Smaller beetles who consistently lose fights over resources can gain a competitive advantage over their larger rivals by teaming up with another species.
In a study featuring a miniature 'gym' for beetles (complete with beetle treadmills), researchers from the University of Cambridge found that beetles who consistently lose out to members of their own species have the most to gain by forming a mutually-beneficial cross-species partnership.
Researchers at Tokyo Institute of Technology (Tokyo Tech) have developed an easy-to-use, tunable biosensor tailored for the terahertz range. Images of mouse organs obtained using their new device verify that the sensor is capable of distinguishing between different tissues. The achievement expands possibilities for terahertz applications in biological analysis and future diagnostics.
It's the small pieces that make the big picture, and in this case, the pieces can't be seen by the naked eye. New research at the Okinawa Institute of Science and Technology Graduate University (OIST) used microscopy techniques to piece together the brain of the millimeter-long Caenorhabditis elegans, revealing that their neurons fire action potentials - a spike in voltage due to neurons sending sensory information in the cell membrane.
Rice University physicists Matthew Foster and Seth Davis want to view a vexing quantum puzzle from an entirely new perspective. They just need the right vantage point and a place colder than deep space.
Not every embryo contains 46 perfect chromosomes. Some have more, others have fewer. The result is a common abnormality known as aneuploidy, which occurs in as many as 80 percent of human embryos.
Because aneuploidy has been linked to a risk of in vitro fertilization failure, miscarriage and certain genetic orders or birth defects, mosaic embryos, those with both normal and abnormal cells, have not been considered ideal candidates for IVF transfer.
For many individuals who only produce mosaic embryos, this can mean that the IVF journey may end before it begins.
A popular theme in the movies is that of an incoming asteroid that could extinguish life on the planet, and our heroes are launched into space to blow it up. But incoming asteroids may be harder to break than scientists previously thought, finds a Johns Hopkins study that used a new understanding of rock fracture and a new computer modeling method to simulate asteroid collisions.
Tokyo - Materials that have a disordered structure with no regular repeating pattern are described as amorphous. Such materials can be found in nature and also have a variety of applications in technology. However, the disordered nature of these materials makes them more challenging to characterize than crystalline structures.
CAMBRIDGE, Mass. -- Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.
Why do we become more positive as we grow older? Why are adolescents so sensitive to negative social cues?
Researchers at Tokyo Institute of Technology (Tokyo Tech) report a unipolar n-type transistor with a world-leading electron mobility performance of up to 7.16 cm2 V-1 s-1. This achievement heralds an exciting future for organic electronics, including the development of innovative flexible displays and wearable technologies.
Researchers worldwide are on the hunt for novel materials that can improve the performance of basic components required to develop organic electronics.
Princeton University researchers are gaining new insights into the causes and characteristics of diseases by harnessing machine learning to analyze molecular patterns across hundreds of diseases simultaneously. Demonstrating a new tool now available to researchers worldwide, the team of computer scientists and biologists has already uncovered and experimentally confirmed previously unknown contributions of four genes to a rare form of cancer that primarily affects babies and young children.
Brain tumors vary widely in how they respond to treatment. However, early assessment of therapy response is essential in order to choose the best possible treatment for the patient. Scientists from the German Cancer Research Center (DKFZ) have now been able to show in a study using non-invasive high-resolution 7-Tesla MRI scans that the protein content of tumors correlates with response to treatment and survival.
SAN DIEGO -- Experimental photonic switches tested by researchers at the University of California, Berkeley, U.S.A., show promise toward the goal of fully optical, high-capacity switching for future high-speed data transmission networks. The switch developed and tested for this research demonstrated capabilities not seen before in photonic switches.
Researchers have developed an algorithm that safeguards hardware from attacks to steal data. In the attacks, hackers detect variations of power and electromagnetic radiation in electronic devices' hardware and use that variation to steal encrypted information.
Researchers with the University of Wyoming and the University of Cincinnati recently published their work in the Institute of Engineering and Technology Journal.
SYRACUSE, N.Y. - Researchers in the Syracuse University College of Engineering and Computer Science have developed a material--a new kind of shape memory polymer (SMP)--that could have major implications for health care.
SMPs are soft, rubbery, "smart" materials that can change shape in response to external stimuli like temperature changes or exposure to light. They can hold each shape indefinitely and turn back when triggered to do so.
