Hard to swallow: Coral cells seen engulfing algae for first time
For the first time, scientists have seen stony coral cells engulf dinoflagellates - single-celled, photosynthetic algae that are crucial for keeping coral alive. The researchers cultured endoderm-like cells from the stony coral, Acropora tenuis. Around 40% of coral cells incorporated the algae in around 30 minutes and remained healthy for one month. The research is a step towards understanding the partnership between coral and dinoflagellates and could shed light on how coral bleaching occurs.

Physicists describe sun's electric field
A team of physicists led by the University of Iowa have described in fuller detail the sun's electric field. The researchers measured the flow of electrons streaming from the sun as the Parker Solar Probe spacecraft made its closest approach to date to our home star. Result appear in The Astrophysical Journal.

UTA researcher publishes study showing economic impacts of combating sea-level rise
Sea-level rise threatens to produce more frequent and severe flooding in coastal regions and is expected to cause trillions of dollars in damages globally if no action is taken to mitigate the issue. However, communities trying to fight sea-level rise could inadvertently make flooding worse for their neighbors, according to a new study from researchers at UT Arlington and the Stanford Natural Capital Project published in Proceedings of the National Academy of Sciences.

Compound derived from turmeric essential oil has neuroprotective properties
Researchers from Kumamoto University, Japan have found that a component derived from turmeric essential oil, ar-turmerone, and its derivatives act directly on dopaminergic neurons to exert a neuroprotective effect on tissue cultures of a Parkinson's disease model. The effect appears to be due to the enhancement of cellular antioxidant potency through Nrf2 activation. The researchers believe that the ar-turmerone derivatives identified in this study can be utilized as new therapeutic agents for Parkinson's disease.

Putting a load on: Load stimulates bone formation via expression of osteocrin
Researchers from the National Cerebral and Cardiovascular Center Research Institute have found that physical load stimulates expression of the peptide osteocrin (OSTN) to make bone. They found that OSTN expression was high in bones such as the tibia, radius, and ulna, and was increased via stimulation by load and decreased when load was reduced. These results will be useful for promoting bone maintenance in patients restricted to long-term bed rest, and for treating frailty syndrome.

DNA from 1,600-year-old Iranian sheep mummy brings history to life
A team of geneticists and archaeologists from Ireland, France, Iran, Germany, and Austria has sequenced the DNA from a 1,600-year-old sheep mummy from an ancient Iranian salt mine, Chehrābād. This remarkable specimen has revealed sheep husbandry practices of the ancient Near East, as well as underlining how natural mummification can affect DNA degradation.

Baylor study evaluates biodiversity impacts of alternative energy strategies
Climate change mitigation efforts have led to shifts from fossil-fuel dependence to large-scale renewable energy. However, renewable energy sources require significant land and could come at a cost to ecosystems. A new study led by Ryan McManamay, Ph.D., assistant professor of environmental science at Baylor University, evaluates potential conflicts between alternative energy strategies and biodiversity conservation.
