A new recycling process for silicones could greatly reduce the sector's environmental impacts

Matter and energy from Science Daily Feed - Thu, 04/24/2025 - 1:54pm
A study describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector's environmental impacts. This is the first universal recycling process that brings any type of used silicone material back to an earlier state in its life cycle where each molecule has only one silicon atom. And there is no need for the raw materials currently used to design new silicones. Moreover, since it is chemical and not mechanical recycling, the reuse of the material can be carried out infinitely.

World's Largest Solar Telescope Gets the World's Largest Spectro-Polarimeter

Universe Today Feed - Thu, 04/24/2025 - 1:23pm

Telescopes can have more than one sensor. Those sensors can utilize some of the same infrastructure, like lenses and mirrors, and specialize in collecting different data. A good example of this is the Inouye Solar Telescope (IST). It is the largest solar telescope in the world, with a primary mirror diameter of 4 meters. It also has five separate instruments, four of which are currently in operation. The latest of these to come online is the Visible Tunable Filtergraph (VTF), which just collected its first light according to a press release by the Max Planck Institute for Solar Research, one of the project partners.

Half the Stellar Mass in the Universe Formed During Cosmic Noon

Universe Today Feed - Thu, 04/24/2025 - 12:28pm

About 380,000 years after the Big Bang, the first atoms formed. The first light of what we now see as the cosmic microwave background was released, and the primordial hydrogen and helium grew cold and dark. The cosmos entered a dark age for about 100 million years until the first stars and galaxies started to form. You could say the rise of galaxies marked cosmic morning. But star formation didn't really kick into gear for another 2-3 billion years, during what astronomers call cosmic noon. This period can be difficult to observe, but a new study gives us an unprecedented view of this epoch.

Vera Rubin Could Triple the Number of Known Satellite Galaxies Around the Milky Way

Universe Today Feed - Thu, 04/24/2025 - 11:10am

The Milky Way has more than 30 known satellite galaxies. The Large and Small Magellanic Clouds are the largest and most well-known; other lesser-known ones, like the Sagittarius Dwarf Galaxy, are also on the list. Astronomers think there are many more small satellites that are difficult to detect but essential in understanding the Milky Way. The Vera Rubin Observatory should help astronomers find many more of them.

Scientists use James Webb Space Telescope to better understand solar system's origins

Space and time from Science Daily Feed - Thu, 04/24/2025 - 9:17am
Using the James Webb Space Telescope (JWST), scientists analyzed far-away bodies -- known as Trans-Neptunian Objects (TNOs) -- and found varying traces of methanol. The discoveries are helping them better classify different TNOs and understand the complex chemical reactions in space that may relate to the formation of our solar system and the origin of life.

Combining signals could make for better control of prosthetics

Matter and energy from Science Daily Feed - Thu, 04/24/2025 - 9:16am
Combining two different kinds of signals could help engineers build prosthetic limbs that better reproduce natural movements, according to a new study. A combination of electromyography and force myography is more accurate at predicting hand movements than either method by itself.

Evidence blasted into space: Mystery why some meteorites look less shocked solved

Space and time from Science Daily Feed - Thu, 04/24/2025 - 9:12am
Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres.

Flying robots unlock new horizons in construction

Matter and energy from Science Daily Feed - Thu, 04/24/2025 - 9:11am
An international team has explored how in future aerial robots could process construction materials precisely in the air -- an approach with great potential for difficult-to-access locations or work at great heights. The flying robots are not intended to replace existing systems on the ground, but rather to complement them in a targeted manner for repairs or in disaster areas, for instance.

Trawling-induced sediment resuspension reduces CO2 uptake

Matter and energy from Science Daily Feed - Thu, 04/24/2025 - 9:11am
When bottom trawls are dragged across the seafloor, they stir up sediments. This not only releases previously stored organic carbon, but also intensifies the oxidation of pyrite, a mineral present in marine sediments, leading to additional emissions of carbon dioxide (CO2).

New approach makes AI adaptable for computer vision in crop breeding

Computers and Math from Science Daily Feed - Thu, 04/24/2025 - 9:10am
Scientists developed a machine-learning tool that can teach itself, with minimal external guidance, to differentiate between aerial images of flowering and nonflowering grasses -- an advance that will greatly increase the pace of agricultural field research, they say. The work was conducted using images of thousands of varieties of Miscanthus grasses, each of which has its own flowering traits and timing.

Plant-based calamari that rivals real seafood in texture

Matter and energy from Science Daily Feed - Thu, 04/24/2025 - 9:10am
Plant-based seafood alternatives should have similar flavors, textures and nutritional content to the foods they mimic. And recreating the properties of fried calamari rings, which have a neutral flavor and a firm, chewy texture after being cooked, has been a challenge. Building off previous research, a team describes successfully using plant-based ingredients to mimic calamari that matches the real seafood's characteristic softness and elasticity.

Prebiotic Molecules are Forming in Space

Universe Today Feed - Thu, 04/24/2025 - 9:03am

We associate complex chemistry with planets or other bodies, where energy and matter interact in dynamic associations. But as science advances, researchers are finding prebiotic chemistry in a wider variety of places, including in space itself. New research shows that some prebiotic chemicals, part of the recipe for life itself, can form in the cold vacuum of space.
