US researchers say they have created the world’s first genetically modified monkeys by merging cells from up to six different embryos, in what could be a big advance for medical research. Until now, rodents have been the primary creatures used to make chimeras, a lab animal produced by combining two or more fertilised eggs or [...]
Every star twinkling in the night sky plays host to an average of 1.6 planets, a new study suggests. That implies there are some 10 billion Earth-sized planets in our galaxy. Using a technique called gravitational microlensing, an international team found a handful of exoplanets that imply the existence of billions more. The findings were [...]
From grandma’s home remedies for cough, cold and other ailments, ‘tulsi’ (Indian Basil) is now being tested by Indian scientists for treating people exposed to harmful radiations and initial tests have shown some positive results. Scientists at the Defence Research and Development Organisation (DRDO) have developed a tulsi-based herbal medicine for treating people exposed to [...]
A rock found in Russia’s Koryak Mountains might be older than anything on Earth’s surface, say researchers at Princeton. Researchers believe it may have formed in the early solar system – before the Earth. It contains a baffling crystal of a sort that researchers previously believed never occurred in nature – and could only be [...]
A LONG-HELD secret of plants – what they get up to at night – has been revealed. Scientists had assumed they did very little because, in the darkness, they could not use the sun’s energy to carry out photosynthesis. But recently it has been found that plants transport and lose a surprising amount of water [...]
By comparing the genomes of 29 different mammals, US scientists have discovered the vast majority of the so-called “dark matter” in the human genome that could explain genetic variability in cancer and other diseases. “The discovery of this regulatory network fills in a missing piece in the puzzle of cell regulation and allows us to [...]
