When calves grow too large in the womb
For a long time an increased growth of calves in the womb and associated consequences generated severe problems for breeders and scientists. Furthermore, many studies had proven that prenatal ...

Despite other challenges, biological difficulties may be the primary obstacle to successful mammalian reproduction and development in orbit, according to new findings by Teruhiko Wakayama and his coll...
Life Sciences | Read moreThree IVF attempts double chances
Around three per cent of all children born in Sweden are test-tube babies resulting from IVF (in vitro fertilisation). "There are considerable discrepancies between the number of cycles o...
Health and Medicine | Read moreThe skeleton: Size matters
Vertebrates have in common a skeleton made of segments, the vertebrae. During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first ...

Researchers at the school have devised a way to efficiently coax the cells to become human germ cells — the precursors of egg and sperm cells — in the laboratory. Unlike previous research, which yield...

Scientists at The Medical College of Wisconsin in Milwaukee have successfully produced liver cells from patients' skin cells opening the possibility of treating a wide range of diseases that affe...

These basic functions often work about the same in people as they do in “model” animals. But if you want to study more sophisticated cognitive processes such as humans’ ability to learn language from ...

The long-standing mystery of the evolution of the turtle shell has been resolved by researchers from the RIKEN Center for Developmental Biology in Kobe. The answer involves a folding process during em...

An examination of a small sample of hair or blood can reveal if a calf has any genetic diseases that will lower the market price. Now, a team of clinicians and diagnosticians and genetic resea...

Researchers at the Johns Hopkins School of Medicine have discovered how one antioxidant protein controls the activity of another protein, critical for the development of spinal cord neurons. The resea...
Life Sciences | Read moreNew hope for patients - Researchers at Hohenstein successfully colonise a textile implant with human stem cells
This characteristic makes them particularly interesting for recreating irreversibly damaged tissues, following a heart attack for example, or in cases of injury to the spinal cord. Researchers...
Life Sciences | Read moreHow stem cells make skin
Stem cells have a unique ability: when they divide, they can either give rise to more stem cells, or to a variety of specialised cell types.In both mice and humans, a layer of cells at the bas...
Life Sciences | Read moreLight at the speed of a bicycle and much more
From the use of adaptive optics to catch perfect images of distant galaxies or detailed representations inside bio-specimens of, for example, mouse embryos, to electromagnetically induced transparency...
Physics and Astronomy | Read moreSecrets of the 4 chambers revealed by reptile hearts
The first genetic link in the evolution of the heart from three-chambered to four-chambered has been found, illuminating part of the puzzle of how birds and mammals became warm-blooded. Frogs ...
