Published Where quantum computers can score
(via sciencedaily.com) Original source The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.
Published How cells are ahead of the curve
(via sciencedaily.com) Original source The curvature of a surface determines the migration behavior of biological cells. They preferentially move along valleys or grooves while avoiding ridges. These findings gave rise to a model predicting cellular behavior. Such universal principles now allow a better understanding of the migration of immune and cancer cells, paving the way for new treatment options.
Published An innovative mixed light field technique for immersive projection mapping
(via sciencedaily.com) Original source A novel mixed light field technique that utilizes a mix of ray-controlled ambient lighting with projection mapping (PM) to obtain PM in bright surroundings has been developed by scientists. This innovative technology utilizes a novel kaleidoscope array to achieve ray-controlled lighting and a binary search algorithm for removing ambient lighting from PM targets. It provides an immersive augmented reality experience with applications in various fields.
Published Engineers measure pH in cell condensates
(via sciencedaily.com) Original source In a first for the condensate field, researchers have figured out how nucleolar sub-structures are assembled. This organization gives rise to unique pH profiles within nucleoli, which they measured and compared with the pH of nearby non-nucleolar condensates including nuclear speckles and Cajal bodies.
Published Machine learning classifier accelerates the development of cellular immunotherapies
(via sciencedaily.com) Original source Making a personalized T cell therapy for cancer patients currently takes at least six months. Scientists have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.
Published New study shows analog computing can solve complex equations and use far less energy
(via sciencedaily.com) Original source A team of engineers has proven that their analog computing device, called a memristor, can complete complex, scientific computing tasks while bypassing the limitations of digital computing.
Published Information overload is a personal and societal danger
(via sciencedaily.com) Original source We are all aware of the dangers of pollution to our air, water, and earth. In a recently published letter, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload.
Published Small amounts of licorice raise blood pressure, study finds
(via sciencedaily.com) Original source It is known that large amounts of licorice cause high blood pressure. A new study now shows that even small amounts of licorice raise blood pressure. The individuals who react most strongly also show signs of strain on the heart.
Published Alzheimer's drug fermented with help from AI and bacteria moves closer to reality
(via sciencedaily.com) Original source Researchers combined artificial intelligence and chemical biosensors to ferment the precursor of an Alzheimer's drug in bacteria.
Published New bioengineered protein design shows promise in fighting COVID-19
(via sciencedaily.com) Original source A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.
Published Sleep-wake rhythm: Fish change our understanding of sleep regulation
(via sciencedaily.com) Original source Researchers have discovered that some fish -- unlike humans -- do not need orexin to stay awake. This molecule was thought to be necessary for normal wake and sleep rhythms in vertebrates. Humans without orexin suffer from narcolepsy.
Published New discovery reveals how the egg controls sperm entry
(via sciencedaily.com) Original source After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods.
Published Even cells know the importance of recycling
(via sciencedaily.com) Original source Researchers uncovered the mechanistic details behind how several proteins interact to help cells recognize and remove damaged mitochondria. Optineurin (OPTN) and its interactions are needed to provide a contact site for another protein, Tank-binding kinase 1 (TBK1), during this process. The OPTN-TBK1 relationship is necessary for these mitochondria to be recognized and eliminated from the cell. This mechanism may have relevance for developing drugs to treat Parkinson's disease.
Published Sulfur and the origin of life
(via sciencedaily.com) Original source A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.
Published Tryptophan in diet, gut bacteria protect against E. coli infection
(via sciencedaily.com) Original source Gut bacteria and a diet rich in the amino acid tryptophan can play a protective role against pathogenic E. coli, which can cause severe stomach upset, cramps, fever, intestinal bleeding and renal failure.
Published New AI technology enables 3D capture and editing of real-life objects
(via sciencedaily.com) Original source Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.
Published Artificial intelligence detects heart defects in newborns
(via sciencedaily.com) Original source Researchers have developed an algorithm that provides an automatic and reliable method of detecting a certain heart defect in newborns.
Published New computational strategy boosts the ability of drug designers to target proteins inside the membrane
(via sciencedaily.com) Original source Hitting targets embedded within the cell membrane has long been difficult for drug developers due to the membrane's challenging biochemical properties. Now, chemists have demonstrated new custom-designed proteins that can efficiently reach these 'intramembrane' targets.
Published Straightening teeth? AI can help
(via sciencedaily.com) Original source A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.
Published Staying in the loop: How superconductors are helping computers 'remember'
(via sciencedaily.com) Original source To advance neuromorphic computing, some researchers are looking at analog improvements -- advancing not just software, but hardware too. Research shows a promising new way to store and transmit information using disordered superconducting loops.
