Researcher uncovers evidence of earliest known dairy production in India

In the fertile river valley along the border of modern-day India and Pakistan, the Indus Valley Civilization built some of the largest cities in the ancient world. Feeding such a large population would have been a significant challenge. New research from Kalyan Sekhar Chakraborty reveals one of the ways the civilization was able to sustain so many people. The postdoctoral researcher at the University of Toronto Mississauga has shown that dairy was being produced as far back as 2500 BCE. It is the earliest known dairy production in India, and could have helped produce the type of food surplus needed for trade.

Researchers create a new 'green' engine for lorries

Researchers from the Polytechnic University of Valencia (UPV) have designed a new engine to decrease the environmental impact of the most common type of lorries that travel on European roads—those that weigh between 18 and 25 tons. From their laboratories at the CMT-Thermal Engines of the UPV, they propose a new configuration that unites all the benefits of hybrid and dual-fuel combustion engines.

High-confidence approach for artificial intelligence-based models

They call it artificial intelligence—not because the intelligence is somehow fake. It's real intelligence, but it's still made by humans. That means AI—a power tool that can add speed, efficiency, insight and accuracy to a researcher's work—has many limitations.
