A new way to create realistic 3D shapes using generative AI

MIT researchers have improved the process of generating 3D models using generative AI. By addressing issues in Score Distillation, a method that uses 2D image models for 3D creation, they developed a simpler fix that produces sharper, more realistic 3D shapes without expensive retraining or postprocessing. Their work enhances mathematical understanding of 3D generation techniques and aims to streamline design workflows, enabling creators to craft high-quality 3D shapes more efficiently. The findings will be presented at the Neural Information Processing Systems conference.

Exploring vision transformers and XGBoost as deep learning ensembles for transforming carcinoma recognition

A new method enhances early detection of colorectal cancer (CRC) using deep learning ensembles with CADx. By refining the dataset and combining CNNs (e.g., ADaDR-22) with Vision Transformers and XGBoost, researchers improved accuracy and feature extraction. Dataset augmentation using DCGAN increased diversity. The Vision Transformer model achieved 93.4% accuracy and 98.8% AUC, outperforming the XGBoost model (92.2% accuracy, 97.8% AUC). This approach demonstrates the importance of balanced datasets and advanced AI for precise medical imaging and early CRC diagnosis.

Chemical structure's carbon capture ability doubled by new research

Oregon State University researchers improved carbon capture efficiency in a copper-based MOF by exposing it to ammonia gas, doubling its CO2 absorption. This method forms stable copper-carbamate compounds and allows energy-efficient regeneration with water. The approach enhances MOF selectivity for CO2, offering a reusable and cost-effective alternative to traditional sorbents.

Nuclear shape transitions visualized for the first time

Simulations at CERN's LHC reveal that xenon-129 nuclei change shape during ultra-relativistic collisions, transitioning from oval to spherical. This discovery sheds light on nuclear phase transitions and quark-gluon plasma behavior under extreme conditions, advancing nuclear physics and quantum chromodynamics.

Scientists reveal 'neural tourniquet' that can stop bleeding with nerve stimulation

Research suggests vagus nerve stimulation can reduce bleeding by promoting blood clotting, a potential "neural tourniquet" mechanism. Experiments in animals and humans show the technique activates immune cells and platelets, enhancing clotting ability. If confirmed in clinical trials, this approach could be used before surgeries to prevent excessive bleeding, addressing an unmet medical need. Challenges include proving consistent efficacy and reducing bleeding in real-world scenarios. Vagus nerve stimulation is already used for epilepsy and depression, suggesting minimal side effects.

BCG Vaccine May Protect Against Long COVID Symptoms

A phase 3 trial found that administering the BCG vaccine during mild-to-moderate COVID-19 reduced long-COVID symptoms at 6 and 12 months. Benefits included fewer issues with sleep, memory, and concentration, along with lower overall long-COVID scores. A paradoxical effect on hair loss was noted, with reductions in men but slight increases in women. Male sex was the strongest predictor of long COVID. While promising, limitations include loss to follow-up and lack of testing for prior mycobacterial exposure. Findings suggest BCG may be more effective as a treatment than a preventive measure.

Disrupted sleep-wake rhythms linked to liver disease progression

The prevalence of MASLD (formerly NAFLD) is rising globally, affecting 30% of adults and predicted to surpass 55% by 2040 due to obesity and sedentary lifestyles. MASLD increases risks for diabetes, cancers, and cardiovascular issues. Using 24/7 actigraphy, a study found patients with MASLD experience fragmented sleep, waking 55% more often at night and spending more time awake after sleeping. They also reported poor sleep linked to psychological stress. Sleep disturbances were similar across MASLD, MASH, and cirrhosis cases, highlighting the condition's broader health implications.

James Webb Space Telescope smashes its own record to find the earliest galaxies that ever existed

The James Webb Space Telescope (JWST) has identified five potential galaxies dating back 13.6 billion years, likely among the first to form after the Big Bang. Using gravitational lensing to amplify faint light, JWST pushed its limits to detect these ancient galaxies. If confirmed, they would predate the current earliest known galaxy by 90 million years. These findings could reshape understanding of early galaxy formation, possibly involving rapid star growth influenced by black holes, supernova feedback, or dark energy. Further studies will confirm these candidates.

SpaceX Falcon 9 rocket launching on record-breaking 24th flight early Dec. 4

SpaceX is set to break its rocket reuse record on December 4th with a Falcon 9 launch from Cape Canaveral, carrying 24 Starlink satellites. This will be the first stage booster's 24th flight, surpassing the previous record of 23 flights. The booster is expected to land on a drone ship in the Atlantic Ocean while the upper stage deploys the satellites about 65 minutes after launch.
