Injecting sulphur into the stratosphere to reduce solar radiation and stop the Greenland ice cap from melting. An interesting scenario, but not without risks. Climatologists from the University of Liège have looked into the matter and have tested one of the scenarios put forward using the MAR climate model developed at the University of Liège. The results are mixed and have been published in the journal The Cryosphere.
ITHACA, N.Y. - An interdisciplinary team of Cornell and Harvard University researchers developed a machine learning tool to parse quantum matter and make crucial distinctions in the data, an approach that will help scientists unravel the most confounding phenomena in the subatomic realm.
The Cornell-led project's paper, "Correlator Convolutional Neural Networks as an Interpretable Architecture for Image-like Quantum Matter Data," published June 23 in Nature Communications. The lead author is doctoral student Cole Miles.
When gravitational waves were first detected in 2015 by the advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), they sent a ripple through the scientific community, as they confirmed another of Einstein’s theories and marked the birth of gravitational wave astronomy. Five years later, numerous gravitational wave sources have been detected, including the first observation of two colliding neutron stars in gravitational and electromagnetic waves.
If a virtual world has ever left you feeling nauseous or disorientated, you're familiar with cybersickness, and you're hardly alone. The intensity of virtual reality (VR)--whether that's standing on the edge of a waterfall in Yosemite or engaging in tank combat with your friends--creates a stomach-churning challenge for 30-80% of users.
Although wastewater disposal has been the primary driving force behind increased earthquake activity in southern Kansas since 2013, a new study concludes that the disposal has not significantly changed the orientation of stress in the Earth's crust in the region.
Activities like wastewater disposal can alter pore pressure, shape and size within rock layers, in ways that cause nearby faults to fail during an earthquake. These effects are thought to be behind most recent induced earthquakes in the central and eastern United States.
Five years ago, researchers at Northwestern University made international headlines when they discovered that human eggs, when fertilized by sperm, release billions of zinc ions, dubbed “zinc sparks.”
Software to help towns and cities use street-planting to reduce citizens' exposure to air pollution has been developed by researchers at the University of Birmingham.
Street planting, or 'green infrastructure', is an essential part of the urban realm, but there is a misconception that plants remove or 'soak up' a lot of pollution. Instead, planting at this scale primarily serves to redistribute pollution by changing air currents within streets and beside open roads.
Recently, a research team led by Prof. KONG Lingtao at the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) has prepared a type of hollow amorphous Co/C composites to activate hydrogen peroxide (H2O2) to generate singlet oxygen, achieving selective elimination of oxytetracycline (OTC) in complicated water matrices. The relevant results was published in Chemical Engineering Journal.
Ishikawa, Japan - Many researchers in the field of materials science constantly seek novel and versatile platforms that can be used to tailor materials to match their intended use. One example of this are covalent organic frameworks (COFs), an emerging class of crystalline porous polymers with a favorable set of fundamental properties, namely crystallinity, stability, and porosity. This combination makes them, in theory, adjustable to many modern applications.
A new nanotechnology development by an international research team led by Tel Aviv University researchers will make it possible to generate electric currents and voltage within the human body through the activation of various organs (mechanical force). The researchers explain that the development involves a new and very strong biological material, similar to collagen, which is non-toxic and causes no harm to the body's tissues.
Recently, with the help of a steady-state strong magnetic field experimental device, scientists constructed nano-scale borate bioactive glass (Nano-HCA@BG), which can effectively reduce the biological toxicity of borate bioglass, improve the biocompatibility of the glass, and promote the effect of borate bioglass on skin repair.
However, the majority of these organisms are believed to be in a state a state of 'dormancy' due to environmental stress, such as nutrient-poor conditions. An international team of scientists led by Dagmar Woebken and Stephanie A. Eichorst from the University of Vienna investigated how acidobacteria, which are widespread in soils, can survive under adverse conditions. Two recent studies published in The ISME Journal and mSystems describe these survival strategies.
Medical researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have uncovered how signal proteins of the immune system regulate the development of atherosclerosis.
Researchers from Skoltech and the Mental Health Research Center have found 22 lipids in the blood plasma of people with schizophrenia that were associated with lower symptom improvement over time during treatment. These can help track resistance to medication that affects over a third of patients. The paper was published in the journal Biomolecules.
Announcing a new article publication for BIO Integration journal. In this article the authors Xiao'en Shi, Xu Zhang, Xinlu Zhang, Haizhen Guo and Sheng Wang from Tianjin University, Tianjin, China discuss the integration of reactive oxygen species generation and prodrug activation for cancer therapy.
