Researchers working with monkeys get closer to effective HIV vaccine

Research conducted in rhesus macaques could help scientists as they work to develop an effective HIV vaccine for people. Researchers revaccinated six rhesus macaques that had developed low levels of protective antibodies after being vaccinated in a previous study as well as six monkeys that had developed high antibody levels, then exposed all the monkeys to simian HIV. The high-titer monkeys did not develop SHIV, and researchers say the study will help determine the level of antibodies that an HIV vaccine must induce to protect humans.

Scientists develop swine fever-resistant pigs with CRISPR-Cas9

Scientists from Jilin University in China have developed pigs with inheritable classical swine fever virus resistance using CRISPR-Cas9 gene-editing tool and RNA interference.

A vaccine that scientists say could help fight the opioid crisis has shown promise in mice, according to Virginia Commonwealth University researchers. A tetanus vaccine was attached to opioid molecules to spark an immune response to the drugs, and the resulting antibodies blocked drug molecules from crossing the blood-brain barrier.

Cancer drug shows promise in multiple species, headed for canine trial

A new compound tested in mice and pigs shrank sarcoma tumors and seemed to reduce the ability of cancer to spread, and researchers hope the work will ultimately help humans whose cancers typically carry a poor prognosis. The similar findings in separate species are encouraging, and scientists plan to continue their work in a clinical trial involving dogs, which develop sarcomas spontaneously the way humans do.

Mouse study supports idea of Alzheimer's disease transmissibility

A study involving mice supports the hypothesis that certain medical or surgical procedures could transmit proteins associated with Alzheimer's disease from person to person, and researchers are continuing studies in mice to further explore the idea. Amyloid proteins associated with the disease resist standard methods used to decontaminate surgical instruments. "The risk may turn out to be minor -- but it needs to be investigated urgently," says neurologist John Collinge, who led the study.

Scientists harness wasp venom to kill dangerous bacterial infection

Scientists have isolated a peptide from the venom of Polybia paulista wasps that is 12 amino acids long and kills bacteria by interfering with their cell membranes. The scientists reported in Communications Biology that altering the peptide's structure yielded a compound capable of eliminating Pseudomonas aeruginosa infections in mice, and senior author Cesar de la Fuente-Nunez says the approach can be used on other antimicrobial peptides.

Scientists find evidence of reverse zoonosis in Antarctic birds

Scientists say Antarctica's seabirds are not safe from introduced pathogens, including some that likely came from humans, after finding evidence of pathogens including salmonella and antibiotic-resistant campylobacter in penguins, southern giant petrels, brown skuas and kelp gulls. "This means that sooner or later human activity will introduce pathogens to Antarctic fauna that could cause mass deaths and even local extinctions," said researcher Jacob Gonzalez-Solis.

Booker proposes bill that would cripple NHP research

Sen. Cory Booker, D-N.J., has introduced legislation that "would seek to prevent unnecessary and unethical animal testing practices on primates." The legislation would restrict primate research and require approval by a new committee of experts. It would also require the National Academy of Sciences to review "preexisting fields of research and determine whether nonhuman primate research has led to meaningful clinical interventions." The legislation would restrict funding awards and prohibit research for consumer goods and products. Read more from Booker's website.
