A study published today in the journal Arthritis Research & Therapy reveals that there is a significant genetic component to the occurrence and severity of bone marrow lesions in the tibia and femur. The study also shows that bone marrow lesions are more common in men and increase with age and weight.
Guangju Zhai, from St Thomas’ Hospital, London, UK and colleagues from institutions in Australia studied 115 siblings from 48 families with a history of osteoarthritis. Zhai et al. used magnetic resonance imaging (MRI) to assess bone marrow lesions in the subjects. The authors then calculated the heritability estimates - or the extent to which they are hereditary - for bone marrow lesions in lateral and medial tibia and femur.
The results of Zhai et al.’s study show that the heritability estimate was 99% for the prevalence of bone marrow lesions in both lateral and medial compartments of the bones. The heritability estimates for the severity of bone marrow lesions are 53% for lateral bones and 65% for medial bones, after adjustment for age, sex, height, weight, muscle strength, knee pain and knee alignment.
The authors conclude that further studies to identify the gene(s) responsible for bone marrow lesions may help in the prevention and management of knee pain in osteoarthritis, the most common form of arthritis.

New discoveries predict ability to forecast dementia from single molecule

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
