Scientists at Johns Hopkins Medicine have mapped a molecular pathway in human breast and lung cells that could lead to excessive genome duplication, a hallmark of cancer cells. The findings, recently published in the journal Science, reveal what goes wrong when a group of molecules and enzymes trigger and regulate what’s known as the “cell cycle,” the [...]
In emergency rooms and intensive care units nationwide, healthcare professionals must quickly decide on antibiotics for patients suspected of having severe infections. A recent study from the University of Michigan indicates that these rapid decisions could lead to unexpected effects on patient outcomes. Beginning in 2015, a 15-month national shortage of a commonly prescribed antibiotic, piperacillin/tazobactam, [...]
A team of experts, including Monash University researchers, has developed a new technique to implement quantum-safe digital signatures twenty times faster, resulting in speedier and safer online transactions than ever before. The research, published recently in IEEE Transactions on Parallel and Distributed Systems, is the first to develop a much faster way to implement Falcon—a post-quantum [...]
When water freezes, it transitions from a liquid phase to a solid phase, resulting in a drastic change in properties like density and volume. Phase transitions in water are so common most of us probably don't even think about them, but phase transitions in novel materials or complex physical systems are an important area [...]
A new technique for 3D printing medication has enabled the printing of multiple drugs in a single tablet, paving the way for personalized pills that can deliver timed doses. Researchers from the University of Nottingham's, Centre for Additive Manufacturing have led research alongside the School of Pharmacy that has fabricated personalized medicine using Multi-Material [...]
Researchers have created a new vaccine technology that, in tests with mice, has demonstrated protection against a wide variety of coronaviruses, including those that could cause future disease outbreaks—even those not yet identified. This is a new approach to vaccine development called ‘proactive vaccinology’, where scientists build a vaccine before the disease-causing pathogen even [...]
Numerous artificial intelligence (AI) systems, even those designed to be helpful and truthful, have already learned how to deceive humans. In a review article recently published in the journal Patterns, researchers highlight the dangers of AI deception and urge governments to quickly establish robust regulations to mitigate these risks. “AI developers do not have a [...]
A novel MRI technique developed at MIT allows for detailed imaging of bioluminescence deep within the brain, offering new insights into how brain cells develop and communicate with each other. Scientists often label cells with proteins that glow, allowing them to track the growth of a tumor, or measure changes in gene expression that occur as [...]
In a first-ever human clinical trial of four adult patients, an mRNA cancer vaccine created at the University of Florida rapidly reprogrammed the immune system to target glioblastoma, the deadliest and most aggressive form of brain tumor. The results mirror those in 10 pet dog patients suffering from naturally occurring brain tumors whose owners approved of [...]
A cubic millimeter of brain tissue may not sound like much. But considering that tiny square contains 57,000 cells, 230 millimeters of blood vessels, and 150 million synapses, all amounting to 1,400 terabytes of data, Harvard and Google researchers have just accomplished something enormous. A Harvard team led by Jeff Lichtman, the Jeremy R. [...]
