In the form of DNA, nature shows how data can be stored in a space-saving and long-term manner. Bioinformatics specialists are developing DNA chips for computer technology. Researchers show how a combination of molecular biology, nanotechnology, novel polymers, electronics and automation, coupled with systematic development, could make DNA data storage useful for everyday use possible in a few years.

Immunotherapies for cancer aim to induce the immune system to combat cancer cells more effectively. A research team has now described a new, modular strategy for T-cell-based immunotherapy that manages to work without complex genetic modifications. Modulation of cell-cell communications through an ingenious regulatory circuit using various small, specially folded DNA molecules (aptamers) causes cancer cells to directly activate their mortal enemies, T cells.

Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.

Recent research in cell biology highlights groundbreaking results. An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of the nuclear membrane. The microscopic force sensor, only about 0.00002 mm long, is constructed of exotic ingredients such as spider web protein parts, fluorescent proteins from jellyfish, and antibodies from alpaca. In addition, the multidisciplinary team of researchers has developed further the sensitivity of super-resolution microscopy technique.

Research attempts to quantify the value of U.S. property at risk in forested areas exposed to increased ecological disturbance associated with climate change, such as wildfire and tree mortality. Property exposed to such climate risks, especially in California, is project to climb substantially if emission-reduction measures are not taken.

Medications to treat various chronic diseases may hinder the body's ability to lose heat and regulate its core temperature to optimal levels. The loss of effective thermoregulation has implications for elderly people receiving treatment for illnesses like cancer, cardiovascular, Parkinson's disease/dementia and diabetes, particularly during hot weather, according to a review by a team of scientists.

In a development that could accelerate the discovery of new diagnostics and treatments, researchers have developed a versatile and low-cost technology for targeted sequencing of full-length RNA molecules. The technology, called TEQUILA-seq, is highly cost-effective compared to commercially available solutions for targeted RNA sequencing and can be adapted for different research and clinical purposes.
