The rhino population across the world has increased slightly but so have the killings, mostly in South Africa, as poaching fed by huge demand for rhino horns remains a top threat, conservationists said in a new report.

The number of white rhinos increased from 15,942 in 2022 to 17,464 in 2023, but the black and greater one-horned rhino stayed the same, according to the report published by the International Rhino Foundation ahead of Sunday’s World Rhino Day.

Another subspecies, the northern white rhino, is technically extinct with only two females being kept in a secure private conservancy in Kenya, known as Ol Pejeta. A trial is ongoing to develop embryos in the lab from an egg and sperm previously collected from white rhinos and transferring it into a surrogate female black rhino, The AP reported.

A total of 586 rhinos were killed in Africa in 2023, most of them in South Africa — which has the highest population of rhinos at an estimated 16,056. The killings increased from 551 reported in 2022, according to the International Union for Conservation of Nature.

Rhinos face various environmental threats like habitat loss due to development and climate change but poaching, based on the belief that their horns have medicinal uses, remains the top threat.

Philip Muruthi, the vice president for species conservation at the Africa Wildlife Foundation, said protection has played a big role in increasing rhino population. In Kenya, their numbers rose from 380 in 1986 to 1,000 last year, he said. “Why has that happened? Because the rhinos were brought into sanctuaries and were protected.”

Muruthi advocates for a campaign that will end the demand for rhino horn as well as adoption of new technology in tracking and monitoring rhinos for their protection while also educating communities where they live on the benefits of rhinos to the ecosystem and the economy.

Known as mega herbivores that mow the parks and create inroads for other herbivores, rhinos are also good for establishing forests by ingesting seeds and spreading them across the parks in their dung.

Murithi lamented that the northern white rhino — whose only two females are left in the world — should have never gotten so close to the brink of extinction.

“Don’t get the numbers to where it’s very expensive to recover and we are not even sure that it will happen,” he said.

The body of the last male northern white rhino – named Sudan – that died in 2018 has been preserved and displayed at the Museums of Kenya in Nairobi.

A research scientist and curator of mammals at the museum, Bernard Agwanda, said preserving Sudan will tell the story of how the species lived among humans and why conservation is important.

“So we expect that the northern white rhino behind us here is going to live for one or two centuries to be able to tell its story for generations to come,” he said.

Brazilian scientists have identified a new species of giant dinosaur with ties to a similar animal found in Spain, reinforcing knowledge that land routes once connected parts of South America, Africa and Europe about 120 million years ago.

Named Dasosaurus tocantinensis, the species is one of the biggest found in the South American country and was described this month in the Journal of Systematic Palaeontology, Reuters reported.

The fossils were uncovered in 2021 at a site hosting infrastructure works near Davinopolis, in Brazil's northeastern state of Maranhao, and the research was led by Elver Mayer of the Federal University of the Sao Francisco Valley.

The remains include a femur measuring about 1.5 meters (59 inches), which helped researchers estimate the animal stretched roughly 20 meters long.

"As the excavation progressed over the days, we began to see the evidence of that huge bone, which is the femur," said Leonardo Kerber, a paleontologist at the Federal University of Santa Maria (UFSM) who contributed to the research.

"This indicates it was a very large dinosaur. Today we know Dasosaurus is among the biggest dinosaurs ever found in Brazil," he noted.

According to UFSM, analysis indicated the species is the closest known relative of Garumbatitan morellensis, a dinosaur described in Spain.

Their lineage was European and may have dispersed into what is now South America roughly 130 million years ago, likely via northern Africa, before the Atlantic fully opened, the university said.

Dasosaurus tocantinensis's name combines references to the region where the dinosaur was found, including the Tocantins River, a major waterway whose eastern margins lie near the fossil site.

The German philosopher Jurgen Habermas has died, a spokesperson for his publishing house, Suhrkamp Verlag, told AFP on Saturday.

He died at the age of 96 in Starnberg, in southern Germany, she said, citing information from the family of the politically engaged theorist.

Habermas was considered the most influential German philosopher of his generation, involved in all the major postwar debates and seeing a united Europe, in his view, as the only remedy for the rise of nationalism, AFP reported.

In his later years, he devoted himself to promoting a federal European project and prevent the continent from falling, as it did in the 20th century, into nationalist rivalries.

Throughout his life, Habermas linked philosophy and politics, thought and action.

After serving as the voice of German student protest in the 1960s, he became its target thirty years later while warning of the risks of "left-wing fascism".

In 1989, he criticised the terms of German reunification, guided essentially by the demands of the market, and which made "the Deutsche mark its standard."

Born on June 18, 1929 in Duesseldorf, Habermas had been enrolled in the Hitler Youth, but he was too young to have taken an active part in the war. As a teenager, he was deeply marked by the collapse of Nazism.

Research Reveals Decades-Long Silverpit Crater Triggered by Tsunami 40 Million Years Ago

A long-running dispute about the origin of a North Sea crater has finally been settled, as new research finds a massive asteroid hit the water and triggered a towering tsunami millions of years ago.

Scientists have found that the Silverpit Crater – which lies around 700 meters beneath the southern North Sea seabed, roughly 80 miles off the coast of Yorkshire – was formed when an asteroid or comet struck the region roughly 43 to 46 million years ago, sparking a 330 feet tsunami.

Since geologists first identified the formation in 2002, the 3km-wide crater and its surrounding ring of circular faults spanning about 20 km have sparked intense debate, according to The Independent.

But researchers say their new study marks the clearest evidence yet that the structure is one of Earth’s rare impact craters.

This confirmation places it in the same category as well-known structures such as the Chicxulub Crater in Mexico, which is linked to the dinosaur mass extinction.

The team used computer modelling and analyzed newly available seismic imaging and microscopic geological samples taken from beneath the seabed.

Dr. Uisdean Nicholson, a sedimentologist in Heriot-Watt University’s School of Energy, Geoscience, Infrastructure and Society, who led the investigation, said: “New seismic imaging has given us an unprecedented look at the crater.”

He said samples from an oil well in the area also revealed rare ‘shocked’ quartz and feldspar crystals at the same depth as the crater floor.

“We were exceptionally lucky to find these – a real ‘needle-in-a-haystack’ effort. These prove the impact crater hypothesis beyond doubt, because they have a fabric that can only be created by extreme shock pressures,” said Nicholson.

The scientists say these microscopic minerals form only under the extreme pressures generated during asteroid impacts, providing strong confirmation of the event.

Early research proposed that the feature was created by a high-speed asteroid impact. Supporters of that idea pointed to its round shape, central peak, and surrounding concentric faults, which are often seen in known impact craters.

But other scientists suggested different explanations. Some proposed that underground salt movement distorted the rock layers and created the structure.

Others argued that volcanic activity may have caused the seabed to collapse.

In 2009, geologists even voted on the issue. According to a report in the December 2009 issue of Geoscientist magazine, most participants rejected the asteroid impact explanation at the time.

The latest findings, published in the journal Nature Communications and funded by the Natural Environment Research Council (NERC), now appear to overturn that conclusion.

Dr. Nicholson said: “Our evidence shows that a 160-meter-wide asteroid hit the seabed at a low angle from the west.”

“Within minutes, it created a 1.5 km high curtain of rock and water that then collapsed into the sea, creating a tsunami over 100 meters high.”

The impact would have produced a violent explosion at the seafloor and sent enormous waves spreading across the region.

Professor Gareth Collins, of Imperial College London, who attended the 2009 debate about the crater’s origin and contributed to the new research, said the researchers have “finally found the silver bullet” to end the debate.

He said: “I always thought that the impact hypothesis was the simplest explanation and most consistent with the observations.”

“It is very rewarding to have finally found the silver bullet. We can now get on with the exciting job of using the amazing new data to learn more about how impacts shape planets below the surface, which is really hard to do on other planets,” Collins added.

Dr. Nicholson also expressed his excitement about using the new findings for further research into asteroids.

“Silverpit is a rare and exceptionally preserved hypervelocity impact crater,” he said.

“These are rare because the Earth is such a dynamic planet – plate tectonics and erosion destroy almost all traces of most of these events.”
