Scientists have identified two subtypes of metastatic prostate cancer that respond differently to treatment, information that could one day guide physicians in treating patients with the therapies best suited to their disease. Building off of earlier studies that discovered clinically relevant subtypes of breast cancer and non-metastatic prostate cancer, researchers identified genetic signatures that can […]

Traumatic brain injury (TBI) and other injuries to blood vessels in the brain, like stroke, are a leading cause of long-term disability or death. Researchers at the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, have found a possible explanation for why some patients recover much more poorly […]

Two previously invisible galaxies completely hidden by clouds of cosmic gas and dust have been discovered by an international team of researchers. While investigating new data of young, extremely distant galaxies observed with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, astronomers noticed unexpected emissions coming from seemingly empty regions of space. The team, which […]

Disambiguation: In uncomplicated, easy-to-understated wording, disambiguate means to make clear. Like most, I was once schooled on matters of how to write, form a sentence, parts of sentences, punctuation, grammar and the like. Without proper context or a proper frame of reference in this regard, things can get fairly confusing, fairly quickly as I discovered […]

A DNA robot that can walk across biological cell membranes is the first one that can control living cells’ behaviour. The researchers who made the robot hope that it could improve cell-based precision medicine. A team led by Hong-Hui Wang and Zhou Nie from Hunan University, China, has created a synthetic molecular robot that walks […]

Can specific dietary guidelines help people living with bipolar disorders better manage their health? Maybe someday, according to a new study by Penn State College of Medicine researchers. Clinical trial results showed that a diet designed to alter levels of specific fatty acids consumed by participants may help patients have less variability in their mood. […]

While marijuana use may impact some genes linked to autism in men’s sperm, abstaining from cannabis consumption over time may significantly lower many of those effects, according to a study by Duke Health researchers. This study, appearing online in Environmental Epigenetics on Sept. 21, followed several other studies at Duke that linked cannabis use to alterations […]

The study of numbers has driven mathematics since antiquity. The constantly evolving field of arithmetic connects numbers and geometry, and is used in everyday applications, particularly in cryptography. Aside from being a bad draw at Scrabble, the letters N, Z, D, Q, R, and C symbolise series of numbers for mathematicians. For example, N designates […]

A new sensor can detect not only whether a virus is present, but whether it’s infectious – an important distinction for containing viral spread. Researchers at the University of Illinois Urbana-Champaign and collaborators developed the sensor, which integrates specially designed DNA fragments and nanopore sensing, to target and detect infectious viruses in minutes without the […]

A species of roundworm that is widely used in biological research can sense and respond to sound, despite having no ear-like organs, according to a new study from the University of Michigan Life Sciences Institute. The findings, scheduled to publish Sept. 22 in the journal Neuron, offer a new biological tool for studying the genetic […]
