A new outbreak of a rare but preventable eye infection that can cause blindness, has been identified in contact lens wearers in a new study led by UCL and Moorfields Eye Hospital researchers. The research team found a threefold increase in Acanthamoeba keratitis since 2011 in South-East England. Reusable contact lens wearers with the eye

Zombie cells are the ones that can’t die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. And with a new letter in Nature, Mayo Clinic researchers have expanded that list. In a mouse model of brain disease, scientists

The world needs to keep global temperatures in check by meeting the goals set out in the Paris Agreement, or more people could die because of extreme temperatures, say authors of a new study in the letters section of Springer’s journal Climatic Change. The Paris Agreement, adopted in 2015 under the auspices of the United

While bacteria that produce electricity have been found in exotic environments like mines and the bottoms of lakes, scientists have missed a source closer to home: the human gut. University of California, Berkeley, scientists discovered that a common diarrhea-causing bacterium, Listeria monocytogenes, produces electricity using an entirely different technique from known electrogenic bacteria, and that

Engineers at the University of British Columbia have developed a new ultrasound transducer, or probe, that could dramatically lower the cost of ultrasound scanners to as little as $100. Their patent-pending innovation — no bigger than a Band-Aid — is portable, wearable and can be powered by a smartphone. Conventional ultrasound scanners use piezoelectric crystals

Someday doctors may prescribe sugar pills for certain chronic pain patients based on their brain anatomy and psychology. And the pills will reduce their pain as effectively as any powerful drug on the market, according to new research. Northwestern Medicine scientists have shown they can reliably predict which chronic pain patients will respond to a

Researchers at Karolinska Institutet in Sweden have identified four types of neurons in the peripheral auditory system, three of which are new to science. The analysis of these cells can lead to new therapies for various kinds of hearing disorders, such as tinnitus and age-related hearing loss. The study is published in Nature Communications. When

Ever wonder why flat earthers, birthers, climate change and Holocaust deniers stick to their beliefs in the face of overwhelming evidence to the contrary? New findings from researchers at the University of California, Berkeley, suggest that feedback, rather than hard evidence, boosts people’s sense of certainty when learning new things or trying to tell right

Writing in the current online issue of the journal Stem Cells and Development, researchers at University of California San Diego School of Medicine describe development of a rapid, cost-effective method to create human cortical organoids directly from primary cells. Experimental studies of developing human brain function are limited. Research involving live embryonic subjects is constrained

Dr Max Ortiz Catalan of Chalmers University of Technology, Sweden, has developed a new theory for the origin of the mysterious condition, ‘phantom limb pain’. Published in the journal Frontiers in Neurology, his hypothesis builds upon his previous work on a revolutionary treatment for the condition, that uses machine learning and augmented reality. Phantom limb
