Researchers have used a soft, wearable robot to help a person living with Parkinson's walk without freezing. The robotic garment, worn around the hips and thighs, gives a gentle push to the hips as the leg swings, helping the patient achieve a longer stride. The device completely eliminated the participant's freezing while walking indoors, allowing them to walk faster and further than they could without the garment's help.
The cycling of water across membrane transporters is an hallmark of the cell metabolism and is potentially of high diagnostic significance for the characterization of tumors and other diseases. A research team has now introduced a new MRI-based method for assessing this water exchange. By this method, they were able to estimate the degree of malignancy and the success of treatments in mice tumor models.
Researchers have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered. They push back the fossil record of thylakoids by 1.2 billion years and provide new information on the evolution of cyanobacteria which played a crucial role in the accumulation of oxygen on the early Earth.
A new study unlocks the secrets of how high blood pressure (hypertension) fuels the progression of arterial disease.
Researchers may have identified the missing component in the chemistry of the Venusian clouds that would explain their color and splotchiness in the UV range, solving a long-standing mystery.
The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fiberglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study conducted on glass nanofibers.
Scientists have created analogs of the antibiotic spectinomycin that are significantly more effective against these highly resistant bacteria.
The objective of the experiment was to assess Polymer Electrolyte Membrane Fuel cell operation in space and to collect data to facilitate the design of systems for future missions.
A plant native to India has been overharvested, pushing it to the endangered list; the researchers say the study could pave the way for effective and efficient commercial production of the drug and reduce the need to cut down endangered plants.
Glass is one of the more magical materials around us: it gives us the illusion of being in an open space even when we are not
In a study designed to better understand sudden, unexpected deaths in young children, which usually occur during sleep, researchers have identified brief seizures, accompanied by muscle convulsions, as a potential cause.
A new study demonstrates that a glucagon-like peptide-1 receptor (GLP-1R) agonist, a member of a class of medication used to treat Type 2 diabetes and obesity, can lead to a rapid improvement in insulin sensitivity.
A pair of proteins could contribute to the development of healthy, strong bones by directing early cell movement and blood vessel generation.
When youth thrive despite difficult circumstances, they are usually lauded for their accomplishments. However, overcoming adversity may have a hidden physiological cost, especially for minority youth. A new study looks at physiological changes among high-striving minority youth in early adolescence.
With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers have drawn inspiration from this natural wonder to develop a technological platform with similar capabilities for use in a variety of fields, including the military, medicine, robotics and sustainable energy.
The dynamic lifecycle of the malaria parasite means that the density of the Plasmodium can suddenly drop below the level of detection in asymptomatic people -- especially when older, less sensitive tests are used. Such fluctuations can make it difficult, when testing only at a single point in time, to determine if an apparently healthy person is in fact infected.
Neptune is fondly known for being a rich blue and Uranus green -- but a new study has revealed that the two ice giants are actually far closer in color than typically thought. The correct shades of the planets have now been confirmed.
Having bipolar disorder -- a serious mental illness that can cause both manic and depressed moods -- can make life more challenging. It also comes with a higher risk of dying early. Now, a study puts into perspective just how large that risk is, and how it compares with other factors that can shorten life.
