(Press-News.org) August 26, 2024, Mountain View, CA -- The SETI Institute, the Berkeley SETI Research Center and the International Centre for Radio Astronomy Research announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia. Led by Dr. Chenoa Tremblay of the SETI Institute and Prof. Steven Tingay of Curtin University, this research is the first to search for signs of alien technology in galaxies beyond our own, focusing on low radio frequencies (100 MHz). This innovative study used the MWA’s large field of view (FOV), allowing the team to cover about 2,800 galaxies in one observation, of which 1300 we know the distance to. Usually, the search for extraterrestrial intelligence (SETI) has focused on signals within our galaxy. This new approach goes further, looking at distant galaxies. This new approach looks at distant galaxies, making it one of the most detailed searches for super civilizations—those more advanced than ours. To send a signal from another galaxy, a civilization would need technology powerful enough to use the energy of their sun or several stars in their galaxy.
“This work represents a significant step forward in our efforts to detect signals from advanced extraterrestrial civilizations,” said Tremblay. “The large field of view and low-frequency range of the MWA makes it an ideal tool for this kind of re- search, and the limits we set will guide future studies.”
While this first study did not find any technosignatures (signs of alien technology), it provides insights that will help focus future searches. It shows how important it is to keep exploring different radio frequencies and using the unique capabilities of telescopes like the MWA.
“The MWA continues to open up new ways of exploring the Universe for intelligent civilizations and technosig- natures, while using the same data to study the astrophysics of stars and galaxies. This work is new and novel, but also paves the way for future observations with even more powerful telescopes,” said Tingay, who is also the Director of the MWA.
This research highlights the importance of working together internationally and using advanced technology to expand our understanding of the Universe. The SETI Institute explores the cosmos for signs of intelligent life and works to increase our knowledge of the universe.

Bicycle rolling-stop laws don’t lead to unsafe behavior by riders or motorists, research shows
2024-08-26
CORVALLIS, Ore. – Laws that let bicyclists treat stop signs as yield signs lead neither riders nor motorists to act unsafely, according to a groundbreaking Oregon State University study.
The project by OSU College of Engineering researchers featured a novel experimental technique – linking separate bicycle and motor vehicle simulators – and the findings are important as more and more states consider bicycle rolling-stop legislation, said David Hurwitz, the study’s leader.
“It required fully connecting two independent simulators, running subjects in pairs simultaneously and having each subject interacting with an avatar of the other in a shared virtual ...
How a retracted paper affected the course of Alzheimer’s research (video)
2024-08-26
WASHINGTON, Aug. 26, 2024 — In June 2024, a landmark Alzheimer's research paper was retracted due to fraud allegations. Did we waste billions of dollars and thousands of hours of scientists’ time? Maybe not. There are now two potentially helpful drugs on the market targeting the subject of the paper: amyloid beta. This video breaks down the amyloid-beta hypothesis, the fraud itself and where we go from here.

Genotype Matters: Tailored screening for germline CHEK2 variants
2024-08-26
“In our study, we postulated that these differences were driven by three common low-risk (LR) missense variants: p.I157T, p.S428F, and p.T476M, all of which have a BC odds ratio of <1.4.”
BUFFALO, NY- August 26, 2024 – A new editorial was published in Oncotarget's Volume 15 on July 10, 2024, entitled, “Genotype matters: Personalized screening recommendations for germline CHEK2 variants.”
Recognized as a moderate-risk gene, CHEK2—responsible for encoding the CHK2 protein, ...
Interlimb and intralimb synergy modeling for lower limb assistive devices: Modeling methods and feature selection
2024-08-26
A research paper by scientists at Hainan University proposed FSS-eq2Seq as a 2-stage strategy for gait synergy modeling in lower limb assistive devices to achieve synergic and user-adaptive trajectories that improve human-machine interactions.
The new research paper, published on Jul. 03 in the journal Cyborg and Bionic Systems, indicatedSeq2Seq outperforms LSTM, RNN, and GRU in both interlimb and intralimb synergy modeling. Further, FS significantly improves Seq2Seq’s modeling performance.
The concept of gait synergy provides novel human-machine interfaces and has been applied ...
Darwin’s fear was unjustified: Writing evolutionary history by bridging the gaps
2024-08-26
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil record has gaps and is incomplete, and we’re missing data that we need to reconstruct evolutionary history. Now, a team of sedimentologists and stratigraphers from the Netherlands and the UK examined how this incompleteness influences the reconstruction of evolutionary history. To their surprise, they found that the incompleteness itself is actually not such a big issue. “It’s ...
Trends of heat-related deaths in the US, 1999-2023
2024-08-26
About The Study: This study found that heat-related mortality rates in the U.S. increased between 1999 and 2023, especially during the last 7 years. Although a study using data through 2018 found a downward trend in heat-related mortality in the U.S., this study is the first to our knowledge to demonstrate a reversal of this trend from 2016 to 2023. These results align with site-specific data analyzed in a global study that suggest increases in heat-related mortality. As temperatures continue to rise because of climate change, the recent increasing trend is likely to continue. Local authorities in high-risk areas should consider investing in the expansion of access to hydration centers ...
Transgender students more likely than cisgender peers to seek support from school staff, UW–Madison and NYU study finds
2024-08-26
MADISON – Transgender students are more likely to seek support from school staff and less likely to seek support from their parents when compared to their cisgender peers, according to a new study from researchers at the University of Wisconsin–Madison and New York University.
The study, published in JAMA Pediatrics, found among students who felt depressed or anxious, transgender students were 74% less likely than their cisgender peers to seek help from parents than from adults in schools. It also found transgender students were 25% less likely than cisgender students to seek support from ...
Longitudinal changes in youth mental health from before to during the COVID-19 pandemic
2024-08-26
About The Study: In this longitudinal cohort study of economically and racially diverse U.S. youth, there was evidence of differential susceptibility and resilience for mental health problems during the pandemic that was associated with prepandemic mental health and sociodemographic characteristics. These differences are critical to understand for recovery and may yield novel insights into causes of youth mental health problems.

Repetitive head impacts and perivascular space volume in former football players
2024-08-26
About The Study: In this cross-sectional cohort study of 170 former football players and 54 unexposed controls, larger perivascular space (PVS) volume was associated with greater exposure to repetitive head impacts (RHI). Additionally, PVS volume was associated with worse performance on cognitive tests. These findings suggest that PVS volume may contribute to the association between exposure to RHI, cognitive impairment, and the development of RHI-associated neurodegeneration.

Sharing expands caring – UMD study finds solution to a major source of doctor burnout
2024-08-26
COLLEGE PARK, Md. – Who hasn’t sat in a medical office, listening to computer keys clacking while their provider rapidly types up notes, wondering what they are spending so much time writing about? For doctors, who have always written clinical care notes but increasingly must spend time cataloging billing details, this additional documentation is a major source of job dissatisfaction and burnout. A new study out today by University of Maryland’s School of Public Health illuminates a solution that can meaningfully reduce the amount of time doctors spend writing notes, without losing vital information.
