Cure for dry eye could be a blink away

Cure for dry eye could be a blink away

A treatment for dry eye — a burning, gritty condition that can impair vision and damage the cornea — could some day result from computer simulations that map the way tears move across the surface of the eye. Kara Maki, assistant professor in Rochester Institute of Technology’s School of Mathematical Sciences, contributed to a recent National Science Foundation study seeking to understand the basic motion of tear film traversing the eye Continue reading

Sperm cells are extremely efficient at swimming against a current: How sperm travel long distances, through difficult terrain, to reach an egg

Sperm cells are extremely efficient at swimming against a current: How sperm travel long distances, through difficult terrain, to reach an egg

Like salmon traveling upstream to spawn, sperm cells are extremely efficient at swimming against the current, according to research to be published this week. The discovery, to be published in the journal eLife by researchers at MIT and Cambridge University, may help us to understand how some sperm travel such long distances, through difficult terrain, to reach and fertilize an egg. Of the hundreds of millions of sperm cells that begin the journey up the oviducts, only a few hardy travelers will ever reach their destination. Continue reading

‘Virtual human’ shows that stiff arteries can explain cause of high blood pressure

High blood pressure is highly age-related and affects more than 1 billion people worldwide. But doctors can’t fully explain the cause of 90 per cent of all cases. Continue reading

Novel home cleaning method to reduce asthma

Novel home cleaning method to reduce asthma

A team of researchers from the University of South Carolina received two patents for a new method to rid carpets, mattresses and other furniture of harmful allergens and pests that cause asthma. The patents (Methods and Compositions for Eliminating Allergens and Allergen-Producing Organisms) are the work of Michael Matthews, Jian Zhang and Allan Quick and uses carbon dioxide (CO 2 ) to “freeze clean” home fabrics.

Breakthrough method for making Janus or patchy capsules

Breakthrough method for making Janus or patchy capsules

Hollow capsules that have a selectively permeable shell are promising candidates as tiny containers for molecules, particles or bubbles, and are becoming increasingly important in a wide variety of applications. But making these kinds of capsules with more than one kind of substance on their shells has been challenging — until now Continue reading

Going beyond the surface: New tech could take light-based cancer treatment deep inside the body

Going beyond the surface: New tech could take light-based cancer treatment deep inside the body

Photodynamic therapy (PDT) is an effective treatment for easily accessible tumors such as oral and skin cancer. But the procedure, which uses lasers to activate special drugs called photosensitizing agents, isn’t adept at fighting cancer deep inside the body. Thankfully, that’s changing due to new technology that could bring PDT into areas of the body which were previously inaccessible. Continue reading
