Boundary guidance network for medical image segmentation

Accurate segmentation of bladder tumors is vital for treatment and prognosis. While cystoscopy is the diagnostic gold standard, most current segmentation work uses deep learning on CT and MRI. This paper introduces the boundary guidance network, which combines CNNs and Parallel ViT to capture tumor features and guide decoding with boundary information. Tested on a new cystoscopic bladder tumor dataset (BTD), the network achieved high accuracy and outperformed state-of-the-art methods on BTD and other datasets.

Floating No More: Object-Ground Reconstruction from a Single Image

Recent advancements in 3D object reconstruction often fail to capture the relationship between objects, ground, and camera, affecting image editing. The ORG task addresses this by reconstructing object geometry with the ground surface. Experiments show ORG improves shadow generation and pose manipulation compared to traditional methods.

Twisted carbon nanotubes could achieve significantly better energy storage than advanced lithium-ion batteries

An international team, including UMBC researchers, has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. This discovery, published in Nature Nanotechnology, could benefit lightweight and compact devices like medical implants and sensors. Sanjeev Kumar Ujjain and Preety Ahuja from UMBC's Center for Advanced Sensor Technology contributed significantly to the research.

X(3960) is a tetraquark, theoretical analysis suggests

A theoretical study has confirmed that a particle observed at CERN’s LHCb experiment in 2022 is indeed a tetraquark, which supports earlier hypotheses. Tetraquarks, consisting of four quarks, offer new insights into the strong interactions that bind quarks in hadrons. Bing-Dong Wan of Liaoning Normal University and Hangzhou Institute for Advanced Study notes that while many new hadrons have been discovered since 2003, only a few have been confirmed as tetraquarks.

With ‘Digital Twins,’ The Doctor Will See You Now

Manda Randles is developing "digital twins," personalized medical simulations to aid in disease diagnosis and treatment. With a background in coding and biology, she created a blood flow model named Harvey at Harvard and now leads a lab at Duke. Her innovative work earned her the Association for Computing Machinery Prize in Computing.

Here’s the Latest List of Lead-Tainted Cinnamon Products

The FDA has expanded its list of lead-tainted cinnamon products, now including ground cinnamon from El Servidor. Since October 2023, warnings have been issued for 10 contaminated products under various brands like El Servidor, La Fiesta, Marcum, MK, Swad, Supreme Tradition, El Chilar, WanaBana, Weis, and Schnucks. Consumers are advised to discard and avoid these products due to the serious health risks of lead exposure.

Seventh patient ‘cured’ of HIV: why scientists are excited

A 60-year-old man in Germany is the seventh person to be declared HIV-free after receiving stem cells with one copy of the CCR5 gene mutation. This challenges the belief that complete CCR5 resistance is necessary for an HIV cure.

SpaceX roars back to orbit barely two weeks after in-flight anomaly

On Saturday at 1:45 am local time, SpaceX's Falcon 9 rocket successfully launched 23 Starlink satellites from Kennedy Space Center. This mission marked the rocket's return-to-flight after a previous failure. The booster completed its 17th flight and landed on a drone ship, while the second stage deployed the satellites into orbit.

Hubble Images a Classic Spiral 

NASA/ESA’s Hubble Space Telescope captured a detailed image of the spiral galaxy NGC 3430, located 100 million light-years away in Leo Minor. The galaxy, which has a bright core and well-defined spiral arms, shows star formation driven by nearby galaxies. NGC 3430's structure was pivotal in Edwin Hubble’s 1926 galaxy classification, contributing to the modern understanding of galaxy types.
