INSIGHT
INSIGHT, NASA's robotic Mars lander has recorded a likely mars quake for the first time ever.  The US space agency said the seismic signal, detected by the Seismic instrument, was recorded.  NASA said this is the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind.

Echidna milk could be an alternative to antibiotics
The milk of Echidna - an egg laying mammal - contains a novel anti-microbial protein that may be used as alternatives to the present antibiotics, scientists have found.
Scientists in the council of Scientific & Industrial Research (CSIR) - Centre for Cellular and Molecular Biology (CCMB) have found The anti-microbial protein (AMP), identified in the milk secreted by the anteater or Echidna, has been found to keep the young ones at bay from infections.
Usually Antibiotics are required and mild pain relievers can help with discomfort.

Nepal’s first satellite NepaliSat-1 was launched into space
It was launched from the Virginia-based station of the National Aeronautics and Space Administration (NASA) in the US.
NepaliSat-1 was developed by two Nepalis Abhas Maskey and Hariram Shrestha at Japan’s Kyushu Institute of Technology.

It will start rotating around the Earth’s orbit to collect information about the country’s topography and Earths magnmagnetic field.
It is equipped with a 5MP camera to capture Nepal’s topography and a magnetometer to collect data related to the Earth’s magnetic field. The images and data will be sent by satellite to the ground station at NAST.

Sri Lanka’s 1st satellite ‘Raavana-1’ launched into space

It was launched into space from NASA’s Flight Facility on Virginia’s east shore. This marks Sri Lanka’s entry into the global space age.
‘Raavana 1’ weights around 1.05 kg and the lifespan of the satellite is around one and a half years. Its camera mission is to capture images of Sri Lanka and its neighboring countries.
The satellite was designed and built at the Kyushu Institute of Technology in Japan by two Sri Lankan research engineers.
Scientists detect the first-ever molecule of the universe
The first molecule that ever formed in the universe, the elusive helium hydride, has finally been detected in space, ending a 94-year search for what is believed to mark “the dawn of chemistry”.
The ion HeH+ was the first molecular bond to ever exist in the universe, taking shape around 300,000 years after the Big Bang.
The findings have been detailed in a study published in the journal Nature.

Lakes filled with liquid methane spotted on Saturn’s moon Titan
Scientists provided the most comprehensive look to one of the solar system’s most exotic features.
Using data obtained by NASA’s Cassini spacecraft before that mission ended in 2017.
The Scientists, with a deliberate plunge into Saturn, have found that some of frigid Titan’s lakes of liquid hydrocarbons in this region are surprisingly deep while others may be shallow and seasonal.
Titan and Earth are the solar system’s two places with standing bodies of liquid on the surface.

'First' 3D print of heart with human tissue, vessels unveiled

Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels making it a first and a "major medical breakthrough" that advances possibilities for transplants.
The heart produced by researchers at Tel Aviv University is about the size of a rabbit's.
The heart marked the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers.
But the scientists were skeptical about the challenges remain before fully working 3D printed hearts will be available for transplant into patients.

Israel's Beresheet spacecraft crashes on Moon

An Israeli space craft has crashed into the lunar surface, ending the first privately funded attempt to land on the moon.
The robotic lander about the size of a washing machine, the 585 kg experienced an engine and communication failure in the last seconds of touchdown.
Israel is the seventh country to orbit the moon and the fourth to reach the lunar surface.

April 11

First-ever black hole image released
The first ever image of a black hole, which is named as POWEHI by a Hawaii University professor, which is located 500 million trillion kilometers away, in a distant galaxy by the Astronomers.
The image which has been captured by a network of eight telescopes across the world, shows an intensely bright 'ring of fire' surrounding a perfectly circular dark hole.
Astrophysicist and Project Director Sheperd Doeleman said that the image is the strongest evidence of the existence of black holes. He termed it as a remarkable achievement in the field of astrophysics

April 8

Scientists at the Centre for Cellular & Molecular Biology (CCMB) have discovered a new enzyme ‘Murein Endopeptidase’ which helps in breaking cell walls of bacteria.
This discovery offers a potential for a new drug delivery route to arrest the anti-bacterial resistance through existing antibiotic drugs.
Antibiotics are medicines used to prevent and treat bacterial infections.
It opens up fresh ways to target microbes, leading to a new wave of antibiotic drugs.
The person behind this discovery is Pavan Kumar research student and his mentor Dr. Manjula Reddy.

April 7

The germ, a fungus called Candida Auris preys on people
Candida auris, preys on people with weakened immune systems, and it is quietly spreading across the globe.

Amphibian pandemic killed 90 species

Deadly disease affecting amphibians has descended into a global pandemic out break
A prominent US biologist Jonathan Kolby, at the World Organisation for Animal Health Aquatic Conference in Santiago, Chile, disclosed that a deadly disease affecting amphibians has descended into a global pandemic and it has already wiped out 90 species. He warned that the disease attacks the skin of frogs, toads and other amphibians. 
It is the habit of these creatures to use their skin to breathe and regulate their bodies' water levels, the damage caused by the disease eventually leads to heart failure and death.
Over the past five years, the highly contagious disease has already caused nearly 90 species to disappear, with over 500 impacted.

April 2

Researchers found similarities between the groundwater moving mechanisms in the Sahara and on Mars.

The researchers at University of Southern California (USC) said that the deep groundwater could still be active on Mars.

This suggests both may have had wet periods long enough to create such an active groundwater system.

It was found that groundwater likely existed in a broader geographical area than just the poles of Mars.

April 1

ISRO is launching defense satellite PSLV C-45, EMISAT along with 28 foreign satellites on April 1, 2019.
As stated by the sources, this low-Earth orbit satellite will monitor and give locations for enemy radar sites deep in their territory.
Till now, India was using airplanes as early warning platforms, but this satellite will give a space-based platform to sniff out enemy radars.
For the first time, Indian Space Research Organisation (ISRO) invited common people to view the launch.
The Indian Space Research Organisation (ISRO) opened a visitors' gallery with 5,000 capacity at Andhra Pradesh's Sriharikota.
