The physics behind tumor growth
Researchers at Duke University have developed a predictive theory for tumor growth that approaches the subject from a new point of view. Rather than focusing on the biological mechanisms of cellular growth, the researchers instead use thermodynamics and the physical space the tumor is expanding into to predict its evolution from a single cell to a complex cancerous mass.

Automakers delay recalls to minimize stock penalties, avoid being the first safety issue in news
An initial recall by one firm prompts clusters of additional recalls in close proximity by competitor firms, according to 'Hiding in the Herd: The Product Recall Clustering Phenomenon,' forthcoming in Manufacturing and Service Operations Management from Kaitlin Wowak, assistant professor of IT, analytics, and operations at Notre Dame's Mendoza College of Business.

Helium nuclei at the surface of heavy nuclei discovered
Scientists are able to selectively knockout nucleons and preformed nuclear clusters from atomic nuclei using high-energy proton beams. In an experiment the existence of preformed helium nuclei at the surface of several tin isotopes could be identified in a reaction. The results confirm a theory, which predicts the formation of helium clusters in low-density nuclear matter and at the surface of heavy nuclei. (2021-01-15)

A most distant signal
Nearly every galaxy hosts a monster at its center -- a supermassive black hole millions to billions times the size of the Sun. Some of these black holes are particularly active, whipping up stars, dust and gas into glowing accretion disks emitting powerful radiation into the cosmos as they consume matter around them. These quasars are some of the most distant objects that astronomers can see, and there is now a new record for the farthest one ever observed. (2021-01-15)

Study the boundary between bulk, nano and molecule scale of gold plasmonic physics
The collective behavior of electrons in metal plasmons reflects the important difference between condensed matter and molecule-like ones. With the help of gold clusters with precise atom numbers(N), the evolution of plasmonic response is clarified and three regimes are observed, each with distinct physics. An atomically-precise evolution picture of plasmon physics is shown with 3 regimes: classical plasmon (N=887-70000), quantum confinement corrected plasmon (N=300-887) and molecule related plasmon (N<300). (2021-01-14)

Researchers rewind the clock to calculate age and site of supernova blast
Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA's Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more accurate estimate of the location and time of the stellar detonation. (2021-01-14)

Astronomers document the rise and fall of a rarely observed stellar dance
Astronomers have catalogued 126 years of changes to HS Hydra, a rare evolving eclipsing binary star system. Analyzing observations from astro-photographic plates in the late 1800s to TESS observations in 2019, they show that the two stars in HS Hydra began to eclipse each other around a century ago, peaking in the 1960s. The degree of eclipsing then plummeted over the course of just a half century, and will cease around February 2021. (2021-01-14)

Rare star's giant gamma-ray burst GRB 204015A captured close to our home galaxy
Earth gets blasted by mild gamma ray bursts most days. But sometimes a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. It erupted from a rare, powerful neutron star called a magnetar - giving new clues to GRB origins - and from relatively nearby. The extreme explosions from these bursts can disrupt mobile phone reception, and can also be messengers from the very early history of the universe. (2021-01-13)

Most distant quasar discovered sheds light on how black holes grow
A team of astronomers led by the University of Arizona has observed the most distant quasar to date. Fully formed just 670 million years after the Big Bang, the quasar is 1000 times more luminous than the Milky Way. It is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of the sun. The discovery provides insight into the formation of massive galaxies in the early universe. (2021-01-12)

Quasar discovery sets new distance record
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), along with other telescopes, have discovered the most distant quasar yet found. The bright quasar, powered by a supermassive black hole at the core of a galaxy, is seen as it was only 670 million years after the Big Bang, and is providing valuable clues about how such huge black holes and their host galaxies formed in the early Universe. (2021-01-12)

NASA missions help investigate an 'Old Faithful' active galaxy
Yellowstone National Park's Old Faithful geyser regularly blasts a jet of boiling water high in the air. Now, an international team of astronomers has discovered a cosmic equivalent, a distant galaxy that erupts roughly every 114 days. (2021-01-12)

'Old Faithful' cosmic eruption shows black hole ripping at star
You've heard of Old Faithful, the Yellowstone National Park geyser that erupts every hour or two, a geological phenomenon on a nearly predictable schedule. Now, an international group of scientists who study space have discovered an astronomical 'Old Faithful' - an eruption of light flashing about once every 114 days on a nearly predictable schedule. (2021-01-12)

To celebrate a new year, the NASA/ESA Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy. (2021-01-07)

In changing oceans, sea stars may be 'drowning'
New Cornell University-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress - literally 'drowning' in their own environment - as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe. (2021-01-06)

Prediabetes subtypes identified
All prediabetes is not the same: in people in the preliminary stages of type 2 diabetes, there are six clearly distinguishable subtypes, which differ in the development of the disease, diabetes risk, and the development of secondary diseases. The new classification can help in the future to prevent the manifestation of diabetes or the development of diabetes complications through targeted prevention. (2021-01-04)

Primordial black holes and the search for dark matter from the multiverse
In their paper, the team described a novel scenario for primordial black hole (PBH) formation and showed that the black holes from the ''multiverse'' scenario can be found using the Hyper Suprime-Cam (HSC) of the 8.2m Subaru Telescope, a gigantic digital camera--the management of which Kavli IPMU has played a crucial role--near the 4,200 meter summit of Mt. Mauna Kea in Hawaii. (2020-12-25)

How nearby galaxies form their stars
How stars form in galaxies remains a major open question in astrophysics. A new UZH study sheds new light on this topic with the help of a data-driven re-analysis of observational measurements. The star-formation activity of typical, nearby galaxies is found to scale proportionally with the amount of gas present in these galaxies. This points to the net gas supply from cosmic distances as the main driver of galactic star formation. (2020-12-21)

A pair of lonely planet-like objects born like stars
An international research team led by the University of Bern has discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun. (2020-12-16)

Exoplanet around distant star resembles reputed 'Planet Nine' in our solar system
Astronomers think planets can exist in orbits far from their star, and propose a two-step process: interactions with the star or inner planets kick it out of the inner system, and then a passing star stabilizes the orbit to keep it bound. Such a scenario could explain the hypothesized ''Planet Nine'' in our solar system. Astronomers has now confirmed that one binary star system, HD 106906, has a planet in a bound, highly eccentric orbit. (2020-12-10)
