Scientists and space explorers have been on the hunt to determine where and how much ice is present on the Moon. Water ice would be an important resource at a future lunar base, as it could be used to support humans or be broken down to hydrogen and oxygen, key components of rocket fuel. University of Hawai’i at Manoa researchers are using two innovative approaches to advance the search for ice on the Moon.

Water ice was previously detected in the permanently shaded regions of the Moon’s north and south poles by Shuai Li, assistant researcher at the Hawai’i Institute o...

Long COVID can result in increased risk for a variety of serious health problems for young people, including those affecting the kidney, gut, and cardiovascular system, according to a group of new studies led by investigators at the Perelman School of Medicine at the University of Pennsylvania.

“While most public attention has focused on the acute phase of COVID-19, our findings reveal children face significant long-term health risks that clinicians need to monitor,” said senior author Yong Chen, Ph.D., a professor in the Department of Biostatistics and Epidemiology. The studies were conducted under the Researching COVID to Enhance Recovery (RECOVER) Initiative, a special project including more than two dozen health care institutions.

Superradiant Smith-Purcell radiation (S-SPR) is a kind of free electron radiation with a train of free electron bunches passing over a periodic grating. In theory, the ultra-narrow spectral linewidth of S-SPR could be realized which would be greatly beneficial to various applications such as imaging, sensing and communication.

However, in the free electron accelerators, customized setups and orotr...

By analyzing the available observational data, astronomers from the Tribhuvan University in Nepal and elsewhere have investigated the properties of a compact dwarf galaxy designated SDSS J134313.15+364457.5 (or J1343+3644 for short). As a result, they found that J1343+3644 will evolve into a compact elliptical galaxy.

The new finding is reported in a paper published April 14 on the arXiv pre-print server.

In general, dwarf galaxies are the most numerous in the universe when compared to other galaxies but are difficult to detect due to their low luminos...
