Kent State University at Stark research unravels mysteries of mouthparts of butterflies
Matthew S. Lehnert, assistant professor of biological sciences at Kent State University at Stark, has been studying how the mouthparts of butterflies and moths work since 2010. His research shows that the method in which flies and butterflies ingest liquids into their own bodies for nourishment may be used as a model for delivering disease-fighting drugs to the human body. Drug delivery systems are engineered technologies for the targeted delivery and/or controlled release of therapeutic agents.

Study discovers fundamental unit of cell size in bacteria
By applying mathematical models to a large number of experiments in which bacterial growth is inhibited, a team of physicists, biologists and bioengineers from UC San Diego developed a 'general growth law' that explains the relationship between the average cell size of bacteria and how fast they grow.

Nanopores could map small changes in DNA that signal big shifts in cancer
Detecting cancer early, just as changes are beginning in DNA, could enhance diagnosis and treatment as well as further our understanding of the disease. A new study by University of Illinois researchers describes a method to detect, count and map tiny additions to DNA called methylations, which can be a warning sign of cancer, with unprecedented resolution.

Tool for checking complex computer architectures reveals flaws in emerging design
With backing from some of the largest technology companies, a major project called RISC-V seeks to facilitate open-source design for computer chips, offering the possibility of opening chip designs beyond the few firms that currently dominate the space. As the project moves toward a formal release, researchers at Princeton University have discovered a series of errors in the RISC-V instruction specification that now are leading to changes in the new system.

Researchers find mushrooms may hold clues to effect of carbon dioxide on lawns
Since the Industrial Revolution, the amount of carbon dioxide in the atmosphere has rapidly increased. Researchers at the University of New Hampshire set out to determine how rising carbon dioxide concentrations and different climates may alter vegetation like forests, croplands, and 40 million acres of American lawns. They found that the clues may lie in an unexpected source, mushrooms.

Treatment reverses signs of 2 degenerative brain diseases, ALS and ataxia, in mice
Scientists report a significant step toward combatting two degenerative brain diseases that chip away at an individual's ability to move, and think. A targeted therapy developed by investigators at University of Utah Health slows the progression of a condition in mice that mimics a rare disease called ataxia. In a parallel collaborative study led by researchers at Stanford University, a nearly identical treatment improves the health of mice that model Amyotrophic Lateral Sclerosis (ALS), commonly called Lou Gehrig's disease.

CWRU researchers discover 3 new species of extinct South American marsupials
The discovery of three extinct species and new insights to a fourth indicates a little-known family of marsupials, the Palaeothentidae, was diverse and existed over a wide range of South America as recent as 13 million years ago. Fossils of the new species were found at Quebrada Honda, a high elevation fossil site in southern Bolivia, and are among the youngest known palaeothentid fossils.

Physicists discover hidden aspects of electrodynamics
Radio waves, microwaves and even light itself are all made of electric and magnetic fields. The classical theory of electromagnetism was completed in the 1860s by James Clerk Maxwell. At the time, Maxwell's theory was revolutionary, and provided a unified framework to understand electricity, magnetism and optics. Now, new research led by LSU Department of Physics & Astronomy Assistant Professor Ivan Agullo, with colleagues from the Universidad de Valencia, Spain, advances knowledge of this theory. Their recent discoveries have been published in Physical Review Letters.

Wiring of the 'little brain' linked to multiple forms of mental illness
Nearly half of people with one mental illness also experience another mental illness at the same time. This is leading researchers to shift their focus away from individual disorders and search instead for common mechanisms or risk factors that might cause all types of mental disorders. Duke researchers have now linked specific differences in the cerebellum and pons to many types of mental illness.

Who are you on social media? New research examines norms of online personas
According to the Pew Research center, the majority of adults on the internet have more than one social networking profile on sites like Facebook, Twitter, and LinkedIn. Although the core purpose of these sites are similar -- to digitally connect with peers and loved ones -- new research conducted by researchers in Penn State's College of Information Sciences and Technology and King's College in London, England, found users often adopt different personas unique to each social network.

If you were monitoring a security camera and saw someone set down a backpack and walk away, you might pay special attention -- especially if you had been alerted to watch that particular person. According to Cornell University researchers, this might be a job robots could do better than humans, by communicating at the speed of light and sharing images.
