The speed of water flow is a limiting factor in many membrane-based industrial processes, including desalination, molecular separation and osmotic power generation.

If your idea of conspiracy theories entails aliens, UFOs, governmental cover-ups at Roswell Air Force Base, and the melody of The X-Files—you're not alone. That was, indeed, the classic notion, says Scott Tyson, an assistant professor of political science at the University of Rochester.

Most cities in São Paulo state (Brazil) have low potential capacity to adapt to climate change in terms of the ability to formulate public policy that facilitates the revamping of their housing and transportation systems, for example, to account for the impact of climate change.

Using drones and artificial intelligence to monitor large colonies of seabirds can be as effective as traditional on-the-ground methods, while reducing costs, labor and the risk of human error, a new study finds.

A research team from the University of Massachusetts Amherst has created an electronic microsystem that can intelligently respond to information inputs without any external energy input, much like a self-autonomous living organism. The microsystem is constructed from a novel type of electronics that can process ultralow electronic signals and incorporates a device that can generate electricity "out of thin air" from the ambient environment.

Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area.

Researchers at the University of Illinois Chicago have developed a novel continuous-flow microfluidic device that may help scientists and pharmaceutical companies more effectively study drug compounds and their crystalline shapes and structures, which are key components for drug stability.

Last year, Anupam Mazumdar, a physicist from the University of Groningen, together with colleagues from the UK proposed an experiment that could conclusively prove whether gravity is a quantum phenomenon. This experiment would focus on observing two relatively large, entangled quantum systems in free fall. In a new article, published on 4 June in Physical Review Research, the scientists describe in more detail how two types of noise could be reduced. They suggest that quantum interference could be...

Monarch butterflies raised indoors still know how to fly south if given enough time to orient themselves, according to new University of Guelph research.

Eggs littered the sand, but there was no sign of life around or in them.

The U.S. 9th Circuit Court of Appeals this week rejected a decision by the Trump administration that Pacific walrus no longer qualified to be listed as a threatened species.

Newly vaccinated travelers enjoying a return to trips abroad may find a drug-resistant "superbug" hitching a ride in their gut, a study in Genome Medicine says.

The University of North Florida archaeology team is now fairly confident they have located the lost Indigenous northeast Florida community of Sarabay, a settlement mentioned in both French and Spanish documents dating to the 1560s but had not been discovered until now.

Potentially lethal marine algae blooms have not increased in number over the last three decades, but pose a serious threat to aquaculture, according to a UN global assessment released Tuesday.

Using the Hubble Space Telescope (HST), astronomers have conducted near-ultraviolet through near-infrared observations of a young planetary nebula (PN) known as NGC 6302. Results of the monitoring campaign, presented May 28 on arXiv.org, could help us better understand the nature of this PN.

A team of archaeologists with the Glacier Archaeology Program in Innlandet have discovered a candle box in the Lendbreen glacier in Norway's Breheimen National Park. The team has been posting its findings on their Facebook page.

On the 14th of August 2019, the LIGO-Virgo collaboration detected a gravitational wave signal believed to be associated with the merging of a binary stellar system composed of a black hole with a mass of 23 times the mass of the sun (M⊙) and a compact object with a mass of about 2.6 M⊙. The nature of GW190814ʼs secondary star is enigmatic, since, according to the current astronomical observations, it could be the heaviest neutron star or the lightest black hole ever observed.
