Principles of Chromatin Looping
Human chromosome condensed in cell nucleus can stretch out up to 2 meter. The complex convolution of chromosome and its winding/unwinding mechanism is nothing short of amazing. Despite our technological advancement, we still don't know the exact mechanism of chromosome looping. Study published in Cell has developed first 3D map of the human genome. Scientists claim that mapping of genome will help us understand the organization of genome within time and space along with studying activation and inactivation of genome in real time.

Bullet proof Nanofibers

Kevlar is currently the material of choice to make bullet proof vests but it may get replace by new nanofibers which can absorb more energy than kevlar and can stretch 7 times of it's original length. The inspiration for the material comes from bone collagen spiral structure and it is composed of spinning polyvinylidene fluoride (PVDF) and polyvinvylidene fluoride trifluoroethylene (PVDF-TrFE).

"When stretched, these polymer-based yarns create an electrical charge which acts to attracts the polymer back in on itself — an attraction found to be 10 times stronger than a hydrogen bond. (Hydrogen bonds are considered some of the strongest inter-molecular forces we know of.) The result is a material that can absorbs terrific amount of energy before it fails. "

What Smoking Does to an unborn baby?
Smoking kills, slowly but surely, but it can potentially change whole life of unborn kid. Ultrasound 4D scans show delayed development of central nervous system in fetus born to smoking moms. How does that affects child life in long term is still a open question.
"After studying their scans at 24, 28, 32 and 36 weeks, foetuses whose mothers smoked continued to show significantly higher rates of mouth movement and self-touching than those carried by non-smokers."

Cellular scissors chop up HIV virus

When a copy of the HIV virus sneaks into a human cell, it uses the cell's own molecular machinery to make copies of the virus's genetic material and then buries these copies in the cell's own genes. From there, the host's cell becomes an HIV factory, making new copies of the virus to spread throughout the body. Existing HIV drugs target individual lifecycle steps like stopping the virus from integrating into cells' DNA, or trying to stop the affected cells from producing more virus. But these drugs have to be taken all their lives as the HIV copies can remain dormant for years and then activate again.Salk scientists have gotten one step closer to creating such a drug by customizing a powerful defense system used by many bacteria and training this scissor-like machinery to recognize the HIV virus and eliminating the HIV copies completely from the genome for ever.

What makes us 3 Dimensional?

Ever wondered why human body is symmetrical or all our organs are 3 dimensional? What determines our body structures and it dimensions ? Obvious answer will be it is all in genes and environment but which gene? Scientist have identified first regulator of our 3D body, YAP.

" YAP played a role in tissues' tensile strength, which is why they looked at it in the first place. But they couldn’t experiment on human organs, so they mutated the YAP gene in an embryo of a medaka fish, or Japanese rice fish, to see how it would react to gravity without it. They found that the embryos with the YAP mutation were significantly flatter in the direction of gravity and the tissues didn’t align themselves in the right way--most notably the tissues in the lens of the eye."

These findings can really help us understand tissue and organ formation and help us engineer more robust human tissues and organs.

Graphene - Amazing despite being "Defective"

Since it's discovery Graphene has been considered "wonder material" with potential to change technology like never before due to its pristine 2D structure. Now scientists have discovered that defective graphene can acts as highly efficient membrane for proton transfer in fuel cells.
"by knocking out at least four carbon atoms from the normally pristine structure, it performed vastly better. A large number of protons (and nothing else) slipped through imperfections in the atom-thick material in just a few seconds, efficiently generating electricity."
