New method predicts extreme events more accurately      (via sciencedaily.com)     Original source 

A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.

Extinct offshore volcano could store gigatons of carbon dioxide      (via sciencedaily.com)     Original source 

A new study concludes that an extinct volcano off the shore of Portugal could store as much as 1.2-8.6 gigatons of carbon dioxide, the equivalent of ~24-125 years of the country's industrial emissions. For context, in 2022 a total of 42.6 megatons (0.0426 gigatons) of carbon dioxide was removed from the atmosphere by international carbon capture and storage efforts, according to the Global CCS Institute. The new study suggests that carbon capture and storage in offshore underwater volcanoes could be a promising new direction for removal and storage of much larger volumes of the greenhouse gas from the atmosphere.

Researchers build bee robot that can twist      (via sciencedaily.com)     Original source 

A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.

Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world      (via sciencedaily.com)     Original source 

Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.

Wiring up quantum circuits with light      (via sciencedaily.com)     Original source 

The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical and microwave photons that could lay the foundation for such a future quantum network.

Past climate change to blame for Antarctica's giant underwater landslides      (via sciencedaily.com)     Original source 

Scientists found weak, biologically-rich layers of sediments hundreds of meters beneath the seafloor which crumbled as oceans warmed and ice sheets declined. The landslides were discovered in the eastern Ross Sea in 2017, by an international team of scientists during the Italian ODYSSEA expedition, and scientists revisited the area in 2018 as part of the International Ocean Discovery Program (IODP) Expedition 374 where they collected sediment cores to understand what caused them.

Physicists take the temperature of fluid flows and discover new role for turbulence      (via sciencedaily.com)     Original source 

A team of physicists has discovered a new role for a specific type of turbulence -- a finding that sheds light on fluid flows ranging from the Earth's liquid core to boiling water.

'Warm Ice Age' changed climate cycles      (via sciencedaily.com)     Original source 

Approximately 700,000 years ago, a 'warm ice age' permanently changed the climate cycles on Earth. During this exceptionally warm and moist period, the polar glaciers greatly expanded. A research team identified this seemingly paradoxical connection. The shift in the Earth's climate represents a critical step in our planet's later climate development.

Out of this world control on Ice Age cycles      (via sciencedaily.com)     Original source 

A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show that the glacial cycle was driven primarily by astronomical forces in quite a different way than it works in the modern age. These results will help us to better understand the past, present, and future of ice sheets and the Earth's climate.

Great Bas­in: His­tory of water sup­ply in one of the dri­est regions in the USA      (via sciencedaily.com)     Original source 

An international team has reconstructed the evolution of groundwater in the Great Basin, USA -- one of the driest regions on Earth -- up to 350,000 years into the past with unprecedented accuracy. The results shed new light on the effects of climate change on water supply and provide important insights for the sustainable use of groundwater resources.

Robotic proxy brings remote users to life in real time      (via sciencedaily.com)     Original source 

Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.

How life and geology worked together to forge Earth's nutrient rich crust      (via sciencedaily.com)     Original source 

Around 500 million years ago life in the oceans rapidly diversified. In the blink of an eye -- at least in geological terms -- life transformed from simple, soft-bodied creatures to complex multicellular organisms with shells and skeletons. Now, research has shown that the diversification of life at this time also led to a drastic change in the chemistry of Earth's crust -- the uppermost layer we walk on and, crucially, the layer which provides many of the nutrients essential to life.

A cocktail party of 3D-printed robot heads      (via sciencedaily.com)     Original source 

Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of an augmented listening laboratory. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements.

Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes      (via sciencedaily.com)     Original source 

Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.

New clues about the rise of Earth's continents      (via sciencedaily.com)     Original source 

New research deepens the understanding of Earth's crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic crust. The iron-poor composition of continental crust is a major reason why vast portions of the Earth's surface stand above sea level as dry land, making terrestrial life possible today. The study uses laboratory experiments to show that the iron-depleted, oxidized chemistry typical of Earth's continental crust likely did not come from crystallization of the mineral garnet, as a popular explanation proposed in 2018.

The future of data storage lies in DNA microcapsules      (via sciencedaily.com)     Original source 

Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.

A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads      (via sciencedaily.com)     Original source 

It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.
