Air pollution linked to 10 lakh stillbirths a year worldwide, including India: Study

Almost 10 lakh stillbirths a year can be attributed to air pollution, according to a global study published in the journal Nature Communications. It covered 137 countries including India, Pakistan, Nigeria, China and Bangladesh. Almost half of the stillbirths could be linked to exposure to pollution particles smaller than 2.5 microns (PM2.5), mostly produced from the burning of fossil fuels. readmore...


Scientists simulate a 'baby wormhole' using a quantum computer for 1st time

Scientists have developed a quantum experiment that allows them to study the behaviour of a special kind of theoretical wormhole for the first time. The experiment hasn't created an actual wormhole (a rupture in space and time), rather it allows probing connections between theoretical wormholes and quantum physics. It was a "baby wormhole," according to Caltech physicist Maria Spiropulu. readmore...


'World's oldest meal' found in a 550 million-year-old fossil; pic released

Scientists have found the contents of the last meal consumed by the earliest animals known to inhabit Earth more than 550 million years ago. Scientists from The Australian National University analysed a fossilised specimen of the slug-like Kimberella from the Ediacaran period. The team detected phytosterol molecules, a type of fat found in plants, preserved in the creature's gut. readmore...


Pic shows 'world's oldest fossilised brain' dating back half-a-billion years

A University of Arizona researcher has said the fossil of a tiny sea creature, which died over half-a-billion years ago, is "the oldest fossilised brain" ever found. The fossil of the wormlike animal Cardiodictyon catenulum was initially discovered in 1984. The creature's nervous system, including a brain, was preserved in the fossil measuring 1.5 cm. readmore...


NASA releases 'sound' of 'light echoes' coming from a black hole

American space agency NASA has released the soundtrack that it made through the sonification of X-ray data of 'light echoes' around a black hole. These 'light echoes' or blasts of light happen around black holes as the material surrounding them produces intense bursts of electromagnetic radiation, which travel outward. This particular track records 'light echoes' from V404 Cygni black hole. readmore...


Pic shows polar ice cap on Mars as the planet comes the closest to Earth

Astrophotographer Andrew McCarthy has captured a picture of Mars using a 14" telescope that shows the northern polar ice cap on the red planet. He took the picture at a time when Mars made its closest approach to Earth. Several people reacted to his photo, with one tweeting, "This is the best Earth-based image of Mars I've ever seen." readmore...


Pic shared by NASA shows Pluto's true colours

NASA shared an image taken by its New Horizons spacecraft at a distance of 22,025 miles (35,445 km), showing Pluto's true colours. It also shows the 'heart' of Pluto –glacier made of nitrogen and methane. Pluto's surface is coated in ice made of water, methane, and nitrogen and is believed to have a rocky core and possibly a deep ocean. readmore...


First images of Earth captured by Oceansat-3 released by ISRO

ISRO has released the first images of Earth captured by EOS-06 or Oceansat-3. The images cover the Himalayan region, Gujarat Kutch region and the Arabian Sea. They are captured by the Ocean Colour Monitor (OCM) and Sea Surface Temperature Monitor (SSTM) Sensors. ISRO launched Oceansat-3 along with eight nano-satellites on November 26. readmore...


48,500-year-old 'zombie' virus revived from Siberian permafrost

Seven types of viruses that have lain frozen in Siberian permafrost for thousands of years have been revived. The youngest were frozen for 27,000 years, while the oldest was on ice for 48,500 years, making it the most ancient virus resuscitated so far. Some of these “zombie viruses” could potentially be dangerous to humans, scientists who revived the viruses said. readmore...


NASA spacecraft takes pic showing both Earth and Moon in one frame

NASA's Orion spacecraft has taken a picture showing both Earth and the Moon in one frame. The picture was taken by the spacecraft after it covered its maximum distance from Earth of 2,68,563 miles. Orion has now travelled farther than any other spacecraft built for humans, beating even Apollo 13's record of 2,48,655 miles from 1970. readmore...


2 minerals never seen before on Earth found in 15-tonne meteorite

A 15-tonne meteorite that fell to Earth contains two minerals never seen before on our planet, scientists have said. Scientists at the University of Alberta in Canada said that the meteorite was found in rural Somalia two years ago. The official names for the new minerals are elaliite and elkinstantonite. readmore...


What is the nearly 50,000-yr-old 'zombie virus' revived by scientists recently?

Thirteen ancient viruses frozen in Siberian permafrost (permanently frozen ground) were recently revived by French scientists. These are called 'zombie viruses' as they have remained dormant since the prehistoric times. The oldest of these viruses is a 48,500-year-old amoeba virus named Pandoravirus yedoma, which was found at the bottom of a lake in Yakutia, Russia. readmore...


ISRO launches Earth Observation Satellite, 8 other nano satellites

ISRO on Saturday launched Earth Observation Satellite-06 (EOS-06) and eight other nano satellites on a PSLV-C54 rocket from the spaceport of Sriharikota. EOS-06, the primary payload of the rocket, would be separated in Orbit-1, while the eight other nano satellites would be placed in different orbits based on the customer requirements. readmore...


Mummies with golden tongues discovered in Egypt; pics surface

The Egyptian archaeological mission has discovered several ancient tombs containing mummies with golden tongues. The mummies were found in the ancient cemetery of Qewaisna about 40 miles north of Cairo, dating between 300BC and 640AD. Experts said the excavations inside the cemetery revealed that it was used during three different time periods. readmore...


China launches 3 astronauts to its newly completed space station

China on Tuesday launched a rocket carrying three astronauts to its newly completed space station. Upon reaching the Tiangong space station, the Shenzhou-15 astronauts will briefly share it with three astronauts from an earlier mission. China, barred by the US from participating in the International Space Station, is the only country to operate an orbiting station of its own. readmore...


NASA's Ingenuity helicopter performs its shortest flight on Mars

NASA's Ingenuity helicopter performed its shortest-ever flight on November 22, the first after a major software update. The helicopter's Flight 34 was even shorter than its first flight. It lasted only 18 seconds and saw the helicopter briefly hover after takeoff above Mars' surface before landing just 16 feet away from its starting point. readmore...
