When a person dies from cancer, the culprit isn't usually the original tumor - it's metastasis, the spread of cancer cells throughout the body. Now, researchers have managed to package a drug in nanoparticles (a microscopic particle with at least one dimension less than 100 nm) so that it can target these cancer cells without, crucially, interfering with normal cells - and report that they've stopped cancer cells from spreading in mice. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields.
India’s tiger population has risen from 1,706 individuals to 2,226 in the past four years, officials have reported. With the global population teetering around 3,000 individuals, this kind of growth is incredible.
High-speed video footage has captured for the first time, what researchers say are hundreds of tiny aerosol particles being released from raindrops when they impact with soil.
The mechanical engineers at the Massachusetts Institute of Technology, who observed the aerosol release in action, say it could account for the earthy smell that accompanies rain after a long dry spell.
According to a recent study conducted by researchers at the University of Grenoble in France, the results published were plain and simple - men who enjoyed dipping their food into hot, spicy sauce happened to have higher levels of free testosterone floating around their bloodstream after the meal. Salt preference, however, didn’t seem to have any link to testosterone levels. What does this correlation entail? Does capsaicin - the chemical responsible for spiciness - increase testosterone, or are those who are more likely to take risks possess higher levels of this potent male hormone? [ ... ]
A parasitic worm called Onchocerca volvulus affects 25 million people around the world in one of the most revolting ways possible. The larvae of this tiny worm, found in sub-Saharan Africa and Latin America, can live for more than 10 years in a person’s skin, and that’s not even the worst part - they often make their way into their eyes.
Have you ever chillaxed (chilling and relaxing ) under the sun, cloud watching, and all of a sudden noticed transparent blobs floating around? Did you know what these things were? I know I didn't until I saw this:
I'd like to share this mind-opening video. Astrophysicist Dr. Neil DeGrasse Tyson was asked by a reader of TIME magazine, "What is the most astounding fact you can share with us about the Universe?" This is his answer. By far, one of the best...
