How Generative AI Is Changing Creative Work

Generative AI models for businesses threaten to upend the world of content creation, with substantial impacts on marketing, software, design, entertainment, and interpersonal communications. These models are able to produce text and images: blog posts, program code, poetry, and artwork. The software uses complex machine learning models to predict the next word based on previous word sequences, or the next image based on words describing previous images. Companies need to understand how these tools work, and how they can add value.

Beer is one of the oldest and most popular beverages in the world, with some people loving and others hating the distinct, bitter taste of the hops used to flavor its many varieties. But an especially “hoppy” brew might have unique health benefits. Recent research published in ACS Chemical Neuroscience reports that chemicals extracted from hop flowers can, in lab dishes, inhibit the clumping of amyloid beta proteins, which is associated with Alzheimer’s disease (AD).

Lab discovers new pathway for antimicrobial peptides

2022

Researchers in the Princeton University Department of Chemistry have discovered a new multi-step pathway through which bacteria found in the mammalian gut produce antimicrobial peptides.

The newly identified biosynthetic pathway transforms a biologically inert peptide into structurally complex antibiotics, which they call enteropeptins. Enteropeptins are a class of ribosomally synthesized peptide natural products, referred to as RiPPs.

The core structure of these products is synthesized by the ribosome, which is limited to the 20 canonical amino acids. The Mo Lab discovered and characterized new metalloenzymes capable of converting arginine, a canonical amino acid, into N-methylornithine, a noncanonical amino acid, within enteropeptin.

The Gold In Our Galaxy May Be 10 Billion Years Old, Say Scientists

The hundreds of gold-rich stars discovered in our Milky Way galaxy may have come from smaller galaxies that merged 10 billion years ago, according to new simulations by a supercomputer.

Using the ATERUI II supercomputer in the Center for Computational Astrophysics at the National Astronomical Observatory of Japan, scientists at Tohoku University and the University of Notre Dame developed new simulations of galaxy formation with the highest resolution yet.

The paper was published this week in the Monthly Notices of the Royal Astronomical Society.

Researchers discover unique peptides with anti-cancer potential

A new paper published in Nature Communications presents research on unique peptides with anti-cancer potential.

The research was led by Professor Ashraf Brik and post-doctoral fellows Dr. Ganga B. Vamisetti and Dr. Abbishek Saha from the Schulich Faculty of Chemistry at the Technion—Israel Institute of Technology in Haifa, along with Professor Nabieh Ayoub from the Technion’s Faculty of Biology and Professor Hiroaki Suga from the University of Tokyo.

Peptides are short chains of amino acids linked by peptide bonds, the name given to chemical bonds formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule.

Ultra-thin smartphone touchscreens could be printed like a newspaper

face_with_colon_three circa 2020.

Scientists in Australia have developed a new type of electronic material that is touch-responsive and just a fraction of the thickness of current smartphone screens. This could see it one day find use in next-generation mobile devices, and because of its incredible thinness and flexibility, could be manufactured at large scale using roll-to-roll (R2R) processing like a printed newspaper.

The breakthrough comes from researchers at RMIT University, who began with a material commonly used in today’s mobile touchscreens called indium-tin oxide. This transparent material is highly conductive but does have its shortcomings, chiefly that it is very brittle, so the team sought to give it better pliability by greatly reducing its thickness.

“We’ve taken an old material and transformed it from the inside to create a new version that’s supremely thin and flexible,” says lead researcher Dr Torben Daeneke. “You can bend it, you can twist it, and you could make it far more cheaply and efficiently than the slow and expensive way that we currently manufacture touchscreens.”

Recent searches for light fermionic dark matter by the PandaX-4T collaboration

Posted by Shubham Ghosh Roy in cosmology, particle physics

Teams of astrophysicists worldwide are trying to observe different possible types of dark matter (DM), hypothetical matter in the universe that does not emit, absorb or reflect light and would thus be very difficult to detect. Fermionic DM, however, which would be made of fermions, has so far been primarily explored theoretically.

The PandaX Collaboration, a large consortium of researchers in China involved in the PandaX-4T experiment, has recently carried out a study aimed at extending the sensitive mass window for experiments aimed at directly detecting fermionic DM from above GeV to MeV or even keV ranges.

The team recently published two papers in Physical Review Letters outlining the results of the two searches for the absorption of fermionic DM using data gathered as part of the Panda X-4T experiment, a large-scale research effort aimed at detecting DM using a dual-phase time projection chamber (TPC) in China.

Orbit, an interactive robot, helps teach children on the autism spectrum to develop social appropriateness and emotion via storytelling, physical interaction, and visual communication.

The hand-sized robot smiles and encourages users to press a button on its back, reacting with a beaming smile if pressed gently, and with a sad face if the interaction is too hard.

Hey there. Allow me to introduce you to your new companion, Orbit, a robot you can play with and listen to.

Mapping Brain Connections Reinforces Theories On Human Cognition

17:12 minutes.

After decades of research using sophisticated brain imaging, there’s a growing consensus among neuroscientists that understanding the connections between brain regions may be even more important than the functions of the regions themselves. When it comes to understanding human cognition, the whole is greater than the sum of its parts.
