Some of the most popular social media sites are filled with images of extremely thin women that might be harmful to those who view them — whether they are seeking them or not, according to research. The images were often cropped to remove heads or focus on just a few body parts.
Object recognition — determining what objects are where in a digital image — is a central research topic in computer vision. Researchers have now demonstrated that, en route to learning how to recognize scenes, a new computer system also learned how to recognize objects.
Patience and persistence are beginning to pay off for one researcher whose research about the behavior of cell proteins in childhood cancer was started by identifying a large number of signaling proteins using mass spectrometry. He collected more data than he knew what to do with, he says.
Scientists have gained ground toward developing more targeted therapies for the most common childhood brain tumor. The findings involve the DDX3X gene. In 2012, other work highlighted DDX3X as a promising focus for efforts to develop targeted therapies against medulloblastoma. Such treatments target the genetic mistakes that give rise to the brain tumor’s four subtypes.
An EEG study shows chocolate can increase brain characteristics of attention and significantly affect blood pressure levels. Historically, chocolate has been recognized as a vasodilator, meaning that it widens blood vessels and lowers blood pressure in the long run, but chocolate also contains some powerful stimulants. Researchers wanted to investigate if people who consume chocolate would see an immediate stimulant effect.
Therapies that specifically target mutations in a person’s cancer have been much-heralded in recent years, yet cancer cells often find a way around them. To address this, researchers identified a promising combinatorial approach to treating glioblastomas, the most common form of primary brain cancer.
