Need to tell AI-made deepfakes from real pics? Call astronomers

Using innovative strategies that astronomers use to identify the shape of distant, dim galaxies, Adejumoke Owolabi, a master’s student at the University of Hull, and her mentor Kevin Pimbblet, a professor of astrophysics and director of the Centre of Excellence for Data Science, Artificial Intelligence and Modelling at the University of Hull, have described a…

‘STEMinism is an attempt to bring more women into science without critiquing the field of science’

Dr. Gita Chadha from her recent talk at BIC | Photo Credit: Ravi Kumar Boyapati Dr. Gita Chadha says that the portmanteau word STEMinism makes her uneasy. “The term very nobly is used to describe the move to bring more women into science, technology, engineering and maths with the belief that this is essentially empowering…

Indian scientists build breakthrough gene-editor, aim for patent

Scientists from the CSIR-Institute of Genomics and Integrative Biology, New Delhi, have developed an enhanced genome-editing system that can modify DNA more precisely and more efficiently than existing CRISPR-based technologies. CRISPR occurs naturally in some bacteria, as a part of their immune system that limits infections by recognising and destroying viral DNA. In Nobel-prize winning…

Charles Darwin’s frog | Photo Credit: S.D. Biju In a pioneering study featured in the Harvard Museum of Comparative Zoology’s journal Breviora, an Indo-American team of biologists has discovered an extraordinary reproductive behaviour in the Charles Darwin’s frog (Minervarya charlesdarwini), an endangered species endemic to the Andaman Islands. This discovery not only highlights the rare…

Butterflies accumulate enough static electricity to attract pollen

Butterflies accumulate enough static electricity to attract pollen

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…

How reliable are studies that show moderate drinking has health benefits?

The notion that a glass of wine a day is good for health or some variation of it is based on flawed scientific research, says a study. Similarly, many published studies have linked moderate drinking to health benefits by comparing them with abstainers, leading to the widespread belief that alcohol, in moderation, can be a…

What life feels like when earth’s temperatures soar to record highs

In the unrelenting heat of Morocco’s Middle Atlas, people were sleeping on rooftops. Hanna Ouhbour needed refuge too, but she was outside a hospital waiting for her diabetic cousin who was in a room without air conditioning. On Wednesday, there were 21 heat-related deaths at Beni Mellal’s main hospital as temperatures spiked to 48.3 degrees…

A view of Ariel composed by NASA/JPL-Caltech, December 12, 2016. | Photo Credit: Kevin M. Gill The Solar System has many mysteries. We don’t know why the Sun’s corona is so hot. We don’t know why Saturn’s moon Titan has such a significant atmosphere. We don’t know why Triton rotates in the direction opposite to…
