Synthetic molecule suppresses drug cravings with fewer side effects

A new synthetic molecule selectively reduces the physiological rewards of cocaine in mice.

Study may help develop medical implants for diabetic patients

For the first time, a research team led by Martin Fussenegger, a professor at ETH Zurich, has successfully used electric current to directly manipulate gene expression.

New technology can help map immune cells in different types of brain tumors

Removing a malignant brain tumor is a balancing act between protecting the healthy tissue and, at the same time, excising as much tumor tissue as possible.

New insights into recombination of sex chromosomes during meiosis

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life.

Research identifies how neuronal transmission is disrupted in ALS

Patients with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, lose muscle control as nerve cells or neurons in the brain and spinal cord degenerate and can no longer send signals to muscles.

Study provides new strategies for treating different types of cancer

An RNA molecule involved in preventing the formation of tumors can modify its structure and thus regulate the production of proteins in the cell.

New methodology could help differentiate between healthy and cancer cells

Scientists have pioneered the use of whole living cells (that is, human lung adenocarcinoma) in dynamic combinatorial chemistry systems.

Chicken cells show promise for producing more effective human antibodies

Antibodies meant for potential drug applications can be produced quickly in chicken cells cultured in laboratories.

Warwick researchers discover how cells respond to fasting and activate autophagy

As modern life-styles and high-calorie diets drive the UK's obesity levels up, researchers from the University of Warwick have found how cells respond to fasting and activate the process called autophagy, which means a healthier lifestyle can be promoted to help people maintain a healthy body weight.

New CRISPR-Cas9 based method for directed protein evolution

"Directed evolution" is the process by which scientists produce tailor-made proteins for cell biology, physiology and biomedicine in the laboratory.

New technique enables high-resolution visualization of tumor heterogeneity patterns

Malignant tumors consume nutrients and oxygen faster than healthy cells. To do so, they recruit blood vessels in their environment.

New study outlines the mechanisms behind cell fusion

Scientists have known for a decade that cells that fuse with others to perform their essential functions - such as muscle cells that join together to make fibers - form long projections that invade the territory of their fusion partners.

Damped circadian oscillations observed in the absence of KaiA protein in cyanobacterium

Circadian rhythms are driven by a highly autonomous, self-sustaining circadian clock in our cells, telling us when to sleep or wake up in a 24-hour cycle.

Study discovers how protein inhibits tumor development in mice

Proteins are found throughout our cells and regulate a lot of biological processes that are important for our survival.

Nanodevices give unprecedented peek into how cells change with time

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.

New minimally invasive method allows cells to be sampled over time

At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene profiling or protein analysis destroy the cell, study is confined to just that one moment in time, and researchers are unable to return to the cell to examine how things change beyond that snapshot.

The eye launches an immune response in the lens following injury

The lens of the eye is an unusual organ. Unlike most of the body's organs, blood vessels don't reach the lens. If they did, they'd obscure our vision and we wouldn't be able to see. The lack of vasculature led scientists to believe immune cells, which travel via the bloodstream, couldn't get to this part of the body either.

Mechanically rejuvenated fibroblasts show promise in stem cell engineering

Fibroblasts synthesize the collagen, creating the structural framework for animal tissues, and play a significant role in the process of wound healing.
