Neandertal genes alter neurodevelopment in modern human brain organoids
Building modern human brain organoids with the Neanderthal variant of a gene has provided a glimpse into the way substitutions in this gene impacted our species' evolution. (2021-02-11)

Genetics of schizophrenia in South African Xhosa informs understanding for all human populations
In the first genetic analysis of schizophrenia in an ancestral African population, the South African Xhosa, researchers report that individuals with schizophrenia are more likely to carry rare damaging genetic mutations than those who are well. (2020-01-30)

Organoids open window into development of human forebrain
Brain region-specific organoids have allowed researchers to peer inside the complex programming of human forebrain development, a process once inaccessible to molecular study. (2020-01-23)

Diet-related changes in human bite spread new speech sounds
Contradicting the theory that the range of human sounds has remained fixed throughout human history, a new study reports that sounds such as 'f' and 'v', both common in many modern languages, are a relatively recent development -- one brought about by diet-induced changes in the human bite. (2019-03-14)

Seeing is believing: Monitoring real time changes during cell division
Scientist have cast new light on the behaviour of tiny hair-like structures called cilia found on almost every cell in the body. Cilia play important roles in human development and disease. Akin to tiny antennae, they act as cell timers keeping the brakes on cell division until the right growth cues are received. Malfunction of cilia leads to many human diseases such as polycystic kidney disease and cancer. (2018-11-19)

Lab-grown eggs could pave way towards new fertility treatments
Human eggs have been developed in the lab from their earliest stage to full maturity, in a study that could lead to improved fertility treatments. (2018-02-08)

Experts seek to jump-start vaccine development
Although many infectious diseases lack vaccines, current vaccine research is limited, primarily due to an understandable but unfortunate lack of commercial interest. (2017-02-23)

Katherine High talks gene therapy progress for hemophilia & inherited retinopathies
Gene therapy has shown some of its most promising early results in treating patients with hemophilia and inherited retinal disorders that cause vision loss and blindness, both important research and drug development targets during the career of Katherine High, M.D., President and Chief Scientific Officer of Spark Therapeutics. (2017-01-04)

Understanding X-chromosome silencing in humans
Researchers have discovered new insights into how one of the two X-chromosomes is silenced during the development of female human embryos and also in lab-grown stem cells. X-chromosome silencing is essential for proper development and these findings are important for understanding how the activity of the X-chromosome is regulated to ensure the healthy development of human embryos. (2016-12-15)

New genes linked with bigger brains identified
A number of new links between families of genes and brain size have been identified by UK scientists, opening up a whole new avenue of research to better understand brain development and diseases like dementia. (2016-10-04)

Grant to The Jackson Laboratory for Gene Expression Database
The Jackson Laboratory's Gene Expression Database (GXD), an open resource for the international biomedical research community, will receive a total of $10.5 million in support over the next five years from the Eunice Kennedy Shriver National Institute of Child Health & Human Development. (2016-06-30)

Splitting human embryos to produce twins for IVF may not be viable
Human twin embryos created in the laboratory by splitting single embryos into two using a common method known as blastomere biopsy may be unsuitable both for IVF and for research purposes, according to a new study led by King's College London. (2015-10-21)

The story of what makes us all unique
Each human being is unique with distinct ways of thinking, acting, speaking and moving, all of which change across the life time. Accounting for this requires demonstrating how people make sense of what happens to them, to describe how they develop and change and how their life paths become what they are. (2013-12-10)

Researchers identify fundamental differences between human cancers and genetically engineered mouse models of cancer
Researchers from the Fred Hutchinson Cancer Research Center in Seattle, WA have taken a closer look at existing mouse models of cancer, specifically comparing them to human cancer samples. These genetically engineered mouse models (which usually either overexpress a cancer-causing gene--or (2013-12-05)

Evolution's toolkit seen in developing hands and arms
Thousands of sequences that control genes are active in the developing human limb and may have driven the evolution of the human hand and foot, a comparative genomics study led by Yale School of Medicine researchers has found. (2013-07-03)

Researchers identify key player in the genesis of human intestinal immunity
Better treatments for people suffering from compromised intestinal immunity may emerge from a small-animal model of human intestinal immune development. (2013-06-20)

VTT brings top metabolics experts to Finland
VTT is seeking to create new development paths towards a healthier life. New opportunities created by metabolics in the fields of diagnostics, medical development, industrial biotechnology and environmental technology have been a part of VTT research for almost 10 years. (2011-10-21)

New method for making human-based gelatin
Scientists are reporting development of a new approach for producing large quantities of human-derived gelatin that could become a substitute for some of the 300,000 tons of animal-based gelatin produced annually for gelatin-type desserts, marshmallows, candy and innumerable other products. Their study appears in ACS's Journal of Agriculture and Food Chemistry. (2011-07-13)

Penn State to focus on obesity prevention training
Sustainable, comprehensive and problem-based training to prevent child obesity will now be possible thanks to a $4.5 million, five-year grant from the US Department of Agriculture. (2011-05-04)

Many factors contribute to adolescents' decision-making autonomy
Decision-making within families is an important way for young people to gain independence and responsibility, and adolescence is a time of increasing autonomy. A longitudinal study by Penn State researchers in the College of Health and Human Development concludes that teens have more say in certain areas than in others, and that some teens have more autonomy than others. (2010-03-25)

New brain tumor model developed
A collaboration of researchers, led by Dr. Martine Roussel (St. Jude Children's Research Hospital), has developed a novel mouse model of medulloblastoma -- the most prevalent malignant pediatric brain tumor -- that the researchers hope will more accurately represent the genetic changes involved in human brain tumor development. (2005-10-30)

Human embryonic stem cells promising for replacement of blood supply
Researchers at the University of Minnesota Stem Cell Institute are one step closer to understanding how blood cells develop through the use of human embryonic stem cells. The research better defines the conditions under which blood cell development occurs, making the process easier to replicate. The findings are published in the October issue of Experimental Hematology. (2004-10-29)

The case for a global development organisation
As the World Summit on Sustainable Development approaches in Johannesburg, South Africa, a Commentary in this week's issue by Lancet Editor Richard Horton argues the case for a new Global Development Organisation to be accountable for human development. (2002-08-22)

Scientists discover gene required for testis development
In the October issue of Genes & Development, Christopher Raymond and colleagues detail their discovery that the gene, Dmrt1, is essential for normal mammalian testis development. This work provides the first functional evidence that Dmrt1 is required for male sexual development in vertebrates, and helps elucidate the basis of human testicular degeneration syndrome. (2000-10-04)
