(Press-News.org) Alaskans and visitors may be able to see an artificial airglow in the sky created by the High-frequency Active Auroral Research Program during a four-day research campaign that starts Saturday.
Scientists from the University of Alaska Fairbanks, Cornell University, University of Colorado Denver, University of Florida and Georgia Institute of Technology will conduct a variety of experiments at the UAF-operated research site.
The experiments will focus on the ionosphere, the region of the atmosphere between about 30 and 350 miles above the Earth’s surface.
Scientists will investigate ionosphere mechanisms that cause optical emissions. They’ll also try to understand whether certain plasma waves — gas so hot that electrons get knocked off atoms — amplify other very low frequency waves. And they’ll investigate how satellites can use plasma waves in the ionosphere for collision detection and avoidance.
Each day, the airglow could be visible up to 300 hundred miles from the HAARP facility in Gakona. The site lies about 200 miles northeast of Anchorage and 230 miles southeast of Fairbanks, or about 300 to 350 kilometers.
HAARP creates airglow by exciting electrons in Earth’s ionosphere, similar to how solar energy creates natural aurora, with on and off pulses of high-frequency radio transmissions. HAARP’s Ionospheric Research Instrument, a phased array of 180 high-frequency antennas spread across 33 acres, can radiate 3.6 megawatts into the upper atmosphere and ionosphere.
The airglow, if visible, will appear as a faint red or possibly green patch. Because of the way the human eye operates, the airglow might be easier to see when looking just to the side.
HAARP will create an airglow at a specific point in the sky. The angle of visibility for anyone wanting to look for it will depend on a person’s distance from HAARP.
HAARP transmission frequencies will vary but will occur between 2.8 and 10 megahertz. Actual transmit days and times are highly variable based on real-time ionospheric and/or geomagnetic conditions.
Additional information about the research campaign will be available on the HAARP website.
The National Science Foundation in 2021 awarded the UAF Geophysical Institute a five-year, $9.3 million grant to establish the Subauroral Geophysical Observatory at HAARP. The observatory explores Earth’s upper atmosphere and geospace environment.
The grant has supported several HAARP research campaigns, including this one. It also helped fund the return to HAARP of the Polar Aeronomy and Radio Science Summer School, which hosted more than 50 researchers in August.
The Air Force originally developed and owned HAARP but transferred the research instruments to UAF in August 2015. UAF operates the site under an agreement with the Air Force.
Pilots flying in the Gulkana area are asked to check with the Federal Aviation Administration for temporary flight restriction details.

Oncology researchers raise ethics concerns posed by patient-facing Artificial Intelligence
2023-11-03
BOSTON – Ready or not, patients with cancer are increasingly likely to find themselves interacting with artificial intelligence technologies to schedule appointments, monitor their health, learn about their disease and its treatment, find support, and more. In a new paper in JCO Oncology Practice, bioethics researchers at Dana-Farber Cancer Institute call on medical societies, government leaders, clinicians, and researchers to work together to ensure AI-driven healthcare preserves patient autonomy and respects human dignity.
The authors note that while AI has immense potential for expanding access to cancer care and improving the ...
New radiopharmaceutical shows antitumor activity in patients with advanced prostate cancer
2023-11-03
Researchers at Weill Cornell Medicine have led a phase 1 trial of a new drug that delivers potent radiation therapy directly and specifically to cancer cells in patients with advanced prostate cancer. The clinical trial showed that the “radiopharmaceutical” was well tolerated and demonstrated promising antitumor activity, according to a new study published on Nov. 2 in the Journal of Clinical Oncology.
The radiopharmaceutical 225AC-J591 was administered in a single injection and consists of two parts: an antibody that helps find the cancer cells is linked to a molecule that delivers a deadly dose of radiation. Specifically, an antibody named J591 that ...

MINNEAPOLIS/ST. PAUL (11/03/2023) — Research led by the University of Minnesota Medical School identified a new pathway to combat cardiovascular disease. The study was recently published in Nature Cardiovascular Research.
The research team’s work identifies a molecule called TREM2 as a unique and therapeutically relevant pathway for the treatment of atherosclerosis—a common condition that develops when plaque builds up inside arteries—in preclinical models. Atherosclerosis is a primary cause of cardiovascular diseases, which are the number one ...

Physicists ask: Can we make a particle collider more energy efficient?
2023-11-03
Ever since the discovery of the Higgs boson in 2012, physicists have wanted to build new particle colliders to better understand the properties of that elusive particle and probe elementary particle physics at ever-higher energy scales.
The trick is, doing so takes energy – a lot of it. A typical collider takes hundreds of megawatts – the equivalent of tens of millions of modern lightbulbs – to operate. That's to say nothing of the energy it takes to build the devices, and it all adds ...
Study shows that smoking ‘stops’ cancer-fighting proteins, causing cancer and making it harder to treat
2023-11-03
November 3, TORONTO — Scientists at the Ontario Institute for Cancer Research (OICR) have uncovered one way tobacco smoking causes cancer and makes it harder to treat by undermining the body’s anti-cancer safeguards.
Their new study, published today in Science Advances, links tobacco smoking to harmful changes in DNA called ‘stop-gain mutations’ that tell the body to stop making certain proteins before they are fully formed.
They found that these stop-gain mutations were especially prevalent in genes known as ‘tumour-suppressors’, ...

Some benefits of exercise stem from the immune system
2023-11-03
The connection between exercise and inflammation has captivated the imagination of researchers ever since an early 20th-century study showed a spike of white cells in the blood of Boston marathon runners following the race.
Now, a new Harvard Medical School study published Nov. 3 in Science Immunology may offer a molecular explanation behind this century-old observation.
The study, done in mice, suggests that the beneficial effects of exercise may be driven, at least partly, by the immune system. It shows that muscle inflammation caused by exertion mobilizes inflammation-countering T cells, or Tregs, which enhance the muscles’ ability to use ...
