Osteoarthritis is a debilitating condition that affects at least 27 million people in the United States, and at least 12 percent of osteoarthritis cases stem from earlier injuries. Over-the-counter painkillers, such as anti-inflammatory drugs, help reduce pain but do not stop unrelenting cartilage destruction. Consequently, pain related to the condition only gets worse.
Now, researchers at Washington University School of Medicine in St. Louis have shown that they can inject nanoparticles into injured joints in mice and suppress inflammation immediately following an injury, reducing the destruction of cartilage.
The findings are reported online Sept. 26 in the early edition of the Proceedings of the National Academy of Sciences.

Lmao.
Scientists working in Ecuador have discovered a new species of ant in the most unusual of places – the vomit of a bright orange ‘devil frog’ known as the diablito.
So far, we don’t know much about the new tropical ant, which hae elongated mouthparts (possibly to help catch food), and has been given the formal name Lenomyrmex hoelldobleri, in tribute to German biologist and ant expert Bert Hölldobler.

Out of all the pressures we face in our everyday lives, there’s no denying that the nature of time has the most profound effect. As our days, weeks, months, and years go by, time moves from past to present to future, and never the other way around.
But according to the physics that govern our Universe, the same things will occur regardless of what direction time is travelling in. And now physicists suggest that gravity isn’t strong enough to force every object in the Universe into a forward-moving direction anyway.
So does time as we know it actually exist, or is it all in our heads? First off, let’s run through a little refresher about the so-called arrow of time.

Why do we remember the past, but not the future? It seems like a silly question, but for some scientists, it’s a deep mystery wrapped up in physics and perception.
The mystery takes another twist in a study appearing in the same journal that published Albert Einstein’s theories of relativity more than a century ago.
