How were amino acids, one of the key building blocks of life, formed before the origin of life on Earth?      (via sciencedaily.com)     Original source 

The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on the giant precursors of asteroids like Ryugu. Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large disk of gas and dust orbiting it. The dusty material collided to produce rocky material that would eventually grow in size to give large bodies called planetesimals.

A miniature heart in a petri dish: Organoid emulates development of the human heart      (via sciencedaily.com)     Original source 

A team has induced stem cells to emulate the development of the human heart. The result is a sort of 'mini-heart' known as an organoid. It will permit the study of the earliest development phase of our heart and facilitate research on diseases.

Sleight-of-hand magic trick only fools monkeys with opposable thumbs      (via sciencedaily.com) 

An illusion involving a hidden thumb confounds capuchin and squirrel monkeys for the same reason it does humans -- it misdirects expected outcomes of actions they can carry out. However, marmosets have five equidistant digits, and were rarely fooled by the magician. The research adds to evidence that animals struggle to predict movements outside of their own 'biomechanical ability'.

Smart films help to make loudspeakers lighter and more energy-efficient      (via sciencedaily.com)     Original source 

Scientists are developing intelligent materials that are opening up new avenues in sound reproduction technology: lightweight loudspeakers that use far less energy than their conventional counterparts, novel shapes for sound and signal generators and applications involving noise cancelling textiles. The basis for these smart materials are ultrathin silicone films that can act as artificial muscles with their own built-in sensors.

Mathematical model provides bolt of understanding for lightning-produced X-rays      (via sciencedaily.com) 

In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons -- the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why lightning produced X-rays. Now, two decades later, a team has discovered a new physical mechanism explaining naturally occurring X-rays associated with lightning activity in the Earth's atmosphere.

Researchers discover birds with neurotoxin-laden feathers      (via sciencedaily.com) 

An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.

Predatory dinosaurs such as T. rex sported lizard-like lips      (via sciencedaily.com) 

A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.

Scientists analyze sounds emitted by plants      (via sciencedaily.com) 

Researchers have recorded and analyzed sounds distinctly emitted by plants. The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear.

Research into birds killed in window collisions reveals their microbiomes      (via sciencedaily.com) 

Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.

Highly charged ions melt nano gold nuggets      (via sciencedaily.com)     Original source 

Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.

What should we call evolution driven by genetic engineering? Genetic welding, says researcher      (via sciencedaily.com) 

With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.

The powerhouse of the future: Artificial cells      (via sciencedaily.com) 

Researchers identify the most promising advancements and greatest challenges of artificial mitochondria and chloroplasts. The team describes the components required to construct synthetic mitochondria and chloroplasts and identifies proteins as the most important aspects for molecular rotary machinery, proton transport, and ATP production. The authors believe it is important to create artificial cells with biologically realistic energy-generation methods that mimic natural processes; replicating the entire cell could lead to future biomaterials.

First silicon integrated ECRAM for a practical AI accelerator      (via sciencedaily.com) 

The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.
