Looking for the genes that affect a person's level of response to alcohol

...hich changes their reaction per drink, their liver gets a little slower in metabolizing alcohol, their brain gets a little more sensitive to alcohol, and when they get sick, they take medications, all of which affe...

Changes to embryos can elicit change in adult fish

...-levers. "We found that as the closing in-lever gets longer, the out-lever gets shorter and vice-versa," explained Streelman. "When the in-lever is long, this gives the jaw a hig...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

...minal (striatum)," Svendsen says. "The bonus is it gets transported back to the substantia niagra." The transplanted cells, according to Behrstock, survived and continued to produce GDNF in laboratory animals for up to three months. One hurdle that needs to be overcome before such a technique could be a...

Chlamydia parasite lives off our fat

...with three million new cases a year. Chlamydia gets around because it knows its hosts so well. It's an "obligate intracellular parasite" which means that it relies on its eukaryotic host for everything from reproduction to synthesizing ATP, all while living inside a membrane-bounded vacuole that provi...

How the neuron sprouts its branches

...early that this cargo that originates in the Golgi gets directed towards the one longest dendrite in a highly preferential way," he said. "As cargo comes out of the Golgi, it does not go randomly to the cell surface." Ehlers and his colleagues also found that the Golgi outposts appeared to locate themselv...

Liquid ventilation

...the lungs folding in on themselves before the baby gets stronger. The respirators usually employd in these cases provide artificial surfactant, but not always in sufficient amounts to provide correct therapy. In order to alleviate this situation, the Nautical School at the University of the Basque Coun...

Picking apart how neurons learn

...onses like the vestibulo-ocular reflex. This study gets at the heart of how LTD occurs, specifically how PICK1 controls the Purkinje cell's response to the signaling molecule, glutamate," says Richard L. Huganir, Ph.D., a Howard Hughes Medical Institute investigator and chair of the Solomon H. Snyder Depa...

Tiny polyps gorge themselves to survive coral bleaching

... means that coral like Montipora can switch how it gets its food so that it can sustain itself in a bleached state much longer than can corals like Porites," she said. "While bleached Porites is limited by how much energy reserves it has, bleached Montipora is not. That's good news for Montipora and cor...

Marine mammals are on the frontline of failing ocean health

... didn't think about things like how much cat feces gets in to the environment - how what we dump on our lawns and sidewalks flows into streams to rivers and into the ocean," says Conrad. But with the discovery that otters in areas with heavy freshwater outflow are nearly three times as likely to be infe...

Ernst Mayr's theory illustrated in genetic epidemiology studies

...se occur when a very small population of a species gets established in a new area. Because the population is very small, there is a lot of genetic randomness, and there is only a subset of the genetic variation of the ancestral population, and the frequencies of different kinds of genes can be changed dr...

UW-Madison engineers squeeze secrets from proteins

...opular ad for detergent once claimed that "protein gets out protein." The idea behind this is that engineered enzymes are at work in the wash breaking down elements of a stain. "Once a protein is folded, you can actually unfold it or destabilize it, either by heating it up, or by adding solvents to the s...

Aggression-related gene weakens brain's impulse control circuits

...serotonin. These, in turn, influence how the brain gets wired during development. The variations may have more impact on males because they have only one copy of this X-chromosomal gene, while females have two copies, one of which will be of the H variant in most cases. Several previous studies had link...

Honeybee decision-making ability rivals any department committee

... collective decisions," said Seeley. When a hive gets too crowded, its queen and half the hive will swarm to a nearby tree and quietly wait while several hundred scouts go house hunting. To explore the decision-making process, the researchers conducted a series of experiments. To study the waggle danc...

Multi-million pound UK Biobank underway

...he planned procedures go smoothly before the study gets underway nationwide later in the year, when around eight to 10 assessment centres will be running at any one time around the UK. Sir Alan Langlands, the Chair of UK Biobank's Board and previously Chief Executive of the NHS, said: "The NHS treats the...

Insects that produce males from unfertilized eggs reveal a surprising cellular feat

First demonstration of 'teaching' in non-human animals

Sex: It's costly but worth it. Just ask a microbe

...uce and transmit the signal, and the other partner gets distracted by the mating signal and loses interest in reproducing on its own." The irony is that despite the high cost of sex there are benefits. "In many microbes, mating and sexual reproduction produce genetically diverse and hardy progeny bette...

Alzheimer's found to be mostly genetic

...elevant not only for whether but also for when one gets the disease. Also, you can't go from these results to any one individual." Even identical twins, who share all their genes, differ in their vulnerability. The study found only a 45 percent concordance rate for identical male pairs. This means that o...
