When a parent and infant interact, various aspects of their behaviour can synchronise, including their gaze, emotions and heartrate, but little is known about whether their brain activity also synchronises - and what the consequences of this might be.

Brainwaves reflect the group-level activity of millions of neurons and are involved in information transfer between brain regions. Previous studies have shown that when two adults are talking to each other, communication is more successful if their brainwaves are in synchrony.

It is a bit like business partners: if one of the two parties changes strategy to keep the business going, the other has to adapt in turn. The leap from business ventures to the structure of proteins might seem a little bold. Yet, this concept of "balanced changes" is precisely the guiding principle of an important new study just appeared in PNAS, the journal of the National Academy of Sciences of the United States.

Attempts by managers to empower staff by delegating different work to them or asking for their opinions can be detrimental for employee productivity, research shows.

Giving employees more authority can have a negative impact on their day to day performance and perhaps give the impression that their boss is just seeking to avoid doing their own work, according to the study.

CHICAGO - Former National Football League (NFL) players are more likely to have enlarged aortas, a condition that may put them at higher risk of aneurysms, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).

Scientists have successfully visualized terahertz radiation, popularly known as T-rays, using a crystal called mayenite (Ca12Al14O33). Their method cleverly utilizes the rattling motion caused by the vibration of oxygen ions inside the cage-like structures of the crystal.

EAST LANSING, Mich. - State laws that restrict gun ownership among domestic abusers and others with violent histories appear to significantly reduce intimate partner homicides, indicates a groundbreaking national study led by a Michigan State University researcher.

The findings, which come on the heels of the Texas church massacre by a man with a history of domestic violence, suggest state laws with broader gun restrictions are more effective at preventing homicides among romantic partners - even if the laws do not exclusively target domestic abuse.

A new method of examining the skin can reduce the number of animal experiments while providing new opportunities to develop pharmaceuticals and cosmetics. Chemical imaging allows all layers of the skin to be seen and the presence of virtually any substance in any part of the skin to be measured with a very high degree of precision.

A University of Bristol-led study has revealed new details about dinosaur feathers and enabled scientists to further refine what is potentially the most accurate depiction of any dinosaur species to date.

Birds are the direct descendants of a group of feathered, carnivorous dinosaurs that, along with true birds, are referred to as paravians - examples of which include the infamous Velociraptor.

The world is entering "a technology-driven Age of Optimization" bringing about more sustainable production, consumption and work in many manifestations and at every scale.

That's the message from international experts meeting in Malaysia at the Global Innovation Summit 2017, the 8th in a series focussed this year on environmental sustainability. The event is organized by the Global Federation of Competitiveness Councils (GFCC) and the Malaysian Industry-Government Group for High Technology (MIGHT).

Some heart disease patients face a higher risk of sudden cardiac death, which can happen when an arrhythmia -- an irregular heartbeat-- disrupts the normal electrical activity in the heart and causes the organ to stop pumping. Arrhythmias linked to sudden cardiac death are very rare, however, making it difficult to study how they occur--and how they might be prevented.
