Cessation, or even retardation of the ageing process is an appealing notion that has captured the imagination of humans for millennia. Even if it were possible to rejuvenate our bodies or retard the ageing process, how do we measure this?

Study suggests new computer analytics may solve the hospital readmission puzzle
A University of Maryland School of Medicine study suggests that a novel machine learning model developed at the University of Maryland Medical System (UMMS), called the Baltimore score (B score), may help hospitals better predict which discharged patients are likely to be readmitted.

Trump ends fetal tissue research by federal scientists
The Trump administration said Wednesday it is ending medical research by government scientists that uses human fetal tissue, overriding the advice of scientists that there's no other way to tackle some health problems and handing abortion opponents a major victory.

Researchers try to recreate human-like thinking in machines
Researchers at Oxford University have recently tried to recreate human thinking patterns in machines, using a language guided imagination (LGI) network. Their method, outlined in a paper pre-published on arXiv, could inform the development of artificial intelligence that is capable of human-like thinking, which entails a goal-directed flow of mental ideas guided by language.

Glacial sediments greased the gears of plate tectonics
Earth's outer layer is composed of giant plates that grind together, sliding past or dipping beneath one another, giving rise to earthquakes and volcanoes. These plates also separate at undersea mountain ridges, where molten rock spreads from the centers of ocean basins.

A 3-D printer powered by machine vision and artificial intelligence
Objects made with 3-D printing can be lighter, stronger, and more complex than those produced through traditional manufacturing methods. But several technical challenges must be overcome before 3-D printing transforms the production of most devices.

Shared control allows a robot to use two hands working together to complete tasks
A team of researchers from the University of Wisconsin and the Naval Research Laboratory has designed and built a robotic system that allows for bimanual robot manipulation through shared control. In their paper published in the journal Science Robotics, the group explains the ideas behind their work and how well they worked in practice.

Psychedelic drugs: Would you accept a prescription?
In countries such as the UK, US and Australia, strict laws and international conventions prohibiting the use of psychedelic drugs have made it almost impossible to research how these drugs work, and how they might be used to heal instead of harm—until recently. These barriers—together with cost, ethics committees, ideologically driven myths and stigma—have delayed research into a promising area of medicine. But things are changing for the better, as evidence and unmet need are at last being recognised.

Maternal blood test is effective for Down syndrome screening in twin pregnancies
Cell-free DNA (cfDNA) testing, which involves analyzing fetal DNA in a maternal blood sample, is a non-invasiveness and highly accurate test for Down syndrome in singleton pregnancies, but its effectiveness in twin pregnancies has been unclear. A new analysis published in Ultrasound in Obstetrics & Gynecology reveals that cfDNA testing for Down syndrome in twins is just as effective as in singletons, with a detection rate of 98% and only a 0.05% rate of misdiagnosis.

Researchers identify link between more frequent, intense heat events and deaths in Las Vegas
Over the last several decades, extreme heat events around the world—particularly in the American Southwest—have gotten hotter, occurred more frequently, and lasted longer. These trends pose significant health risks to the growing number of people making cities like Las Vegas home.

Visible public health leadership needed to boost vaccine coverage
Public health expert Professor John Ashton is calling for local directors of public health to provide visible leadership to address the recent systematic deterioration of vaccine coverage levels. Writing in the Journal of the Royal Society of Medicine, he describes recent falls in the uptake of other preventative programmes, including bowel, breast and cervical cancer and aortic aneurysm. This, he writes, indicates the fragmentation and weakening of the arrangements for public health, and especially the links with the NHS, since the 2013 reorganisation when directors of public health moved to local government.

New organic flow battery brings decomposing molecules back to life
After years of making progress on an organic aqueous flow battery, Harvard University researchers ran into a problem: the organic anthraquinone molecules that powered their ground-breaking battery were slowly decomposing over time, reducing the long-term usefulness of the battery.

Using sensors to improve the interaction between humans and robots walking together
Researchers at the BioRobotics Institute of Scuola Superiore Sant"Anna, Co-Robotics srl and Sheffield Hallam University have recently proposed a new approach to improve interactions between humans and robots as they are walking together. Their paper, published in MDPI's Robotics journal, proposes the use of wearable sensors as a means to improve the collaboration between a human and a robot that are moving around in a shared environment.
