Depending on which variant of a certain gene a woman has, a coffee consumption rate of at least two-three cups a day can either reduce the total risk of developing breast cancer or delay the onset of cancer. This is shown in new research from Lund University and Malmö University in Sweden.

The effect of coffee is related to estrogens, female sex hormones. Certain metabolic products of these hormones are known to be carcinogenic, and various components of coffee can alter the metabolism so that a woman acquires a better configuration of various estrogens. What’s more, coffee contains caffeine, which also hampers the growth of cancer cells.

A quirky psychological phenomenon known as “grapheme-color synaesthesia” describes individuals who experience vivid colors whenever they see, hear, or think of ordinary letters and digits. A hallmark of synaesthesia is that individuals seem to be idiosyncratic in their experiences. That is, most synesthaetes will consistently see the same colors accompanied with specific graphemes, but few of these experiences appear to be shared with other synesthetes. 

Gondwana was a ‘supercontinent' comprised of Antarctica, South America, Africa, Madagascar, Australia-New Guinea, and New Zealand, as well as Arabia and the Indian subcontinent of the Northern Hemisphere.

It existed between 500 and 180 million years ago but geologists have debated for decades over how it eventually broke up. The two primary camps support a theory claiming the continent separated into many small plates and a second theory believes it broke into a few large pieces.

In a new paper published in ‘Geophysical Journal International’, Dr. Graeme Eagles at the University of London says he has the answer.

Eighteen-year-old Sören Wolf was born with only one hand but when it comes to a prosthetic second one, he's enthusiastic about both the “i-LIMB” and the ”Fluidhand.”

The new “i-LIMB” prosthetic hand developed and distributed by Scottish company “Touch Bionics” has distinct advantages over similar competitive models. Complex electronics and five motors contained in the fingers enable every digit of the i-LIMB to be powered individually. A passive positioning of the thumb enables various grip configurations to be activated. The myoelectric signals from the stump control the prosthetic hand; muscle signals are picked up by electrodes on the skin and transferred to the control electronics in the prosthetic hand.

Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells.

Prior to this, it was necessary to use embryonic stem cells. Their findings are published in the latest issue of the journal Stem Cell Research.

The stem cells are derived from material left over from open-heart operations. Researchers at UMC Utrecht used a simple method to isolate the stem cells from this material and reproduce them in the laboratory, which they then allowed to develop. The cells grew into fully developed heart muscle cells that contract rhythmically, respond to electrical activity, and react to adrenaline.

Andalucia has one of the highest rates of childhood obesity in Spain according to the Action Plan to address childhood obesityPlan Integral de Obesidad Infantil de Andalucia 2007-2012.

Only children from The Canary Islands, Cantabria and Murcia are fatter.

Other data show that in Andalucia the prevalence of overweight and obesity combined is 32% in boys and 31% in girls: however it is much higher among younger children than older children and reaches 40% and 45% respectively in boys and girls aged 6-9 years. This suggests there will be an even greater problem in the future.
