How differences in the genetic ‘instruction booklet’ between humans and Neanderthals influenced traits
When it comes to our differences from Neanderthals, most of what we know comes from comparing fossils. But fossils can only tell us about...
Researchers develop a compact infrared spectrometer
ETH researchers have developed a compact infrared spectrometer. It's small enough to fit on a computer chip but can still open up interesting possibilities—in...
The last mammoths died on a remote island
The last woolly mammoths lived on Wrangel Island in the Arctic Ocean; they died out 4,000 years ago within a very short time. An...
Rare ‘Lazarus superconductivity’ observed in promising, rediscovered material
Researchers from the University of Maryland, the National Institute of Standards and Technology (NIST), the National High Magnetic Field Laboratory (NHMFL) and the University...
Complex energies, quantum symmetries
In a certain sense, physics is the study of the universe's symmetries. Physicists strive to understand how systems and symmetries change under various transformations.
New...
Ancient Maya canals and fields show early and extensive impacts on tropical forests
New evidence in Belize shows the ancient Maya responded to population and environmental pressures by creating massive agricultural features in wetlands, potentially increasing atmospheric...
Early humans evolved in ecosystems unlike any found today
To understand the environmental pressures that shaped human evolution, scientists must first piece together the details of the ancient plant and animal communities that...
Voltage gated calcium channels ‘read’ electric patterns in embryos to create cartilage and bone
Scientists at Allen Discovery Center at Tufts University and Harvard Medical School have revealed how, in the case of limb formation, the electrical patterns...
Electrode-fitted microscope points to better designed devices that make fuel from sunlight
Using an atomic-force microscope fitted with an electrode tip 1,000 times smaller than a human hair, University of Oregon researchers have identified in real...
Pressure may be key to fighting climate change with thermoelectric generators
Pressure improves the ability of materials to turn heat into electricity and could potentially be used to create clean generators, according to new work...
Curiosity rover finds an ancient oasis on Mars
If you could travel back in time 3.5 billion years, what would Mars look like? The picture is evolving among scientists working with NASA's...
