Dysentery uses 'sword and shield' to cause infection

... This allows the needles to inject proteins, while protecting the bacteria from being destroyed by the immune system. Dr Tang adds: "This discovery greatly expands our understanding of how bacteria are sometimes able to evolve although it is unlikely to result in new treatments or vaccines for dysentery. In th...

Research advances quest for HIV-1 vaccine

...y. Vaccination has been a successful strategy for protecting humans from many potentially harmful viruses. However, designing a suitable vaccine for HIV-1 has been a highly challenging and thus far unsuccessful endeavor. HIV-1 is enormously variable and it has been difficult to isolate antibodies that will rec...

Research on Worms Yields Clues on Aging

...trated that anticonvulsants did not extend life by protecting theworms from pathogenic bacteria in their environment.Ethosuximide and trimethadione did, however, significantly delayage-related declines in neuro-muscular activity. Treated wormscontinued to display the youthful traits of fast body movement and fa...

Iron Deficiency Sparks Dramatic Changes In Gene Expression

...erating energy, copying thecell's genetic code and protecting the cell from free radicals andaging, said Thiele."We discovered that iron deprivation actually reprograms the metabolismof the entire cell," said Thiele. "Literally hundreds of proteinsrequire iron to carry out their proper function, so without this...

Enzyme shown to help protect genomic stability

...hat an enzyme known as Ubp10 plays a vital role in protecting the telomeric regions of the genome from potential destabilizing molecular events. The enzyme helps to keep the genome structurally closed, unavailable for transcription and possibly protected from dangerous genetic recombinations with other regions ...

Experiments provide proof of how traveling in groups protects insects

... small animals congregate periodically as a way of protecting themselves from predators such as birds and rodents. Now, a trio of insect experts has developed what they believe is strong new evidence that the latter theory is correct. By gluing radio transmitters -- each weighing less than half a gram -- to th...

International HapMap consortium expands mapping effort

...ions that contribute to good health, such as those protecting against infectious diseases or promoting longevity. "We are excited by the opportunity to apply our technology to all publicly available SNPs. This effort is so important that Perlegen is willing to contribute some of its own resources to make this ...

Scientists discuss improved biopesticides for locust control in West Africa

...articipated in this project by developing means of protecting short-lived fungal spores from ultraviolet light, a key facet of biopesticide research. OIRED (http://www.oired.vt.edu/) at Virginia Tech manages two large global projects funded by USAID. ...

Biodiversity hotspots identify conservation priorities

... by concentrating on the hotspots, we are not only protecting species, but deep lineages of evolutionary history," Mittermeier said. "These areas capture the uniqueness of life on Earth." The hotspots concept was pioneered in 1988 by British ecologist Norman Myers, who recognized that hotspot ecosystems (most ...

Some Brain Cells 'Change Channels' To Fine-tune The Message

...ef is that the cells might be doing more than just protecting themselves by keeping calcium out." In some cases, protection might be enough of a goal. In people with Lou Gehrig's disease, or amyotrophic lateral sclerosis (ALS), some muscle-controlling nerve cells die because too much of the brain chemical glut...

UN votes to ban human cloning

...ed because it believes therapeutic cloning aims at protecting human life and is, therefore, inconsistent with the Declaration. It will continue to control therapeutic cloning strictly. The United States, which voted for the Declaration, supports a total ban on human cloning. It added, however, it does not prohi...

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years

...ratulate countries for their successful efforts in protecting children from measles," said Dr LEE Jong-wook, WHO Director-General. "I am certain that with increased commitment from governments and further support from the international community, even more can be accomplished." Measles is an important cause of...

Scripps scientists find potential for catastrophic shifts in Pacific ecosystems

... of understanding ocean processes and managing and protecting marine resources, a group of researchers at Scripps Institution of Oceanography at the University of California, San Diego, has developed a groundbreaking analysis of the North Pacific Ocean and how dramatic changes can unfold across its waters. The...

A New Species of Monkey is Discovered in Tanzania: The First in Africa for More Than 20 Years

...uld serve as a living symbol that there is hope in protecting not only wild places like Tanzania’s Southern Highlands, but the wonder and mystery they contain." Meanwhile, WCS continues its conservation work in the Southern Highlands, while CI and independently funded researchers continue to support conservati...

Evolution of taste receptor may have shaped human sensitivity to toxic compounds

...as played in forming our present sensitivities and protecting us from harmful natural chemicals. The research team analyzed the nucleotide sequence of a human gene encoding a bitter-taste receptor that mediates recognition of a class of naturally ubiquitous, but toxic, cyanide-releasing compounds. By analyzing ...

Genomic sequences processed in minutes, rather than weeks

...s, finding safer ways to clean the environment and protecting the country against biological threats. ScalaBLAST is a sophisticated "sequence alignment tool" that can divide the work of analyzing biological data into manageable fragments so large data sets can run on many processors simultaneously. The technol...

Millennium Ecosystem Assessment: Many of 2 billion dryland dwellers at risk as land degrades

... Proper land use management policies are needed to protecting existing vegetative cover from overgrazing, over-exploitation, trampling and unsustainable irrigation practices. Finally, creating viable livelihood alternatives for drylands populations should become part of national strategies to combat desertific...
