Scientists now able to view critical aspects of mammalian embryonic development using new technique
A novel approach in the study of the development of mammalian embryos was today reported in the journal Nature Communications. The research, from the laboratory of Professor Magdalena Zernicka-Goetz of the ...
Discovery of plant 'nourishing gene' brings hope for increased crop seed yield and food security
University of Warwick scientists have discovered a "nourishing gene" which controls the transfer of nutrients from plant to seed - a significant step which could help increase global food production.
Hundreds of Natural-Selection Studies Could be Wrong, Study Demonstrates
(PhysOrg.com) -- Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular ...
Nanoparticles may cause DNA damage across a cellular barrier
(PhysOrg.com) -- Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The research, by the University of Bristol, is published ...
Solving the puzzle of Henry VIII
Blood group incompatibility between Henry VIII and his wives could have driven the Tudor king's reproductive woes, and a genetic condition related to his suspected blood group could also explain Henry's dramatic ...
Study: Mom's blood test can reveal Down syndrome
Scientists in Europe report they were able to diagnose Down syndrome prenatally by giving a simple blood test to pregnant women, an approach that might one day help them avoid the more extensive procedure used now to detect ...
Do we clamp the umbilical cord too soon?
The timing of umbilical cord clamping at birth should be delayed just a few minutes longer, suggest researchers at the University of South Florida's Center of Excellence for Aging and Brain Repair.
Blood pressure breakthrough holds real hope for treatment of pre-eclampsia
Scientists have discovered a mechanism which raises blood pressure in pre-eclampsia, a potentially deadly condition which occurs during pregnancy.
Proper cell–cell interactions are required for the cells of early embryos to develop normally
Some 50 years have passed since scientists first proposed the so-called 'inside–outside model' of development, which holds that the inner cells of the early embryo eventually form all the definitive structures ...
Rewinding development: A step forward for stem cell research
Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta ...
Study sheds light into the nature of embryonic stem cells
New insight into what stem cells are and how they behave could help scientists to grow cells that form different tissues.
Length of pregnancy influenced by placenta structure
The nine-month pregnancy in humans is influenced by the structure of the placenta, according to new research into the evolution of reproduction in mammals which ends a 100-year mystery.
Brooding fishes take up nutrients from their own children
In the pipefish, the male cares for the offspring. Apart from the ones he sucks the life out of. The discovery of filial cannibalism in the pipefish is now creating a stir in the research world.
Scientists discover new source for harvesting stem cells
A groundbreaking study conducted by Children's Hospital & Research Center Oakland is the first to reveal a new avenue for harvesting stem cells from a woman's placenta, or more specifically the discarded placentas ...
