PITTSBURGH--Researchers at Carnegie Mellon University have developed a system that can accurately locate a shooter based on video recordings from as few as three smartphones.
When demonstrated using three video recordings from the 2017 mass shooting in Las Vegas that left 58 people dead and hundreds wounded, the system correctly estimated the shooter's actual location -- the north wing of the Mandalay Bay hotel. The estimate was based on three gunshots fired within the first minute of what would be a prolonged massacre.
Three in four patients with anorexia nervosa -- including many with challenging illness -- make a partial recovery. But just 21 percent make a full recovery, a milestone that is most likely to signal permanent remission.
Most analytical methods in biology require invasive procedures to analyze samples, which leads to irreversible changes or even their destruction. Furthermore, the sensitivity of such approaches often stems from the averaging of signals generated by a large number of cells, making it impossible to study the underlying heterogeneity of responses.
Harvesting energy from walking human body Lightweight smart materials-based energy harvester develop
Specifically, the device can capture biomechanical energy from the motion of the human knee and then convert it to electricity which can be used to power wearable electronics such as pedometers, health monitors, and GPS. This work has been published in Applied Physics Letters and recommended as a featured article by editors.
Self-driving cars have become better and more reliable in recent years. Before they might be allowed to drive completely autonomously on our roads in the near future, however, a few hurdles have to be taken. Above all, the need to assess the surroundings at lightning speed and to recognize people and obstacles takes current technologies to its limits.
An article of the IKBFU Director of Institute of Physics, Mathematics and Informational Technology, Artyom Yurov and the Institute's Associate Professor, Valerian Yurov was recently published in European Physical Journal. The scientists have released their calculations, according to which the Universe may have quantum properties.
Artyom Yurov explained:
Microscopes have been at the center of many of the most important advances in biology for many centuries. Now, KAUST researchers have shown how a standard microscope can be adapted to provide even more information.
A new suicide prevention programme which includes swift access to specialist care and 12 months of telephone follow-ups has shown to reduce deaths by 17 per cent.
The programme, called Suicide Prevention by Monitoring and Collaborative Care (SUPREMOCOL) brought together care services and key community agencies to create a cohesive network who worked together with the aim of diminishing preventable deaths by suicide.
WASHINGTON, D.C., November 19, 2019 -- Blood clots have long been implicated in heart attacks and strokes, together accounting for almost half of deaths annually in the United States. While the role of one key protein in the process, called von Willebrand factor, has been established, a reliable model for predicting how vWF collects in blood vessels remains elusive.
WASHINGTON, D.C., November 19, 2019 -- Coordinated behavior is common in a variety of biological systems, such as insect swarms, fish schools and bacterial colonies. But the way information is spread and decisions are made in such systems is difficult to understand.
A group of researchers from Southeast University and China University of Mining and Technology studied the synchronized flight of pigeon flocks. They used this as a basis to explain the mechanisms behind coordinated behavior, in the journal Chaos, from AIP Publishing.
SAN FRANCISCO, CA November 19, 2019--For a person with Alzheimer's disease, there's no turning back the clock. By the time she begins to experience memory loss and other worrisome signs, cognitive decline has already set in. And decades of clinical trials have failed to produce treatments that could help her regain her memory.
Activation of CD95, a receptor found on all cancer cells, triggers programmed cell death - or does the opposite, namely stimulates cancer cell growth. Scientists from the German Cancer Research Center (DKFZ) have now shown that the impact of CD95 activation depends on whether there are isolated cancer cells or three-dimensional structures. Individual cells are programmed to die following CD95 activation. In contrast, CD95 activation stimulates growth in clusters of cancer cells, for example in solid tumors.
What The Study Did: This study examined state laws that grant individuals and institutions rights to refuse participation in abortion based on their beliefs, that grant immunity from liability for such refusals, and that limit conscience rights when patient safety is at risk.

Some continuous glucose monitoring (CGM) alarm features and settings may achieve better blood sugar control for people with type 1 diabetes, according to a study published in the Journal of the Endocrine Society.
To investigate the problem of click interception, the research team led by Professor Wei Meng of the Department of Computer Science and Engineering, Faculty of Engineering, The Chinese University of Hong Kong (CUHK) developed a browser-based analysis framework - Observer, which is able to detect three different techniques for intercepting web user clicks. The research result has been published in USENIX Security Symposium 2019 (USENIX Security '19), one of the top academic conferences in computer security.
