AI tailors artificial DNA for future drug development

With the help of an AI, researchers have succeeded in designing synthetic DNA that controls the cells' protein production. The technology can contribute to the development and production of vaccines, drugs for severe diseases, as well as alternative food proteins much faster and at significantly lower costs than today.

525-million-year-old fossil defies textbook explanation for brain evolution

According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom. Combining detailed anatomical studies of the fossilized nervous system with analyses of gene expression patterns in living descendants, they conclude that a shared blueprint of...

Stop counting cups: There's an ocean of difference in our water-drinking needs

A new study of thousands of people reveals a wide range in the amount of water people consume around the globe and over their lifespans, definitively spilling the oft-repeated idea that eight, 8-ounce glasses meet the human body's daily needs. Differences in environment, body composition and activity level contribute to daily water turnover of as little as 1 liter and as much as 10 liters.


A radical new approach in synthetic chemistry

Scientists have measured how unpaired electrons in atoms at one end of a molecule can drive chemical reactivity on the molecule's opposite side. This work shows how molecules containing these so-called free radicals could be used in a whole new class of reactions.

Gene that guides earliest social behaviors could be key to understanding autism

A new animal study points to a gene that is important for the earliest development of basic social behaviors. The work also suggests that exposure to certain drugs and environmental risk factors during embryonic development can cause changes to this gene, leading to alterations in social behavior that are similar to those found in individuals who have autism.

Pocket feature shared by deadly coronaviruses could lead to pan-coronavirus antiviral treatment

Scientists have discovered why some coronaviruses are more likely to cause severe disease, which has remained a mystery, until now. Researchers say their findings could lead to the development of a pan-coronavirus treatment to defeat all coronaviruses -- from the 2002 SARS-CoV outbreak to Omicron, the current variant of SARS-CoV-2, as well as dangerous variants that may emerge in future.


A simpler path to better computer vision

Research finds using a large collection of simple, un-curated synthetic image generation programs to pretrain a computer vision model for image classification yields greater accuracy than employing other pretraining methods that are more costly and time consuming, and less scalable.

Gully erosion prediction tools can lead to better land management

Soil erosion is a significant problem for agricultural production, impacting soil quality and causing pollutants to enter waterways. Among all stages of soil erosion, gully erosion is the most severe phase, where large channels are carved through the field. Once gullies develop, they are challenging to manage through tiling; they require a more comprehensive approach along the impacted area....

Discovery could lead to new drugs to block protein that fuels bowel cancer

Scientists have revealed the inner workings of a key protein involved in a wide range of cellular processes -- potentially paving the way for better and less toxic cancer drugs. Using Nobel Prize-winning microscopy techniques, the researchers revealed how the tankyrase protein switches itself on and off by self-assembling into 3D chain-like structures.

Drug triggers immune cells to attack prostate cancer

A single drug compound simultaneously attacks hard-to-treat prostate cancer on several fronts, according to a new study in mice and human cells. It triggers immune cells to attack, helps the immune cells penetrate the tumor, and cuts off the tumor's ability to burn testosterone as fuel, according to new research.
