Discovery about cell membrane 'blebs' could lead to new ways to fight melanoma

Cell membrane protrusions called blebs that typically signify the end of life for healthy cells do the opposite for melanoma cells, activating processes in these cells that help them to survive and spread, a UT Southwestern study suggests.

Researchers synthesize fluorescent molecularly imprinted polymeric nanoparticles to detect neurotransmitters

The animal brain consists of tens of billions of neurons or nerve cells that perform complex tasks like processing emotions, learning, and making judgments by communicating with each other via neurotransmitters.

New model shows how the 'good genes' can cause a population to collapse

Males of a species evolving traits for sexual conflict can cause problems for females, and, ultimately, the whole population.

New ghost imaging algorithm produces higher-resolution image reconstruction with better contrast

Although electron microscopy can already reveal details as small as one nanometer, ongoing research seeks to break through barriers limiting image quality and reducing the optical dose on the samples. Aberration is a common problem in electron microscopy that can reduce the resolution and quality of the images produced.

Gene mutation capable of regulating pain discovered

Pain afflicts at least 1.5 billion people worldwide, and despite the availability of various painkilling drugs, not all forms of pain are treatable.

New method enables direct observation of bee brains

An international team of bee researchers involving Heinrich Heine University Düsseldorf has integrated a calcium sensor into honey bees to enable the study of neural information processing including response to odors.

New way to carry drugs across the blood-brain barrier using nanoparticles

Brain tumors are notoriously hard to treat. One reason is the challenge posed by the blood-brain barrier, a network of blood vessels and tissue with closely spaced cells.

Genome editing could help save rice crops threatened by climate change

A review of gene editing techniques suggests that the CRISPR/Cas (clustered regularly interspaced short palindromic repeats/Cas) method could be a possible 'savior' for rice crops threatened by climate change and high food demand.

Astrocytes exhibit stronger acid response with REM sleep in epileptic mice

Researchers at Tohoku University have shown that astrocytes - star-shaped glial cells that control the local ionic and metabotropic environment of the brain - exhibit an acid response with REM sleep in mice.

Reprogrammed tumor cells could teach the body's immune system to fight cancer

Some cities fight gangs with ex-members who educate kids and starve gangs of new recruits. Stanford Medicine researchers have done something similar with cancer — altering cancer cells so that they teach the body's immune system to fight the very cancer the cells came from.
