Led by a team of Duke Health neuroscientists, the study appears Aug. 30 in the journal Science Translational Medicine.   “Currently, Parkinson’s disease is diagnosed largely based on clinical symptoms after significant neurological damage has ...

The surface protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), known as the spike protein, is critical for infecting host cells. The spike protein facilitates the infection process by binding to angiotensin-converting enzyme 2 (ACE2) receptors on the surface of airway epithelial cells, initiating the virus entry into the cells. By engineering an ACE2 receptor to increase the affinity to the spike protein, researchers demonstrated a novel method to neutralize the virus effectively. The engineered ACE2 (3N39v4-Fc) acts as a decoy by binding to the viral spike protein, thus preventing the binding of viruses to the ACE2 receptor on the cell surface. ...

New Curtin research into injuries sustained by trail users has found mountain biking is not the dangerous, injury-plagued sport reserved for thrill-seekers that it is often perceived to be and that the health benefits outweigh the risks. Researchers analysed data from dozens of studies across the world, including Australia, encompassing 220,935 injured mountain bikers and 17,757 injured hikers. The study aimed to pinpoint the injury types and affected body areas in order to gain insights into the medical treatment of such cases.

The same neurons that help bats navigate through space may also help them navigate collective social environments, finds a new study published today in the journal Nature. Many mammals — including bats and humans — are believed to navigate with the help of a brain structure called the hippocampus, which encodes a mental “map” of familiar surroundings. For example, as you walk around your neighborhood or commute to work, individual “place” neurons in the hippocampus fire to indicate where you are. In the new study, researchers at the University of California, Berkeley, used wireless neural ...

  AURORA, Colo. (Aug. 30, 2023) – Scientists at the University of Colorado Anschutz Medical Campus have made a `paradigm shifting’ discovery on the mechanisms required for learning and memory that could lead to new therapies for Alzheimer’s disease and potentially Down syndrome. The study was published Wednesday in the journal Nature. For over 30 years, researchers believed that LTP or long-term potentiation, which is crucial for learning and memory, required enzymatic actions by an enzyme known as CaMKII. But a team of researchers led by Ulli ...

Modern medicine depends on antibiotics to treat infections by disabling targets inside bacterial cells. Once inside these cells, antibiotics bind to certain sites on specific enzyme targets to stop bacterial growth. Randomly occurring changes (mutations) in the genes for these targets occur naturally, in some cases making the target harder for the antibiotic to attach to, and that bacterial version resistant to treatment. For this reason, the more antibiotics have been used over time, the greater the chances that bacterial populations will evolve to have mutants resistant to existing antibiotics, and the more urgent the call for new approaches ...

Coastal wetlands and coral reef islands will struggle to grow fast enough to keep pace with rising sea levels driven by climate change, according to a new study published in Nature. The study was conducted by an international team that includes a Tulane University researcher. The findings show that the future of marshes and other low-lying coastal areas depend heavily on whether global warming can be limited to less than 2 degrees Celsius (3.6 degrees Fahrenheit) as formulated by the Paris Agreement. A key finding of the paper is that coastal marshes, mangroves, ...

Researchers have a new way to connect quantum devices over long distances, a necessary step toward allowing the technology to play a role in future communications systems. While today’s classical data signals can get amplified across a city or an ocean, quantum signals cannot. They must be repeated in intervals — that is, stopped, copied and passed on by specialized machines called quantum repeaters. Many experts believe these quantum repeaters will play a key role in future communication networks, allowing enhanced security and enabling connections between remote quantum computers. The Princeton study, published Aug. ...

Cardiovascular disease remains the leading cause of racial disparities in mortality between Black and white people in the United States. New research from the University of Chicago Medicine suggests that parental incarceration may be contributing to these health gaps. According to the new study, people who experienced a parent or parental figure’s incarceration anytime before the age of 18 had higher levels of hypertension and coronary disease biomarkers than people whose parents were not incarcerated. These results indicate that mass incarceration may have transgenerational health consequences. Adverse childhood experiences (ACEs) are difficult ...
