In many places in the United States, low-level criminal offenses—having an open container, for example, or disorderly conduct—can result in a ticket and a subsequent court date, and failing to show up to that appointed court time can lead to an arrest warrant. In New York City alone in 2015, 40% of defendants or about 100,000 people missed court dates for this type of offense.
As we learned in chemistry class, chemical reaction occurs with the formation or cleavage of bonds between atoms. These chemical bonds form when atoms share or exchange electrons. The chemical reactivity can be controlled in several ways. Among them, the control of electronic property at the reaction site is generally employed. For example, electron-rich molecule prefers to react with a molecule that can readily accept electrons. Many atoms can form 'functional groups' that either donate or withdraw electrons and control the electron density distribution of a molecule.
Researchers from St. Petersburg provided a unique experiment. They implanted a polymer scaffold as a vascular prosthesis into the rat abdominal aorta and monitored the process of its bioresobtion for 16 months. An artificial vessel was formed where the scaffold was located. It posess similar characteristics as a natural vessel. The scaffold itself showed high patency, biocompatibility and non-toxicity.
Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology and push scientific boundaries further. A key aspect of long-term human spaceflight is the physiological response and the consequent microgravity (0G) adaptation, which has all the features of accelerated aging involving almost every body system: muscle atrophy and bone loss, onset of balance and coordination problems, loss of functional capacity of the cardiovascular system.
Field Effect Transistors (FET) are the core building blocks of modern electronics such as integrated circuits, computer CPUs and display backplanes. Organic Field Effect Transistors (OFETs), which use organic semiconductor as a channel for current flows, have the advantage of being flexible when compared with their inorganic counterparts like silicon.
Efforts to find ways to break down cellulose, the tough stuff that makes up plant cell walls, faster and more productively has long been a goal of industrial researchers.
When plants are processed into biofuels or other biomass applications, cellulose has to be degraded into simpler sugar molecules first, and this step can represent up to a quarter of the operating and capital costs of biofuel production. If this process can be made faster and more productive, it won't just save industry money, but such efficiencies could also reduce the environmental impact of production.
Heating the space where we live or work is a common necessity in most of the inhabited areas. The energy requested for this process is responsible for a third of all the energy consumed in Europe; moreover, 75% of this energy is produced with fossil fuels.
Designing solar panels in checkerboard lines increases their ability to absorb light by 125 per cent, a new study says.
Researchers say the breakthrough could lead to the production of thinner, lighter and more flexible solar panels that could be used to power more homes and be used in a wider range of products.
A "danger molecule" is higher in the blood of younger black adults than whites, females than males and increases with weight and age, researchers report in the first large, longitudinal study associating circulating HMGB1 levels with obesity, inflammation promoters and early indicators of cardiovascular risk in humans.
CHAMPAIGN, Ill. -- The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout from branches and eventually reach the soil. The tree also has a unique relationship with a wasp that has coevolved with it and is the only insect that can pollinate it.
In a new study, researchers identify regions in the banyan fig's genome that promote the development of its unusual aerial roots and enhance its ability to signal its wasp pollinator.
Multidisciplinary tumor boards are vital to cancer treatment plans, bringing together clinicians from different specialties to guide patient treatment and improve outcomes. However, compiling the relevant data for each case is time-consuming and requires contributions from multiple team members. To optimize the process, researchers at the MU School of Medicine partnered with Roche Diagnostics to evaluate a cloud-based product called NAVIFY® Tumor Board that integrates all relevant clinical data for a tumor board into a single digital dashboard accessible to everyone.
Physicists have created a broadband detector of terahertz radiation based on graphene. The device has potential for applications in communication and next-generation information transmission systems, security and medical equipment. The study came out in ACS Nano Letters.
About a year ago, researchers found fossil specimens of beetles in an amber deposit in Myanmar, thereby describing a new beetle family that lived about 99 million years ago. However, the scientists had not been able to fully describe the morphology of the insects in the amber sample, which is why the beetles were subsequently given the mysterious name Mysteriomorphidae.
The term "greenhouse gas" is often used interchangeably with carbon dioxide, due to its prevalence in our atmosphere - more than 80 percent of all greenhouse gas emissions, estimates the Environmental Protection Agency. But another greenhouse gas, nitrous oxide (N2O), can have effects with far greater impact.
And, according to a recent study, N2O emissions are increasing at a "devastating" rate, faster than predictions introduced by the Intergovernmental Panel on Climate Change.
A coordinated effort on Twitter to influence the upcoming U.S. presidential election -- using trolls (fake personas that spread hyper-partisan themes) and super-connectors (highly-networked accounts) -- aims to sow distrust, exacerbate political divisions and undermine confidence in American democracy, according to a new RAND Corporation report.
