Physicist Create a Fluid With Negative Mass

Physicists from Washington State university have created a liquid with negative mass meaning that when you push it, instead of accelerating in that direction, it accelerates backwards.

Matter can have a negative mass much the same way that particles can be negatively charged. Newton’s second law of motion (F=ma) tells us that mass will accelerate in the direction of the force so we can deduce that matter with a negative mass would do the opposite.

To create the conditions for negative mass, Peter Engels and his team started by cooling rubidium atoms to a Bose-Einstein condensate meaning they reached very near absolute 0. The researchers used lasers to trap the atoms in an area less than 100 microns across and allow high energy particles to escape cooling them further. Then to create negative mass, the physicists applied a second set of lasers to change the way atoms spin back and forth. They then removed the first set of lasers causing the rubidium to rush out and then appear to hit some sort of invisible wall; behaving as if it had a negative mass.

What’s great about this is the control we have over the negative mass without any other complications. This gives us a new tool we can use to engineer experiments in astrophysics looking at neutron stars, black holes, dark energy and a lot more.

Here’s the paper: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.118.155301. Very interesting, I look forward to seeing the results replicated.

The Lilium Jet – The world's first all-electric VTOL jet

The Lilium Jet successfully completed its maiden test flight series in the skies above Bavaria. The 2-seater Eagle prototype executed a range of complex maneuvers, including its signature mid-air transition from hover mode to wing-borne forward flight.

The March for Science is the first step of a global movement to defend the vital role science plays in our health, safety, economies, and governments.

It's time to get off the sidelines and make a difference.

The March for Science champions robustly funded and publicly communicated science as a pillar of human freedom and prosperity. We unite as a diverse, nonpartisan group to call for science that upholds the common good and for political leaders and policy makers to enact evidence based policies in the public interest.

The March for Science is a celebration of science. It's not only about scientists and politicians; it is about the very real role that science plays in each of our lives and the need to respect and encourage research that gives us insight into the world.

Nevertheless, the march has generated a great deal of conversation around whether or not scientists should involve themselves in politics. In the face of an alarming trend toward discrediting scientific consensus and restricting scientific discovery, we might ask instead: can we afford not to speak out in its defense?

There is no Planet B. Join the #MarchForScience.

Backchat: April 2017

Science fans everywhere will take to the streets this weekend in the March for Science. Plus, biases in artificial intelligence and how scientific papers are getting harder to read.

We Just Breached the 410 Parts Per Million Threshold | Climate Central

The world just passed another round-numbered climate milestone. Scientists predicted it would happen this year and lo and behold, it has.

On Tuesday, the Mauna Loa Observatory recorded its first-ever carbon dioxide reading in excess of 410 parts per million (it was 410.28 ppm in case you want the full deal). Carbon dioxide hasn’t reached that height in millions of years. It’s a new atmosphere that humanity will have to contend with, one that’s trapping more heat and causing the climate to change at a quickening rate.

Podcast: When good lions go bad, listening to meteor crashes, and how humans learn to change the world

This week, meteors’ hiss may come from radio waves, pigeons that build on the wings of those that came before, and a potential answer to the century-old mystery of what turned two lions into people eaters with Online News Editor David Grimm. Elise Amel joins Julia Rosen to discuss the role of evolution and psychology in humans’ ability to overcome norms and change the world, as part of a special issue on conservation this week in Science. Listen to previous podcasts. [Image: bjdlzx/iStockphoto; Music: Jeffrey Cook]
