These long-necked reptiles were decapitated by their predators, fossil evidence confirms      (via sciencedaily.com)     Original source 

In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today. While it was clearly a successful evolutionary strategy, paleontologists have long suspected that their long-necked bodies made them vulnerable to predators. Now, after almost 200 years of continued research, direct fossil evidence confirms this scenario for the first time in the most graphic way imaginable.

A new tool to study complex genome interactions      (via sciencedaily.com)     Original source 

Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.

Researchers want drivers to see clearly on the road      (via sciencedaily.com)     Original source 

Every year, sun glare contributes to around 3,000 crashes in the United States. Researchers are helping to mitigate this problem by examining what drivers are likely to do when faced with sun glare.

How fungus farming ants keep their gardens healthy      (via sciencedaily.com)     Original source 

'Weed early and often' is the key to a productive garden. Interestingly, certain species of ants are also avid gardeners, a practice they've refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report how ants distinguish the good fungus from the bad.

Study finds combustion from gas stoves can raise indoor levels of chemical linked to a higher risk of blood cell cancers      (via sciencedaily.com)     Original source 

About 47 million homes use natural gas or propane-burning cooktops and ovens. Researchers found that cooking with gas stoves can raise indoor levels of the carcinogen benzene above those found in secondhand smoke.

Fossil study sheds light on famous spirals found in nature      (via sciencedaily.com)     Original source 

A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.

Advanced universal control system may revolutionize lower limb exoskeleton control and optimize user experience      (via sciencedaily.com)     Original source 

A team of researchers has developed a new method for controlling lower limb exoskeletons using deep reinforcement learning. The method enables more robust and natural walking control for users of lower limb exoskeletons. "Robust walking control of a lower limb rehabilitation exoskeleton coupled with a musculoskeletal model via deep reinforcement learning" is available open access.

Navigating underground with cosmic-ray muons      (via sciencedaily.com)     Original source 

Superfast, subatomic-sized particles called muons have been used to wirelessly navigate underground in a reportedly world first. By using muon-detecting ground stations synchronized with an underground muon-detecting receiver, researchers were able to calculate the receiver's position in the basement of a six-story building. As GPS cannot penetrate rock or water, this new technology could be used in future search and rescue efforts, to monitor undersea volcanoes, and guide autonomous vehicles underground and underwater.

Change food choices to increase chances of tackling global warming      (via sciencedaily.com)     Original source 

Action to protect the planet against the impact of climate change will fall short unless we reduce greenhouse gas (GHG) emissions from the global food system, which now makes up a third of human-made GHG emissions, a new study reveals.

How will a warming world impact the Earth's ability to offset our carbon emissions?      (via sciencedaily.com)     Original source 

New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.

We've pumped so much groundwater that we've nudged Earth's spin      (via sciencedaily.com)     Original source 

By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study.

Close up on aging reveals how different cell types in the body age at different pace      (via sciencedaily.com)     Original source 

A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.

Cleaner air with a cold catalytic converter      (via sciencedaily.com)     Original source 

Although passenger vehicle catalytic converters have been mandatory for over 30 years, there is still plenty of room for improvement. For instance, they only work correctly when the engine is sufficiently hot, which is not always the case, especially with hybrid vehicles. Researchers have now developed an improved catalyst that can properly purify exhaust gases even at room temperature.
