The world's largest study into the long-term health impact of floods has found that there are surges in hospitalizations for months after an event – and current responses are inadequate when it comes to treating cancer, diabetes, mental health and more.
-
Looking beyond jabs, sprays or tablets, scientists are thinking outside the box for delivering antiviral medication to prevent the spread of highly transmissible bugs. Their secret weapon? Chewing gum – but one made from a rather fascinating bean.
-
A three-year study has found robust evidence that one vaccine for respiratory syncytial virus offers older adults long-term protection, even if efficacy wanes. Despite this, just one dose cut serious illness by nearly two thirds across three seasons.
-
A decade-long study of 35 million Americans in 10 states has found that group A streptococcus infections have more than doubled. What's more, "strep" – which can cause a bizarre flesh-eating disease – has become increasingly resistant to antibiotics.
-
It's never a good thing, when a bacterial biofilm forms on the surface of a medical implant. There could soon be a new way of eradicating such films, however, using tiny remote-control liquid-bodied robots.
-
Scientists have made a major breakthrough in the accuracy and speed at which serious and often deadly pathogen infections can be diagnosed and treated. Often, this is time that is critically important in saving a patient's life.
-
A new zombie pathogen has been discovered in Ireland. This insidious fungus infects cave spiders and alters their behavior to help spread its spores to new victims.
-
HIV has become a more manageable condition in recent years, but a full cure remains elusive. Now, scientists have found promise in permanently eliminating the virus, thanks to a drug already approved by the FDA to fight cancer.
-
A coughing, sneezing, 3D-printed model of the human nose and upper airway has provided researchers with a better understanding of how airborne infections are transmitted. The knowledge will aid in developing effective ways of reducing that spread.
-
The US has recorded its first death due to avian influenza. The man had been infected by a H5N1 variant with a genetic mutation, helping it target upper respiratory tract receptors – one also seen in the Canadian teen who fell critically ill last year.
-
If you were given a choice of vaccine delivery method, would you rather a needle or a skin cream? Thought so. Well, the latter might be a viable option soon, as Stanford scientists have used a topical cream to strongly vaccinate mice against tetanus.
-
Surgical stitches are good for helping wounds heal, but they can pop open with too much movement. Scientists have now turned that weakness into a strength, developing stitches that generate an electric charge when stretched and heal wounds faster.
