President Trump says he came to Washington to “drain the swamp,” and now his administration is looking for wasteful programs to cut. A great start would be pulling the plug on numerous federal “research” programs that, frankly, have been captured by Washington special interests.
In fact, much of taxpayer-funded research serves ideological agendas—especially environmental activism—at the expensive of legitimate scientific inquiry. Consider a few examples.
By using lasers to manipulate a superfluid gas known as a Bose-Einstein condensate, the team was able to coax the condensate into a quantum phase of matter that has a rigid structure — like a solid, and can flow without viscosity, a key characteristic of a superfluid. Basically, they have created a supersolid, a
new form of matter which combines the properties of solids with those of superfluids.
Isn't that a contradiction?
“It is counterintuitive to have a material which combines superfluidity and solidity,” says team leader Wolfgang Ketterle, the John D. MacArthur Professor of Physics at MIT. “If your coffee was superfluid and you stirred it, it would continue to spin around forever.”
Metabolism, the set of processes through which we gain energy from food and produce the biomolecules we need in our body's cells, is universal to life. The biochemical pathways that underpin these processes are highly similar across all organisms and species.
The first day of the Neutrino Telescopes XVII conference in Venice is over, and I would like to point you to some short summaries that I published for the conference blog, at http://neutel11.wordpress.com.
- a summary of the talk on Super-Kamiokande
- a summary of the talk on SNO
- a summary of the talk on KamLAND
- a summary of the talk on K2K and T2K

You might have noticed that the above experiments were recipients of the 2016 Breakthrough prize in physics. In fact, the session was specifically focusing on these experiments for that reason.
Ethan Siegel has just written an article, "The Science Has Spoken: Pluto Will Never Be A Planet Again", so this is a response to it. I'll argue that far from "story over", actually we could make a discovery tomorrow that would turn the whole thing on its head and make their definition untenable. This will become particularly acute if we ever find a gas giant in the outer reaches of our solar system, too far away to clear its orbit. And we could find such a planet.
Elementary particles are mysterious and unfathomable, and it takes giant accelerators and incredibly complex devices to study them. In the last 100 years we have made great strides in the investigations of the properties of quarks, leptons, and vector bosons, but I would lie if I said we know half of what we would like to. In science, the opening of a door reveals others, closed by more complicated locks - and no clearer example of this is the investigation of subatomic matter.
To the outside world, muscles look like they contract or do work but at the very small scale it is
myosin molecules pulling actin filaments and myosin and actin are essentially nanomachines that convert the chemical energy of ATP hydrolysis - how cells in our muscles create energy - into mechanical work.
New electron cryomicroscopy images reveal unexpectedly large conformational changes in the myosin molecule during the pull and that may show how myosin generates force and create a paradigm for the construction of true nanomachines.
An expert witness is a person authorized by a judge to share professional opinions in a court of law about subjects in which the expert was found to be sufficiently knowledgeable and competent.
During criminal or civil litigation, the permission granted to expert witnesses to give their opinions about topics of interest (DNA, fingerprints, accounting, ballistics, engineering, toxicology, and so forth) gives them considerable power and influence in the courtroom as compared to other kinds of witnesses.
Anyone announcing the successful sale of tourist trips around the moon would attract ridicule and laughter. Unless your name is Elon Musk. In that case the announcement amounts to nothing more than a logical and rather modest step towards Musk's promise of getting a million people to live on Mars.
If you’ve ever needed a blood transfusion, or donated blood, you probably would have been asked your blood type. While it was once thought all blood was the same, we now know there are different types of blood, called blood groups. Transfusions between blood groups can be catastrophic, even deadly, so knowing the blood type of donors and recipients is of the utmost importance.
Our bodies contain trillions of red blood cells. Each is covered in an array of proteins and sugars, inherited from our parents, which determine our blood group. We can all be classified into group A, B, AB or O, based on which sugars coat our red blood cells.
