Scientists have finally found malaria's Achilles' heel, a neurotoxin that isn't harmful to any living thing except Anopheles mosquitoes that spread malaria.
It's no surprise that using human embryos for biological and medical research comes with many ethical concerns. Correct though it is to proceed with caution in these matters, the fact is that much science would benefit from being able to study human biology more accurately.
More than 20 percent of the five staple crops that provide half the globe's caloric intake is lost to pests each year. Climate change and global trade drive the spread, emergence, and re-emergence of crop disease, and containment action is often inefficient, especially in low-income countries.
Scientists have discovered how plants create networks of air channels - the lungs of the leaf - to transport carbon dioxide (CO2) to their cells.
When a patient complains about chest pain, the diagnosis will usually involve catheter angiography to evaluate the adequacy of blood supply to the heart. Researchers from Charité - Universitätsmedizin Berlin have now established that, in certain cases, the diagnostic reliability of non-invasive coronary computed tomography (CT) angiography is as good as that of coronary angiography - thereby dispensing with the need for invasive procedures. Results from this research have been published in The BMJ*.
Serotonin is a multipurpose molecule found throughout the brain, playing a role in memory, cognition, and feelings of happiness and other emotions. In particular, researchers have long debated serotonin's role in sleep: Does serotonin promote sleep, or its opposite, wakefulness?
For patients with chest pain and presumably stable coronary heart disease (CHD), therapy depends primarily on how constricted the arteries that support the heart are (coronary arteries). This is often determined using an invasive procedure called cardiac catheterization.
For the first time, scientists have been able to study how well synthetic bone grafts stand up to the rigors and 'strains' of life, and how quickly they help bone re-grow and repair.
MIT researchers have devised a novel method to glean more information from images used to train machine-learning models, including those that can analyze medical scans to help diagnose and treat brain conditions.
Affecting around 115,000 people in the UK alone, Crohn's Disease is a lifelong condition which sees parts of the digestive system become inflamed. There is no precise cure and causes are believed to vary. But one indicator of the condition - an abnormal reaction of the immune system to certain bacteria in the intestines - has had new light shed on it thanks to scientists at the University of Plymouth.
Without being aware of it, people sometimes wrongly perceive tactile sensations. A new study in the scientific journal Current Biology shows how healthy people can sometimes misattribute touch to the wrong side of their body, or even to a completely wrong part of the body. The study was conducted by researchers at Bielefeld University's Cluster of Excellence CITEC, the University of Hamburg, and New York University.
A hair-sized probe that can measure key indicators of tissue damage deep in the lung has been developed by scientists. The new technology could pave the way for accurate monitoring of tissue in areas where existing technologies cannot reach.
A new study shows that the complement system, part of the innate immune system, plays a protective role to slow retinal degeneration in a mouse model of retinitis pigmentosa, an inherited eye disease. This surprising discovery contradicts previous studies of other eye diseases suggesting that the complement system worsens retinal degeneration.
A new multi-institution study spearheaded by researchers at Florida State University and the University of California, Los Angeles suggests a tiny protein could play a major role in combating heart failure related to Duchenne muscular dystrophy (DMD), the most common lethal genetic disorder among children.
Scientists in Japan have developed a way of amplifying DNA on a scale suitable for use in the emerging fields of DNA-based computing and molecular robotics. By enabling highly sensitive nucleic acid detection, their method could improve disease diagnostics and accelerate the development of biosensors, for example, for food and environmental applications.
