A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally.

Cultured meat (also known as cell-based or lab-grown meat) is a promising, more environmentally friendly alternative to meat produced from traditional livestock farming. However, production costs are still high and need to be reduced before it can become widely available.

Now, researchers from Singapore and China have found a way to use food waste for culturing meat, reducing production costs and helping to make cultured meat a viable option for feeding the world’s population.

Scaling up production

Growing in the heart of the world’s deepest valley are two plants that have fooled scientists for decades.

Two species of the ‘touch-me-not’ genus (Impatiens) – the Blue Diamond (Impatiens namchabarwensis) and Toothed Busy Lizzie (Impatiens arguta) are found in the remote Tsangpo Gorge that meanders around the highest peak in the Eastern Himalayas, Mount Namchabarwa.

Both plants are adorned with trumpet-shaped flowers in a spectrum of colours, and their similarities made many scientists believe they belonged to the same species.

Just as a superb meal requires the right ingredients prepared expertly, the production of better green fuel alternatives requires combining the right materials and methods.

Recently, a team of researchers from China and the UK have found new ways to optimise the recipe for the production of solar fuels.

 For the 314,000 people diagnosed with ovarian cancer each year, hope often comes in the form of platinum-based drugs such as cisplatin.

Cisplatin causes the death of quick-dividing tumour cells, so it is a potent first-line defence in the treatment of the often fatal disease.

However, over half of ovarian cancer patients develop recurrence and become resistant to cisplatin and other platinum-based chemotherapies, contributing to the five-year survival rate of 31%.
