New learning mechanism for individual nerve cells

The traditional view is that learning is based on the strengthening or weakening of the contacts between the nerve cells in the brain. However, this has been challenged by new research findings from Lund University in Sweden. These indicate that there is also a third mechanism – a kind of clock function that gives individual nerve cells the ability to time their reactions. “This means a dramatic i

Genetic test reveals risk of atrial fibrillation and stroke

Many of those who are genetically predisposed to develop atrial fibrillation, which dramatically raises the risk of stroke, can be identified with a blood test. This is shown by new research from Lund University in Sweden. The number of people affected by atrial fibrillation is rising rapidly, partly as a result of the ageing population. Over recent years, a research group at Lund University in Sw

Liquid DNA behind virus attacks

Viruses can convert their DNA from solid to fluid form, which explains how viruses manage to eject DNA into the cells of their victims. This has been shown in two new studies carried out by Lund University in Sweden. Both research studies are about the same discovery made for two different viruses, namely that viruses can convert their DNA to liquid form at the moment of infection. Thanks to this

Study of identical twins reveals type 2 diabetes clues

By studying identical twins, researchers from Lund University in Sweden have identified mechanisms that could be behind the development of type 2 diabetes. This may explain cases where one identical twin develops type 2 diabetes while the other remains healthy. The study involved 14 pairs of identical twins in Sweden and Denmark. One twin had type 2 diabetes and the other was healthy. “Twins are a

Mechanism that repairs brain after stroke discovered

A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institutet in Sweden. The findings have been published in the journal SCIENCE. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen. Many nerve cells d

Disputed theory on Parkinson's origin strengthened

Parkinson's disease may start in the gut Parkinson's disease is strongly linked to the degeneration of the brain’s movement center. In the last decade, the question of where the disease begins has led researchers to a different part of the human anatomy. In 2003, the German neuropathologist Heiko Braak presented a theory suggesting that the disease begins in the gut and spreads to the brain. The i

Personalised treatment for stress-related diabetes

Researchers at Lund University in Sweden are testing a treatment for type 2 diabetes which targets the disease mechanism itself - and not just the symptoms. For the first time, knowledge about the individual patient’s genetic risk profile is being used. The treatment completely restores the capacity to secrete insulin, which is impaired by the risk gene. ”The concept of treatment personalised to t

Shrinking resource margins in Sahel region of Africa

The need for food, animal feed and fuel in the Sahel belt is growing year on year, but supply is not increasing at the same rate. New figures from 22 countries indicate falling availability of resources per capita and a continued risk of famine in areas with low ‘primary production’ from plants. Rising temperatures present an alarming prospect, according to a study from Lund University in Sweden.

Secret wing colours attract female fruit flies

Bright colours appear on a fruit fly’s transparent wings against a dark background as a result of light refraction. Researchers from Lund University in Sweden have now demonstrated that females choose a mate based on the males’ hidden wing colours. “Our experiment shows that this newly-discovered trait is important in female choice in fruit flies, and is the first evidence that wing interference p

BOOK RELEASE: “Empty Labor: Idleness and Workplace Resistance”

Why do people slack off at work? Last year it was revealed that 20 workers at a big Swedish mining company had been slacking off at work by taking turns clocking each other in and out. The scheme had been going on for several years - supposedly costing the company millions of dollars. How is such major slacking possible?

Cold-induced pain linked to the garlic and mustard receptor

Some people experience cold not only as feeling cold, but actually as a painful sensation. This applies even to fairly mild temperatures – anything below 20°C. A group of researchers from Lund University in Sweden have now identified the mechanism in the body that creates this connection between cold and pain. It turns out that it is the same receptor that reacts to the pungent substances in musta

Glassy protein solution may cause eyesight deterioration

Long-sightedness caused by age could be due to proteins in the lens of the eye that are converted from a fluid solution to a solid, glassy state. This has been shown in a study by researchers from institutions including Lund University. Around the age of 40–50, many people find their sight deteriorates and they need to use reading glasses. This age-related long-sightedness is thought to be due to
