Why ‘blobology’ is the new hot topic in science
Posted by Steve Nichols in categories: biotech/medical, science
Scientists have created an image which zooms in to a tiny section inside a cell. This is not a simulation, it is the real thing. As you run the video, you will see the section highlighted in green and then thin yellow tubes inside it. These are strands of the body’s clotting agent ready to be transported to the site of a wound.

Will China lead the world in AI by 2030?
Posted by Derick Lee in categories: ethics, robotics/AI
But observers warn that there are several factors that could stymie the nation’s plans, including a lack of contribution to the theories used to develop the tools underpinning the field, and a reticence by Chinese companies to invest in the research needed to make fundamental breakthroughs.
The country’s artificial-intelligence research is growing in quality, but the field still plays catch up to the United States in terms of high-impact papers, people and ethics.

Artificial Tree Can Suck Up As Much Air Pollution As A Small Forest
Posted by Shailesh Prasad in category: sustainability
Mexico-based startup Biomitech has developed an artificial tree that it claims is capable of sucking up the equivalent amount of air pollution as 368 living trees. In doing so, it could be a game-changer for polluted cities lacking enough free space to plant a forest of real trees.

New Experiment Just Placed a Major Constraint on The Mysterious Force of Dark Energy
Posted by Shailesh Prasad in categories: cosmology, physics
The Universe is expanding, and that expansion is speeding up over time. These two facts have been well established through observation, but we don’t know what’s causing that expansion. It seems to be some mysterious, unknown energy that acts like the opposite of gravity.
We call this hypothetical energy “dark energy”, and it’s been calculated to constitute around 72 percent of all the stuff that makes up the Universe. We don’t know what it actually is. But a new experiment has just allowed us to rule out one more thing that it isn’t: a new force.
“This experiment, connecting atomic physics and cosmology, has allowed us to rule out a wide class of models that have been proposed to explain the nature of dark energy, and will enable us to constrain many more dark energy models,’‘said physicist Ed Copeland of the University of Nottingham.

New Tech Puts NASA One Step Closer to Fueling Spacecraft in Space
Posted by Shailesh Prasad in categories: robotics/AI, space
NASA just successfully demonstrated the first of three tools designed to refuel spacecraft in space, right outside of the International Space Station.
The space agency’s Robotic Refuelling Mission 3 was able to unstow a special adapter that can hold super-cold methane, oxygen or hydrogen, and insert it into a special coupler on a different fuel tank.
Future iterations of the system could one day allow us to gas up spacecraft with resources from distant worlds, such as liquid methane as fuel. And that’s a big deal, since future space explorations to far away destinations such as the Moon and Mars will rely on our ability to refuel after leaving Earth’s gravity.

‘Electron pairing’ found well above superconductor’s critical temperature
Posted by Saúl Morales Rodriguéz in categories: computing, mobile phones, particle physics
Physicists have found “electron pairing,” a hallmark feature of superconductivity, at temperatures and energies well above the critical threshold where superconductivity happens.
Rice University’s Doug Natelson, co-corresponding author of a paper about the work in this week’s Nature, said the discovery of Cooper pairs of electrons “a bit above the critical temperature won’t be ‘crazy surprising’ to some people. The thing that’s more weird is that it looks like there are two different energy scales. There’s a higher energy scale where the pairs form, and there’s a lower energy scale where they all decide to join hands and act collectively and coherently, the behavior that actually brings about superconductivity.”

Study identifies main culprit behind lithium metal battery failure
Posted by Saúl Morales Rodriguéz in category: nanotechnology
A research team led by the University of California San Diego has discovered the root cause of why lithium metal batteries fail—bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as “dead” or inactive lithium that the battery can no longer access.
The discovery, published Aug. 21 in Nature, challenges the conventional belief that lithium metal batteries fail because of the growth of a layer, called the solid electrolyte interphase (SEI), between the lithium anode and the electrolyte. The researchers made their discovery by developing a technique to measure the amounts of inactive lithium species on the anode—a first in the field of battery research—and studying their micro- and nanostructures.
The findings could pave the way for bringing rechargeable lithium metal batteries from the lab to the market.
