persists, with the disease detected regularly in a few birds, yet the culprit’s chemical weapon has remained unknown.

Today in Science, a team identifies a novel neurotoxin produced by the cyanobacteria and shows that it harms not just birds, but fish and invertebrates, too. “This research is a very, very impressive piece of scientific detective work,” says microbiologist Susanna Wood of the Cawthron Institute. An unusual feature of the toxic molecule is the presence of bromine, which is scarce in lakes and rarely found in cyanobacteria. One possible explanation: the cyanobacteria produce the toxin from a bromide-containing herbicide that lake managers use to control the weed.

The discovery highlights the threat of toxic cyanobacteria that grow in sediment and on plants, Wood says, where routine water quality monitoring might miss them. The finding also equips researchers to survey lakes, wildlife, and other cyanobacteria for the new toxin. “It will be very useful,” says Judy Westrick, a chemist who studies cyanobacterial toxins at Wayne State University and was not involved in the new research. “I started jumping because I got so excited.”

Satellite delivery isn’t exactly cutting-edge tech these days. Lately it feels like SpaceX is doing that every week. Liftoff usually starts with a ground-based rocket, which is expensive and time-consuming to launch. Aevum believes its massive Ravn X drone can do it better, for less money.

At 80 feet long and 18 feet tall, the Ravn X is the world’s biggest drone, says Aevum. Driven by Aevum’s proprietary software, the drone would fly itself to a specified altitude, where it would launch a rocket to deliver a payload of small satellites to low Earth orbit. Click the video above for more on the delivery process.

The launch system is 70% reusable, Aevum said. CEO Jay Skylus hopes to get that close to 100%.

NASA’s Mars Curiosity Rover Martian Solar Day 3060: The Vastness of Time.

1.2 billion pixel panorama of Mars http://bit.ly/sol3060

NASA’s Curiosity rover captured high-resolution panorama of the Martian surface between Sol 3057 (Mar. 12) and Sol 3062 (Mar. 172019). A version without the rover contains 136 images from 34-millimeter Mast Camera; a version with the rover contains 260 images from 100-millimeter telephoto Mast Camera. Both versions are composed of more than 396 images that were carefully stitched.

Humans minds don’t easily comprehend the vast eons of time that separate us from the places we explore in space with robots like Curiosity. Our minds are designed to think in terms of hours, days, seasons, and years, extending up to a duration of our lifetime and perhaps those a few generations before us. When we explore Mars, we’re roving over rocks that formed billions of years ago and many of which have been exposed on the surface for at least tens or hundreds of millions of years. It’s a gap of time that we can understand numerically, but there’s no way to have an innate feel for the incredible ancientness of the planet and Gale Crater.

Today, Curiosity is continuing our drill campaign at Nontron and preparing SAM to study the sample later this week. While that’s ongoing, Mastcam will take a sure-to-be-spectacular 360° mosaic and ChemCam will study the Mont Mercou cliff in front of us (as seen in this Navcam image), including a target called “Font de Gaume.” Font de Gaume cave in France is home to stunning paleolithic cave art of bison, reindeer, and other Ice Age wildlife painted 19–27000 years ago. Even that length of time, at least 15000 years before the pyramids were built in Egypt, is barely 0.0005% of the time back to when Gale Crater formed on Mars.

The mysterious Raider will be the Air Force’s first new bomber in more than 30 years.

The U.S. Air Force and Northrop Grumman have released the first new image of the B-21 Raider bomber in nearly four years. The image, designed to show the plane in hangars at air bases across the country, shows a few more details of the stealthy bomber. According to aviation experts, the new plane looks like the B-2 bomber—with some key differences.

The three images show the plane sitting in hangars at Ellsworth Air Force Base in South Dakota, Whiteman Air Force Base in Missouri, and Dyess Air Force Base in Texas. Ellsworth and Dyess are currently home to B-1B Lancer bombers, while Whiteman is home to America’s fleet of B-2A Spirit bombers. The B-21 Raider will eventually replace both types.

Airspeeder wants to be the “first electric flying car race,” its CEO told Insider. It also wants you to know flying cars are closer than you think.

The sudden prevalence of an artery in the forearm is evidence that we’re still very much a work in progress.
