A novel class of antimalarial compounds that can effectively kill malaria parasites has been developed by Australian and US researchers.
In preclinical testing, the compounds were effective against different species of malaria parasites, including the deadly Plasmodium falciparum, and at multiple stages of the parasite lifecycle. The compounds target a previously unexplored parasite pathway and could overcome existing issues of parasite drug resistance, an ongoing and increasingly urgent problem.
Hydrate formation has long been a problem for hydrocarbon production in the Arctic. Kazan Federal University's EcoOil research unit works on inhibitors to help mitigate the problem - one of the results was publicized by us just recently.
In recent times, researchers have increasing found that the power of computers and artificial intelligence is enabling more accurate diagnosis of a patient's current heart health and can provide an accurate projection of future heart health, potential treatments and disease prevention.
Someday, microscopic robots could perform useful functions, such as diagnostic testing in lab-on-a-chip sensors, micropatterning surfaces or repairing equipment in tight spaces. But first, scientists need to be able to tightly control the microbots' speed. Now, researchers reporting in ACS' Chemistry of Materials have developed micromotors with three "engines" that they can control separately with chemical fuel, magnets and light.
The growth of agriculture led to unprecedented cooperation in human societies, a team of researchers, has found, but it also led to a spike in violence, an insight that offers lessons for the present.
WASHINGTON -- Researchers have incorporated ultra-thin optical devices known as metasurfaces into off-the-shelf contact lenses to correct deuteranomaly, a form of red-green color blindness. The new customizable contact lens could offer a convenient and comfortable way to help people who experience various forms of color blindness.
ORLANDO, March 4, 2020 - Sea level rise and hurricanes are a threat to sea turtle nesting habitat along national seashores in the Southeast, but a new study predicts the greatest impact to turtles will be at Canaveral National Seashore.
An improved method to predict the temperature when plastics change from supple to brittle, which could potentially accelerate future development of flexible electronics, was developed by Penn State College of Engineering researchers.
Next-generation flexible electronics, such as bendable displays and medical implants, will rely on semiconductor materials that are mechanically flexible. Accurate predictions of the temperature when embrittlement occurs, known as the glass transition temperature, is crucial to design conducting polymers that remain flexible at room temperature.
Researchers at the University of Bristol have come up with a new type of nanoelectromechanical relay to enable reliable high-temperature, non-volatile memory.
The work, which is reported in Nature Communications, was carried out in collaboration with the University of Southampton and the Royal Institute of Technology, Sweden.
The invention is an important development for all-electric vehicles and more-electric aircraft which require electronics with integrated data storage that can operate in extreme temperatures with high energy efficiency.
CABI scientists, as part of an international team of researchers, have discovered a new biological control in the fight against the highly noxious and invasive weed parthenium (Parthenium hysterophorus) in Pakistan.
As outlined in a new paper published in the journal BioInvasions Records, the scientists report the first record of the rust species Puccinia abrupta var. partheniicola - more commonly known as winter rust - in the Punjab and Khyber Pakhtunkhwa Provinces.
Johns Hopkins Medicine researchers report that the number of disabled students admitted to U.S. medical schools rose from 2.9% to 4.9% over the last three years. However, the percentage of NIH-funded researchers with disabilities declined between 2008 and 2018. The grant success rate for this group was lower than for researchers without a disability, indicating that despite more people with disabilities prepared to enter biomedical research, their prospects as professionals are weakening.
ANN ARBOR--Researchers at the University of Michigan have raised serious concerns with the performance of some arsenic test kits commonly used in Bangladesh to monitor water contamination.
Their study tested eight commercially available arsenic test kits, and found that several--including the most widely used in Bangladesh--performed poorly.
Smoking doubles the risk of developing rheumatoid arthritis and continuing to smoke after being diagnosed has negative effects on patients. In an Arthritis Care & Research study of patients with rheumatoid arthritis who smoked, certain healthcare factors were linked with a higher likelihood that patients would quit smoking.
The Southern High Plains of the United States have low annual rainfall. When it does rain, though, intense storms can cause severe soil erosion. Strong winds also strip away valuable topsoil.
Enter cover crops.
Usually grown during seasons when primary crops aren't cultivated, cover crops can include legumes such as pea and hairy vetch, or grassy crops like oats and barley.
Cover crops do more than just cover fields between growing seasons. They help soils retain rainwater and reduce erosion from wind and water.
For a long time, nothing. Then all of a sudden, something. Wonderful things in nature can burst on the scene after long periods of dullness -- rare events such as protein folding, chemical reactions, or even the seeding of clouds. Path sampling techniques are computer algorithms that deal with the dullness in data by focusing on the part of the process in which the transition occurs.
