Scientists have discovered that changes in the amount of ice floating in the polar oceans are causing sea levels to rise — by a mere hair’s breadth today, but possibly much more if melting trends continue.
For the first time, scientists have discovered a way to predict whether women with ductal carcinoma in situ — the most common form of non-invasive breast cancer — are at risk of developing more invasive tumors in later years.

A new study offers a long-awaited explanation for the link between HIV infection and susceptibility to life-threatening nontyphoidal strains of Salmonella. The research goes on to identify targets that could be pursued for Salmonella vaccine development.

A researcher has developed a computer chip that can store an unprecedented amount of data — enough to hold an entire library’s worth of information on a single chip. The new chip stems from a breakthrough in the use of nanodots, or nanoscale magnets, and represents a significant advance in computer-memory technology.

Compared to their neighbors south of the border, Canadians live longer, healthier lives. Research has found this disparity between the two countries, suggesting that America’s lack of universal health care and lower levels of social and economic equality are to blame.

Using neutron beams and atomic-force microscopes, a team of researchers may have resolved a 10-year-old question about an exotic class of “artificial muscles” — how do they work? Their results could influence the design of future specialized robotic tools.

Many of the colon cancer cells that form tumors can be killed by genetically short-circuiting the cells’ ability to absorb a key nutrient, a new study has found. While the findings are encouraging, the test tube study using human colon cancer cells also illustrates the difficulty of defeating these cells, known as cancer stem cells.
Knocking genes out of action allows researchers to learn what genes do by seeing what goes wrong without them. Scientists have now devised a procedure for knocking out genes in nematode worms.

New research shows that antiretroviral therapy (ART) continues to dramatically reduce rates of mortality from HIV infection in high-income countries, such that non-AIDS-related deaths exceed AIDS deaths after approximately four years of taking ART.
