New evidence suggests that we can "bank" muscle growth potential in our teens to prevent frailty in old age. It also suggests that athletes who cheat and grow their muscles with steroids may go undetected.

Study in mice, people explains why poor sleep linked to Alzheimer's.

A form of rare genomic structural variation called copy number variants (CNVs) may be more closely associated with schizophrenia than bipolar disorder.

Anxiety disorders are severe mental disorders in which patients suffer from intense fears and anxiety or from sudden, inexplicable panic attacks. In extreme cases, the affected individuals barely leave their homes, which can have serious consequences for their relationships with family and friends as well as for their professional lives. Scientists have now identified a synaptic protein which, when inactivated, has an anxiolytic effect in mice.

New research suggests that our brains are like modern washing machines – evolved to have the latest sophisticated programming, but more vulnerable to breakdown and prone to develop costly disorders. Researchers compared the efficiency of the neural code in non-human and human primates, and found that as the neural code gets more efficient, the robustness that prevents errors is reduced.

Robots performing in surgeries, robots in automobile production, and robots in caregiving. In some areas, machines are already well-established, in others they are on the rise. But how do people feel about robots? Apparently, increasingly uncomfortable. Thatis the verdict of a cross-European data analysis that shows robots were evaluated more negatively in 2017 than five years before.

Doctors in intensive care units face a continual dilemma: Every blood test they order could yield critical information, but also adds costs and risks for patients. To address this challenge, researchers from Princeton University are developing a computational approach to help clinicians more effectively monitor patients’ conditions and make decisions about the best opportunities to order lab tests for specific patients.

Modern technology makes it possible to sequence individual cells and to identify which genes are currently being expressed in each cell. These methods are sensitive and consequently error prone. Researchers have now developed algorithms that make it possible to predict and correct potential sources of error.

Stable simulations of DNA crystals have been achieved for the first time, enabling scientists to explain the importance of chemical additives used experimentally to achieve suitable crystallization conditions and stable crystals in the laboratory.

Researchers have conducted an observational study in doctors where they found that DNA breaks increase after sleep deprivation.
