Karnataka: Expert committee finds excess use of oxygen to treat COVID-19 patients

Mangaluru, Dec 7: A rare bamboo shrimp has been rediscovered on mainland India more than 70 years after it was last reported, confirming for the first time the presence of Atyopsis spinipes in the country. The find was made by researchers from the Centre for Climate Change Studies at Sathyabama Institute of Science and Technology, Chennai, during surveys in Karnataka and Odisha.

The team — shrimp expert Dr S Prakash, PhD scholar K Kunjulakshmi, and Mangaluru-based researcher Maclean Antony Santos — combined field surveys, ecological assessments and DNA analysis to identify the elusive species. Their findings, published in Zootaxa, resolve decades of taxonomic confusion stemming from a 1951 report that misidentified the species as Atyopsis moluccensis without strong evidence.

The shrimp has now been confirmed at two locations: the Mulki–Pavanje estuary near Mangaluru and the Kuakhai River in Bhubaneswar. Historical specimens from the Andaman Islands, previously labelled as A. moluccensis, were also found to be misidentified and actually belong to A. spinipes.

The rediscovery began after an aquarium hobbyist in Odisha spotted a shrimp in 2022, prompting systematic surveys across Udupi, Karwar and Mangaluru. Four female specimens were collected in Mulki and one in Odisha, all genetically matching.

Researchers warn the species may exist in very small, vulnerable populations as freshwater habitats face increasing pressure from pollution, sand mining and infrastructure development. All verified specimens have been deposited with the Zoological Survey of India for future reference.

Mangaluru, Dec 16: The Mangaluru City police have significantly escalated their campaign against drug trafficking, arresting 25 individuals and booking 12 cases under the Narcotic Drugs and Psychotropic Substances (NDPS) Act between November 30 and December 13. The crackdown resulted in the seizure of a substantial quantity of illicit substances, including 685.6 grams of MDMA and 1.5 kg of ganja.

The success of this recent drive has been significantly boosted by the city’s innovative, QR code-based anonymous reporting system.

"The anonymous reporting system has received an encouraging response. Several recent arrests were made based on inputs received through this system, helping police tighten the noose around drug peddlers," said the City Police Commissioner.

The latest arrests contribute to a robust year-to-date record, underscoring the police's relentless commitment to combating the drug menace.

Up to December 14 this year, the police have registered a total of 107 cases of drug peddling, leading to the arrest of 219 peddlers. Furthermore, they have booked 562 cases of drug consumption, resulting in the arrest of 671 individuals.

The scale of the seizure for the year reflects the magnitude of the problem being tackled: police have seized 320.6 kg of ganja worth ₹88.7 lakh and 1.4 kg of MDMA valued at ₹1.2 crore. Other significant seizures include hydro-weed ganja worth ₹94.7 lakh and cocaine worth ₹1.9 lakh, among others.

The Commissioner emphasized a policy of rigorous enforcement: "We ensure that peddlers are caught red-handed so that they cannot later dispute the case or claim innocence."

To counter the rising trend of substance abuse among youth, the Mangaluru City police have rolled out uniform guidelines for random drug testing across educational institutions.

As part of the drive, tests were conducted in approximately 100 institutions, screening an estimated 5,500 to 6,000 students in the first phase. 20 students tested positive for drug consumption during the initial screening.

Students who tested positive have been provided counselling and are scheduled for re-testing in the second quarter. The testing will also be expanded to students not covered in the first phase. In a move to ensure strict implementation, police personnel were deployed in mufti in some institutions. Reiterating a zero-tolerance stance, the Commissioner confirmed that random testing will continue, and colleges have also been instructed to conduct drug tests at the time of admission to deter substance abuse from an early stage.

At least seven elephants were killed and one calf injured after a herd collided with the Sairang-New Delhi Rajdhani Express in Assam's Hojai on Saturday morning, leading to disruption of rail services. 

The Sairang-New Delhi Rajdhani Express struck a herd of elephants, resulting in the derailment of the locomotive and five coaches. No passenger casualties or injuries were reported, officials said.

The New Delhi-bound train met with the accident around 2.17 am, PTI reported. The Sairang-New Delhi Rajdhani Express connects Mizoram's Sairang (near Aizawl) to Anand Vihar Terminal (Delhi). 

Railway has issued helpline numbers at the Guwahati Railway Station:-

•    0361-2731621
•    0361-2731622
•    0361-2731623

The accident site is located about 126 km from Guwahati. Following the incident, accident relief trains and railway officials rushed to the spot to initiate rescue operations.

Train Services Disrupted

Sources said that due to the derailment and elephant body parts scattered on the tracks, train services to Upper Assam and other parts of the Northeast were affected.

Passengers from the affected coaches were temporarily accommodated in vacant berths available in other coaches of the train. Once the train reaches Guwahati, additional coaches will be attached to accommodate all passengers, after which the train will resume its onward journey.

The incident occurred at a location that is not a designated elephant corridor. The loco pilot, upon spotting the herd on the tracks, applied emergency brakes. Despite this, the elephants dashed into the train, leading to the collision and derailment.

Last month, an elephant was killed after being hit by a train in Dhupguri in West Bengal's Jalpaiguri district. The incident took place on November 30. 

The adult elephant was killed on the spot, and a calf was discovered lying injured beside the tracks. 

Over 70 Elephants Killed In Train Collisions Over Last 5 Years

At least 79 elephants have died in train collisions across the country in the last five years, the Environment Ministry had informed Parliament in August.

In a written reply in the Lok Sabha, Minister of State for Environment Kirti Vardhan Singh had said the figure is based on reports from state governments and Union Territory administrations for the period 2020-21 to 2024-25.

He said that the ministry does not maintain consolidated data on the deaths of other wild animals on railway tracks, including in designated elephant corridors.

Singh confirmed that three elephants, including a mother and her calf, were killed on July 18 this year after being hit by a speeding express train on the Kharagpur-Tatanagar section in West Bengal's Paschim Midnapore district. The incident took place near Banstala between Jhargram and Banstala stations.

The minister said several measures have been taken jointly by the Environment Ministry and the Railways to prevent such accidents.

These include imposing speed restrictions in elephant habitats, pilot projects such as seismic sensor-based detection of elephants near tracks and construction of underpasses, ramps and fencing at vulnerable points.

The Wildlife Institute of India, in consultation with the ministry and other stakeholders, has also issued guidelines titled 'Eco-friendly Measures to Mitigate Impacts of Linear Infrastructure' to help agencies design railways and other projects in ways that reduce human-animal conflicts.

Singh added that capacity-building workshops were conducted for railway officials at the Wildlife Institute of India in 2023 and 2024 to raise awareness on elephant conservation and protection.

A detailed report titled 'Suggested Measures to Mitigate Elephant & Other Wildlife Train Collisions on Vulnerable Railway Stretches in India' had also been prepared after surveys across 127 railway stretches covering 3,452 km.

Of these, 77 stretches spanning 1,965 km in 14 states were prioritised for mitigation, with site-specific interventions suggested.
