New sensing technologies to study elusive flying bats

How can we understand the activity of wild bats? Mostly soundless, flying in the dark, bats feed at night and evade our senses. Many bats can use echolocation to hunt and can avoid the traditional nets used to capture them; those that do not "echolocate" cannot be detected by ultrasound bat detectors. Now, an international research team led by the University of Göttingen has developed a new...

CMS collaboration homes in on Higgs boson's lifetime

The Higgs boson doesn't stick around for long. Once it is created in particle collisions, the famed particle lives for a mere less than a trillionth of a billionth of a second or, more precisely, 1.6 x 10-22 seconds. According to theory, that is, for so far experiments have only been able to set bounds on the value of the particle's lifetime or to determine this property with a large uncertainty....

Making your website stickier: The role of customer value, satisfaction, trust and habit

A competitor is usually just one click away, so how to companies make their websites stickier and so retain their potential buyers and persuade them to make a purchase? Writing in the International Journal of Technology Marketing, a team from India has investigated the role of customer values, satisfaction, trust, and habits and how those characteristics related to their sticking with a given...

Host and resident bacteria join forces to control fungi in plant roots

In nature, the roots of healthy plants are colonized by complex microbial communities of bacteria and filamentous eukaryotes (i.e., fungi and oomycetes, Fig. 1), the composition of which profoundly influences plant health. Maintaining a microbial equilibrium in their roots is very important for plants to remain healthy, however, the means by which this is achieved by plants is still largely...

Artificial material protects light states on smallest length scales

Light not only plays a key role as an information carrier for optical computer chips, particularly for the next generation of quantum computers. Its lossless guidance around sharp corners on tiny chips and the precise control of its interaction with other light are the focus of research worldwide. Scientists at Paderborn University have now demonstrated the spatial confinement of a light wave to a...

Africa alerted the world to Omicron. Why are we now the pariahs? | Ayoade Olatunbosun-Alakija

Rich nations are again raising barriers to ending the pandemic – politicians, globally, must follow the science and act togetherDr Ayoade Olatunbosun-Alakija is the co-chair of the African Union’s Africa Vaccine Delivery AllianceThe advent of the Omicron variant has given us a glimpse of an alternative future in which, had the Sars-CoV-2 virus been initially identified in Africa in early 2020,...

Can seven questions determine how wise you are?

Researchers report that an abbreviated, seven-item scale can help determine with high validity a person's level of wisdom, a potentially modifiable personality trait that has been shown to have a strong association to well-being.

Elevated heart rate linked to increased risk of dementia

Having an elevated resting heart rate in old age may be an independent risk factor of dementia, according to a new study. Since resting heart rate is easy to measure and can be lowered through exercise or medical treatment, the researchers believe that it may help to identify people with higher dementia risk for early intervention.

Egg-carton-style patterning keeps charged nanoparticles in place and suitable for a wide range of applications

Researchers at the University of Michigan and Seoul National University of Science and Technology have devised a new method for manufacturing devices that require precisely sized and positioned micro- and nanoscale particles. The technique is suitable for a wide array of assembly of micro- and nanoscale objects, and useful for electronic devices, and biological applications.

Novel two-step mechanism revealed in two-dimensional material formation

Typically only an atom thick, 2D materials exhibit highly desirable properties for advanced technologies, such as flexibility, superconductivity and more. Made from carefully transitioning individual components from gas or vapor to crystalline solids, such materials and the mechanisms by which they become imbued with such characteristics are still shrouded in mystery.
