The future of ocean health

Human and environmental health are inextricably linked. Yet ocean ecosystem health is declining because of anthropogenic pollution, overexploitation, and the effects of global climate change. These problems affect billions of people dependent on oceans for their lives, livelihoods, and cultural practices. The importance of ocean health is recognized by scientists, managers, policy-makers, nongovernmental organizations, and stakeholders including fishers, recreationalists, and cultural practitioners. So why are the oceans still degrading?

Science Magazine – August 25, 2023: This image depicts whole chromosomes, some with structural abnormalities that might be found in cancer. The idea that cancer cells have aneuploidy—abnormal numbers of chromosomes and chromosome portions—has been known for decades.

If AI becomes conscious, how will we know?

Scientists and philosophers are proposing a checklist based on theories of human consciousness

0s and 1s making up the outline of a head

In 2021, Google engineer Blake Lemoine made headlines—and got himself fired—when he claimed that LaMDA, the chatbot he’d been testing, was sentient. Artificial intelligence (AI) systems, especially so-called large language models such as LaMDA and ChatGPT, can certainly seem conscious. But they’re trained on vast amounts of text to imitate human responses. So how can we really know?

‘Still in shock.’ Amid wildfire tragedy, Maui scientists assess their research losses

Blazes and high winds blew projects apart and left a tight-knit research community shaken. What will it take to prevent future island fires?

The hall of historic Waiola Church in Lahaina and nearby Lahaina Hongwanji Mission engulfed in flames in Lahaina, Hawaii.

In the wake of a series of powerful wildfires that ripped through Maui’s dry forests and the historic city of Lahaina this week killing more than 50 people, researchers on the island remain concerned about the personal fallout for fellow scientists and their families. Some are reeling from disruption to their projects: Studies of whales may be disrupted, for example, and a rare plant facility sustained damage. “We’re still wrapping our heads around what this really means, because right now, most of us are still in shock,” says marine mammal ecologist Marc Lammers. “And, of course, we’re thinking about our colleagues.”

Science Magazine – August 4, 2023 issue: DNA was sequenced from 27 African Americans buried at Catoctin Furnace, Maryland, where enslaved people labored between 1774 and 1850. The tree trunk forms a double helix comprising 27 segments representing each sequenced individual.

Tropical trees deter similar neighbors

Tropical forests host an unusually high diversity of tree species. Strong interactions between individuals are hypothesized to create these patterns. A tree is more likely to survive when surrounded by different tree species with different resource needs, diseases, and herbivores. Kalyuzhny et al. found patterns consistent with this mechanism in a long-term forest plot in Panama. Adult trees in this site are more distant from members of their own species than from other species and more distant than would be expected by chance or by the limits of seed dispersal. This study shows that distances between conspecifics are maintained in adult trees, helping to explain the high diversity of tropical forests.

Science Magazine – July 28, 2023 issue: This artwork depicts social media users that are engaged (and often enraged) from the “left” (liberals, blue) and the “right” (conservatives, red) perched on Meta’s logo. Social media algorithms personalize users’ online experiences, recommending engaging content that will interest them and possibly spark outrage.

Social media and elections

The advent of social media forever changed how we consume news. At least half of Americans rely on it for news, and Facebook (owned by parent company Meta) is the most popular. Meta’s Facebook and Instagram platforms are funded through advertisements and generate more revenue when users spend more time on their platforms. To make platforms alluring and increase screen time, tech companies operate on business models that incentivize algorithms that are designed to elevate eye-catching content to the top of users’ feeds—content that captures attention and may go “viral” by stimulating “engagement” through comments, likes, and resharing.

Science Magazine – July 21, 2023 issue: The cover depicts an x-ray of a human skeleton walking. Researchers extracted 23 skeletal proportions from 30,000 individuals using deep learning. Coupled with genetic and biobank data, more than 100 genetic variants associated with these proportions were identified. These analyses shed light on the evolution of the skeletal form, which facilitates bipedalism, and reveal connections to musculoskeletal disorders.

Science Magazine – July 14, 2023 issue: There have been huge strides in the development and application of artificial intelligence (AI) to science and society. But will AI eclipse humans, or will we find a way to safely and fairly collaborate, allowing us to reach further?

A machine-intelligent world

Huge strides have been made in the development of machine-learning algorithms to generate what is commonly called artifi cial intelligence (AI). Looking to the forefront of how AI is being used in science and society reveals many benefi ts, as well as grand challenges, that must be addressed.

Leveraging artificial intelligence in the fight against infectious diseases

Despite advances in molecular biology, genetics, computation, and medicinal chemistry, infectious disease remains an ominous threat to public health. Addressing the challenges posed by pathogen outbreaks, pandemics, and antimicrobial resistance will require concerted interdisciplinary efforts.
