Newly discovered 'design rule' brings nature-inspired nanostructures one step closer

Scientists aspire to build nanostructures that mimic the complexity and function of nature's proteins, but are made of durable and synthetic materials. These microscopic widgets could be customized into incredibly sensitive chemical detectors or long-lasting catalysts, to name a few possible applications.

New research shows candle soot can power the lithium batteries in electric cars

Architecture-inspired nanostructures enable perfect optical metasurfaces

Optical devices are critical in diverse military and civil applications, whereas traditional optical devices are bulky and heavy because they rely on the phase accumulation on a long optical path. In an article published in Science Advances, Prof. Xiangang Luo from the Chinese Academy of Sciences and co-workers have now demonstrated that ultrathin and lightweight optical devices could be constructed using nanostructures catenaries, which were typically used in architecture to construct incredible bridges and arches.

Physics news

The topolariton, a new half-matter, half-light particle

A new type of "quasiparticle" theorized by Caltech's Gil Refael, a professor of theoretical physics and condensed matter theory, could help improve the efficiency of a wide range of photonic devices—technologies, such as optical amplifiers, solar photovoltaic cells, and even barcode scanners, which create, manipulate, or detect light.

Scandium trifluoride shrinks when warm, lends understanding of volume-changing materials

Most materials swell when they warm, and shrink when they cool. But UConn physicist Jason Hancock has been investigating a substance that responds in reverse: it shrinks when it warms.

Perfectly accurate clocks turn out to be impossible

Can the passage of time be measured precisely, always and everywhere? The answer will upset many watchmakers. A team of physicists from the universities of Warsaw and Nottingham have just shown that when we are dealing with very large accelerations, no clock will actually be able to show the real passage of time, known as "proper time".

Professor solves 140-year fluid mechanics enigma

A Purdue University researcher has solved a 140-year-old enigma in fluid mechanics: Why does a simple formula describe the seemingly complex physics for the behavior of elliptical particles moving through fluid?

New microscopy technology augments surgeon's view for greater accuracy

Researchers at the University of Arizona (UA) have developed a prototype of a new microscope technology that could help surgeons work with a greater degree of accuracy.

Everyone has their own daily rhythm of digital activity, shows study

Over the past decade, there has been a surge of scientific studies on the digital activity of people, such as making mobile calls, texting, e-mailing, and posting on social media. Because nearly all human behavior leaves a digital footprint, scientists can use such digital activity as a proxy to track human activity in general, for example to study differences between cultures or communities in sleep patterns, work schedules, and leisure activities.

Towards the development of a new evaluation method of semiconductors by using terahertz waves

Wide-gap semiconductors such as gallium nitride (GaN) are widely used for optical devices such as blue LED and are also anticipated as materials for next-generation energy saving power devices and solar cells. However, the quality of GaN crystals does not come up to that of conventional semiconductor materials such as silicon (Si) and this prevents GaN from being used for power devices.

Earth news

New study indicates Earth's inner core was formed 1 - 1.5 billion years ago

There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth's inner core was formed 1 - 1.5 billion years ago as it "froze" from the surrounding molten iron outer core.

Predictable ecosystems may be more fragile

When it comes to using our natural resources, human beings want to know what we're going to get. We expect clean water every time we turn on the tap; beaches free of algae and bacteria; and robust harvests of crops, fish and fuel year after year. As a result, we try to manage the use of our resources in a way that minimizes their variability.

Distinguishing coincidence from causality: Connections in the climate system

Detecting how changes in one spot on Earth - in temperature, rain, wind - are linked to changes in another, far away area is key to assessing climate risks. Scientists now developed a new technique of finding out if one change can cause another change or not, and which regions are important gateways for such teleconnections. They use advanced mathematical tools for an unprecedented analysis of data from thousands of air pressure measurements. The method now published in Nature Communications can be applied to assess geoengineering impacts as well as global effects of local extreme weather events, and can potentially also be applied to the diffusion of disturbances in financial markets, or the human brain.

Climate-linked insurance a boon for poor farmers

Poor farmers the world over are increasingly falling prey to natural disasters, droughts and torrential rain largely due to climate change. But there is some good news as well.

Water poses challenge to major cities

Too much water, too little water, or contaminated water. Cities around the world are facing major water-related challenges. These challenges are further aggravated by global trends such as urbanization and climate change. The time has come for water to become an asset rather than a problem in 'smart liveable cities' of the future.

End to contaminated drinking water

As things stand, a suspected contamination of drinking water requires that a technician first be sent out to take samples from the water supply. The samples are then cultured and analysed in the laboratory. Only after several days does it become clear whether the water is contaminated and which bacterium is the offender.

Zebra finches change their call communication pattern in groups according to their reproductive status

The vocal repertoire of songbirds not only consists of complex song which is mainly uttered in the breeding season but is complemented by a large number of simpler calls. Their function however is still poorly understood. Scientists from the Max Planck Institute for Ornithology in Seewiesen in Germany now recorded the calls of individual zebra finches behaving freely inside groups, and found that the birds change their call repertoire and calling behaviour in the group over the course of the breeding cycle. Using tiny microphone transmitters they discovered perfectly timed patterns of call communication that were associated with successful egg-laying.

Researchers find genetic defences of bacteria don't aid antibiotic resistance

When bacteria are exposed to antibiotics, they alter the expression of a number of genes within their genome. One of these responses, known as the SOS response, results in an increase in the rate of DNA mutation. Given that DNA mutation is a fundamental trait of evolution, many people have speculated that the stimulation of this response helps contribute to the increased resistance to antibiotics in bacteria over time.

Medical diagnosis: Will brain palpation soon be possible?

If there is one technique used by the physician to explore the human body during every medical examination in order to make a diagnosis or prescribe further tests, it is palpation. By its nature, however, the brain cannot be palpated without using a highly invasive procedure (craniotomy, or opening the skull), which is limited to rare cases. By drawing on seismology, Inserm researchers led by Stéfan Catheline (Inserm Unit 1032, "Therapeutic Applications of Ultrasound") have just developed a noninvasive brain imaging method using MRI that provides the same information as physical palpation. Ultimately, it could be used in the early diagnosis of brain tumours or Alzheimer's disease. This work is published in PNAS.
