A research team at the Medical University of Vienna has discovered a new approach to treating a particularly frequent and difficult-to-treat form of lung cancer. The study shows that a combination of two well-studied classes of drugs—ERBB inhibitors and Aurora kinase inhibitors—is significantly more effective against KRAS-mutated lung adenocarcinomas than existing therapies. The research, currently published in the journal npj Precision Oncology, opens up a new and promising path for patients for whom there are currently only limited treatment options.

Environmentally friendly buildings are highly attractive for sustainable development and efficient energy consumption. Recently, scientists have made significant strides toward the development of energy-efficient smart windows—with features such as optical modulation, high transparency, low thermal conductivity, and ultraviolet (UV) blocking and heat shielding capabilities—to replace traditional glass windows. Smart windows are a lucrative technology to protect household items as well as human health from the adverse effects of UV radiation.

Researchers at the University of Konstanz have developed a gentle, contact-free method to collect liquids and remove them from microscopic surface structures. The method uses vapor condensation to generate surface currents that transport droplets off surfaces.

Underground environments like soil and aquifers teem with microbial life. These tiny microbes play a big role in cycling nutrients and breaking down or transforming pollutants. However, scientists still struggle to reliably model how microbes grow and decay.

Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it help mothers or young survive?

Evolutionarily speaking, the ultimate goal of a lifeform is to reproduce and stave off extinction. Many plants and animals have evolved unique tricks to do so. One of these tricks is mimicry, which might be used to trick other species into believing it is dangerous in order to avoid becoming a meal, or to increase the likelihood of reproduction.

As generative artificial intelligence tools rapidly enter classrooms, workplaces, and creative industries, questions about what these systems mean for human creativity have become increasingly urgent.

Today, pediatric experts from Children's Hospital Colorado (Children's Colorado) announced published research in the Journal of the American Academy of Child and Adolescent Psychiatry that identifies five classifications of youth who have died by suicide. Using 10 years of national suicide data, Joel Stoddard, MD, MAS, child and adolescent psychiatrist at Children's Colorado, and his team found that nearly half of youth who died by suicide did not have clinical contact or a known risk of suicide. These findings are critical for recommending new and increased suicide interventions for youth.

Heart disease remains the leading cause of death worldwide, yet progress in understanding and treating cardiac disorders is limited by the shortcomings of existing experimental models. Traditional animal models often fail to capture human-specific cardiac biology, while conventional two-dimensional cell cultures lack the functional and structural complexity of heart tissue.
