This month: Some regions of the deep ocean contain vast amounts of key minerals, like cobalt and nickel, that are needed to power clean energy technologies. But some scientists warn that mining them could have tremendous consequences, not just for underwater ecosystems, but for the planet as a whole.

This month: Twenty-six years after the end of the Bosnian War, farmers in Livno are once again making cheese the traditional way, grazing herds of sheep on the wide-open plains. The animals' return is restoring natural wetlands, leading to cascading impacts on the environment and the economy.

For scientists who come from abroad to live and work in America, accents can be personal. It's discouraging to be misunderstood, even when they think they’re speaking clearly. Sometimes, it could even be a career liability. Is the problem the accent, or those on the receiving end?

Residents of Lebanon's Beqaa Valley say pollution in the Litani River is responsible for a host of chronic health problems. While a causal link is hard to prove, cleanup efforts are precarious amid the country's economic crisis and shifting blame between refugees and government inaction.

Alkaline hydrolysis is an end-of-life option that’s gaining popularity in Canada and the U.S. It’s marketed as a greener form of cremation — a way to still end up with ashes, but without sending harmful emissions into the air. But getting the technology approved by lawmakers has proven difficult.

When Pervis Payne was sentenced to death more than three decades ago, it was permissible to execute someone with an intellectual disability. A Supreme Court decision changed that in 2002, but Payne's disability was acknowledged only last year. Why did it take so long to remove him from The Row?

Urbanization in Lagos, Nigeria, is moving at a rapid clip — burying mangrove forests and wetlands under mounds of sand to make way for wealthy subdivisions. Without strong regulations around how that sand is harvested, the social, economic, and environmental consequences are vast.

Scientists and counterterrorism experts believe understanding the underlying motivations of radical extremists will help them deradicalize people. Now, one group has studied the brain activity of active extremists after asking them to contemplate the values they are willing to fight and die for.

In December of last year, Congress passed legislation that gives the Environmental Protection Agency authority to phase out most hydrofluorocarbons — potent greenhouse gases that keep refrigerators cool — over the next 15 years. But there's no perfect alternative to replace them.

Twenty years ago Portugal decriminalized all drugs as part of a bigger national strategy to fight addiction. Last month Oregon became the first U.S. state to do the same, in a policy modeled off Portugal’s approach — but many questions about how success may translate remain unanswered.

Amid a worldwide mental health crisis, the discovery of new pharmaceuticals to treat conditions like depression has stalled. But researchers and therapists are showing that when paired with therapy, psychedelic drugs like LSD and magic mushrooms are a new class of promising treatments.

In India, macaque monkeys are a menace — attacking people for food, breaking into offices, and in one state, damaging at least 54 million dollars worth of crops. A sterilization program aimed to curb the population, but some experts and locals question if it’s working or even the right approach.

A recent U.S. Supreme Court decision on the dusky gopher frog now has conservationists and developers squaring off over the legal definition of the term ‘habitat.’ The accepted meaning will guide American lawmakers in designating protected areas for endangered species across the country.

In South Africa, trauma researchers are studying — and working to ease — the psychological toll of Covid-19, while trying to endure the pandemic themselves. They warn the widespread and long-lasting impacts of this collective trauma could span generations and cross national borders.

As smoky summers resulting from wildfires have become the new normal across much of the West Coast, communities have tried to put better systems in place protect their most vulnerable residents. But this year, they didn’t plan on dealing with a smoke wave in the middle of a pandemic. How are they coping?

This month: Acoustic ecologists are racing to record Earth’s shifting soundscapes before they disappear. Some researchers are using their recordings to answer questions about how the environment and its inhabitants are changing, while others are sounding the alarm on pressing conservation issues.

This month: Communicating about animal research with the public can open early career scientists up to social stigma and even campaigns that threaten careers. But working with animals can be an emotionally taxing job — and the silence could isolate scientists further and strengthen public misconceptions.

This month: Ground-up waste leftover from asbestos mining still lines the landscape of Quebec. Now, a number of companies are eager to transform that waste into profitable product — but health officials worry this new industry might reawaken an old problem the province finally seemed to be moving away from.

This month: Tailoring medicine to each individual patient could make health care more affordable and effective. But that reality won’t come to fruition unless researchers, industry, the government, and the public reach a consensus on issues like patient privacy, data bias, and sharing of medical records.

This month: The impulse to “fix” intersex infants with invasive surgeries is facing increased and, some would argue, long overdue scrutiny. As doctors, parents, and intersex people face decisions that may affect their long-term health, researchers grapple with defining and measuring outcomes.

This month: Proponents of a new farming technique called regenerative agriculture argue that it can restore the earth, combat climate change, and alleviate the economic needs of farmers in debt. Now, farmers and researchers alike are putting claims about what this method can actually accomplish to the test.
