Analyzing embryo movements in uteruslike environments could offer clues to improving the success rate of in vitro ...
Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the ...
Scientists have discovered a sexual reproduction process in microalgae that helps them to better understand algae and plant evolution. Their discovery could lead to new industrial applications for ...
The main difficulties were the slow adsorption of the virus to the reproductive cells, the relatively high proportion of free (vital) virus particles not taking part in the reproduction process ...
A recent study published in Clinical Anatomy found that the clitoris isn't just for sexual pleasure. The clitoris may act as a crucial part of the reproduction process, sending signals to the ...
Reproduction is the process by which organisms (parents) produce new organisms (offspring.) There are two types of reproduction: asexual and sexual.
Self-reproduction, a defining property of living organisms, has been largely ignored by engineers and materials scientists, who are more interested in one-off self-assembly. But there are times ...
A 100-million-year old piece of amber has been discovered which reveals the oldest evidence of sexual reproduction in a flowering plant -- a cluster of 18 tiny flowers from the Cretaceous Period ...
Researchers have previously noted that, in at least one species, this process often stalls while the two cells are still connected by a slender thread--and they were unsure how the cells completed ...
The reproduction process is essentially the same in humans, animals and most plants. Both female and male organisms are required to contribute to the phenomenon.
A recent study claims that the female clitoris is vital for the reproduction process. The review notes that stimulating the clitoris activates the brain to cause a combination of changes in the ...
