A new-born honey bee worker (Apis mellifera) breaks free from her nursery chamber in the colony nest. A few weeks later, she will leave the hive in search for nectar and pollen to feed her siblings and mother queen. The genes vitellogenin and ultraspiracle, which regulate the bees’ behavioral transition to foraging tasks, also coordinate their carbohydrate metabolism, blood sugar levels, sweet taste, and several metabolic genes in adipose tissue. When vitellogenin and ultraspiracle are simultaneously suppressed in adipose cells, the bees develop a metabolic syndrome similar to Type 1 diabetes. Continue reading →
While it sounds too remarkable to believe, recent scientific studies have shown that ketamine — an anesthetic drug used in human and veterinarian medicine — does indeed effectively treat severe depression. And it takes effect within two hours.
“My veterinarian made me do it! I love my veterinarian so much, that I do exactly what he/she tells me to do. We all listen to the alternative practitioners warning about the potential side effects and how vaccination is not a simple thing but is a true medical procedure with risks and benefits just like all medical procedures. But I’m scared because I’ve heard that it can have dangerous, life threatening consequences, not just for my pets but for my kids and me, too. I’m just so afraid not to get those booster shots, that I get the reminders for in the mail, all the time. It seems all we ever get are scare tactics thrown at us if we raise any objections to these vaccines. We’re just told about how risky and unconscionable it is to NOT vaccinate. The ultimate blow being when my vet tells me, I won’t be able to bring my pet back to the clinic unless I vaccinate and boost regularly. What if I have an emergency, then what?”
Sound familiar? What are we supposed to do in the face of such tactics? For those of us who dare to recommend caution about vaccination, especially annual boosters and/or even the appropriate time Continue reading →
Scientists at Stanford report that they can turn human skin cells directly into functioning nerve cells in the lab dish. The process does not involve an intermediate step of forming a stem cell, but directly converts skin cells into neurons.
Last year this group showed that they could accomplish this direct conversion with mouse cells. The new results, reported in the journal Nature, accomplish this conversion for the first time with human cells by adding four genes to the skin cells. Other researchers have obtained similar direct conversion results in the formation of blood, heart, and insulin-secreting cells.
