Microbiologists at the University of Texas Health Science Center have discovered a cellular molecule called NOD2 that recognizes two common respiratory viruses and directs cells to mount a defense. The finding holds promise for new therapies against human RSV and influenza A, particularly among vulnerable populations.
Hurricane Bill is bringing heavy rain and strong surf to Nova Scotia, Prince Edward Island, and Newfoundland, with total rainfall expected at 3-5 inches. The storm's powerful thunderstorms are accompanied by a small eye in the midst of cloud-filled imagery.
Scientists found that primary cilia can either suppress or promote basal cell carcinoma, a type of skin cancer. Removing primary cilia from skin cancer cells blocks tumor growth, while boosting cilia function boosts tumor growth.
A study by Jeff Coller and his team reveals that messenger RNA (mRNA) is predominantly degraded on ribosomes, altering the common dogma of how gene expression is controlled within cells. This finding has significant implications for understanding genetic diseases linked to mRNA degradation.
Researchers found that strains of Bacteroides fragilis dupe immune cells into allowing runaway colon tissue inflammation, a precursor to malignant growth. High levels of pStat3 and Th17 activity in infected mice were linked to chronic inflammation and tumor development.
Researchers have successfully modified a human embryonic stem cell line to glow red when it becomes a red blood cell, representing a significant step towards generating mature red blood cells from human stem cells. This breakthrough could aid in tracking the differentiation of embryonic stem cells into specific cell types.
Researchers at UCSF discovered a tiny filament extending from brain cells, known as primary cilia, may play a role in the most common malignant brain tumor in children. The study found that primary cilia are present in some tumors but absent in others, suggesting they may be used by cancer cells to grow.
Researchers at the University of Michigan have identified a novel gene and enzyme that may hold the key to treating idiopathic pulmonary fibrosis, a life-threatening lung disease. The discovery could lead to new treatments for not only pulmonary fibrosis but also other organ-based diseases such as cardiac and kidney fibrosis.
A new study using satellite images found that nearly half of the world's farmed landscapes include significant tree cover, exceeding 10% in over 1 billion hectares. This reveals a vital role of trees in agricultural production globally, providing benefits such as carbon sequestration and nutrition for people.
Researchers captured a one-second image of gigantic jets, which are highly charged meteorological events that flash up to the lower levels of space. The study reveals that these events have comparable electrical charges to conventional lightning, but travel farther and faster due to thinner air.
Researchers at Beth Israel Deaconess Medical Center discovered a genetic link between childhood brain development and adult-onset epilepsy, highlighting the fragility of the brain during early childhood. The study identifies a new pathway controlling neuron circuit maturation, which may lead to new therapies for this condition.
