Scientists achieve more than 98% efficiency removing nanoplastics from water      (via sciencedaily.com)     Original source 

Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.

Pit-building venom mixers      (via sciencedaily.com)     Original source 

Researchers show that the adaptation of antlions to their ecological niche has also changed their venom. They compared the venom system of antlion and closely related green lacewing larvae. Antlions produce a much more complex venom from three different venom glands than lacewing larvae do. All the venom proteins identified come from the insects themselves, not from symbiotic bacteria. Some of the toxins are new and appear to be unique to antlions. Waiting for their victims in pitfall traps in the sand, antlions can use their venom to immobilize larger prey. The venom therefore plays an important ecological role in adapting to their barren habitat.

Researchers ID body's 'quality control' regulator for protein folding      (via sciencedaily.com)     Original source 

Anyone who's tried to neatly gather a fitted sheet can tell you: folding is hard. Get it wrong with your laundry and the result can be a crumpled, wrinkled mess of fabric, but when folding fails among the approximately 7,000 proteins with an origami-like complexity that regulate essential cellular functions, the result can lead to one of a multitude of serious diseases ranging from emphysema and cystic fibrosis to Alzheimer's disease. Fortunately, our bodies have a quality-control system that identifies misfolded proteins and marks them either for additional folding work or destruction, but how, exactly, this quality-control process functions is not entirely known. Researchers have now made a major leap forward in our understanding of how this quality-control system works by discovering the 'hot spot' where all the action takes place.

Taking a 'one in a million' shot to tackle dopamine-linked brain disorders      (via sciencedaily.com)     Original source 

With the help of a tiny, transparent worm called Caenorhabditis elegans, researchers have identified novel players in dopamine signaling by taking advantage of a powerful platform generated via the Million Mutation Project (MMP) for the rapid identification of mutant genes based on their functional impact. They can seek insights from simpler organisms whose genes bear striking similarity to those found in humans and where opportunities for genetic insights to disease can be pursued more efficiently and inexpensively.

An appetizer can stimulate immune cells' appetite, a boon for cancer treatments      (via sciencedaily.com)     Original source 

The body has a veritable army constantly on guard to keep us safe from microscopic threats from infections to cancer. Chief among this force is the macrophage, a white blood cell that surveils tissues and consumes pathogens, debris, dead cells, and cancer. Macrophages have a delicate task. It's crucial that they ignore healthy cells while on patrol, otherwise they could trigger an autoimmune response while performing their duties.

Machine learning approach helps researchers design better gene-delivery vehicles for gene therapy      (via sciencedaily.com)     Original source 

Gene therapy could potentially cure genetic diseases but it remains a challenge to package and deliver new genes to specific cells safely and effectively. Existing methods of engineering one of the most commonly used gene-delivery vehicles, adeno-associated viruses (AAV), are often slow and inefficient. Now, researchers have developed a machine-learning approach that promises to speed up AAV engineering for gene therapy. The tool helps researchers engineer the protein shells of AAVs, called capsids, to have multiple desirable traits, such as the ability to deliver cargo to a specific organ but not others or to work in multiple species. Other methods only look for capsids that have one trait at a time.
