Study: Digitally Managed Larviciding

A new study has found that larval source management (LSM) – treating mosquito breeding habitats – can still be effective in malaria elimination operations, especially with the aid of new digital technologies. LSM has been replaced in Africa by long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS), but these methods are becoming less effective due to mosquitoes’ growing resistance to insecticides.

Anna Dumitriu: Exploring the Intersection of Art, Science, & Technology

British artist Anna Dumitriu’s name is synonymous with the world of BioArt. Not only is her work visually stunning, but it is also intellectually stimulating, as she tackles some of the most pressing issues of our time.

Dumitriu’s art explores our relationship to infectious diseases, artificial intelligence, and the impact of the pandemic from cultural and scientific perspectives. During her exploration of these topics, she has worked with the Liu Laboratory for Synthetic Evolution at the University of California in Irvine to investigate synthetic biology, and she has collaborated with BeyondSequ at the University of Birmingham to visually observe her CRISPR edit using super-resolution laser microscopy.

Dr. Agnes Kalibata: Sustainable Agriculture Advocate

When it comes to building a healthier and more sustainable future, few people have made as much of an impact as Dr. Agnes Kalibata. As a renowned agricultural scientist, policymaker, and advocate for nutrition and food security, Dr. Kalibata has spent decades working to improve the lives of people in her home country of Rwanda and around the world.

After growing up in an Ugandan refugee camp with her Rwandan parents, Dr. Kalibata earned a degree in agricultural sciences from Makerere University in Uganda and then went on to complete a PhD in entomology at the University of Massachusetts Amherst. However, it was her work in Rwanda’s Ministry of Agriculture that really put her on the map.

Earth Day & Public Health: Unavoidably Connected

Each year on April 22nd, people and nations around the world celebrate Earth Day to raise awareness and promote action toward environmental protection and sustainability. Activities typically include community clean-ups and educational campaigns designed to promote sustainability in daily life.

The origins of Earth Day date back to the 1960s and a decade of growing enviro-consciousness brought about by the publication of Rachel Carson’s Silent Spring and a series of environmental disasters that climaxed with a devastating oil spill off the coast of California in 1969. Gaylord Nelson, a U.S. Senator from Wisconsin, organized the first Earth Day in 1970, when an estimated 20 million Americans took part in organized activities ranging from tree plantings to beach cleanups and teach-ins on college campuses.

Since those humble beginnings, Earth Day has become a global event – but amidst the tree plantings and landscape revitalization lies a subtle and yet direct connection between Earth Day and Public Health. Just as we depend on the natural environment for our survival, civilization creates and shapes a social and economic environment that greatly influences the health and well-being of our species.

Rachel Sussman: Artistic Explorations of Natural Wonders

Rachel Sussman is a contemporary artist based in Brooklyn.

Sussman is a Guggenheim, NYFA, and MacDowell Colony Fellow, and two-time TED speaker. Her critically acclaimed, decade-long project “The Oldest Living Things in the World” combines art, science, and philosophy into a traveling exhibition and New York Times bestselling book.

Under the Canopy

Journey into the largest tract of tropical rainforest on our planet — the Amazon.

Narrated by indigenous guide, Kamanja Panashekung, and actor Lee Pace, this new virtual reality film by Conservation International and Jaunt VR takes you into the Amazon and urges the protection of world’s largest rainforest.

Infographic: Carbon & The Sea

By releasing greenhouse gases into the atmosphere, humans are changing the global climate in ways that are affecting the marine environment in terms of weather patterns, water temperature, sea level, ocean chemistry, currents, coastal erosion and the frequency of storms.

Forests & Earth’s Temperatures

Seeing the forest through the trees is an expression you may not think of when the topic of global warming comes up. However, 31% of the earth’s surface is covered by trees and each one is working overtime to sequester carbon to combat global warming. Carbon sequestration is a natural or artificial process by which carbon dioxide is removed from the atmosphere and held in solid or liquid form, and it is estimated that forests absorb approximately 7.6 billion metric tons of carbon annually.

Resistance in the Limelight

Doctor Shinji Kasai’s recent publication on the combined effects of three knockdown resistance (kdr) mutations in Aedes aegypti sparked media frenzy. He demonstrated the causal relationship between specific genes & pyrethroid sensitivity in mosquitoes.

The study improved understanding of insecticide resistance evolution & opened new strategies to control mosquito populations & reduce disease spread. Kasai’s latest paper on super-insecticide-resistant dengue mosquitoes caused a stir in the media, revealing high levels of pyrethroid resistance in field populations.

Urban Africa Faces Invasive Challenge

Malaria numbers are surging in the Horn of Africa, but not in rural settings.

Djibouti is a small country of around 900,000 inhabitants on the Horn of Africa that rests on the shores of Bab al-Mandab strait, just 20 miles from the coast of Yemen and southwest Asia. Ten years ago, the World Health Organization (WHO) proudly proclaimed that Djibouti was entering the “pre-elimination phase” in its longstanding battle against malaria. Pre-elimination status is reached when a country’s number of confirmed malaria cases approaches zero.
