Nigerian Government Joins Koo

Less than a week after banning American microblogging site Twitter indefinitely, the Nigerian government has joined its India-made rival Koo. Shortly after the ban, Koo had announced that it was available in Nigeria and was working to add local languages on its platform.
Nigeria's decision to suspend Twitter in the country reportedly came as a result of the US-based social networking platform deleting a tweet by President Muhammadu Buhari for violating rules. The Nigerian government had alleged that the microblogging site was being used to undermine Nigeria's corporate existence through the spreading of fake news that has violent consequences.

Scientists Create Exotic Outer Space Ice

Researchers from NASA's Jet Propulsion Laboratory and Oak Ridge National Laboratory successfully created amorphous ice, similar to ice in interstellar space and on icy worlds in our solar system. They documented that its disordered atomic behavior is unlike any ice on Earth.
The findings could help interpret data from future NASA missions such as Europa Clipper, which will assess the habitability of Jupiter's moon, Europa.
Using the Spallation Neutron Source's SNAP instrument, the scientists replicated the cold vacuum of space and added a few molecules at a time of heavy water to a plate cooled to 25 Kelvin to produce amorphous ice. They then used neutron scattering to observe the ice's structural changes at varying temperatures before it transitioned to crystalline ice.

SpaceX launches 22nd Resupply Services Mission to ISS

SpaceX has again launched its 22nd resupply services mission called SpaceX CRS 22, using cargo Dragon 2 capsule, to International Space station (ISS).
This is the second mission under new CRS contract of SpaceX with NASA and fifth capsule in last 12 months which SpaceX sent to ISS. The 22nd launch is also the first launch of 2021 on new Falcon 9 rocket booster. Falcon 9 Rocket launch vehicle is carried 7,300 pounds of research materials, supplies, hardware and new solar arrays. It is also carrying a number of research experiments which will be conducted on ISS. It carried a oral bacteria to test germ growth with Colgate toothpaste.

Scientists Develop Chip-Off Technique to Retrieve Encrypted Data

Forensic scientists at Central Forensic Science Laboratory (CFSL) have developed an indigenous chip-off technique which will help the investigative agencies in producing credible evidences against criminals in trial courts. This technique will also help in retrieving encrypted data from locked and severely damaged smart cell phones.
It was developed by scientists Akhlesh Kumar, Bhushan Ghode and Khevna Maniar.
Using the technique, scientists were able to retrieve data from a smart cell phone which were locked with finger prints of a person who died by suicide.
This technique is not successful on mobile device of higher Android or IOS versions including Apple iphones. Data are extracted from such mobile devices are found in an encrypted condition and methods of decryption are still under development. This technique can be used only if competent court grants permission.

Microsoft to Unveil Next Generation of Windows

Tech giant Microsoft will unveil the next generation of Windows on June 24. The announcement comes a week after the company's CEO Satya Nadella teased major upgrades to the PC operating system for developers and creators.
The tech giant had confirmed last month that Windows 10X, its OS originally built for dual-screen devices, will no longer ship. The company is now rolling the visual elements of Windows 10X into the main version of Windows 10 instead.

NASA Announces Two New Missions

NASA has announced that it is sending two new missions to Venus in order to examine the planet's atmosphere and geological features.
The missions, which have each been awarded $500m (£352m) in funding, are due to launch between 2028 and 2030.
NASA administrator Bill Nelson said that the missions would offer the chance to investigate a planet we haven't been to in more than 30 years.
The last US probe to visit the planet was the Magellan orbiter in 1990.
However, other spacecraft - from Europe and Japan - have orbited the planet since then.
The missions were picked following a peer review process and were chosen based on their potential scientific value and the feasibility of their development plans.
The DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission will measure the planet's atmosphere to gain insight into how it formed and evolved. It will also aim to determine whether Venus ever had an ocean.
The second mission, VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy), will map the planet's surface to understand its geological history and investigate how it developed so differently than Earth.
