Early onset of puberty - the EU gets serious

31.03.2005


Children in Europe and other parts of the world are entering puberty at an ever younger age. The reasons for this are unknown, and the EU is now financing a major three-year project called PIONEER in a determined effort to get to the root of the problem. Two Swedish research groups are involved in the project, both from Karolinska Institutet.

The onset of puberty is determined by a string of factors, such as environment, physiology and heredity, but just how they interact remains a mystery. It is also unclear why puberty is starting at ever-younger ages, but scientists think that it can be the result of a combination of environmental factors. PIONEER comprises twelve research groups, all of which will be tackling the puzzle from different angles. Most of the groups are working on the theory that a greater intake of calories has a significant part to play, while others will also be looking at hormone-like substances in the environment. Researchers at KI’s Department of Woman and Child Health, however, will for the most part be studying whether the production of male and female sexual hormones is greater in overfed animals than in undernourished ones.

“It’s important to find out the cause of this problem as the early onset of puberty affects a large number of children and can eventually give rise to new reproductive patterns,” says Professor Olle Söder, vice coordinator of PIONEER at KI. “It’s also been shown that girls who reach puberty early are affected in a way that can have consequences for their future, both socially and financially. It’s also conceivable that early puberty is the outcome of external factors in the environment. It’s therefore important to identify these factors so that we can take whatever action is necessary.”

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
