Overuse of agricultural chemicals on China’s small farms harms health and environment — ScienceDaily

Overuse of agricultural chemicals on China’s small farms harms health and environment: new study The size of farms in China is a key contributor to the overuse of agricultural chemicals, and as a result they may be too small to be environmentally sustainable, a new study has found. The research — conducted by a team from the Universities of Melbourne, Zhejiang, Fudan, Wuhan and Stanford — is published today in the Proceedings of the National Academy of Sciences. The study…

New technique speeds analysis of crop traits

Nebraska researchers have devised a more efficient and accurate way to scan the structural properties of plants. Credit: Yufeng Ge | Suresh Thapa | Scott Schrage A potted nine-leaf corn plant sits on a Frisbee-sized plate. The tandem begins rotating like the centerpiece atop a giant music box, three degrees per second, and after two minutes the plant has pirouetted to its original position. Another minute passes, and on a nearby screen appears a digital 3-D image in the palette…

Novel method to grow elastic diamonds — ScienceDaily

Diamonds is the strongest naturally occurring material on Earth. It is also renowned for its incomparable properties, such as high stiffness, exceptional thermal conductivity, high chemical resistance, and high optical transparency. Although these remarkable properties of diamond make it highly desirable for many scientific and technological applications, progress has been slow due to its brittleness. A recent study, affiliated with UNIST has unveiled that brittle diamonds can be bent and stretched elastically when made into ultrafine needles. This breakthrough has…

Drones will help investigators tackle chemical, biological and nuclear attacks

Credit: Shutterstock Researchers are making use of unarmed vehicles and robots to gather information and samples from crime or disaster scenes. Their initiative will help save lives. Risks that involve chemical, biological, radiological, nuclear and explosive (CBRNe) materials are among major safety concerns. Accidental or targeted, events caused by such agents could be hazardous to humans. They could also hinder and endanger any subsequent forensic investigations. To address the challenges involved in examining such incidents, researchers from the EU-funded…

STEM Cubs sees record-setting attendance

The 120+ students marked the highest attendance at a STEM Cubs event to date with more than 200 applications to participate. A total of 16 volunteers from Engineering and Education helped the event run smoothly. Photo by Trevor Liptak. Last weekend, Lafferre Hall played host to 120+ students for the third edition of STEM Cubs, the free engineering day camp that illustrates the importance of exploratory and experiential learning in science, technology, engineering and math for students from kindergarten through…

Understanding such a complicated organ is a massive scientific undertaking, and researchers often use simplified models to uncover small pieces of the neurological puzzle. In a report published in Micromachines, researchers at the…

A hidden world of communication, chemical warfare, beneath the soil — ScienceDaily

The soil supporting a field of crops teems with life. Untold numbers of bacteria and fungi strive for space and food. Most are harmless. Many are vital to creating healthy soil. But farmers worry about a handful of species that cause devastating crop diseases, and they often turn to chemical pesticides to keep those pathogens in check. New research shows how some of these harmful microbes have to contend not just with a farmer’s chemical attacks, but also with their…

What can snakes teach us about engineering friction?

Research from Drexel University paves the way for snake-inspired custom surface design. Credit: Drexel University If you want to know how to make a sneaker with better traction, just ask a snake. That’s the theory driving the research of Hisham Abdel-Aal, Ph.D., an associate teaching professor from Drexel University’s College of Engineering who is studying snake skin to help engineers improve the design of textured surfaces, such as engine cylinder liners, prosthetic joints—and yes, maybe even footwear. Abdel-Aal, a mechanical…

Rare earth element implicates garnet for continents’ missing iron, study finds — ScienceDaily

Clues from some unusual Arizona rocks pointed Rice University scientists toward a discovery — a subtle chemical signature in rocks the world over — that could answer a long-standing mystery: What stole the iron from Earth’s continents? The find has weighty implications. If the iron content of continental rocks was a bit greater, as it is in the rocks beneath Earth’s oceans, for example, our atmosphere might look more like that of Mars, a planet so littered with rusty, oxidized…

Study explores impact endocrine disruptors have on cardiovascular function, recommends investigating alternative biomaterials for medical device products used in hospital settings — ScienceDaily

More than 8 million pounds of bisphenol A (BPA) is produced each year and reaches 90 percent of the population through consumer and medical products. Epidemiological studies find BPA exposure in adults correlate with adverse cardiovascular events, ranging from abnormal heart beats, or arrhythmias, and angina, chest pain, to coronary artery disease, the narrowing of the arteries, commonly referred to atherosclerosis — the leading cause of death in the United Sates. Now, based on a study using neonatal rat heart…
