Sun's activity influences natural climate change
For the first time, a research team has been able to reconstruct the solar activity at the end of the last ice age, around 20,000-10,000 years ago, by analysing trace elements in ice cores in Greenland and cave formations ...
Recycling old batteries into solar cells
This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries—a potential source of lead pollution—into new, long-lasting solar panels ...
Emerging solar plants scorch birds in mid-air
A new form of solar energy is having an unwanted side effect: It makes some birds ignite in midair.
Solar power, origami-style
(Phys.org) —As a high school student at a study program in Japan, Brian Trease would fold wrappers from fast-food cheeseburgers into cranes. He loved discovering different origami techniques in library ...
Towards more efficient solar cells
A layer of silicon nanocrystals and erbium ions may help solar cells to extract more energy from the ultraviolet (UV, high-energy) part of the solar spectrum. Experimental physicists from the FOM Foundation, ...
Eco-friendly 'pre-fab nanoparticles' could revolutionize nano manufacturing
A team of materials chemists, polymer scientists, device physicists and others at the University of Massachusetts Amherst today report a breakthrough technique for controlling molecular assembly of nanoparticles ...
Study offers insights into a new class of semiconducting materials
A new paper by University of Notre Dame researchers describes their investigations of the fundamental optical properties of a new class of semiconducting materials known as organic-inorganic "hybrid" perovskites.
Follow the radio waves to exomoons, astrophysicists say
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists ...
Sun sets for a NASA solar monitoring spacecraft
After 14 years of monitoring Earth's main energy source, radiation from the sun, NASA's Active Cavity Radiometer Irradiance Monitor satellite has lost contact with its ground operations team at NASA's Jet ...
Dating the sun's prenatal history can help find life on other planets
Without the sun, there would be no Earth – but amazingly, we don't know the finer details about the prenatal history of our sun, where it was born and if other stars in our galaxy share a similar history.
Electromagnetic disaster could cost trillions and affect millions. We need to be prepared
Predicting or worrying about disasters is a popular pastime. But we tend to take notice when somebody with money at stake becomes concerned.
Satellite system makes eagle spotting a doddle in Scotland
Monitoring natural resources, biodiversity and wildlife data is crucial for economic and ecological sustainability. But in areas that are hard to reach, monitoring becomes a problem. In Scotland, for example ...
Violent solar system history uncovered by WA meteorite
Curtin University planetary scientists have shed some light on the bombardment history of our solar system by studying a unique volcanic meteorite recovered in Western Australia.
Rosetta will teach us more about comets than we have learned in 50 years
On August 6, millions of miles away from Earth, the firing of a rocket thruster signalled the end of a decade-long journey by a European spacecraft to reach its ultimate target – a comet.
