American scientists have predicted that over 1 billion to become obese by 2030. Obesity has become a worldwide problem. 

A new study published in the International Journal of ‘Obesity’ has established that almost one-third of the population of world is overweight. The study is conducted in 106 countries worldwide. 

A new study conducted by an international group, led by researchers at Glasgow University, revealed that smoking leads to hundreds of thousands more deaths every year than thought earlier.

The researchers group discovered that puffing raises the chances of dying from cancers of the colon, rectum and prostate and also from lymphatic leukaemia.

An international group of researchers revealed that electromagnetic fields emitted by cellular phones may be ‘risky’ for children.

The researchers have warned parents to ensure and see that children are kept away from the mobile phones.

In this way, the study favors limited access to mobile phones for children.

A new study carried out by Lauren Brown, a researcher with University of Alberta’s School of Public Health, Canada has revealed that those who take certain medications in order to treat their depressive moods (depression) are at higher risk of having ‘Type 2 diabetes.’

A new U.S. study has discovered that there is a relation between certain genetic variations and brain tissue mutations, and people with schizophrenia.

Before this time, these slight and delicate brain tissue mutations have not been able to be revealed, but because of new improvements in gene scanning technology, they seem to be associated with the disease, and they may clarify how the disease is caused.

If old women want to remain fit, they have to eat plenty of protein-rich food, a new study says.

The study revealed that older women must consume plenty of protein as their bodies find it difficult to replace the lost muscles, as compared to the aged men.

Scientists at the University of Tokyo have got success in making kidneys and pancreases in mice that had been reprogrammed to grow without such organs, by putting in embryonic stem cells from strong mice into fertilised eggs.

The result of the study at the university’s Institute of Medical Science has raised expectations for developing human organs from stem cells.

The UK researchers have identified a gene variant linked to higher gout risk.

The scientists at the MRC Human Genetics Unit in Edinburgh have noticed a variation in the SLC2A gene that makes it more difficult for the body to take away uric acid from the blood and therefore raising the risk of having ‘gout.’

Researchers of Semmelweis University in Budapest have conducted a study and discovered that loud snoring can give rise to heart attacks and strokes.

After surveying about 12, 463 Hungarians, the researchers discovered that loud snorers are more likely to have 34 percent higher risk of heart attack, 67 percent greater chance of suffering a stroke and 40 percent greater odds of having hypertension as compared to peers who do not snore.

According to the scientists of Dundee University, diabetes can be controlled by drinking black tea.

The constituents of black act as an insulin substitute to combat type 2 diabetes, the most common form of the disease.

Diabetes develops when insulin inside the body start falling. In Scotland, more than 190,000 people have diabetes.

Dr. Anil Sood, an Indian-origin researcher and a Professor of Gynecologic Oncology and Cancer Biology in the M. D. Anderson Cancer Center, has developed a protein interleukin-8(IL-8) that helps in the treatment of ovarian cancer.

Sood has found out a short interfering RNA (siRNA) product that slashes IL-8 expression, and decreases the size of the tumor by attacking blood supply.

Sood said, “The protein IL-8 is a potential therapeutic target in ovarian cancer.”

The study conducted by the researchers of Georgia University has revealed that low-intensity workouts such as a leisurely stroll can reduce body tiredness (fatigue) by 65 percent, and could boost up body energy levels up to 20 percent.

Researchers disclosed this finding through an experiment involving 36 healthy young individuals who did not exercise regularly and remain always fatigued.

A new study has disclosed that intake of Vitamin E in high doses can double-up the risk of lung cancer.

The study researchers found that people who consumed Vitamin E in increased quantity had a greater risk of having lung cancer.

The laboratory examinations made by US researchers on rats have found that a concentrated extract of freeze-dried broccoli sprouts reduces the growth of bladder tumors by more than half.

Dr. Yuesheng Zhang of Roswell Park Cancer Institute in Buffalo, N.Y. stated that the new outcome supports human epidemiologic studies, which advise eating cruciferous vegetables such as broccoli is linked with reduced risk for bladder cancer.

A new study has suggested that ‘Viagra’ may be good for boosting a man’s sex life, but it may also damage sperm and fertility rate.

The British study discovered that young men who take Viagra could be destroying their abilities to have families.

Dr. David Glenn, a consultant gynecologist at Queen's University Belfast, carried out two experimentations on Viagra, and the results will be issued in the journal ‘Fertility and Sterility’.

A new study conducted by the researchers at the University of Michigan Health System suggests that obese children are more prone to breathing related problems during surgery, as compared to their normal-weight counterparts.

The study results are published in the journal ‘Anesthesiology.’

Researchers have reported that a gel, which makes use of an anti-HIV drug ‘Tenofovir’ to defend women from the AIDS virus, is harmless as well as tolerable to women.

The study by scientists at the University of Alabama at Birmingham (UAB) and the University of Pittsburgh to examine the gel’s safety involved 200 sexually active HIV-negative women aged between 19 to 50, out of which 64% were married.

A new study says that new generation anti-depressant drugs including Seroxat and Prozac have small medicinal effect on the majority of patients.

The world’s well-known anti-depressant ‘Prozac’, which is taken by over 40 million people throughout the world, does not actually help improve the patient’s mental condition.

A recent study has found that there is a relation between
mobile phones and cancer.

In reality, the mobile phone increases the risk of cancer to
the salivary glands, the study says,

Researchers viewed 500 Israelis who have had salivary gland
cancer and compared their cell phone usage with 1,300 healthy controls.

They found that the people who use cell phones on one side
of the face for a long time about 50% daily are detected with developing salivary
gland tumors.

A study carried out by international group of researchers called, India a hotspot for emerging infectious diseases (EIDs) like HIV/AIDS and SARS.

The study findings were released in the journal ‘Nature.’

In medical terms, the word 'emerging diseases' is described as newly identified pathogens, or old ones traveling to novel areas.

The scientists said that the diseases, which travel from animals to humans (zoonoses) like bird flu, are of special worry, and they have grown throughout the world.

European scientists have carried out an analysis and discovered that people who depend on vitamin tabs, in place of eating a balanced diet of fresh fruits and vegetables, are doing more harm than good.

The researchers said that three supplements including Vitamin A, Vitamin E and beta carotene can raise death rates among those taking them.

But, Vitamin C and selenium tablets have no effect as such.

It has been already cleared that smoking or heavy alcohol intake give rise to cancer.

But, a novel study has discovered that harmful chemicals from smoking and alcohol can damage sperm, which then pass altered genes onto babies.
