Exercise and chronic pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

While the overall premise of exercise is clear, the details of how often, what kind and the best approach for recovery after exercising are rather less. The problem for people with chronic pain is that moving HURTS. Some people have even argued that chronic pain is, in essence, an activity intolerance disorder... Read more »

Eyeless Fish Navigates with Mouth Suction

by Elizabeth Preston in Inkfish

As bats squeak and swoop through pitch-black Mexican caves, the pale fish that inhabit the pools below them perform a soundless imitation. These fish are blind but sense the world through subtle pressure changes on their skin. To navigate the cave floors, they also use a tool that’s never been observed in another animal: the […]The post Eyeless Fish Navigates with Mouth Suction appeared first on Inkfish.... Read more »

How to Incorporate Elusive Atoms into Nanodiamond

by Shannon Demlow in Blingtronics - Science, Engineering and Diamonds

In an article published last week in Nature Communications [1], Andrew Magyar and coworkers described a method for getting europium with a particular electronic structure into diamond. Before we examine the how let's look for a second at the why, as in, "why would you want to put europium into nanodiamond?"... Read more »

Don't stress out your testicles!

by Brooke LaFlamme in Molecular Love (and other facts of life)

You probably don’t need science to tell you that when you’re stressed out you’re not likely to be in the mood. But can stress cause physical damage to your reproductive cells? A study published this month in the Journal of Sexual Medicine suggests that it just might.... Read more »

And nature does it in real-time

by Paul Stevenson in Blog of the Isotopes

A paper of mine appeared today in Physical Review E.  Called, "Extension of the continuum time-dependent Hartree-Fock method to proton states1."  As the name suggests, it is a paper about methodology - so it's not going to feature in any press-releases about exciting new physics results.  It's even an extension to an existing method (from our previous paper), which might make it seem all the less exciting.  I think it's still a good paper, and a useful one, hence the blo........

Major breakthrough in stem cell manufacturing technology

by beredim in Stem Cells Freak

Kevin ShakesheffCreditCell therapy is an exciting and rapidly developing area of medicine in which stem cells have the potential to repair human tissue and maintain organ function in chronic disease and age-related illnesses. But a major problem with translating current successful research into actual products and treatments is how to mass-produce such a complex living material.There are two distinct phases in the production of stem cell products; proliferation (making enough cells to form large........

Dutch Men are not Nordic Men

by Rense Nieuwenhuis in Curving Normality

There are reasons to appreciate Hanna Rosin’s ‘The End of Men’: it was pleasantly written, contains various entertaining anecdotes, and holds an attractive promise of increased gender equality – although, to trumpet the demise of men (to paraphrase page 285) might be somewhat less desirable. It would have made for a relevant book, were it not that the facts are wrong.... Read more »

Why Money Doesn’t Buy Meaning

by Katharine Blackwell in Contemplating Cognition

Sometimes psychologists do try to tackle the big questions. We might not be willing (or equipped) to speculate about the true meaning of life, but we can try to determine what might lead more people in one nation to say “yes” to one simple question:

Do you feel your life has an important purpose or meaning?... Read more »
