(Press-News.org) An increasing number of space objects, debris, and satellites in Low Earth Orbit poses a significant threat of collisions during space operations. The situation is currently monitored by radar and radio-telescopes that track space objects, but much of space debris is composed of very small metallic objects that are difficult to detect. In a study published in IET Radar, Sonar & Navigation, investigators demonstrate the benefits of using deep learning—a form of artificial intelligence—for small space object detection by radar.
The team modelled a prominent radar system in Europe (called Tracking and Imaging Radar) in tracking mode to produce training and testing data. Then, the group compared classical detection systems with a You-Only-Look-Once (YOLO)–based detector. (YOLO is a popular object detection algorithm that has been widely used in computer vision applications.) An evaluation in a simulated environment demonstrated that YOLO-based detection outperforms conventional approaches, guaranteeing a high detection rate while keeping false alarm rates low.
“In addition to improving space surveillance capabilities, artificial intelligence–based systems like YOLO have the potential to revolutionize space debris management,” said co–corresponding author Federica Massimi, PhD, of Roma Tre University, in Italy. “By quickly identifying and tracking hard-to-detect objects, these systems enable proactive decision-making and intervention strategies to mitigate collisions and risks and preserve the integrity of critical space resources.”

How does a diabetes drug lessen symptoms of depression?
2024-03-06
Research in animals has shown that the diabetes drug dulaglutide, which is a glucagon-like peptide-1 (GLP-1) receptor agonist may reduce symptoms of depression. A new study published in Brain and Behavior reveals the mechanisms that are likely involved.
By conducting a range of tests in mice treated with and without dulaglutide, investigators confirmed the effects of dulaglutide on depressive-like behaviors, and they identified 64 different metabolites and four major pathways in the brain associated with these effects.
Markers of depression and the antidepressant effects of dulaglutide were linked to lipid metabolism, amino acid metabolism, energy metabolism, ...
How do artificial intelligence programs fare in dermatology applications for people with diverse skin tones?
2024-03-06
Artificial intelligence (AI) programs have recently acquired widespread popularity in dermatology for assessing, diagnosing, and treating skin conditions. As reported in the International Journal of Dermatology, investigators recently analyzed all published studies from the last 10 years to evaluate current AI programs in use for dermatologic purposes, uncovering significant shortcomings when applied to skin of color (SOC).
The researchers identified various challenges when this technology is applied to SOC, ...
Has Medicaid expansion affected pregnancy outcomes among women with gestational diabetes?
2024-03-06
The Affordable Care Act (ACA) aims to broaden healthcare access, but its effect on maternal and newborn health among women with gestational diabetes—or diabetes that develops during pregnancy—across diverse demographics is unclear. In a study published in the International Journal of Gynecology & Obstetrics, researchers compared the impact of the implementation of the ACA on maternal and newborn health in Maryland (with ACA implementation) and Georgia (without ACA implementation) among 52,479 women.
The investigators found that after ACA implementation, Maryland showed improved newborn outcomes compared ...
What are the trends and outcomes of anterior cruciate ligament injury treatments in children?
2024-03-06
Anterior cruciate ligament (ACL) injuries have increased in recent decades among children. Because re-injuries after ACL reconstruction are higher in children compared with adults, anterolateral augmentation procedures may reduce re-injury rates after ACL reconstruction in youth. A comprehensive review published in the Journal of Experimental Orthopaedics marks the first attempt to present the outcomes and surgical methods of anterolateral augmentation procedures for skeletally immature patients.
“We found many different surgical techniques ...
Gene discovered that can protect against severe muscle disease
2024-03-06
A specific gene may play a key role in new treatments that prevent muscle in the body from breaking down in serious muscle diseases, muscular dystrophies. This is shown in a new study at Umeå University, Sweden. Protein expressed by the gene naturally prevents the muscles around the eye from being affected when other muscles in the body are broken down during muscular dystrophies. In the study, the so-called genetic scissors were used and the gene is expressed in all muscles. The effects were that muscular dystrophin was alleviated throughout the body.
"You could say that the eye muscles function as both an eye-opener for understanding the disease and as a door ...
Communities of color across the US suffer a growing burden from polluted air
2024-03-06
WASHINGTON (March 6, 2024)--Despite progress toward cleaner air in the US, a new study suggests that communities of color across the nation are shouldering a growing burden of diseases linked to air pollution. A paper published today by researchers at the George Washington University suggests that racial and ethnic disparities in cases of pollutant-linked diseases like asthma increased during the last decade.
“Redlining and systemic racism have resulted in the least white areas of the US being located near factories, congested roadways or shipping routes with heavily ...
Can you tell AI-generated people from real ones?
2024-03-06
If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you're not alone.
A new study from University of Waterloo researchers found that people had more difficulty than was expected distinguishing who is a real person and who is artificially generated.
The Waterloo study saw 260 participants provided with 20 unlabeled pictures: 10 of which were of real people obtained from Google searches, and the other 10 generated by Stable Diffusion or DALL-E, two commonly used AI programs that generate ...
