Simple physics may play key role in helping the body to fight infection

Simple physics may play a larger role than previously thought in helping control key bodily processes - such as how the body fights infection.

Penn investigators devise new method to map 'transcriptome'

A new way of mapping the "transcriptome" -- the collection of RNA read-outs that are expressed by a cell's active genes -- has been devised by researchers from the Perelman School of Medicine at the University of Pennsylvania.

Rockefeller University researchers identify new mechanism involved in early stem cell development

Stem cells work throughout our lives as a sort of handyman, repairing damaged tissues and renewing some normal ones, like the skin we shed. Scientists have come to understand much about how stem cells function when we are adults, but less is known about where these stem cells come from to begin with, as an embryo is developing.

Discovery may pave way for more effective treatments for pandemics, seasonal flu

Scientists at Imperial College London have discovered how flu viruses 'hijack' cell machinery when they infect the body. The findings, published in the journal Nature, may pave the way for more effective antiviral treatments for pandemics and for seasonal flu, which infects over 800 million people worldwide every year.

Gene therapy shows promise in children with Wiskott-Aldrich syndrome

Researchers reported promising preliminary outcomes for the first four children enrolled in a U.S. gene therapy trial for Wiskott-Aldrich syndrome (WAS), a life-threatening genetic blood and immune disorder, at the 57th annual meeting of the American Society of Hematology (abstract #260).

Oxford professor wins Heinrich Wieland Prize for pioneering method that helps control nerve cells with light

Gero Miesenböck was the first to insert a light-controlled on/off switch into brain cells. His pioneering method allows scientists to switch nerve cells on and off selectively and observe how the behaviour of, for example, fruit flies or mice changes as a result. In this way, researchers can learn in a step-by-step process what behaviour the studied brain circuits control and what goes awry in disease. For his method, hailed as a "breakthrough of the decade," Professor Gero Miesenböck of the University of Oxford will receive the 100,000-euro Heinrich Wieland Prize of the Boehringer Ingelheim Foundation in Munich on November 6, 2015.

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

IDT’s innovative Alt-R CRISPR-Cas9 System improves genome editing potency, reduces cell toxicity

Integrated DNA Technologies, introduces a new approach to CRISPR—its innovative Alt-R CRISPR-Cas9 System, based on the naturally occurring S. pyogenes CRISPR RNA system.

Liposomal sizing and the Coulter principle: an interview with Professor Melvin E. Klegerman

For about the last 25 years, the cardiology group here have been developing a platform technology for both the diagnosis and treatment of atherosclerosis.

Set of genes identified in human genome essential for survival, proliferation of human cell lines

Using two complementary analytical approaches, scientists at Whitehead Institute and Broad Institute of MIT and Harvard have for the first time identified the universe of genes in the human genome essential for the survival and proliferation of human cell lines or cultured human cells.

New study on deep-diving whales may help researchers create synthetic blood for human trauma patients

The ultra-stable properties of the proteins that allow deep-diving whales to remain active while holding their breath for up to two hours could help Rice University biochemist John Olson and his colleagues finish a 20-year quest to create lifesaving synthetic blood for human trauma patients.

Protein-based modular system could help detect viral infection or kill cancer cells

MIT biological engineers have developed a modular system of proteins that can detect a particular DNA sequence in a cell and then trigger a specific response, such as cell death.

New study highlights gap in scientific knowledge about some diabetes drugs

A gap in scientific knowledge about a family of drugs that are used to treat Type 2 diabetes has been highlighted in a new study.

Location-dependent pattern in cilia length in mouse nasal cavity affects sensitivity to odors

Like the hairs they resemble, cilia come in all lengths, from short to long. But unlike the hair on our heads, the length of sensory cilia on nerve cells in our noses is of far more than merely cosmetic significance. A team of researchers from the Perelman School of Medicine at the University of Pennsylvania found a location-dependent pattern in cilia length in the mouse nasal cavity that affects sensitivity to odors.

Virginia Tech scientists discover new treatments to target antibiotic-resistant bacteria

Virginia Tech researchers have discovered a new group of antibiotics that may provide relief to some of the more than 2 million people in the United States affected by antibiotic resistance.

New technology may allow mass production of flu vaccines

Vaccines to protect against an avian influenza pandemic as well as seasonal flu may be mass produced more quickly and efficiently using technology described today (Sept. 2) by researchers at the University of Wisconsin-Madison in the journal Nature Communications.

Studies using yeast genetics provide new insights into cell-division cycle

Studies using yeast genetics have provided new, fundamental insights into the cell-division cycle, researchers at the University of Michigan Life Sciences Institute report.

FAU researchers identify endogenous process that controls reproduction of cardiac muscle cells

Heart failure is the most common cause of death worldwide. The main reason for this is that damage to the human heart causes cardiac muscle cells to die, which in turn leads to reduced heart function and death. However, this is not the case for zebrafish or amphibians. If their hearts become damaged and cardiac muscle cells die, their remaining cardiac muscle cells can reproduce, allowing the heart to regenerate.

Reducing incorrect gene expression can extend lifespan of cells

Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such "noise" extends lifespan in these organisms. The team published their findings this month in Genes & Development.

Understanding the workings of error correction mechanism in cell division

Cell biologists led by Thomas Maresca at the University of Massachusetts Amherst, with collaborators elsewhere, report an advance in understanding the workings of an error correction mechanism that helps cells detect and correct mistakes in cell division early enough to prevent chromosome mis-segregation and aneuploidy, that is, having too many or too few chromosomes.
