Coffee and tea during pregnancy affect fetal growth Drinking just two cups of coffee a day is associated with the risk of low birth weight. Researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, have conducted a study on 59,000 women in collaboration with the Norwegian Institute of Public Health.

Mom's placenta reflects her exposure to stress and impacts offsprings' brains The mammalian placenta is more than just a filter through which nutrition and oxygen are passed from a mother to her unborn child. According to a new study by a research group from the University of Pennsylvania School of Veterinary Medicine, if a mother is exposed to stress during pregnancy, her placenta translates that experience to her fetus by altering levels of a protein that a

Environmental combination favors schizophrenia The interplay between an infection during pregnancy and stress in puberty plays a key role in the development of schizophrenia, as behaviourists from ETH Zurich demonstrate in a mouse model. However, there is no need to panic.

DNA's twisted communication During embryo development, genes are dynamically, and very precisely, switched on and off to confer different properties to different cells and build a well-proportioned and healthy animal. Fgf8 is one of the key genes in this process, controlling in particular the growth of the limbs and the formation of the different regions of the brain. Researchers at EMBL have elucidated how Fgf8 in mammal em

Action video games boost reading skills Much to the chagrin of parents who think their kids should spend less time playing video games and more time studying, time spent playing action video games can actually make dyslexic children read better. In fact, 12 hours of video game play did more for reading skills than is normally achieved with a year of spontaneous reading development or demanding traditional reading treatments.

Eating junk food while pregnant may make your child a junk food addict Here's another reason why a healthy diet during pregnancy is critical to the future health of your children: New research published in the March 2013 issue of The FASEB Journal, suggests that pregnant mothers who consume junk food actually cause changes in the development of the opioid signaling pathway in the brains of their unborn children. This change results in the babies b

Prenatal DHA reduces early preterm birth, low birth weight University of Kansas researchers have found that the infants of mothers who were given 600 milligrams of the omega-3 fatty acid DHA during pregnancy weighed more at birth and were less likely to be very low birth weight and born before 34 weeks gestation than infants of mothers who were given a placebo. This result greatly strengthens the case for using the dietary supplement during pre

They have produced a mutant lacking the ancient bacterial Shewanella-like protein phosphatase known as SHLP1 (pronounced shelph). This mutant is unable to complete its complex life cycle and is arrested in its development in the mosquito. The discovery could help in the

New type of gene that regulates tumor suppressor PTEN identified Researchers at Karolinska Institutet in Sweden have identified a new so-called pseudogene that regulates the tumour-suppressing PTEN gene. They hope that this pseudogene will be able to control PTEN to reverse the tumour process, make the cancer tumour more sensitive to chemotherapy and to prevent the development of resistance. The findings, which are published in the scientific journal Nature

Human heart tissue development slower than other mammals The walls of the human heart are a disorganised jumble of tissue until relatively late in pregnancy despite having the shape of a fully functioning heart, according to a pioneering study.
A University of Leeds-led team developing the first comprehensive model of human heart development using observations of living foetal hearts found surprising differences from existing animal models.

How the whale got its teeth Whales are mammals, but they don't look like the mammals living around us, as they have a triangular fluke for tail, no hind legs and no body hair. And inside their mouths, their teeth are unfamiliar too – being much simpler and 'peg like'. A multidisciplinary team of researchers have now married together the fossil record and the embryonic development process to investigate how the whale got its

Current therapy against HCV is suboptimal. Daclatasvir, a direct acting antiviral (DAA) agent in development for the treatment of HCV, targets one of the HCV proteins (i.e., NS5A) and causes the fastest viral decline (within 12 hours of treatment) ever seen w

'Activating' RNA takes DNA on a loop through time and space Long segments of RNA— encoded in our DNA but not translated into protein—are key to physically manipulating DNA in order to activate certain genes, say researchers at The Wistar Institute. These non-coding RNA-activators (ncRNA-a) have a crucial role in turning genes on and off during early embryonic development, researchers say, and have also been connected with diseases, including some cancers,
