When two tigers made their way into a southeastern Bangladesh village, forest officials knew they had to act quickly to save the tigersâ€™ lives.
Climate change is compelling Spanish winemakers to think about moving to higher ground in order to run away from the sweltering heat.
A 265-pound elephant was born in Australia on an effort to help to conserve the scarce Asian elephant.
Canadian scientists say a study involving locusts might lead to new drugs to treat migraine headaches, stroke and epilepsy and other illnesses. Queen's University biologists found such human disorders are caused by a brain disturbance, during which nerve cells shut down.
A Spanish-led study suggests the ability of plants to tell time through a circadian clock might produce information that can improve climate change models. The researchers, led by the University of Castilla la Mancha, said they studied plants' circadian rhythm -- the roughly-24-hour cycle in the biochemical, physiological or behavioral processes of living organism -- from a molecular viewpoint and found an ecological implication -- it makes climate change scenarios and CO2 level figures more accurate. Victor Resco de Dios, the study's lead author, said the research, which appears in the journal Ecology Letters, reveals the ecological implications of plants' ability to tell the time. The clock coordinates when a plant should flower and also when it should germinate a seed, Resco de Dios said, adding the circadian clock has a great capacity to adapt to its physical environment. Plants take up CO2 by means of photosynthesis and can potentially mitigate climate change.
Parents who value strenuous team sports are more likely to influence their children to join a team or at least participate in some kind of exercise, and spend less time in front of the TV or computer, a new study says.
