The scientists from I.P. Pavlov Institute of Physiology, Russian Academy of Sciences, have investigated the intellectual abilities of chimpanzees in comparison with the children from a nursery school in Koltushy near St. Petersburg. They asked both to build the pyramids of cubes of different size. The children with the retention of speech development aged from 2 to 7 and two chimpanzees, female (aged 7) and male (aged 11) ones, took part in the experiment. The children and the apes were shown a pyra

An international team of researchers leaded by the Universitat Autònoma de Barcelona have found experimental evidence that the various manifestations of fear in animals are influenced by a specific place or region within the genome. The results, published in the latest edition of Genome Research, were obtained with rats, but the scientists suspect that this research will facilitate an understanding of genetic characteristics and conditioning factors related to fear in humans.

Biotech human breast milk growing but not bottled.

Genetically modified (GM) rice carrying a protein from human breast milk could be used to enhance infant formula, researchers hope. But at present, the protein would not gain approval for use in the United States.

Nutritionists agree that breast milk is best for a baby; infant formula is not as nourishing as the real thing. So for mothers unable to breast-feed, the biotech industry is engineering crops or animals to make huma

Fossil find hints at life of one of our earliest mammalian forebears.

A mouse-sized fossil from 125 million years ago is the earliest known member of the mammal group that includes humans, say researchers.

The animal is a primitive example of today’s dominant mammals. “It’s at the very root of this diverse and incredibly important group,” says palaeontologist Zhe-Xi Luo of the Carnegie Museum of Natural History in Pittsburgh 1 .

Limp lettuce and wilting roses could be a thing of the past, following the identification of a key plant gene by University scientists. The discovery could also improve food shelf life, and help speed up reforestation programmes. Plant scientists Professor Meyer and Dr Elena Zubko have identified the plant gene which produces a specific type of hormones (cytokinins) to counteract ageing, and control shoot production. By enhancing the gene to overproduce cytokinins, they saw dramatic results: a cut pl

Early life of fetus affects organs’ future health.

Sheep stressed in early pregnancy bear lambs with stunted kidneys that predispose them to high blood pressure Australian researchers have shown. The finding adds to growing evidence that early fetal life influences adult health.

Marelyn Wintour of the University of Melbourne subjected 4-week-pregnant ewes to two stressful days by infusing them with the hormone cortisol. Their lambs developed high blood pressure at 5 months o
