One day, hopefully sooner rather than later, a truly energy-efficient, ultra-low-temperature (ULT) freezer will reach the market. Unfortunately, for now, no technology exists that provides significant gains in efficiency, without compromising unit stability.
An experimental 3-dimensional printed model of the heart may help surgeons treat patients born with complicated heart disorders, according to new research.
Researchers have pioneered a stem cell gene therapy cure for children born with adenosine deaminase (ADA)-deficient severe combined immunodeficiency (SCID), often called "Bubble Baby" disease.
For decades, the mouse has been a mainstay for researchers studying human diseases because the two species share many of the same genes. But now, a comprehensive analysis of the inner workings of the DNA in humans and mice has uncovered some striking differences in the way their genes are controlled.
The spread of Ebola remains "intense" in most of Sierra Leone even as things have improved somewhat in the two other countries hardest hit, the World Health Organization says.
Of all the overfished fish in the seas, luscious, fatty bluefin tuna are among the most threatened. Marine scientist Goro Yamazaki, who is known in this seaside community as "Young Mr. Fish," is working to ensure the species survives.
Research shows that taking a cholesterol-lowering drug for five years in middle age can lower heart and death risks for decades afterward. The benefits seem to grow over time and may last for life.
People with mental health problems are “significantly” more likely to have stroke or heart disease, according to a study unveiled at a recent Canadian Cardiovascular Congress.
In a new study, scientists found that a particular set of cells in a small region of the brain are responsible for memory problems after sleep loss. By selectively increasing levels of a signaling molecule in these cells, the researchers prevented mice from having memory deficits.
The three-dimensional biology company Organovo Holdings Inc. announced the full commercial release of the exVive3D Human Liver Tissue for preclinical drug discovery testing.
Flexible electronic sensors based on paper have the potential to cut the price of a wide range of medical tools. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper.
Blueberries are super stars among health food advocates, who tout the fruit for improving night vision. Scientists have now found reason to doubt that the popular berry helps most healthy people see better in the dark.
A new, low impact low energy laser treatment for patients with early age-related macular degeneration (AMD) has produced positive results by reducing indicators of the disease.
Cleveland Clinic surgeons have replaced nearly the entire face of a middle-aged man severely disfigured in a car accident, the hospital announced.
A coalition of companies and aid groups announced plans Tuesday to test experimental drugs and collect blood plasma from Ebola survivors to treat new victims of the disease in West Africa.
Researchers from the University of Cambridge have developed artificial muscles which can learn and recall specific movements, the first time that motion control and memory have been combined in a synthetic material. Read more...
In a new study looking at mice, researchers have investigated a local clock found in another part of the brain, outside the SCN, known as the tuberomamillary nucleus (TMN).
A team of researchers have used a laser beam trap to examine how drug particles from asthma inhalers behave as they are projected through the air. Their findings could improve the effectiveness of inhalers for the over five million people in the UK suffering from asthma.
A new study from geneticists has found that the DNA replication plan— including where the origin points are and in what order DNA segments get copied- varies from person to person.
New research in flies shows how cells in adult reproductive organs maintain their sexual identity. The study also identified a mutation that can switch the cells’ sexual identity.
Engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications such as sensors for environmental and medical monitoring.
In a long-term study of interactions between chimpanzees in the famous Gombe National Park in Tanzania, researchers have found that males who consistently bully females tend to father more babies with their victims.
Is it possible to change the amount of information the brain can store? Maybe, according to a new international study, which identified a molecule that puts a brake on brain processing and when removed, brain function and memory recall is improved.
A top official with the U.N. health agency says few experimental therapies are currently under development that could effectively treat Ebola.
