Delaying the net zero transition could impose significant economic costs

Tue, 03/25/2025 - 8:52am
Delayed and disorderly energy transitions will threaten economic and financial stability whilst also increasing the economic risks from climate change, according to a new study. Conversely, transitions that are started sooner are likely to be more orderly and economically beneficial.

These electronics-free robots can walk right off the 3D-printer

Tue, 03/25/2025 - 8:51am
This a robot can walk, without electronics, and only with the addition of a cartridge of compressed gas, right off the 3D-printer. It can also be printed in one go, from one material.

Device enables direct communication among multiple quantum processors

Fri, 03/21/2025 - 9:13am
Researchers developed a scalable interconnect that facilitates all-to-all communication among many quantum processor modules by enabling each to send and receive quantum information on demand in a user-specified direction. They used the interconnect to demonstrate remote entanglement, a type of correlation that is key to creating a powerful, distributed network of quantum processors.

VR study reveals how pain and fear weaken sense of body ownership

Fri, 03/21/2025 - 9:13am
A study found that when people were told to imagine their virtual bodies in pain, their brains resisted the illusion of ownership. Their findings could provide insights into why some people may struggle with feeling connected to their own bodies, particularly in contexts involving depersonalization or negative physical states.

New AI tool generates high-quality images faster than state-of-the-art approaches

Thu, 03/20/2025 - 11:54am
Researchers developed a hybrid AI approach that can generate realistic images with the same or better quality than state-of-the-art diffusion models, but that runs about nine times faster and uses fewer computational resources. The tool uses an autoregressive model to quickly capture the big picture and then a small diffusion model to refine the details of the image.

New CRISPR tool enables more seamless gene editing -- and improved disease modeling

Thu, 03/20/2025 - 11:52am
Advances in the gene-editing technology known as CRISPR-Cas9 over the past 15 years have yielded important new insights into the roles that specific genes play in many diseases. But to date this technology -- which allows scientists to use a 'guide' RNA to modify DNA sequences and evaluate the effects -- is able to target, delete, replace, or modify only single gene sequences with a single guide RNA and has limited ability to assess multiple genetic changes simultaneously. Now, however, scientists have developed a series of sophisticated mouse models using CRISPR ('clustered regularly interspaced short palindromic repeats') technology that allows them to simultaneously assess genetic interactions on a host of immunological responses to multiple diseases, including cancer.

Novel memristors to overcome AI's 'catastrophic forgetting'

Thu, 03/20/2025 - 11:50am
Memristors consume extremely little power and behave similarly to brain cells. Researchers have now introduced novel memristive that offer significant advantages: they are more robust, function across a wider voltage range, and can operate in both analog and digital modes. Their unique properties could help address the problem of 'catastrophic forgetting,' where artificial neural networks abruptly forget previously learned information.

Producing nuclear fusion fuel is banned in the US for being too toxic, but these researchers found an alternative

Thu, 03/20/2025 - 11:48am
Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method.

Quantum heat dynamics toggled by magnetic fields

Wed, 03/19/2025 - 11:36am
The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, conduct heat. However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange quantum effects begin to dominate. This is particularly true in the realm of quantum materials.

Can online games be an effective intervention to help adolescents reduce substance abuse?

Wed, 03/19/2025 - 11:32am
For adolescents struggling with substance abuse, traditional in-person interventions such as counseling are not always effective, and rural areas often lack access to these services. A researcher is thinking outside the box, aiming to help game designers develop fun, digital games that make ditching bad habits easier by meeting adolescents where they already are: online.
