The tightly defined ratios of metals in MOFs makes them ideal starting materials for novel catalyst creation.
Heating bimetallic metal organic frameworks (MOFs) until their porous structure collapses into nanoparticles can be a highly effective way to make catalysts. This novel approach to catalyst design has now been used by KAUST and Spanish researchers to make a robust catalyst that converts carbon dioxide (CO2) into carbon monoxide (CO) gas with unprecedented selectivity.
Published today in Nature Communications, the team from the Peter Doherty Institute for Infection and Immunity (Doherty Institute), Alfred Health and Monash University sought to understand which patients would recover quickly from influenza and which would become severely ill.
A group of researchers from Osaka University developed a quadruped robot platform that can reproduce the neuromuscular dynamics of animals (Figure 1), discovering that a steady gait and experimental behaviors of walking cats emerged from the reflex circuit in walking experiments on this robot. Their research results were published in Frontiers in Neurorobotics.
Dr. HAN Fangpu's group from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences reports the identification and functional study of the maize Knl1 gene in an article published online in PNAS. The gene is a major component of the KMN network that links centromeric DNA and the plus-ends of spindle microtubules. It also plays an important role in kinetochore protein recruitment.
Quantum mechanics can be used to create more stable and more easily produced organic solar cells. These are the findings of new research from the University of Gothenburg.
The Sturtian Snowball Earth glaciation (717~660 million years ago) represents the most severe icehouse climate in Earth's history. Geological evidence indicates that, during this glaciation, ice sheets extended to low latitudes, and model simulations suggest global frozen ocean as well as a prolonged shut-down of the hydrological cycles.
A new study from the University of Surrey has revealed 'real world' factors that influence people's interest in adopting a dietary pattern called time-restricted feeding.
According to NHS England, 67 per cent of men and 60 per cent of women in the UK are overweight or obese - with more than 11,000 yearly hospital admissions directly attributable to obesity.
Time-restricted feeding, which is a type of intermittent fasting, is the practice of restricting the time between the first and last food intake each day - therefore prolonging the daily fasting period.
Teamwork is becoming increasingly common in modern science. In this context, the effect of different characteristics of a team on its research performance has been studied extensively. Various factors such as team size, number of countries involved, universities, disciplines, and workload distribution have been found to have a significant contribution on the paper's role in advancing science.
Numerous disease development processes are linked to epigenetic modulation. One protein involved in the process of modulation and identified as an important cancer marker is BRD4. A recent study by the research group of Giulio Superti-Furga, Principal Investigator and Scientific Director at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, now shows that the supply of purines as well as the purine synthesis of a cell can influence BRD4 activity and thus play a role in the carcinogenesis process.
Despite the rapid and significant changes in consumption patterns witnessed during the initial months of the COVID-19 pandemic, Japanese households maintained their normal levels of greenhouse gases emissions. The "anthropause" -- reduction of human activity due to the pandemic -- made headlines last summer, but factory shutdowns and broken global supply chains did not translate into the adoption of eco-friendly lifestyles for the average household.
Cerebral aneurysms are malformations caused by abnormalities on the walls of blood vessels in the brain. When these blood vessels rupture, about 30% of the sufferers die on the spot, giving these the rightful label of 'ticking bombs in the head'. Recently, a research team at POSTECH has come up with a new treatment that can disassemble these time bombs by filling the aneurysm in blood with a new method.
The skin, which covers the surface of the human body, is its largest organ. It is the first organ to show changes stemming from organ or physiological activity. It is especially common for diabetic patients to suffer from skin diseases or infections. Recently, a POSTECH research team has succeeded in creating a 3D artificial skin that enables observation of skin diseases of diabetic patients.
A new study published in The Lancet Infectious Diseases journal has found that the risk of delayed acute complications after non-hospitalised SARS-CoV-2 infection is low, but persistent symptoms in this group could lead to increased visits to general practitioners or outpatient clinics in the six months following infection. The study assessed only those complications that led to contact with hospitals.
Due to the chaotic nature of the atmosphere, weather forecasts, even with ever improving numerical weather prediction models, eventually lose all skill. Meteorologists have a strong desire to better understand this process as they try to trace forecast error back to observational gaps and to provide a means for improvement.
A pioneering study by UCL scientists has discovered the presence of a harmful inflammatory protein in patients with symptomatic tuberculosis (TB).
Researchers say, by targeting the IL-17 cytokine, a component produced naturally by the immune system in response to infection, excessive and damaging lung inflammation caused by TB may be significantly reduced to help speed up patient recovery.
