Cassava is the third-most important food source in tropical countries, but it has one major problem: The roots and leaves of poorly processed cassava plants contain a substance that, when eaten, can trigger the production of cyanide.
That’s a serious problem for the 500 million people who rely on cassava as their main source of calories, among them subsistence farmers in Sub-Saharan Africa, said Richard Sayre, a professor of plant biology at Ohio State University. He and his colleague Dimuth
Investigators at the Research Institute of the McGill University Health Centre (MUHC) have identified a gene that regulates the susceptibility to tuberculosis. This finding is published in this week’s edition of the Proceedings of the National Academy of Sciences.
Tuberculosis, an infectious disease caused by the bacteria Mycobacterium tuberculosis, affects approximately 1.9 billion people worldwide. However, a large proportion of these individuals do not develop tuberculosis symptoms. The
A team of radiologists and orthopedic specialists at Johns Hopkins Medicine has successfully used heat generated by electrode-tipped probes to destroy painful, benign bone tumors in eight of nine patients in a clinical study.
The results of the study, published in the March issue of the Journal of Vascular Interventional Radiology, suggests a need for further research to confirm the effectiveness of percutaneous radiofrequency for treating osteoid osteomas.
In the study, all eight
Web users who stick to one or two search engines and learn those well will have better results for their queries than users who try the same query or various engines, a Penn State researcher says.
“There are no wholesale rules about structuring a query that will work on multiple search engines,” said Bernard J. Jansen, assistant professor of information sciences and technology (IST). “And what works on one engine, such as narrowing a query, can have the opposite effect on other search engine
With the flexibility to check e-mail at home, get the kids ready for school, call your boss on the way to work, and text message your next appointment, the nature of work has changed. However, contrary to popular opinion, people who integrate their work and families are not always happier, Michigan State University researchers say.
Instead, Ellen Kossek, an MSU professor of Labor and Industrial Relations, found that people who establish boundaries between work and family are actually more
Astronomers from Cardiff University are completing the first survey ever for cosmic hydrogen, the primeval gas which emerged from the Big Bang to form all the stars and galaxies we can see today.
Since 1997 the astronomers, with their Australian colleagues, have been using two giant radio telescopes, the 64-metre diameter dish at Parkes in New South Wales, Australia, and the 76-metre dish at Jodrell Bank in Cheshire, England to build up an atlas of the heavens as mapped by cosmic hydrogen.
Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom “recoils” in…
The technique opens possibilities for exploring exotic states of matter and building new quantum materials. Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the…
Research at the south pole studied the mysterious quantum structure of space and time. Einstein’s theory of general relativity explains that gravity is caused by a curvature of the directions…
New sensor is six orders of magnitude more sensitive than the next best thing. A research team at Pitt led by Alexander Star, a chemistry professor in the Kenneth P. Dietrich…
New research shows how tiny plant-like organisms hitch a ride on ocean currents to reach darker and deeper depths, where they impact carbon cycling and microbial dynamics in the subtropical…
…without the application of phytohormones. Researchers develop a novel plant regeneration approach by modulating the expression of genes that control plant cell differentiation. For ages now, plants have been the…
Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements. The energy capacity and…
Engineers in Australia have found a new way to make power-pole insulators resistant to fire and electrical sparking, promising to prevent dangerous pole-top fires and reduce blackouts. Pole-top fires pose…
Potential alternative to widely used contrast agent gadolinium. Some of the world’s greatest discoveries happened by accident. While the discovery of diamond dust’s potential as a future MRI contrast agent…
A four-legged robot trained with machine learning by EPFL researchers has learned to avoid falls by spontaneously switching between walking, trotting, and pronking – a milestone for roboticists as well…
TUM professor uses ChatGPT for choreographies with flying robots. Prof. Angela Schoellig has proved that large language models can be used safely in robotics. ChatGPT develops choreographies for up to…
Compact, low-power system opens doors for photon-efficient drone and satellite-based environmental monitoring and mapping. Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D…
