New Drug could Treat Most Aggressive Form of Lung Cancer Scientists have found a new drug that could possibly treat small cell lung cancer, the most destructive form of the disease. Currently, this drug is undergoing clinical trials and could potentially be used to treat patients who have tumours that are not affected by chemotherapy treatment. The findings were published in the Clinical Cancer Research and could help in finding out those patients who have greater chances to respond to the treatment. The medication works by analyzing energy production in cancer cells as a means to prohibit tumour growth. Professor Caroline Dive, the leader of the research, said that small cell lung cancer has a dim prognosis and there has not been any significant breakthrough in its treatment. The drug named AZD3965 – has not yet been experimented with in small cell lung cancer. The quality of life has undoubtedly become rich with these major scientific breakthroughs, howe...

REAL-TIME DIVERGENT EVOLUTION IN PLANTS DRIVEN BY POLLINATORS Daniel D. L. Gervasi & Florian P Schiestl Nature Communications volume 8, Article number: 14691 (2017) Pollinator-driven diversification is thought to be a major source of floral variation in plants. Our knowledge of this process is, however, limited to indirect assessments of evolutionary changes. Here, we employ experimental evolution with fast cycling Brassica rapa plants to demonstrate adaptive evolution driven by different pollinators. Our study shows pollinator-driven divergent selection as well as divergent evolution in plant traits. Plants pollinated by bumblebees evolved taller size and more fragrant flowers with increased ultraviolet reflection. Bumblebees preferred bumblebee-pollinated plants over hoverfly-pollinated plants at the end of the experiment, showing that plants had adapted to the bumblebees’ preferences. Plants with hoverfly pollination became shorter, had reduced emission of s...
Circadian Rhythm Circadian clocks Plants contain several tissue-specific decentralized but communicating ‘clocks’. These control developmental outputs in response to environmental change: the vasculature clock for photoperiodic control of flowering, and the epidermis clock for temperature-dependent elongation.
