- 'Body hack' app by math researchers shortcuts jet-lag recovery
- A different kind of jet-lag mobile app released today by mathematicians reveals previously unknown shortcuts that can help travelers snap their internal clocks to new time zones as efficiently as possible.
- Virus structure inspires novel understanding of onion-like carbon nanoparticles
- Symmetry is ubiquitous in the natural world. It occurs in gemstones and snowflakes and even in biology, an area typically associated with complexity and diversity. There are striking examples: the shapes of virus particles, such as those causing the common cold, are highly symmetrical and look like tiny footballs.
- Should you trust your financial advisor? Pseudo-mathematics and financial charlatanism
- Your financial advisor calls you up to suggest a new investment scheme. Drawing on 20 years of data, he has set his computer to work on this question: If you had invested according to this scheme in the past, which portfolio would have been the best? His computer assembled thousands of such simulated portfolios and calculated for each one an industry-standard measure of return on risk. Out of this gargantuan calculation, your advisor has chosen the optimal portfolio. After briefly reminding you of the oft-repeated slogan that "past performance is not an indicator of future results," the advisor enthusiastically recommends the portfolio, noting that it is based on sound mathematical methods. Should you invest?
- Technical tests of biodiversity: When physicists play with genetics of populations
- The effect of migration on biodiversity (intended as the coexistence of different genetic traits) is an open question: does migration increase or decrease the genetic variability of populations? Or is the relationship more complex than that? A team of physicists has developed and analyzed a model that simulates the effect of migration on the genetic biodiversity of populations, and discovered that the effect is all but trivial.
- Method offers potential for understanding anti-bacterial resistance
- Biologists could gain a deeper understanding about how species have evolved -- and even find ways to address antibiotic resistance -- using tools that were recently developed. By basing their methods on mathematical models and Bayesian analysis, the researchers succeeded in producing tools for biologists who are interested in jumping genes and the traits they carry with them.
- Synthetic genetic clock keeps accurate time across a range of temperatures
- A long-standing challenge in synthetic biology has been to create gene circuits that behave in predictable and robust ways. Mathematical modeling experts and experimental biologists have now created a synthetic genetic clock that keeps accurate time across a range of temperatures.
- 'Unbreakable' security codes inspired by nature
- A revolutionary new method of encrypting confidential information has been patented by scientists inspired by their discoveries from human biology, which model how the heart and lungs coordinate their rhythms by passing information between each other.
- Overcoming structural uncertainty in computer models
- A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for a particular problem can rarely be defined with certainty. The most we can do to mitigate error is to quantify the uncertainty in the model. Scientists have now offered a method to incorporate judgments into a model about structural uncertainty that results from building an 'incorrect' model.
