Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine.
Daily measurements of CO2 at the authoritative "Keeling lab" on Hawaii have topped 400 parts per million for the first time. The station, which sits atop the Mauna Loa volcano, has the longest continuous measure of the concentration of the gas, stretching back to 1958.
The Big Bang is somewhat of a mystery to scientists. They have long wondered why during this critical point in our Universe's history, more matter than antimatter was created. Now, they've discovered a clue that may eventually provide the answer to that question. Researchers have found the first direct evidence of pear-shaped nuclei in exotic atoms.
Researchers developed a portable way to produce ultracold atoms for quantum technology and quantum information processing, a scientific breakthrough that was published and featured on the front cover of Nature Nanotechnology.
Light and sound waves can be passed around objects, making them invisible since there is no shadow behind the object, by means of special meta-materials. Karlsruhe Institute of Technology researchers, who previously developed the world's first three-dimensional invisibility cloak for visible light, now succeeded in demonstrating that these special materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon was shown to conduct heat around a central area without the edge being affected.
A 105-year-old Texas woman has earned a place in almost all headlines by revealing the most unlikely secret to her long life.
It's a bit like probiotics for mosquitoes. When scientists infect mosquitoes with a specific bacterium, the insects become resistant to the malaria parasite.
TRADITIONALLY, ARCHAEOLOGY HAS involved a lot of digging through both archives and dirt, as well as being in the right place at the right time. But the last decade has seen the development of a completely new tool, says Dr David Thomas, a pioneer of the field of satellite archaeology.
At his office in Cairo's Zamalek district, Ahmed Eissa, Egypt's newly-appointed minister of state for antiquities, sits before a huge wooden desk, reviewing papers and welcoming well-wishers.
"My goal is to work with ministry employees to preserve and protect Egypt's heritage – be it ancient Egyptian, Greco-Roman, Coptic or Islamic – while putting existing archaeological works in order, rejuvenating projects that have been put on hold, and upgrading the skills of archaeologists and curators," Eissa said.
The Arctic experienced an extended period of warm temperatures about 3.6 million years ago — before the onset of the ice ages — at a time when the concentration of carbon dioxide in Earth's atmosphere was not much higher than the levels being recorded today, a new study finds. The research suggests that an ice-free Arctic may be a reality in the near future.
More than a year after the Deepwater Horizon disaster, crude oil continued to sicken Gulf Coast fish, according to a new study. Gulf killifish, which are considered sentinel species that can indicate broader environmental problems, suffered heart defects, delayed hatching and other problems.
Starting in the 1980s, Alaska's Columbia Glacier began retreating, shrinking from 41 miles long (its originally documented length in 1794) to 36 miles long in 1995. This is what that change actually looks like from space.
Researchers have solved the riddle of how one of Africa's greatest civilisations survived a catastrophic drought which wiped out other famous dynasties. Geomorphologists and dating specialists from The Universities of Aberystwyth, Manchester, and Adelaide say that it was the River Nile which made life viable for the renowned Kerma kingdom, in what is now northern Sudan.
Kerma was the first Bronze Age kingdom in Africa outside Egypt.
It is a city shrouded in myth, swallowed by the Mediterranean Sea and buried in sand and mud for more than 1,200 years. But now archeologists are unearthing the mysteries of Heracleion, uncovering amazingly well-preserved artifacts that tell the story of a vibrant classical-era port.
In Manshiet Dahshur, 25 miles south of Cairo, the villagers recently extended the boundaries of the cemetery. For Ahmed Rageb, a carpenter who buried his cousin in the annexe, it was a logical decision. "We want to bury the dead," he said, strolling through the new cemetery after visiting his cousin's tomb. "The old cemetery is full. And there is no other place to bury my family.".
When it comes to dinosaurs and other prehistoric monsters, even the experts can get things wrong — as dino-fanatic Brian Switek explains in his tour guide to the paleontological frontier.
The righting of wrongness begins with the title of Switek's book: "My Beloved Brontosaurus: On the Road With Old Bones, New Science and Our Favorite Dinosaurs." As most 9-year-olds could probably tell you, there's officially no such thing as a Brontosaurus. That name for the quintessential long-tailed, long-necked sauropod went out of fashion when scientists figured out that the Jurassic giant had already been dubbed Apatosaurus.
Researchers have announced fossils dating back to about 10 million years after the mass extinction of the dinosaurs suggest a line of animals considered the biological predecessors of the dinosaurs lived in what are now the African countries of Tanzania and Zambia many millions of years before and after the great die-off.
The research is included in a paper appearing this week in the Proceedings of the National Academy of Sciences.
Many scientists have thought that dinosaur predecessors missed the race to fill habitats emptied when nine out of 10 species disappeared during the Earth's largest mass extinction, approximately 252 million years ago. The thinking was based on fossil records from sites in South Africa and southwest Russia. It turns out that scientists may have been looking for the starting line in the wrong places.
They lived in well-planned cities, made exquisite jewelry, and enjoyed the ancient world's best plumbing. But the people of the sophisticated Indus civilization—which flourished four millennia ago in what is now Pakistan and western India—remain tantalizingly mysterious.
Unable to decipher the Indus script, archaeologists have pored over beads, slivers of pottery, and other artifacts for insights into one of the world's first city-building cultures.
Researchers from the University of Gothenburg, Sweden, have spent many years studying the remains of a Stone Age community in Karleby outside the town of Falköping, Sweden. The researchers have for example tried to identify parts of the inhabitants' diet. Right now they are looking for evidence that fertilisers were used already during the Scandinavian Stone Age, and the results of their first analyses may be exactly what they are looking for.
