A novel embedded kernel CNN-PCFF algorithm for breast cancer pathological image classification

Early detection of breast cancer using CNNs can improve survival rates, but high-dimensional features can lead to complexity and overfitting. The CNN-PCFF algorithm addresses this by using multi-kernel principal component analysis for dimensionality reduction, enhancing classification performance and making it effective for analyzing breast cancer pathology images.

Elon Musk unveils the Robovan: the biggest surprise from Tesla’s We, Robot event

Elon Musk revealed Tesla’s Robovan, an electric, autonomous vehicle designed to transport up to 20 people or goods in high-density areas, at the We, Robot event in Los Angeles. While Musk shared few details on cost, production, or release, the prototype was showcased as a sleek and futuristic model.

AstraZeneca synthetic chemistry prize winner celebrates ‘culmination of a high-quality academia-industry collaboration’

Ruth Webster of the University of Cambridge won the 2024 AstraZeneca prize in synthetic chemistry for her innovative work in iron catalysis. Her research uses simple, inexpensive ligands to create sustainable and efficient catalytic systems, achieving low catalyst loadings. This approach, demonstrated through collaboration with AstraZeneca, proves valuable for both discovery and development chemists, exemplifying modern synthetic chemistry's holistic needs.

Inspired by Spider-Man, researchers recreate web-slinging technology

Tufts University researchers have developed a web-slinging technology inspired by Spider-Man, using silk fibroin from moth cocoons. This innovative material can be shot as a liquid, instantly solidify into a string, and adhere to objects. The technology, created at the Silklab, mimics natural silk production by various insects. It builds on previous silk-based innovations, including underwater glues, printable sensors, and food preservation coatings. This breakthrough, published in Advanced Functional Materials, demonstrates the potential of biomimetic materials in creating novel engineering solutions.

MRI-linac keeps track of brain tumour changes during radiotherapy

University of Miami researchers found that daily MRI scans during radiotherapy for glioblastoma patients can detect tumor changes earlier than standard methods. This approach, using MRI-guided radiotherapy, could allow for quicker treatment adjustments and potentially improve outcomes for patients with this aggressive brain cancer.

Pulsed Dye Laser an Option for Acne Treatment

Dr. Arielle Kauvar highlighted the benefits of using lasers and energy-based treatments for moderate to severe acne at a recent symposium. She noted that these methods can be more effective than traditional topical or antibiotic treatments and may also address associated hyperpigmentation and scarring. Kauvar emphasized the multifactorial nature of acne, suggesting that inflammation and immune activation might be primary factors in its development. She mentioned two FDA-cleared 1726-nm lasers, AviClear and Accure Acne Laser System, which target sebaceous glands, though their availability is currently limited.

New research explores hydrogen sulfide as treatment for obesity

Dr. Arielle Kauvar discussed the benefits of lasers and energy-based treatments for moderate to severe acne at a symposium, noting their effectiveness over traditional methods and ability to treat hyperpigmentation and scarring. She highlighted acne's multifactorial nature, with inflammation and immune activation as possible primary factors. Kauvar mentioned two FDA-cleared 1726-nm lasers, AviClear and Accure, that target sebaceous glands, though they're not widely available yet.

Secretive Space Force Vehicle Will Conduct ‘Groundbreaking’ Maneuver to Adjust Its Orbit

After over 10 months in space, the U.S. Space Force’s X-37B spaceplane will use Earth’s atmospheric drag to change its orbit for the first time. Launched by SpaceX’s Falcon Heavy in December 2023, this marks the X-37B’s seventh mission. The spaceplane will perform aerobraking maneuvers to adjust its orbit with minimal fuel use. Before concluding the mission, it will dispose of its service module, though further objectives remain undisclosed. This approach highlights the Space Force’s focus on innovation in space-based national security missions, according to Air Force Secretary Frank Kendall.

Gaia space telescope discovers 55 'runaway' careening away from stellar cluster at 80 times the speed of sound

Using Europe’s Gaia space telescope, astronomers have discovered 55 runaway stars ejected at high speeds from the young star cluster R136 in the Large Magellanic Cloud. This is the largest number of stars observed escaping from a single cluster. Located about 158,000 light-years away, R136 hosts hundreds of thousands of stars, some up to 300 times the mass of the sun. The runaway stars were ejected in two bursts over the past two million years, with speeds exceeding 62,000 mph. This discovery, led by researcher Mitchel Stoop from the University of Amsterdam, increases the known number of runaway stars tenfold and reveals multiple major escape events in R136 due to gravitational disruptions among crowded stars.
