Sharks Use Earth"s Magnetic Field To Navigate the Seas
A new study suggests some sharks can read Earth's field like a map and use it to navigate the open seas. ScienceMag: The result adds sharks to the long list of animals -- including birds, sea turtles, and lobsters -- that navigate with a mysterious m.....»»
A clock in the rocks: What cosmic rays tell us about Earth"s changing surface and climate
How often do mountains collapse, volcanoes erupt or ice sheets melt?.....»»
The COVID-19 pandemic changed our patterns and behaviors, which in turn affected wildlife
The Earth now supports over eight billion people who collectively have transformed three-quarters of the planet's land surface for food, energy, shelter and other aspects of the human enterprise......»»
Life"s insiders: Decoding endosymbiosis with mathematics
Endosymbiosis, the intimate and long-term relationship where one organism lives inside another, is a cornerstone of life as we know it, and a key to the emergence of complex life on Earth. Many of the mysteries surrounding endosymbiosis are difficult.....»»
Fluidic telescope (FLUTE): Enabling the next generation of large space observatories
The future of space-based UV/optical/IR astronomy requires ever larger telescopes. The highest priority astrophysics targets, including Earth-like exoplanets, first generation stars, and early galaxies, are all extremely faint, which presents an ongo.....»»
The Great Observatory for Long Wavelengths (GO-LoW) proposal
Humankind has never before seen the low frequency radio sky. It is hidden from ground-based telescopes by the Earth's ionosphere and challenging to access from space with traditional missions because the long wavelengths involved (meter- to kilometer.....»»
Two small NASA satellites will measure soil moisture, volcanic gases
Two NASA pathfinding missions were recently deployed into low-Earth orbit, where they are demonstrating novel technologies for observing atmospheric gases, measuring freshwater, and even detecting signs of potential volcanic eruptions......»»
Weak magnetic field may have supported diversification of life on Earth
An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans, according to a paper published in Communications Earth & Env.....»»
Great white sharks off South Africa"s coast are protected by law, but not in practice—this needs to change
In less than eight years, white sharks in South Africa have all but disappeared from their historical hotspots in False Bay and Gansbaai, on the Western Cape coast. These areas were once known as the "white shark capital of the world" and were home t.....»»

EPA underestimates methane emissions from landfills and urban areas, researchers find
The Environmental Protection Agency (EPA) is underestimating methane emissions from landfills, urban areas and U.S. states, according to a new study led by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS)......»»
New computer algorithm supercharges climate models and could lead to better predictions of future climate change
Earth System Models—complex computer models that describe Earth processes and how they interact—are critical for predicting future climate change. By simulating the response of our land, oceans and atmosphere to manmade greenhouse gas emissions,.....»»
Researchers unlock potential of 2D magnetic devices for future computing
Imagine a future where computers can learn and make decisions in ways that mimic human thinking, but at a speed and efficiency that are orders of magnitude greater than the current capability of computers......»»
Marine sharks and rays "use" urea to delay reproduction, finds study
Urea—the main component of human urine—plays an important role in the timing of maturation of sharks, rays and other cartilaginous fish......»»
Building a strong cloud security posture
In this Help Net Security video, David Kellerman, Field CTO at Cymulate, discusses how cloud security still seems to lag even as the cloud grows in popularity and usage. Many leaders are unaware that they need to secure the cloud the same way they wo.....»»
Start today: Save with Dell and shape a more sustainable future for us all
The Dell sustainability mission for Earth Day 2024 means you can save while also remaining eco-conscious, something we desperately need in today's world......»»
Launch date set for NASA"s PREFIRE mission to study polar energy loss
NASA and Rocket Lab are targeting no earlier than Wednesday, May 22, 2024, for the first of two launches of the agency's PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission to study heat loss to space in Earth's polar regions......»»
Scientists show that ancient village adapted to drought, rising seas
Around 6,200 BCE, the climate changed. Global temperatures dropped, sea levels rose and the southern Levant, including modern-day Israel, the Palestinian territories, Jordan, Lebanon, southern Syria and the Sinai desert, entered a period of drought......»»
An AI model to reduce uncertainty in evapotranspiration prediction
When scientists look at the Earth's available water for ecosystem services, they don't just look at precipitation. They must also account for water moving from the ground to the atmosphere, a process known as evapotranspiration (ET)......»»
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modeling climate changes from times long past. And they show that plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth......»»
