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.

Dead or depleted batteries, especially cylindrical ones like AA or AAA batteries, can exhibit a unique behavior known as "bouncing" when dropped from a short height. This phenomenon is primarily due to changes in the battery's internal chemistry and physical properties as it becomes discharged.

Inside a battery, there are chemical reactions that generate electrical energy. As a battery discharges and its chemical energy is depleted, its internal chemistry changes. One of the changes that occur is a reduction in the pressure of gases within the battery. This decrease in gas pressure can make the battery feel lighter, contributing to its bounce.

As a battery discharges, its internal components, such as the cathode, anode, and electrolyte, unde ...

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:

In a paper this week in Science, two scientists at John Hopkins have united biology and mathematics to propose a mathematical formula to explain the genesis of cancer.


Take the number of cells in an organ, identify what percentage of them are long-lived stem cells, and determine how many times the stem cells divide. With every division, there’s a risk of a cancer-causing mutation in a daughter cell. Thus, Tomasetti and Vogelstein reasoned, the tissues that host the greatest number of stem cell divisions are those most vulnerable to cancer. When Tomasetti crunched the numbers and compared them with actual cancer statistics, he concluded that this theory explained two-thirds of all cancers.

“Using the mathematics of evolution, you can really ...
