Researchers have created a 3-D printed cosmic microwave background -- a map of the oldest light in the universe -- and provided the files for download.
With five simple questions and an inexpensive peak expiratory flow (PEF) meter, primary care clinicians may be able to diagnose many more patients with chronic obstructive pulmonary disease, or COPD, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine. Follow-up studies will help establish if earlier identification and treatment of people with COPD improves quality of life and health outcomes.
Researchers at Brigham and Women's Hospital have found two new potential drug targets for treating arterial diseases such as atherosclerosis. By using proteomics to screen a vast number of molecules, the researchers identified PARP9 and PARP14 -- two members of the PARP family of proteins -- as regulators of macrophage activation, which has been linked to arterial disease by systems biology.
A new probe into why colorectal surgery patients end up back in the hospital after surgery suggests that it has less to do with the hospital or treatment received but rather more determined by patient factors such as race, income, and insurance status. The study underscores the vast challenge in leveling health disparities especially as some hospitals that serve these populations face disproportionately harsh penalties for outcomes directly impacted by such factors.
Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
