Tech Xplore / Rechargeable Mg-O₂ battery uses metal-free nanoporous graphene cathode
Large-capacity rechargeable batteries capable of sustaining repeated charge-discharge cycles are expected to become core technologies for electric vehicles and other elements of an electrified society. However, current systems ...
Phys.org / Sustainability research overlooks key actors and actions in the face of the environmental crisis, says study
Efforts to advance toward a more sustainable world focus heavily on a limited set of actions and actors while overlooking key strategies and sectors needed to address the climate crisis and biodiversity loss, according to ...
Tech Xplore / New systems measures full magnetization hysteresis at MHz frequencies and high magnetic fields
High-frequency magnetic characteristics are essential for improving the efficiency, miniaturization, and operating frequency of power conversion devices such as power supply circuits, inductors, and transformers. However, ...
Medical Xpress / A blood marker could predict how people respond to antidepressants
Major depressive disorder (MDD) is among the most common psychiatric disorders, affecting approximately 330 people worldwide. This disorder is characterized by persistent feelings of sadness, hopelessness, low motivation, ...
Phys.org / Metasurface-based SLM could enhance AR, VR and LiDAR performance
Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include ...
Phys.org / Could Mars soil block Earth microbes? 'Water bears' offer a clue
Tardigrades, commonly known as water bears, may be better suited by a new name: Tardiguardians of the Galaxy. Unlike the fictional ragtag team of unenthusiastic heroes, the microscopic animals are providing real insight into ...
Phys.org / Political polarization can spur CO₂ emissions and stymie climate action
In recent years, studies and media reports have blamed growing partisan hostility in the U.S. for shattered marriages, broken families, ruined holiday dinners, and increased stress. New CU Boulder research suggests it may ...
Phys.org / Greenland's largest glacier could soon reach a tipping point, scientists say
Greenland's largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published ...
Medical Xpress / Women under 25 with cervical lesions face higher risk of heart disease, study finds
Young women with a history of cervical lesions are at 20% higher risk of developing cardiovascular disease and more likely to die from it, compared to others their age without the condition. High-grade squamous intraepithelial ...
Medical Xpress / Three-drug combo targets immune suppression to overcome melanoma resistance
For patients with advanced melanoma without BRAF mutation who no longer respond to immune checkpoint inhibitors, treatment options remain frustratingly limited. A new study from Vanderbilt researchers led by Professor Emerita ...
Phys.org / Using moon dirt with 3D printing to build future lunar colonies
Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers ...
Phys.org / The screech of peeling sticky tape conceals a rapid train of tiny shockwaves, ultrafast imaging shows
A new experiment has uncovered the mechanism responsible for the screeching sound made by peeling sticky tape. Using a combination of ultrafast imaging and synchronized acoustic recordings, Sigurdur Thoroddsen and colleagues ...
