Scientists investigate the influence of Arctic cold air on carbon dioxide uptake of the east sea.

In a new study featuring data from 573,088 people, researchers have found a link between hearing loss and the development of dementia. The study is the largest of its kind to date.

In a scientific breakthrough that aids our understanding of the internal wiring of immune cells, researchers have cracked the code behind IKAROS, an essential protein for immune cell development and protection against pathogens and cancer. This disruptive research is poised to reshape our comprehension of gene control networks and its impact on everything from eye color to cancer susceptibility and design of novel therapies.

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.
