hukommelsesteknik så man husker i længere tid

A Computational Model of Systems memory Reconsolidation and ExtinctionIn the mammalian brain newly acquired memories are dependent on the hippocampus for maintenance and recall, but over time these functions are taken over by the neocortex through a process called memory consolidation. Thus, whereas recent memories are likely to be disrupted in the event of hippocampal damage, older memories are less vulnerable. However, if a consolidated memory is reactivated by a

Internet-connected 'smart' devices are dunces about securityThese days, it's possible to use your phone—and sometimes just your voice—to control everything from your TV to your lights, your thermostat and shades, even your car or medical device. (At least, once you have gadgets that can listen.)

Investment key in adapting to climate change in West AfricaClimate projections for West Africa show that crop yields and grass for livestock grazing are likely to decline in the future. But a new study in the journal Global Environmental Change shows that when ineffective institutions and political instability limit investment in agriculture climate change would have greater impacts on regional food security.

Two new tidal disruption events discoveredIn two recently published scientific papers, an international team of astronomers has presented the detection of two new tidal disruption events (TDEs). Using the Palomar Observatory located near San Diego, California, the researchers discovered flares of radiation which turned out to be TDEs. Their findings were described in papers published online March 2 and 3 on the arXiv pre-print server.

Engineers devise two-way radio on a single chipTwo-way communication requires, of course, both send and receive capabilities. But putting them in the same device requires a filter between the send and receive circuits to provide signal isolation.

Study finds young Latino boys tend to have stable family lives, yet lag on academicsResearchers led by University of Maryland College of Education Professor Natasha Cabrera have found that Latino boys at nine months of age have similar cognitive and social-emotional skills as their peers and live in stable home environments. Yet by preschool, they lag behind their peers on many academic measures that are used as indicators of future success in school and in the workforce.

Zoo rhino killing hints at new European avenue for poachersThis week's brutal killing of a rhino in its enclosure at a French zoo points to a new European frontier for greedy poachers that must be closed as a matter of urgency, environmentalists and officials say.

How stable manure protects against allergiesImproved hygiene has largely eliminated infectious diseases from everyday life. There is, however, a downside to this progress: the number of allergies is growing steadily. If the immune system is not kept busy by bacteria, viruses and worms, it sometimes overreacts to harmless things like pollen.

The sky is the limit for new low-cost 3D printerA research team is in the process of making a 3D printed Tower of Babel using a novel hanging printer. This offers a low-cost solution and increased flexibility to print large volumes.

Traveling through scattering tissue with far less lightMedical applications of light, looking inside human tissue, often are limited by the highly scattering nature of tissue. Intuitively, a lower limit of one photon per camera pixel is assumed. Scientists now demonstrate that the lower limit is actually much lower, thus opening possibilities of going deeper into tissue with less light.

How much sun is good for our health?Researchers have estimated the duration of solar radiation exposure required in order to obtain the recommended doses of vitamin D. While in spring and summer 10 to 20 minutes in the sun are enough, in the winter months almost two hours would be needed, therefore for the vast majority of the population it is difficult to achieve the optimal values. Every year, studies on the benefits of sunbathing

Trauma surgeons show 'profound' racial disparity in Philadelphia gun violenceResearchers argue for more research on firearm injury, including the establishment of a national database on incidents of gun violence. The authors point to recent research showing that in Philadelphia, gun murders and injuries are much more strongly associated with race than neighborhood income levels.

Research lab expands palette for color-changing glassNew nanophotonics research could expand the color palette for companies in the fast-growing market for glass windows that change color at the flick of an electric switch. A team of researchers has used an inexpensive hydrocarbon molecule to create low-voltage, multicolor, electrochromic glass.

fish, selective hunting strategies and a delayed-return lifestyle among ancient foragersA unique trove of bone material from the 9,200 year old coastal settlement Norje Sunnansund in Blekinge, Sweden, has revealed that surprisingly sophisticated hunting strategies were used at the time. One key find was that the early Mesolithic humans practiced so-called selective hunting — seemingly in order to maximize gain and preserve the local population of certain species.

Mechanism underlying size-sorting of rubble on asteroid Itokawa revealedResearchers investigate why pebbles and boulders on asteroid Itokawa's surface occupy separate regions.

Controversial 'liberation therapy' fails to treat multiple sclerosisOpening up narrowed veins from the brain and spinal cord is not effective in treating multiple sclerosis (MS), according to a study. The conclusions about the so-called 'liberation therapy,' which thousands of people with MS have undergone since 2009, represent the most definitive debunking of the claim that patients could achieve dramatic improvements from a one-time medical procedure.

New survey finds 'Peter Pan' radio galaxies that may never grow upA team of astronomers has doubled the number of known young, compact radio galaxies — galaxies powered by newly energized black holes. The improved tally will help astronomers understand the relationship between the size of these radio sources and their age, as well as the nature of the galaxy itself. In particular, it will help astronomers understand why there are so many more young radio galaxi

The proteins that domesticated our genomesScientists have carried out a genomic and evolutionary study of a large and enigmatic family of human proteins, to demonstrate that it is responsible for harnessing the millions of transposable elements in the human genome. The work reveals the largely species-specific gene-regulatory networks that impact all of human biology, in both health and disease.

Silk Road evolved as 'grass-routes' movementNearly 5,000 years ago, long before the vast east-west trade routes of the Great Silk Road were traversed by Marco Polo, the foundations for these trans-Asian interaction networks were being carved by nomads moving herds to lush mountain pastures, suggests new research.

High prevalence, incidence of hypertension among rural Africans living with HIVAbout 12 percent of people living with HIV in rural Tanzania have hypertension at the moment of HIV diagnosis. An additional 10 percent will develop hypertension during the first months of antiretroviral therapy. This represents an incidence 1.5 times higher than that found in Europe or the United States.
