Published Robots and Rights: Confucianism Offers Alternative
(via sciencedaily.com) Original source As robots assume more roles in the world, a new analysis reviewed research on robot rights, concluding that granting rights to robots is a bad idea. Instead, the article looks to Confucianism to offer an alternative.
Published Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'
(via sciencedaily.com) Original source A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
Published Making the structure of 'fire ice' with nanoparticles
(via sciencedaily.com) Original source Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations.
Published Researchers successfully induce primate oocytes in the lab
(via sciencedaily.com) Original source The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.
Published The fast and the fibrous: Developing the muscles you need for speed
(via sciencedaily.com) Original source Researchers have identified the role of the large Maf transcription factor family in regulating fast twitch muscle fibers. A mouse model lacking Maf expression in the skeletal muscles exhibited a significant loss of type IIb myofibers, a subtype of fast twitch fibers. Overexpression of large Mafs promoted type IIb muscle fiber induction. The large Maf family may represent potential targets for developing treatments for muscular disorders involving fast twitch fibers.
Published Helium nuclei research advances our understanding of cosmic ray origin and propagation
(via sciencedaily.com) Original source The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles.
Published Weevils, long-nosed beetles, are unsung heroes of pollination
(via sciencedaily.com) Original source Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.
Published The metaverse can lead to better science
(via sciencedaily.com) Original source One researcher says we should look beyond the hype to see how virtual reality can make scientists more effective. But to realize the benefits, researchers must also plan well and avoid potential pitfalls.
Published Iron-rich rocks unlock new insights into Earth's planetary history
(via sciencedaily.com) Original source A new study suggests iron-rich ancient sediments may have helped cause some of the largest volcanic events in the planet's history.
Published Scientists propose revolution in complex systems modelling with quantum technologies
(via sciencedaily.com) Original source Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly re-duced memory.
Published How tasty is the food?
(via sciencedaily.com) Original source A hormone and specialized brain cells regulate feeding behavior in mice.
Published Engineers harvest abundant clean energy from thin air, 24/7
(via sciencedaily.com) Original source A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.
Published Medical 'microrobots' could one day treat bladder disease, other human illnesses
(via sciencedaily.com) Original source Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of Americans.
Published Quantum matter breakthrough: Tuning density waves
(via sciencedaily.com) Original source Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
Published Where do our limbs come from?
(via sciencedaily.com) Original source Scientists have uncovered new clues about the origin of paired appendages -- a major evolutionary step that remains unresolved and highly debated.
Published Move over, armadillos: There's a new bone-plated mammal in town
(via sciencedaily.com) Original source Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.
Published A look into the heart of cellular waste disposal
(via sciencedaily.com) Original source Researchers reveal how a nanomachine takes care of cleaning up inside the cell.
Published Engineers create bacteria that can synthesize an unnatural amino acid
(via sciencedaily.com) Original source Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The researchers also taught a single bacterial strain to create the amino acid and place it at specific sites within target proteins. These findings provide a foundation for developing unique vaccines and immunotherapies in the future.
Published Researchers find new mechanism for sodium salt detoxification in plants
(via sciencedaily.com) Original source A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
Published Researchers build bee robot that can twist
(via sciencedaily.com) Original source A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
