Far‐UV emissions from the SL9 impacts with Jupiter
No full textObservations with the International Ultraviolet Explorer (IUE) during the impacts of the fragments of comet D/Shoemaker-Levy 9 with Jupiter show far-UV emissions from the impact sites within a similar to 10 min time scale. Positive detections of H-2 Lyman and Werner band (1230-1620 Angstrom) and H-Ly alpha emissions are made for impacts K and S, and marginally for P2. No thermal continuum is observed. The radiated far-UV output was >10(21) ergs. The H-2 spectrum is consistent with electron collisional excitation if significant CH4 absorption is included. Such emissions could result from plasma processes generated by the impacts. Non-thermal excitation by the high altitude entry and explosion shocks may also be relevant. Emissions by Al+ (1671 Angstrom) and C (1657 Angstrom) of cometary origin are tentatively identified

During his time with the Mail System he continued to take various Civil Service exams and eventually, in August of 1938(39) he was given an appointment at the US Weather Bureau. This was his introduction to science and meteorology. Gerson worked as a meteorological observer in the Boston office, casting maps of current weather conditions to be printed for distribution. The Bureau eventually assigned Gerson to San Juan, Puerto Rico so that he could go to the University of Puerto Rico at night to earn his degree in Physics. While in San Juan, Gerson worked at the Hurricane Center, releasing radiosohn balloons all night and sending the data gathered to Washington, D.C. When his degree was complete, Gerson moved to a Weather Bureau job in Washington, D.C, where he developed equations for determining the pressure altitude of planes with Louis P. Harrison. He then moved on to the US Army Air-Force in 1946 and worked in the Watson Laboratories in New Jersey, dealing with radar navigation systems. George W. Kendrick was the Chief Scientist at Watson and the key project Gerson worked on was the development of a low frequency, long-wave navigational system to cover the Arctic (known to the Army as Operation Musk Ox, then MUSCALF, and finally Project Beatles). This eventually developed into the LORAN-C system of navigation. Gerson describes his time north of the Arctic Circle in detail, particularly his calibration of the various stations and outposts. He also discusses the fur trade that was taking place in Northern Canada, with particular emphasis on wolf and polar bear pelts.
Gerson eventually moved on to Fort Monmouth in New Jersey and began working on the LF noise intensities in the North American sub-Arctic. Additionally at this time his writing revolved around the refractive index in polar regions and its effect on radio noise. While working at Fort Monmouth, Gerson also earned his Master’s degree from NYU in Physics. Ultimately, Gerson’s work at Fort Monmouth led to his promotion to head of the Propagation Laboratory, an extension of the Watson Laboratory, which was part of the Army-Air Force Laboratories. During his time at Watson, Gerson became interested in geophysics, studying the nocturnal ionization in the F2 layer. In 1947, the Army-Air Force split, becoming the USAF. The USAF took over operations at Watson Laboratories, moving the engineering sector to Griffis Air Force Base in Rome, New York as the RADC (Rome Air Development Center) and moving the geophysics sector to Boston as the Air Force Cambridge Research Center. Gerson went to Boston and took charge of the Ionospheric Physics Laboratory. He discusses the development of a photographic balloon program and the effect this laboratory had on foreign relations. Additionally, Gerson describes the ionosphere, ionization of air particles, and the use of an ionosohn dropped from airplanes.
As time progressed, Gerson began to work with a German physicist named Dr. Demigar on the issue of polar cap absorption. He presented his work to an international audience at the Hague in the Netherlands, with the primary discovery elucidated being protons and electrons causing ionization of oxygen by spiraling down the magnetic lines of force and colliding with oxygen atoms on both the dark and sunny side of the earth. This causes the auroral zones seen at the Poles. This work led to the production of the first flying laboratory in the United States, which Gerson equipped. As IGY approached, the idea of a polar flying laboratory was talked about. This eventually led to a somewhat modified flying lab, used for making necessary measurements to be taken back to the South Pole base. Gerson was made Chairman of the first two Antarctic committees, the first to justify going and the second to implement the trip. He spends a good amount of time describing these meetings, the proceedings, who attended, among other details, beginning in 1953. Ultimately, Gerson spent his time studying auroral physics during IGY.

Chronic Fatiguing Illnesses: Entering the era of new biomarkers and therapies
No full textIllnesses characterized by chronic fatigue are often defined by symptoms and not by objective biomarkers that support both diagnosis and treatment. Without readily obta ined b io marke rs, c linica l ma na ge me nt ca n be compromised by lack of certainty. This uncertainty creates a wide spectrum of possible therapies that in many cases is reduced to trial and error medicine, resulting in patient frustration and resource exhaustion, with little improvement in health status. Modern medicine must leverage modern science to bring common research tools into the clinic for patient diagnostics. Using biomarkers previously confirmed as useful in diagnosis and treatment of chronic inflammatory response syndrome (CIRS), including transcriptomics, the authors present evidence of benefit in assessment of a “symptoms-only illness.” These immune biomarkers, such as transforming growth factor beta (TGFb), vasoactive intestinal peptide (VIP), melanocyte stimulating hormone (MSH), split produc ts o f co mp le me nt act ivat io n, and ma ny ot hers disc ussed he re, are now a va ilab le for use a s c linica l diagnostics, but rarely ordered in cases of chronic illness. In cases of cognitive decline, new technology for brain MRI analysis, NeuroQuant, can pick up small changes in brain structures that are frequently missed by radiologists, but consistently shown in CIRS. By focusing on persistent symptoms seen in antibiotic-treated Lyme disease (Post-Lyme Syndrome, PLS), CIRS-biomarkers have utility to define both an initial infectious process and a subsequent inflammatory illness. Genomic testing can determine predisposition to chronic stages of Lyme after acute illness and use of Next Generation Sequencing now brings transcriptomics to the Lyme community, to assess remaining abnormalities at any given treatment stage of PLS. Application of these new, object ive tes t ing o ffe r ings w ill re vea l t he mo le c ular pathophysiology of illness, avoiding over-reliance on symptoms and antibody testing alone. This will help providers direct highly targeted therapies on an individual basis, in this era of personalized medicine

Interview of David C. Nutt by Brian Shoemaker
No full textIn 1935, David Nutt (David), while attending the Hotchkiss Prep School in Connecticut, attended a lecture by Capt Bob Bartlett on the Arctic. Bob was a legendary figure who explored with Robert Peary, Vilhjalmur Stefansson and others. As a result he went to Greenland with Bartlett aboard the RV Effie M. Morrisey for five trips in the summers of 1935 thru 1940. Nutt lists Bartlett as a mentor as well as Waldo Schmidt of the Smithsonian Institution. In June of 1941, David graduated from Dartmouth. He was already in the Naval Reserve and was called to active duty the month before graduation. The Navy detailed David as Executive Officer to the USS Bowdoin, formerly the RV Bowdoin that was sailed by McMillan to the Arctic on numerous occasions. The Bowdoin was fitted out to do hydrographic surveys and in 1942 and 43 conducted hydrographic work in Greenland waters – most notably the hydrographic soundings of Sondestrom Fjord where the American base Bluie West Eight was located and other fjords where U.S. bases were established. In 1944, David was detailed as Executive Officer aboard the USS Sumner, a fleet hydrographic vessel. In early 1945 he became the Commanding Officer of the Sumner. It was the first U.S. ship to enter North China since 1927 and later was the first U.S. ship to enter Bikini Atoll since 1940. He and his crew completed the hydrography of the atoll. He was released from active duty in 1946. Captain Nutt, purchased the Blue Dolphin from Amory Coolidge after returning to New England. It was fitted out as a hydrographic ship by the Navy. He used the vessel on Office of Naval Research Contracts for a variety of scientific research projects in the Arctic. Among his Principal Investigators were Larry Coachman, Per Scholander, Dick Backus and others. He describes the work that was performed on the Blue Dolphin in detail in the interview. He was recommended for Operation Windmill by Waldo Schmidt of the Smithsonian Institution. Windmill was a follow-on expedition to Antarctica to establish survey control points for the aerial photography taken during “Operation High Jump.” Captain Nutt sailed to the Antarctic aboard the USS Edisto in 1947- 48 as a naval observer and curator for the Smithsonian Institution. Capt Nutt sold the Blue Dolphin in 1961, but continued Arctic research project for many years afterward. He served on the Board of Governors of the Arctic Institute of North America and the American Polar Society for many years. He is retired, near Dartmouth in the of Etna, NH where he has lived for the past 55 years.Funded by a grant from the National Science Foundation
