The wonder-material graphene could hold the key to unlocking the next generation of advanced, early stage lung cancer diagnosis.
A team of scientists from the University of Exeter has developed a new technique that could create a highly sensitive graphene biosensor with the capability to detect molecules of the most common lung cancer biomarkers.
Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser's capacity to do so is measured in terms of its linewidth, or coherence, which is the ability to emit a constant frequency over a certain period of time before that frequency changes.
Researchers at the Nagoya Institute of Technology (NITech) in Japan have demonstrated that a specific material can act as an efficient battery component for sodium-ion batteries that will compete with lithium-ion batteries for several battery characteristics, especially speed of charge.
The findings were published in Scientific Reports in November of 2018 and was headed by Naoto Tanibata, Ph.D., an Assistant Professor at the Department of Advanced Ceramics at NITech.
If you think traffic in city centers is bad now, just wait until self-driving cars emerge on the scene, cruising around to avoid paying hefty downtown parking fees.
Even worse, because cruising is less costly at lower speeds, self-driving cars will slow to a crawl as they "kill time," says transportation planner Adam Millard-Ball, an associate professor of environmental studies at the University of California, Santa Cruz.
Obesity - as research in the past decade has shown - is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular switch that controls the function of satiety neurons and therefore body weight. The findings were published in the journal Nature Metabolism.
Water molecules distort the electrical resistance of graphene, but a team of European researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact resistance is not impaired by humidity. This finding will help to develop new sensors -the interface between circuits and the real world- with a significant cost reduction.
A team of mathematicians has determined the ideal wing shape for fast flapping flight--a discovery that offers promise for better methods for harvesting energy from water as well as for enhancing air speed.
The work, which appears in the journal Proceedings of the Royal Society A, relies on a technique that mimics evolutionary biology to ascertain which structure yields the best pace.
New research today published in the European Journal of Neurology has found that women are twice as likely to suffer from severe depression following a stroke than men.
The team of researchers from King's College London followed the progress of symptoms over five years after stroke onset in 2,313 people (1,275 men and 1,038 women).
NEW YORK -- In a scientific first, Columbia neuroengineers have created a system that translates thought into intelligible, recognizable speech. By monitoring someone's brain activity, the technology can reconstruct the words a person hears with unprecedented clarity. This breakthrough, which harnesses the power of speech synthesizers and artificial intelligence, could lead to new ways for computers to communicate directly with the brain.
Anchiornis, one of the earliest feathered dinosaurs ever discovered, was found to have the ability to fly. However, could it fly like birds today? A new study published in the Proceedings of the National Academy of Sciences (PNAS) by researchers from China and the U.S. says no.
The flight feathers of modern birds are mainly composed of β-keratin, which gives them special biomechanical properties (such as flexibility, elasticity and strength) to meet the needs of flight.
