Iceland's 1st lost glacier

RIP, Okjokull glacier. Iceland on Sunday honors the passing of Okjokull, as scientists warn that some 400 others on the subarctic island risk the same fate. With a theme of fighting climate change, about 100 Icelanders have said farewell to what once was a glacier. 

Scientists said it was the first of Iceland's glaciers to disappear because of climate change. About 100 years ago, the glacier covered almost 6 square miles of a mountainside in western Iceland and measured more than 160 feet thick. A plaque has been installed at the site of the former glacier, which reads: "In the next 200 years, all our glaciers are expected to follow the same path. 

This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it." The plaque bears the inscription "A letter to the future," and is intended to raise awareness about the decline of glaciers and the effects of climate change.


Some store more bad memories

Depression-prone people may naturally form and store more negative memories than others, that are just waiting to be triggered by conflict, a new study suggests. Researchers from McGill University studying mice that were more susceptible to depression found they stored more units of bad memories in their brains and were more likely to have these memories reactivated. 

People who are depressed can hardly help but to see everything - past memories and present experiences alike - in a negative light, and scientists hope that finding differences in how their brains store information on a cellular level may explain why.

Kimchi cures baldness?

It is known for helping maintain a healthy gut, but now scientists have found kimchi could be used to reverse hair loss. The South Korean dish of fermented cabbage, onions, garlic, fish sauce and spices is already popular with health-conscious consumers and known for its probiotic qualities. 

But research shows a kimchi drink sold in South Korea helps thicken existing hairs and grow new ones within weeks. Researchers at Dankook University near Seoul studied 23 men, some in the early stages of hair loss and others visibly thinning on top. They were told to have a kimchi drink before breakfast and at bedtime. After a month, the average number of hairs had risen from about 85 per sq cm of scalp to 90, and then 92 after four months of drinking the liquid. 

The scientists said this was a significant increase that appeared to have reversed hair loss in most of the men. In a report on the findings, published in the World Journal of Men's Health, the researchers said: "Current drugs can have adverse effects so their use is usually temporary. We found kimchi could promote hair growth and reverse baldness. It is a safer treatment strategy for patients."


Plastic waste in Arctic

An abundance of tiny plastic particles have been found in ice cores drilled in the Arctic by a US-led team of scientists, underscoring the threat the growing form of pollution poses to marine life in even the remotest waters on the planet. 

The researchers think microplastics are being blown about by winds and then transported long distances through the atmosphere. The particles are then "washed" out of the atmosphere through precipitation, particularly snow. The discovery is especially disturbing because, according to the study, "the Arctic is still widely conceived as one of the last pristine environments on the globe."
