Wavelength-selective thermal emitters (WS-TEs) have been frequently designed to achieve desired target emissivity spectra, as in typical emissivity engineering, for broad applications such as thermal camouflage, radiative cooling, and gas sensing, etc.

However, previous designs required prior knowledge of materials or structures for different applications, and the designed WS-TEs usually vary from application to application in terms of materials and structures, thus there is no general design framework for emissivity engineering across different applications. Moreover, previous designs fail to tackle the simultaneous design of both materials and structures, as they either fix materials to design structures or fix structures to select suitable materials.

In a new paper published in Light: Science & Applications, a team of scientists, led by Professor Run Hu from School of Energy and Power Engineering, Huazhong University of Science and Technology, China, and coworkers have proposed a general deep learning framework based on the deep Q-learning network algorithm (DQN) for efficient optimal design of WS-TEs across different applications.

Histopathology describes the process of examining pieces of tissue using a microscope. Light microscopic (LM) examination of tissue helps diagnose several types of cancer by allowing pathologists to view cellular changes within a biopsy sample.

The workload of pathologists has increased in recent years due to policies that encourage screening for early cancer diagnoses. In addition, longer life expectancies and scientific advances have led to an increased number of cancer survivors, further increasing the need for pathology evaluations. Thus, strategies to efficiently utilize the limited pathology resources have become essential to maintaining standards of care and the health and safety of patients.

Digital pathology (DP) has emerged as an alternative method for analyzing tissue samples by stitching together digital images from histopathology slides. Automated slide scanners can rapidly generate these high-resolution images with minimal human interaction. In addition to the speed, DP does not require a microscope, offering remote viewing possibilities. Pathologists and other healthcare professionals can easily share images.

This is a sci-fi documentary, looking at how warp drive technology and warp spaceships work. As well as the negative energy needed to travel at warp speed. The faster than light journey to Mars takes 18.6 seconds, but how long does it take to reach the nearest black hole?

It is a journey showing the future science of space travel, exploration, and future space technology.

The SpaceX Dragon spacecraft undocked from the space-facing port of the International Space Station’s Harmony module at 9:20 a.m. EST over the Pacific Ocean, west of Ecuador, to complete the third all-private astronaut mission to the orbiting laboratory, Axiom Mission 3 (Ax-3).

Dragon is slowly maneuvering away from the orbital laboratory into an orbital track that will return the astronaut crew and its cargo safely to Earth, targeting a splashdown off the coast of Daytona, Florida, at approximately 8:30 a.m. EST Friday, Feb. 9.

Ax-3 astronauts Michael López-Alegría, Walter Villadei, Marcus Wandt, and Alper Gezeravci will complete 18 days aboard the orbiting laboratory at the conclusion of their mission. The SpaceX Dragon will return to Earth with more than 550 pounds of science and supplies, including NASA experiments and hardware.

The ability to distinguish between left-and right-handed molecules using mass spectrometry could streamline a laborious part of drug discovery.

A fledgling startup founded by one of OpenAI’s first engineering hires is looking to “redefine manufacturing,” with AI-powered factories for creating bespoke precision parts.

Daedalus, as the company is called, is based in the southwestern German city of Karlsruhe, where its solo factory is currently housed. Here, Daedalus takes orders from industries such as medical devices, aerospace, defense, and semiconductors, each requiring unique components for their products. For example, a pharmaceutical company might require a customized metal casing for a valve used in the production of a particular medicine.

As it looks to ramp up operations with a view toward opening additional factories in its domestic market, Daedalus today announced it has raised $21 million in a Series A round of funding led by Nokia-funded NGP Capital, with participation from existing investors Khosla Ventures and Addition.

Summary: A new study illuminated how fruit flies navigate by revealing the communication between their internal compass and steering brain regions. This study shows that three distinct neuron groups translate directional signals into corrective actions, allowing fruit flies to adjust their course effectively.

These findings not only deepen our understanding of navigation in simpler organisms but also lay the groundwork for future research into the neural basis of behavior in more complex species, including humans.

By exploring the intricacies of fruit fly brains, scientists have uncovered fundamental principles of cognitive processing and behavior adjustment, offering insights into how internal cognitive states like direction sense are converted into tangible actions.
