When Zoo Elephants Are Rewilded in Africa, Here’s How Good Their Coping Skills Are

New research shows that elephants develop successful coping mechanisms when returning to the wild from human captivity.

In fact, the team found that “rewilded” elephants can fit quite well within wildlife systems and readapt—even after long-term captivity.

For the new study, a team from the Elephant Reintegration Trust of South Africa examined the behavioral and physiological responses of 11 formerly-captive elephants which had been released onto four different reserves.

For five years each elephant was observed for three weeks at a time at least once annually.

The team looked for indicators that the elephants might be uncomfortable in their wild surroundings and for behaviors that might be “hold-overs” from their time in captivity, such as conflict or confrontation.

The findings showed that, overall, rewilded elephants behaved “very similarly” to their wild neighbors.

Fecal samples collected to test for signs of metabolic stress showed levels within the normal range for wild elephants.

“What I found most fascinating was watching elephants that had spent decades in captivity adapt so successfully to life in the wild,” said co-author Tenisha Roos.

“Seeing them respond to their environment and function much like wild elephants was truly awe-inspiring and a powerful reminder of their remarkable resilience, adaptability, and behavioral flexibility.”

The differences may reflect their previous captive experiences, social circumstances, environmental conditions, and tourism or management pressures, according to the research team.

They say their findings, published in the journal PLOS One, show that rewilded elephants behave “very similarly” to their wild counterparts, despite some consistent differences—suggesting that they have adapted well to their return to wild habitats.

The research team also noted a high degree of variability in behavior between individual rewilded elephants, but that might be related to each animal’s personality.

Each elephant likely found their own unique ways to cope with their relocation.

The 11 animals in the study represent more than 50% of the rewilded elephant population across South Africa so far.

“While a few elephants showed slightly elevated stress biomarkers, all values remained within the normal range for wild populations, indicating successful adaptation—with no evidence of chronic stress.”

Co-author Tammy Eggeling said: “Although previously-captive elephants may carry the memories of confinement, our research has shown that, when given the opportunity, they can leave that past behind.

“They are able to learn new skills, adapt to unfamiliar environments, and ultimately thrive as wild elephants.”

Co-author Brett Mitchell added: “The data from this project show that when captive elephants are rewilded and given the opportunity, they can regain full autonomy and re-establish natural patterns of movement and behavior.“Through this research, we are also seeing that rewilded elephants can make a meaningful contribution to the conservation of their species.” When Zoo Elephants Are Rewilded in Africa, Here’s How Good Their Coping Skills Are

EV Charging Answer: Quantum Technology Will Cut Time it Takes to Charge Electric Cars to Just 9 Seconds

Institute for Basic Science

Scientists in South Korea have proven that a new technology will cut the time it takes to charge electric cars to just nine seconds, allowing EV owners to ‘fill up’ faster than their gasoline counterparts.

And even those plugging-in at home will have the time slashed from 10 hours to three minutes.

The new device uses the laws of quantum physics to power all of a battery’s cells at once—instead of one at a time—so recharging takes no longer than filling up at the pump.

Electric cars were rarely seen on the roads 10 years ago, but millions are now being sold every year and it has become one of the fastest growing industries, but even the fastest superchargers need around 20 to 40 minutes to power their car.

Scientists at the Institute for Basic Science (IBS) in South Korea have come up with a solution. Co-author Dr. Dario Rosa said the consequences could be far-reaching.

“Quantum charging could go well beyond electric cars and consumer electronics. For example, it may find key uses in future fusion power plants, which require large amounts of energy to be charged and discharged in an instant.”

The concept of a “quantum battery” was first proposed in a seminal paper published by Alicki and Fannes in 2012. It was theorized that quantum resources, such as entanglement, can be used to vastly speed up battery charging.

The researchers used quantum mechanics to model their super fast charging station with calculations of the charging speed showing that a typical electric vehicle with a battery containing around 200 cells would recharge 200 times faster.

Current collective charging is not possible in classical batteries, where the cells are charged in parallel, independently of one another.

“This is particularly exciting as modern large-capacity batteries can contain numerous cells.”

The group went further to provide an explicit way of designing such batteries.

This means charging times could be cut from 10 hours to three minutes at home and from around 30 minutes to just a few seconds at stations.

Co-author Dr Dominik Šafránek said, “Of course, quantum technologies are still in their infancy and there is a long way to go before these methods can be implemented in practice.”

“Research findings such as these, however, create a promising direction and can incentivize the funding agencies and businesses to further invest in these technologies.

“If employed, it is believed that quantum batteries would completely revolutionize the way we use energy and take us a step closer to our sustainable future.”

The findings were published in the February 8 edition of the journal Physical Review Letters. [GNN updated the earlier broken link.] EV Charging Answer: Quantum Technology Will Cut Time it Takes to Charge Electric Cars to Just 9 Seconds
