Toxic elements found in stranded whales, dolphins over 15 years

Toxic elements found in stranded whales, dolphins over 15 years

Whales and dolphins get their nutrients and essential elements through their diet. While eating fish, squid, octopus, crustaceans and other marine mammals, they are also exposed to heavy metal contaminants. Elevated levels of toxins have been found in stranded dolphins and whales along the Southeastern Coast of the United States. Monitoring toxic contaminants in these … Read more

Tailoring morphology symmetry of bismuth vanadate photocatalysts for efficient charge separation

Tailoring morphology symmetry of bismuth vanadate photocatalysts for efficient charge separation

Tailoring morphology symmetry of BiVO4 photocatalyst from octahedral to truncated octahedral crystals leads to the quite different separation of photogenerated charges and a significantly improved charge separation efficiency. The built-in electric field for driving photogenerated charge separation is considered to be modulated by tuning the morphology symmetry. Credit: Science China Press In a study published … Read more

An awkward family reunion: Sea monsters are our cousins

Toxic elements found in stranded whales, dolphins over 15 years

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study from the Stowers Institute for Medical Research discovered that the hindbrain — the part of the brain controlling vital functions like blood pressure and heart rate — of both sea lampreys and humans … Read more

Credit: Pixabay/CC0 Public Domain Lockdown drills, practiced to help prepare children for shooting incidents at school, make those who have been exposed to violence feel safer, a new study of thousands of students in the US indicates. The finding, reported in a paper published in the Journal of School Violence, contradicts claims that the drills … Read more

Does Russia stand to benefit from climate change?

Toxic elements found in stranded whales, dolphins over 15 years

“There’s a narrative out there about climate change that says there are winners and losers. Even if most of the planet might lose from the changing climate, certain industries and countries stand to benefit. And Russia is usually at the tip of people’s tongues, with Russian officials even making the claim that Russia is a … Read more

US returns to lunar surface for first time in over 50 years: ‘Welcome to the moon’ | Space

US returns to lunar surface for first time in over 50 years: ‘Welcome to the moon’ | Space

The United States has returned to the lunar surface for the first time in more than 50 years after a privately-built spacecraft named Odysseus capped a nail-biting 73-minute descent from orbit with a touchdown near the moon’s south pole. Amid celebrations of what Nasa hailed “a giant leap forward”, there was no immediate confirmation of … Read more
