Why you should drink water regularly

After all, water makes up more than two-thirds of the weight of the human body.
Without water, humans would die in a few days.
“Healthy people meet their fluid needs by drinking when thirsty and drinking with meals.
“If you just drink a glass of orange juice, you get much less fiber,” the web site said.
The web site explained: “When you become too hot, your blood vessels dilate and you start sweating.
“If children drank more water rather than getting extra calories from soda, that’s good…but there is no evidence that drinking water before meals reduces appetite during a meal.” In a way, water is not fattening, as some people claim.
Drink little by little throughout the day.
By the time you feel thirsty, you’re probably two glasses below your normal water needs.
Drinking alcohol is much worse, because it actually dehydrates you by making you urinate a lot.
“Unlike the energy crisis,” commented Klaus Toepfer, former executive director of the United Nations Environment Program, “the water crisis is life threatening.

Research unravels mysteries of mouthparts of butterflies

A study by Matthew Lehnert, Ph.D., assistant professor of biological sciences at Kent State Stark, shows that the method in which flies and butterflies ingest liquids into their own bodies for nourishment may be used as a model for delivering disease-fighting drugs to the human body.
Drug delivery systems are engineered technologies for the targeted delivery and/or controlled release of therapeutic agents.
This study also found that there is a limiting pore size from which each individual can feed — butterflies and flies with smaller mouthpart channels will be able to feed on liquids from smaller pores, which might have an advantage for the insects and more broadly for the ecosystem in case of a drought.
Lehnert, three of his Kent State Stark undergraduate student assistants and four other researchers found that flies, butterflies and moths (20 percent of all animals) use capillary action, or the movement of liquids seamlessly from one place to another, as the guiding principle when feeding on liquid films — their primary source of food.
An insect’s proboscis, a body part that allows them to drink liquids, acts like a highly-sophisticated sponge and straw that uses capillary action to send nectar or other liquids to the insect’s diges tive system.
In order to feed on nectar and other liquid films, natural selection has favored the evolution of specialized mouthparts in fluid-feeding insects.
In butterflies and flies, the mouthparts consist of a proboscis adapted for using capillary action to pull thin films of fluid from surfaces for subsequent feeding.
By copying this natural method, scientists say the mouthparts of flies and butterflies can serve as models for developing new devices for improved drug delivery systems.
