In experiments, the monkeys create more cells that should know how to attack HIV, but more research will be needed to see if this means their immune systems can actually repel the virus.
Because they believe the levels of bisphenol A (BPA) that migrate from the can linings are a health hazard as they equal the amount of BPA given to animals in experiments where adverse health effects were found.

Scientists use at least 20 million rodents a year in experiments in the U.S., to test foods, drugs and chemicals and to unearth basic truths about the causation of disease and the functioning of the human immune system.
In experiments on dogs they have found that by pumping liters of ice-cold salt water into their arteries and cooling them down to 59 degrees they can preserve vital organs up to three hours after the heart stops.
In experiments performed at Los Alamos National Laboratory, when humans were asked to perform object recognition tasks, the experiments were kept under an hour so as not to get to the point where the subjects could no longer focus on the task.

Scientists from the Centre for Heavy Ion Research in Germany, led by Professor Sigurd Hofmann, discovered copernicium in fusion experiments in 1996.
In groundbreaking experiments in the late 1990s, Emory professor Frans de Waal showed that capuchins will refuse to "work" if they feel they are getting an unequal share of the rewards.
It is therefore something of a mystery why researchers concerned about mouse contamination did not engage in a literature search to establish whether the primers used in their experiments were in fact specific to XMRV sequences which are unique to the virus.
FORBES: Big Study Linking Chronic Fatigue To Virus May Be Fatally Flawed
As the Nobel-winning economist Vernon Smith (now of Chapman University) and colleagues found in laboratory experiments, markets in goods for consumption promote cooperation, but markets in assets for speculation and resale produce bubbles and crashes.
Although the ultimate outcomes of the low-fat and low-carbohydrate diets in the experiments were the same, in that people lost similar amounts of weight over the course of a whole year, this is unlikely to deter the hordes of Atkins aficionados who swear by the diet.
In lab experiments, the researchers exploited a loophole in the way Origin handles links to games users have downloaded and installed to make it run code that compromised a target machine.
Men tended to make riskier choices in these experiments, which led researchers to conclude the women in general have less appetite for risk.
