Poplar trees redirect resources in response to simulated attack

...d by building up tolerance, for example by putting aside more carbon into storage so it will be available to help the plant spring back to life once the attack has passed. Using the techniques developed at Brookhaven, we now have a way to find out." To simulate an insect attack, the scientists painted a s...

Tiny scaffolding allows stem cells to become working fat cells

...ther lose existing fat cells or grow new ones. And aside from the implications for dieting and obesity, a person's population of fat cells has other vital roles. Fat cells extract lipids, or fatty acids, from the bloodstream. They also become a huge reservoir for glucose as well, and play a role in insuli...

The genetic origins of corn on the cob

...new species. Its "peculiarly shaped ear" was "laid aside as a curiosity" and the specimen was designated Zea ramosa (from the Latin ramosus, "having many branches"). Due to the alteration of a single gene, later named ramosa1, both the ear and the tassel of the plant were more highly branched than usual, l...

Penicillin, amoxicillin: Step aside for strep throat treatment

... stalwarts like penicillin and amoxicillin to step aside when it comes to the treatment of strep throat. The most common medications used to treat the strep germ, the bug that causes millions of sore throats in U.S. children every year, simply aren't doing the job and aren't as effective as newer antibiot...

Preclinical study of a new brain tumor therapy

...treatments for GBM. There are few existing options aside from chemotherapy and surgery to remove the tumor, and it is rare that these treatments stop the cancer from recurring. Given the prevalence of EGFR in cells of other cancer types (such as breast cancer and lung cancer), the approach pioneered in thi...

Study finds drug may cut down involuntary movements

...e 1950s to treat psychosis, but was quickly pushed aside by more effective medications. But doctors in the United Kingdom found it to be effective to treat the excessive involuntary movements of Huntington's, and it is approved for use in several nations. In the United States, tetrabenazine is designated a...

New lab technique churns out fungus' potential cancer fighter

...Until now, no method existed to generate rasfonin, aside from growing more fungus--a time-consuming and terribly inefficient method.Boeckman, the Marshall D. Gates, Jr. Professor of Chemistry at the University of Rochester, has now revealed a process that produces 67 times more rasfonin than any previous m...

Deep-water discovery

...t--it's a unique ecosystem. I find myself putting aside other work to pursue this further as I see this as a once-in-a-lifetime opportunity." Researchers have suspected since the 1970s that deep reefs lay undiscovered between Miami and Bimini because pieces of reef-building corals had been brought up usi...

When the going gets tough, slime molds start synthesizing

...is is a wonderful example of where egos get pushed aside about who did what and instead, as a scientific community, groups come together to address a fundamental question in biology. In the process, we collectively discovered an efficient chemical factory in Dicytostelium cells that informs us about how to...

'Sticky' mice lead to discovery of new cause of neurodegenerative disease

...tRNA synthetase gene. And there it was." To set aside any doubts they might have had about the role of the tRNA synthetase gene, Ackerman and her colleagues showed that they could correct the pathology in the sticky mouse mutants by using genetic techniques to insert a normal version of the tRNA synt...

Funding and bureaucracy, not access to journals, are chief obstacles to scientific productivity

... by the Publishing Research Consortium found that aside from lack of resources, a 'stop-go' funding culture prohibits scientists from initiating new ideas, choosing research projects that contrast with funders' priorities, and recruiting and retaining qualified staff. Conversely, the study found that ...

Salk scientists get to the root of plant cell fate

... and flowers. "We want to know how a plant can set aside a root and a shoot pole during embryogenesis and keep these functions separate," Long says. The researchers found that the TOPLESS gene encodes a protein (TOPLESS) that is a transcriptional co-repressor. In plants and animals, co-repressors regulate...

Nice guys do finish first in lizards' evolutionary race

...ocused on why the blue throats are willing to cast aside their own opportunities to procreate for the benefit of a friend. "Why not abandon them and become loners ?why not go it alone?" McAdam said. "The blue throats can set up new territories and be successful. That's the evolutionary puzzle that we need...

Mapping the mouse genome

...ne of the most detailed genetic maps now available aside from that for humans. To create this map, they used two groups of mice: one consisting of outbred, heterogeneous stock (HS) and the other of recombinant inbred lines (RI). Using the single nucleotide polymorphism (SNP) data that resulted from phys...

Cancer tip -- Nanoparticles can damage DNA, increase cancer risk

... what makes matters worse is the fact that so far, aside from preventing their release, there are no known ways to prevent the harmful effects of environmental nanoparticles. "It is important to know whether the nanoparticles are entering the cell and causing DNA damage directly or if they are acting on...

Synthetic peptide targets latent papilloma virus infections

...evelopers to design a molecule that can nudge Brd4 aside so as to bind and block the action of E2. Botchan, who has studied DNA replication in viruses for 30 years to understand similar processes in higher organisms, says that such a drug might work against all strains of HPV because the E2 tethering pro...
