Anisotropic zoning in the upper crust of the Tianshan Tectonic Belt
The collision between the Indian and Eurasian plates resulted in the formation of the Tianshan Tectonic Belt; however, the formation mechanism of Tianshan and the construction of a dynamic model explaining it remain to be realized and an integrated u.....»»
Scientists find evidence of geothermal activity within icy dwarf planets
A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or ev.....»»
Water is discovered on asteroids — by a defunct NASA mission
Astronomers used data from NASA's SOFIA mission, which ended in 2022, to spot water on the surface of two asteroids located in the asteroid belt of our solar system. A pioneering NASA 747 aircraft outfitted with a big telescope was retired a co.....»»
Fish in the upper Danube could be just as endangered in the future as in the past, but for different reasons
Rivers belong to the most threatened ecosystems on Earth. While many studies have projected climate change effects on species, little is known about the severity of these changes compared to historical alterations......»»
Introducing competition between schools involves a lot of work and major costs, Swedish study shows
After the introduction of the freedom to choose between upper secondary schools in 1992, it took nearly 10 years for upper secondary school heads in a municipality to start seeing themselves as competitors for school students. Any analysis of change.....»»
Secondary eyewall formation in upper- and lower-layer vertical wind shear simulated in idealized tropical cyclones
About 80% of intense tropical cyclones (TCs) possess concentric eyewalls—namely, the primary and secondary eyewalls. The intensity of the TC can vary considerably during secondary eyewall formation (SEF) and eyewall replacement, posing a great chal.....»»
Asteroid making its closest approach to Earth this week
On 4 February, asteroid 2011 MD will make its closest approach to the Earth. Though it will not be visible with the naked eye, the asteroid will pass 15,000,000 km away from Earth—much closer than those in the asteroid belt and less than 10% of the.....»»
Ancient rocks improve understanding of tectonic activity between earthquakes
Rocks once buried deep in ancient subduction zones—where tectonic plates collide—could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team from Penn State and.....»»
Black phosphorus propels spintronics with exceptional anisotropic spin transport
With modern electronic devices approaching the limits of Moore's law and the ongoing challenge of power dissipation in integrated circuit design, there is a need to explore alternative technologies beyond traditional electronics. Spintronics represen.....»»

Cosmic dawn observational progress with NenuFAR
The NenuFAR Cosmic Dawn project has taken an important step in the exploration of the Cosmic Dawn, this key period in our universe marked by the formation of the first stars. An upper limit on the amplitude of the neutral hydrogen fluctuations at 21.....»»
Discovery changes understanding of water"s history on the moon
New research from a Western University postdoctoral fellow shows the early lunar crust, which makes up the surface of the moon, was considerably enriched in water more than 4 billion years ago, counter to previously held understanding. The discovery.....»»
Anisotropic plasmon engineering unlocks multilevel polarized upconversion
National University of Singapore (NUS) researchers have introduced an upconversion plasmonphore platform to enable precise control over the polarization of isotropic upconversion nanoparticles (UCNPs). This is achieved by coupling upconversion activa.....»»
Webb finds signs of possible aurorae on isolated brown dwarf
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discov.....»»
Eureka shows off an innovative robot vacuum with a belt mopping system at CES 2024
The Eureka J20 features an impressive new belt mopping system, which is a big departure from the mopping plates and rotating pads seen on most products in 2023......»»
Researchers discover how atmospheric feldspar dust contributes to cloud formation
Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role. Fine powder carried by air influences cloud formation. Water molecules adhere better to feldspar d.....»»
How to instantly change text between upper, lower, and title case on a Mac
If you've ever found yourself needing to change the capitalization of an entire block of text at the same time, you'll know it can be mind-numbingly tedious. Thankfully, there is a way to make things easier on Mac.On macOS, there is a wealth of optio.....»»
Iron snow ebb and flow may cause magnetic fields to come and go
Just as snow crystals form in the upper atmosphere, then fall to lower, warmer elevations and melt, scientists believe a phenomenon called iron snow happens in the molten iron cores of some planetary bodies. Cooling near the core-mantle boundary crea.....»»
How many planets could be in the Kuiper Belt?
A recent study published in the Astrophysical Journal Letters investigates the potential existence of Mars-sized free-floating planets (FFPs)—also known as rogue planets, starless planets, and wandering planets—that could have been captured by ou.....»»
The zaï technique: How farmers in the Sahel grow crops with little to no water
Hubert Reeves once wrote that "on the cosmic scale, liquid water is rarer than gold". And what is true for the universe is even truer in the Sahel, the name given to the vast, arid belt that skirts the Sahara and stretches across Africa from east to.....»»
Controlling thermoelectric conversion in magnetic materials by magnetization direction
The National Institute for Materials Science (NIMS) has succeeded in directly observing the "anisotropic magneto-Thomson effect," a phenomenon in which the heat absorption/release proportional to an applied temperature difference and charge current (.....»»
