Glucose-Sensing Neurons May Play a Role in Regulating Blood Sugar

The body's blood glucose level needs to be maintained in a relatively narrow range. It cannot be too high, as it can lead to diabetes, and it cannot be too low because it can cause fainting or even death.

Whole Genome Sequencing More Effective Than Targeted Gene Sequencing in Detecting Genetic Disorders

A new national study, led by researchers at Tufts Medical Center in Boston, has found whole genome sequencing (WGS) to be nearly twice as effective as a targeted gene sequencing test at identifying abnormalities responsible for genetic disorders in newborns and infants.

Revolutionizing Drug Design with Light-Activated Molecular Machines

Cells “talk” to one another to coordinate crucial biological activities such as immune activation, muscle contraction, hormone release, neuronal firing, and digestion using calcium signaling as a primary mechanism.

Genetically Modified iPS Cell Applications for Fabry Disease

iPS cells have had a significant impact on biology and medicine, and they are expected to increase regenerative medicine. Clinical trials with various cell types derived from iPS cells have been performed since 2014 when a sheet of retinal pigment epithelial cells obtained from iPS cells was transplanted into patients with age-related macular degeneration.

Influenza A Viruses Use "Tactical Strikes" to Hijack Host Cells

Influenza A is one of two influenza viruses that fuel costly annual flu seasons and is a near constant threat to humans and many other animals. It’s also responsible for occasional pandemics that, like the one in 1918, leave millions dead and wreak havoc on health systems and wider society.

Elaborate 3D Structures of DNA That Mimics Protein Functions

According to a study from scientists at Weill Cornell Medicine and the National Heart, Lung, and Blood Institute, a division of the National Institutes of Health, DNA can imitate protein activities by folding into complex, three-dimensional structures.

Loss of the Y Chromosome Impairs Body's Ability to Fight Cancer

According to recent Cedars-Sinai Cancer research, as men age, some of their cells lose the very feature that makes them biological males—the Y chromosome—and this loss impairs the body’s ability to fight cancer.

Drones and Other Tech Have Major Roles in Conserving Koalas and Other Species

From drones locating koalas hidden in treetops to recording little penguin acoustics and night-time movements on film, Flinders University researchers have shown the importance of technologies such as cameras and AI to help conservation efforts.

Stem Cell Zoo Uncovers Scaling Laws Governing Species-Specific Development

Pregnancy last around nine months in humans, only 20 days in mice, and up to 17 months in rhinoceroses. Even though many mammalian species go through the same phases of embryo development, the rate of development varies greatly between animals.

Review: Role of Alternative Splicing Defects in Major Neurodegenerative Diseases

Alternative splicing, a clever way a cell generates many different variations of messenger RNAs -; single-stranded RNAs involved in protein synthesis -; and proteins from the same stretch of DNA, plays an important role in molecular biology.

Achieving 3D Printing Inside 'Mini-Organs' Growing in Hydrogels

Scientists from the NIHR Great Ormond Street Hospital Biomedical Research Centre (a collaboration between GOSH and UCL), London, and University of Padova, Italy, have shown for the first time how 3D printing can be achieved inside 'mini-organs' growing in hydrogels -- controlling their shape, activity, and even forcing tissue to grow into 'molds.'
