Earth in hot water? Worries over sudden ocean warming spike
The world's oceans have suddenly spiked much hotter and well above record levels in the last few weeks, with scientists trying to figure out what it means and whether it forecasts a surge in atmospheric warming......»»
The frozen carbon of the northern permafrost is on the move—we estimated by how much
Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the Arctic. This region is warming two to four times faster than the global average......»»
New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
Earth 2 at 30: A look back at NBC’s big swing at sci-fi in the early ’90s

Braving sharks and hordes of urchins, scientists are growing kelp one forest at a time
The weathered UC Davis Marine Laboratory looms in thick fog on the edge of the ocean near Bodega Bay. Inside, an experiment is playing out that gives a badly-needed boost to Northern California's kelp forests—underwater cathedrals of green and gold.....»»
"The nastiest soils on Earth" are getting recognized as a bigger problem
Acid sulfate soils are characterized by their orange hue and their tendency to kill surrounding vegetation and fish. Anders Johnson's extensive research along Sweden's coastline reveals the widespread presence of these soils, underscoring their signi.....»»
Water overuse in Brazil"s MATOPIBA region could mean failure to meet up to 40% of local demand for crop irrigation
Considered one of the fastest-growing agricultural frontiers in Brazil, and the area with the highest greenhouse gas emissions in the Cerrado, Brazil's savanna-type biome, the region known as MATOPIBA, risks facing water shortages in the years ahead......»»
Decades after global regulations, the Arctic Ocean"s legacy persistent organic pollutants haven"t dropped
The presence of persistent organic pollutants (POPs) in all the world's oceans but one has been in steady decline since 2001, when 152 countries agreed on a comprehensive global ban. The exception has been the Arctic Ocean, which has seen a sharp ris.....»»
Scientists find key to engineering water-responsive biopolymers
Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have developed a novel approach to better understand and predict the behaviors of water-responsive materials—solid matter that can change shape by absorbing.....»»
Text and facial expressions drive success in charitable crowdfunding
A study conducted by researches from Ocean University of China, published in Financial Innovation, presents a novel model to investigate the role of emotions in charitable crowdfunding. Grounded in emotional contagion theory and language-mediated ass.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
Earth underwent a massive, rapid melting period after the last global ice age, new study suggests
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—other.....»»
M4 24-inch iMac vs M3 24-inch iMac compared -- Apple"s iconic Mac gets a speed boost
Apple's refreshed M4 24-inch iMac sports a fast chip, but that isn't the only reason to upgrade. Here's how the hot new model compares to the year-old M3 iMac that it replaces.Apple's M4 iMac hasn't changed all that much.Apple's launch of the new M4.....»»
Next-generation space materials blast off for tests on ISS
A new generation of space materials left Earth on November 5 as they head to the International Space Station (ISS) to undergo testing in the brutal conditions of low Earth orbit......»»
Moon waves goodbye to Hera
As ESA's Hera mission for planetary defense departed its homeworld, it looked back to Earth to show the moon orbiting around it. In this sequence of images the terrestrial disk gradually shrinks as the spacecraft recedes away from it, and the moon mo.....»»
Valencia floods: Warming climate is making once-rare weather more common and more destructive, says researcher
In the last few days, a seasonal weather system known in Spain as the "cold drop" or DANA (an acronym of "depresión aislada en niveles altos": isolated depression at high levels) has caused heavy rain and flooding across Spain's Mediterranean coast.....»»
Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
