Metal-air batteries have been pursued as a successor to lithium-ion batteries due to their exceptional gravimetric energy densities. They could potentially enable electric cars to travel a thousand miles or more on a single charge.
The movie Finding Nemo could have a much darker sequel - as artificial light in coral reefs leaves the famous fish unable to reproduce offspring, according to a new study.
Results by Flinders University and the University of Melbourne published in Biology Letters show an increasing amount of artificial light at night (ALAN) in coral reefs, even at relatively low levels, masks natural cues which trigger clownfish eggs to hatch after dusk.
Platelet cells, which prevent mammals from bleeding non-stop, first evolved around 300 million years ago in an egg-laying animal similar to the modern duck-billed platypus, finds joint research by UCL and Yale University.
This event was a prerequisite for the origin of placental development in mammals, including human beings.
DALLAS, July 10, 2019 -- African American children living in socioeconomically disadvantaged neighborhoods are significantly less likely than their Caucasian counterparts in disadvantaged or wealthier areas to receive CPR from a bystander, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
Did you know that 90% of cancer patients die from distant metastasis? The latter occurs when cancer cells have the ability to move within the patient's body and invade its healthy tissues. In a study published in Nature Communications, researchers from the University of Montreal Hospital Research Centre (CRCHUM) have shown the key role that a protein called Ran plays in the mobility of ovarian cancer cells. They demonstrated these cells cannot migrate from cancerous sites without the help of Ran.
Data from the Morris Animal Foundation Golden Retriever Lifetime Study shows that inbreeding depression, the result of breeding closely-related individuals, reduces litter sizes in purebred golden retrievers.
RIVERSIDE, Calif. -- Move aside, electrons; it's time to make way for the trion.
A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor -- ultraclean single-layer tungsten diselenide (WSe2) -- a feat that could increase the capacity and alter the form of information transmission.
Researchers from the NASA Jet Propulsion Laboratory (JPL) and the University of Bath have developed a satellite-based early warning system that could spot tiny movements in bridges that indicate they could collapse.
Combining data from a new generation of satellites with a sophisticated algorithm, the monitoring system could be used by governments or developers to act as a warning system ensuring large-scale infrastructure projects are safe.
Many different countries have a tea culture, and Japanese Matcha tea is growing in popularity around the world. In Japan, Matcha has a long history of being used for various medicinal purposes. It has been suspected to have various beneficial effects to health, but relatively little scientific evidence supported that claim. Now, a group of Japanese researchers from Kumamoto University has shown that anxious behavior in mice is reduced after consuming Matcha powder or Matcha extract.
With the maturing of the perovskite solar cells (PSCs) technology, it is highly desirable to develop colorful solar cells to satisfy the requirements of aesthetic purposes in applications including building integrated photovoltaics and wearable electronics. The broad optical absorption and the large absorption coefficient of perovskites normally lead to high-efficiency cells with dark-brown colors. Till now, two representative approaches have been used to achieve colorful PSCs: (1) bandgap engineering and (2) structural colors.
(Philadelphia, PA) - Like a sorting machine in an assembly line, a molecule known as VPS35 detects and removes defective proteins from neurons. And similar to other quality control processes, the VPS35 system goes a long way toward protecting health, according to new work by researchers at the Lewis Katz School of Medicine at Temple University. They show for the first time that VPS35 clears the brain of a potentially harmful protein called tau, which otherwise accumulates and contributes to neurodegenerative disorders, including Alzheimer's disease.
The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, telecommunications and medical diagnostics. A theory from 2006 predicts that it should be possible to use graphene - a monoatomic layer of carbon atoms- in a magnetic field not only to absorb terahertz and infrared light on demand but also to control the direction of the circular polarisation.
Manuel Eichelberger and Simon Tanner, two ETH doctoral students, store data in music. This means, for example, that background music can contain the access data for the local Wi-Fi network, and a mobile phone's built-in microphone can receive this data. "That would be handy in a hotel room," Tanner says, "since guests would get access to the hotel Wi-Fi without having to enter a password on their device."
For the first time, a team there has investigated the fundamental photochemical processes around the metal atom and its ligands. The study has now been published in "Angewandte Chemie, International Edition" and is displayed on the cover.
A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms. A team led by Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna report for the first time rare microbial-tungsten interactions at the nanometer range. Based on these findings, not only the tungsten biogeochemistry, but also the survivability of microorganisms in outer space conditions can be investigated.
