Ants are famous for their regimented and complex social behaviors. In the tropics, they are also famous for forming mutualisms with plants. Certain species of trees have conspicuous hollow swellings that house ants, often feeding the ants with specialized ant food. In return, the ants are pugnacious bodyguards, swarming out to aggressively defend the plant against enemies. Scientists have observed these mutualisms for centuries, but an enduring question is how these intriguing interactions evolved in the first place. That remains a mystery, but new research led by University ...

GWAS studies have provided foundational knowledge about the genetic basis of disease ...

When at the edges of their geographic ranges, fruit-eating birds favor foods that more closely match their beak size, researchers report, suggesting that foraging niches (the diversity of food resources a species uses) become more specialized toward the periphery of a species range. The findings may help explain geographic variation in species’ fitness and are important for accurately predicting species’ responses to continued environmental change, which is forcing many populations to live near or outside their historic range limits. Animals feed on a subset of available resources within their environment. Optical ...

In a Perspective, Daniel Drucker highlights the growing body of evidence that hints at the potential of glucagon-like peptide-1 (GLP-1)-based medications in treating conditions other than diabetes and obesity, including cardiovascular disease and neurodegenerative disorders. GLP-1 is a hormone released from the gut after eating that enhances glucose-dependent insulin secretion. Pharmacological GLP-1 receptor (GLP-1R) activation reduces glucagon secretion and slows gastric emptying, making it an effective treatment for type 2 diabetes. Later studies found that GLP-1 administration also inhibited food intake through ...

Artemisinin-based combination therapies (ACTs) have become the cornerstone of malaria treatment and control. However, the recent emergence and spread of artemisinin-resistance (ART-R) in malaria-causing Plasmodium falciparum parasites in eastern Africa has compromised the efficacy of these crucial treatments. In a Policy Forum, Mehul Dhorda and colleagues argue that urgent action is needed to prevent a surge in malaria-related sickness and death in the region. “Success in containing ART-R in the Greater Mekong Subregion in Asia, where ART-R was first reported in 2008, suggests that a multipronged approach is needed ...

The researchers found that rates of missed appointments increased by 0.72% for every 1°F decrease in daily maximum temperatures below 39°F and increased by 0.64% for every 1°F increase above 89°F. Patients 65 and older and those with ...

Oil drops from underwater oil spills can break into tinier droplets at the surface that remain suspended in the water, according to research from the University of Illinois Chicago. That means cleanups after disasters like the Deepwater Horizon spill may be removing less oil from the environment than was thought. Because oil is lighter than water, it rises through the ocean after spills, which are usually caused by leaking underwater pipelines or sometimes by natural processes. It was believed that when these ...

Scimitar syndrome, a rare congenital heart disease, involves an anomalous pulmonary venous return where the right pulmonary veins return to the inferior vena cava instead of the left atrium. It is mainly diagnosed in infants, with an estimated prevalence of 1–3 per 100,000 births. Delayed treatment can lead to pulmonary hypertension, right heart failure, respiratory failure, heart arrhythmia, and growth disorders. This syndrome is characterized by anomalous pulmonary venous drainage to the inferior vena cava, and the usual surgical repair involves re-implanting the right pulmonary veins (scimitar vein) to the left atrium or creating an intra-atrial tunnel to ...

In China, Property Rights Take Wrong Turn Protecting them fueled an economic boom; eroding them risks long-term damage AUSTIN, Texas — China’s economy, long an engine of world growth, has been sputtering lately. During the second quarter of 2024, it grew at an annual rate of 4.7% — down from an average 7% a year during the past decade. For the next two years, the International Monetary Fund forecasts more of the same. Analysts have blamed China’s slowdown on short-term factors, such as debt-ridden real estate and a delayed recovery from the COVID-19 ...

UNIVERSITY PARK, Pa. — As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated — if these “solar farms” are properly built. Solar panels are impervious to water, and vast arrays of them, it was feared, could increase the volume and velocity of stormwater runoff similar ...
