Earth’s ‘green lung’ rainforests take center stage at talks in Gabon

The sixth annual One Planet Summit begins on Wednesday, with the fate of forests at the top of the agenda. Politicians, scientists and NGOs will meet in Libreville, Gabon, to discuss the future of rainforests in the Congo basin, Southeast Asia and the Amazon basin – and whether countries in the Global North should finance the preservation of the Earth’s “green lungs”.

French President Emmanuel Macron will preside over the two-day conference from Libreville in the heart of Africa’s “green lung”: more than 200 million hectares of forest spread over six countries, filled with biodiverse species found nowhere else in the world.

Should we bring back the dodo? De-extinction is a feel-good story, but these high-tech replacements aren’t really ‘resurrecting’ species

It’s no secret that human activities have put many of this planet’s inhabitants in danger. Extinctions are happening at a dramatically faster rate than they have over the past tens of millions of years. An estimated quarter of all species on Earth are at risk of being lost, many within decades.

What can scientists possibly do to stop that trend? For some, the answer is to “de-extinct.”

A ‘recently discovered’ whale feeding strategy has turned up in 2,000-year-old texts about fearsome sea monsters

In 2011, researchers observed a previously unknown feeding strategy in whales, now called tread-water feeding or trap-feeding. It was thought to be a new technique developed by specific whale communities.

Trap-feeding is one of several whale feeding strategies first recorded in recent decades, including lunge feeding, lobtail feeding and the dramatic bubble-net feeding, when whales create a fence of bubbles to herd krill or fish together.

Signs of Everglades recovery emerge. Long way to go but ‘trending in the right direction’

After decades of planning and pleading for political support and dollars to restore the Everglades, there are growing signs that the massive multibillion-dollar effort is beginning to “get the water right.” That’s long been the measure of success for the federal and state agencies tasked with the job. The goal sounds deceptively simple but is immensely complicated, requiring not just sending more water through the parched southern Everglades and into Florida Bay but ensuring that bordering communities aren’t flooded in the process. The most encouraging indicator: Wildlife, the measuring sticks...

One easy way to fight antibiotic resistance? Good hand hygiene

Can washing your hands help stop the evolution of antibiotic resistance? Mathematically, it’s possible.

Antibiotics save lives by killing bacteria that cause infections. But antibiotics don’t just kill infection-causing bacteria or stay in the area of the body where the infection is occurring. Instead, antibiotics spread across the body and inhibit or kill any sensitive bacteria they encounter.

Adults who were sexually abused in childhood have lower gray matter volume in specific brain region, study finds

A study in South Korea found that people who survived childhood sexual abuse and currently suffer from major depression disorder had significantly lower gray matter volume in the right middle occipital gyrus region of the brain. Their grey matter volume in this specific region was lower than both healthy adults and people suffering from depression who did not experience sexual abuse in childhood. The study was published in Psychiatry Research. Abuse in childhood has been shown to be associated with a number of negative outcomes in adulthood. These include negative perceptions of oneself, easil...

New study disputes the birth order theory that later-born are “born to rebel”

Those born later in a family may not be “born to rebel,” as posited by some researchers. A new study published in Personality and Individual Differences found later-born individuals are not more likely to have tattoos, and although they do test higher in measures of risk-taking and sensation seeking, they did not demonstrate a higher need for uniqueness. The study did not find good evidence for the “born to rebel” hypothesis, leaving another birth order theory open to critique. The “born to rebel” hypothesis, developed by Frank Sulloway in 1996, suggests that later-born children tend to develo...

New species found in ‘magical ecosystem’ in Ecuador gets name inspired by Tolkien

Often referred to as the father of modern fantasy, author J.R.R. Tolkien created a larger than life world inhabited by goblins, giant spiders and fire-breathing dragons. His namesake has now been given to a decidedly less terrifying creature, a l Zoo Keys. “It would seem that it lives in a universe of fantasies, like those created by Tolkien,” the researchers wrote in a news release. “The truth is that the tropical Andes are magical ecosystems where some of the most wonderful species of flora, funga, and fauna in the world are present.” Upon finding the frog, researchers named it Hyloscirtus t...

Can eating poppy seeds affect drug test results? An addiction and pain medicine specialist explains

The U.S. Defense Department issued a memo on Feb. 17, 2023, warning service members to avoid eating poppy seeds because doing so may result in a positive urine test for the opiate codeine. Addiction and pain medicine specialist Gary Reisfield explains what affects the opiate content of poppy seeds and how they could influence drug tests.

What are poppy seeds?

Poppy seeds come from a species of poppy plant called Papaver somniferum. “Somniferum” is Latin for “sleep-bringing,” which hints that it might contain opiates – powerful compounds that depress the central nervous system and can induce drowsiness and sleep.

Habitual checking of social media linked to altered brain development in young adolescents

New neuroimaging research provides evidence that the frequency of checking social media during adolescent might influence how the brains of teenagers develop. The findings, published in JAMA Pediatrics, indicate the the use of social media is related to developmental changes in neural sensitivity to anticipation of social rewards and punishments. “We were interested to see how young adolescents’ social media use behaviors may relate to the trajectory of their brain development over time,” said study author Kara A. Fox, a PhD student at the University of North Carolina at Chapel Hill. “The cons...

Extinct-in-the-wild species in conservation limbo

For species classified as "extinct in the wild", the zoos and botanical gardens where their fates hang by a thread are as often anterooms to oblivion as gateways to recovery, new research has shown.

Re-wilding what are often single-digit populations faces the same challenges that pushed these species to the cusp of extinction in the first place, including a lack of genetic diversity. But without conservation efforts, experts say, chances of these species surviving would be even smaller.

When and where can I see wildflowers in Northern California? Here’s what to expect this season

A generous amount of water dropped over Northern California this winter, and rolling green hills adorned with wildflower blooms are anticipated throughout the Golden State. Previous superblooms, or an unusually high number of wildflowers, have drawn large crowds to California state parks. This year “the wildflower bloom is expected to be good to better-than-average” in parts of California, said Jorge Moreno, a spokesman for the California Department of Parks and Recreation, in an email to The Bee. Wildflower season typically starts at the end of February and lasts until early May. In the Sierr...
