Melatonin: finally, a supplement that actually boosts memory
Researchers at Tokyo Medical and Dental University (TMDU) showed that melatonin's metabolite AMK can enhance the formation of long-term memories in mice. Memory of objects were tested after treatment with melatonin or two of its metabolites. Older mice that normally performed poorly on the memory task showed improvements as dosage increased. The metabolite AMK was found to be the most important as melatonin failed to improve memory if it was blocked from metabolizing into AMK. (2020-12-10)

(2020-06-15)

Do urban fish exhibit impaired sleep?
Melatonin controls the body clock -- high melatonin levels make us feel tired in the evening. However, the hormone also plays an important role in animals' biological rhythms. Artificial light at night -- light pollution -- can suppress the production of melatonin in fish, even at very low light intensities, a finding established by researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB). (2020-04-03)

Melatonin may not help prevent delirium after heart surgery
Delirium is observed in approximately 15% of hospitalised older adults, and it is more common in the critically ill and in those undergoing major surgery, such as heart surgery. Studies have found that blood levels of melatonin, a serotonin-derived hormone, decrease following surgery and are lower in surgical patients who develop delirium. A new study published in the Journal of the American Geriatric Society found that melatonin treatment did not influence the risk of developing delirium following heart surgery, however. (2019-10-09)

Genes 'lost' in whales and dolphins helped their ancestors transition to life underwater
When cetaceans (whales, dolphins, and porpoises) transitioned from life on land to life in the sea about 50 million years ago, 85 genes became inactivated in these species, according to a new study. While some of these gene losses were likely neutral, others equipped cetaceans with ''superpowers'' for surviving in the open ocean, facilitating deep dives and paving the way for (2019-09-25)

Melatonin is a potential drug for the prevention of bone loss during space flight
Melatonin could be a novel drug for preventing bone loss of astronauts during space flight. Here we used goldfish scales as a bone model of coexisting osteoclasts and osteoblasts and demonstrated that melatonin synthesis decreased under microgravity. Melatonin treatment of scales stimulated expression of Calcitonin, an osteoclast-inhibiting hormone, and decreased expression of an osteoclastogenesis promotor. This is the first study to report the inhibitory effect of melatonin on osteoclast activation, which is cancelled by microgravity. (2019-09-03)

The study indicates that by simply limiting their exposure to blue-light emitting devices in the evening, adolescents can improve their sleep quality and reduce symptoms of fatigue, lack of concentration and bad mood, after just one week. (2019-05-19)

Researchers create the first maps of two melatonin receptors essential for sleep
An international team of researchers used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to create the first detailed maps of two melatonin receptors that tell our bodies when to go to sleep or wake up and guide other biological processes. A better understanding of how they work could enable researchers to design better drugs to combat sleep disorders, cancer and type 2 diabetes. Their findings were published in two papers today in Nature. (2019-04-24)

Addressing sleep disorders after traumatic brain injury
Amsterdam, NL, December 10, 2018 - Disorders of sleep are some of the most common problems experienced by patients after traumatic brain injury (TBI). It is important to recognize and treat these problems early to allow for optimal cognitive recovery, but because they are so common, the importance of treating them is often underestimated. In this special issue of NeuroRehabilitation scientists address the interplay of sleep and TBI with the aim of improving both diagnosis and treatment of these problems. (2018-12-10)
