Rapid 3D analysis of rockfalls in Yosemite
Yosemite National Park contains some of the world's most iconic landforms, including Half Dome, Yosemite Falls, and El Capitan. Although the cliffs of Yosemite...
Tricky feat with stand-up molecule
For quite a while now, researchers have been able to produce structures from single atoms. One of the first examples was presented by D....
I am human, hear me roar: Judging formidability from human vocalizations
Many animals -- including sea lions, red deer, and dogs -- use vocalizations to judge one another's size and physical formidability when in competition...
Biologists show that female seals have consistent personalities
Female seals don't change their spots, according to a new study by University of Alberta biologists. In fact, individual differences in boldness remain consistent...
Administering hormones affects DNA
The public debate on endocrine disrupting chemicals (EDCs) -- exogenous substances that have the same or similar effects as endogenous hormones -- has been...
Timing is key for bacteria surviving antibiotics
For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that...
Mars valleys traced back to precipitation
The surface of Mars bears imprints of structures that resemble fluvial steam networks on Earth. Scientists therefore assume that there must have been once...
Astronomers observe the magnetic field of the remains of supernova 1987A
For the first time, astronomers have directly observed the magnetism in one of astronomy's most studied objects: the remains of Supernova 1987A (SN 1987A),...
Quantum gas reveals first signs of path-bending monopole
Magnets, whether in the form of a bar, horseshoe or electromagnet, always have two poles. If you break a magnet in half, you'll end...
Researchers observe unique chiral magnetic phenomenon
Tiny magnetic vortex structures, so-called skyrmions, have been researched intensively for some time for future energy-efficient space-saving data storage devices. Scientists at Forschungszentrum Jülich...
The odds of living to 110-plus level out — once you hit 105
Want to be a supercentenarian? The chances of reaching the ripe old age of 110 are within reach -- if you survive the perilous...
