Future Cities May be Built of bones instead of pollution-causing Concrete, Steel

Future Cities May be Built of bones instead of pollution-causing Concrete, Steel

If a team of researchers from the University of Cambridge has its way, artificial bones and eggshells would replace pollution-causing concrete and steel as building material for the rapid expansion in urban areas. They claim it would be the most environment-friendly method to accommodate the growing population in cities.

The researchers claim that concrete and steel together account for about 10% of the world's total greenhouse gas emissions.

Comet-scented perfume smells like ‘rotten eggs, cat urine and bitter almonds’

Comet-scented perfume smells like ‘rotten eggs, cat urine and bitter almonds’

Jacob Aron from New Scientist has reported that a new perfume has appealed to the space lover composed of the aromatic scents of a comet. Perfumologists from a British company ‘The Aroma Company’ specialized in what it dubs ‘scent marketing technology’ have made a perfume formed on comet 67P/Churyumov–Gerasimenko.

First Magnetar Found With Wind Nebula Around

First Magnetar Found With Wind Nebula Around

In a first of its kind discovery, astronomers have found a wind nebula surrounding a magnetar, which is an exceptional ultra-magnetic neutron star. Wind nebula is an enormous cloud comprising of high-energy particles. Magnetars are the most powerful magnets in the universe and this discovery offers an exclusive opportunity to understand the characteristics, environment and outbreak history of magnetars.

NASA satellite makes first observation of single methane leak on Earth

NASA satellite makes first observation of single methane leak on Earth

Everyone talks about the dangers of increasing carbon dioxide in environment, but methane is a source of greenhouse gas posing greater level of danger to climate than CO2, but it is often neglected because of its less availability in the atmosphere.

There are sources that can contribute to increase in methane, leaving us fighting the battle with another greenhouse gas to sustain life on this planet. This will delight everybody to know that we already have a way to measure methane release available.

What caused Greenland's Ice Melt? Scientists Have an Explanation

What caused Greenland's Ice Melt? Scientists Have an Explanation

Apart from soaring temperature and tropical weather, there’s another phenomenon behind the ice melt of Greenland, and its Arctic amplification, suggested a new study. Scientists noticed that sea ice in the Arctic had a record low extent in May this year.

Mount St. Helens Volcano could erupt in future, but not anytime soon

St. Helens Volcano is likely to prepare for eruption, but not anytime soon

The Pacific Northwest Seismic Network has detected more than 130 small intensity earthquakes under Mount St. Helens since March 14. The low-magnitude earthquakes suggest scientists that they are activating Mount St. Helens volcano for another eruption. There may have been more earthquakes, but were minor enough to be non-detectable. The rate of earthquakes has been increasing gradually, and reached to almost 40 quakes per week.

How Solar System was Formed and Evolved? Tailless Comet Could Provide an Answer

How Solar System was Formed and Evolved? Tailless Comet Could Provide an Answer

A tailless comet has been discovered by astronomers with the help of Pan-STARRS telescope. Named C/2014 S3, the first-of-its-kind tailless comet thought to have been knocking around the space since our solar system was formed.

The unique space object holds clues about the formation and evolution of the solar system, as per a new study on the comet published in the journal Science Advances. The comet is an ancient body that may have returned from the edge of the solar system.

Mount Paektu Volcano could erupt in future as seismologists notice signs of heightened activity

Mount Paektu Volcano could erupt in future as seismologists notice signs of heightened activity

According to an international group of scientists studying the volcanic area in China and North Korea, the volcano can possibly erupt in the coming time as seismologists have observed a few signs of heightened activity.

Mount Paektu, considered as a sacred mountain by North Koreans, has spanned over a wider area between China and North Korea. The study team includes seismologists from China, North Korea, the United States and the United Kingdom. It suggested that the volcano is very active, but presently its time of eruption can’t be estimated specifically.

Octopuses change color to show aggression and other social behaviors: study

Octopuses resolve fights using color to mark their mood: study

Octopuses are social animals that change their body colors to show aggressiveness and intimidate their neighbors, a video footage of a group of the sea creatures in Jervis Bay revealed.

The previously unknown behavior of octopuses was recorded by a local diver and the study co-author, Matthew Lawrence. It immediately drew the attention of octopus experts, including University of Sydney’s Prof. Peter Godfrey-Smith and Alaska Pacific University’s Professor David Scheel.

Quasar SDSS J1011+5442 astonishes astronomers with its fast changing data

Quasar SDSS J1011+5442 astonishes astronomers with its fast changing data

Astronomers were surprised to notice that a quite quasar named SDSS J1011+5442 changed dramatically over the last 12 years. First noticed in 2003, quasar SDSS J1011+5442 has possibly eaten out its own fill in the recent years. The research team from University of Washington used the spectrum measurements of the quasar to calculate various factors. The reading for year 2015 suggests that the hydrogen-alpha emission declined by a factor of 50.
