Chemists Make Playdough/Lego-Like Hybrid to Create Tiny Building Blocks

Sacanna2017HiRes.jpg

Playdough and Legos are among the most popular childhood building blocks. But what could you use if you wanted to create something really small—a structure less than the width of a human hair? It turns out, a team of chemists has found, this can be achieved by creating particles that have both playdough and Lego traits.

Biologist Reaches Into Electric Eel Tank, Comes Out with Equation to Measure Shocks

Vanderbilt University researcher Ken Catania stuck his arm into a tank with small electric eel 10 times -- the only way to get accurate measurements of the circuit created by animal, arm and water.

Hidden in plain sight – that’s how researchers describe their discovery of a new genus of large forest tree commonly found, yet previously scientifically unknown, in the tropical Andes. Researchers from the Smithsonian and Wake Forest University detailed their findings in a study just released the journal PhytoKeys.

The surprising results of a Northern Arizona University astronomer's new study find that there are 3.5 million house-sized meteoroids whose orbits bring them close enough to Earth to pose potential impact hazards—ten times fewer than previously thought.

Ocean Exploration Uncovers One of Cuba's Hidden Natural Treasures

After nearly two years of planning, a team of scientists from the U.S. and Cuba has explored never-before-studied mesophotic coral reefs along the entire coast of Cuba, spanning about 1,500 miles. Except for a few places along the coast, prior to this expedition, there were virtually no data or charts indicating what was beyond the shallow reef zone.

Researchers using Los Alamos’ unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done.

New Look at Archaic DNA Rewrites Human Evolution Story

Nucleositepattern_v2.png

A U-led team developed a method for analyzing DNA sequence data to reconstruct early history of archaic human populations, revealing an evolutionary story that contradicts conventional wisdom about modern humans, Neanderthals and Denisovans. The Neanderthal-Denisovan lineage nearly went extinct after separating from modern humans. Just 300 generations later, Neanderthals and Denisovans diverged around 744,000 years ago. The global Neanderthal population grew to tens of thousands of individuals living in fragmented, isolated populations.
