Influenza kills up to 650,000 people and hospitalizes many more each year, yet activists are trying to put an end to promising research on a universal flu vaccine. Research in mice, dogs, rats and chickens has led to influenza treatments and vaccines, but those vaccines don't always match the circulating strain, and research on rabbits, ferrets and llamas, among other animals, could yield a universal vaccine unless misguided activists succeed.

Animal studies are clinically relevant to human health, but reporters as well as researchers often exaggerate study findings, contributing to skepticism, writes biochemist and former research scientist Yella Hewings-Martin. Neurobehaviorist Vootele Voikar says scientists should take species-specific differences into account as much as possible and present their findings without hype, and news outlets should also avoid hype and ask and present different views to promote objective discussion.
A battery-free pacemaker received plenty of power to function correctly from the heartbeat of a pig into which it was implanted, and it corrected arrhythmia when implanted in another pig. The device is also being tested in dogs and must be optimized before it can be used in people, but the study results suggest the concept could help reduce the need for repeated surgeries to replace pacemaker batteries.
Researchers at the University of California, Davis, received a $9 million grant from the NIH to study the safety of CRISPR gene editing and ensure that only targeted, disease-specific genes are altered with no unintended effects. UC Davis was chosen based on faculty expertise in nonhuman primate research, and a new research center, called the Nonhuman Primate Testing Center for Evaluation of Somatic Cell Genome Editing Tools, will be established.
Genetically engineered fruit flies were used to screen a customized combination of cancer drugs before it was given to a terminally ill patient with colon cancer, according to a study published in Science Advances. The screened drugs helped shrink the patient's tumors significantly, and researchers say the method may lead to more effective treatments.
Electrical stimulation of an area at the back of the nose might help improve blood flow and improve neurologic outcomes in patients with acute ischemic stroke, according to a study published in The Lancet. Data showed the therapy, which was tested in animals before being tried in people, works up to 24 hours after a stroke begins, which could help patients who miss the treatment window for thrombolysis, researcher Dr. Jeffrey Saver says.
Veterinarian Brea Sandness and her team at Michigan State University Veterinary Medical Center used grafts made of descaled cod fish skin to heal second- and third-degree burn wounds on a dog that survived a house fire. Minimal sedation was needed to place the skins, which were absorbed by the dog's body, and the technique could become "a highly effective treatment tool," Dr. Sandness says.
Sylvatic plague killed 70% of the black-tailed prairie dogs in the winter of 2017-18 at Montana's UL Bend National Wildlife Refuge, leading to decimation of the refuge's endangered black-footed ferret population, which depends on prairie dogs for food. An oral vaccine distributed in the refuge failed to prevent the die-off, but efficacy has not been ruled out at some other prairie dog colonies.
Animal rights groups mislead the public about animal research, but FBR is fighting back with facts. In this resource, highly respected neuro-oncologist and FBR Board Vice-Chair Dr. Henry S. Friedman refutes myths surrounding animal research with scientific evidence and sets the record straight on the reality and benefits of animal research. Check it out.
For 35 years, FBR has advanced biomedical research for the sake of both human and animal health. We can't do our job without your support. Please give what you can. Together we will continue to make a difference.
Don't dwell on what happened, no matter how bad it was. Find something else to do. Find something to do to help others.
