Why computer security advice is more confusing than it should be      (via sciencedaily.com) 

If you find the computer security guidelines you get at work confusing and not very useful, you're not alone. A new study highlights a key problem with how these guidelines are created, and outlines simple steps that would improve them -- and probably make your computer safer.

Genetic secrets of America's favorite snack      (via sciencedaily.com)     Original source 

In its simplest form, popcorn is pretty uncomplicated. Most supermarket varieties offer the choice of two kernel colors, yellow or white, and two kernel shapes, pointed or pearl. When popped, the flake typically expands into one of two shapes: mushroom or butterfly. But there's more to popcorn than meets the eye. New research reveals a wealth of untapped diversity lurking in popcorn's genetic code.

Researchers develop digital test to directly measure HIV viral load      (via sciencedaily.com)     Original source 

A milliliter of blood contains about 15 individual drops. For a person with human immunodeficiency virus (HIV), each drop of blood could contain anywhere from fewer than 20 copies of the virus to more than 500,000 copies. Called the viral load, this is what is measured to allow clinicians to understand how patients are responding to anti-viral medications and monitor potential progression. The time-consuming viral load testing needs to be repeated several times as a patient undergoes treatment. Now, a research team has developed a time and cost-efficient digital assay that can directly measure the presence of HIV in single drop of blood.

How coral reefs can survive climate change      (via sciencedaily.com)     Original source 

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.

Extinct warbler's genome sequenced from museum specimens      (via sciencedaily.com)     Original source 

The Bachman's warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according a new study in which the full genomes of seven museum specimens of the bird were sequenced.

Drug decelerates bacterial race to antibiotic resistance      (via sciencedaily.com)     Original source 

Researchers report that, in laboratory cultures and animal models, a drug significantly reduces the ability of bacteria to develop antibiotic resistance, which might prolong antibiotic effectiveness.

Researcher uses pressure to understand RNA dynamics      (via sciencedaily.com)     Original source 

Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn. Scientists are studying the conformational landscapes of biomolecules and how they modulate cell function. When biomolecules receive certain inputs, it can cause the atoms to rearrange and the biomolecule to change shape. This change in shape affects their function in cells, so understanding conformational dynamics is critical for drug development.

A roadmap for gene regulation in plants      (via sciencedaily.com)     Original source 

For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.

Now, every biologist can use machine learning      (via sciencedaily.com)     Original source 

Scientists have built a new, comprehensive AutoML platform designed for biologists with little to no ML experience. New automated machine learning platform enables easy, all-in-one analysis, design, and interpretation of biological sequences with minimal coding. Their platform, called BioAutoMATED, can use sequences of nucleic acids, peptides, or glycans as input data, and its performance is comparable to other AutoML platforms while requiring minimal user input.

Completing genome of rusty patched bumble bee may offer new approach to saving endangered bee      (via sciencedaily.com)     Original source 

A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.
