According to a new study published in Cell Metabolism, mice who spent their free time on a running wheel were better able to shrink tumors (a 50 percent reduction in tumor size) compared to their less active counterparts. Researchers found that the surge of adrenaline ( epinephrine) that comes with a high-intensity workout helped to move cancer-killing immune (NK) cells toward lung, liver, or skin tumors implanted into the mice.

While the research is hopeful for patients looking for inexpensive ways to manage their cancer, more needs to be learned about the effects of exercise on metastasis and longevity, as well as if the observations hold true in humans. Scientists also wants to explore the combined impact of anti-cancer treatments and ex ...

A possible vaccine for lung cancer! In a country known for cigars, lung cancer is one of the major killers in Cuba. So for the past 25 years, they’ve been developing Cimamax, which is now available freely to Cubans. According to a Phase II trial conducted in Cuba in 2008, lung cancer patients who received the vaccine lived an average of four to six months longer than those who didn’t. This led Japan and some European countries to trial the drug as well.

The drug itself is far from flawless and, by attacking a cell’s protein rather than the tumour directly, can have severe side effects, including – of all things - causing a higher risk of cancer. It might not be a "cure" in the traditional sense, but it's a way of managing the disease. What t ...

A new study from the California Institute of Technology (Caltech) estimates that our galaxy contains at least 100 billion planets. The team made their estimate while analysing planets orbiting a star called Kepler-32 - planets that are representative, they say, of the vast majority in the galaxy and thus serve as a perfect case study for understanding how most planets form.

As part of Donald Trump's cabinet pick, Myron Ebell, who is a director at the Competitive Enterprise Institute and a prominent climate change skeptic, will lead the Environmental Protection Agency's administration.

While Ebell has had no formal scientific education, and makes no claim to be a scientist, his view is that if public decisions are to be made according to scientific findings, than they should be discussed democratically by all people, not just scientists. Unfortunately, in the realms of science, public opinion doesn't matter much unless you're discussing the ethics of a scientific matter.

Appointing Ebell doesn't mean the environment is under threat, as suggested by the disenfranchised, New York Times. The discussion on global w ...

Chang’e-3 and the lunar rover Yutu (Jade Rabbit) landed on the lunar surface on December 14 at about 1:11 pm UTC. This is the first successful landing on the moon by any spacecraft in more than 30 years.

According to a new report published out of the UK, E-cigarettes are 95% less harmful to your health than normal cigarettes. When supported by a smoking cessation service, they help most smokers to quit tobacco altogether. They have also concluded that there is "no evidence" that they offer young people a gateway into smoking.

In fact, the review suggests that e-cigarettes may be contributing to falling smoking rates in the U.K., as 2.6 million adults are now thought to be using the product. They also found that almost all of these adults are ex-smokers, providing evidence that many people are not starting to use the devices after having never smoked in the first place, and instead are using them to either quit or cut down on tobacco.

Finally, the world is paying attention to the dangers of consuming trans-fatty acids in food.

The World Health Organization (WHO) has called all nations to rid foods of artificial trans-fats in the next five years. Artificial trans-fat is made by converting healthy unsaturated oils (those that are fluid at room temperature) into ones that are chemically more stable through a process known as hydrogenation (illustrated below). The food industry began using this deceptive technique in the 1950s to increase the shelf-life of perishable grocery items such as pastries, and fried foods sold at restaurants.


Numerous studies have linked these fats to an increase in cholesterol levels, which can lead to cardiovascular diseases. One of the reasons for ...

The medication is designed to be injected right after a traumatic experience. It targets Oprl1, a receptor that researchers believe is responsible for attaching fear to traumatic memories.

Post-traumatic stress disorder is caused by many things, such as surviving an accident or exposure to violence. There are genetic risk factors, but many people who acquire the disorder had no predisposition. Symptoms include debilitating flashbacks and hallucinations of the event, avoiding close relationships, angry or violent outbursts, and an inability to return to the location where the traumatic experience occurred, among many others.
