Overview[ edit ] In the scientific methodan experiment is an empirical procedure that arbitrates competing models or hypotheses. However, an experiment may also aim to answer a "what-if" question, without a specific expectation about what the experiment reveals, or to confirm prior results. If an experiment is carefully conducted, the results usually either support or disprove the hypothesis.
January[ edit ] 2 January The study, based on planets orbiting the star Keplersuggests that planetary systems may be the norm around stars in our galaxy. These outflows, which extend as far as 50, light-years from the galactic planeare thought to be fuelled by intense star formation.
OLED screens are thinner, more efficient and capable of displaying images with greater definition than conventional LCD and plasma screens. At such temperatures, matter begins to exhibit previously unknown qualities.
Following additional testing, the treatment could be used to heal human sufferers of retinitis pigmentosa. Among the new technologies showcased are flexible tablet computersautonomous cars, medical telepresence robotsultra-definition TVs and high-efficiency microchips. The company plans to mount the laser on a variety of vehicles for battlefield use.
The exocomets were discovered using the McDonald Observatory in Texaswhich imaged the chemical signatures of the comets' tails.
The rifle is also Wi-Fi -enabled, and its software can record its aiming and firing historypotentially allowing law enforcement agencies to track its use.
The invention could be used to precisely fashion new medicines or polymers. The city's air contains as much as 20 times the World Health Organization 's recommended amount of toxic particles.
Three functional reaction wheels are needed to accurately aim the telescope; one of Kepler's original four reaction wheels failed in July If this second wheel issue is not resolved, NASA may be forced to end the long-running Kepler mission altogether.
The building will be constructed of a high-strength artificial marble laid down by an industrial-scale 3D printer, and is planned for completion in The company intends to launch its first prospecting spacecraft in DNA has immense potential as a storage medium, and may become commercially available for this purpose in the near future.
The invention could have broad applications in medicine and microbiology. This breakthrough may lead to more effective treatments for human stroke sufferers. South Korea conducts its first successful orbital launch with its indigenous Naro-1 rocket replica pictured.
This reactivity may be crucial to developing new practical applications for graphene, which is already widely known for its immense strength and conductivity. In addition, they were able to manipulate cellular electric charge levels to prevent certain cells from developing cancer.
If human trials prove successful, this treatment could allow older people to more effectively resist disease.
The aerial surveillance robot weighs just 16 grams, and can be remotely piloted into difficult terrain to detect hidden enemy positions. The station, which is mounted on hydraulic ski-legs to allow it to be towed across the ice, features an advanced modular design and is expected to endure the Antarctic climate until These could both replace conventional ready meals and allow astronauts to enjoy a far more varied diet.
Additionally, some such exoplanets may exist only 13 light-years from Earth.Below is a list of important scientific experiments and the scientist who conducted them.

Gartner worked with plants in his experiments, including peas, which may have inspired Mendel to work with the same plant.  Pea plants were a common and good choice for hybridization experiments because they normally self-pollinate. Why a Scientific Format?
The scientific format may seem confusing for the beginning science writer due to its rigid structure which is so different from writing in the humanities. One reason for using this format is that it is a means of efficiently communicating scientific findings to the broad community of scientists in a .
Scientists can perform a process called polymerase chain reaction in the lab in order to copy DNA inside a test tube. This method is part of creating a DNA fingerprint of a suspected criminal. Cells from the suspect's cheek are placed into a tube.
