Baby fat may be cuddly to new parents but pediatricians are increasingly warning families about serious medical problems resulting from baby fat that never goes away. Type 2 diabetes is on the increase in overweight and obese children in America. According to Cedars-Sinai Medical Center pediatric endocrinologist David Geller, M.D., Ph.D., “Childhood obesity is the primary reason we are seeing such a huge increase in type 2 diabetes in kids today. Clearly there is an inexorable increase in body girth and body mass in our children which needs to be taken seriously in order to avoid a lifetime of physical and psychological problems.”
How serious is the problem of overweight children? According to the New England Journal of Medicine, childhood obesity has reached epidemic proportions with the number of overweight children more than doubling in the last three decades. In California the numbers are even more frightening: more than 25% of the state’s public school children are currently overweight and nearly 40% are unfit according to a study by the California Center for Public Health Advocacy.
Many medical experts agree on the underlying reason for the growing obesity problem among America’s children today, namely the exponential rise in media-related, sedentary activities such as watching television and video tapes/DVDs, surfing the Internet and playing video games. Consider these facts:

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
