Flour-derived borocarbonitride enriched with boron-oxygen for the oxidative dehydrogenation of propane to olefins
In a study published in the journal Science China Chemistry, catalytic performance was investigated using a fixed-bed reactor and the structure-activity relationship was studied by combining various characterizations with DFT calculations......»»
Deep sea rocks suggest oxygen can be made without photosynthesis, deepening the mystery of life
Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this by photosynthesizing carbon dioxide. However, a recent study demonstrates that oxygen may be produced without th.....»»
New nanocatalyst targets tumors without oxygen
Tumors often contain areas of oxygen-deficient tissue that frequently withstand conventional therapies. This is because the drugs applied in tumors require oxygen to be effective. An international research team has developed a novel mechanism of acti.....»»
Who should get paid for nature"s sequenced genes?
Much of the vanilla that flavors our ice cream today is artificial, derived from the genetic signature of a plant that hundreds of years ago was known only to an Indigenous Mexican tribe......»»
Novel self-cleaning electrode developed for alkaline-earth metal peroxide synthesis
Metal peroxide (MO2, M=Ca, Sr, Ba) is an alternative to hydrogen peroxide (H2O2). It has excellent oxidative properties, superior chemical stability, high purity, and is easy to store and transport. It has been widely used in wastewater treatment and.....»»

Jury rules Masimo smartwatches infringe Apple design patents
Apple and medical device company Masimo are currently embroiled in multiple legal battles, headlined by the ongoing fight over the Apple Watch’s blood oxygen sensor. In a separate case, however, Apple was handed a victory today courtesy of a ju.....»»
Microbes feed on iron: New study reveals how they do it
Pipelines, sprinklers, and other infrastructure in oxygen-free environments are vulnerable to microbially induced corrosion (MIC)—a process where microorganisms degrade iron-based structures, potentially leading to costly damages or even collapses......»»
Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
Shear waves split into fast and slow waves when they travel through elastically anisotropic media, and the anisotropy of the seismic velocity is recorded by seismic stations. In the Earth's deep interior, this is usually interpreted as the effect of.....»»
Specially designed transistors allow researchers to "hear" defects in a promising nanomaterial
An international research team led by NYU Tandon School of Engineering and KAIST (Korea Advanced Institute of Science and Technology) has pioneered a new technique to identify and characterize atomic-scale defects in hexagonal boron nitride (hBN), a.....»»
Satellite-derived data on artificial light at night indicate rapidly increasing industrial activities in the Arctic
More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urb.....»»
Evolution in action: How ethnic Tibetan women thrive in thin oxygen at high altitudes
Breathing thin air at extreme altitudes presents a significant challenge—there's simply less oxygen with every lungful. Yet, for more than 10,000 years, Tibetan women living on the high Tibetan Plateau have not only survived but thrived in that env.....»»
Research provides molecular insights into sexual dimorphism of chicken feathers
Birds possess unique skin appendages called feathers that are derived from the outermost layer of skin cells. Feathers are important for several functions, such as flight, temperature regulation, protection from external stimuli, and mating behavior......»»
New method for measuring luminescence lifetime offers versatility in scientific imaging
Oxygen is a key molecule for life, and in order to understand ecosystem dynamics it can be important to follow its ways in much detail. Optical sensors that use luminescent dyes have long been used to map oxygen levels in marine systems. Oxygen reduc.....»»
Reoxygenating oceans: Startups lead the way in Baltic Sea
European scientists have teamed up with two startups in a pioneering experiment to tackle one of the major problems facing sea life—the depletion of oxygen in the ocean, causing the disappearance of fish and marine biodiversity......»»
Oxidative stress: How protein recycling protects against cell death
Researchers at LMU University Hospital have discovered a new molecular switch that protects against cell death......»»
Novel detection technology alerts health risks from TNT metabolites
Recently, a research group from the Hefei lnstitutes of Physical Science (HFIPS) of the Chinese Academy of Sciences developed an approach that can facilitate rapid detection of both positive and negative ions of four toxic metabolites derived from 2,.....»»
Team discovers three new magnetic and helium-enriched hot subdwarf stars
An international team of astronomers reports the discovery of three new helium-enriched hot subdwarf stars with strong magnetic fields. The finding, made with the Southern African Large Telescope (SALT), is detailed in a research paper published Oct......»»
Team presents new theoretical strategy for generating asymmetric distributions in probability and statistics
As is well known, the normal distribution is a key tool in probability and statistics. It can be described as a distribution that obeys a universal rule derived from one of the most important theorems in probability: the central limit theorem, often.....»»
Low stream diatom biodiversity potentially decreases stream oxygen production in remote islands
Benthic diatoms are the most important and biodiverse primary producers in streams and comprise the basis for the food webs, fueling animals such as insects and stream fishes including trout......»»
Why PFAS-enriched foam is forming on some of the cleanest lakes in the country
A curious phenomenon springs up occasionally on New York's Finger Lakes: white foam, sometimes in miles-long swathes, almost as if a massive washing machine emptied out into the water......»»
