Mark Zuckerberg isn’t particularly shy about copying a good idea when he sees one.

From cribbing Snapchat’s stories feature to cloning TikTok in the form of Instagram Reels, the Facebook co-founder has a long and well-documented history of being a copycat.

Zuckerberg’s latest not-quite-innovation comes in the form of Threads, an Instagram-based Twitter competitor.

A pair of scientists has produced a research paper in less than an hour with the help of ChatGPT — a tool driven by artificial intelligence (AI) that can understand and generate human-like text. The article was fluent, insightful and presented in the expected structure for a scientific paper, but researchers say that there are many hurdles to overcome before the tool can be truly helpful.

By holding the chatbot’s hand at every step, researchers produced a paper that was fluent and insightful. Yet they still have concerns.

Many of us have images we want improved?

If you’ve ever wished your camera had a few more megapixels so you could zoom in on details on your computer screen, or blow up your favourite photos to print, Gigapixel AI might be just the solution.

The joint research team of Electrical Engineering and Computer Science Professor JeongHo Kwak at the DGIST and Aerospace Engineering Professor Jihwan Choi at the KAIST have proposed a novel network slicing planning and handover technique applicable to next-generation low-Earth orbit (LEO) satellite network systems. Findings of the study have been published in the journal IEEE Vehicular Technology Magazine.

LEO satellite networks refer to communications networks with satellites launched within 300–1,500km, established for a stable supply of Internet services. Unlike base stations on land in which radio signals are often interfered with by mountains or buildings, LEO satellites can be launched to build communications networks to places with low population density where base stations could not be set up, thereby allowing them to receive the spotlight as a next-generation satellite communications system.

Accordingly, as more and more satellites are placed in lower orbits, satellite networks are expected to be formed as an alternative to terrestrial networks using links between LEO satellites. However, LEO satellites move in predictable orbits, and their connection within the network is wireless, which is why LEO satellite networks must be considered from a different view than terrestrial networks.

Anuva Kakkar, the 23-year-old entrepreneur behind Tiggle, an Agra-based D2C organic hot chocolate brand, has come a long way in a very short period despite the ongoing COVID-19 pandemic. From selling cups of hot chocolate to commuters outside the DLF Phase-3 metro station in Gurugram to starting her brand of hot chocolate powder and selling over 2 lakh cups through 2021, it has been a mercurial rise.

Made of premium cocoa sourced from a 40-acre family-owned certified organic farm near Pollachi, Tamil Nadu, Tiggle today sells three ‘premium’ varieties of hot chocolate powder — Light Hot Chocolate Mix, Dark Hot Chocolate Mix and Jaggery Hot Chocolate Mix. So, how did this entrepreneur from Agra set up her venture in such a challenging time for commerce?

Robots are often designed for a particular purpose, but what if they could transform to tackle new challenges. Enter M4, the multi-modal mobility morphobot. It draws inspiration from the natural world by adapting how it uses its limb-like rotors and wheels to move in a wide range of ways, saving energy and making it more versatile.

Many cancer cells carry too many or too few chromosomes, a condition known as aneuploidy. Scientists have known this for a very long time, but the impact of aneuploidy has been unclear. Researchers recently developed a computational tool that analyzed cells from thousands of cancer patients. This effort identified critical regions of chromosomes that can be harmful or beneficial to tumor cells when they are deleted or duplicated. The findings have been reported in Nature.

In this study, the investigators developed a method called BISCUT (Breakpoint Identification of Significant Cancer Undiscovered Targets), which located where major changes start and end in chromosomes. Regions that were often found were more likely to help cancer cells survive while less commonly found regions were associated with a lack of cancer cell growth or their death. For example, one-third of all cancer cells in The Cancer Cell Genome Atlas lack one arm of chromosome 8.
