Making sense of the nonsensical: Black holes and the simulation library
The international Event Horizon Telescope collaboration has snapped a second image of a black hole—this time at the center of our own Milky Way galaxy. But to give the image meaning, the collaboration had to compare it with black hole simulations. After mobilizing more than 300 scientists and engineers to establish a network of synchronized […]
Development of high-durability single-atomic catalysts using industrial humidifier
Fuel cell electric vehicles (FCEVs) are an eco-friendly means of transportation that will replace internal combustion locomotives. FCEVs offer several advantages such as short charging time and long mileage. However, the excessive cost of platinum used as a fuel cell catalyst leads to limited supply of FCEVs. There has been extensive research on non-precious metal […]
A vertical matrix X-ray detector for multi-energy discrimination
There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible light in the wavelength range of 400-780 nm lets us see the colorful world. In the wavelength range […]
Nanomaterial-Based Virus Sensors
The ongoing coronavirus disease 2019 (COVID-19) pandemic highlighted the need to develop effective diagnostic tools to rapidly identify the presence of novel viruses and ultimately reduce their transmission. In particular, nanomaterial-based virus sensors have been widely studied for several decades and present a unique opportunity to resolve this issue. Over the past two decades, several […]

Study reveals new way to reconstruct past climate on Mars
A study led by a Monash University geologist has provided fresh evidence for when high rates of erosion occurred throughout history of Mars. The findings, published today in Geology date when climate was far more erosive in Mars’ past—with the implication that there were sustained periods of time when liquid water moved across the planet’s […]
Black hole winds are no longer as they used to be
During the first billion years of the universe, black hole winds at the centers of galaxies were much more frequent and more powerful than those observed in today’s galaxies, some 13 billion years later. Such winds were so mighty that they slowed down the growth of the supermassive black holes from which they originate. These […]
NASA supports Event Horizon Telescope in studying Milky Way’s black hole
The black hole at the center of our galaxy is the subject of a groundbreaking new image from the Event Horizon Telescope collaboration. As the Event Horizon Telescope collected data for its remarkable new image of the Milky Way’s supermassive black hole, a legion of other telescopes including three NASA X-ray observatories in space was […]
A tissue curves increase the volume of the cells that compose it
How do our cells organize themselves to give their final shape to our organs? The answer lies in morphogenesis, the set of mechanisms that regulate their distribution in space during embryonic development. A team from the University of Geneva (UNIGE) has just made a surprising discovery in this field: when a tissue curves, the volume […]
