The spread of humans around the world from Africa thousands of years ago wiped out big mammals in a shrinking trend that could make the cow the biggest mammal on Earth in a few centuries` time, a scientific study said on Thursday.Apr 20, 2018, 11:16 AM IST
Scientists have developed an artificial intelligence that can recognise a person's face even in the dark, a development that could lead to enhanced real-time biometrics and post-mission forensic analysis for covert nighttime operations.Apr 17, 2018, 17:53 PM IST
Our limited understanding of dark matter and energy may be making us blind to signals from intelligent alien life, which possibly exist in dimensions that humans cannot perceive.Apr 11, 2018, 17:41 PM IST
Nearly 13,000-year footprints — likely of two adults and a child — found on an island off western Canada.Mar 29, 2018, 13:11 PM IST
The robots named as hydraulically amplified self-healing electrostatic (HASEL) actuators eschew the bulky, rigid pistons and motors of conventional robots with soft and electrically activated structures.
The robots have been manufactured by coating tiny algae with magnetic particles and can smoothly swim in biological fluids.
After excavating three new sites in southern Spain, over more than 10 years, the researchers discovered evidence of distinct Neanderthal materials dating from 37,000 years ago.
The findings enhance our understanding of how animals can communicate using body posture across the species barrier and are specifically helpful for informing horse handlers and trainers about the ways horses perceive human body language.Nov 05, 2017, 14:10 PM IST
The study found evidence that people may have been eating the popular fruit as many as 15,000 years before they domesticated the fruit as an agricultural crop.
When the ancestors of modern humans migrated out of Africa, they passed through the Middle East and Turkey before heading deeper into Asia and Europe.
A study suggests that the early development of more complex mating systems may at least partly explain why anatomically modern humans thrived while other species, such as Neanderthals, did not.Oct 07, 2017, 12:07 PM IST
NASA will land humans on the Moon and establish presence on the lunar surface before sending astronauts to the Red Planet, US Vice President Mike Pence has said.Oct 06, 2017, 13:30 PM IST
Swedish and South African scientists managed to identify the genetic sequence of the remains of three hunter-gatherer individuals who lived between 2,300 and 1,800 years ago and four peasants who lived between 500 and 300 years agoSep 29, 2017, 16:34 PM IST
Researchers performed behavioural experiments to test birds and humans and found that the cause of the slight multitasking advantage in birds is their higher neuronal density.Sep 27, 2017, 19:47 PM IST
Using a stem cell technique for sperm creation, scientists have created healthy offspring from genetically infertile male mice, offering a potential new approach to tackling a common genetic cause of human infertility.Aug 18, 2017, 23:23 PM IST
Amphibians, reptiles, mammals - all of them communicate via acoustic signals.Jul 27, 2017, 13:45 PM IST
Learning new songs is a form of what is known as 'social learning', where individual animals learn behaviours from each other rather than having them passed on from one generation to another genetically.Jul 26, 2017, 00:23 AM IST
Researchers, including those from the University of Georgia (UGA) in the US, found that by 2015, humans had generated 8.3 billion metric tonnes of plastics, 6.3 billion tonnes of which had already become waste.Jul 21, 2017, 13:59 PM IST
The site was last excavated nearly 30 years ago by a group of archaeologists, who suggested that the site was between 50,000 and 60,000 years old, considered to be one of the first human settlements in Australia.Jul 20, 2017, 16:25 PM IST
Researchers from Lund University in Sweden let ravens solve tasks that they do not encounter in the wild, and hence lack specific adaptations for: tool use, and bartering with humans.Jul 16, 2017, 16:55 PM IST
