Fluid flow stimulates chemosynthesis in a "Greek salad" of hydrothermal microbes
Most visitors to Paliochori Beach on the Greek island Milos may not be aware of the bay's shallow-water hydrothermal community, a veritable Greek salad of microbes, that is within snorkeling distance from the shoreline......»»
Effects of porosity on piezoelectric characteristics of polyvinylidene fluoride films for biomedical applications
Polyvinylidene fluoride (PVDF) is a piezoelectric polymer material that has shown great aptitude as a pressure and flow sensor, especially in biomedical applications. However, most of the PVDF thin film sensors have low sensitivity and resolution due.....»»
New EU deal legalizes transatlantic data transfers once again
The European Union has agreed to a proposal to allow companies like Facebook, Google, and Apple to store data about European users in the United States, once again allowing data to flow across the Atlantic.European flagsIn 2020, an EU court decided t.....»»
A new technique uses remote images to gauge the strength of ancient and active rivers beyond Earth
Rivers have flowed on two other worlds in the solar system besides Earth: Mars, where dry tracks and craters are all that's left of ancient rivers and lakes, and Titan, Saturn's largest moon, where rivers of liquid methane still flow today......»»
Scientists enrich nitric oxide-reducing microbes in bioreactor
Nitric oxide (NO) is a fascinating and versatile molecule, important for all living things as well as the environment. It is highly reactive and toxic, organisms use it as a signaling molecule, it depletes the ozone layer in our planet's atmosphere,.....»»
Southwest Indian Ocean Ridge develops diverse hydrothermal systems, potential large polymetallic deposits
The research findings of Dr. Tao Chunhui, a senior researcher from the Second Institute of Oceanography, Ministry of Natural Resources, were published in Science China Earth Sciences. Over a decade, Dr. Tao's research team conducted investigations in.....»»
Extracellular cytochrome nanowires appear to be ubiquitous in microbes
A Geobacter bacteria isolated from a contaminated ditch in Oklahoma has an unusual appendage—a long extracellular nanowire that can conduct electricity. The electron transport chain in this nanowire carries electrons from the bacteria to an insolub.....»»
Financial transparency index helps track the flow of "dark money" in politics
Not all nonprofits are created equal—and some exist mainly to capitalize on a tax law loophole that allows them to anonymously funnel donations to political causes. New University of Oregon research proposes an index that rates the financial transp.....»»
One shot of a kidney protein gave monkeys a brain boost
An early experiment suggests that an injection of klotho improves working memory. Enlarge Klotho, the ancient Greek goddess of fate, is responsible for spinning the thread of life. In the human body, a protein with the.....»»
First direct visualization of a zero-field pair density wave
In the field of superconductivity—the phenomenon in which electrons can flow through a material with essentially zero resistance—the "holy grail" of discovery is a superconductor that can perform under everyday temperatures and pressures. Such a.....»»
Volcanic sulfur flows observed and recorded in northern Chile
A small international team of vulcanologists has observed a rarely seen event—a sulfur flow from a volcano—in northern Chile. In their paper published in the journal Frontiers in Earth Science, the group describes how they happened to observe the.....»»

Modern Hunter-Gatherers Have Thriving Gut Microbiome, Compared with Californians
A Western lifestyle seems to diminish the diversity of gut microbes.....»»
Stronger winds shift water from the Labrador Current eastward, with dire consequences for marine ecosystems
Changes to the flow of the Labrador Current along the coast of Newfoundland and Labrador to Nova Scotia are leading to sudden warmings or drops in the oxygen levels of the waters in several regions including the St. Lawrence Gulf and Estuary. This ch.....»»
Host genetics shown to play a significant role in the composition of switchgrass root microbiomes
Plants provide a home for a wide diversity of microbes, especially in their roots. In turn, these communities can provide important benefits for the host. A study published in Current Biology investigated how the genetics of host plants determine the.....»»
Novel algorithm improves understanding of plasma shock waves in space
Imagine the explosive disturbance caused by a jet going supersonic. A similar shock wave occurs when subatomic particles known as "solar wind" flow from the sun and strike the Earth's magnetic field. Now, scientists have used a recently developed tec.....»»
Better predictions of wildfire spread may sit above the treetops
When the skies above Palo Alto darkened with smoke from the Camp Fire in 2018, Stanford researcher Hayoon Chung was in a fluid mechanics lab on campus studying how ocean currents flowed over patches of seagrass. She wondered if patterns similar to th.....»»
Magnetic bacteria provide clues for the early diversification of bacteria
Magnetotactic bacteria, which can align with the Earth's magnetic field, have been discovered in a new location. Previously observed on land and in shallow water, analysis of a hydrothermal vent has proven that they can also survive deep under the oc.....»»
Flow of water on a carbon surface is governed by quantum friction, says study
Water and carbon make a quantum couple: the flow of water on a carbon surface is governed by an unusual phenomenon dubbed quantum friction. A new work published in Nature Nanotechnology experimentally demonstrates this phenomenon—which was predicte.....»»
How proteins protect mammalian sperm on their way to the egg cell
Mammalian seminal fluid contains a variety of proteins secreted by the accessory sex glands that are important for the processes involved in fertilization. One of these proteins, which is found in ungulates—and in particularly large quantities in b.....»»
A new approach to controlling the properties of turbulence
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating it and controlling its pro.....»»
