Researchers use 3D electron microscopy to unravel dense networks in the cerebral cortex

Unlike any other organ, our brains contain extremely densely packed networks of membranous cables that are used by our about 86 billion nerve cells for communication amongst each other.

Columbia researchers capture new detailed images of a temperature-sensing molecule

Columbia University researchers have captured new detailed images of a temperature-sensing molecule in its open, intermediate, and closed states.

Discovery about DNA-reeling bacteria can help inform strategies to stop bacterial infection

A new study from Indiana University has revealed a previously unknown role a protein plays in helping bacteria reel in DNA in their environment -- like a fisherman pulling up a catch from the ocean.

New technique reveals how the brain responds to light signals received by the retina

In recent decades, scientists have learned a great deal about how different neurons connect and send signals to each other. But it's been difficult to trace the activity of individual nerve fibers known as axons, some of which can extend from the tip of the toe to the head.

Understanding protein aggregation over time can help decipher early stages of Parkinson's

One of the biggest difficulties in treating Parkinson's disease, a progressive neurodegenerative disorder, is the understanding of when it starts.

Scientists uncover details of antibody response to Ebola virus vaccine

In the recurring, deadly Ebola outbreaks in parts of Africa, today's health workers now have at least some tools to fight the disease: vaccines. Vaccines against Ebola have been administered to over 100,000 people to date, but they are barely out of the experimental stage.

New insight into presynaptic distribution and profile of mitochondria in calyx of Held

The ability to hear relies on neurons to constantly transmit information at very rapid timescales. This rapid rate of information transmission results in intense energetic demands. Within our cells, microscopic power plants called mitochondria provide the main source of energy keeping our bodies moving.

Exploiting the weak spot in pathogenic bacteria to develop new antibiotics

Antibiotics are still the most important weapon for combatting bacterial infections. But medical science is running out of "ammunition" because of more and more frequently occurring resistances.

Mount Sinai researchers discover how DNA polymerase delta duplicates the genome

Mount Sinai researchers have discovered how the enzyme DNA polymerase delta works to duplicate the genome that cells hand down from one generation to the next. In a study published in Nature Structural & Molecular Biology, the team also reported how certain mutations can modulate the activity of this enzyme, leading to cancers and other diseases.

Researchers create new material with antifungal and antitumor properties

A new material with antifungal and antitumor properties has been developed by researchers at the Center for Development of Functional Materials (CDMF), one of the Research, Innovation and Dissemination Centers (RIDCs) supported by São Paulo Research Foundation - FAPESP.

Research reveals why viruses will need to be reclassified and its biotech impact

New research reveals that the way viruses were perceived in terms of their architecture will need to be retooled, because they are actually structured in many more patterns than previously understood.

Researchers identify neural circuit that controls perseverance

Success is no accident: To reach your goal you need perseverance. But where does the motivation come from? An international team of researchers led by scientists from the Technical University of Munich (TUM) has now identified the neural circuit in the brain of fruit flies which makes them perform at their best when searching for food.
