Moon’s Hidden Ridges Reveal Recent Tectonic Activity
“Since the Apollo era, we’ve known about the prevalence of lobate scarps throughout the lunar highlands, but this is the first time scientists have documented the widespread prevalence of similar features throughout the lunar mare,” said Dr. Cole Nypaver.
Does our Moon exhibit recent tectonic activity? This is what a recent study published in The Planetary Science Journal hopes to address as a team of scientists investigated the potential for our Moon to have exhibited recent tectonic activity despite its interior not being geologically active. This study has the potential to help scientists better understand the processes responsible for tectonic activity on planetary bodies and what this could mean for the formation and evolution of planets and moons throughout the cosmos.
For the study, the researchers created the first global map of small mare ridges (SMRs) on the Moon, which are small, narrow tectonic ridges located within the lava plains on the Moon and are similar to lobate scarps, another frequently observed geologic formation on the Moon. They have been hypothesized to result from the Moon shrinking as it’s cooled over billions of years, with the top crust bucking under the pressure of compression.
Using a combination of lunar global mosaics and images from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Cameras (NACs), the researchers successfully identified and mapped more than 1,100 new SMRs across the nearside of the Moon. Through this, the researchers demonstrated these SMRs are geologically young compared to the surrounding regions and are widely distributed among the lunar volcanic plains.

Osteoradionecrosis After Radiotherapy for Oropharyngeal Carcinoma
Among patients with oropharyngeal squamous cell #carcinoma, proton therapy for head and neck cancer was associated with a higher 3-year incidence of osteoradionecrosis compared with intensity-modulated radiation therapy.
Severe osteoradionecrosis rates were low and did not differ by modality.
This cohort study characterizes the incidence, severity, and predictors of osteoradionecrosis in patients with oropharyngeal squamous cell carcinoma treated with curative-intent radiotherapy and compares outcomes between those receiving proton therapy vs intensity-modulated radiation therapy.
Blocking both drug-resistant bacteria and influenza with a broad-spectrum infection prevention approach
Secondary infections caused by bacteria or viruses during hospital care remain a long-standing global challenge, despite advances in modern medicine. In particular, mixed bacterial-viral infections in critically ill or immunocompromised patients are extremely difficult to treat and are associated with significantly increased mortality.
At the same time, the rapid rise of antibiotic-resistant bacteria and the frequent emergence of viral variants have exposed the limitations of existing antibiotics and vaccines. These challenges have driven growing interest in new strategies that prepare the body’s immune system in advance, enabling it to respond more rapidly and effectively when infection occurs.
Unlike conventional approaches that directly target specific pathogens, this emerging strategy focuses on priming the immune system so that immune cells can react faster and more strongly at the moment of infection.
Senescent astrocytes discovered in Alzheimer’s brains point to new treatment targets
Researchers from the NeuroAD group (Neuropathology of Alzheimer’s Disease) within the Department of Cell Biology, Genetics and Physiology at the University of Málaga, also affiliated with IBIMA–BIONAND Platform and CIBERNED, have made a pioneering breakthrough in the fight against this disease by identifying astrocytes as a promising cellular target for the development of future therapies.
The study demonstrates, for the first time, the presence of senescent astrocytes—cells that remain alive but have lost their functional capacity—in the brains of Alzheimer’s patients, positioning this cellular aging process as a key mechanism in neurodegeneration.
The research, published in the journal Journal of Neuroinflammation, was led by Dr. Antonia Gutiérrez, Professor of Cell Biology and Principal Investigator of the NeuroAD group, together with Dr. Juan Antonio García León, Associate Professor of Cell Biology. Other contributors to the study include Laura Cáceres, Laura Trujillo, Elba López, Elisabeth Sánchez, and Inés Moreno.
Env-antibody coevolution identifies B cell priming as the principal bottleneck to HIV V2 apex broadly neutralizing antibody development
Two new animal studies show that B cell priming is key to induce broadly neutralizing antibodies (bNAbs) against HIV and demonstrate that a single immunization that targets bNAb precursors can induce potent neutralization. Learn more in Science Immunology:
B cell priming is a primary bottleneck to HIV-1 V2 apex bNAb elicitation.
Can personality change after 60? An eight-week program suggests it can
Younger and older adults alike are able to adopt new socio-emotional behaviors. Even older adults benefit from a personality intervention aimed at handling stress and challenging social situations better. This is the conclusion of a psychological aging research study conducted by researchers from Germany and Switzerland led by Prof. Dr. Cornelia Wrzus (Heidelberg University) and Prof. Dr. Corina Aguilar-Raab (University of Mannheim). The study examined the effects of an intervention program in participants of varying ages. It concluded that social and emotional skills training benefits both younger and older adults.
The study is published in the journal Communications Psychology.
According to the scientific community, socio-emotional behaviors include a person’s ability to recognize, express, and regulate their feelings as well as social relationships. This ability is associated with personal traits that influence, for example, how a person typically thinks, feels, and behaves in certain situations.
