WASHINGTON, January 28, 2020 -- Small magnetic objects, which have been used successfully in technological applications such as data storage, are showing promise in the biomedical field. Magnetic nanostructures have interesting properties that enhance novel applications in medical diagnosis and allow the exploration of new therapeutic techniques.
WASHINGTON, January 28, 2020 -- Amyloids are aggregates consisting of stacks of thousands of proteins bound tightly together. Their formation is involved in several widespread disorders, including Alzheimer's disease and Type II diabetes.
In this week's Journal of Chemical Physics, by AIP Publishing, scientists report on a mathematical model for the formation of amyloid fibrils. The model sheds light on how the aggregation process can occur in a catalytic manner, something that has not been previously well understood.
WASHINGTON, January 28, 2020 -- Since the Industrial Revolution, the environmental impacts of energy have posed a concern. Recently, this has driven researchers to search for viable options for clean and renewable energy sources.
Due to its affordability and environmental friendliness, hydrogen is a feasible alternative to fossil fuels for energy applications. However, due to its low density, hydrogen is difficult to transport efficiently, and many on-board hydrogen generation methods are slow and energy intensive.
New York, NY--January 28, 2020--A new study from Columbia Engineering and Harvard identified the critical physiological importance of suitable temperatures for butterfly wings to function properly, and discovered that the insects exquisitely regulate their wing temperatures through both structural and behavioral adaptations.
Eating walnuts may help slow cognitive decline in at-risk groups of the elderly population, according to a study conducted by researchers in California and Spain.
Surveys show that consumers are worried that smart speakers are eavesdropping on their conversations and day-to-day lives. Now University of British Columbia researchers have found that people are also concerned about something else: friends, family and others who may have access to these devices.
Hologram techniques are already used in our everyday life. A hologram sticker to prevent from counterfeiting money, Augmented Reality navigation projected in front mirror of a car to guide directions, and Virtual Reality game that allows a user to play in a virtual world with a feeling of live are just a few examples to mention. Recently, thinner and lighter meta-hologram operating in forward and backward directions has been developed.
Hives afflict 1 in 5 people, but the exact mechanisms behind the itchy red rashes are not well known.
The research team studied the patterns of hives in patients and reproduced the hive patterns using a mathematical model called a reaction-diffusion model, a common prototype for understanding how patterns develop. The researchers' model is a single equation type which had never before been used to generate complex patterns.
Drug-coated iron nanowires that can be guided to the site of a tumor using an external magnetic field before activating a three-step cancer-killing mechanism could provide an effective option for cancer therapy.
Co-developed by KAUST researchers, these nanowires release their drug cargo inside cancer cells, while also punching holes in the cell's membrane and delivering a blast of heat. While the combination therapy maximizes cancer cell death, its highly targeted nature should minimize side effects.
Research by a University of Georgia psychologist shows that targeting one particular symptom of schizophrenia has a positive effect on other symptoms, offering significant promise for treating an aspect of schizophrenia that currently has no pharmaceutical options.
All plants and animals need suitable conditions to survive. That means a certain amount of light, a tolerable temperature range, and access to sources of food, water and shelter.
Many of the existing efforts to protect plant and animal species across the United States rely on information about where these species currently live. For example, if a rare bird species such as the snowy plover is found in a specific location along the Washington coast, conservationists try to protect it from human development where it lives.
Earthquakes along a complex series of faults in the upper plate of New Zealand's northern Hikurangi Subduction Margin were responsible for coastal uplift in the region, according to a new evaluation of local marine terraces.
The findings, reported in the Bulletin of the Seismological Society of America, could shape new evaluations of seismic hazard in New Zealand. They suggest that earthquakes rupturing multiple faults may contribute more than subduction earthquakes to damaging uplift in the area.
GAINESVILLE, Fla. --- The Bahamian hutia, a large Caribbean rodent with a blissed-out disposition, presents a curious case study in how human food preferences can drive biodiversity, sometimes shaping it over 1,000 years.
Michigan State University and Stanford University scientists have invented a nanoparticle that eats away - from the inside out - portions of plaques that cause heart attacks.
Bryan Smith, associate professor of biomedical engineering at MSU, and a team of scientists created a "Trojan Horse" nanoparticle that can be directed to eat debris, reducing and stabilizing plaque. The discovery could be a potential treatment for atherosclerosis, a leading cause of death in the United States.
Approximately twice as much methane is seeping into the atmosphere than the Environmental Protection Agency estimates from oil and gas facilities in the south central U.S., according to a series of measurements taken by meteorologists using NASA aircraft.
