What is Disruptive Innovation?
Science News Journal
by SNJ
3y ago
The term ‘disruptive innovation’ has been around for more than two decades, and the best known example of this term is Uber. An app called HWY Pro has recently been launched for trucking companies to save owner-operators time and make the scheduling process more efficient. Bill Busbice, one of the founders of HWY Pro describes the app as “similar to, but very different from Uber.” Disruptive innovation was initially introduced as a powerful way of thinking about innovation-driven growth. Many leaders of small, entrepreneurial companies, as well as executives at large, well-established organiza ..read more

New X-Ray Technique Determines Molecular Structure
Science News Journal
by SNJ
3y ago
A new method that might improve the quality of X-ray images considerably when compared to current methods has been developed by scientists from Deutsches Elektronen-Synchrotron (DESY, Hamburg) and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU). The method is called incoherent diffractive imaging (IDI) and it could possibly be used to image individual atoms in molecules and nanocrystals faster with a much higher resolution. X-rays have been used for more than 100 years to help in determining the structure of molecules in crystallography. The foundation of the method are the principles ..read more

Scientists Are Putting Metrics for Measuring Schools and Teachers Under Scrutiny
Science News Journal
by SNJ
3y ago
A new study by a team of economists at MIT shows a new way of evaluating Value-Added Models (VAMs). VAMs are used to assess schools and teachers. Various states in the U.S. have recently started assessing schools and teachers using Value-Added Models, or VAMs. The idea is simple. A VAM looks at the year on year changes in the standardized test scores of students. The schools and teachers are then rated accordingly. When it is found that the scores regress or improve, schools and teachers get either the blame, or the credit. This process is actually similar to the one used in determining credit ..read more

Tissues Could Potentially be Regenerated by ‘Origami Organs’
Science News Journal
by SNJ
3y ago
Scientists and engineers from Northwestern Medicine have invented a new range of bioactive “tissue papers” that are manufactured from materials derived from organs. These papers are so flexible and thin that they can be folded into an origami bird. The new biomaterials could potentially be used to aid wound healing and to support natural hormone production in young cancer patients. Structural proteins excreted by cells that give organs their form and structure are used to make the tissue papers. A polymer is combined with the proteins to make the material pliable. During the research, differen ..read more

Dental Treatments May be Revolutionized With New Natural Tooth Repair Method
Science News Journal
by SNJ
3y ago
A team of researchers at King’s College London have developed a new method of stimulating living stem cells in tooth pulp to renew by using a drug normally used to treat Alzheimer’s disease. Although this is not strictly speaking a natural home remedy, the tooth does naturally heal itself. When a tooth is infected or suffers trauma, the soft inner pulp of the tooth is often exposed and infected. To seal the tooth pulp, a thin band of dentine is naturally produced to protect the tooth from infection, but this is not sufficient to repair large cavities effectively. Dentists currently fill holes ..read more

Sensitivity of Immunoassay Tests Boosted by More Than 1000 Times
Science News Journal
by SNJ
3y ago
Biomarkers are molecules that indicate a disease or the general health of an individual, and proteins are one of the most important biomarkers. This makes protein detection a critical component of a range of tests, ranging from the diagnosing of malaria, to the detection of heart attacks, and cancer monitoring and screening.  These biomarkers are most commonly detected by using a biochemical test known as an immunoassay. An immunoassay is also the basis of any pregnancy test. When the accuracy of any test is improved, it leads to results that are more precise. A significant improvement ha ..read more

An 8 Billion Ton Problem Called Plastic
Science News Journal
by SNJ
3y ago
Humans have created more than 8 billion metric tons of plastic since synthetic materials began being produced on a large scale in the early 1950s. This volume could cover the entire country of Argentina and most of the material has been dumped in landfills, or in the natural environment. Geyer, an associate professor at UCSB’s Bren School of Environmental Science & Management, and his team compiled a report containing production statistics for fibers, resins and additives. The data was taken from numerous industry sources and was catalogued according to type and consuming sector. The team ..read more

Rush Hour Pollution Much Higher Than Initially Thought
Science News Journal
by SNJ
3y ago
Measurements of pollutants that cause oxidative stress inside cars during rush hour traffic has revealed results that are potentially alarming. The levels of some of the harmful particulate matter inside a car cabin was found to be double that than was previously estimated. Traffic pollution sensors are normally placed on the ground next to the road and take continuous readings for 24 hours. Exhaust composition does however change so fast that drivers experience different conditions inside a vehicle than what is measured by roadside sensors. Sampling over a longer period also does not detect c ..read more

Scientists Decipher How our Brains Decide Which Words to Use
Science News Journal

3y ago
How the brain decides which is the one word you’re looking for between the smorgasbords of related concepts stored is a complicated cognitive task that is not really understood. Seeing an epilepsy patient with a grid of electrodes directly atop their brain had researchers looking into this question. They found that wide, overlapping bands of the brain work in parallel to retrieve the precise word from memory. When you look at a picture of a coffee cup, the neurons that store your memory of what a coffee cup is begin firing. It is however not an isolated process as many other neurons that code ..read more

Remnants of Permanent Early Human Settlements Found in the Andes
Science News Journal
by SNJ
3y ago
A team that included University of Wyoming researchers has used four different scientific approaches to give substantial support to the belief that humans lived in the Andean highlands of South America all year round more than 7,000 years ago. The scientists examined human remains and other archaeological findings obtained from a site at close to 12,500 feet above sea level in Peru and demonstrated that fearless hunter gathering parties consisting of men, women and children, were able to to survive at high elevation before the beginning of agriculture, in spite of frigid temperatures, the lack ..read more
