Washington, Apr 10: Scientists released the much-awaited first direct image of a massive black hole at the centre of Messier 87, a galaxy which is about 54 million light-years away, at the National Press Club here on Wednesday. 

The image has been taken by the Event Horizon Telescope (EHT), which is a network of 10 radio telescopes spread across the planet, according to The Washington Post. The telescope functioned as if it is a single receiver, tuned to high-frequency radio waves, to take the image. 

The picture - released at six simultaneous news conferences on Wednesday - shows the event horizon, which is the boundary between light and dark around a black hole. A doughnut-like body can be seen in the portrait, which scientists say is the dark silhouette of the black hole against the hot, glowing material that surrounds it. 

"We are able to image one more object in the universe that ... at one point people thought could not be possible. It hits that human explorer spirit. We got another look into the unknown," Feryal Ozel, a member of the science council for the EHT said, calling the occasion her career's highlight.
 
The shape of the black hole matches what theorists had predicted ever since they started wrestling with Albert Einstein, General Theory of Relatively over a hundred years ago, reports The Washington Post. 

The European Commission hailed the occasion as a "paradigm shift" adding, "This major scientific achievement marks a paradigm shift in our understanding of black holes, confirms the predictions of Albert Einstein's General Theory of Relativity and opens up new lines of enquiry into our universe."

Mangaluru: The Karnataka Government Polytechnic (KPT), Mangaluru, has achieved autonomous status from the All India Council for Technical Education (AICTE), becoming the first government polytechnic in the country to receive such recognition in its 78-year history. The status was granted by AICTE, New Delhi, and subsequently approved by the Karnataka Board of Technical Education in October last year.

Officials said the autonomy was conferred a few months ago. Until recently, AICTE extended autonomous status only to engineering colleges, excluding diploma institutions. However, with a renewed national focus on skill development, several government polytechnics across India have now been granted autonomy.

KPT, the second-largest polytechnic in Karnataka, was established in 1946 with four branches and has since expanded to offer eight diploma programmes, including computer science and polymer technology. The institution is spread across a 19-acre campus.

Ravindra M Keni, the first dean of the institution, told The Times of India that AICTE had proposed autonomous status for polytechnic institutions that are over 25 years old. “Many colleges applied. In the first round, 100 institutions were shortlisted, which was further narrowed down to 15 in the second round. We have already completed one semester after becoming an autonomous institution,” he said. He added that nearly 500 students are admitted annually across eight three-year diploma courses.

Explaining the factors that helped KPT secure autonomy, Keni said the institution has consistently recorded 100 per cent admissions and placements for its graduates. He also noted its strong performance in sports, with the college emerging champions for 12 consecutive years, along with active student participation in NCC and NSS activities.

Autonomous status allows KPT to design industry-oriented curricula, conduct examinations, prepare question papers, and manage academic documentation independently. The institution can also directly collaborate with industries and receive priority funding from AICTE or the Ministry of Education. While academic autonomy has been granted, financial control will continue to rest with the state government.

“There will be separate committees for examinations, question paper setting, boards of studies, and boards of examiners. The institution will now have the freedom to conduct admissions without government notifications and issue its own marks cards,” Keni said, adding that new academic initiatives would be planned after a year of functioning under the autonomous framework.

Bengaluru: Following reports of fresh Nipah virus (NiV) cases in West Bengal and heightened vigilance across parts of Southeast Asia, the Karnataka Health Department has placed the state on high alert and activated emergency preparedness protocols.

Health officials said enhanced surveillance measures have been initiated after two healthcare workers in Barasat, West Bengal, tested positive for the virus earlier this month. While no cases have been reported in Karnataka so far, authorities said the state’s past exposure to Nipah outbreaks and high inter-state mobility warranted preventive action.

Officials have directed district health teams to intensify monitoring, particularly at hospitals and points of entry, and to ensure early detection and isolation of suspected cases.

High Mortality Virus with Multiple Transmission Routes

Nipah virus is a zoonotic disease that can spread from animals to humans and has a reported fatality rate ranging between 60 and 75 per cent. Fruit bats, also known as flying foxes, are the natural reservoirs of the virus and can transmit it by contaminating food sources with saliva or urine.

Known modes of transmission include:

•    Contaminated food: Consumption of fruits partially eaten by bats or raw date-palm sap
•    Animal contact: Exposure to infected pigs or other animals
•    Human-to-human transmission: Close contact with body fluids of infected persons, particularly in healthcare settings

Symptoms and Disease Progression

The incubation period typically ranges from 4 to 14 days, though delayed onset has also been reported. Early symptoms often resemble common viral infections, making prompt clinical suspicion critical.

•    Initial symptoms: Fever, headache, body aches, fatigue, sore throat
•    Progressive symptoms: Drowsiness, disorientation, altered mental state
•    Severe stage: Seizures, neck stiffness and acute encephalitis, which can rapidly progress to coma

Public Health Advisory

The Health Department has issued precautionary guidelines urging the public to adopt risk-avoidance practices to prevent any local spillover.

Do’s
•    Wash fruits thoroughly before consumption
•    Drink boiled and cooled water
•    Use protective equipment while handling livestock
•    Maintain strict hand hygiene

Don’ts
•    Avoid fruits found on the ground or showing bite marks
•    Do not consume beverages made from raw tree sap, including toddy
•    Avoid areas with dense bat populations
•    Do not handle sick or dead animals

Preparedness Measures

Officials confirmed that isolation wards are being readied in major government hospitals and that medical staff are being sensitised to identify early warning signs.

“There is no cause for panic, but there is a need for heightened vigilance,” a senior health official said, adding that there is currently no approved vaccine or specific antiviral treatment for Nipah, and care remains largely supportive.
