New designer lipid-like peptide with lipid nanostructures for drug delivery systems

...designer lipid-like peptides is sufficient to form systems with excellent potential for various biotechnological applications such as the encapsulation of water-insoluble drugs and the delivery of biological active materials.” Currently, many anticancer drugs are difficult to deliver to patients due to ...

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

...vehicle employed autonomous navigation and mapping systems developed by Carnegie Mellon University’s Robotics Institute. During a two-week NASA-funded exploration led by Bill Stone of Stone Aerospace, the Deep Phreatic Thermal Explorer (DEPTHX) revealed that the geothermal sinkhole, or cenote, did not have ...

More recycling on the farm could reduce environmental problems

...y of Guelph, documents how semiclosed agricultural systems -- which he terms "regenerative" -- could enhance global sustainability of biological resources, curtail greenhouse gas emissions and groundwater contamination, and reduce farming's reliance on oil imports and water. A switch to regenerative agricul...

Ecology in an era of globalization

...icy interventions. In "The future of production systems in a globalized world," Elena Bennett (McGill University, Montreal, Canada) and Patricia Balvanera (Universidad Nacional Autónoma de Mexico, Morelia, Mexico) analyze ecosystem services, especially those providing food, fiber, and timber. They discus...

Amphibians in losing race with environmental change

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...nhibits the work of an enzyme that insects' immune systems use to defend themselves from attack. Although ...hy this research is so interesting. "The immune systems of all animals, even relatively simple ones like insects, are all very similar. "This is particul...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...trates how two of the most pervasive physiological systems -- G-protein coupled receptors and nitric oxide --...pressure. "We demonstrated that when one of the systems goes awry, so does the other," said Stamler, whose laboratory has made many fundamental discoveries ...

Alien plants attack using 'resource conservation' as weapon, researchers say

...of the study. "Typically people think low-resource systems aren't invasible. People think of the native plants as having a home-field advantage, because they evolved there." Smart plant growth Plants depend on sunlight, nutrients and water to survive, and a shortage of any one of these will restrict ...

Corals -- More complex than you?

...of such complex features as the nervous and immune systems of vertebrates. Around 10 or 12 per cent of the known coral genes are in fact shared uniquely with vertebrates ?these are genes that have been lost from all other animals so far examined. These include genes for the development of nerves, vision, ...

Targeting sugar on blood vessels may inhibit cancer growth

...the growth of tumors in these mice, but that other systems that rely on endothelial growth, such as the reproductive system and wound healing, remained robust." Studying mouse models with a genetic alteration in an important sugar-modifying enzyme (Ndst1), the researchers saw a marked decrease in the grow...

UQ research heralds vaccine technology breakthrough

... people with HIV or those who have weakened immune systems due to treatments such as chemotherapy. "Benefits of the vaccine will include a huge saving in health care costs," Professor Tindle said. "(It will also) relieve the burden of worry on thousands of parents who every year go through all kinds of a...

Gene mutation linked to cognition is found only in humans

...d memory, is expressed only in the central nervous systems of humans and that it originated less than 5 million years ago. The study, which also demonstrated the molecular mechanism that creates this novel protein, will be published online in Human Mutation, the official journal of the Human Genome Variation...

Dealing deadly cancers a knockout punch

...Reolysin has the ability to prime patients' immune systems against their particular cancer, leading to additional cancer cell killing. It is through this second "inflammatory" mechanism that researchers hope Reolysin will bring about long-term remissions of once-untreatable cancers. At the Fourth Internat...

...That premise will be tested in coming years as new systems become available." ...

Thymus transplants gives hope to babies with fatal immune disease

...nt to strengthen and maintain them as their immune systems rebuild," Markert said. "We have a remarkable team that takes care of these children in tightly controlled conditions during this important early period." Typically, children remain in the hospital for two to three months after transplantation as ...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...ts near "black smokers"—undersea hydrothermal vent systems that spew 350-degree Celsius water into the frigid deep-sea environment, and support sulphur-loving bacteria and bizarre worm and clam species—could smother and contaminate these communities, which some biologists argue may represent the origins of l...
