Triple negative breast cancer means that the three most common types of receptors known to fuel most breast cancer growth - estrogen, progesterone, and the HER-2/neu gene - are not present in the cancer tumor. Common treatments like hormone therapy and drugs that target estrogen, progesterone, and HER-2 are ineffective since the tumor cells lack the necessary receptors. A team of researchers from Garvan Institute of Medical Research, Australia, have found that the ...
Can tires be used to build houses? Sounds bizarre. But this in fact is a reality in highlands around the Colombian capital, where there are scattered small buildings made from the tires that litter the country's roads. Environmental activist Alexandra Posada, aged 35-years, is the woman behind the innovative project and seems to have found an ingenious solution to a tricky problem. Colombians throw out more than 5.3 million tires every year that pollute the environment. ... 
Myopia, or nearsightedness, is the most common refractive error of the eye, and it has become more prevalent in recent years. It is a vision condition in which close objects are seen clearly, but objects farther away appear blurred. Children's education is known to have a far greater impact on their sight than genetic factors. A century-old belief that high daylight levels in schools could prevent myopia may be true even today. The research on myopia has also revived an old ...

The study found that smaller plates may not encourage overweight teenage girls to reduce portion sizes because they may be less attentive to visual cues. Professor Lance Bauer from the University of Connecticut said, "It has been assumed that overweight or obese consumers are more likely ... 
The human sex ratio is the ratio of males to females in a population. Global sex ratio records at birth consistently suggest that boys naturally outnumber girls at birth. Researchers at Harvard University and Oxford University analyzed the largest dataset from United States to explain the human sex ratio, which has been poorly understood until now. Their findings suggest that boys and girls are equal in number at conception, but more female fetuses die during pregnancy, leading ...
