Parasitic worms may help fuel AIDS epidemic: study

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

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?

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.
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!

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.
Africa and Asia face severe crop losses from climate change within 20 years

Agriculture is the human enterprise most vulnerable to changes in climate. According to a new study : many of the world's poorest regions could face severe crop losses in the next two decades because of climate change,

One of the world's best health care bargains just got better. A new study conducted in Zanzibar, Tanzania, shows that three drugs can safely and simultaneously treat three of the world's most burdensome parasites. The medicines are cheap--pennies per person--but delivering them to patients isn't. Until now, no one was sure if health workers could safely economize by giving all three at once.
Passing the Buck on Environmental Damage

Humans inflicted $47 trillion worth of damage to the environment from 1961 to 2000, according to a new study, and poor nations are disproportionately footing the bill.
