Proof it's possible to enhance or suppress memories

What if scientists could manipulate your brain so that a traumatic memory lost its emotional power over your psyche? Steve Ramirez, a Boston University neuroscientist fascinated by memory, believes that a small structure in the brain could hold the keys to future therapeutic techniques for treating depression, anxiety, and PTSD, someday allowing clinicians to enhance positive memories or suppress negative ones.

This robot helps you lift objects—by looking at your biceps

We humans are very good at collaboration. For instance, when two people work together to carry a heavy object like a table or a sofa, they tend to instinctively coordinate their motions, constantly recalibrating to make sure their hands are at the same height as the other person's. Our natural ability to make these types of adjustments allows us to collaborate on tasks big and small.

Exposure to air pollution before and after birth may affect fundamental cognitive abilities

A growing body of research suggests that exposure to air pollution in the earliest stages of life is associated with negative effects on cognitive abilities. A new study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa," has provided new data: exposure to particulate matter with a diameter of less than 2.5 μm (PM2.5) during pregnancy and the first years of life is associated with a reduction in fundamental cognitive abilities, such as working memory and executive attention.

New framework improves performance of deep neural networks

North Carolina State University researchers have developed a new framework for building deep neural networks via grammar-guided network generators. In experimental testing, the new networks—called AOGNets—have outperformed existing state-of-the-art frameworks, including the widely-used ResNet and DenseNet systems, in visual recognition tasks.

Startup to commercialize blood test for most major cancers

When testing for such as lung cancer disease, doctors know that tissue biopsies are necessary and potentially life-saving, though the procedures used to gather tissue can lead to dangerous complications, from bleeding to lung collapse. To lower the need for invasive procedures, researchers at the University of Arizona developed a new blood test that can detect most major cancers and have launched a startup, DesertDx, to bring the invention to doctors and their patients.

Do physicians properly advise women with dense breasts on cancer risk?

A new study has shown that more than half of physicians—primary care doctors and specialists—may be unaware that dense breasts are associated with an increased risk of breast cancer, and nearly half reported not being aware of laws requiring physicians to inform women about mammography-related breast density risks and supplemental screening options. This timely and newsworthy study, which also compared the knowledge and practices of primary care physicians to specialists regarding breast density, is published in Journal of Women's Health.

Researchers find adding a protein to lentiviral vectors protects them from immune system

A team of researchers from institutions in Italy and the U.S., in conjunction with several corporate entities, has found that adding a protein to lentiviral vectors can protect them from an immune system attack. In their paper published in the journal Science Translational Medicine, the group describes their work in finding new ways to treat hemophilia and how well their approach worked in monkeys.
