This could revolutionize insulin and protein-based drug treatments, enhancing ease and comfort.
MIT has developed an ingestible capsule inspired by squid propulsion, delivering drugs directly to the stomach without needles.
Caltech’s new optical devices, evolved by algorithms and crafted via precise 3D printing, offer advanced light-manipulation for applications like augmented reality and cameras.
Researchers at Caltech have developed a groundbreaking technology that “evolves” optical devices and fabricates them using a specialized 3D printer. These devices, composed of optical metamaterials, gain their unique properties from nanometer-scale structures. This innovation could enable cameras and sensors to detect and manipulate light in ways previously impossible at such small scales.
The research was conducted in the lab of Andrei Faraon, the William L. Valentine Professor of Applied Physics and Electrical Engineering and was published in the journal Nature Communications.
A new method enables researchers to analyze magnetic nanostructures with a high resolution. It was developed by researchers at Martin Luther University Halle-Wittenberg (MLU) and the Max Planck Institute of Microstructure Physics in Halle.
The new method achieves a resolution of around 70 nanometers, whereas normal light microscopes have a resolution of just 500 nanometers. This result is important for the development of new, energy-efficient storage technologies based on spin electronics. The team reports on its research in the current issue of the journal ACS Nano.
Normal optical microscopes are limited by the wavelength of light and details below around 500 nanometers cannot be resolved. The new method overcomes this limit by utilizing the anomalous Nernst effect (ANE) and a metallic nano-scale tip. ANE generates an electrical voltage in a magnetic metal that is perpendicular to the magnetization and a temperature gradient.
These robots have already proved popular in Europe and helped with extinguishing the Notre Dame fire in 2019.
Plant based fabric can help reduce exposure to oil based fabrics so there are less cancer risk with clothing. Washi is made many different ways but can be done even with paper pulp and also paper thread.
“The fabric is soft, resistant to water, and it is even washable,” said 61-year-old company president and granddaughter of the founder, Akemi Kawamura, describing the characteristics of washi jackets.
Japanese paper is cut thin and twisted into threads before being woven into fabrics with special machines. “It’s light and airy, so it’s warm in winter, but breathable and comfortable in the summer,” she said.
Some researchers and public health experts have also expressed concerns that microplastic exposure can lead to babies being born underweight.
Recent studies found that the average liter of store-bought bottled water contains more than 240,000 nanoplastics while the majority of meat and plant-based alternatives contain tiny plastics linked to cancer.
Scientists have cautioned that it will take time to transfer to creating the new material because existing manufacturing equipment was only built for traditional plastic.
The fashion world is buzzing about a new material that’s changing the game: mushroom leather. Made from mycelium, this innovative textile is taking the industry by storm, offering a sustainable and stylish alternative to traditional leather.
But it’s not just about looking good — this fungal fashion movement is about embracing a more eco-conscious and cruelty-free approach to clothing production.
What makes mushroom leather so remarkable? It all starts with mycelium, the thread-like, dense cellular structure that forms the vegetative part of a fungus.
For decades, scientists have used the Milky Way as a model for understanding how galaxies form. But three new studies raise questions about whether the Milky Way is truly representative of other galaxies in the universe.
“The Milky Way has been an incredible physics laboratory, including for the physics of galaxy formation and the physics of dark matter,” said Risa Wechsler, the Humanities and Sciences Professor and professor of physics in the School of Humanities and Sciences. “But the Milky Way is only one system and may not be typical of how other galaxies formed. That’s why it’s critical to find similar galaxies and compare them.”
To achieve that goal, Wechsler cofounded the Satellites Around Galactic Analogs (SAGA) Survey dedicated to comparing galaxies similar in mass to the Milky Way.
Using various telescopes, an international team of astronomers has conducted a comprehensive study of a double-lined spectroscopic binary known as HD 34736. The study, published November 6 in the Monthly Notices of the Royal Astronomical Society, delivers important insights into the properties of this system.
So far, the majority of binaries have been detected by Doppler shifts in their spectral lines, hence these systems are called spectroscopic binaries. Observations show that in some spectroscopic binaries, spectral lines from both stars are visible, and these lines are alternately double and single. These systems are known as double-lined spectroscopic binaries (SB2).
HD 34,736 is an SB2 system consisting of two chemically peculiar late B-type stars, located some 1,215 light years away. Previous observations of HD 34,736 have found that the system has an extraordinarily strong magnetic field exceeding 4.5 kG. The effective temperatures of the primary and secondary star were found to be 13,700 and 11,500 K, respectively.
