Parasitic worms may help fuel AIDS epidemic: study
kavin submitted, created time 4 months 5 days (www.reuters.com)
People infected with parasitic worms may be much more susceptible to the AIDS virus, according to a study published on Tuesday that may help explain why HIV has hit sub-Saharan Africa particularly hard.
The study involving monkeys demonstrated how a type of parasitic worm that causes schistosomiasis, which affects 200 million people globally, may make HIV infection more likely.
Much lower amounts of the AIDS virus--seventeen times lower--were needed to cause infection in monkeys who had the parasitic worms than in the parasite-free monkeys, the researchers said 
New insight into SIDS--can seratonin alone cause death?

Mouse model suggests serotonin might play a role in crib death. This research team created mice with unusually high levels of seratonin receptor 1a (Htr1a), a receptor that binds to seratonin, decreasing the free levels of the neurotransmitter. (In other words, a mouse with high levels of receptor 1a will seem like a mouse with low levels of seratonin, even though its ability to produce seratonin is unimpaired.) They found that the mice periodically went into "crisis" states during which their heart rates and body temperatures plummeted
Genomic medicine sector "needs government backing"

Government support, strong leadership within institutions and the protection of "genomic sovereignty" are vital to the burgeoning genomic medicine sector in developing countries, say researchers.
Some developing countries are starting to use genomic science, aiming both for public health benefits and to produce knowledge to stimulate their economies. They often do this by setting up large-scale genotyping projects to assess susceptibility to disease
Food crisis calls for renewed vigor in agricultural research
Darkfrog submitted, created time 7 months 13 hours (www.nature.com)
Agricultural research may not sound flashy--it includes everything from high-yield crop varieties to pest and weed control--but experts claim that a lack of it is the underlying cause of our current food shortages in the developing world, and that it is likely to be the cause of future shortages if the problem is not corrected.
While there is a focus on agricultural research in the developing world, this is limited to four countries: China, Brazil, South Africa and India. At the same time, there is less and less transfer of technology and information from first-world countries like the U

Farmers' yields in the developing world are often limited by unreliable rains. Improving their harvests will require plant breeders, agronomists and geneticists to pull together — but can these experts work out their differences?

World Water Day is coming. The theme of 2008 is SANITATION. More than a billion people do not have access to safe drinking water and two billion have inadequate sanitation.
New drug holds promise for parasitic worm disease

Zambia sees nearly four million cases of malaria diagnosed each year, and some 50,000 deaths, mostly among children. Two years ago, its Ministry of Health embarked on an ambitious plan to cut the incidence of malaria by 75%. They developed a efficient strategy which may spread in their neighbor countries successfully.
Disease monitors "looking in the wrong places"

The world's health watchdogs are looking in the wrong places for the next dangerous epidemics, according to an analysis of global trends in emerging disease outbreaks over the past few decades. Health leaders need global strategy for spotting disease threats.
Engineered crop plants: Trap or treasure?
Darkfrog submitted, created time 9 months 2 weeks (www.nytimes.com)
This article discusses the proliferation of genetically engineered crop plants in the international agricultural market, particularly in developing countries. The concern is that poor farmers will become beholden to the companies that own the patents on these particular strains, but I think the whole matter is fear-hyped. Genetically engineered crops tend to be hardier, more cost-effective and require less pesticide. That's a good thing all around.
Criminals hawk fake malaria drugs
Sue Wu submitted, created time 9 months 2 weeks (www.nature.com)
Malaria is still a major problem in developing countries. Fortunately, there are many brand-name and generic drugs that can ease symptoms and save lives. Unfortunately, these drugs aren't always easy to get to the people who need them. Also unfortunately, there are people willing to take advantage of and money from the sick and their relatives.
Still, drug enforcement agents managed to track down some of the counterfeiters. You will never guess how they did it!
WHO reports that anti-malaria efforts are working

A combination of nets and spraying has been connected to significantly reduced malaria deaths in developing countries. I thought everyone could use some good news.
Kraft develops food products meant to kill intestinal worms
Darkfrog submitted, created time 9 months 3 weeks (www.nytimes.com)
Kraft Foods, famous for revolting plastic cheese and inoffensive food bars, plans to incorporate compounds meant to kill roundworms and other troublesome parasites into food products that have yet to be named.
This article is engaging and easy to get into, almost definitely written for the non-scientist. Still the story of how the antiparasitics were discovered is brief and interesting.
Kraft would hardly be the first company to tailor its products to each target country. The most famous example is probably Coca-Cola's country-by-country formulas.
Genetic discovery can boost the provitamin A content of Africa's maize

A new discovery could change health disorders caused by lack of provitamin A. Using genetic and statistical tools, researchers have identified a set of genetic variants in maize that accounts for levels of vitamin A precursors among varieties.
The evolution of a killer---tuberculosis
jane2007 submitted, created time 1 year 2 days (www.nature.com)
The work suggests that if better tuberculosis surveillance programmes had been in place during the past decade in developing countries, antibiotic treatments could have been better tailored to patients, and the emergence of extensively drug-resistant strains of tuberculosis (XDR-TB) could have been delayed.
This article narrates the history and the current status of the killer--- tuberculosis. I think the difficulty or the mission is in the text too.
