Who discovered the 2009 H1N1 flu virus?

It was a team effort. Teams of scientists from the Centers from Disease Control and Prevention (CDC), World Health Organization (WHO), and public health departments from several other nations worked together to identify and isolate the virus that was causing the outbreak in Mexico, California and Texas in the US.

One of the scientists mentioned to have been involved in the analysis was the leading virologist, Wendy Barclay, who on May 1, 2009 determined that there were characteristics of the virus that resembled other viruses that had caused only mild symptoms and she indicated that this new 2009 H1N1 influenza was unlikely to give most people serious symptoms.

It was just prior to that when on April 27, 2009 the CDC Scientists in Atlanta were able to document the genome sequence of the new strain to share with other scientists in their databases. Not long afterward, on May 6, 2009, Canadian scientists from Winnipeg were able to share the full genetic sequencing of the viruses that had struck Mexico and Canada.

The scientists all over the world remain very busy working and sharing information to further various studies of the pandemic flu still underway.

What were Nikola Tesla's struggles along the way?

Nikola Tesla faced financial difficulties throughout his career, often struggling to fund his experiments and projects. He also experienced challenges gaining widespread support and recognition for his revolutionary ideas, facing skepticism and opposition from competitors and investors. Tesla's unconventional approach to science and his focus on long-term, high-risk projects further complicated his efforts to secure funding and support.

What do scientists test with pH?

Scientists test the acidity or alkalinity of a substance using pH levels. This measurement helps determine the concentration of hydrogen ions in a solution. pH is important in various fields such as chemistry, biology, and environmental science.

What might a scientist do in order to help visualize an atom?

A scientist can use computer simulations or models to visualize an atom. These tools can depict the structure of an atom, including the arrangement of its subatomic particles like protons, neutrons, and electrons. Additionally, techniques like scanning tunneling microscopy can provide real-time images of atoms.

When are non-polar molecule formed?

When

  • Atoms of the same element are bonded together, they show no polarity. Some common examples include oxygen, nitrogen, chlorine as diatomic molecules and ozone as a triatomic molecule.
  • The dipole effect of polar bonds in a molecule "cancel" each other out due to the geometry of the molecule, e.g. CF4

Who wins Tesla or Edison?

In terms of their contributions to electrical engineering, both Tesla and Edison made significant impacts. Tesla's inventions laid the foundation for modern AC electrical systems, while Edison is known for his work on the incandescent light bulb and DC electrical systems. Ultimately, their legacies are both important in the history of technology.

Can a scientist see atoms?

No, scientists cannot directly see atoms because of their very small size. Instead, scientists use techniques like scanning electron microscopes or atomic force microscopes to indirectly visualize atoms and their structures.

Why scientist concluded that electrons revolve around nucleus and not neutrons?

The amount of experimental data relating to the relative location of protons, neutrons, and electrons in an atom is so vast that it would be difficult to know where to start. It is known that protons and neutrons attract each other by means of the strong nuclear force; without this attraction it would be impossible to have any atom with more than one proton in the nucleus, since protons repel each other. This requires neutrons to be in the nucleus, with the protons, not orbiting the nucleus. When atoms are ionized, we know they lose or gain electrons and not neutrons because they acquire an electric charge. There are thousands of other ways of confirming this.

What year did Louis Pasteur invent the treatmeant for rabies?

Vaccination did not have its origin with Edward Jenner. He learned of its efficacy from local folklore, and a Lady Margaret Montague who had her child vaccinated whilst in Turkey in 1718, where her husband was an UK official.

Vaccination had been practiced in India and China in much earlier years - according to an Indian medical text, perhaps as early as 1000 - 2000 BC.

Because of Jenner and Montague, vaccination against smallpox via a cowpox challenge, was becoming widespread, if somewhat sporadically, in the 1700s.

The word vaccine derives from Latin vacca for cow. And Pasteur named the products vaccines in honour of Jenner.

Pasteur went on to develop various other vaccines, and indeed in 1885 he applied an early variety of rabies vaccine to a child bitten by a rabid dog. Whether the child had indeed contracted the disease is debated, for even modern rabies vaccines are only considered worthwhile before the disease challenge.

What are three elements named after great scientists?

Einsteinium and mendelevium, Thorium, Curium, Fermium, Rutherfordium, Bohrium, Seaborgium, etc., etc.

What Tesla invented?

Nikola Tesla was a Serbian-American inventor and engineer who made significant contributions to the development of alternating current electrical systems. He also developed the Tesla coil, a high-frequency transformer that is still used in radio technology today. Tesla's work laid the foundation for modern wireless communication and electrical power systems.

Who are Jenner and pasteur?

Dr Edward Jenner was a physician and scientist who, late in the 18th century, gave a demonstration that cowpox pus from human beings could be used as a way of conveying immunity to smallpox in us.

Louis Pasteur was a 19th century chemist and microbiologist who invented pasteurisation and a special type of pipette, and who was responsible for various discoveries.

What is the percentage of male scientists?

As of the most recent data available, approximately 75% of scientists worldwide are male. This gender disparity is slowly improving, but there is still work to be done to achieve gender equality in the field of science.

How did Nikola Tesla make his inventions?

Nikola Tesla made his inventions through a combination of relentless experimentation, innovative thinking, and a deep understanding of scientific principles. He was known for his ability to visualize inventions in his mind before bringing them to life through meticulous planning and testing. Tesla also had a keen focus on practical applications, always striving to create inventions with real-world utility.

What do you call someone who studies oil?

A person who studies oil is called a petrologist or petroleum geologist. They specialize in the exploration, extraction, and production of oil and gas resources.
