Mosquitoes transmit a wide variety of nasty microbes, from viruses like dengue, yellow fever and Zika, to parasites like malaria. The sheer number and diversity of diseases transmitted by mosquitoes makes vaccine development a challenge. But what if a vaccine could, instead, target the mosquito?
The stories told by patients with Alzheimer's Disease show us how entwined memory is with our sociability.
Ebola is the most famous of the hemorrhagic fever viruses, but it’s not the only one. Another killer has caused outbreaks throughout the Middle East and Asia, infecting more than 1,000 people every year since 2002.
A new paper provides solid evidence that the cause of the apparent uptick in celiac disease cases is not due to wheat breeding. So, the search for the real cause continues.

A large study focusing on breast cancer treatment demonstrates that for estrogen responsive, HER2-negative cancers, the majority of women do not require chemotherapy.
Reductionism is the basis for most science. Since so many factors can be involved, isolating them in a lab-bench experiment can yield valuable insights. For epidemiological studies, it doesn’t work as well.
Nearly a century ago, Lord Carnavon, who attended the opening of King Tut’s Tomb, died shortly afterwards, in April 1923. At the time, the sensational media linked his death to supernatural causes activated by the curse of the mummy’s tomb. More recently, this tale was rationalized by suggesting that his death was due to ancient disease causing microbes, lurking in the tomb, rather than supernatural influences. Modern technology has been used to examine mummies to attempt to diagnose any infections that they had, which might have been the cause of death. Mummies and other reasonably well-preserved corpses have indeed yielded signs of infection. In some cases, DNA from ancient corpses has been sequenced and revealed the identity of the infectious agents responsible.
Throughout its history, ebola has caused humanity to hunker down and hope for the best. But in the Democratic Republic of Congo, the battle has turned. Instead of containment, quarantine and waiting it out, science is attacking.
Healthcare has cultural roots. Chicken soup as “Jewish penicillin” exemplifies one culture’s role in signifying quality, remedy and affective connotations like comfort.
