Lassa fever

Nigeria has announced that it is free from Lassa fever outbreak. The announcement follows the epidemiological review by the Nigeria Centre for Disease Control (NCDC) and the World Health Organisation (WHO).

Lassa fever- key facts:

Lassa fever is an acute viral haemorrhagic illness of 2-21 days duration that occurs in West Africa.

The Lassa virus is transmitted to humans via contact with food or household items contaminated with rodent urine or faeces.

Person-to-person infections and laboratory transmission can also occur, particularly in hospitals lacking adequate infection prevention and control measures.

Lassa fever is known to be endemic in Benin, Ghana, Guinea, Liberia, Mali, Sierra Leone, and Nigeria, but probably exists in other West African countries as well.

National Technology Day

Since 1999, May 11 is celebrated as National Technology Day to mark India’s technological advancements.

National Technology Day 2018 theme: “Science and Technology for a Sustainable Future”.

Significance of the day:

On May 11, 1998, India detonated three nuclear bombs in the Indian Army’s Pokhran Test Range. Dr APJ Abdul Kalam lead the Indian team of scientists to successfully test-fire the Shakti-1 nuclear missile at Rajasthan’s Pokhran test range.

Hansa 3, India’s first indigenous aircraft was first tested on the same day in 1998 in Bangalore.

Successful test firing of Trishul, a short range missile made in India, was also done on the same day.

Every year, on this day, the Technology Development Board of India awards various individuals with national awards for their contribution to indigenous technology.

Bangabandhu Satellite-1

The Bangabandhu Satellite-1 mission will be the first to utilize Falcon 9 Block 5, the final substantial upgrade to SpaceX’s Falcon 9 launch vehicle.

Falcon 9 Block 5 is designed to be capable of 10 or more flights with very limited refurbishment as SpaceX continues to strive for rapid reusability and extremely high reliability.

About Bangabandhu Satellite-1:

Bangabandhu is Bangladesh’s first communications satellite. Built by Thales Alenia Space, a Franco-Italian aerospace manufacturer, it is designed to provide a wide range of broadcast and communication services throughout the country for the next 15 years.

It is named after Bangladesh’s “Father of the Nation”- Bangabandhu Sheikh Mujibur Rahman.


Once operational, citizens of Bangladesh will gain access to the Internet, phone services, radio, backhaul, direct-to-home TV, and other related services.

Elysia chlorotica

It is a green sea slug which can suck out an algae’s plastids that generate energy from sunlight — and incorporate them into its own biology.

In doing so, it becomes an animal with the photosynthetic ability of a plant.

What makes it unique?

What makes Elysia chlorotica unique is it takes only the plastids, or the organelles that contain chlorophyll and perform photosynthesis, from the algae.

The slug then uses its own genome to keep the plastids operating within its own body throughout the rest of its life.

Where is it found?

The sea slug Elysia chlorotica, a mollusk that can develop to a length of 2 inches has been discovered in intertidal zone between Nova Scotia, Canada, and Martha’s Vineyard, Massachusetts, as well as in Florida.

Significance of the discovery:

Figuring out how the slug keeps these algae-made solar panels functioning could lead to innovations in developing green machines that need only sunlight to generate energy or bioproducts that could be used as biodiesel.

Astronomers find first carbon rich asteroid in Kuiper Belt

Astronomers have discovered an unusual carbon-rich asteroid in the Kuiper Belt — the first of its kind to be confirmed in the cold outer reaches of the solar system.

This object, designated 2004 EW95, likely formed in the asteroid belt between Mars and Jupiter and has been flung billions of kilometres from its origin to its current home in the Kuiper Belt.

The researchers found that the asteroid’s reflectance spectrum — the specific pattern of wavelengths of light reflected from an object — was different to that of similar small Kuiper Belt Objects (KBOs), which typically have uninteresting, featureless spectra that reveal little information about their composition.
