Tech Xplore / Industrial TOPCon solar cells hit 26.66% efficiency record
Crystalline silicon solar cells currently dominate the global photovoltaic industry, with tunnel oxide passivating contact (TOPCon) technology—a type of architecture within this product segment—rapidly gaining market ...
Phys.org / Climate change could fragment habitat for monarch butterflies, disrupting mass migration
Suitable habitat for migrating monarch butterflies will shift southwards because of climate change, according to a study published in PLOS Climate by Francisco Botello and Carolina Ureta at the National Autonomous University ...
Medical Xpress / Cell signaling step sharpens understanding of how the body responds to exercise's energy demands
Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this ...
Phys.org / Combination of wildfires and seismic lines may limit spread of non-native plants in Canada's boreal forest
A pair of disturbances common in Western Canada's boreal forests, when combined, may have an unexpected benefit of limiting the spread of non-native plant species, a University of Alberta study shows. The research gauged ...
Tech Xplore / Water-based enzyme ink enables one-step printing of wearable biofuel cells
Enzymatic biofuel cells can act as self-powered wearable biosensors by converting chemicals in body fluids into electricity; however, manufacturing challenges have prevented their widespread adoption. Now, researchers from ...
Phys.org / Iron and blue LEDs synthesize natural molecules, cutting the need for expensive chiral components
Photocatalysts facilitate chemical reactions by absorbing light. Metal-based photocatalysts are widely used in organic synthesis due to their durability and the ability to tune their function by modifying the ligands attached ...
Medical Xpress / Civilians face increasing harm from deadly explosive weapons, 17-country study finds
A University of Queensland study has found that almost 90% of people killed and injured by landmines and similar weapons are civilians. Dr. Stacey Pizzino from UQ's School of Public Health, together with her research team, ...
Medical Xpress / In Rett syndrome, leaky brain blood vessels traced to microRNA
MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them ...
Medical Xpress / Yawns in healthy fetuses might indicate mild distress
Even in the womb, where all oxygen is provided by the parental placenta, fetuses can—and do—yawn. More yawns during observation were associated with a lower weight at birth—potentially indicating mild fetal stress in ...
Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
Phys.org / Quantum effect could power the next generation of battery-free devices
A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster, and more efficient energy-harvesting ...
Phys.org / Viruses reveal shared way to kill bacteria by jamming small transporter MurJ
Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria ...
