Using Sound To Control Enzymatic Reactions

Posted by in categories: chemistry, energy, physics

Unhackneyed compartmentalization generated by audible sound allows the enzyme reactions to be controlled spatiotemporally.

Spatiotemporal regulation of multistep enzyme reactions through compartmentalization is essential in studies that mimic natural systems such as cells and organelles. Until now, scientists have used liposomes, vesicles, or polymersomes to physically separate the different enzymes in compartments, which function as ‘artificial organelles’. But now, a team of researchers led by Director KIM Kimoon at the Center for Self-assembly and Complexity within the Institute for Basic Science in Pohang, South Korea successfully demonstrated the same spatiotemporal regulation of chemical reactions by only using audible sound, which is completely different from the previous methods mentioned above.

Although sound has been widely used in physics, materials science, and other fields, it has rarely been used in chemistry. In particular, audible sound (in the range of 20–20,000 Hz) has not been used in chemical reactions so far because of its low energy. However, for the first time, the same group from the IBS had previously successfully demonstrated the spatiotemporal regulation of chemical reactions through a selective dissolution of atmospheric gases via standing waves generated by audible sound back in 2020.

Should we just be blasting out to the cosmos?


Two new messages will give away our location, one to TRAPPIST-1. But it brings up a few questions which question if METI is so smart after all.

Drone swarms can now fly autonomously through thick forest

Posted by in categories: drones, robotics/AI

A swarm of 10 bright blue drones lifts off in a bamboo forest in China, then swerves its way between cluttered branches, bushes and over uneven ground as it autonomously navigates the best flight path through the woods.

The experiment, led by scientists at Zhejiang University, evokes scenes from —and the authors in fact cite films such as “Star Wars,” “Prometheus” and “Blade Runner 2049” in the opening of their paper published Wednesday in the journal Science Robotics.

“Here, we take a step forward (to) such a future,” wrote the team, led by Xin Zhou.

30 years after Intelsat VI rescue, Northrop Grumman aims to make in-space servicing a permanent reality

Posted by in categories: robotics/AI, space

On 7 May 1992, Space Shuttle Endeavour lifted off on her first voyage at 23:40 UTC from Pad-B at the Kennedy Space Center in Florida. Her target: Intelsat VI F-3 (now known as Intelsat 603). The goal: rendezvous with, repair, and re-release the satellite.

In the now-30 years since that mission, on-orbit satellite repair and servicing have largely languished — save for the five Hubble servicing missions Endeavour and the Shuttle fleet would conduct after STS-49.

Research Links Investment In Automation To Rising Mortality Rates

Posted by in categories: employment, robotics/AI

“We provide a lot of evidence to bolster the case that this is a causal relationship, and it is driven by precisely the industries that are most affected by aging and have opportunities for automating work,”

“For decades, manufacturers in the United States have turned to automation to remain competitive in a global marketplace, but this technological innovation has reduced the number of quality jobs available to adults without a college degree—a group that has faced increased mortality in recent years,”

Scientists engineer a bacteria to produce a drug used to treat Parkinson’s disease

Posted by in categories: biotech/medical, engineering, genetics, neuroscience

The results of the study could lead to new treatment options. In a groundbreaking new study published in the journal Nature on Thursday, researchers have compared the brain cells of patients who had died from either Parkinson’s disease or dementia to people unaffected by the disorders and found which brain cells are responsible for both conditions.


A team of researchers has created a bacteria that can produce a steady and consistent source of medicine inside a patient’s gut, suggesting the possibility for genetically edited bacteria to be an efficient Parkinson’s disease treatment.

Apple, Google and Microsoft team up on passwordless logins

Posted by in categories: cybercrime/malcode, mobile phones

On the “World Password Day”, which was on May 5, Google, Microsoft and Apple joined hands to “kill” the password.

The three technology giants have vowed to create a future where your phone will be the primary source of online authentication. The new standard is being referred to as “muti-device FIDO credential”.

In a rare show of alliance, Apple, Google and Microsoft have joined forces to expand support for passwordless logins across mobile, desktop and browsers.
