Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Conversion of Units

Sometimes, there is a need to convert from one unit to another one. For instance, reading a cookbook in which quantities are expressed in units of liters or ounces may require conversion of quantities to cups. Or, when looking up directions on how to get to a location, we may be interested to know how many miles we are going to walk. In this case, we would have to convert units of feet or meters to miles. The first step in the unit conversion is to list the given units and the units required...

Source: J. Jacob Chavez, Ryan T. Davis, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Thermal expansion is extremely important when considering which materials will be used in systems that experience fluctuations in temperature. A high or low thermal expansion in a material may or may not be desirable, depending on the application. For instance, in a common liquid thermometer, a material with a high thermal expansion would be...

We describe a novel method to perform DNA replication via the polymerase chain reaction (PCR). Thermal convection is harnessed to continuously shuttle reagents between denaturing, annealing, and extension conditions by maintaining opposing surfaces of the reactor at constant temperature. This inherently simple design promises to make rapid PCR more accessible.
FAQs
The activation barrier determines how much supplied heat is needed to promote the reverse pathway. As temperature rises, thermal energy can become sufficient to overcome that barrier, allowing the material or system to move away from its converted condition. This relationship helps engineers evaluate when recovery, resetting, or reversal may occur during thermal operation.
Temperature is a central condition because it controls the thermal energy available to the system. The material, its converted state, and the operating conditions also influence whether the reverse reaction, phase transition, or energy-transfer pathway proceeds. Considering these factors together helps engineers distinguish a controllable return from a change that does not occur under the intended conditions.
The reverse change does not have one universal mechanism. Depending on the engineered material or system, heating may promote a reverse reaction, a phase transition, or an energy-transfer pathway. Identifying which pathway is active matters because it determines what changes should be evaluated, how the system returns toward its original state, and how thermal behavior should be interpreted.
Cycle stability depends on how reliably a system can move between converted and original conditions as thermal conditions are applied and removed. Examining back-conversion across repeated operating cycles helps reveal whether the material or system can recover or reset consistently. This assessment supports decisions about functional-material design, thermal control, and the practicality of reversible technologies.
A useful evaluation begins by identifying the converted condition and the original condition that the system is expected to approach. Engineers then examine the effect of rising temperature under defined operating conditions, determine which reverse pathway is involved, and assess the resulting return or reset behavior. Comparing these observations across cycles can clarify controllability and stability.
Engineering applications include heat-induced changes in functional materials, thermal management, materials processing, and technologies designed to recover or regulate stored energy. In each case, the process provides a way to consider how heating changes a system and whether that change can support recovery, resetting, or control. Its value depends on matching the thermal behavior to the intended system function.
