Researchers develop flood-tolerant California rice

...sia in order to produce new lines of rice that can grow in flood-prone areas," she said. In the future, Bailey-Serres and colleagues plan to work on developing crops that are resistant to multiple stresses. "For example, we'd like to develop rice that is both submergence and salt tolerant," she said, "...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

Cigarette smoke blocks cell repair mechanism, University of Florida study shows

...that helps them live long, spread to new sites and grow resistant to chemotherapy. Narayan's team has previously studied cells that were exposed to the chemicals found in cigarette smoke yet did not die. In general, about two-thirds of these cells will be growth-retarded, and some actually acquire cance...

Johns hopkins researchers find link between cell's energy use and genome health

...even though they are single-celled organisms, they grow quickly, are easy to analyze in the lab, and contain many genes and biological processes present in other animals, including humans. For example, like all animal cells, yeast use sugar as an energy source. To harvest the energy contained in sugar,...

Mass. General study finds potential ovarian cancer stem cells

...ct like stem cells, driving the tumor's ability to grow and spread. If some of these specialized cells escaped destruction by chemotherapy or radiation, the tumor would be able to recur quickly, often in a form resistant to chemotherapy. Similar cancer stem cells have been previously identified in leuke...

MIT sheds light on how tumor cells form

...lar Biology Organization (EMBO). Tumor cells that grow aggressively often have an irregular number of chromosomes, the structures in cells that carry genetic information. The normal number of chromosomes in a human cell is 46, or 23 pairs. Aggressive tumor cells often have fewer or more than 23 pairs of ...

Food-crop yields in future greenhouse-gas conditions lower than expected

...SoyFACE project at Illinois, allows researchers to grow crops in open-air fields, with elevated levels of carbon dioxide simulating the composition of the atmosphere projected for the year 2050. SoyFACE has added a unique element by introducing surface-level ozone, which also is rising. Ozone is toxic to ...

New lab technique churns out fungus' potential cancer fighter

...K. Boeckman, professor of chemistry. "You either grow the fungus that makes it, or you go through a complicated chemical synthesis process that still yields only a minute amount," he says. "Now, after five years of effort, we've worked out a process that lets researchers finally produce enough rasfonin ...

A switch between life and death

...d bantam, makes this link. Without bantam, tissues grow too slowly and remain smaller than normal. The amount of bantam produced by the cell directly depends on the amount of traffic on the Hippo signaling pathway, and higher levels of bantam prompt more cell division. "Bantam is an unusual type of RNA m...

How can identical twins be genetically different?

Synthetic molecule causes cancer cells to self-destruct

.... As a result, cancer cells escape destruction and grow into tumors. "We have identified a small, synthetic compound that directly activates procaspase-3 and induces apoptosis," said Paul J. Hergenrother, a professor of chemistry at the University of Illinois at Urbana-Champaign and corresponding author ...

UF scientists discover evolutionary origin of fins, limbs

.... We have genes that instruct our arms and legs to grow in the right places and point in the right directions. They also provide for the spaces between our fingers and toes and every other formative detail of our limbs. Evolutionarily speaking, the genetic instructions used to construct and position our...

Purdue creates new low-cost system to detect bacteria

...ng. Scientists in food-processing plants routinely grow cultures to test for dangerous pathogens. "The dairy industry, for example, grows bacteria on petri dishes to make sure products are safe, but industry is trying to develop technologies that will very quickly identify organisms," Robinson said. "Th...

Carnegie Mellon researchers discover new cell properties

...ing point that causes real problems." When people grow old, the walls of the cell nuclei exhibit similar problems to the HGPS nuclei, like losing their round shape and perkiness. "Our NIH collaborators have also found that the normal aged nuclei show the same structural changes as HGPS," Dahl said. ...

Brittle prions are more infectious

...uble clumps to create "seeds" that can continue to grow by causing aggregation of more proteins. In earlier studies, Weissman and his colleagues had discovered that the same prion can exist in different strains and have different infectious properties. These strains arise from different misfoldings of th...

Progress being made in exploring potential use of stem cells to treat heart disease

USC researchers investigate protein that protects tumors

...od vessels to grow. One key item for any cancer to grow is to include more blood vessels." The goal of a future anti-cancer therapy would be to block the protein, essentially knocking out one of the tumor cell's guardians. A similar approach was used to develop Herceptin, one of the first biological tre...
