Research with human participants, particularly in experiments that involve modulating brain function, is never taken lightly in the United Kingdom.
The analysis is further extended through experiments that involve the use of additive manufacturing.
Experiments that involve XRD, atomic force microscopy and X-ray photoelectron spectroscopy provide structural information on the designed heterostructures.
Additional causal experiments that involve inactivation or perturbation of PMd during a decision-making task are necessary to resolve this question68 (Supplementary Note 8).
The first reason is that it is a very useful tool for run-of-the-mill experiments that involve engineering and studying lab-grown cells.
Senator Arlen Specter, Republican of Pennsylvania, has introduced legislation to authorize the National Institutes of Health to pay for embryonic stem cell research, including experiments that involve the destruction of embryos.
The researchers say that their findings do not prove cause and effect and experiments that involve giving asthma sufferers vitamin supplements have proved disappointing.

The researchers also said experiments that involve studying the AIDS virus in mice could be misleading because the virus could be altered by coming into contact with mouse viruses.
Because of the one-directional motion of the atoms or molecules, their properties can be studied in experiments that involve deflecting the beam in electric and magnetic fields or directing the beam onto a target.
