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.

Ancient climate change solves mystery of vanished South African lakes      (via sciencedaily.com)     Original source 

New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.

Half of world's largest lakes losing water      (via sciencedaily.com)     Original source 

Fifty-three percent of the world's largest freshwater lakes are in decline, storing less water than they did three decades ago, according to a new study. The study analyzed satellite observations dating back decades to measure changes in water levels in nearly 2,000 of the world's biggest lakes and reservoirs. It found that climate change, human consumption and sedimentation are responsible.

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.

'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.

Better than humans: Artificial intelligence in intensive care units      (via sciencedaily.com)     Original source 

With the help of extensive data from intensive care units of various hospitals, an artificial intelligence was developed that provides suggestions for the treatment of people who require intensive care due to sepsis. Analyses show that artificial intelligence already surpasses the quality of human decisions. However, it is now important to also discuss the legal aspects of such methods.

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.

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.

West Antarctic Ice Sheet retreated far inland, re-advanced since last Ice Age      (via sciencedaily.com)     Original source 

The West Antarctic Ice Sheet is melting rapidly, raising concerns it could cross a tipping point of irreversible retreat in the next few decades if global temperatures rise 1.5 to 2.0 degrees Celsius (2.7 to 3.8 degrees Fahrenheit) above preindustrial levels. New research finds that 6,000 years ago, the grounded edge of the ice sheet may have been as far as 250 kilometers (160 miles) inland from its current location, suggesting the ice retreated deep into the continent after the end of the last ice age and re-advanced before modern retreat began.

Highly dexterous robot hand can operate in the dark -- just like us      (via sciencedaily.com)     Original source 

Researchers demonstrated a highly dexterous robot hand, one that combines an advanced sense of touch with motor learning algorithms in order to achieve a high level of dexterity. In addition, the hand worked without any external cameras -- it's immune to lighting, occlusion, or similar issues. Because the hand doesn't rely on vision to manipulate objects, it can do so in difficult lighting conditions that would confuse vision-based algorithms -- it even operates in the dark.
