Cross-linked polymers are structures where large molecular chains are linked together, allowing exceptional mechanical properties and chemical resistance to the final product. However, their modification is not easy. Now, scientists at Tokyo Institute of Technology develop a method that allows the fusion of different polymers together easily, allowing the precise tuning of the properties of the final material by selecting appropriate base polymers and mixing them at the right proportion.
A study funded by the Veterans Administration and directed by researchers at the University of Miami Miller School of Medicine has shown few differences in the profiles of genes that influence cognition between people with schizophrenia, bipolar disorder and the general population. This surprising finding could provide new insights into therapies designed to improve cognition. The study was published in the American Journal of Medical Genetics.
In the Pacific Northwest, the range expansion of Barred Owls has contributed to a conservation crisis for Northern Spotted Owls, which are being displaced from their old-growth forest habitat. How will this interaction between species play out in the Sierra Nevada, where Barred Owls are just starting to move into the range of the California Spotted Owl? New research published in The Condor: Ornithological Applications suggests that wildlife managers may still be able to head off similar problems in critical areas of the Golden State -- if they act now.
Mathematicians, physicists, and materials experts might not spring to mind as the first people to consult about whether you are brewing your coffee right. But a team of such researchers from around the globe--the United States, the United Kingdom, Ireland, Australia, and Switzerland--are challenging common espresso wisdom, finding that fewer coffee beans, ground more coarsely, are the key to a drink that is cheaper to make, more consistent from shot to shot, and just as strong. Their work appears January 22 in the journal Matter.
AMHERST, Mass. - Results of a new epidemiological analysis of more than 108,000 women observed a lower risk of early menopause among women who had at least one pregnancy lasting at least six months and among those who had breastfed their infants. Further, risk was lowest among those who breastfed exclusively. The work is by first author and Ph.D. student Christine Langton, with her advisor Elizabeth Bertone-Johnson at the University of Massachusetts Amherst's School of Public Health and Health Sciences.
Ahead of the European Commission's official launch of 'Europe's Beating Cancer Plan', The Health Policy Partnership and an expert-led steering committee met at the European Parliament in Brussels today to launch a new report, Radioligand therapy: realising the potential of targeted cancer care.
A first-of-its-kind clinical trial involving more than 600 children in Kenya and Tanzania, in which community members were trained to deliver mental health treatment, showed improvement in participants' trauma-related symptoms up to a year after receiving therapy, new research shows.
An international team led by Harvard Medical School scientists has produced the first genome-wide ancient human DNA sequences from west and central Africa.
The data, recovered from four individuals buried at an iconic archaeological site in Cameroon between 3,000 and 8,000 years ago, enhance our understanding of the deep ancestral relationships among populations in sub-Saharan Africa, which remains the region of greatest human diversity today.
When Marie Antoinette was captured during the French Revolution, her hair reportedly turned white overnight. In more recent history, John McCain experienced severe injuries as a prisoner of war during the Vietnam War -- and lost color in his hair.
A group of experts led by Regina Rabinovich and Carlos Chaccour from the Barcelona Institute for Global Health (ISGlobal) has published a roadmap to evaluate - and subsequently implement - ivermectin as a complementary vector control tool against malaria.
