Deglacial changes in western Atlantic Ocean circulation

Posted by in categories: chemistry, climatology, sustainability

A new study carried out by an international team of researchers, using the chemistry of ocean sediments has highlighted a widespread picture of Atlantic circulation changes associated with rapid climate change in the past.

The new integrated dataset, published today in the journal Nature Communications, provides new insights into the interactions of melting ice, and climate change, with potential implications for future long-term changes in the Earth systems with .

Dr. Hong Chin Ng from the University of Bristol’s School of Earth Sciences, is the study’s lead author.

Dr. Aubrey de Grey – SENS Research Foundation

Posted by in categories: biological, life extension, robotics/AI

It’s almost the weekend and what better way to celebrate than a nice long interview with one of the Heroes of aging research? Today we bring you a mega-interview with Dr. Aubrey de Grey.


Today we have an interview with Dr. Aubrey de Grey from the SENS Research Foundation. This interview conducted by Yuri Deigin was originally published in Russian language and he has kindly translated it into English so our audience can enjoy it too.

Yuri: Aubrey, thank you very much for agreeing to this interview. Why don’t we dive right in? I am sure everybody asks you this: how and when did you become interested in aging, and when did you decide to make it your life’s mission to defeat it?

Capture an asteroid, bring it back to Earth?

Posted by in category: space

BEIJING — Next time when your kids ask you to bring them a star from the sky, you don’t have to shrug and walk away. Tell them to wait, instead.

A group of Chinese scientists are mulling a bold idea to capture a small near-Earth asteroid, which might be a potential threat, and bring it back to Earth to exploit its resources.

“Sounds like science-fiction, but I believe it can be realized,” said Li Mingtao, a researcher at the National Space Science Center under the Chinese Academy of Sciences.

Star’s black hole encounter puts Einstein’s theory of gravity to the test

Posted by in categories: cosmology, physics

For more than 20 years, a team of astronomers has tracked a single star whipping around the supermassive black hole at the center of our galaxy at up to 25 million kilometers per hour, or 3% of the speed of light. Now, the team says the close encounter has put Albert Einstein’s theory of gravity to its most rigorous test yet for massive objects, with the light from the star stretched in a way not prescribed by Newtonian gravity. In a study announced today, the team says it has detected a distinctive indicator of Einstein’s general theory of relativity called “gravitational redshift,” in which the star’s light loses energy because of the black hole’s intense gravity.

“It’s really exciting. This is such an amazing observation,” says astronomer Andrea Ghez of the University of California, Los Angeles (UCLA), who heads a rival group that is also tracking the star. “This is a direct test [of relativity] that we’ve both been preparing for for years.”

The star, called S2, is unremarkable apart from a highly elliptical orbit that takes it within 20 billion kilometers, or 17 light-hours, of the Milky Way’s central black hole—closer than any other known star. A team led by Reinhard Genzel at the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching, Germany, has been tracking S2 since the 1990s, first with the European Southern Observatory’s (ESO’s) 3.6-meter New Technology Telescope in Chile’s Atacama Desert and later with ESO’s Very Large Telescope (VLT), made up of four 8-meter instruments. Ghez’s team at UCLA also began to observe the star around the same time with the twin 10-meter Keck telescopes in Hawaii.
