Evolving a bigger brain with human DNA
The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger ...
Scientists generate "mini-kidney" structures from human stem cells
(Phys.org) —Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better ...
Fluctuating environment may have driven human evolution
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
Single gene controls fish brain size and intelligence
A single gene called Angiopoietin-1 (Ang-1) drives brain size and intelligence in fish according to a new study by researchers at UCL, Stockholm University and University of Helsinki.
Softbank's childlike robot with 'heart' set to go on sale
Technology company Softbank's Pepper robot is going on sale in Japan on Saturday, equipped with a "heart" designed to not only recognize human emotions but react with simulations of anger, joy and irritation.
Ecologist trio calls for efforts to mitigate human impact on flying animals
Viral proteins may regulate human embryonic development
A fertilized human egg may seem like the ultimate blank slate. But within days of fertilization, the growing mass of cells activates not only human genes but also viral DNA lingering in the human genome from ...
Cell biologists discover on-off switch for key stem cell gene
Consider the relationship between an air traffic controller and a pilot. The pilot gets the passengers to their destination, but the air traffic controller decides when the plane can take off and when it ...
Gifted men and women define success differently, 40-year study says
(Phys.org) —Researchers spent four decades studying a group of mathematically talented adolescents, finding that by mid-life they were extraordinarily accomplished and enjoyed a high level of life satisfaction.
Evolutionary tools improve prospects for sustainable development
Solving societal challenges in food security, emerging diseases and biodiversity loss will require evolutionary thinking in order to be effective in the long run. Inattention to this will only lead to greater ...
Fruit flies help scientists uncover genes responsible for human communication
The evolution of language in humans continues to perplex scientists and linguists who study how humans learn to communicate. Considered by some as "operant learning," this multi-tiered trait involves many ...
New cell line should accelerate embryonic stem cell research
Researchers at the University of Washington have successfully created a line of human embryonic stem cells that have the ability to develop into a far broader range of tissues than most existing cell lines.
By blocking key signal, researchers maintain embryonic stem cells in vital, undifferentiated state
In a paper published in this week's Online Early Edition of the Proceedings of the National Academy of Sciences, researchers from the University of California, San Diego School of Medicine identify a key gene receptor and si ...
Are gifted children getting lost in the shuffle? 30-year study reveals clues to the exceptional child's journey
(Phys.org) —Gifted children are likely to be the next generation's innovators and leaders—yet the exceptionally smart are often invisible in the classroom, lacking the curricula, teacher input and external ...
