heroin medfører epigenetisk gen-ekspressionspåvirkning (histon-acetylering)
Epigenetic alteration a promising new drug target for heroin use disorderThe past few years have seen an explosion of heroin abuse and deaths from opiate overdose. But little is known about the molecular underpinnings of heroin addiction. A new study has found that heroin use is associated with excessive histone acetylation, an epigenetic process that regulates gene expression. More years of drug use correlated with higher levels of hyperacetylation. The study provides

Laser pulses in air detect uranium from afar A technique for detecting enriched uranium with lasers could help regulators sniff out illicit nuclear activity from as far as a couple of miles away. The technique, often used to identify chemicals at a distance, can also distinguish between ordinary uranium-238 and the fission-prone uranium-235. Just three fewer neutrons make a big difference in the element's potential for destruction. "It's a

Liquids in thin battery could cool stacks of computer chips A newly designed "flow" battery could make it possible to stack computer chips like pancakes to save space and energy. The battery, only around 1.5 millimeters thick, uses two liquid electrolytes to power and cool the chips at the same time. "The chips are effectively operated with a liquid fuel and produce their own electricity," says Dimos Poulikakos, a professor of thermodynamics at ETH Zurich

When the sea ice melts, juvenile polar cod may go hungryPolar cod fulfil a key role in the Arctic food web, as they are a major source of food for seals, whales and seabirds alike. But the polar cod themselves might soon be the hungry ones. Under the ice of the central Arctic, the juvenile fish are indirectly but heavily dependent on ice algae. As a result, retreating sea ice could have far-reaching impacts on the food web. Though researchers have long

The pouches exploit patent pending high consistency enzymatic fibrillation of cellulose (HefCel) technology.
Ice age thermostat prevented extreme climate coolingDuring the ice ages, an unidentified regulatory mechanism prevented atmospheric carbon dioxide concentrations from falling below a level that could have led to runaway cooling, reports a team of researchers. The study suggests the mechanism may have involved the biosphere, as plants and plankton struggled to grow under very low carbon dioxide levels.

Zebrafish without stripesDowling-Degos disease is a hereditary pigmentation disorder that generally progresses harmlessly. However, some of those affected also develop severe skin inflammation. An international team of researchers has now found a cause for this link. Their knowledge comes thanks to an animal that is known among aquarium owners for its characteristic pigmentation: the zebrafish.
Probiotics may not always be a silver bullet for better healthResearchers have investigated the impact of probiotics on gut health and cognitive function. In rats fed on 'junk' diets, the probiotic medicine was able to significantly impact microbial composition in the gut and prevent memory loss. But for rats on a healthy diet, the probiotic did little to influence microbial composition and actually impaired memory function.

What makes farmers try new practices?Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others. A group of researchers wanted to know which farmers are most likely to adopt multifunctional perennial cropping systems — trees, shrubs, or grasses that simultaneously benefit the environment and generate high-value products that can be harvested for a profit.
Flies and bees act like plant cultivatorsPollinator insects accelerate plant evolution, but a plant changes in different ways depending on the pollinator. After only nine generations, the same plant is larger and more fragrant if pollinated by bumblebees rather than flies, as a study reveals.

Bariatric surgery impacts joint replacement outcomes in very obese patientsIn morbidly obese patients, bariatric surgery performed prior to a total hip or knee replacement can reduce in-hospital and 90-day postoperative complications and improve patient health, but it does not reduce the risk of needing a revision surgery, report researchers.
Study finds no benefit, but possible harm, from drug used to prevent preterm birthsA drug commonly prescribed to pregnant women with a history of delivering babies early provides no benefit. In fact, this drug may even increase the risk of developing gestational diabetes.
Emotional intelligence helps make better doctorsA study found that pediatric residents had a median score of 110 on an emotional intelligence survey, compared to an average score of 100 in the general population. The physicians scored highest in impulse control, empathy and social responsibility and lowest in assertiveness, flexibility and independence.
Study quantifies effect of 'legacy phosphorus' in reduced water qualityFor decades, phosphorus has accumulated in Wisconsin soils.
