Does nanoconfinement affect the interaction between two materials placed in contact?

Jun 07 2018 - 00:06
Does nanoconfinement affect the interaction between two materials placedin contact?A research team from the ULB shows that it is possible to estimate how nanoconfinement affects the number of contacts formed by two materials placed in intimate contact and, hence, the interfacial interactions.

Dark inflation opens up a gravitational window onto the first moments after the Big Bang

Jun 07 2018 - 00:06
Dark matter and dark energy may have driven inflation, the exponential expansion of the Universe moments after the Big Bang. A new cosmological model proposed by physicists at the University of Warsaw, which takes dark inflation into account, is the first to outline a precise chronology of the main events during the early history of our Universe. The model makes a spectacular prediction: that it should be possible to detect gravitational waves that were formed just fractions of a second after the creation of spacetime.

Bad news becomes hysteria in crowds, new research shows

Jun 07 2018 - 00:06
News stories about terrorism, disease outbreaks, natural disasters, and other potential threats become increasingly negative, inaccurate and hysterical when passed from person to person, according to new research by the University of Warwick.

Scientists use 4D scanning to predict behavior of volcanoes

Jun 07 2018 - 00:06
Scientists are using the latest in 4D technology to predict the behavior of lava flows and its implications for volcanic eruptions. The results explain why some lava flows can cover kilometers in just a few hours, whilst others travel more slowly during an eruption, highlighting the hazard posed by fast-moving flows which often pose the most danger to civilian populations close to volcanoes.

Rescuing historic climate data in the East Asian region

Jun 07 2018 - 00:06
An international team from the UK, China, Japan and the US tackles the challenges of recovering, collating, digitizing and working with long-term instrumental weather observations in in the East Asian Region.

Sharing spaces: Your brain considers other people's personal space as your own

Jun 07 2018 - 00:06
Peripersonal space (PPS) is the area immediately around your body used when interacting with people and objects. Recently, researchers have shown that some neurons in the primate brain respond to an infringement of another individual's PPS as if their own space was being encroached upon. Now, a Japanese researcher studying human behavior has shown that people respond to someone else's PPS as quickly as they do their own.

Cost and scale of field trials for bovine TB vaccine may make them unfeasible

Jun 07 2018 - 00:06
Field trials for a vaccination to protect cattle against bovine tuberculosis (bovine TB) would need to involve 500 herds -- potentially as many as 75,000-100,000 cattle -- to demonstrate cost effectiveness for farmers, concludes a study published today in the journal eLife.

Using mathematical approaches to optimally manage public debt

Jun 07 2018 - 00:06
Large government debt negatively impacts long-term economic growth and the debt-to-gross domestic product (GDP) ratio is an important indicator of a country's financial leverage. In a paper publishing next week in the SIAM Journal on Control and Optimization, financial mathematician Giorgio Ferrari proposes a mathematical model that helps optimize and control the debt-to-GDP ratio.

Study: Larger sample sizes needed to increase reproducibility in neuroscience studies

Jun 07 2018 - 00:06
Small sample sizes in studies using functional MRI to investigate brain connectivity and function are common in neuroscience, despite years of warnings that such studies likely lack sufficient statistical power. A new analysis reveals that task-based fMRI experiments involving typical sample sizes of about 30 participants are only modestly replicable. This means that independent efforts to repeat the experiments are as likely to challenge as to confirm the original results.

Deadly behavior-modifying weapon identified in insect-world chemical arms race

Jun 07 2018 - 00:06
New research from the University of East Anglia joins the dots between zombie ants, an insect-world arms race and the search for new antibiotics. Scientists probing one of the mysteries of the insect world identified a powerful chemical weapon used in the arms race between fungus-farming leafcutter ants and the parasites that plague them. It is hoped that the findings will help scientists search for new antibiotics from this unique battlefield.

Dolphins deliberately killed for use as bait in global fisheries

Jun 07 2018 - 00:06
Ahead of World Oceans Day, new research exposes the practice of killing of aquatic mammals, including some listed as endangered, for the express purpose of securing bait for global fisheries. The practice is widespread globally, but most common in Latin America and Asia. The study reveals there is little information on the impact of this harvesting on targeted mammal populations and urges increased monitoring.
