A procedure for creating and imaging capillary bridges in slit-pore geometry is presented. The creation of capillary bridges relies on the formation of pillars to provide a directional physical and chemical heterogeneity to pin the fluid. Capillary bridges are formed and manipulated using microstages and visualized using a CCD camera.

Effective traps to attract and capture the emerald ash borer (EAB) are a key element of detecting and managing this invasive pest. Double-decker traps, placed in full sun near ash trees, incorporate visual and olfactory cues and were more likely to capture EAB than other trap designs in field trials.

Fixing Double-strand Breaks

The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Source: Laboratories of Gary Lewandowski, Dave Strohmetz, and Natalie Ciarocco—Monmouth University A factorial design is a common type of experiment where there are two or more independent variables. This video demonstrates a 2 x 2 factorial design used to explore how self-awareness and self-esteem may influence the ability to decipher nonverbal signals. This video leads students through the basics of a factorial design including, the nature of a factorial design and what distinguishes it from...

What is an Experiment?

An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

The pattern appears because each possible route contributes a probability amplitude, and the amplitudes from the two openings combine. Where they reinforce one another, the screen records a bright fringe; where they cancel, it records a dark fringe. This alternating structure is therefore not simply a pair of images from the openings, but an interference result of their combined contributions.
When an experiment determines which slit a particle uses, the interference pattern disappears. The measurement supplies path information that changes the observed behavior from a combined two-slit pattern to particle-like detection without those alternating fringes. This result makes measurement central to interpreting how quantum systems produce observable outcomes.
Coherent illumination gives the contributions from the two slits a relationship that allows them to form a visible, stable interference pattern. Without that condition, the experiment would not provide the same clear bright and dark fringe structure described for the demonstration. Coherence is therefore an important preparation condition when using light.
A basic arrangement sends coherent light, electrons, or other quantum particles toward a barrier containing two narrow openings. A screen placed beyond the openings records where the particles or waves arrive. Researchers then examine whether the screen shows alternating bright and dark fringes and compare that result with whether slit use was measured.
Using light and using electrons tests the same two-slit principle with different physical systems. The experiment can reveal wave-like interference for both, while detections still identify localized outcomes on the screen. Its importance is that wave-particle duality is not limited to light; it also appears in matter such as electrons.
In physics, the experiment serves as evidence for quantum mechanics because it connects measurable screen patterns with the effect of measurement on those patterns. It also frames questions about how quantum interpretations describe measurement and where the boundary between classical and quantum physics should be considered. Thus, it supports both demonstration and foundational research.
