Herbert Merrick. Herbert Lansing Merrick (April 16, 1873 – May 2, 1938) was an American engineer, inventor, and entrepreneur. He invented the first beltweighers, which automatically weigh bulk materials as they are passed along a conveyor belt without stoppage.

Early life and education 
Merrick was born in Brooklyn, New York, on April 16, 1873, to Charles Merrick and Anna Merrick. One of three brothers, Merrick attended Bergen County public schools before graduating from Stevens Institute of Technology in 1892 with a Mechanical Engineering degree. After graduation he would work as an engineer and draftsman at various companies before starting his own manufacturing company.

Career 
Intrigued by the need for simple conveyor scales that can accurately record weight, Merrick sought to invent a device that could fulfill that demand. In 1907, he designed an experimental conveyor scale called the 'Conveyor Weightometer' for Fraser & Chalmers, Ltd., who introduced the new device at a mining machinery exhibition in London the next year. After examinations and tests by British government officials, the Weightometer was issued a certificate of allowance for use as a legal weighing instrument in trade. 

Later in 1908, Merrick would rent a shop in Passaic, NJ, and immediately begin work on manufacturing the first Weightometers. Due to increased demand, Merrick expanded his factory in 1911 and incorporated his new business under the name Merrick Scale Manufacturing Company. 

Merrick's company is still in operation today under the name Merrick Industries, Inc., located in Florida, USA.

Personal life 
Merrick was married to Katherine Selleck, they had one daughter together named Alice. A member of the Republican Party, he was active in politics. Merrick was also a member of the First Reformed Church of Passaic and director of the People's Bank and Trust Company. He was an avid sailor and owned the 'Kathal,' a cruiser named after his wife and daughter. On May 2, 1938, Herbert Merrick passed away after a long illness. He was 65 years old.

Historical Aircraft Squadron. The Historical Aircraft Squadron is a non-profit organization located at the Fairfield County Airport in Carroll, Ohio focused on aviation history.

History 
The organization was founded in 1994. The following year, the organization considered building a museum with the promise that they might receive an airplane from Dave Tallichet. This came to pass in May 1998 when it was lent a Douglas A-26 Invader from his Military Aircraft Restoration Corporation. Eventually, it was joined by another A-26 and a North American B-25 Mitchell that were also placed on loan to the museum. The restoration of the first A-26 was completed in September 2009
and two years later left the museum for the 1941 Historical Aircraft Group Museum.

In the meantime, the organization built a new hangar at the airport in 2000, which it signed a 10-year lease for the next year. A Grumman S2F-1 Tracker was based with the squadron for a time in 2002. A plan for a church to build a new hangar at the airport in 2006 caused the museum to express concerns that it might lose some of its ramp space.

Verve PCSK9-inhibitor gene therapy. VERVE-101 and VERVE-102 are an experimental gene therapy developed by Verve Therapeutics that targets the PCSK9 gene and is intended to reduce blood cholesterol levels. It works on the same protein as the cholesterol-lowering drugs known as PCSK9 inhibitors but, unlike them, is permanent. It works via base editing, a form of CRISPR gene editing. It is one of the first gene therapies that could be beneficial to a wider segment of the population, in contrast to earlier gene therapies that were developed to treat a rare genetic disorder. Both treatments use the same RNA gene editing technology, but they use a different lipid nanoparticle delivery vehicle.

Biostimulant. Biostimulants also termed as plant conditioners or bioeffectors are substances, cultures of micro-organism, and mixtures of materials used to promote the growth of crop plants and can include natural or artificial plant growth regulators and biofertilizers. They do not include pesticides or fertilizers. The concept has been developed on the basis of the idea that plants are not isolated entities but grow within a complex ecosystem involving interactions with multiple organisms and that the strengths of these associations can be modified to enhance plant growth. The definitions vary but an attempted standard definition includes the statement that they are “a formulated product of biological origin that improves plant productivity as a consequence of the novel or emergent properties of the complex of constituents, and not as a sole consequence of the presence of known essential plant nutrients, plant growth regulators, or plant protective compounds.”

Although there are no widely-accepted definitions of the term, around eight categories of constituents have been recognized in the literature which include:

 Humic substances
 Nitrogenous substances including amino acids
 Non-essential chemical elements
 Inorganic salts
 Seaweed extracts
 Chitin and chitosan derivatives
 Antitranspirants
 Other complex organic materials

A review commissioned by the Agriculture and Horticulture Development Board also included biological agents under the definition and defined four categories of these: 

 Plant growth promoting bacteria and rhizobacteria
 Non-pathogenic fungi
 Arbuscular mycorrhizal fungi
 Non-pathogenic protozoa and nematodes

Regulation
 due to their being no agreed definition of the term biostimulant, there were no specific frameworks for regulating their use in any country. The regulation of production and use of these materials varies from country to country with some treating them under their fertilizer legislations.  in Europe, registration requirements differed substantially between countries with France, Italy and Hungary having relatively strict regulations which required evidence of efficacy and toxicity, Germany and Spain requiring only efficacy information and the UK requiring no efficacy or safety information.
