Molecular troublemakers instead of antibiotics?
They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists are researching how it can be possible to prevent the formation of biofilms from the beginning. On this basis, alternatives to antibiotics could be developed, as many pathogens are already resistant.

Novel 'repair system' discovered in algae may yield new tools for biotechnology
The algae C. reinhardtii uses a novel system for releasing an interrupting sequence from a protein -- a technique that may be useful for protein purification.

Highly sensitive and effective tool measures how your cells grow and divide
An improved sequencing tool reveals dynamic changes of poly(A) tails in eggs and embryos. By revealing the dynamic poly(A) regulation during the translation of RNA into protein, the study furthered our understanding as to how the fabric of life is shaped: from the color of your skin to your hair to how tall you will grow.

Fast-growth cyanobacteria have allure for biofuel, chemical production
While relentless bright light brings many forms of cyanobacteria to their knees -- figuratively, of course -- Synechococcus sp. PCC 7002 does the opposite, thriving and growing at a rate that far outpaces most of its peers. Now researchers know why: it triples in size to accommodate a rapid expansion of the cellular machinery it uses to build proteins.

New Leishmania virulence strategies
Medical researchers have discovered novel virulence strategies employed by the Leishmania parasite. These scientific breakthroughs represent two important clues to understanding the cellular and molecular mechanisms governing the parasitic infections that cause leishmaniasis, a neglected tropical disease endemic in one hundred countries.

Scientists discover how certain proteins may help fight chlamydia
Scientists have made an interesting discovery, which may help fight chlamydia infection -- one of the most widespread STDs in the world. A series of experiments have shown that certain proteins are capable of killing harmful bacteria cells by shutting down their stress response system.

How animals keep their cells identical
A regulatory protein named ERI-1 helps ensure that all cells in a tissue remain identical to one another, a research team has discovered for the first time. The work involved an unusual collaboration between developmental biologists and linguists, with the latter contributing their expertise with machine learning software. The finding could bring biologists one step closer to understanding some cancers and other age-related diseases.

To divide or not: A cellular feedback loop enables new cells to make a fateful decision
New research sheds light on a critical decision every newly born cell makes: whether to continue to proliferate or exit the cell-division cycle. In cancer, the equivalent of an 'on' switch is stuck in that position. In healthy cells, the team has discovered, the opposing effects of proteins ORC1 and CDC6 in controlling the level of Cyclin E contributes to the stability of the genome.

Plasma technology can be tapped to kill biofilms on perishable fruit, foods
Seeing fruit 'turn bad and going to waste' inspired a team of researchers in China to explore using atmospheric pressure nonequilibrium plasma as a novel solution to extend the shelf life of fruit and other perishable foods. Now their computational study of how air plasma interacts with bacterial biofilms on an apple's surface suggests that plasma technology could be used to decontaminate food in the future.

Parasite proteins prompt immune system to fight off ovarian tumors in mice
Scientists identified the specific proteins secreted by the parasite Toxoplasma gondii that cause the immune system in mice to attack established ovarian tumors.
