Scientists have created a sensor based on graphene, which monitors and helps to fight asthma and other respiratory diseases, Zee News reports. The sensor will identify an asthmatic attack at the early stage thereby preventing hospitalization and even death. The idea is that a person with a lung disease will carry the sensor on his neck or wrist. Another option - a person will periodically blow into the device to predict the onset of asthma attack.

According to scientists, complex and long-term tests involving blood sampling will soon disappear. According to Zee News, an inexpensive disposable sensor was introduced. This sensor helps to make a diagnosis by people's breathing. The sensor is able to identify the markers of various diseases in the breath.

A local suppression of thyroid hormone (thyroid hormone) receptor activity in the retina is an unexpected solution that allows to protect the retina from degenerative diseases. According to News-medical.net, the suppression makes it possible to save photoreceptor cells. These cells can be found in the back of the eye. They are responsible for light stimulation and sensitivity to light.

Specialists have designed a nasal spray to deliver medicinal preparations to the brain. It successfully passes through the blood-brain barrier. The spray is not dangerous for healthy tissues. The scientists say that the spray can be used in the treatment of various diseases, for example, brain cancer, "Dni24" reports.
