Course correction keeps Parker Solar Probe on track for Venus flyby

Course correction keeps Parker Solar Probe on track for Venus flyby
2023-08-10
(Press-News.org) NASA’s Parker Solar Probe executed a short maneuver on Aug. 3, 2023, that kept the spacecraft on track to hit the aim point for the mission’s sixth Venus flyby on Monday, Aug. 21, 2023. ​

Operating on preprogrammed commands from mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, Parker fired its small thrusters for 4.5 seconds, enough to adjust its trajectory by 77 miles and speed up – by 1.4 seconds – its closest approach to Venus. The precise timing and position are critical to that flyby, the sixth of seven approaches in which Parker uses the planet’s gravity to tighten its orbit around the Sun.

“Parker’s velocity is about 8.7 miles per second, so in terms of changing the spacecraft’s speed and direction, this trajectory correction maneuver may seem insignificant,” said Yanping Guo, mission design and navigation manager at APL. “However, the maneuver is critical to get us the desired gravity assist at Venus, which will significantly change Parker’s speed and distance to the Sun”.

Parker Solar Probe will be moving 394,742 miles per hour when it comes within just 4.5 million miles from the Sun’s surface – breaking its own record for speed and solar distance – on Sept. 27, 2023. Follow the spacecraft’s journey through the inner solar system on the Parker Solar Probe website.

Computer-aided cell analysis for faster diagnosis of blood diseases

2023-08-10
Scientists from the German Cancer Research Center (DKFZ) and the Cambridge Stem Cell Institute have developed an AI system that recognizes and characterizes white and red blood cells in microscopic images of blood samples. The algorithm can help physicians diagnose blood disorders and is available as an open source method for research purposes. Blood disorders are often characterized by altered numbers and aberrant shapes of red and white blood cells. To diagnose the diseases, physicians classically examine blood smears on a slide under a microscope. This type of diagnosis is straightforward, but evaluation by experienced experts is difficult because the changes are sometimes ...

National QIS Research Centers to host virtual career fair

National QIS Research Centers to host virtual career fair
2023-08-10
UPTON, NY– Registration is now open for the third Quantum Information Science Career Fair hosted by the U.S. Department of Energy (DOE) Office of Science’s National Quantum Information Science (QIS) Research Centers. The virtual event takes place on Wednesday, Sept. 13. The event aims to make undergraduates, graduate students, postdocs and early-career professionals aware of the wide range of QIS careers they can pursue—including technical and scientific roles as well as positions that facilitate research and bring awareness to the field, such as ...

Enhanced gut microbiome diversity linked to improved survival in children receiving stem cell transplants

2023-08-10
(WASHINGTON, August 10, 2023) – Researchers in Italy have shown for the first time that among children who have undergone a donor stem cell transplant, the presence of diverse species of micro-organisms in the intestinal tract before the transplant resulted in significantly better overall patient survival and fewer complications. The study, published today in the journal Blood, adds to a growing body of research unraveling the role gut health plays in health outcomes. “Our study provides the first evidence of a relationship between pre-transplant microbial diversity in the intestinal tract and post-transplant ...

SwRI micropatch algorithm improves ground-to-spacecraft software update efficiency

SwRI micropatch algorithm improves ground-to-spacecraft software update efficiency
2023-08-10
San Antonio – August 10, 2023 – Southwest Research Institute developed an algorithm to remotely update and repair spacecraft software using less time and data than conventional techniques. The tool not only improves the overall efficiency of satellite software transmissions but also can recover data from failed over-the-air updates and malicious cyberattacks. It works by identifying missing bytes and other errors before deploying a custom “micropatch” to the damaged or missing software. “Instead of updating an entire file or operating system, which is typically required with over-the-air satellite software updates, our ...

Study ties fracking to another type of shaking

Study ties fracking to another type of shaking
2023-08-10
New research confirms fracking causes slow, small earthquakes or tremors, whose origin was previously a mystery to scientists. The tremors are produced by the same processes that could create large, damaging earthquakes.  Fracking is the high-pressure injection of fluids underground to extract oil and natural gas. Though it is typically done with wastewater, this study examined data from fracking with liquid carbon dioxide. The process pushes carbon underground and keeps it from trapping heat in Earth’s atmosphere. By some estimates, carbon dioxide fracking could save as much ...

Good Clinical Trials Collaborative and leading clinical trial networks join forces to improve clinical research in low resource settings

2023-08-10
London, United Kingdom, 10 August 2023 – Four major clinical trial networks based in low resource settings are embarking on an exciting partnership with the Good Clinical Trials Collaborative (“GCTC”) to enhance clinical research in low resource settings. By promoting the unique qualities of randomized controlled trials (RCTs) and the evidence they produce, the collaboration aims to support regional research ecosystems to prioritize collaborative, informative and efficient research responses to public health challenges. ADVANcing Clinical Evidence in Infectious Diseases (“ADVANCE-ID”), Africa ...

Gastrointestinal viruses all but disappeared during COVID—but surged back two years on

2023-08-10
Washington, D.C. –  Following the first stay-at-home orders issued in the U.S. to curb the spread of COVID-19, gastrointestinal viruses such as norovirus, rotavirus and adenovirus all but disappeared from California communities, and remained at very low levels for nearly 2 years. The research is published in the Journal of Clinical Microbiology, a journal of the American Society for Microbiology. Interestingly, these viruses surged back to pre-pandemic levels in late 2022, said Niaz Banaei, M.D., professor of Pathology and Medicine (Infectious Diseases), Stanford University, and Medical Director of Clinical Microbiology Laboratory, Stanford Health Care. “Adenovirus ...

Measuring communication experiences of families of inpatients unable to make decisions for themselves

2023-08-10
INDIANAPOLIS – As the population of the United States grows older, more and more family members will be called upon to make medical decisions during hospitalizations of those who cannot make decisions for themselves. Good quality, focused, empathetic and timely communication between family members and clinicians is essential for good decision-making. Researcher-clinicians from Regenstrief Institute and Indiana University School of Medicine developed the 30-question Family Inpatient Communication Survey (FICS) to measure the experience of communication with hospital staff from the perspective of family members of seriously ill patients unable ...

Research details perils of not being attractive or athletic in middle school

Research details perils of not being attractive or athletic in middle school
2023-08-10
Despite the many changes in school culture since the 1960s, a new study reveals that some things never change: life is harder for middle school students who are not attractive and for those who are not athletic.  As children head back to school, the first-of-its-kind longitudinal study by Florida Atlantic University helps to explain why adolescents who lack traits valued by peers are at risk for adjustment difficulties. Results, published in the Journal of Youth and Adolescence, show that low attractive ...

Gut microbiota and immune alteration in cancer development: implication for immunotherapy

Gut microbiota and immune alteration in cancer development: implication for immunotherapy
2023-08-10
A vast number of microbes colonizes the human body to form an ecological community known as the microbiota. Microbiota are made up of bacteria, viruses, fungi, and archaea. These microbes are closely associated with the physiology and function of the human body. The gut microbiota has received tremendous research attention with the recent advance in metagenomic sequencing.  Under normal conditions, the gut microbiota is maintained in homeostasis, yet it is readily affected by various environmental factors, including diet and use of ...
