New tools illuminate mechanisms behind overlooked cellular components’ critical roles

In two papers published in the journal Cell, researchers from multiple Princeton departments report on the conditions that lead to the formation of membraneless organelles and the impact that the formation has on cellular DNA. Clifford Brangwynne, associate professor of chemical and biological engineering and leader of the research teams, said the […]

The long and short of CDK12

Mutations in the BRCA1 and BRCA2 genes pose a serious risk for breast and ovarian cancer because they endanger the genomic stability of a cell by interfering with homologous recombination repair (HR), a key mechanism for accurately repairing harmful double-stranded breaks in DNA. Without the ability to use HR to […]

New drug combination could be more effective against melanoma

A class of cancer drugs called protein kinase inhibitors is one of the most effective treatments for melanoma. However, in many cases, tumors eventually become resistant to the drugs and cause a relapse in the patient. A new study from MIT suggests that combining kinase inhibitors with experimental drugs known […]

First Jellyfish Genome Reveals Ancient Beginnings of Complex Body Plan

Jellyfish undergo an amazing metamorphosis, from tiny polyps growing on the seafloor to swimming medusae with stinging tentacles. This shape-shifting has served them well, shepherding jellyfish through more than 500 million years of mass extinctions on Earth. “Whatever they’re doing has really worked for them,” said David Gold, an assistant professor […]

Microglia: Teasing Out Diversity

Immune cells known as microglia have been found to protect the brain from injury and infection and are critical during brain development, helping circuits wire properly. They also seem to play a role in disease—showing up, for example, around brain plaques in people with Alzheimer’s. In an ambitious study, perhaps […]

Plant’s recycling system important in sickness and in health

Reduce, reuse, recycle. Or just stick with recycle. A plant relies on cellular machinery to recycle materials during times of stress, but that same machinery has a remarkable influence on the plant’s metabolism even under healthy growing conditions, according to new research from Washington University in St. Louis. Autophagy is […]

Tiny Mexican tetra fish may be holding secrets to successful heart regeneration

Heart disease kills millions every year. It is one of the leading causes of death, because of how crucial heart is for our survival. However, situation is completely different for some animals. A tiny Mexican tetra fish is able to repair its own heart. Scientists from UCL and the University […]

Researchers identify key players in mysterious process of protein quality control

Proteins are the workhorses of our cells, carrying out essential tasks to keep our cells – and our bodies ­– functioning properly. But proteins can only do their jobs if they fold into the right shape. When a protein mis-folds, the cell can try to salvage the situation by re-folding […]

Scientists identified the key signs that allow doctors to predict how long patients have left to live

Death is something we will all have to go through. It is something inevitable and something we should all be aware of. However, for some of us it is going to come sooner. A new UCL-led study has identified the key signs and symptoms that allow palliative care doctors to […]

Smoking could be linked to schizophrenia and psychosis

You know that smoking is not good for you, but do you know exactly how? Most smokers do not really care to hear about the damaging effects of smoking, although they definitely should remember them. It is not just about an increased risk of lung cancer, yellow teeth, bad smell, […]

Babies don't just kick for nothing – they are mapping their bodies in their brain

Baby kicking in mother‘s belly is somewhat of milestone in his development. Everyone puts their hands on the growing belly trying to feel it move. But scientists from UCL say that there may be more to kicking than previously believed – it may actually serve a very important function. Scientists […]

FDA Approves New Targeted Drug for Leukemia Tested at University of Pennsylvania

The U.S. Food and Drug Administration (FDA) has approved the first ever inhibitor drug specifically approved for treating patients with relapsed or refractory acute myeloid leukemia (AML) with a mutation in the Fms-like tyrosine kinase 3 (FLT3) gene. Patients with these mutations who have relapsed or refractory AML have very […]

It’s not a shock: Better bandage promotes powerful healing

A new, low-cost wound dressing developed by University of Wisconsin–Madison engineers could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient’s own body motions to apply gentle electrical pulses at the site of an injury. In rodent tests, the dressings reduced healing times […]

Five questions with Su-Chun Zhang, forger of brain cells

Su-Chun Zhang, a Waisman Center researcher and UW School of Medicine and Public Health professor of neurology and neuroscience, was the first in the world to craft human brain cells from human embryonic stem (ES) cells, and later from the related induced pluripotent (iPS) cells. In light of the 20th […]

Princeton and Microsoft collaborate to tackle fundamental challenges in microbiology

In this project, Microsoft is helping Princeton to better understand the mechanisms of biofilm formation by providing advanced technology that will greatly extend the type of research analysis capable today. Biofilms — surface-associated communities of bacteria — are the leading cause of microbial infection worldwide and kill as many people […]

Turning stem cells into bone with nanoclay-reinforced hydrogel

More than 50% of women and 20% of men over the age of 50 will experience a bone fracture during their lifetime. One way to prevent these fractures—particularly in the most sensitive parts of the skeleton—is delivery of stem cells by means of an injectable carrier, which safeguards the cells […]

Silent seizures: seeds of Alzheimer’s disease?

It can be frightening to watch a person experiencing an epileptic seizure. But some seizures can’t be seen, and these play a role in a different form of devastation—Alzheimer’s disease (AD)—according to work led by University of Minnesota researcher Keith Vossel. With colleagues at the University of California San Francisco […]

UI study shows neighborhood conditions affect mortality, health outcomes

Does  where you live affect your health? Research has shown that neighborhoods with high socioeconomic deprivation also have higher mortality rates. But, those studies were a snapshot in time and did not consider how changes in socioeconomic deprivation—either positive or negative—corresponded to changes in health. Most research also didn’t track subjects over […]
