Published Can consciousness exist in a computer simulation?
(via sciencedaily.com) Original source A new essay explores which conditions must be met for consciousness to exist. At least one of them can't be found in a computer.
Published Hundreds of new genome sequences fill gaps in the fruit fly tree of life
(via sciencedaily.com) Original source A multitude of new genomic sequence data fills major gaps in the fruit fly tree of life, researchers report.
Published Another intermediate-mass black hole discovered at the center of our galaxy
(via sciencedaily.com) Original source So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.
Published Using AI to scrutinize, validate theories on animal evolution
(via sciencedaily.com) Original source By harnessing the power of machine learning, researchers have constructed a framework for analyzing what factors most significantly contribute to a species' genetic diversity.
Published Secrets behind viral precision
(via sciencedaily.com) Original source New research is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena.
Published The courtship of leopard seals off the coast of South America
(via sciencedaily.com) Original source A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.
Published Singing the science: Using karaoke to examine blushing
(via sciencedaily.com) Original source A new collaboration explores the neural substrates of blushing in a MRI scanner.
Published Ant insights lead to robot navigation breakthrough
(via sciencedaily.com) Original source Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.
Published The most endangered fish are the least studied
(via sciencedaily.com) Original source The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).
Published Want to spot a deepfake? Look for the stars in their eyes
(via sciencedaily.com) Original source In an era when the creation of artificial intelligence (AI) images is at the fingertips of the masses, the ability to detect fake pictures -- particularly deepfakes of people -- is becoming increasingly important. So what if you could tell just by looking into someone's eyes? That's the compelling finding of new research which suggests that AI-generated fakes can be spotted by analyzing human eyes in the same way that astronomers study pictures of galaxies.
Published Completely stretchy lithium-ion battery for flexible electronics
(via sciencedaily.com) Original source When you think of a battery, you probably don't think stretchy. But batteries will need this shape-shifting quality to be incorporated into flexible electronics, which are gaining traction for wearable health monitors. Now, researchers report a lithium-ion battery with entirely stretchable components, including an electrolyte layer that can expand by 5000%, and it retains its charge storage capacity after nearly 70 charge/discharge cycles.
Published What fat cats on a diet may tell us about obesity in humans
(via sciencedaily.com) Original source Pet cats may be excellent animal models for the study of obesity origins and treatment in humans, a new study of feline gut microbes suggests -- and both species would likely get healthier in the research process, scientists say.
Published Smart soil can water and feed itself
(via sciencedaily.com) Original source A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.
Published Cuttlefish can form false memories, too
(via sciencedaily.com) Original source During an event, details like what you saw, smelled, and felt aren't stored as a single memory. Rather, they are encoded and stored in your brain separately. To retrieve that memory, those pieces must get put back together. When that doesn't happen in the right way or details are distorted, it can lead to the creation of false memories. Now researchers have evidence that the common cuttlefish may create false memories, too.
Published Astronomers spot a 'highly eccentric' planet on its way to becoming a hot Jupiter
(via sciencedaily.com) Original source The newly discovered planet TIC 241249530 b has the most highly elliptical, or eccentric, orbit of any known planet. It appears to be a juvenile planet that is in the midst of becoming a hot Jupiter, and its orbit is providing some answers to how such large, scorching planets evolve.
Published Psilocybin generates psychedelic experience by disrupting brain network
(via sciencedaily.com) Original source Researchers report that psilocybin, the active ingredient in magic mushrooms, destabilizes a critical network of brain areas involved in introspective thinking. The findings provide a neurobiological explanation for the drug's mind-bending effects.
Published Logged forests can still have ecological value -- if not pushed too far
(via sciencedaily.com) Original source Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
Published Influenza viruses can use two ways to infect cells
(via sciencedaily.com) Original source Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species -- and potentially jump between animals and humans.
Published Enzyme-powered 'snot bots' help deliver drugs in sticky situations
(via sciencedaily.com) Original source Snot might not be the first place you'd expect nanobots to be swimming around. But this slimy secretion exists in more places than just your nose and piles of dirty tissues -- it also lines and helps protect the lungs, stomach, intestines and eyes. And now, researchers have demonstrated in mice that their tiny, enzyme-powered 'snot bots' can push through the defensive, sticky layer and potentially deliver drugs more efficiently.
Published Could intensive farming raise risk of new pandemics?
(via sciencedaily.com) Original source Industrialized farming is often thought to reduce the risk of zoonotic diseases because of better control, biosecurity and separation of livestock. A new study examines the effect of social and economic factors -- which are often overlooked in traditional assessments.
