Single Cells Evolve Large Multicellular Forms in Just Two Years

Posted by in category: futurism

It’s easy for us, as the vast architectures of cells that we are, to take it for granted that multicellularity is an unqualified advantage. But as far as we can tell from fossils, life seems to have been cheerfully unicellular for its first billion years. And even today, there are far more unicellular organisms than multicellular ones on the planet.


Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms.

Winged Microchip Is Smallest-Ever Human-Made Flying Structure — The Size of a Grain of Sand

Posted by in categories: biotech/medical, computing

The size of a grain of sand, dispersed microfliers could monitor air pollution, airborne disease, and environmental contamination.

Northwestern University engineers have added a new capability to electronic microchips: flight.

Immune Cells in the Brain Share the Work

Posted by in categories: biotech/medical, neuroscience

Microglia immune cells can join together to form networks when needed, a new study reports. However, certain mutations associated with Parkinson’s disease can impair this process.

Look: Rare ‘Einstein Ring’ spotted

Posted by in category: space

NASA’s Hubble Space Telescope captured a cluster of distant galaxies surrounded in reflected light — an illusion first predicted by Einstein over a century ago.

A Particle Physics Experiment Might Have Directly Observed Dark Energy

Posted by in categories: cosmology, particle physics

In a new study, a team of researchers proposed that Dark Matter detectors could also search for the elusive force that is causing our Universe to expand (Dark Energy)!


About 25 years ago, astrophysicists noticed something very interesting about the Universe. The fact that it was in a state of expansion had been known since the 1920s, thanks to the observation of Edwin Hubble. But thanks to the observations astronomers were making with the space observatory that bore his name (the Hubble Space Telescope), they began to notice how the rate of cosmic expansion was getting faster!

Are we living in a baby universe that looks like a black hole to outsiders?

Posted by in categories: cosmology, physics

A new paper takes a deep dive into primordial black holes that were formed as a part of the early universe when there were still no stars or galaxies. Such black holes could account for strange cosmic possibilities, including baby universes and major features of the current state of the cosmos like dark matter.

To study the exotic primordial black holes (PBHs), physicists employed the Hyper Suprime-Cam (HSC) of the huge 8.2m Subaru Telescope operating near the 4,200 meter summit of Mt. Mauna Kea in Hawaii. This enormous digital camera can produce images of the entire Andromeda galaxy every few minutes, helping scientists observe one hundred million stars in one go.

Urban Aeronautics ‘CityHawk’ Is World’s First Hydrogen-Powered eVTOL Vehicle

Posted by in categories: futurism, transportation

Israel’s Urban Aeronautics is the latest to enter the growing Electric Vertical Take-Off and Landing (eVTOL) airspace with an aircraft that, at the very least, has a pretty cool name.

The “CityHawk” has been referred by Autoevolution as the “world’s first wingless” eVTOL vehicle. The rotors of other flying EVs like the Volocopter 2X and New Future Transportation ASKA protrude from body. But the CityHawk’s “Fancraft” system features two, counter-rotating ducted rotors partially enclosed behind and in front of the cockpit.

NASA VIPER rover and Astrobotic Griffin lander select moon landing site for 2023

Posted by in categories: robotics/AI, space travel

The NASA VIPER rover – a precursor mission to human landings in the south polar region of the Moon, and a mission started in 2019 under the Commercial Lunar Payload Services program – has had its landing site selected for its 2023 mission. The rover, known as the Volatiles Investigating Polar Exploration Rover, is now scheduled to land west of Nobile Crater in the lunar south polar region sometime in late 2023 after its launch aboard a SpaceX Falcon Heavy rocket.

This mission, costing $660 million, is one of several that will launch to the Moon in the next two years and is notable for being the first NASA rover to launch as a customer aboard a commercial lander.

The golf cart-sized VIPER rover will be mounted onto a Griffin lunar lander built by Astrobotic, a Pittsburgh-based company developing various lunar spacecraft that can carry payloads into lunar orbit or onto the lunar surface. After landing, VIPER will roll out onto the lunar surface with the help of a pair of ramps mounted on the lander and conduct checkouts before starting its surface mission.
