Scientists investigating the remains of an old wooden ship off the cold, windy coast of far southern Argentina say it almost certainly is the Dolphin, a globe-trotting whaling ship from Warren, R.I., lost in 1859. Archaeologists have spent years researching the ship's origin without making a definitive identification, but a...
Sahelanthropus, the oldest representative of humanity, was indeed bipedal…but that’s not all!
The modalities and date of emergence of bipedalism remain bitterly debated, in particular because of a small number of very old human fossils. Sahelanthropus tchadensis, discovered in 2001 in Chad, is considered to be the oldest representative of the humankind. The shape of its cranium suggests a bipedal station. The...
Plants That Pull Nitrogen From Thin Air Thrive in Arid Environments
After a comprehensive study of plants across the United States, researchers have arrived at the unexpected conclusion that plants able to fix atmospheric nitrogen are most diverse in arid regions of the country.
Machine Learning Algorithm Predicts How to Get the Most Out of Electric Vehicle Batteries
The researchers, from the University of Cambridge, say their algorithm could help drivers, manufacturers and businesses get the most out of the batteries that power electric vehicles by suggesting routes and driving patterns that minimise battery degradation and charging times.
Pheasant Meat Sold for Food Found to Contain Many Tiny Shards of Toxic Lead
A study has found that pheasants killed by lead shot contain many fragments of lead too small to detect by eye or touch, and too distant from the shot to be removed without throwing away a large proportion of otherwise useable meat.
Nitrous oxide emissions from Corn Belt soils spike when soils freeze, thaw
Nitrous oxide may be much less abundant in the atmosphere than carbon dioxide, but as a greenhouse gas, it's a doozy. With a potency 300 times greater than CO2, nitrous oxide's warming potential, especially via agriculture, demands attention. Researchers are now answering the call. In a new study, they document...
Biologists track DNA ‘parasites’ in the hunt for disease treatments
Biologists offer new insights into entities known as transposons, providing knowledge that could one day help in the fight against cancers and aging-related diseases.
Study Finds That Ocean Cooling Over Millennia Led to Larger Fish
Earth’s geological history is characterized by many dynamic climate shifts that are often associated with large changes in temperature.
Ocean cooling over millennia led to larger fish
To investigate whether paleoclimatic temperature shifts are correlated with body size changes, biologists decided to test this hypothesis using tetraodontiform fishes as a model group.
Scientists evaluate Earth-cooling strategies with geoengineering simulations
A group of international scientists is rigorously and systematically evaluating if and how the stratosphere could be made just a little bit 'brighter,' reflecting more incoming sunlight so that an ever-warming Earth maintains its cool.
