NASA's Orion spacecraft en route for the Moon, with the Earth in the background, in a photo released by NASA in November 2022. Exceeding expectations On the third day after taking off from Florida bound for the Moon, the Orion spacecraft is "surpassing effectiveness expectations," NASA officials stated on Friday. First flight aims to ensure vehicle safety The...
(Guido Mieth/Getty Images) Ice characteristics Ice is not constantly ice all the way through. Even at temperatures level well below freezing, its surface area can be coated in a membrane of quasi-liquid atoms, with its density typically only a few nanometers. Its formation procedure is referred to as premelting (or 'surface melting'), which is why your ice...
Nanoparticles accumulate in tumor. Credit: Olena Taratula, Oleh Taratula, OSU College of Pharmacy Oregon State College researchers have invented a way to make magnetic nanoparticles that obtain hotter than any previous nanoparticle, improving their cancer-combating ability. Faculty from the OSU University of Drugstore led a partnership that created an advanced thermal decomposition technique for creating nanoparticles...
The Heterobrachia was little affected by the end-Triassic mass extinction, possibly because of a flexible mode of feeding of the larvae, an adaptation to relatively warm temperatures, and a flexible attachment of the mantle that allowed for covering the shell.

In their paper released in the journal Nature Geoscience, the team assesses rainfall records in addition to hydrologically heavy leaf place indices to calculate modifications in surface area water over...
An artist's impression of the LOFTID aeroshell. Credit: NASA just recently turned one sci-fi technology into reality by crashing a spacecraft into one asteroid with its Dual Asteroid Redirection Test (DART) mission. Now, the space company aims to test a large inflatable aeroshell that can one day be used to deploy massive payloads on Mars...
Planet Mars stock photo. Credit: iStock Ancient microbes on Mars likely triggered a climate change that led to their own demise, a report from Space.com explains. The study was published in Nature Astronomy, and it details how simple microbes that fed on hydrogen and excreted methane were likely abundant on Mars approximately 3.7 billion years back....
Credit: Pixabay/CC0 Public Domain Scientists have used Internet transmitting fiber-optic cables to overcome a long-standing geophysical difficulty: identifying where seismic sound in the ocean originates. Small vibrations of Earth called microseisms are ubiquitous. Yet, researchers have not had one way to pinpoint their sources in the ocean. An innovative use of telecom equipment has changed...
Melting glacier. credit: iStock/ fredtamashiro The Thwaites Glacier is holding onto Antarctica's ice sheet by its fingernails, and the globe might see significant changes over the next year or two, researchers have alerted in a recently released study, CNN reported. As the world warms, giant sheets of ice near the poles have been melting off. Previously...
Tokamak geometry and the parameter evolution of a FIRE mode. a, The plasma configuration of a FIRE mode in KSTAR. Credit: Nature (2022). DOI: 10.1038/s41586-022-05008-1 A team of researchers connected with several institutions in South Korea, working with two coworkers from Princeton University and one from Columbia University, has accomplished a new milestone in the development of...
