UK students create 3D-printed coral structures that could rebuild world’s damaged reefs

Technology
Students at the University of Exeter have developed an environmentally friendly technique that could help to rebuild coral reefs.The project, called CalcifEXE, uses genetically modified bacteria to make calcium carbonate, which can then be shaped into coral "backbones" using a 3D printer. The scientists hope they can then attach live coral to the backbones, before placing them in the ocean to grow new reefs."It will be lovely to think that it's going to become a new weapon in the fight against climate change," Dr Mark Hewlett, the students' supervisor, told Sky News.

IT Department to map digital behaviour of taxpayers to create profiles

IT Department to map digital behaviour of taxpayers to create profiles

Finance
The income tax department will map the digital behaviour of taxpayers to create their profiles under faceless scrutiny assessment in electronic mode, a senior official said, as all interactions of a taxpayer with the tax authority will be logged. Faceless assessment will be a complete shift from the earlier practice where taxpayers could sit with the assessing officer and resolve issues at one go, following a single notice of demand, and even seek adjournment for hearings over telephone calls. “If I give you a requisition for five things, you (taxpayer) respond to one, and take adjournment to respond to the other, that’s assessee behavior that is being mapped, which in the manual days was not being mapped,” Smita Jhingran, chief commissioner of income tax at Regional e-Assessment Centre, D...
Scientists move to create single, comprehensive list of Earth’s living species

Scientists move to create single, comprehensive list of Earth’s living species

Science
July 7 (UPI) -- An international group of scientists hope to convince biologists, taxonomists, conservationists and policy makers the world over to use a single, comprehensive list of the world's species -- from mammals and birds to plants, fungi and microbes. On Tuesday, the team of scientists, organized by the International Union of Biological Sciences, published a series of principles in the journal PLOS One that they hope will serve as a roadmap for compiling such a list. Advertisement It's not the first time scientists have called for a big list of all the planet's living things. "There have been attempts to do this, and even quite good ones, such as the Catalogue of Life," IUBN team member Frank Zachos told UPI. "But it is a relatively small group of people that decide which specie...

MoMo ProductionsThe secret to building sustainable income in retirement is right in front of you — and the IRS has had it all along.Retirees generally know all about required minimum distributions. This is the annual withdrawal that you must take from your individual retirement account and 401(k) plans after you turn 70½ — or, starting this year, 72.This calculation is based on your account value as of the end of the prior year, as well as your remaining life expectancy."The RMD can go on until you're 100 or 110, if you live that long," said Steven Vernon, actuary and research scholar at the Stanford Center on Longevity."It's a fairly low withdrawal rate in your 70s, and if you couple it with stock investments, you'll have time for growth."Vernon coauthored a paper in 2017 that a...
