Chocolate Chip Sea Star

June 14, 2026

Chocolate Chip Sea Star Latest News

Scientists recently discovered a remarkable light-transmitting skeletal structure at the tips of the arms of the chocolate-chip sea star, which channels about 70% of incident light and concentrates it nearly threefold at its base.

About Chocolate Chip Sea Star

Chocolate Chip Sea Star, also known as the horned sea star, is a species of highly recognizable ornamental sea star.
Scientific Name: Protoreaster nodosus

Chocolate Chip Sea Star Habitat and Distribution

They are found in the warm, shallow waters of the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the western Pacific Ocean.
They inhabit coral reefs, sandy lagoons, and seagrass beds, typically at depths of up to 30 meters.

Chocolate Chip Sea Star Features

These sea stars can grow up to 12 inches in diameter.
They have a creamy white base and dark brown projections, resembling chocolate chips.
Often they are tan-colored, but they can be other shades as well.
Like all sea stars, these guys can regenerate lost body parts.
When threatened, they can lose one of their five limbs (a process known as autotomy) to escape predators, and the lost limb may regenerate over time.
They are carnivores and typically feed on detritus, small invertebrates, and even the soft tissue of corals.

Chocolate Chip Sea Star Recent Findings

On the tip of each arm, a skeletal part contains an array of cone-shaped structures that, like optic fibres, transmit 70% of incident light and concentrate it nearly 3x at the base.
Overall, the array captures light from a 120° field of view and ‘brightens’ it 8x inside the arm.
Scientists said engineers could use the design for lightweight sensors and displays.

Key Facts about Sea Stars

Although sea stars are often called “starfish,” they’re not related to fish.
They are invertebrates related to sea urchins, sea cucumbers, and sand dollars, which are all echinoderms.
- ‘’Echinoderm’’ means spiny skin—a reference to their hard, calcified skin, which helps to protect them from predators.
They have radial symmetry and tube feet that help them move using water pressure.
There are close to 2,000 species of sea stars in the world’s oceans. Most species have five arms, but some have many more—even as many as 40.
They are often found under rocks or in crevices. Their mouth, on the underside of their body, has no teeth.
When feeding, sea stars wrap their arms around their prey and push their stomach out of their mouth to eat their food.
They’re toxic to some predators, but if captured, sea stars can drop an arm to try to escape.
They can regrow lost arms—and even an entire new body from a single arm and part of the central disc of their body.

Jiangmen Underground Neutrino Observatory (JUNO)

June 14, 2026

Jiangmen Underground Neutrino Observatory (JUNO) Latest News

The Jiangmen Underground Neutrino Observatory (JUNO) collaboration in China recently published its first results, including measurements on how often particles called neutrinos from nuclear reactors change their flavour, or type, as they travel.

About Jiangmen Underground Neutrino Observatory (JUNO)

It is a large underground neutrino detector located near the city of Kaiping in the southern Guangdong province of China.
It is the product of an international collaboration involving 74 institutions from Asia, Europe, and America, and has some 700 members.
It is led by the Chinese Academy of Sciences (CAS) via the Institute of High Energy Physics (IHEP).
It is the second neutrino experiment in China, after the Daya Bay Reactor Neutrino Experiment.
It is located 53 km from two nuclear power plants in Taishan and Yangjiang.
The primary JUNO scientific goal is the determination of the neutrino mass ordering (NMO).
- This can be inferred by measuring the oscillation pattern of electron anti-neutrinos emitted by nuclear power plants.
To do this, the facility has an 80 m high and 50 m diameter experimental hall located 700 m underground.
Its main feature is a 35 m radius spherical neutrino detector, containing 20,000 tonnes of liquid scintillator.
It is the world's largest and highest-precision liquid scintillator detector.
Juno is designed to have a scientific lifespan of up to 30 years.
JUNO is also one of three next-generation neutrino experiments, the other two being the Hyper-Kamiokande in Japan and the Deep Underground Neutrino Experiment in the US.

What are Neutrinos?

Neutrinos, often called 'ghost particles', are elementary particles that belong to the lepton family of particles.
Since neutrinos have very little interaction with matter, their detection is very difficult.
They have no electrical charge and have a very small mass (less than one millionth of the mass of the electron), and their speed is nearly equal to the speed of light.
First predicted in 1930, they weren’t discovered in experiments until 1956.
Of the four fundamental forces in the universe, neutrinos only interact with two — gravity and the weak force.
Source: Neutrinos come from all kinds of different sources and are often the product of heavy particles turning into lighter ones, a process called “decay.”
They are the most common particles in the universe.
Approximately 100 trillion neutrinos pass completely harmlessly through your body every second.
Neutrinos play crucial roles in the standard model of particle physics, in stellar physics and black holes, and even in cosmology and the nature of the Big Bang.

Naval Anti-Ship Missile–Medium Range (NASM–MR)

June 14, 2026

Naval Anti-Ship Missile–Medium Range (NASM–MR) Latest News

India recently concluded successful trials of a multi-layered Ballistic Missile Defence (BMD) system and the maiden flight-test of the Naval Anti-Ship Missile-Medium Range (NASM-MR).

About Naval Anti-Ship Missile–Medium Range (NASM–MR)

It is a subsonic, sea-skimming anti-ship missile.
It is being developed by the Defence Research and Development Organisation (DRDO) for the Indian Navy for use against small- to medium-sized targets such as frigates, corvettes, and destroyers.
It will have different versions, including ship-launched, air-launched, and submarine-launched variants.
The missile complements the existing Naval Anti-Ship Missile-Short Range (NASM-SR), which was successfully tested earlier from a helicopter platform.
Together, these systems provide layered strike options for the Navy, enabling both close-range and medium-range engagements against hostile warships.
Features:
- It is powered by a Small Gas Turbine Jet Engine (SGTJE).
- This all-weather missile has a strike range of up to 350 km.
- It has a warhead weighing more than 200 kilograms.
- It has an advanced guidance system, which reportedly combines an active radar seeker with an imaging infrared (IR) seeker.

Successful Trials of Multi-Layered Ballistic Missile Defence (BMD) system

The latest tests involved advanced interceptor systems developed under Phase II of the BMD programme, including the AD-series interceptors.
These systems have been designed to engage and neutralise advanced, high-speed threats such as intermediate-range ballistic missiles (IRBMs) and ICBMs capable of travelling up to the 5,000-km class.
The AD-1 endo-atmospheric interceptor has been designed to intercept targets within the Earth's atmosphere during the terminal phase of their flight.
- Propelled by a two-stage solid motor, it utilises advanced navigation and guidance algorithms to track and destroy fast-moving missiles as well as slower-moving aircraft.
Similarly, the AD-2 interceptor has been designed to intercept incoming missiles at much higher altitudes, beyond the Earth's atmosphere during their mid-course flight phase.
- This allows early interception in space, destroying threats before they can re-enter and target specific regions.
Both missiles are highly manoeuvrable and capable of hypersonic speeds ranging from Mach 6 to Mach 7, enabling them to intercept fast-moving ballistic targets.
These tests have put the country in the elite group of nations having BMD capability to engage up to ICBMs.
