Free-forming organelles help plants adapt to climate change      (via sciencedaily.com)     Original source 

Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers have now determined how these structures work on a molecular level, as well as where and how they form.

Genomes of 'star algae' shed light on origin of plants      (via sciencedaily.com)     Original source 

Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.

Human activity is causing toxic thallium to enter the Baltic sea, according to new study      (via sciencedaily.com)     Original source 

Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.

Promising new treatment strategy for deadly flu-related brain disorders      (via sciencedaily.com)     Original source 

Researchers have found that a brain disorder associated with flu (influenza-associated encephalopathy, or IAE) can be caused by the influenza virus entering the brain from the blood via endothelial cells. In these cells, the researchers observed viral protein accumulation, suggesting that antivirals targeting viral transcription/translation may be useful treatments for some patients. Given the lack of effective treatments for IAE, this finding will likely improve patient care and reduce IAE-related deaths worldwide.

Archaea can be picky parasites      (via sciencedaily.com)     Original source 

A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic microbes, so-called DPANN archea. Their study shows that these archaea are very 'picky eaters', which might drive their hosts to change the menu.
