Detection and prediction of anomalous behaviors of enterprise’s employees based on data-mining and optimization algorithm

Internal employees pose significant security challenges. By analyzing behavioral data, data-mining creates a knowledge graph and models for detecting anomalies and predicting resignations. The SBP model detects anomalous behaviors, and the SLSTM model predicts resignations, improving threat detection and reducing internal threats.

Safetywashing: Do AI Safety Benchmarks Actually Measure Safety Progress?

As AI advances, AI safety research is gaining interest but lacks clear definitions and measurements. A meta-analysis shows many safety benchmarks correlate with general AI capabilities, risking "safetywashing." The study proposes distinct, empirical safety metrics to clarify and advance AI safety research.

New technique measures superconductivity at very high pressures

Scientists from Germany and the US have developed a technique to measure superconductivity in sulfur at high pressures, offering insights into high-pressure superconductors. This advancement, published in Physical Review Letters, aims to further understand and discover materials with higher critical temperatures for practical electricity transport.

Spins hop between quantum dots in new quantum processor

Researchers in the Netherlands have unveiled a quantum computing system using the spins of holes in germanium quantum dots, based on a 1998 proposal. This system could offer significant advantages over current technologies like superconducting circuits and trapped ions, which face scalability and integration challenges, especially with the need to maintain extremely low temperatures as qubit numbers increase.

How pregnancy transforms the brain to prepare it for parenthood

In 2008, neuroscientist Susana Carmona and colleagues found a research gap on pregnancy's effects on the human brain. Over eight years, they used MRI to study women before and after pregnancy, discovering a 2% reduction in cerebral cortex size post-pregnancy, which correlated with stronger maternal attachment, suggesting pregnancy prepares the brain for parenthood.

Red Meat Tied to Increased Dementia Risk

Higher intake of processed red meat, such as bacon and sausages, is linked to a higher dementia risk. Consuming 0.25 or more servings daily, about two servings weekly, increases dementia risk by 15% compared to consuming less than 0.10 servings daily. The study also found worse cognition associated with higher red meat consumption.

Targeting 14 modifiable risk factors from childhood to old age could prevent or delay dementia

The third Lancet Commission report suggests that addressing 14 modifiable risk factors from childhood could prevent or delay nearly half of dementia cases. New factors include high LDL cholesterol and untreated vision loss, adding to 12 previously identified risks like low education and high blood pressure.

Hubble spots a stunning spiral galaxy shining in the 'Little Lion' (image)

The Hubble Space Telescope recently captured a detailed image of the NGC 3430 spiral galaxy, 100 million light-years away in Leo Minor. The image shows swirling gas and dust, with bright blue regions indicating new star formation and orange specks of distant background galaxies. Nearby galaxies, including one influencing star formation in NGC 3430, are also present but outside the frame.

2024 Software of the Year Co-Winner – Orbital Debris Engineering Model (ORDEM)

NASA's ORDEM is an advanced orbital debris model that uses extensive data to analyze debris across various orbits. It helps satellite designers assess debris impact risks, optimize shielding, and extend mission lifespans. ORDEM also supports debris observation simulations and is crucial for spacecraft protection and mission safety as space becomes increasingly crowded.
