Scientists find genes involved in the battle between Hessian flies and wheat

...y larvae that survive eventually evolve methods to overcome plant defenses. Purdue University and USDA-Agriculture Research Service scientists trying to thwart the insect have identified Hessian fly genes that nullify toxins that wheat produces to protect itself from the munching larvae. The researchers repo...

Gut research yields new anti-cancer approach

...n), he said. High-dose PPARgamma inhibitors may overcome the limits of current treatment because the profile of molecules likely to be pumped out by drug efflux proteins is known, and at least one of the PPARgamma inhibitors does not match it. In addition, PPARgamma inhibitors do not bind to the standard t...

Students invent protective pouch to enhance cell therapy

...ealthy body functions. Arepally and Bulte have overcome some of these hurdles by working with semi-permeable alginate microcapsules ?tiny spheres that surround the injected cells and protect them from the body’s immune system. At the same time, the spheres allow beneficial proteins to flow out and oxygen ...

The sound of proteins

...lodies more pleasing on the ear, they had first to overcome a few problems ?how to incorporate rhythm, and how to cram the 20 standard amino acids (the building blocks of proteins) into just 13 notes. The duo focus on codons ?sets of three adjacent bases that code for particular amino acids. They decided...

More recycling on the farm could reduce environmental problems

...ing suggesting, however, that price premiums could overcome this disadvantage, and points out that social benefits could be expected. Pearson argues that existing funding programs for farmers could be modified to encourage more regenerative agriculture, and suggests that philanthropists and professional bodie...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

...ls, while irregular, lack distinctive features. To overcome this challenge, DEPTHX had to navigate by recognizing a more global response from all of its sensors. Wettergreen said demonstrating that SLAM could work in such a featureless environment suggests that it will have applications in environments wit...

Skimmed milk -- Straight from the cow

...d fats,’ according to Komorowski. This may also overcome the problem of waste. ‘If you can genetically produce milk without fat then that may turn out to be a very good solution to what might later be a big disposal issue,’ says Komorowski. Producing skimmed and semi-skimmed milk means there is a lot of fa...

Putting feelings into words produces therapeutic effects in the brain

...erman said. “People don’t do this to intentionally overcome their negative feelings; it just seems to have that effect. Popular psychology says when you’re feeling down, just pick yourself up, but the world doesn’t work that way. If you know you’re trying to pick yourself up, it usually doesn’t work — self-de...

Researchers demonstrate way to control tree height

...ustries, experts say, if regulatory hurdles can be overcome – a big “if.” The findings were recently published in the journal Landscape Plant News. “From a science perspective, this is a very interesting accomplishment and there’s no doubt it could be made to work,” said Steven Strauss, a professor of...

Exploring the dark matter of the genome

... in sequencing the Drosophila heterochromatin have overcome previous technical limitations, extended understanding of heterochromatin's organization and constitution, and led to new insight into how it helps cells and organisms survive. The latest results from the DHGP are reported in a pair of papers in the ...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...ses. The approach represents a potential way to overcome hurdles in delivering cargo to the interiors of cells, where they could be used as an alterative technology for gene therapy, said Rashid Bashir, a researcher at Purdue's Birck Nanotechnology Center. The researchers attached nanoparticles to the o...

Now, self-healing materials can mimic human skin, healing again and again

...ter seven healing cycles. This limitation might be overcome by implementing a new microvascular design based on dual networks, the researchers suggest. The improved design would allow new healing chemistries – such as two-part epoxies – to be exploited, which could ultimately lead to unlimited healing capabil...

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

... The result is that a person seriously wishing to overcome obesity could take this compound orally in order to curb his appetite, thus leading to natural weight loss. In experiments with mice, it was shown that a single oral administration of BL-3020 led to reduced consumption over a period of 24 hours. Over...

Crammed with charged DNA, pressure rises inside virus

... “The virus’ motor has to do mechanical work to overcome two factors that create resistance,” said Douglas Smith, an assistant professor of physics at UCSD who headed the team that published the discovery this week in the early on-line edition of Proceedings of the National Academy of Sciences. “First, th...

Genomic Analysis Uncovers New Targets for HIV Vaccine

...these genes, and help the body's own immune system overcome an infection. One of the genes looks particularly attractive as a vaccine target. The study, published early online by the journal Science July 19, was directed by David Goldstein,Ph.D., at Duke University and is the first large cooperative study wi...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...ding. Scientists can quantify the energy needed to overcome this resistance. The Carnegie Mellon team found that FP-23 reduces the energy required to penetrate an artificial cell membrane by up to 13 fold, depending on the thickness of that membrane. “Reducing this energy should help explain in part how HIV ...
