Cell division, minus the cells

Cell division, minus the cells

The process of cell division is central to life. The last stage, when two daughter cells split from each other, has fascinated scientists since the dawn of cell biology in the Victorian era. For just as long, it has been notoriously difficult to study this final step, when the dividing cell creates a furrow before cleaving in two.

Cancer cell fingerprints in the blood may speed up childhood cancer diagnosis

Newly-identified cancer cell fingerprints in the blood could one day help doctors diagnose a range of children's cancers faster and more accurately, according to research* presented at the National Cancer Research Institute (NCRI) Cancer Conference next week.

The researchers, from the University of Cambridge and Addenbrooke's Hospital in Cambridge, found unique molecular fingerprints for 11 types of children's tumours,** which could be used to develop blood tests to diagnose these cancers.

Scientists replicate the tide with two buckets, aquarium tubing, and a pump

Rachel MacTavish is growing salt marsh plants in microcosms that replicate the tide. She assembled them in an outdoor greenhouse at the Sapelo Island National Estuarine Research Reserve in Georgia, USA, with buckets from a hardware store, aquarium tubing, and pumps. Her tidal simulation units could be an important tool for preserving and restoring environmentally important wetlands, because they enable researchers to investigate tidal marsh plant growth in a controlled setting.

Are my muscular dystrophy drugs working?

INDIANAPOLIS -- People with muscular dystrophy could one day assess the effectiveness of their medication with the help of a smartphone-linked device, a new study in mice suggests. The study used a new method to process ultrasound imaging information that could lead to hand-held instruments that provide fast, convenient medical information.

Breaking down DNA by genome

New DNA sequencing technologies have greatly advanced genomic and metagenomic studies in plant biology. Scientists can readily obtain extensive genetic information for any plant species of interest, at a relatively low cost, rapidly accelerating the pace of genome sequencing.

Resveratrol could reverse benefits of being active

Contrary to popular belief, use of the supplement resveratrol (RSV) may not actually enhance the effects of high-intensity interval training (HIIT).

Many news outlets and health blogs have long recommended RSV as a complement to exercise and to enhance performance. However, results from a study by Queen's researcher Brendon Gurd suggest that RSV may actually impede the body's response to training.

Bladderwrack: Tougher than suspected

Decoding the emergence of metastatic cancer stem cells

In the first study of its kind, Rice University researchers have mapped how information flows through the genetic circuits that cause cancer cells to become metastatic. The research reveals a common pattern in the decision-making that allows cancer cells to both migrate and form new tumors. Researchers say the commonality may open the door to new drugs that interfere with the genetic switches that cancer must flip to form both cancer stem cells and circulating tumor cells -- two of the main players in cancer metastasis.
