For years, doctors and scientists have known very little about why patients can receive drugs successfully for months, or even years, before developing a drug resistance. Now researchers propose that there is a cellular as well as molecular cause to this phenomenon in colon cancer, with potential application to other similarly aggressive cancers as well.

Researchers have discovered that race plays no role in the amount and quality of the words mothers use with their children, or with the language skills their children later develop.

Many of the deadliest or most common cancers get the least amount of nonprofit research funding, reports a new study. 'Embarrassing' or stigmatized cancers, like lung and liver, are underfunded. Colon, endometrial, liver and bile duct, cervical, ovarian, pancreatic and lung cancers were all poorly funded compared to how common they are and how many deaths they cause, the study found. In contrast, breast cancer, leukemia, lymphoma and pediatric cancers were all well-funded, respective to their impact on society.

A psychologist asserts that those carrying the APOE4 gene score lower on IQ tests during childhood and adolescence. And the effect was stronger in girls than in boys. APOE4 carriers are up to three times more likely to develop late-onset Alzheimer's disease, which occurs in people 65 and older.

A new study used machine learning to find and comb through exercise-related tweets from across the United States, unpacking regional and gender differences in exercise types and intensity levels.

Researchers have found that a gene known as AEBP1 may play a central role in the development, severity and potential treatment of liver disease. One of the study's major findings is that AEBP1 regulates the expression of a network of at least nine genes related to fibrosis: AKR1B10, CCDC80, DPT, EFEMP1, ITGBL1, LAMC3, MOXD1, SPP1, and STMN2.

New research finds that low doses of radiation equivalent to three CT scans, which are considered safe, give cancer-capable cells a competitive advantage over normal cells.

The population of sub-Saharan Africa is set to double by 2050, yet a new study challenges a common misconception that this is caused solely by inadequate family planning.

Hallucinations are spooky and, fortunately, fairly rare. But, a new study suggests, the real question isn't so much why some people occasionally experience them. It's why all of us aren't hallucinating all the time.

Why does it take 200 million sperm to fertilize a single egg? Part of the reason is bombardment by the female immune system, which very few sperm survive. Researchers have discovered a molecular handshake between sperm and uterine cells that may help sperm evade this attack -- or may help the immune system target the weakest sperm.

Synthetic chemicals, including pesticides, medications and household cleaners, often end up in our waterways. Even in small amounts these substances can affect wildlife, plants and humans, and a number of them have shown resistance to normal water treatment methods. Researchers blazed the trail for a new field of sustainable chemistry by unveiling powerful, safe and inexpensive oxidation catalysts inspired by biological processes that break down even the most stubborn micropollutants.

Accurate and timely diagnosis of the tropic disease visceral leishmaniasis (VL) is one of the pillars for reducing VL deaths. Currently available serological tests for diagnosing VL vary widely in their performance and may, as a whole, be inadequate for VL diagnosis, researchers report.

A new animal study explores an alternative sirtuin-based therapy to block the development of obesity and cardiomyopathy under conditions of excess nutrition, when diet restriction and regular exercise are not feasible.

Aging men with low testosterone levels who take testosterone replacement therapy (TRT) are at a slightly greater risk of experiencing an ischemic stroke, transient ischemic attack (TIA), or myocardial infarction, especially during the first two years of use, reports a new study. The findings confirm concerns voiced by many health agencies about the potential risks associated with the treatment.
