First in-depth analysis of primate ovarian aging at single-cell resolution

Due to the modern tendency to postpone childbirth until later in life, a growing number of women are experiencing issues with infertility.

Researchers use new technique to improve the ability to model lung diseases

Using a combination of pluripotent stem cells (cells that can potentially produce any cell or tissue type) and machine learning (artificial intelligence that allows computers to learn automatically), researchers have improved how they generate lung cells.

Advances in tuberculosis research yield immune responses

A new study published in January 2020 in the journal Science Translational Medicine depicts for the first time ever a beautifully detailed map of the way three different species reacts to tuberculosis, based on their genetic and immune differences.

Gene-editing taken to advanced levels in human stem cells

A new study published in the journal Stem Cell Reports in January 2020 reports the use of an adaptation to a commonly used gene editing technology to achieve a more than 900% increase in efficiency.

New genetic screen for Huntington’s disease

Huntington’s disease is a genetic disease that is debilitating and progressive leading to severe brain damage and eventual death. In patients with this autosomal dominant disease, there is presence of a protein called the Huntingtin protein that forms clumps within the brain leading to the symptoms of the disease.

Regulating neuronal lipid metabolism helps axon regeneration after injury, study finds

Typical examples include paralysis due to a spinal cord injury and visual field atrophy or even complete blindness due to optic nerve atrophy in glaucoma patients.

Study maps immune responses to tuberculosis across 3 species

Tuberculosis is one of the world's most vexing public health problems. About 1.5 million people died from this bacterial lung infection in 2018, and the World Health Organization estimates that one-quarter of the world's population -- some 2 billion people, mostly in developing countries -- are infected with the bacteria that causes TB.

Death receptor pathway drives resistance to CAR T cell therapy

Some cancer cells refuse to die, even in the face of powerful cellular immunotherapies like CAR T cell therapy, and new research from the Abramson Cancer Center of the University of Pennsylvania is shedding light on why.

Defective ATP13A2 gene can lead to Parkinson's disease, shows study

Biomedical scientists at KU Leuven have discovered that a defect in the ATP13A2 gene causes cell death by disrupting the cellular transport of polyamines.

Researchers discover new target for repairing heart after heart attack

Billions of cardiac muscle cells are lost during a heart attack. The human heart cannot replenish these lost cells, so the default mechanism of repair is to form a cardiac scar.

Group A streptococcus strains that are less susceptible to commonly used antibiotics identified

Infectious disease scientists identified strains of group A streptococcus that are less susceptible to commonly used antibiotics, a sign that the germ causing strep throat and flesh-eating disease may be moving closer to resistance to penicillin and other related antibiotics known as beta-lactams.

Researchers examine abnormal neuron activity in Rett syndrome

The brain undergoes dramatic change during the first years of life. Its circuits readily rewire as an infant and then child encounters new sights and sounds, taking in the world and learning to understand it. As the child matures and key developmental periods pass, the brain becomes less malleable--but certain experiences create opportunities for parts of the adult brain to rewire and learn again.

Study: 25% of pathogenic bacteria can spread antibiotic resistance directly to peers

Biomedical engineers at Duke University have demonstrated that at least 25 percent of antibiotic-resistant pathogenic bacteria found in clinical settings are capable of spreading their resistance directly to other bacteria.

Study reveals how the gut's protective mechanisms ramp up with food intake

A new study has revealed how the gut's protective mechanisms ramp up significantly with food intake, and at times of the day when mealtimes are anticipated based on regular eating habits.

Interleukin-1-beta-induced chronic inflammation promotes lung cancer metastasis

The study reveals a detailed epigenetic mechanism for how interleukin-1-beta, a common cytokine that helps fight infections during inflammation, plays a critical role in cancer metastasis.

Link between autism and poor cognition

Autistic people are often brilliant, but they may also have poor cognitive skills. The relationship between autism and either condition, inside the brain, has been far from clear. However, now a new study shows that poor cognition in autism could be due to the influence of a small gene fragment.

Japanese researchers identify genetic variations related to specific dietary habits

Researchers at the RIKEN Center for Integrative Medical Sciences in Japan and colleagues at Osaka University have found genetic variations in humans related to specific dietary habits.

Inducing totipotency into stem cells opens new doors for potential cell replacement therapies

Early mammalian development is a highly complex process involving elaborate and highly coordinated biological processes.

Finer particulate matter (PM1) and risk of cardiovascular disease

A new study published in the journal Environmental Science & Technology Letters reports that particulate matter smaller than a single micron in diameter, called PM1, is strongly linked to the occurrence of cardiovascular disease (CVD). This is thought to be due to its higher surface area to volume ratio.

Pre-existing anticancer drug could help treat common form of heart failure

When it comes to finding new treatments for disease, reinventing the wheel is not always necessary - drugs already in use for other conditions may do the job.
