An algorithm suggests a sidewalk-space redesign to make cities safer for pedestrians

A recent study in Communications Physics is among the first to systematically analyze whole city networks of spider-webbing roads and sidewalks. Examining 10 global cities, including Boston, Paris, and New York, researchers created an algorithm that could help planners choose … Continue reading

Digital reconstruction gets to the root of 400-million-year-old plant

Researchers have managed to reconstruct the detailed 3-D structure of a fossilized plant more than 400 million years old. The ancient leafy organism, a relative of today’s clubmosses, grew in the Early Devonian era—a crucial time for the development of … Continue reading

Robot swarms communicate best when messages spread neighbor to neighbor

In the not-so-distant future, swarms of robots could help contain environmental disasters such as wildfires, by locating and dousing the most dangerous patches, even as flames move and spread. But how would these individual robots coordinate effectively to pull off … Continue reading

Forests fight drought, even from far away

Forests are said to be the lungs of the Earth—they also provide a moist breath that travels tens to thousands of miles. Dense stands of trees release foggy clouds of condensation. The water molecules from those clouds ride wind currents … Continue reading

Drought causes lasting changes to the rice root microbiome

Beneficial microbes living in and around a crop’s roots could be powerful allies in the fight to keep plants alive through droughts, especially as climate change worsens. But before scientists can harness these microbial partners to make crops more resilient, … Continue reading

Well-connected members of tight-knit groups spread controversial ideas much more readily than “influencers”

The people who spread new and controversial ideas—changes in diet, exercise routine, political leaning, or even attitudes about vaccination—may not be the Kim Kardashians and Paris Hiltons. According to a recent study in Nature Communications, those with the most actual … Continue reading

Prion-like protein acts as water sensor in seeds

The sprouting of a seed is clearly a crucial stage in a plant’s life. Yet one part of the process has long been shrouded in mystery: How do seeds know when there’s enough water to germinate? Researchers recently reported the … Continue reading

Study suggests mask-wearing reduces the odds of self-infection with SARS-CoV-2

COVID-19 typically turns deadly when the virus infects the lungs. Hence, how exactly SARS-CoV-2 gets deep into the respiratory tract has been a pressing question since the pandemic started early last year. One pathway is well known: Most people catch … Continue reading

Degradable plastic polymer breaks down in sunlight and air

Plastic trash chokes shorelines and oceans, in part because plastic polymers do not easily decompose. But a new kind of environmentally degradable plastic could help change that: It breaks down in about a week in sunlight and air, according to … Continue reading

Emotional associations, more than knowledge, determine how much people care about the deep sea

With new technological advances in deep-sea mining, the ocean floor’s trove of valuable metals and rare earth elements is coming within reach of commercial mining operations. The impending reality of this practice, and its associated environmental risks, raises the question … Continue reading

New culturing techniques track crucial stage of embryo development

The second week of gestation is crucial for human development, as the growing embryo needs to implant in the mother’s womb to survive. Many early pregnancies fail at this point, but it has been difficult to determine exactly why. Lacking … Continue reading
