Electromagnetic (EM) waves and gravitational waves are the only available means to study the Universe on a large scale. For millennia, only the former could be used, in naked-eye astronomical observations by the ancients based on the reception of visible light, or present-day super telescopes operating in various bands of the EM spectrum, from radio waves to gamma rays.
Research can contribute to earlier diagnosis of diabetic neuropathy
Research conducted at Cruzeiro do Sul University in São Paulo, Brazil, can contribute to earlier diagnosis of diabetic neuropathy, a disorder characterized by damage to peripheral nerves, with symptoms such as pain and paresthesia (pricking, burning and numbness), mainly in the legs and feet.
In the study, a group led by Professor Paulo Barbosa de Freitas Júnior measured grip force in diabetic patients while they were holding and handling objects. The results were compared with data for healthy subjects and patients with other neurological diseases, such as multiple sclerosis, Parkinson s, and carpal tunnel syndrome (pain, numbness and tingling in the hand and arm caused by a pinched nerve in the wrist).
