Researchers have recently published FreeDTS -- a shared software package designed to model and study biological membranes at the mesoscale -- the scale 'in between' the larger macro level and smaller micro level. This software fills an important missing software among the available biomolecular modeling tools and enables modeling and understanding of many different biological processes involving the cellular membranes e.g. cell division.

Two of the Milky Way's earliest building blocks identified      (via sciencedaily.com)     Original source 

Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city.

Scientists find one of the most ancient stars that formed in another galaxy      (via sciencedaily.com)     Original source 

The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.

Robotic metamaterial: An endless domino effect      (via sciencedaily.com)     Original source 

If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.

Crawfish could transfer ionic lithium from their environment into food chain      (via sciencedaily.com)     Original source 

Lithium-ion rechargeable batteries are showing up in ever more devices, and the increasing use of this technology means more lithium is expected to find its way into the environment as a contaminant. In new research, a team has explored how this ion accumulates in a common Southern crustacean, the crawfish, with implications for the environment and public health.

Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.

Is food waste the key to sustainable, plastic-free diapers and sanitary pads?      (via sciencedaily.com)     Original source 

Once thrown away, disposable diapers and sanitary pads can take hundreds of years to decompose, because they contain plastics and other synthetic polymers. But now, researchers are replacing these materials with components made from protein biomass that is often discarded. They are sustainable and biodegradable, and they could potentially allow future diapers and pads to be flushed down a toilet or used as fertilizer.

Molecular crystal motors move like microbes when exposed to light      (via sciencedaily.com)     Original source 

At first glance, Rabih Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're made from crystallized molecules that perform coordinated movements when exposed to light. With continued development, these tiny machines could be used as drug-delivery robots or engineered into arrays that direct the flow of water around submarines.

Empty 'backpacks' activate the immune system against cancer      (via sciencedaily.com)     Original source 

Researchers have discovered that the mere act of attaching their microparticle 'backpacks' to neutrophils is enough to activate them against cancer -- no drugs needed. In experiments, backpack-bearing neutrophils shrank tumors and extended the survival of mice with cancer, and treated animals retained an immune memory of the disease. This approach opens the door to a new class of drug-free immunotherapy for cancer.
