Rocks unravel the secrets of the Earth"s magnetic field
More than 350 million years ago something odd was going on with the Earth's magnetic field. Scientists now propose that the field was really weak, which may have affected life on our planet......»»
Mantle heat may have boosted Earth"s crust 3 billion years ago
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare......»»
Researchers show it"s possible to teach old magnetic cilia new tricks
Magnetic cilia—artificial hairs whose movement is powered by embedded magnetic particles—have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cili.....»»
A NASA rover has reached a promising place to search for fossilized life on Mars
While we go about our daily lives on Earth, a nuclear-powered robot the size of a small car is trundling around Mars looking for fossils. Unlike its predecessor Curiosity, NASA's Perseverance rover is explicitly intended to "search for potential evid.....»»
How evolution has optimized the magnetic sensor in birds
Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass. A team led by biologists Dr. Corinna Langebrake and Prof. Dr. Miriam Liedvogel from the University of Oldenburg and t.....»»
Australia"s tall, wet forests were not open and park-like when colonists arrived—and we shouldn"t be burning them
Some reports and popular books, such as Bill Gammage's Biggest Estate on Earth, have argued that extensive areas of Australia's forests were kept open through frequent burning by First Nations people. Advocates for widespread thinning and burning of.....»»
Hidden biosphere discovered beneath world"s driest hot desert

Spintronics is a field garnering immense attention for its range of potential advantages for conventional electronics. These include reducing power consumption, high-speed operation, non-volatility, and the potential for new functionalities......»»
From the coast to the deep sea, changing oxygen levels affect marine life in different ways
Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels change within the course.....»»
2 former dealership employees who started new marketing firm settle lawsuit
A Massachusetts dealership has settled a lawsuit that accused two former employees of breach of loyalty, misappropriation of trade secrets and other claims for setting up a competing dealer-to-dealer digital marketing agency......»»
NASA to overhaul mission returning samples from Mars—here"s why it must and will go ahead
NASA recently announced that it is seeking new ways to complete the return to Earth of rock cores drilled by the Perseverance Rover in the Jezero Crater on Mars. This has led to some anxiety among space scientists, who view the Mars Sample Return (MS.....»»
Observations explore globular cluster system in the galaxy NGC 4262
Using the Canada-France-Hawaii Telescope (CFHT), Indian astronomers have performed wide and deep field observations of a polar ring galaxy known as NGC 4262. Results of the observational campaign, published April 15 on the pre-print server arXiv, she.....»»
Fossil frogs share their skincare secrets: Analysis of 45-million-year-old soft tissues
Paleontologists at University College Cork (UCC), Ireland, have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts—it's all down to their skin......»»
A first glimpse at our galaxy"s magnetic field in 3D
Thanks to new sophisticated techniques and state-of-the-art facilities, astronomy has entered a new era in which the depth of the sky can finally be accessed. The ingredients of our cosmic home, the Milky Way galaxy—stars, gas, magnetic fields—ca.....»»
Breaking boundaries in tiny labs: New technology using sound waves has implications for nanoparticle manipulation
