Scientists found evidence of periodic changes in equatorial trade winds and warm tropical waters, which warmed the North Atlantic region and triggered melting along massive ice sheets. The research links climate phenomena at the top and middle of the globe, proposing a mechanism involving the release of warm water pools.
Researchers found that patients who received chemotherapy and radiation after surgery lived longer than those who did not. Additionally, 7% of patients had inherited mutations in the BRCA2 gene, which is linked to breast and ovarian cancer.
Western Europe is narrowing the gap with the US in R&D investment, spending over $20 billion on research in Western European institutions. The region also outproduces the US in producing Ph.D.s in natural sciences and engineering, with a 38% increase in doctoral degrees awarded in NS&E fields.
Researchers at the University of Washington have discovered a correlation between lightning frequency and rainfall, which could lead to a new method for tracking precipitation in remote regions. The connection is thought to be due to ice particles that transfer electric charge when colliding in clouds.
Researchers found that a left-handed woman's writing ability was controlled solely by her right hemisphere, separate from her reading and speaking abilities. This discovery provides evidence that human brains have adapted older operations for written language.
