How the study of hibernating bears could help humans heal

Deseret News August 06, 2025
In a Deseret News article about University of Utah research that suggests the genetic tool kit that enables animals like bears to survive hibernation could also exist in humans, Domenico Tupone, Ph.D., discusses an OHSU study that identified a brain-based mechanism called thermoregulatory inversion, a process that allows animals to lower their core body temperature without triggering the usual warming responses like shivering or burning a specific type of fat in the body; he says: “The idea is to reduce the body temperature to a lower level so that tissues like the brain or heart don’t need as much oxygen. That could improve outcomes from strokes or heart attacks. If we had a mechanism that allows us to transform humans into hibernating animals, we could achieve and control therapeutic hypothermia much better.”

The quest to create gene-edited babies gets a reboot

NPR August 06, 2025
NPR interviews Paula Amato, M.D., and others about “genetically engineered humans” after eight healthy babies were born in the U.K. using genetic material from three people; she says, “NIH doesn't typically support human embryo research, so if the technology bros are interested, that would be welcome in the field.”

OHSU gets $3.5M to study aggressive oral cancer

Dr Bicuspid August 06, 2025
Continued coverage of a $3.5 million NIH grant awarded to Luiz Bertassoni, D.D.S., Ph.D., to study how oral cancer interacts with bone using a new tumor-bone interface on a chip.”

Understanding Immunologic Complications of Measles

The Rheumatologist August 06, 2025
In a The Rheumatologist article about patients asking whether they need to be revaccinated or tested for measles immunity, Kevin Winthrop, M.D., says: “The true numbers of cases are probably much higher than the officially confirmed cases would indicate because many patients may not come to medical attention.”

Tetanus Shots: Lifesavers or Overkill?

Medscape August 05, 2025
Medscape notes the review by Slifka and colleagues emphasizes that adult booster doses, which have already been phased out in several European countries, can be safely discontinued if high vaccination coverage in children is maintained and vaccines remain available for specific clinical needs.

Study: Ending adult boosters for tetanus, diphtheria could save US billions

Healio August 05, 2025
A new review by Mark Slifka, Ph.D., and colleagues finds the U.S. could safely drop tetanus and diphtheria booster shots for adults and save an estimated $1 billion a year; he says: “We ask that [the U.S.] consider revisiting the current guidelines for adult booster vaccinations."

How does the morning-after pill work?

LiveScience August 05, 2025
In an interview with Yahoo!News about how the morning-after pill works, Alison Edelman, M.D., says: "Although the morning-after pill is kind of a catchy name for emergency contraception, it’s actually misleading since emergency contraception works best if you take it as soon as possible after unprotected sex."

Do You Need Tetanus Boosters Every 10 Years?

Slifka says: "This study is actually a pro-vaccine study. If we maintain our high vaccination coverage for tetanus, diphtheria, and pertussis for kids, we no longer need the vaccine for adults."
