A new ligand extends the half-life of peptide drugs from minutes to days
EPFL scientists have developed a ligand molecule that connects peptide drugs to blood-serum albumin and keeps them from being cleared out by the kidneys too soon. The ligand is easy to synthesize and can extend the half-life of therapeutic peptides from minutes to several days.

Invasive plant species can enhance coastal ecosystems
Invasive plant species like seaweed can provide vital ecosystem functions in coastal areas where native habitats such as salt marshes and oyster reefs have severely declined. A Duke study finds that invasive species could be used to offset the loss of native habitats that provide storm protection, food production and other benefits to billions of people.

Mountaintop coal mining causes Appalachian rivers to run 'consistently saltier'
Over time, alkaline salts and other contaminants from the coal residue and crushed rocks in valley fills leach into nearby streams and rivers, degrading water quality and causing dramatic increases in salinity that are harmful to downstream ecosystems.

Climate change could mean more weight restrictions and higher costs for airlines
As air temperatures rise at constant pressure, the density of air declines and this makes it harder for an airplane to take off. Increased air temperatures due to climate change could therefore present a new challenge for the aviation industry. This is according to Ethan Coffel of Columbia University in the US, lead author of a study in Climatic Change Letters which is a section in Springer's journal Climatic Change.

How social rank can trigger vulnerability to stress
EPFL scientists have identified rank in social hierarchies as a major determining factor for vulnerability to chronic stress. They also show that energy metabolism in the brain is a predictive biomarker for social status as well as stress vulnerability and resilience.

Researchers develop dynamic templates critical to printable electronics technology
When it comes to efficiency, sometimes it helps to look to Mother Nature for advice -- even in technology as advanced as printable, flexible electronics. Researchers at the University of Illinois have developed bio-inspired dynamic templates used to manufacture organic semiconductor materials that produce printable electronics. It uses a process similar to biomineralization -- the way that bones and teeth form. This technique is eco-friendly, which gives the researchers the chance to return the favor to nature.

NYU Tandon & NSF launch experiment to attract women & minorities to STEM entrepreneurship
The National Science Foundation (NSF) has awarded $500,000 to New York University's Tandon School of Engineering's Convergence of Innovation and Entrepreneurship (CIE) Institute to attract, instruct, and mentor student entrepreneurs -- particularly women -- in ways to use STEM (science, technology, engineering, and mathematics). Among the CIE's goals is to support diversity in STEM entrepreneurship, and to that end, teams with a desire to connect meaningful social change to innovation were encouraged to apply.

Slow earthquakes occur continuously in the Alaska-Aleutian subduction zone
Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that 'slow earthquakes' are occurring continuously, and could encourage damaging earthquakes. Slow earthquakes are quiet, can be as large as magnitude 7, and last days to years. Taking place mainly at the boundary between tectonic plates, they happen so slowly that people don't feel them.

Rice scientists simplify the incorporation of nitrogen into molecules
Rice University scientists generalize the synthesis of aminating agents to simplify the design and manufacture of drugs and other fine chemicals in which nitrogen atoms play key roles. Each of these agents contains an active electrophilic nitrogen atom to help chemists forge carbon-nitrogen bonds more easily than ever.

OU team details foreshock activities leading up to Pawnee earthquake
A University of Oklahoma geophysics professor, Xiaowei Chen, details the foreshock activities leading up to the Pawnee earthquake, and highlights the complicated relationship between seismicity and wastewater injection rates in a research study published this week in Scientific Reports. The study details the precursory earthquake (foreshock) sequences that culminated in the September 3, 2016, 5.8 magnitude earthquake near Pawnee, Okla., which ruptured along the previously unmapped Sooner Lake Fault.

How migrating birds 'run a marathon,' burning muscles and organs in long flights
Migrating birds complete long non-stop flights of many hours for songbirds and days for some shorebirds to reach breeding or wintering grounds. During such flights a bird's metabolic rate is very high, fueled by stored fat, but also by burning the protein in muscles and organs in a process that is not well understood, says eco-physiologist Alexander Gerson at UMass Amherst. He has a new grant to study the processes involved.

Using the stairs just got easier with energy-recycling steps
Researchers have created energy-recycling stairs that store a user's energy during descent and return energy to the user during ascent, making walking up and down stairs easier. When going up, the stairs give people a boost by releasing the stored energy, making it 37 percent easier on the knee than using conventional stairs.

Soft and stretchy fabric-based sensors for wearable robots
Wearable technologies are exploding in popularity, but most of the electronic sensors that detect and transmit data from wearables are made of hard, inflexible materials that can restrict both the wearer's natural movements and the accuracy of the data collected. Now, a team of researchers at the Wyss Institute and SEAS at Harvard University has created a highly sensitive soft sensor that leverages textiles in its construction, setting the stage for integration with fabric to make 'smart' robotic apparel.
