The oldest and fastest evolving moss in the world might not survive climate change      (via sciencedaily.com)     Original source 

A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

A new weapon in the war on robocall scams      (via sciencedaily.com) 

The latest weapon in the war on robocalls is an automated system that analyzes the content of unsolicited bulk calls to shed light on both the scope of the problem and the type of scams being perpetuated by robocalls. The tool, called SnorCall, is designed to help regulators, phone carriers and other stakeholders better understand and monitor robocall trends -- and take action against related criminal activity.

Potential novel breakthrough treatment for fungal infections      (via sciencedaily.com)     Original source 

Fungal infections are killing thousands of Americans each year, some with a morbidity rate of nearly 80%. To make matters worse, only a handful of antifungal treatments are available, and even those are becoming less effective as fungi become more resistant. However, researchers recently published findings indicating that a novel breakthrough treatment may have been discovered.

Smart devices: Putting a premium on peace of mind      (via sciencedaily.com) 

The White House has announced plans to roll out voluntary labeling for internet-connected devices like thermostats and baby monitors that meet certain cybersecurity standards. A new survey of U.S. consumers shows that they are willing to pay a significant premium to tell which gadgets are safe from security attacks before they buy. But voluntary product labels may not be enough if the program is going to protect consumers in the long run, the findings suggest.

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.

Dry days trigger leaves to send a surprising growth signal telling roots to keep growing      (via sciencedaily.com)     Original source 

Scientists have discovered a new molecular signalling pathway, triggered when leaves are exposed to low humidity, that ensures plant roots keep growing towards water. A new study has found that when the leaves of a plant are exposed to dry air (low humidity), they send a shoot-to-root signal, using abscisic acid (ABA), to tell the roots to keep growing. This is a surprising finding as ABA is usually thought to be a growth inhibitor, not a growth promoter.

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.

'Shoebox' satellites help scientists understand trees and global warming      (via sciencedaily.com)     Original source 

As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.

How will a warming world impact the Earth's ability to offset our carbon emissions?      (via sciencedaily.com)     Original source 

New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
