With the continuous advancement of spaceborne synthetic aperture radar (SAR) technology, L-band SAR has come to play an increasingly important role in Earth observation; however, its imaging, interferometric, and polarimetric performance are susceptible to ionospheric disturbances. In equatorial nighttime data, amplitude streak artifacts induced by equatorial plasma bubbles frequently occur and have traditionally been regarded as interference factors in SAR imaging. Nevertheless, these artifacts essentially carry critical information on ionospheric irregularities and can be exploited to retrieve physical parameters such as scintillation intensity and turbulence spectral indices. Existing methods either rely on comparisons between disturbed and undisturbed images or are limited to preliminary one-dimensional parameter estimation along the track, making it difficult to achieve two-dimensional fine-scale retrieval of scintillation structures, and lacking systematic validation of their spatial correlation with equatorial ionospheric anomalies. Therefore, how to extract the two-dimensional spatial distribution of ionospheric scintillation parameters from amplitude streak artifacts and reveal their intrinsic relationship with regions of enhanced electron density has become an important scientific question in the field of ionospheric remote sensing.

A small, nest-dwelling tick found across large parts of Texas could play an outsized role in how the United States responds to African swine fever (ASF) should the virus reach domestic or wild pigs.

In a recent study, researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS), Texas A&M AgriLife Research and the Department of Biology mapped where Ornithodoros turicata — a soft tick species native to Texas and the southwestern United States — is most likely to survive and examined what that means for ASF preparedness.

The study is part of a $1.4 million Department of Homeland Security-funded research project through the Cross-Border Threat Screening and Supply Chain Defense (CBTS), DHS Science and Technology Directorate (S&T) Center of Excellence housed at Texas A&M. Led by Dr. Meriam Saleh, a clinical assistant professor in VMBS’ Department of Veterinary Pathobiology, this project seeks to understand whether Texas-derived populations of the tick could help sustain or transmit the virus if it were introduced into the U.S. — and how that risk could affect the food supply, trade and cross-border livestock movement. By supporting research at the intersection of animal health, border security and supply chain resilience, CBTS helps address emerging transboundary threats before they escalate into large-scale economic or homeland security challenges.

Fatigue is physical and mental exhaustion that can often be an early sign of severe health conditions. Current treatments for fatigue are mostly behavioral, including light physical activity, improved diet, stress reduction, and rest. Researchers are studying additional ways to manage fatigue, including supplements and enriched foods.

A research team set out to discover how the apparent temperature, or “feels like” temperature, over the ocean differs from the apparent temperature on land and found that a pronounced land-sea contrast is evident.

Researchers at the University of Science and Technology of China have developed an ultra-thin spray cooling heat sink only 3.5 mm thick and experimentally demonstrated its performance on a silicon-based thermal test chip. The study was published in Thermo-X.
