Phys.org / Tides can be mapped much more locally using a new method based on satellite images
When high or low tide occurs, the water does not necessarily rise and fall uniformly along the entire coastline. In fact, the height of the tide in a bay can vary by up to one meter (3 feet) from one location to another just ...
Phys.org / The length of your online reviews may help scammers map your friends and target them
On the surface, posting online reviews looks like a win-win activity. It helps both businesses we like and people who might frequent them. But although posting reviews can benefit others, it can also put us all at risk, according ...
Phys.org / Centuries of child labor left lasting spinal damage in Dutch children, study finds
Children in the postmedieval Dutch workforce worked so hard that their spines became worn and deformed, with some children affected before they even had a chance to lose their baby teeth, a new study published in the International ...
Phys.org / How plastic welds retain a molecular 'memory' of their former surfaces to strengthen pipe joints
Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene ...
Phys.org / A never-before-seen picture of eagle migrations
In 1899, scientists began tracking avian migration by placing a small ring with an identifier around birds' ankles. Researchers then had to recapture the birds elsewhere, leaving the journey between those points a mystery. ...
Phys.org / Airborne tuberculosis bacteria may mutate as they dry, revealing a target to curb drug resistance
Tuberculosis bacteria released into the air from infected individuals dry out to form infectious particles that are second only to measles in contagiousness. Weill Cornell Medicine investigators have discovered specific mechanisms ...
Phys.org / Nano-sandwich photocathode improves solar conversion of CO₂ into ethanol
Czech researchers at Charles University in Prague, led by Pavla Eliášová, have developed an advanced photocathode that helps convert the greenhouse gas carbon dioxide into pure ethanol using sunlight. The new technology solves ...
Phys.org / How everyday household tasks impact relationships
The physical, cognitive and emotional loads of running a household should be recognized when examining the health of a couple's relationship, new research has found. A University of Queensland study examined the "tri-load" ...
Phys.org / Takeaway cups may be releasing microplastics into your coffee
Single-use paper cups used for takeout coffee and other beverages release millions of microplastic particles when exposed to hot liquid, University of Queensland researchers have found.
Phys.org / Engineered bacteria offer a new way to accelerate rock weathering for carbon removal
Rock weathering, the breakdown and dissolving of rocks and minerals caused by their exposure to water, air and biological life, is a major regulator of Earth's atmospheric CO2 levels and climate. Throughout Earth's history, ...
Phys.org / Light reveals internal motion in electron crystals and can trigger their melting
Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting ...
Phys.org / Why some earthquakes caused by fracking come with warning signs
Fracking, the injection of high-pressure fluid to fracture rock and release oil or gas, can trigger earthquakes. While some sites generate small tremors beforehand that may provide an early warning, others produce few or ...
