If you walk along the Oudezijds Achterburgwal canal in Amsterdam, you will notice an elegant and aesthetically pleasing steel bridge for pedestrians. If not for the media attention it got, you would even consider it a regular feature of the city’s architecture. But this bridge loaded with sensors, is actually the world’s first 3D-printed steel bridge, according to an Imperial College London press release.

“A 3D-printed metal structure large and strong enough to handle pedestrian traffic has never been constructed before,” said Imperial co-contributor Prof. Leroy Gardner of the Department of Civil and Environmental Engineering, in a press release. “We have tested and simulated the structure and its components throughout the printing process and upon its completion, and it’s fantastic to see it finally open to the public.”

Technology and medicine are becoming more wondrous, and now a new drug will be developed that will prevent people from freezing.

The Butterfly Nebula is really “a tempestuous fire-sneezing dragon, with eyes that project ultraviolet light,” according to astronomer Bruce Balick.

A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children.

A chronic cough is more than just an annoyance. A chronic cough can interrupt your sleep and leave you feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness and even rib fractures.

While it can sometimes be difficult to pinpoint the problem that’s triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.

We use logic to build facts into systems of thought, but paradoxes force us to question what we think we know. And it could be worse, because logic may not be sufficient to comprehend reality.

The rebooting came in the form of a gene therapy involving three genes that instruct cells to reprogram themselves—in the case of the mice, the instructions guided the cells to restart the epigenetic changes that defined their identity as, for example, kidney and skin cells, two cell types that are prone to the effects of aging. These genes came from the suite of so-called Yamanaka stem cells factors—a set of four genes that Nobel scientist Shinya Yamanaka in 2006 discovered can turn back the clock on adult cells to their embryonic, stem cell state so they can start their development, or differentiation process, all over again. Sinclair didn’t want to completely erase the cells’ epigenetic history, just reboot it enough to reset the epigenetic instructions. Using three of the four factors turned back the clock about 57%, enough to make the mice youthful again.

“We’re not making stem cells, but turning back the clock so they can regain their identity,” says Sinclair. “I’ve been really surprised by how universally it works. We haven’t found a cell type yet that we can’t age forward and backward.”

Rejuvenating cells in mice is one thing, but will the process work in humans? That’s Sinclair’s next step, and his team is already testing the system in non-human primates. The researchers are attaching a biological switch that would allow them to turn the clock on and off by tying the activation of the reprogramming genes to an antibiotic, doxycycline. Giving the animals doxycycline would start reversing the clock, and stopping the drug would halt the process. Sinclair is currently lab-testing the system with human neurons, skin, and fibroblast cells, which contribute to connective tissue.

A team of researchers at the Korean Advanced Institute of Science (KAIST) has succeeded in developing a new artificial muscle using graphene-liquid crystal composite fibers.

The team, led by Professor Kim Sang-ouk of the Department of Materials Science and Engineering, stressed that the artificial muscle was found to be the most similar to human muscle among those reported to the scientific community so far.

Also, the artificial muscle showed up to 17 times stronger strength when compared to human muscles.
