The new COVID-19 vaccines: Will they be safe?
Just within the past week, pharmaceutical companies have announced encouraging news about two COVID-19 vaccines in the final development phase. As more vaccine developers announce similar reports in the coming weeks and months, it’s key to remember that vaccine safety is as important as effectiveness against the virus. Fortunately, scientists have learned lessons from the ... Read More about The new COVID-19 vaccines: Will they be safe?
A COVID-19 DNA nanoswitch: A new kind of test for a new kind of virus
When the COVID-19 pandemic shut down research laboratories across the country, several labs at Boston Children’s Hospital geared up, including that of Wesley Wong, PhD. He and his team responded to the threat by developing a new, easy diagnostic test for COVID-19. Wesley Wong “Our technology, a DNA nanoswitch, is a new way of probing ...

Platelet profiles could enhance care for bleeding disorders, cardiovascular disease, cancer
The trillion-odd platelets in our blood are best known for controlling bleeding, helping clots form when we sustain an injury. But platelets can also go rogue. They contribute to clotting in cardiovascular disease and diabetes, leading to strokes and heart attacks, and can be hijacked by cancers to help them spread. Key takeaways A new ...

Getting to a COVID-19 vaccine as fast and as safely as possible
The novel coronavirus is not expected to disappear anytime soon. With physical distancing, virus testing, contact tracing, and potentially new therapeutics, we may be able to keep it partially at bay. But many eyes are looking toward a COVID-19 vaccine, and scientists are feeling the urgency. Key takeaways. Work is moving quickly, but to show ...

Hydroxychloroquine and COVID-19: What we know so far
Despite the current hype, infectious disease experts and others are cautious about using chloroquine drugs in the current COVID-19 pandemic. While the urgent need for COVID-19 treatments justifies the rapid pace of trials, several concerns have been raised related to the limitations of studies published so far. Kristin Moffitt, MD The drugs chloroquine and hydroxychloroquine ... Read More about Hydroxychloroquine and COVID-19: What we know so far
Could plasma from recovered COVID-19 patients help others?
As new cases of COVID-19 mount daily, treatment revolves around supportive therapy to reduce symptoms, meaning there are no treatments shown to slow down or kill the SARS-CoV-2 virus. One new idea actually isn’t so new: transfusing blood plasma from recovered COVID-19 patients into patients currently sick with the disease. Last week, the Food and Drug ...

100 years after the advent of TB vaccines, formulations vary widely
Each year, more than 100 million newborns around the world receive vaccinations against Mycobacterium tuberculosis, or TB, which infects about one-quarter of the world’s population. Facilities across the world produce several different formulations of these vaccines, known as Bacille Calmette-Guérin (BCG) vaccines. These are given interchangeably, yet new research from the Precision Vaccines Program at ... Read More about 100 years after the advent of TB vaccines, formulations vary widely
Shooting for the moon: From diagnosis to custom drug, in one year
Ed. note: Mila passed away in February 2021, at age 10. The Mila’s Miracle Foundation continues to work to pave a pathway for personalized treatments. The FDA recently released a draft guidance on testing custom antisense oligonucleotides (ASOs) in patients. One weekend in January 2017, Timothy Yu, MD, PhD, was relaxing at home when his ...

Opioid alternative? Taming tetrodotoxin for precise painkilling
Opioids remain a mainstay of treatment for chronic and surgical pain, despite their side effects and risk for addiction and overdose. While conventional local anesthetics block pain very effectively, they wear off quickly and can affect the heart and brain. Now, a study in rats offers up a possible alternative, involving an otherwise lethal pufferfish ... Read More about Opioid alternative? Taming tetrodotoxin for precise painkilling
Science Seen: New microscope reveals biological life as you’ve never seen it before
Astronomers developed a “guide star” adaptive optics technique to obtain the most crystal-clear and precise telescopic images of distant galaxies, stars and planets. Now a team of scientists, led by Nobel laureate Eric Betzig, PhD, are borrowing the very same trick. They’ve combined it with lattice light-sheet to create a new microscope that’s able to capture real-time, incredibly ...
