A new probe may aid in complete removal of cancer tissue during surgery
An optical fiber probe can distinguish cancer tissue and normal tissue at the margins of a tumor being excised, in real time, by detecting the difference in pH between the two types of tissue. This has the potential to help surgeons avoid removing too much healthy tissue during surgery and also avoid performing additional surgeries later to remove any cancer tissue left behind.

A method for storing vaccines at room temperature
Shipping vaccines in an unbroken temperature-controlled supply chain (a "cold chain") all the way to recipients is a major logistical and financial challenge in remote areas and developing countries. According to Doctors Without Borders, the need to keep vaccines within a temperature range of 2-8°C is one of the main factors behind low immunization-coverage rates.

Lack of sleep costing US economy up to 411 billion dollar per year
A lack of sleep among the U.S. working population is costing the economy up to 411 billion dollar a year, which is 2.28 percent of the country's GDP, a new report finds. According to researchers at the not-for-profit research organisation RAND Europe sleep deprivation leads to a higher mortality risk and lower productivity levels among the workforce.

Genetic link to fatal health condition could aid future treatment
"Early detection is key to this condition which, if left untreated, can become a ticking time bomb for patients", says Professor Matt Bown, University of Leicester. Thousands of lives could be saved every year after it was discovered a fatal cardiovascular condition could be linked to four genes, research has found.

New ways to measure solid stress in tumors could lead to improved understanding, therapies
Massachusetts General Hospital (MGH) investigators have developed new methods for mapping and measuring solid stress - the force exerted by solid and elastic components - within tumors, an accomplishment that may lead to improved understanding of those forces and their consequences and to novel treatment strategies.

Sometimes just watching hurts - and the signs of pain are seen in the brain
Some people claim to experience pain just watching something painful to happen. This is true especially of people suffering from complex regional pain syndrome (CRPS), a disabling chronic pain disorder in a limb. In CPRS patients, both own movements and just observing other persons' movements may aggravate the pain.

Vestibular function declines starting at age 40
A new study led by researchers at Massachusetts Eye and Ear found that vestibular thresholds begin to double every 10 years above the age of 40, representing a decline in our ability to receive sensory information about motion, balance and spatial orientation. The report was published in "Frontiers in Neurology".

First steps to neutralizing Zika
As Zika spreads throughout the world, the call for rapid development of therapeutics to treat Zika rings loud and clear. Taking a step further in identifying a possible therapeutic candidate, a team of researchers have discovered the mechanism by which C10, a human antibody previously identified to react with the Dengue virus, prevents Zika infection at a cellular level.
