New research finds link between height and cancer

Why? Because you have more cells, the study suggests.

  • A new study is out suggesting that the taller you are, the more at risk you are of certain types of cancers.
  • The reason for this is a surprisingly simple one: you have more cells.
  • 18 of 23 studied cancers saw a relation between height and cancer risk.

10 paradoxes that will stretch your mind

From time-traveling billiard balls to information-destroying black holes, the world's got plenty of puzzles that are hard to wrap your head around.

Big Think
  • While it's one of the best on Earth, the human brain has a lot of trouble accounting for certain problems.
  • We've evolved to think of reality in a very specific way, but there are plenty of paradoxes out there to suggest that reality doesn't work quite the way we think it does.
  • Considering these paradoxes is a great way to come to grips with how incomplete our understanding of the universe really is.

  • A French study of nearly 70,000 people states that organic foods reduce the risk that you'll develop non-Hodgkin's lymphoma and postmenopausal breast cancer.
  • Agricultural pesticides have been shown to have a toxic effect on the human endocrine system.
  • The high cost of organic food remains a barrier to entry for those wishing to eat a healthier diet.

Cancer researcher says keto is not a fad diet

Anatomy and physiology professor David Harper claims a recent study in The Lancet is flawed.

  • The low-carbohydrate group in a recent Lancet study were typically middle-aged, obese, sedentary, diabetic smokers.
  • The study was not a randomized, controlled, double-blind experiment.
  • Harper has been in ketosis for six years, and says it has profound effects on cancer patients, among other chronic ailments.

Single algae cells can help deliver targeted medicine

Tiny and efficient, these biodegradable single cells show promise as a way to target hard-to-reach cancers.

  • Scientists in Germany have found a potential improvement on the idea of bacteria delivering medicine.
  • This kind of microtargeting could be useful in cancer treatments.
  • The microswimmers are biodegradable and easy to produce.

Metin Sitti and colleagues at the Max Planck Institute in Germany recently demonstrated that tiny drugs could be attached to individual algae cells and that those algae cells could then be directed through body-like fluid by a magnetic field.

The results were recently published in Advanced Materials, and the paper as a whole offers up a striking portrait of precision and usefulness, perhaps loosely comparable in overall quality to recent work done by The Yale Quantum Institute. It begins by noting that medicine has been attached to bacteria cells before, but bacteria can multiply and end up causing more harm than good.

A potential solution to the problem seems to have been found in an algal cell: the intended object of delivery is given a different electrical charge than the algal cell, which helps attach the object to the cell. The movement of the algae was then tested in 2D and 3D. (The study calls this cell a 'microswimmer.') It would later be found that "3D mean swimming speed of the algal microswimmers increased more than twofold compared to their 2D mean swimming speed." The study continues —

More interestingly, 3D mean swimming speed of the algal microswimmers in the presence of a uniform magnetic field in the x-direction was approximately threefolds higher than their 2D mean swimming speed.

After the 2D and 3D speed of the algal was examined, it was then tested in something made to approximate human fluid, including what they call 'human tubal fluid' (think of the fallopian tubes), plasma, and blood. They then moved to test the compatibility of the microswimmer with cervical cancer cells, ovarian cancer cells, and healthy cells. They found that the microswimmer didn't follow the path of bacteria cells and create something toxic.

The next logical steps from the study include testing this inside a living organism in order to assess the safety of the procedure. Potential future research could include examining how effective this method of drug delivery could be in targeting "diseases in deep body locations," as in, the reproductive and gastrointestinal tracts.
