A brain-related visual impairment, which until recently was thought to be rare, may affect one in every 30 children according to new research investigating the prevalence of Cerebral Visual Impairment [CVI]. The findings aim to raise awareness of CVI among parents and teachers to help them identify signs of the condition earlier.
A phenomenon called 'oxidative stress' is seen in affected organs during the early stages of certain difficult-to-treat diseases like cancer and kidney dysfunction. Detecting oxidative stress could thus enable early diagnosis and preventive treatments. But, the in vivo measurement of oxidative stress caused by both oxidation and reduction has historically been difficult. Now, scientists have developed an advanced quantum sensor technology that can detect 'oxidative stress' non-invasively throughout the body using fluorescent imaging and MRI.
Scientists have developed a novel method to induce stem cell generation from the blood samples of dogs. Through this technique, the scientists hope to advance regenerative therapies in veterinary medicine. This would mean that, in the near future, veterinarians might be able to reverse conditions in dogs that were previously thought incurable.
Hikers, soldiers and school children all know the burden of a heavy backpack. But now, researchers have developed a prototype that not only makes loads feel about 20% lighter, but also harvests energy from human movements to power small electronics. The new backpack could be especially useful for athletes, explorers and disaster rescuers who work in remote areas without electricity, the researchers say.
Biomedical scientists reports a drug -- an estrogen receptor ligand called indazole chloride (IndCl) -- has the potential to improve vision in patients with multiple sclerosis, or MS. The study was performed on mice induced with a model of MS and the first to investigate IndCl's effect on the pathology and function of the complete afferent visual pathway.
Researchers have identified key variants that help explain the differences between the viruses that cause COVID-19 and Severe Acute Respiratory Syndrome (SARS).
All that's local is a lot more global, and scientists say solutions can only be found through broader views and collaborations nearby and far away.
A 15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at small scales? Its findings also reveal trends related to carbon sequestration and climate change as the Arctic becomes both greener and browner.
There are two main elements to observe when assessing sea level rise. One is the loss of the ice on land and the other is that the sea will expand as it gets warmer. Researchers have constructed a new method of quantifying just how fast the sea will react to warming. Former predictions of sea level have been too conservative, so the sea will likely rise more and faster than previously believed.
The lockdowns and reduced societal activity related to the COVID-19 pandemic affected emissions of pollutants in ways that slightly warmed the planet for several months last year, according to new research. The counterintuitive finding highlights the influence of airborne particles, or aerosols, that block incoming sunlight.
New research has found that optical coherence tomography (OCT) imaging technology can be utilized to distinguish between legitimate and counterfeit travel documents.
Autoimmune diseases, in which the body's own immune system attacks healthy tissue, can be life-threatening and can impact all organs. A research team has now found a possible cause for these self-destructive immune system attacks: a hyperactive RANK protein on the surface of B cells. The research opens the door to new therapeutic possibilities.
Researchers have invented a device that operates at 40 times colder than deep space to directly control thousands of qubits, the building blocks of quantum computers.
A research team confirmed the potential of tactile devices by developing ceramic piezoelectric materials that are three times more deformable. For the fabrication of highly deformable nanomaterials, the research team built a zinc oxide hollow nanostructure using proximity field nanopatterning and atomic layered deposition.
Researchers have discovered a new 'seeding' process in brain cells that could be a cause of dementia and Alzheimer's disease.
One of birdwatching's most commonly held and colorfully named beliefs, the Patagonia Picnic Table Effect, is more a fun myth than a true phenomenon, research suggests.
A team has developed a portable device that produces high-resolution 3D images of human skin within 10 minutes.
