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.
Understanding parallels of human and animal parenting can benefit generations to come
Strong evidence now shows that human and animal parenting share many nervous system mechanisms. This is the conclusion of Yerkes National Primate Research Center researchers Larry Young, PhD, and James Rilling, ...
Worker wasps grow visual brains, queens stay in the dark
A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new study indicates that the brain ...
Electric fish may hold answers to better understanding of sensory abilities and movement
The weakly electric fish, so named because it generates a weak electric field, can do some very cool things. Using sensors located all over its body, for example, it can detect prey or predators that interrupt ...
Microbes can influence evolution of their hosts
You are not just yourself. You are also the thousands of microbes that you carry. In fact, they represent an invisible majority that may be more you than you realize.
Birds and humans have similar brain wiring
You may have more in common with a pigeon than you realise, according to research. It shows that humans and birds have brains that are wired in a similar way.
Brain-penetrating particle attacks deadly tumors
(Phys.org) —Scientists have developed a new approach for treating a deadly brain cancer that strikes 15,000 in the United States annually and for which there is no effective long-term therapy. The researchers, ...
Bird's playlist could signal mental strengths and weaknesses
Having the biggest playlist doesn't make a male songbird the brainiest of the bunch, a new study shows.
Researchers identify protein molecule used to maintain adult stem cells in fruit flies
Understanding exactly how stem cells form into specific organs and tissues is the holy grail of regenerative medicine. Now a UC Santa Barbara researcher has added to that body of knowledge by determining ...
Brain size influences development of individual cranial bones
In mammals, embryonic cranial development is modular and step-wise: The individual cranial bones form according to a defined, coordinated schedule. The typical increase in the size of the brain in mammals ...
Giving birth to new insights into brain development and disease
Each one of us is the complex product of nature and nurture, genes and environment. They combine in a myriad of complex ways during embryonic and postnatal development to sculpt our brains and bodies.
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 ...
Nations agree to phase out toxic chemical HBCD
Governments have agreed to phase out the use of the toxic chemical HBCD, and restrict trade in four other dangerous substances, the head of the UN's anti-pollution division said Friday.
Counting the cost of mercury pollution
Cleaning up mercury pollution and reducing prenatal exposure to the neurotoxin methylmercury (MeHg) could save the European Union €10,000 million per year, finds a new study published in BioMed Central's ...
