Scientists have discovered that Archaeopteryx, the famous link between birds and reptiles, did not give rise to modern birds. Instead, they appear to have descended from a different, unknown ancestor with many characteristics of modern birds. This discovery challenges the classic view of bird evolution.
Researchers at Georgia Institute of Technology developed a novel experimental technique called Thermoiré to track circuit board warpage in real-time. This allows manufacturers to make design changes before production, reducing losses and increasing product reliability.
A new laser technique called Scanning Lidar Imager of Canopies by Echo Recovery (SLICER) can rapidly assess forest canopy shapes, allowing for accurate predictions of carbon storage and tree characteristics. This technology has the potential to improve our understanding of forest management and global climate change.
Researchers localized the gene responsible for Parkinson's disease to a small region of chromosome 4, marking a significant advancement in understanding the disease. This finding is based on a large family study with multiple cases of Parkinson's disease over several generations.
The PowerDigm solid-state transfer switch is being installed at Ford Motor Co.'s Sheldon Road Plant to protect against costly power interruptions. The switch can sense disturbances in one power source and automatically switch to a different source, improving reliability and reducing outages.
Leptospirosis, a bacterial disease carried by rats, poses a significant risk to urban residents in the US. Studies have shown that up to 10% of infected individuals develop severe Weil's disease, which can be fatal.
Researchers identify a gene on chromosome 4 as a potential cause of Parkinson's disease, shedding light on the mysterious origins of this debilitating condition. The discovery may lead to genetic testing, early diagnosis, and treatment options for all forms of Parkinson's disease.
A new Weizmann Institute of Science study finds that high levels of leptin disrupt insulin's activities, leading to raised blood sugar levels. Researchers discovered that excessive leptin suppresses insulin's ability to slow down gluconeogenesis, a process that can cause diabetes-related symptoms.
Researchers at Harvard Medical School have visualized the first image of a membrane-spanning molecule thought to transport proteins across cell membranes. The study reveals a dynamic structure that appears and disappears on demand, with the channel opening in two dimensions for different protein types.
