Extreme exercise can strain the heart without causing permanent damage
Researchers have found no evidence of elevated cardiac risk in runners who completed a 24-hour ultramarathon (24UM), despite the transient elevation of blood biomarkers that measure cardiac health. According to the study in the journal Heliyon, published by Elsevier, trained runners were more likely than their novice counterparts to experience raised levels, reflecting the greater cardiac load and pituitary-adrenocortical response to extremely strenuous exercise.

Drag-and-drop data analytics
In the Iron Man movies, Tony Stark uses a holographic computer to project 3-D data into thin air, manipulate them with his hands, and find fixes to his superhero troubles. In the same vein, researchers from MIT and Brown University have now developed a system for interactive data analytics that runs on touchscreens and lets everyone—not just genius, billionaire, playboy philanthropists—tackle real-world issues.

The RoboBee flies solo—Cutting the power cord for the first untethered flight
The RoboBee—the insect-inspired microrobot developed by researchers at Harvard University—has become the lightest vehicle ever to achieve sustained flight without the assistance of a power cord. After decades of work, the researchers achieved untethered flight by making several important changes to the RoboBee, including the addition of a second pair of wings. That change, along with less visible changes to the actuators and transmission ratio, gave the RoboBee enough lift for the researchers to attach solar cells and an electronics panel.

One simple change cut unnecessary imaging for cancer patients in half
Simply introducing a default physician order—a "nudge"—into electronic health records (EHRs) cut the use of unnecessary daily imaging in half during palliative radiation therapy sessions for patients with advanced cancer, according to a Penn Medicine study published today in JAMA Oncology. While daily imaging is typically used in curative cancer treatment, national guidelines recommend providers transition to weekly imaging for palliative radiotherapy sessions. Daily imaging unnecessarily extends the duration of each radiation therapy session for palliative care patients who are often in pain or discomfort from the progression of cancer.

Early detection of schizophrenia
Detecting and treating schizophrenia early, perhaps even before symptoms arise, could lead to better therapeutic outcomes. Studies have demonstrated differences in social function and cognition among people who later develop symptoms of schizophrenia, but less is known about pre-morbid temperament and personality.
