A ResNet mini architecture for brain age prediction

The human brain undergoes age-related structural and functional changes throughout life, varying among individuals and groups. Predicting brain age is valuable for assessing brain development, aging, and disease diagnosis in neurology. Various machine learning methods have been employed for this purpose, the paper proposes a compact ResNet-based architecture called ResNet mini to address memory resource constraints.

BEHAVIOR Vision Suite: Customizable Dataset Generation via Simulation

Systematically evaluating computer vision models under diverse conditions necessitates extensive data with tailored labels, which real-world datasets often lack. While synthetic data generators offer potential, they frequently lack quality, diversity, and realistic physical properties. Introducing the BEHAVIOR Vision Suite (BVS), a toolkit for generating customized synthetic data, based on the BEHAVIOR-1K benchmark, aimed at enhancing evaluation of computer vision models.

New method of wavefunction matching helps solve quantum many-body problems

An international team of researchers has developed a new method called wavefunction matching to solve quantum many-body problems in strongly interacting systems. This approach overcomes limitations encountered in stochastic methods like Monte Carlo simulations when sign oscillations occur. Using this method, the team accurately calculated the masses and radii of nuclei up to mass number 50, with results aligning with measurements, as reported in Nature.

Cameras inspired by insect eyes could give robots a wider view

Cameras inspired by insect compound eyes offer wide fields of view without expensive lenses, potentially providing affordable and lightweight visual sensors for robots and driverless cars. Replicating the architecture of insect eyes, researchers at the Hong Kong University of Science and Technology developed nanowires from perovskite crystals, eliminating the need for precise lenses.

How to kill the ‘zombie’ cells that make you age

Senescent cells, akin to zombies, linger in various organs, emitting harmful signals that deteriorate health as people age. Researchers have long sought ways to eliminate these cells, with promising results emerging from studies using compounds like dasatinib and quercetin. Recent animal studies and clinical trials are exploring diverse approaches, including genetic reprogramming and immune cell engineering, with around 20 trials underway to combat age-related ailments such as Alzheimer’s and lung disease.

Drug Overdose Deaths in America Have Finally Stopped Climbing

Preliminary data from the Centers for Disease Control and Prevention indicates a slight decrease in total drug overdose deaths in the United States in 2023, including those linked to fentanyl and synthetic opioids. While deaths related to some other drugs rose and certain regions experienced increased fatalities, this marks the first time in a while that America's drug overdose crisis has not worsened overall.

Testosterone/CVD Risk Debate Revived by New Meta-Analysis

A recent systematic literature review complicates the ongoing debate surrounding testosterone's association with the risk of myocardial infarction, stroke, cardiovascular death, and all-cause mortality.

Orcas have attacked and sunk another boat in Europe — and experts warn there could be more attacks soon

A group of orcas in southwest Europe, known for attacking boats, sank a 50-foot sailing yacht in the Strait of Gibraltar by tearing open its hull. This incident marks the fifth time these killer whales have caused a ship to sink in the past three years.
