1. Laboratory

   A laboratory is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. Labs used for scientific research take many forms because of the differing requirements of specialists in the various fields of science. A physics lab might contain a particle accelerator or vacuum chamber, while a metallurgy lab could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's lab might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers are used for either simulations or the analysis of data collected elsewhere. Scientists in other fields will use still other types of laboratories. Despite the great differences among laboratories, some features are common. The use of workbenches or countertops at which the scientist may choose to either sit or stand is a common way to ensure comfortable working conditions for the cabinets for the storage of laboratory equipment is quite common. It is traditional for a scientist to record an experiment's progress in a laboratory notebook, but modern labs almost always contain at least one computer workstation for data collection and analysis.

1. laboratory

   A department which is intrusted with the manufacture of combustible and other substances for military purposes, such as blank and ball cartridges for small-arms, cartridges for every description of ordnance, rockets, and all stores of similar character. This department is likewise intrusted with the conservation, packing, restoring, and supply of all gunpowder to the several military and naval departments, and in the British service is under the management of officers of the royal artillery especially appointed to that duty; in the U. S. service it is under the officers of the ordnance department. In the latter service officers of artillery, as well as non-commissioned officers and privates, are instructed at the artillery school, Fort Monroe, Va., in laboratory duties, and carefully taught the manipulation and manufacture of laboratory stores. At the West Point Military Academy, the cadets are thoroughly instructed in the above duties, as are also the naval cadets at the Naval Academy, Annapolis, Md. In the British service officers of artillery, as well as non-commissioned officers and gunners, are instructed in laboratory duties. Officers and non-commissioned officers of artillery in Germany, France, and Austria are required to possess a knowledge of the manufacture and care of laboratory stores.

Examples of laboratory in a Sentence

1. Dave Barry:

   What happens if a big asteroid hits Earth ? Judging from realistic simulations involving a sledge hammer and a common laboratory frog, we can assume it will be pretty bad.

2. Theodor Herzl:

   The body is a marvelous machine...a chemical laboratory, a power-house. Every movement, voluntary or involuntary, full of secrets and marvels

3. Christopher Rolfe:

   The demands of modern engines and modern hardware mean that the complexity of our formulations is increasing. We have to experiment with various different materials and determine the best blending methods so they can be replicated globally, once the formulation has been sent over from the laboratory, we would then take that formulation and work out how to blend it. The blending methods here get replicated globally, so the understanding of the hardware and the engines that takes place in the laboratory, is then transferred into real-world applications in the blend shop here.

4. Albert Einstein, quoted in Scientific American, September 2004, page 69:

   No one but a theorist believes his theory; everyone puts faith in a laboratory result but the experimenter himself.

5. Marcus Low:

   It leaves us with one less caregiver to be on assignment, and that leaves us short-staffed. Public health experts say testing delays present a major hurdle to reducing infections and tracking those who have been in close contact with a person who is positive for the virus. Thats why researchers are working to develop rapid tests that can be cheaply produced, self-administered and provide immediate, reliable results. For now, most tests to diagnose COVID-19 require laboratory processing, which means a built-in delay. Guidelines issued by the Centers for Disease Control and Prevention recommend that states, as they lift final virus restrictions, have a turnaround time of less than two days. But its unclear whether states have access to detailed data showing whether they are meeting the CDC standard, including how long it takes to process tests at independent labs. Labs track their own turnaround times, but the CDC said data such as how long it takes for a test to get to a lab and for a provider to receive the result and notify the patient are not tracked. That makes it difficult to determine a meaningful average of what patients are experiencing in each state. In the absence of publicly available federal data, the AP earlier this month surveyed nine states that were experiencing a 14-day uptick in new positive cases, plus New York, which has had the most COVID-19 cases. The state lab in New York was taking up to three days to report results to patients. California officials said the statewide turnaround time was 48 to 72 hours, depending on the lab. In Utah, anecdotal information suggested that results took 24 to 72 hours. Most of the 10 states surveyed said they did not have data on turnaround times for commercial labs in their state, creating another information gap. Health experts said this was not unusual, that state health departments have not typically been responsible for tracking individual laboratory turnaround times. Its a good question of who should be responsible for tracking this information and providing it back to the public, said Kelly Wroblewski, director of infectious diseases with the Association of Public Health Laboratories. There are other factors that can cause delays, from the time of day the test is taken to whether a lab shuts down for the evening. Staffing issues and shortages of testing supplies also can slow the process. Even people visiting the same testing location can have widely different experiences. Earlier this month, Jeff Barnes, a music therapist in metro Atlanta, went to the same drive-thru testing location a week after his wife and two daughters. They were still waiting when he received his results the next day. Theirs wouldnt come for seven days. Barnes said he was concerned what a similar delay would mean if schools reopen in the fall. They are going to have to make it more efficient, Barnes said. If I knew (my daughter) was in a classroom with 20 kids and 10 of them had results pending, I dont know that I would send her. Until rapid tests are widely available, health experts say it will continue to take a day or two to get results under the best circumstances. That creates more opportunities for people who might be infected but feel fine to pass the virus along to others. In late April and May, the state lab in Alabama had trouble acquiring reagents, the chemical substances used to process tests. That led to intermittent delays in reporting results, up to five days from when the lab received the specimen, according to Dr. Karen Landers, assistant state health officer with the Alabama Department of Public Health. Those problems have since been resolved, and the lab now has a turnaround time between 24 and 72 hours from the time it receives samples. One of the largest commercial laboratories, Quest Diagnostics, recently reported its average turnaround time as one day for priority patients and two to three days for all other populations. The company said it expects increased demand to result in longer waits of more than thee days. Other countries face similar challenges. Wait times in China vary by city, from as little as one day in Shanghai to four days in Wuhan, where the virus first emerged. In Japan, tests usually yield results within two days. Mandatory tests, such as those at airports, often come out sooner, according to the health ministry. Results in India initially took around 24 hours. But as infections and testing increased, so did delays. Now results often take two to three days or as long as a week, depending on location. The nearly two-week wait in South Africa makes effective treatment nearly impossible.
