Is the ice in Greenland in growing decline?

The study found that Greenland's ice sheets are losing significant amounts of ice at a rate of about 300 billion tons per year. The accelerated loss of ice mass is attributed to both anthropogenic warming and natural processes such as variations in snowfall and ocean currents.

Sexual reproduction only second choice for powdery mildew

Research reveals that powdery mildew fungi favor asexually produced offspring for infection, while sexual reproduction is crucial for adaptation to host defense mechanisms. The study suggests an ancient co-evolutionary history between the fungus and its hosts, highlighting the complex dynamics of plant-fungus interactions.

Scientists discover kill-switch controls immune-suppressing cells

Researchers have uncovered the cell death processes that determine regulatory T cell numbers, which can lead to better treatments for autoimmune diseases. The discovery of Bcl-2 family proteins as determinants of regulatory T cell numbers offers new ways to control these cells and potentially suppress autoimmune disease.

Scientists solve a 14,000-year-old ocean mystery

Researchers found that a transient 'perfect storm' of nutrients and light led to the brief bloom of phytoplankton 14,000 years ago. The study resolves conflicting ideas about the relationship between iron and biological productivity in the North Pacific, with implications for geo-engineering efforts to curb climate change.

NIH scientists find that proteins involved in immunity potentially cause cancer

A set of proteins involved in the body's natural defenses produces a large number of mutations in human DNA, according to a study led by researchers at the National Institutes of Health. In some cancers, these naturally produced mutations can outnumber all other mutations and account for over two-thirds of tumors.

Antiviral enzyme contributes to several forms of cancer, University of Minnesota researchers say

Researchers at the University of Minnesota have discovered that APOBEC3B, a human antiviral enzyme, causes DNA mutations that lead to several types of cancer. The enzyme was found to be significantly elevated in six types of cancer and produced a unique mutational signature that matches the actual mutation pattern in these cancers.
