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
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 ... Read More
Gene therapy halts progression of cerebral adrenoleukodystrophy in clinical trial
Adrenoleukodystrophy — depicted in the 1992 movie “Lorenzo’s Oil” — is a genetic disease that most severely affects boys. Caused by a defective gene on the X chromosome, it triggers a build-up of fatty acids that damage the protective myelin sheaths of the brain’s neurons, leading to cognitive and motor impairment. The most devastating form of the ... Read More
Landmark moment for science as the FDA approves a gene therapy for the first time
Today, the Food and Drug Administration approved a gene therapy known as CAR T-cell therapy that genetically modifies a patient’s own cells to help them combat pediatric acute lymphoblastic leukemia (ALL), the most common childhood cancer. It is the first gene therapy to be approved by the FDA. “This represents the progression of the field of gene ... Read More
Effective vaccination of newborns: Getting closer to the dream
In many parts of the world, babies have just one chance to be vaccinated: when they’re born. Unfortunately, newborns’ young immune systems don’t respond well to most vaccines. That’s why, in the U.S., most immunizations start at two months of age. Currently, only BCG, polio vaccine and hepatitis B vaccines work in newborns, and the ... Read More
DIY pain relief with light-activated local nerve blocks
You’ve just had a root canal or knee surgery — both situations that will likely require some sort of local pain medication. But instead of taking a systemic narcotic with all its side effects, what if you could medicate only the part of your body that hurts, only when needed and only as much as ... Read More
Gene therapy gets in the ring with another disease
Seeing that his mother, Kadriye, wasn’t looking, Emir Seyrek got an impish grin on his face, the kind only a two-year-old can have. He quietly dumped his bowl of dry cereal out on his bed and, with another quick look towards his mother, proceeded to pulverize the flakes to dust with his toy truck. The ... Read More
A new start for gene therapy for “bubble boy” disease: First U.S.-treated patient doing well
Until this month, Agustín Cáceres’s baptism was the only time his family could come close to him. Everyone had to wear masks, gloves and gowns. After that, he went into isolation, along with his mother Marcela, who came out only for meals. His father Alberto, and his four-year-old brother Jeremías, kept to a separate bedroom. ... Read More
