Evaluation of Waning of SARS-CoV-2 Vaccine–Induced Immunity

JAMA Network Open

2023-05-03

(Press-News.org) About The Study: The findings of this systematic review and meta-analysis of secondary data from 40 studies suggest that the effectiveness of COVID-19 vaccines against laboratory-confirmed Omicron or Delta infection and symptomatic disease rapidly wanes over time after the primary vaccination cycle and booster dose. These results can inform the design of appropriate targets and timing for future vaccination programs.

Authors: Piero Poletti, Ph.D., of the Bruno Kessler Foundation in Trento, Italy, is the corresponding author.

Researchers capture elusive missing step in the final act of photosynthesis

2023-05-03

Menlo Park, Calif. – Photosynthesis plays a crucial role in shaping and sustaining life on Earth, yet many aspects of the process remain a mystery. One such mystery is how Photosystem II, a protein complex in plants, algae and cyanobacteria, harvests energy from sunlight and uses it to split water, producing the oxygen we breathe. Now researchers from the Department of Energy’s Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory, together with collaborators from Uppsala University and Humboldt University and other institutions have succeeded in cracking a key secret of Photosystem II. Using SLAC’s Linac Coherent Light ...

Association between depression and physical conditions requiring hospitalization

2023-05-03

About The Study: In this study that included 240,000 individuals, the most common causes of hospitalization in people with depression were endocrine, musculoskeletal, and vascular diseases, not psychiatric disorders. These findings suggest that depression should be considered as a target for the prevention of physical and mental disease. Authors: Philipp Frank, Ph.D., of University College London, is the corresponding author.

Astronomers witness star devouring planet: possible preview of the ultimate fate of Earth

2023-05-03

By studying countless stars at various stages of their evolution, astronomers have been able to piece together an understanding of the life cycle of stars and how they interact with their surrounding planetary systems as they age. This research confirms that when a Sun-like star nears the end of its life, it expands anywhere from 100 to 1000 times its original size, eventually engulfing the system’s inner planets. Such events are estimated to occur only a few times each year across the entire Milky Way. Though past observations have confirmed the aftermath of planetary engulfments [1], ...

Discovery suggests route to safer pain medications

2023-05-03

Strategies to treat pain without triggering dangerous side effects such as euphoria and addiction have proven elusive. For decades, scientists have attempted to develop drugs that selectively activate one type of opioid receptor to treat pain while not activating another type of opioid receptor linked to addiction. Unfortunately, those compounds can cause a different unwanted effect: hallucinations. But a new study led by Washington University School of Medicine in St. Louis has identified a potential route ...

XFELs show the final milliseconds of oxygen formation

2023-05-03

For the first time, scientists have been able to see the crucial final step in the reaction cycle of Photosystem II, during which oxygen is formed. Using serial femtosecond crystallography performed with the XFEL technique, they have managed to obtain more information on the interaction between Photosystem II and the Mn/Ca cluster. This has been shown in a new study by Uppsala University, published in the journal Nature. The oxygen we breathe is produced by plants, algae and cyanobacteria, which use the energy of sunlight for powering the formation of oxygen. This is done by the Photosystem II enzyme, ...

To boost cancer immunotherapy’s fighting power, look to the gut

2023-05-03

Cancer immunotherapy has transformed the treatment of many types of cancer. Yet, for reasons that remain poorly understood, not all patients get the same benefit from these powerful therapies. One potent factor in treatment outcome appears to be an individual’s gut microbiota — the trillions of microorganisms that live in the human intestine — according to new research led by investigators at Harvard Medical School and Dana-Farber Cancer Institute. The study, done in mice and published May 3 in Nature, pinpoints how gut microbes enhance the body’s response to a common type of immunotherapy known as PD-1 checkpoint ...

Minoan eruption survey improves volcanic risk assessments

2023-05-03

Volcanic eruptions are spectacular, violent and dangerous. Large explosive eruptions can even have global impacts. To classify the size of volcanic eruptions, the magma volume and the deposition volume are determined. Volcanologists estimate these values in order to compare the size of different volcanic eruptions or to obtain a measure of the explosiveness of the eruption. However, it is often not possible to determine the values accurately. This makes it difficult to infer the actual volume of magma and to measure the complete extent of such eruptions. In particular, because the deposits of the most violent historical eruptions are partially or completely under water, which makes geological ...

Indo-Pacific corals more resilient to climate change than Atlantic corals

2023-05-03

UNIVERSITY PARK, Pa. — In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team led by Penn State has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic. Coral reefs are vast geological structures made of calcium carbonate produced by coral animals whose colonies possess dense populations ...

More woodlands will not impact tourism

2023-05-03

Hiking, cycling, climbing and boating. When we take time off from work or school, we like to go out into nature. The landscape in other words play an important role for our vacations. To promote biodiversity and carbon sequestration there is a focus on planting more trees, especially in upland areas such as Howgill Fells. The Howgill Fells is located in the north-west of England and is known for its soft, rolling and open landscape.  It is a popular area for tourists seeking the outdoors and hill-walking in particular. But how ...

Used coffee pods can be recycled to produce filaments for 3D printing

2023-05-03

An article published in the journal ACS Sustainable Chemistry & Engineering brings good news for coffee buffs: the plastic in used coffee pods can be recycled to make filament for 3D printers, minimizing its environmental impact. The solution was successfully tested by research groups in Brazil at the Federal University of São Carlos (USFCar) and the State University of Campinas (UNICAMP), and in the United Kingdom at Manchester Metropolitan University (MMU). “We produced new conductive and non-conductive filaments from waste polylactic acid [PLA] from used coffee machine ...
