Scientists have found that developmental change from the vegetative-to-reproductive transition happens over the course of a few days. During the transition, plants slow down the leaf growth and instead develop reproductive organs. This transition starts the process of nutrients in the leaves being diverted into the reproductive organs of the plant and eventually into their fruits and…

In high altitudes, despite the air being of low density, which makes the bird wings produce less lift and more difficult to remain aloft, high-altitude birds such as bar-headed geese, cranes, and bar-tailed godwits have been seen at high altitudes of over 6,000Â metres. One possibility of how birds at high altitudes take to the air…
Butterflies and moths collect so much static electricity whilst in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimetres or centimetres. The finding, published in the Journal of the Royal Society Interface, suggests that this likely increases their efficiency and effectiveness as pollinators. The University of Bristol team also observed…
This is “Retroreflector”, the device that Pragyaan rovers on both Chandrayaan 2 and Chandrayaan 3 carried. It reflects light incident on it in a specific direction. | Photo Credit: NASA Q: The landers of the Chandrayaan 2 and the Chandrayaan 3 missions both aimed for a patch on the moon’s surface between the craters X…
A new study has found that maternal Zika virus infections can reprogramme foetal immune development, leading to long-term consequences in children’s immunity. These changes even occur in children born without the physical characteristics associated with congenital Zika syndrome — suggesting that the 95% of babies born of Zika-infected pregnancies who did not exhibit symptoms may have been affected by…
