Phys.org / Dating a North American rock art tradition that lasted 175 generations
The Pecos River murals are a stunning collection of monumental, multicolored rock paintings in limestone rock shelters across southwest Texas and northern Mexico. They depict human-like figures that reach up to eight meters ...
Phys.org / A novel role for Zer1 may help cells combat neurodegeneration and oxidative stress
A team of researchers from Academia Sinica and National Taiwan University has identified the Drosophila Cul2 substrate adaptor DmZer1 as a key regulator of protein quality control, acting at the intersection of two major ...
Phys.org / The mystery of the missing deep ocean carbon fixers
In a step toward better understanding how the ocean sequesters carbon, new findings from UC Santa Barbara researchers and collaborators challenge the current view of how carbon dioxide is "fixed" in the sunless ocean depths. ...
Phys.org / Employee delight found to boost workplace motivation and team performance
Eight out of 10 people in Spain admit to being satisfied with their jobs, according to a survey by the 40dB Institute. But what would happen if these same workers were asked about their emotions and experiences? What if they ...
Phys.org / Deforestation has turned Africa's forests from carbon sinks to carbon sources, new study finds
New research warns that Africa's forests, once vital allies in the fight against climate change, have turned from a carbon sink into a carbon source.
Dialog / Dislocations without crystals: Burgers vectors discovered in glass
For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, which move through ...
Phys.org / Earth's rapid warming 56 million years ago left plants struggling to keep up
Around 56 million years ago, Earth suddenly got much hotter. Over about 5,000 years, the amount of carbon in the atmosphere drastically increased and global temperatures shot up by some 6°C.
Phys.org / How have our satisfaction (and our productivity) with teleworking evolved since the COVID shock?
The COVID-19 pandemic accelerated the pace at which both employees and employers developed experience with telework. How has this changed employees' views on teleworking? Researchers at UGent@Work conducted a follow-up study ...
Phys.org / Humpback whales are making a comeback—here's one reason why
When University of Southern Denmark whale researcher Olga Filatova set off on her first field trip in 2000, she spent five years looking for whales before she saw a humpback.
Tech Xplore / Artificial tendons give muscle-powered robots a boost
Our muscles are nature's actuators. The sinewy tissue is what generates the forces that make our bodies move. In recent years, engineers have used real muscle tissue to actuate "biohybrid robots" made from both living tissue ...
Phys.org / Researchers uncover synchronous ecological collapse across Paleotethys Ocean during Permian–Triassic transition
A research team from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS), in collaboration with international partners, has completed a high-resolution biomarker analysis of the Zal ...
Medical Xpress / Specialized neuron populations in the mouse cortex coordinate to guide correct decisions, study suggests
For decades, neuroscientists have been trying to pinpoint the neural underpinnings of behavior and decision-making. Past studies suggest that specialized groups of neurons in the mammalian brain, particularly in the cortex, ...
