Oldest modern human genomes sequenced

Researchers analyzed nuclear genomes of ancient European specimens to shed light on the genetics of early Europeans and their interactions with Neandertals. The study reveals a small, isolated group that interbred with Neandertals but left no present-day descendants.

Superflares once per century

A new study reveals that sun-like stars experience superflares approximately once per century, releasing massive amounts of energy in short periods. This finding suggests that the Sun's long-term behavior may be more frequent than previously thought, with implications for forecasting dangerous space weather.

Study sheds light on the origin of the genetic code

A recent study revises our understanding of the universal genetic code's evolution, suggesting that early life preferred smaller amino acids over larger ones. The researchers found that amino acids with aromatic ring structures were incorporated into the code later than previously thought, offering clues about other extinct genetic codes.

Spirals and waves

Researchers Navdeep Rana and Ramin Golestanian investigated non-reciprocal interaction and defect formation in active systems, finding well-ordered wave patterns emerge when non-reciprocity exceeds a certain level. This property opens avenues for applications of non-reciprocal active matter systems.

Deep learning model accurately diagnoses COPD

A deep learning model developed by researchers at San Diego State University can accurately diagnose chronic obstructive pulmonary disease (COPD) using a single inhalation lung CT scan. The study found that the model performed similarly to traditional two-phase CT measurements, with added clinical data improving accuracy.

More dense, populated neighborhoods inspire people to walk more

A national study found that walkable neighborhoods increase walking by 23% due to factors like density of people, roads, and amenities. Living in a walkable area also reduces the chance of no transit use, while vigorous exercise is not necessarily linked to neighborhood walkability.

GQ GMC-500Plus Geiger Counter logs beta, gamma, and X-ray levels for environmental monitoring, training labs, and safety demonstrations.

What brings richness to sparkling wines?

Researchers have discovered 11 probable kokumi compounds in sparkling wines, which may contribute to their rich, full-bodied taste. The study identified these compounds through a combination of computer simulations and wine tastings, paving the way for further investigation into the molecular basis of kokumi sensation in wines.

Study reveals short term safety of active monitoring for DCIS

The study found that women who underwent active monitoring had a lower rate of invasive cancer (4.2%) compared to those who received surgery and radiation (5.9%). The researchers suggest that active monitoring may be a safe alternative for treating low-risk DCIS, especially when combined with hormone-blocking treatment.

New data storage method proposed: hybrid-layer optical data storage

Researchers have introduced a novel concept called hybrid-layer optical data storage (ODS) that uses high-orthogonality random meta-channels to encode data into both physical and virtual layers. This approach has shown promising results, achieving a storage density of 2.5 Tbit cm⁻³.

Graz language database improves automatic speech recognition of Austrian German

Researchers at Graz University of Technology developed a new database to improve speech recognition of Austrian German using speech data from 38 speakers. They found that traditional HMM-based systems are more robust for short sentences and dialectal language, while transformer-based models excel with longer sentences and context.

“Us” vs. “them” biases plague AI, too

A new study finds that large language models are prone to social identity biases, favoring their perceived ingroup while expressing negativity toward outgroups. However, the researchers discovered that carefully selecting the training data can reduce these biases, suggesting promising directions for improving AI development and training.
