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.

For microscopic organisms, ocean currents act as 'expressway' to deeper depths      (via sciencedaily.com)     Original source 

Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.

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.

Medical school scientist creates therapy to kill hypervirulent bacteria      (via sciencedaily.com)     Original source 

Researchers are on a mission to kill drug-resistant bacteria, and a new study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics.Researchers have shown that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It becomes a health hazard when it enters other parts of the body and can cause pneumonia, urinary tract and wound infections. Those at highest risk include seniors and patients with other health problems such as diabetes, cancer, kidney failure and liver disease.

Microneedles and suction cup for blood diagnostics, modeled on leeches      (via sciencedaily.com)     Original source 

A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at low cost, it is also suitable for developing countries.
