Lateral thinking produces first map of gene transmission

...enes are transferred between organisms that aren't directly related. The map has traced the paths of lateral gene transfer, from the bacteria that donated the genes to the ones that received them. Their results clearly show genetic modification of organisms by lateral transfer is a widespread natural phen...

Some good news for the world's poor

..., the same level of output at a lower cost), which directly improves farmers' income. Second, the diffusion of modern varieties results in lower food prices, as demonstrated in several studies. This is critical given that the poorest people spend a large share of their income on food. Third, the productivit...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

... is expensive and hard to obtain, had to be pumped directly into the brains of Parkinson's patients for it to work, as it is unable to cross the blood-brain barrier. In an effort to develop a less invasive strategy to effectively deliver the drug to the brain, Svendsen's team implanted the GDNF secreting cel...

Johns Hopkins flu expert calls for mandatory vaccination of health care workers

...t patients from accidentally contracting the virus directly from an infected medical staff worker or indirectly from other patients or visitors via medical staff. Previous research from Hopkins showed that annual flu shots have been almost 88 percent effective at reducing the risk of flu infection and that...

Group proves it's possible to grow new lung alveoli by growing new blood vessels

... adenovirus and administered it through an aerosol directly into the lungs. In effect, the virus carried the protein to the heart of millions of lung cells. Once inside the cells, the growth factor proteins went to work doing the job they were programmed to do. The results were striking: In microscopic image...

Wild birds help to create human flu vaccine

...y threatened or endangered are also being impacted directly by the H5N1 strain of influenza virus. Focusing resources on the hubs and activities where humans, livestock, and wildlife come into close contact is the best hope for successfully preventing the spread of avian flu and protecting both people and an...

Asleep in the deep: Model helps assess ocean-injection strategy for combating greenhouse effect

...y resulted in 37 human deaths. The deaths were not directly caused by the explosions, but resulted from carbon dioxide asphyxiation. "Carbon dioxide is denser than air, so it settled down and flowed along the river valley, choking people and animals to death." The challenge in designing CO2 injection strate...

ASU researchers 'wire' DNA to identify mutations

...demonstrate for the first time, the possibility of directly identifying these mutations, or single nucleotide ...for Solid State Electronics Research. "We can now directly read the biological information in a single DNA molecule." Measurement of DNA conductivity first r...

Targeted drug delivery achieved with nanoparticle-aptamer bioconjugates

...ssible for their cytotoxic payload to get released directly inside the cancer cells. The combination of targeted delivery and controlled release of drugs at the site of cancer will likely result in "smart therapeutics" that are more effective, yet safer than what is available today. As the initial step, rese...

Researchers use 'trickery' to create immune response against melanoma

The combination of targeted delivery and controlled release of drugs at the site of cancer will likely result in "smart therapeutics" that are more effective, yet safer than what is available today. As the initial step, rese...

Stress substantially slows human body's ability to heal

...emoved from each blister and another device placed directly over each small wound, forming a protective bubble, from which researchers could extract fluids that normally fill such blisters. The husbands and wives also completed questionnaires intended to gauge their level of stress at the beginning of the e...

Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

...ests and animal husbandry," says Weldeab. "Drought directly affects them; they run out of food for people and animals." ...

Scientists directly view immune cells interacting to avert autoimmunity

...dye to mark different types of cells so they could directly observe the interactions of the key cell types involved in initiating autoimmune attacks and the control of their actions by therapeutic regulatory T cells. The "nonobese diabetic" (nob) mouse model used in the research is considered the "prototypic...

Hot-spring bacteria flip a metabolic switch

...ic acids, but N2 gas from the atmosphere cannot be directly used for this purpose; it must first be reduced or fixed into larger, carbon-containing compounds. N2 fixation is a problem for photosynthetic cells, since the oxygen produced during photosynthesis inhibits the nitrogenase complex--the enzyme factory...

3D ultrasound device poised to advance minimally invasive surgery

... with a tiny video camera that surgeons can insert directly into the abdomen or chest through small incisions. "With our scanner, doctors could see the target lesion or a portion of an organ in a real-time three-dimensional scan," Smith said. "They would have the option of viewing the tissue in three perpend...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

...day fish called a transposon to transport the gene directly into the DNA of the mice. Nonviral therapy is thought to be safer, Fletcher said. Transposons have the natural ability to bounce to different positions in DNA, allowing them to chauffeur genes into the cell. The transposon UF researchers used is one...

Study ties 'new' cell-death mechanism to developmental and degenerative brain disorders

..."This is the first time neurodegeneration has been directly linked to potassium channel mutations." In the Nature Genetics article, the researchers describe their analysis of two ataxia-causing mutations of the KCNC3 gene ?one present in a Filipino family and one in a French family. Although both mutations ...

HIV/AIDS rates in Tijuana, Mexico increasing at alarming rate

...etin of the New York Academy of Medicine. Located directly south of San Diego California, Tijuana is a city of 1.2 million people located amidst the busiest land border crossing in the world. Data in this study suggest that Tijuana's HIV infection rate may be close to three times higher than Mexico's nation...

Learning and memory stimulated by gut hormone
