A NASA-led study suggests the stress of spaceflight seems to trigger various types of herpes to reactivate in astronauts.
- The study examined saliva, blood and urine obtained from astronauts who went on short- and long-term space missions.
- The results showed that virus reactivation rates in these astronauts were much higher than controls.
- Spaceflight seems to weaken the immune system, enabling these once-dormant viruses to reactivate and potentially cause serious health problems.
A bill in New York would let older kids get vaccinations against their parents' wishes.
- Teens 14 and older should be able to get vaccinated on their own, says a new bill in New York.
- Lawmakers were inspired by Ethan Lindenberger, an Ohio teen who fought to take vaccines against his mom's wishes.
- Anti-vaccination attitudes have been blamed for recent measles outbreaks.
- CDC estimates say that 154 million antibiotic prescriptions are given out each year, 30 percent of which are unnecessary.
- The overuse of antibiotics have led to the rise of nigh-untreatable superbugs.
- Phage therapy offers a promising new way to overcome antibiotic resistance, but it also comes with its own risks and challenges.
Scientists say the virus monitors bacterial chemical exchanges
- When bacteria broadcast their presence, bacteriophages may be listening
- A stunning discovery of cross-domain communication
- Research could lead to new, custom- targeted medicines
Delivered together, the two join forces to eradicate drug-resistant bacteria.

In the fight against drug-resistant bacteria, MIT researchers have enlisted the help of beneficial bacteria known as probiotics.
In a new study, the researchers showed that by delivering a combination of antibiotic drugs and probiotics, they could eradicate two strains of drug-resistant bacteria that often infect wounds. To achieve this, they encapsulated the probiotic bacteria in a protective shell of alginate, a biocompatible material that prevents the probiotics from being killed by the antibiotic.
