    A new tool could one day improve Lyme disease diagnosis

    A new testing method can distinguish between early Lyme disease and a similar tick-borne illness, researchers report. The approach may one day lead to a reliable diagnostic test for Lyme, an illness that can be challenging to identify.

    Using patient blood serum samples, the test accurately discerned early Lyme disease from the similar southern tick‒associated rash illness, or STARI, up...

    Gene editing creates virus-free piglets

    Pigs are a step closer to becoming organ donors for people.

    Researchers used molecular scissors known as CRISPR/Cas9 to snip embedded viruses out of pig DNA. Removing the viruses — called porcine endogenous retroviruses, or PERVs — creates piglets that can’t pass the viruses on to transplant recipients, geneticist Luhan Yang and colleagues report online August 10 in Science.

    Spread of misfolded proteins could trigger type 2 diabetes

    Type 2 diabetes and prion disease seem like an odd couple, but they have something in common: clumps of misfolded, damaging proteins.

    Now new research finds that a dose of corrupted pancreas proteins induces normal ones to misfold and clump. This raises the possibility that, like prion disease, type 2 diabetes could be triggered by these deformed proteins spreading between cells or even...

    One in three U.S. adults takes opioids, and many misuse them

    Nearly 5 percent of U.S. adults misused prescription opioids in 2015, a new study shows.

    Based on the National Survey on Drug Use and Health, an in-person survey of more than 50,000 people, researchers estimated that 91.8 million, or 37.8 percent, of adults used prescription opioids in 2015. Some 11.5 million people misused the painkillers and 1.9 million people reported opioid...

    Slug slime inspires a new type of surgical glue

    View video

    For a glue that holds up inside the body, turn to the humble slug, Arion subfuscus. A new super-sticky material mimics slug slime’s ability to stick on slick wet surfaces and could lead to more effective medical adhesives.

    The material has two parts: a sticky layer that attaches to a surface, and a shock-absorbing layer that reduces strain. That makes the adhesive less...

    Cows produce powerful HIV antibodies

    An unlikely hero has emerged in the quest to fight HIV: the cow. In a first for any animal, including humans, four cows injected with a type of HIV protein rapidly produced powerful antibodies against the virus, researchers report. Learning how to induce similar antibodies in humans may be key to a successful HIV vaccine.

    The antibodies, called broadly neutralizing antibodies, can stop...

    The fight against gonorrhea gets a potential new weapon: a vaccine

    A vaccine against meningitis has an unexpected side effect: It appears to target gonorrhea, too. If confirmed, the results represent the first instance of a vaccine reducing gonorrhea infections.

    After receiving a vaccine aimed at a type of meningitis, people were less likely to contract gonorrhea, scientists report online June 10 in the Lancet. That’s a big deal because worldwide each...

    Getting a flu ‘shot’ could soon be as easy as sticking on a Band-Aid

    DIY vaccination may be on its way. In the first test in adults, a Band-Aid‒like patch studded with dissolving microneedles safely and effectively delivered a dose of influenza vaccine.

    People using the patch had a similar immune response to the flu vaccine as those who received a typical flu shot, researchers report online June 27 in the Lancet. And nearly all of the patch users...

    Bones make hormones that communicate with the brain and other organs

    Long typecast as the strong silent type, bones are speaking up.

    In addition to providing structural support, the skeleton is a versatile conversationalist. Bones make hormones that chat with other organs and tissues, including the brain, kidneys and pancreas, experiments in mice have shown.

    “The bone, which was considered a dead organ, has really become a gland almost,” says Beate...

    Protein in Parkinson’s provokes the immune system

    Bits of a protein that builds up in Parkinson’s disease trigger the immune system, causing it to tag them as foreign invaders.

    In a blood test, immune cells called T cells became activated when exposed to the protein in about 40 percent of Parkinson’s patients in a new study. This autoimmune response may contribute to the progression of the disease, the researchers report online June 21...
