Dense branching and spines are common features of plant species in ecosystems with high mammalian herbivory pressure. The combination of dense branching and spines is likely to produce the most effective herbivore defenses, as dense branching directly tra

Cells rely on complex molecular machines composed of protein assemblies to perform essential functions such as energy production, gene expression, and protein synthesis. To better understand how these machines work, scientists capture snapshots of them by

Over the past 30 years, Australia's Tasmanian devil population has been afflicted with an infectious cancer that has pushed the species to near extinction. The marsupials are highly susceptible to devil facial tumor disease, which is almost always fatal

James Cook University researchers have discovered Indigenous fire management in northern Australia was being practiced at least 11,000 years ago—and it has implications for fire management practices today.

Numerous anti-cancer drugs function by targeting the DNA within cancerous cells, halting their proliferation. Yet, cancer cells occasionally develop mechanisms to repair the damage inflicted by these drugs, diminishing their effectiveness.

The warming of the Earth's oceans due to climate change is affecting where the world's fishes live, eat, and spawn—and often in ways that can negatively impact their populations. That's according to a new paper published in the journal Nature

Researchers at the Texas A&M University School of Veterinary Medicine and Biomedical Sciences (VMBS) have developed a new virtual tool that will allow scientists to study the function of genes more efficiently and hopefully reduce the number of an

A new Imperial College London study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.

Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years, they have attained notoriety for a completely different reason: it has been suggested that instead of one giraffe species, there might be no fe

Statistics made available in January 2024 show that while deforestation in the Amazon fell by half in 2023, it increased by 43% in the Cerrado, the Brazilian savanna. A research group at the State University of Campinas's Institute of Biology (IB-UNICAMP

The trillions of bacteria that call your body home—collectively known as the microbiome—appear to be unique to you, like a fingerprint. That's one conclusion of a detailed study of the gut, mouth, nose and skin microbiomes of 86 people. Over the course o

An international team of paleontologists from The Netherlands, the UK, Argentina, Germany and Belgium applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogene
