Loneliness linked to higher risk of heart disease and stroke and susceptibility to infection

Interactions with friends and family may keep us healthy because they boost our immune system and reduce our risk of diseases such as heart disease, stroke and type 2 diabetes, new research suggests. Researchers drew this conclusion after studying proteins from blood samples taken from over 42,000 adults recruited to the UK Biobank.

The carbon in our bodies probably left the galaxy and came back on cosmic 'conveyer belt'

Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

Scientists unveil surprising human vs mouse differences in a major cancer immunotherapy target

Much of our knowledge of the protein PD-1, a leading cancer treatment target, comes from studies in mice. In a comprehensive assessment of PD-1, researchers have found that PD-1 in mice is significantly weaker than the human version, providing new information on how cancer treatments are developed.

New nanocrystal material a key step toward faster, more energy-efficient computing

Chemistry researchers have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again.

Advanced imaging uncovers hidden metastases in high-risk prostate cancer cases

A new study has found that many cases of high-risk nonmetastatic hormone-sensitive prostate cancer may be more advanced than previously thought.

Oldest-known evolutionary 'arms race'

A new study presents what is believed to be the oldest known example in the fossil record of an evolutionary arms race. These 517-million-year-old predator-prey interactions occurred in the ocean covering what is now South Australia between a small, shelled animal distantly related to brachiopods and an unknown marine animal capable of piercing its shell.
