COLUMBUS, Ohio – Some Black youth feel less safe when they visit predominantly white areas of their city, a new study in Columbus has found.   And it was those Black kids who spent the most time in white-dominated areas who felt less safe, said Christopher Browning, lead author of the study and professor of sociology at The Ohio State University.   “Familiarity with white neighborhoods doesn’t make Black kids feel more comfortable and safer. In fact, familiarity seems to reveal ...

LAWRENCE — A survey of orchid bees in the Brazilian Amazon state of Rondônia, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics. The findings, from a researcher at the University of Kansas, are published today in the peer-reviewed journal Biological Conservation. “This study on orchid bees was an add-on to previous research on stingless bees. Orchid bees are so easy to collect, so we added them to ...

The Tibetan Plateau is a prevalent region for deep convection owing to its unique thermodynamic forcing. Deep convection can exist as isolated deep convection (IDC), which is small in size, or mesoscale convective systems (MCSs), which are convective storms organized into larger and longer-lived systems. Most previous research has focused on MCSs over the Tibetan Plateau, but less so on IDC systems (hereafter, IDCs). Dr. Ying Na from Wuxi University, and Dr. Chaofan Li from the Institute of Atmospheric Physics, Chinese Academy of Sciences, China, examined the climatological features of IDCs by using high-resolution satellite observations in June to September ...

Understanding the mutation and evolution of viruses (such as SARS-CoV-2) is crucial for effective public health management and response. Traditional epidemiological models often assume that viral transmissibility and pathogenicity remain constant during disease transmission, ignoring the fact that viruses continuously evolve through natural selection and random mutations. This simplification limits the accuracy of these models in predicting epidemic trends, especially when facing rapidly mutating viruses. To overcome these limitations, ...

When scuba divers need to say “I’m okay” or “Shark!” to their dive partners, they use hand signals to communicate visually. But sometimes these movements are difficult to see. Now, researchers reporting in ACS Nano have constructed a waterproof “e-glove” that wirelessly transmits hand gestures made underwater to a computer that translates them into messages. The new technology could someday help divers communicate better with each other and with boat crews on the surface. E-gloves — gloves fitted ...

A team of researchers at Nagoya University in Japan has discovered that aldehydes are metabolic byproducts associated with premature aging. Published in Nature Cell Biology, their findings reveal insights into premature aging diseases and potential strategies to combat aging in healthy individuals such as controlling exposure to aldehyde-inducing substances including alcohol, pollution, and smoke.  A person's health can be harmed by aldehydes. However, the group’s findings suggest these detrimental effects also include aging. The team who made this discovery included Yasuyoshi Oka, Yuka Nakazawa, Mayuko Shimada, and Tomoo Ogi of Nagoya University.  “DNA ...

Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering. Among the troublesome hurdles of this scaling-up race is refining how qubits are measured. Devices called parametric amplifiers are traditionally used to do these measurements. But as the name suggests, the device amplifies weak signals picked up from the qubits to conduct the readout, which causes unwanted noise and can lead to decoherence of the qubits if not protected by additional large components. More importantly, the bulky size of the amplification chain becomes technically challenging to work around as qubit counts increase ...

Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other planets can develop life, ranging from plants to animals and humans. The study, published today in Nature Geoscience and led by a researcher at the University of Bristol, reveals for the first time how the build up of carbon-rich rocks has accelerated oxygen production and its release into the atmosphere. Until now the exact nature of how the atmosphere became oxygen-rich has long eluded scientists and generated conflicting explanations. As carbon dioxide is steadily ...

Tokyo, Japan – The idea of growing a functioning human brain-like tissues in a dish has always sounded pretty far-fetched, even to researchers in the field. Towards the future goal, a Japanese and French research team has developed a technique for connecting lab-grown brain-mimicking tissue in a way that resembles circuits in our brain. It is challenging to study exact mechanisms of the brain development and functions. Animal studies are limited by differences between species in brain structure and function, and brain cells grown in the lab tend to lack the characteristic ...
