Cancer cells use 'tiny tentacles' to suppress the immune system

To grow and spread, cancer cells must evade the immune system. Investigators from Brigham and Women's Hospital and MIT used the power of nanotechnology to discover a new way that cancer can disarm its would-be cellular attackers ...

Deep learning democratizes nano-scale imaging

Many problems in physical and biological sciences as well as engineering rely on our ability to monitor objects or processes at nano-scale, and fluorescence microscopy has been used for decades as one of our most useful information ...

Newly developed AI shows speed and accuracy in identifying the location and expression of proteins

A new advanced artificial intelligence (AI) system has shown world-leading accuracy and speed in identifying protein patterns within individual cells. The new system, developed at the University of Surrey's Institute for ...

Three-photon microscopy improves biological imaging

(Phys.org)—Scientists may be a step closer to cracking one of the world's most compelling mysteries: the impossible complexity of the brain and its billions of neurons. Cornell researchers have demonstrated a new way of ...

Two Americans, one German win Chemistry Nobel for giving microscope sharper vision

Chemical probe confirms that body makes its own H2S to benefit health

(Phys.org) —A new study confirms directly what scientists previously knew only indirectly: The poisonous "rotten egg" gas hydrogen sulfide is generated by our body's growing cells. Hydrogen sulfide, or H2S, is normally ...

'Volumetric' imaging method reveals chemical content

A "chemical imaging" system that uses a special type of laser beam to penetrate deep into tissue might lead to technologies that eliminate the need to draw blood for analyses including drug testing and early detection of ...

Add-on device converts cell phones into wide-field fluorescent microscopes

UCLA researchers have developed a matchbox-sized attachment that converts a cell phone's camera into a fluorescent microscope.

Helper cells aptly named in battle with invading pathogens

By tracking the previously unknown movements of a set of specialized cells, Whitehead Institute scientists are shedding new light on how the immune system mounts a successful defense against hostile, ever-changing invaders.

DNA can fold into complex shapes to execute new functions

DNA can mimic protein functions by folding into elaborate, three-dimensional structures, according to a study from researchers at Weill Cornell Medicine and the National Heart, Lung, and Blood Institute, part of the National ...
