Published Researchers develop manual for engineering spin dynamics in nanomagnets
(via sciencedaily.com) Original source An international team of researchers has developed a comprehensive manual for engineering spin dynamics in nanomagnets -- an important step toward advancing spintronic and quantum-information technologies.
Published Happy worms have healthy eggs
(via sciencedaily.com) Original source Researchers have exposed roundworms (a well-established model organism in biological research) to selective serotonin reuptake inhibitors (SSRIs), a class of drugs used for treating depression and anxiety. Surprisingly, this treatment improved the quality of aging females' egg cells.
Published Scientists discover the dynamics of an 'extra' chromosome in fruit flies
(via sciencedaily.com) Original source Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.
Published QuanÂtum comÂputer in reverse gear
(via sciencedaily.com) Original source Large numbers can only be factorized with a great deal of computational effort. Physicists are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
Published A novel stem cell adhesive using mussels
(via sciencedaily.com) Original source A team of researchers develops stem cell adhesive for arthritis treatment using mussel adhesion protein and hyaluronic acid.
Published Scientists present evidence for a billion-years arms race between viruses and their hosts
(via sciencedaily.com) Original source Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.
Published Quantum entanglement of photons doubles microscope resolution
(via sciencedaily.com) Original source Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Do people and monkeys see colors the same way?
(via sciencedaily.com) Original source New findings in color vision research imply that humans can perceive a greater range of blue tones than monkeys do. Distinct connections found in the human retina may indicate recent evolutionary adaptations for sending enhanced color vision signals from the eye to the brain.
Published Scientists slow aging by engineering longevity in cells
(via sciencedaily.com) Original source Researchers have developed a biosynthetic 'clock' that keeps cells from reaching normal levels of deterioration related to aging. They engineered a gene oscillator that switches between the two normal paths of aging, slowing cell degeneration and setting a record for life extension.
Published Information 'deleted' from the human genome may be what made us human
(via sciencedaily.com) Original source What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome.
Published Mammalian evolution provides hints for understanding the origins of human disease
(via sciencedaily.com) Original source Even though it is important to know where these variations are located in the genome, it's also useful to know how or why these genetic variations happened in the first place.
Published Tunneling electrons
(via sciencedaily.com) Original source By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings could lead to new quantum-mechanical insights and enable electronic circuits that are a million times faster than today.
Published Brain circuits for locomotion evolved long before appendages and skeletons
(via sciencedaily.com) Original source Scientists found parallels between the neural circuitry that guides locomotion in sea slugs and in more complex animals like mammals.
Published Scientists demonstrate unprecedented sensitivity in measuring time delay between two photons
(via sciencedaily.com) Original source A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range of applications, including more feasible imaging of nanostructures, including biological samples, and nanomaterial surfaces, as well as quantum enhanced estimation based on frequency-resolved boson sampling in optical networks.
Published Researchers reveal an ancient mechanism for wound repair
(via sciencedaily.com) Original source The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens.
Published Scientists have full state of a quantum liquid down cold
(via sciencedaily.com) Original source A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing.
Published Algae in Swedish lakes provide insights to how complex life on Earth developed
(via sciencedaily.com) Original source By studying green algae in Swedish lakes, a research team has succeeded in identifying which environmental conditions promote multicellularity. The results give us new clues to the amazing paths of evolution.
Published Putting hydrogen on solid ground: Simulations with a machine learning model predict a new phase of solid hydrogen
(via sciencedaily.com) Original source Hydrogen, the most abundant element in the universe, is found everywhere from the dust filling most of outer space to the cores of stars to many substances here on Earth. This would be reason enough to study hydrogen, but its individual atoms are also the simplest of any element with just one proton and one electron.
Published Fungal genetics could help develop novel biotechnologies
(via sciencedaily.com) Original source An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
Published Engineering the next generation of cell and gene therapies
(via sciencedaily.com) Original source Investigators are developing a novel way to treat amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa using engineered stem cells that may eventually lead to personalized treatments.
