Ocean acidification and carbon limitation affect photosynthetic capacity of the seagrass (Amphibolis antarctica) and its calcifying epiphytes
Amphibolis antarctica seagrass meadows, and their associated calcifying epiphytes, are abundant on Australia’s west coast, but have declined in recent years due to anthropogenic factors such as marine heatwaves, damaging fishing practices and increased turbidity resulting from eutrophication which causes light limitation. Burning fossil fuels has increased the flux of CO2 in to the ocean, lowering surface seawater pH, and making more carbon available for photosynthetic life. There are benefits of increasing CO2 for those seagrasses that are carbon limited, as this alleviates their energetic use of carbon concentrating mechanisms (CCM’S) which are less efficient, and more energy costly than passive diffusion of CO2 across cell walls. This study used pulse amplitude modulation fluorometry to quantify relative electron transport rates (rETR) at a range of pH levels both above and below current ocean pH of 8.1, and found that A. antarctica has significantly decreased rETR at pH treatments of 7.81 and 7.61. Calcifying epiphytes on A. antarctica also had a significant drop in rETR at the lower pH treatments. There was also significantly lowered rETR at higher pH treatments, likely the result of carbon limitation. These results from the lower pH tests may have profound implications for A. antarctica meadows under ocean acidification. A decline in these meadows would cause the loss of ecosystem services provided by them, such as carbon storage and sequestration, commercial fisheries and a decline the abundance of biodiversity that they support
Mental Health Literacy for Children with a Parent with a Mental Illness [English and Spanish versions]
Promoting mental health literacy is an effective strategy to protect the wellbeing of parents with mental illness and their children. Mental health literacy is part of health literacy; it is defined as “one’s level of understanding about mental health attitudes and conditions, as well as one’s ability to prevent, recognize, and cope with these conditions” (Jorm et al., 1997 p. 182). Mental health literacy can be developed by mental health providers discussing mental illness, recovery, and coping with parents and family members, including children. Increased mental health literacy leads to engagement in mental health promotion and (for the child) prevention focused activities (Beardslee, Solantaus, Morgan, Gladstone, & Kowalenko, 2013).

Asian Longhorned Tick
The Asian longhorned tick (Haemophysalis longicorns Neumann; alternative names include Asian longhorned tick, Asian tick, bush tick, New Zealand cattle tick) is a species of hard tick in the family Ixodidae. It is native to eastern China, Japan, the Russian Far East and Korea. It has also established in Australia, New Zealand and several Pacific islands, where it is considered a severe exotic pest of livestock. In late 2017, the United States Department of Agriculture’s National Veterinary Services Laboratories (NVSL) confirmed the presence of the Asian longhorned tick in the United States. These ticks were first identified in New Jersey, but have since been found in archival samples from West Virginia as far back as 2010. The origin of the tick in the US remains unknown. Some possible routes of entry include entering on domestic pets, horses, livestock or humans. The real impact of the introduction of this tick into the US is not clear at this time, but animal health officials are concerned about potential detrimental impacts on livestock and wildlife
Spin-orbit interaction and anomalous spin relaxation in carbon nanotube quantum dots
We study spin relaxation and decoherence caused by electron-lattice and
spin-orbit interaction and predict striking effects induced by magnetic fields
. For particular values of , destructive interference occurs resulting in
ultralong spin relaxation times exceeding tens of seconds. For small
phonon frequencies , we find a spin-phonon noise
spectrum -- a novel dissipation channel for spins in quantum dots -- which can
reduce by many orders of magnitude. We show that nanotubes exhibit
zero-field level splitting caused by spin-orbit interaction. This enables an
all-electrical and phase-coherent control of spin.Comment: 19 pages, 12 figure
