Elliptical elegance in glittering host of galaxies

Whereas ESO’s Very Large Telescope (VLT) can observe very faint astronomical objects in great detail, when astronomers want to understand how the huge variety of galaxies come into being they must turn to a different sort of telescope with a much bigger field of view. The VLT Survey Telescope (VST) ... Read More »

Those fragrances you enjoy? Dinosaurs liked them first

The compounds behind the perfumes and colognes you enjoy have been eliciting olfactory excitement since dinosaurs walked the Earth amid the first appearance of flowering plants, new research reveals. Oregon State University entomologist George Poinar Jr. and his son Greg, a fragrance collector, found evidence that floral scents originated in ... Read More »

Iron-silica particles unlock part of the mystery of Earth’s oxygenation

The oxygenation of Earth’s atmosphere was thanks, in part, to iron and silica particles in ancient seawater, according to a new study by geomicrobiologists at the University of Alberta. But these results solve only part of this ancient mystery. Early organisms called cyanobacteria produced oxygen through oxygenic photosynthesis, resulting in ... Read More »

Key aspects of human cell aging reversed by new compounds

Key aspects of the ageing of human cells can be reversed by new compounds developed at the University of Exeter, research shows. In a laboratory study of endothelial cells — which line the inside of blood vessels — researchers tested compounds designed to target mitochondria (the “power stations” of cells). ... Read More »

Largest haul of extrasolar planets

Forty-four planets in solar systems beyond our own have been unveiled in one go, dwarfing the usual number of confirmations from extrasolar surveys, which is typically a dozen or less. The findings will improve our models of solar systems and may help researchers investigate exoplanet atmospheres. Novel techniques developed to ... Read More »

Link between appendicitis and allergies discovered

Children with allergies have a lower risk of developing complicated appendicitis, according to a new study from Lund University and Skåne University Hospital in Sweden. The findings, now published in JAMA Pediatrics, could pave the way for new diagnostic tools in the future. “In a study of all the children ... Read More »

Created line of spinal cord neural stem cells shows diverse promise

Researchers at University of California San Diego School of Medicine report that they have successfully created spinal cord neural stem cells (NSCs) from human pluripotent stem cells (hPSCs) that differentiate into a diverse population of cells capable of dispersing throughout the spinal cord and can be maintained for long periods ...

Earth at risk of heading towards ‘hothouse Earth’ state

Keeping global warming to within 1.5-2°C may be more difficult than previously assessed, according to researchers. An international team of scientists has published a study in Proceedings of the National Academy of Sciences (PNAS) showing that even if the carbon emission reductions called for in the Paris Agreement are met, ...

Navigation satellite INRSS-1I put into orbit, ISRO calls it a success

SRIHARIKOTA: The Indian Space Research Organisation’s navigation satellite INRSS-1I was on Thursday launched by PSLV-C41 from the spaceport in Sriharikota and successfully placed in the designated orbit. PSLV-C41/IRNSS-1I Mission blasted off at 4.04 am from the first launchpad at the Sathish Dhawan Space Centre. ISRO officials called it a normal ... Read More »

Why Nasa is going two million kilometres to mine an asteroid

NEW DELHI: Asteroids are known to be treasure troves of precious minerals. A Nasa mission is under way to test the feasibility on a nearby asteroid, and a niche group of companies is ramping up to claim a piece of the pie. Nasa’s Osiris-Rex, launched from Cape Canaveral in Florida in 2016, has travelled ... Read More »

Mars is the only solution for the survival of humanity

New Delhi: After British physicist, Stephen Hawking – known for being quite vocal about his thoughts on alien encounters with humans – a theoretical physicist and futurist Michio Kaku has passionately argued that our future lies in the stars – literally. In his new book called ‘The Future of Humanity’, ... Read More »
