The final satellite in NOAA's GOES-R weather satellite series has a new place in orbit … and a new name.
The GOES-19 weather satellite, which launched into orbit in June 2024, has officially taken the place of its predecessor GOES-16 to watch over the Western Hemisphere from its perch 22,236 miles (35,785 kilometers) above us. To mark the milestone, the satellite has the new name of GOES East to serve as the dominant geostationary satellite in the fleet, NOAA officials said in a statement.
"With GOES-19 now in operation, NOAA has delivered the full fleet of GOES-R satellites to orbit, providing the most sophisticated technology ever flown in space to help forecast weather on Earth," said Stephen Volz, assistant administrator for NOAA's Satellite and Information Service, in the statement. "GOES-19 supports NOAA's mission to provide secure and timely access to global environmental data and information to promote and protect the nation's security, environment, economy and quality of life."
As GOES East, the satellite will be responsible for keeping a watchful eye on tropical development in the Atlantic Ocean, and monitor weather such as severe storms, wildfires, and atmospheric rivers. Just like its siblings, GOES-19 is equipped with technology to produce high-resolution imagery, take measurements of the atmosphere, and track the location and intensity of lightning in real-time.
If that's not exciting enough for scientists, this satellite also hosts NOAA's first compact coronagraph instrument (CCOR-1), monitoring the sun's activity.
"CCOR-1 is a game-changer for ensuring our nation is resilient to solar storms, monitoring massive eruptions of energy from the sun in real time," Clinton Wallace, director of NOAA's Space Weather Prediction Center, said in the statement. "With dramatically improved resolution and faster detection, it helps us better predict dangerous space weather that can impact satellites, GPS, astronaut safety, aviation and power grids, ensuring we can protect critical technology and infrastructure like never before."

Upgraded Northern Lights Alert: 14 States May See Aurora This Weekend

The aurora borealis or northern lights in the night sky over Shiprock, New Mexico. Days after the Northern Lights were glimpsed from northern U.S states — including Idaho, New Hampshire, Michigan and even Massachusetts — displays may be visible once again on Saturday night (July 26-27), according to a forecast by the National Oceanic and Atmospheric Administration's Space Weather Prediction Center. Although astronomical darkness is in short supply at northerly latitudes, sky-watchers in 14 U.S. states may have a chance to see the aurora borealis on the northern horizon during the night into Sunday morning. Northern Lights Tonight: Latest Forecast The agency's new three-day forecast indicates a minor geomagnetic storm, measured at a value of up to G1 on a scale of G1 to G5. According to NOAA's forecast, the Kp index — which provides a rough guide to the intensity of aurora displays — may reach 5 around 09:00-12:00 UTC (4:00 a.m. through 7:00 a.m. EDT). However, there is also a possibility that the geomagnetic storm could be a stronger G2 event. In a discussion post, NOAA officials stated that a G1 (Minor) geomagnetic storm is likely on July 27 'with a chance for isolated G2 (Moderate) periods due to CME effects from an event that left the Sun on 23 July.' According to the cause is a coronal mass ejection — a clump of charged particles ejected by the sun on July 23 — which is expected to interact with Earth's atmosphere. NASA's WSA-Enlil model has the CME striking Earth. Northern Lights Tonight: Where Aurora May Be Visible Keep an eye on NOAA's latest aurora viewline for an indication of exactly where aurora displays will potentially be seen from, but it will likely include parts of 14 northern U.S. states, and Canada, on July 26/27. U.S. states that may see aurora include (northerly parts of) Washington, northern Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Iowa, New York, Vermont, New Hampshire and Maine. Areas far from light pollution are likely to offer the best views. Check NOAA's 30-minute forecast or use the Glendale App for the latest forecasts and real-time information on substorms. Northern Lights Tonight: Why Aurora Are Being Seen So Far South The aurora borealis is being seen at more southerly latitudes than usual due to an increase in solar activity. Magnetic activity on the sun is currently at a 23-year high because it's reached solar maximum — the height of our star's 11-year solar cycle. Having possibly peaked in late 2024, the sun may now be quietening down, but solar maximum periods often have double peaks. It's also known that some of the best aurora displays can happen in the two years post-solar maximum. Decent aurora sightings in the U.S. are thus expected through 2026 and 2027. Northern Lights Tonight: Best Places And Times To See The Aurora The best places to see the Northern Lights are those at about 65 degrees north latitude between September and March (when there is sufficient hours of darkness). This is where the auroral oval sits, making northern Norway, northern Sweden, northern Finland, Iceland, Alaska and northern Canada reliable places for aurora sightings when skies are clear. Northern Lights Tonight: Aurora Explained The Northern Lights are caused by disturbances in Earth's magnetic field created by the solar wind. As charged particles accelerate along the magnetic field lines toward the polar regions, they collide with oxygen and nitrogen atoms, exciting them. That causes a photon of light to be released. Wishing you clear skies and wide eyes.

Gilead Receives Positive CHMP Opinions Under Accelerated Review From European Medicines Agency for Twice-Yearly Lenacapavir for HIV Prevention

FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion under accelerated review recommending lenacapavir—the company's injectable HIV-1 capsid inhibitor—for use as pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 in adults and adolescents with increased HIV-1 acquisition risk. The final European Commission (EC) decision is expected later this year, and, if approved, lenacapavir will be marketed in the European Union (EU) under the trade name Yeytuo ®. The marketing authorization application (MAA) recommendation will now be reviewed by the EC as it evaluates lenacapavir as a potential new preventative strategy against HIV in all 27 EU Member States, as well as Norway, Iceland and Liechtenstein. Additionally, if approved, lenacapavir will be granted one additional year of market exclusivity in the EU as a result of the new indication. The CHMP also adopted a positive EU-Medicines for all (EU-M4all) opinion, which enables a streamlined assessment for World Health Organization (WHO) prequalification and will facilitate national regulatory evaluations in low- and lower-middle-income countries (LLMICs). 'This milestone reflects our commitment to reimagine HIV prevention in Europe and around the world,' said Dietmar Berger, MD, PhD, Chief Medical Officer at Gilead Sciences. 'Lenacapavir for PrEP has the potential to become a critical tool for public health, helping to expand prevention options for people who face the highest barriers to care.' Despite ongoing advances in HIV prevention, persistent social and economic factors including stigma and discrimination continue to cause disparities in PrEP use. In 2023, a total of 24,731 new HIV diagnoses were reported across 30 EU/European Economic Area countries—an increase of 11.8% compared with 2022. 'These positive opinions from the CHMP are an important step toward a new HIV prevention option that could help meet the diverse needs of people across Europe and aim at helping end new HIV infections by the EU target of 2030,' said Jean-Michel Molina, MD, PhD, Université Paris Cité, Professor of Infectious Diseases and Head of the Infectious Diseases Department at the Saint-Louis and Lariboisière Hospitals. 'The opinions reflect the strength of the clinical evidence and the potential of long-acting innovations like lenacapavir to address real-world barriers to the use of PrEP. Expanding the range of PrEP options, in Europe and in countries around the world, is essential to making HIV prevention more accessible for people who need it most.' The positive opinions were supported by data from the Phase 3 PURPOSE 1 and PURPOSE 2 trials conducted by Gilead. In the PURPOSE 1 trial (NCT04994509), data at the primary analysis showed that administration of twice-yearly subcutaneous lenacapavir led to zero HIV infections among 2,134 participants, 100% reduction in HIV infections and superiority of prevention of HIV infections when compared with once-daily oral Truvada ® (emtricitabine 200mg and tenofovir disoproxil fumarate 300mg; F/TDF) in cisgender women in sub-Saharan Africa. In the PURPOSE 2 trial (NCT04925752), there were two HIV infections among 2,179 participants in the twice-yearly subcutaneous lenacapavir group, demonstrating 99.9% of participants did not acquire HIV infection and superiority of prevention of HIV infections when compared with once-daily oral Truvada among a broad and geographically diverse range of cisgender men and gender-diverse people. In both trials, lenacapavir demonstrated superiority of prevention of HIV infections when compared with background HIV incidence (bHIV) and was generally well-tolerated, with no significant or new safety concerns identified. Data from both trials were published in The New England Journal of Medicine and, based in part on the trial results, in December 2024 the journal Science named lenacapavir its 2024 'Breakthrough of the Year.' Continued Global Regulatory Filings for Lenacapavir for HIV Prevention, Milestone Partnerships and Global Guidance Gilead is executing a global access strategy informed by health advocates and organizations that prioritizes speed and enables the most efficient paths for regulatory review, approval of and access to twice-yearly lenacapavir for PrEP. More information about Gilead's recently announced strategic partnership agreement with The Global Fund to Fight AIDS, Tuberculosis and Malaria, as well as updates on Gilead's access strategies in countries and regions around the world: See Gilead press release More information about the WHO's recently announced guidelines for the use of lenacapavir for PrEP: See Gilead company statement Lenacapavir for PrEP is not approved by any regulatory authority outside of the United States. There is currently no cure for HIV or AIDS. About the PURPOSE Program Gilead's landmark PURPOSE program is the most comprehensive and diverse HIV prevention trial program ever conducted. The program comprises five HIV prevention trials around the world that are focused on innovation in science, trial design, community engagement and health equity. The PURPOSE trials are evaluating the safety and efficacy of an investigational, twice-yearly injectable medicine, lenacapavir, to reduce the chance of getting HIV. The Phase 2 and 3 program, consisting of PURPOSE 1-5, is assessing the potential of lenacapavir to help a diverse range of people around the world who could benefit from PrEP. More information about the PURPOSE program, including individual trial descriptions, populations and locations, can be found at About Lenacapavir Lenacapavir is approved in multiple countries for the treatment of multi-drug-resistant HIV in adults, in combination with other antiretrovirals. Lenacapavir is also approved in the United States to reduce the risk of sexually acquired HIV in adults and adolescents (≥35kg) who are at risk of HIV acquisition. The multi-stage mechanism of action of lenacapavir is distinguishable from other currently approved classes of antiviral agents. While most antivirals act on just one stage of viral replication, lenacapavir is designed to inhibit HIV at multiple stages of its lifecycle and has no known cross resistance exhibited in vitro to other existing drug classes. Lenacapavir is being evaluated as a long-acting option in multiple ongoing and planned early and late-stage clinical studies in Gilead's HIV prevention and treatment research program. Lenacapavir is being developed as a foundation for potential future HIV therapies with the goal of offering both long-acting oral and injectable options with several dosing frequencies, in combination or as a mono agent, that help address individual needs and preferences of people and communities affected by HIV. The journal Science named lenacapavir its 2024 'Breakthrough of the Year.' U.S. Indication for Yeztugo ® Yeztugo (lenacapavir) injection, 463.5 mg/1.5 mL, is indicated for pre‑exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 in adults and adolescents (≥35kg) who are at risk for HIV-1 acquisition. Individuals must have a negative HIV-1 test prior to initiating Yeztugo. U.S. Important Safety Information for Yeztugo BOXED WARNING: RISK OF DRUG RESISTANCE WITH USE OF YEZTUGO IN UNDIAGNOSED HIV-1 INFECTION Individuals must be tested for HIV-1 infection prior to initiating Yeztugo, and with each subsequent injection of Yeztugo, using a test approved or cleared by the FDA for the diagnosis of acute or primary HIV-1 infection. Drug-resistant HIV-1 variants have been identified with use of Yeztugo by individuals with undiagnosed HIV-1 infection. Do not initiate Yeztugo unless negative infection status is confirmed. Individuals who acquire HIV-1 while receiving Yeztugo must transition to a complete HIV-1 treatment regimen. Contraindications Yeztugo is contraindicated in individuals with unknown or positive HIV-1 status. Warnings and precautions Comprehensive risk management: Use Yeztugo to reduce the risk of HIV-1 acquisition as part of a comprehensive prevention strategy including adherence to the administration schedule and safer sex practices, including condoms, to reduce the risk of sexually transmitted infections (STIs). HIV-1 acquisition risk includes behavioral, biological, or epidemiologic factors including, but not limited to, condomless sex, past or present STIs, self-identified HIV risk, having sexual partners of unknown HIV-1 viremic status, or sexual activity in a high-prevalence area or network. Counsel individuals on the use of other prevention methods to help reduce their risk. Use Yeztugo only in individuals confirmed to be HIV-1 negative. Evaluate for current or recent signs or symptoms consistent with HIV-1 infection. Confirm HIV-1 negative status prior to initiating, prior to each subsequent injection, and as clinically appropriate. Potential risk of resistance: There is a potential risk of developing resistance to Yeztugo if an individual acquires HIV-1 before or when receiving Yeztugo, or following discontinuation. HIV- 1 resistance substitutions may emerge in individuals with undiagnosed HIV-1 infection taking only Yeztugo, because Yeztugo alone is not a complete regimen for HIV-1 treatment. To minimize this risk, it is essential to test before each injection and additionally as clinically appropriate. Individuals confirmed to have HIV-1 must immediately begin a complete HIV-1 treatment regimen. Alternative forms of PrEP should be considered after discontinuation of Yeztugo for those who are at continuing risk of HIV-1 acquisition and should be initiated within 28 weeks of the last Yeztugo injection. Long-acting properties and potential associated risks: Residual concentrations of Yeztugo may remain in systemic circulation for up to 12 months or longer after the last injection. Select individuals who agree to the required injection dosing schedule because nonadherence or missed doses could lead to HIV-1 acquisition and development of resistance. Serious injection site reactions: Improper administration (intradermal injection) has been associated with serious injection site reactions, including necrosis and ulcer. Only administer Yeztugo subcutaneously. Adverse reactions Most common adverse reactions (≥5%) in Yeztugo clinical trials were injection site reactions, headache, and nausea. Drug interactions Strong or moderate CYP3A inducers may significantly decrease Yeztugo concentrations. Dosage modifications are recommended when initiating these inducers. It is not recommended to use Yeztugo with combined P-gp, UGT1A1, and strong CYP3A inhibitors. Coadministration of Yeztugo with sensitive substrates of CYP3A or P-gp may increase their concentrations and result in the increased risk of their adverse events. Yeztugo may increase the exposure of drugs primarily metabolized by CYP3A initiated within 9 months after the last injection of Yeztugo. Dosage and administration HIV screening: Test for HIV-1 infection prior to initiating, prior to each subsequent injection, and as clinically appropriate using an approved or cleared test for the diagnosis of acute or primary HIV-1 infection. Dosage: Initiation dosing (injections and tablets) followed by once-every-6-months continuation injection dosing. Tablets may be taken with or without food. Initiation: Day 1: 927 mg by subcutaneous injection (2 x 1.5-mL injections) and 600 mg orally (2 x 300-mg tablets). Day 2: 600 mg orally. Continuation: 927 mg by subcutaneous injection every 6 months (26 weeks) from date of last injection ±2 weeks. Anticipated delayed injections: If scheduled 6-month injection is anticipated to be delayed by more than 2 weeks, Yeztugo tablets may be taken on an interim basis (for up to 6 months) until injections resume. Dosage is 300 mg orally (1 x 300-mg tablet) once every 7 days. Resume continuation injections within 7 days of the last oral dose. Missed injections: If more than 28 weeks have elapsed since the last injection and Yeztugo tablets have not been taken, restart with initiation dosing if clinically appropriate. Dosage modifications of Yeztugo are recommended when initiating with strong or moderate CYP3A inducers. Consult the full Prescribing Information for recommendations.

Weight-loss jabs could help obese people control asthma, study suggests

Weight-loss jabs could help minimise asthma symptoms in obese people, according to a study. The drugs should be explored as a potential treatment for obese people with the respiratory condition, who are 'often resistant' to steroids, researchers said. Weight-loss jabs, also known as glucagon-like peptide1 receptor-agonists (GLP1-RAs), work by mimicing the hormone GLP-1 to regulate blood sugar and insulin levels. They were initially developed as a treatment for people with type 2 diabetes. A number of types of the drug are recommended to help tackle obesity on the NHS, including semaglutide, or Wegovy, and tirzepatide, or Mounjaro. Previous studies have suggested the drugs may slash the risk of illnesses like dementia and stroke, with an international team of experts exploring their potential impact on obese people with asthma. Professor David Price, University of Aberdeen chair in primary care respiratory medicine, said: 'People with obesity and asthma are unique in that they are often resistant to steroid treatments. 'We know that GLP1s work on inflammatory responses in the airways in a different way to traditionally used steroids.' For the study, published in Advances in Therapy, researchers analysed the records of 10,111 people on GLP1-RAs and 50,555 people who were not on the drugs. After a follow-up period, the team found that those taking weight-loss jabs lost more weight and had improved asthma control. Researchers said the findings suggest medics 'should pay attention to the relationship between GLP-1 RA and the risk of respiratory diseases'. Prof Price added: 'We found compelling evidence that GLP1s, as well as increasing weight loss, also improved asthma symptoms. 'In addition, it is important to note that the benefits to asthma symptoms occurred despite fairly modest weight loss of around 0.9kg over the course of the year. 'Our findings suggest that GLP1s may have beneficial effects on asthma control for people with obesity and this should be explored further.' Prof Alan Kaplan, chairperson of the Family Physician Airways Group of Canada and the Observational and Pragmatic Research Institute, said: 'Our findings suggest that GLP1-RAs have benefits on asthma control in people with obesity, and this information should contribute to the discussions around the decision to use these drugs.' Dr Erika Kennington, head of research and innovation at Asthma and Lung UK, said: 'Research has previously shown that people living with obesity who lose weight see improved control of their asthma, so it's encouraging to see this study show this is still the case when the weight loss is driven by drugs, like the new class of weight loss drugs. 'Although exercise can help people lose weight, for some people it can cause anxiety about becoming breathless or having an asthma attack, so people are stuck in a vicious cycle of not being able to lose weight and their asthma worsening. 'Therefore, where exercise hasn't worked for someone these drugs that support weight loss could offer a promising alternative. 'It's too early to say whether these drugs would be effective for people with asthma more widely. 'More research is needed to understand how these drugs actually improve asthma control. Funding for lung health research is on life support and urgent action is needed to increase investment.'
