Australian study proves "humans are planet"s most frightening predator"
Australia lacks fearsome large carnivores like lions and wolves, and the relative lack of fear that marsupials like kangaroos and wallabies show to dogs (and other introduced carnivores) has been attributed to a lack of evolutionary experience with l.....»»
First comprehensive characterization of the extraordinary thermoelectric properties of cadmium arsenide thin films
If there's one thing we humans are good at, it's producing heat: significant amounts, and in many cases most of the energy we generate and put into our systems we lose as heat, whether it be our appliances, our transportation, our factories, even our.....»»
The worm has turned: DIY lab platform evaluates new molecules in minutes
Plants are powerhouses of molecular manufacturing. Over the eons, they have evolved to produce a plethora of small molecules—some are beneficial and valuable to humans, while others can be deadly. For years, a good way for scientists looking for ne.....»»

Three new extinct walnut species discovered in high Arctic mummified forest
In a new study, scientists describe three new, but long-extinct, walnut species on an island above the Arctic Circle. The fossils were discovered further north than any known walnut species, living or extinct, and represent some of the oldest-known r.....»»
New study investigates the reconstruction of the intertropical convergence zone
The study focuses on the so-called Intertropical Convergence Zone (ITCZ), a low-pressure trough near the equator whose position and intensity changes seasonally with the position of the sun. Trade winds from the northern and southern hemispheres meet.....»»
Teaching biology—no more stressing out over structural formulas
Structural formulas are a source of dread for many students, but they're an essential tool in biology lessons. A joint study has shown that the stress levels of students working with chemical formulas are significantly reduced if they are given simpl.....»»
Study projects loss of brown macroalgae and seagrasses with global environmental change
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and.....»»
