An artificial cell on a chip
Researchers at the University of Basel have developed a precisely controllable system for mimicking biochemical reaction cascades in cells. Using microfluidic technology, they produce miniature polymeric reaction containers equipped with the desired properties. This 'cell on a chip' is useful not only for studying processes in cells, but also for the development of new synthetic pathways for chemical applications or for biological active substances in medicine.

Black hole 'family portrait' is most detailed to date
An international research collaboration including Northwestern University astronomers has produced the most detailed family portrait of black holes to date, offering new clues as to how black holes form. An intense analysis of the most recent gravitational-wave data available led to the rich portrait as well as multiple tests of Einstein's theory of general relativity. (The theory passed each test.) The observations could be a key piece in solving the many mysteries of exactly how binary stars interact.

Astronomers discover activity on distant planetary object
A team of astronomers, led by doctoral student Colin Chandler in Northern Arizona University's Astronomy and Planetary Science PhD program, earlier this year announced their discovery of activity emanating from Centaur 2014 OG392, a planetary object first found in 2014. They published their findings in The Astrophysical Journal Letters. As a result of the team's discovery, the Centaur has recently been reclassified as a comet, and will be known as 'C/2014 OG392 (PANSTARRS).'

Topology gets magnetic: The new wave of topological magnetic materials
The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a 'topological periodic table.' However, such a classification for magnetic materials has so far been elusive, and hence very few magnetic topological materials have been discovered to date. In a new study published in the journal Nature, an international team of researchers has performed the first high-throughput search for magnetic topological materials, finding over 100 new magnetic topological insulators and semimetals.

Genetic analysis system yields new insights into bacterial pneumonia
A team of infectious disease researchers has developed a new method to identify virulence genes in Streptococcus pneumoniae, the leading cause of bacterial pneumonia. Using this technique in a mouse model of pneumonia, they were able to gain new insights into the progression of the disease and its interaction with the flu virus.

Astronomers are bulging with data
For the first time, over 250 million stars in our galaxy's bulge have been surveyed in near-ultraviolet, optical, and near-infrared light, opening the door for astronomers to reexamine key questions about the Milky Way's formation and history. Using ultraviolet data, and with 450,000 individual images, the team was able to measure the chemical composition of tens of thousands of stars spanning a large area of the bulge. The vast dataset can be explored in spectacular detail in this image.

Study: Most migratory birds rely on a greening world
A new study from the Cornell Lab of Ornithology confirms that most birds -- but not all -- synchronize their migratory movements with seasonal changes in vegetation greenness. This is the first study of its kind to cover the Western Hemisphere during the year-long life cycle of North American migratory birds that feed on vegetation, seeds, nectar, insects, or meat.

Researchers discover proton regulator of essential cancer microRNA
These findings, published in the journal Nature Chemical Biology, unveil that a 'hidden' layer of regulation by which the intrinsic dynamic ensemble of miRNA processing intermediates can direct the outcome of important biological processes in response to environmental and cellular stimuli in the absence of protein factors. If these processes go awry, then disease could result. Understanding the roles of miRNAs in disease is a needed step in finding new routes to better therapeutics.

UM researcher proposes sea-level rise global observing system
University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researcher Shane Elipot proposes a new approach to monitoring global sea-level rise. Using the existing NOAA Global Drifter Program array of roughly 1,200 buoys that drift freely with ocean currents, Elipot suggests adding additional instruments to record their height, or the "level of the sea" they ride on, to collect long-term data on the average sea levels across the world's oceans.

Bridges with limb-inspired architecture can withstand earthquakes, cut repair costs
Structural damage to any of the nation's ailing bridges can come with a hefty price of billions of dollars in repairs. New bridge designs promise more damage-resistant structures and, consequently, lower restoration costs. But if these designs haven't been implemented in the real world, predicting how they can be damaged and what repair strategies should be implemented remain unresolved.

COVID-19 containment shaped by strength, duration of natural, vaccine-induced immunity
New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19. In particular, a vaccine capable of eliciting a strong immune response could substantially reduce the future burden of infection, according to a study recently published in the journal Science.
