Researchers uncover critical pattern behind species decline: 'We need to ... start addressing the root cause'
A University of Cambridge research team analyzed data to uncover the effectiveness of conservation efforts — and the results were positive, but more needs to be done.
The research, as Phys.org shared via a release from the university, utilized IUCN Red List data to assess conservation efforts' impacts. The Red List of Threatened Species is the International Union for Conservation of Nature's globally recognized list for assessing extinction risks for various species of animals, plants, and fungi.
According to the Red List, more than 47,000 species are threatened with extinction. And there are thousands of species yet to be assessed.
The team found that nearly all instances of a species' endangerment decreasing could be associated with conservation efforts. "It's a strong signal that conservation works," said lead author Ashley Simkins, a doctoral student in the Department of Zoology.
The results show that conservation is crucial to saving species on the edge. Even as the world's biodiversity decreases, mostly because of human activity, conservation efforts work.
Species that have been brought back from the brink of extinction include humpback whales, blue whales, and Iberian lynxes. But many more populations are declining.
Biodiversity is essential for Earth's health. Each ecosystem, whether in your neighborhood or the heart of the Amazon, relies on diversity to thrive. When one species suffers or disappears, it disrupts the delicate balance of that ecosystem. This domino effect accelerates rising global temperatures by weakening native species and interrupting important processes such as pollination.
Without these species and processes, air quality worsens, the human food supply is put at risk, diseases spread easily, extreme weather swings more wildly, and more. Saving as many species as possible is crucial.
"Humans have gotten pretty good at what could be considered 'A&E' conservation — focusing on species at very high risk of extinction," Simkins explained. "... We need to move beyond treating the symptoms of biodiversity loss and start addressing the root causes."
Simkins highlights how unique conservation strategies can benefit nature and humanity. There's no one-size-fits-all solution for helping endangered species. We must be creative in our conservation efforts and focus on prevention just as much as emergency recovery so that every living thing, including humans, can flourish.

AI helped design an innovative new cancer treatment plan
If you purchase an independently reviewed product or service through a link on our website, BGR may receive an affiliate commission. Researchers may have come up with an interesting new treatment for cancer by talking to AI. According to a paper published this month, a research team led by the University of Cambridge turned to an 'AI scientist' powered by GPT-4 to help create a new AI-designed cancer treatment plan. The kicker? It only uses widely available drugs that have nothing to do with treating cancer. The researchers started by taking all of the data they had regarding popular drugs used to treat high cholesterol and alcohol dependence to look for hidden patterns that could point toward new cancer drug options. They prompted GPT-4 to identify combinations of the drugs that could possibly have a significant impact on breast cancer cells.

The drugs that the AI was prompted to look for were also meant to be widely available, affordable, and already approved by regulators. Considering how many different types of cancer treatment options we've seen in recent years, this approach makes a lot of sense. It also opened some new doors, according to the researcher's findings, which are published in the Journal of Royal Society Interface. We've seen a huge increase in researchers and doctors turning to AI to try to come up with new treatment options for old problems, including an AI that can identify autism. So it isn't that surprising to see researchers once more turning to AI to help speed up scientific progress. It seems to have worked, too. According to the findings, the researchers tested the combinations suggested by the GPT-4 'scientist' and found that three of the 12 combinations worked better than current breast cancer drugs. They then fed that information back to the AI, which created four more combinations, three of which also showed a lot of promise. Of course, relying wholly on AI-designed cancer treatment plans isn't something doctors are likely to do immediately. More trials and research are needed to fully test the efficiency of these drug combinations. Testing will also need to be done to ensure there aren't any adverse side effects from combining these drugs over extended periods of time. But for those fighting cancer right now, research like this is promising and could one day help scientists find even better treatment options. And even if the AI hallucinates, the information it gives may spark a new idea that scientists hadn't thought of before. AI will never replace doctors, no matter how hard Google and others push for a future involving AI doctors. But by relying on AI to speed up research, scientists can potentially unlock new options they might not otherwise find for decades to come.

This ‘Tower of Worms' Is a Squirming Superorganism
When food runs out, certain tiny roundworms, barely visible to the naked eye, crawl toward one another and build living, wriggling towers that move as one superorganism. For the first time, we've caught them doing that in nature on video. Scientists spent months pointing their digital microscope at rotting apples and pears to finally catch a glimpse of these living towers formed by Caenorhabditis roundworms in an orchard that is just downhill from the Max Planck Institute of Animal Behavior's location in Konstanz, Germany. 'It wasn't that hard to find. It's just the people didn't have the interest or time or funding for this kind of research,' says biologist Daniela Perez, lead author of the study. Perez and her team at the Max Planck Institute of Animal Behavior then studied this behavior in a laboratory to learn more. To spur the towering, they placed groups of Caenorhabditis elegans in a dish without food, alongside a toothbrush bristle that could work as a scaffold. Dozens of worms quickly climbed on top of the bristle and one another to form a structure that moved in an eerily coordinated manner. The tower responded to the touch of a glass pipe by attempting to latch onto it; it stretched to bridge the gap between the bottom of the dish and its lid; and it even waved its tip around to probe the surrounding environment. The results were published Thursday in Current Biology. [Sign up for Today in Science, a free daily newsletter] Researchers had previously observed this towering in the lab but didn't know that it was an actual survival strategy in the wild. 'Discovering [this behavior] in wild populations is really important as it shows this is a part of how these animals live and not just a lab artifact,' says William Schafer, a geneticist at the University of Cambridge, who studies C. elegans and was not involved in the study. Why do the worms do this? The researchers think towering helps worms set out to find richer food sources. When resources are limited, 'it probably makes sense for microscopic organisms to cooperate for dispersing by forming something bigger,' says the study's senior author Serena Ding. The towers could allow some of their members to reach new places or to hitchhike on other organisms such as fruit flies. The bigger question is how the worms communicate within the towers. If the worms on top latch onto a fly, how do those at the bottom know to detach from where they're anchored? They could communicate chemically through pheromones and mechanically through movement patterns, Schafer suggests. Perez says her team plans to test this next. 'Every time we have a meeting, we end up with 10 new project ideas,' she says. 'There are so many directions we can take this.'
