New tool predicts risk of heart attack in older surgery patients
A tool designed to more accurately predict the risk of heart attack in older patients undergoing non-cardiac surgery works significantly better than traditional risk assessment tools. By having more accurate information, older patients and their physicians can make an informed decision on whether to undergo surgery, UCLA researchers concluded.

3-D 'scaffold' map to help the search for new cancer treatments
Researchers have produced the first three-dimensional (3D) map of a molecular 'scaffold' called SgK223, known to play a critical role in the development and spread of aggressive breast, colon and pancreatic cancers.

Electron microscopy uncovers unexpected connections in fruit fly brain
What was once thought to be a done-and-dusted map of the fruit fly brain has gotten a second look, and researchers have discovered that it's actually not done at all.

Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers.

Chemists have created compounds that can treat glaucoma
Glaucoma is a serious disease associated with increased intraocular pressure which often leads to blindness. One of the ways to treat glaucoma is to reduce aqueous humour secretion in the ciliary body of the eye by suppressing (inhibiting) activity of special enzymes - carbonic anhydrases. Russian scientists have designed new compounds that can effectively reduce intraocular pressure.
