In a two-year greenhouse experiment, plants pollinated by bumblebees without herbivory evolved more attractive flowers, while those with herbivory had higher concentrations of defensive toxic metabolites. Plants developed a tendency to spontaneously self-pollinate when damaged by caterpillars.
A global study found that melting glaciers worldwide have caused a significant increase in global sea levels over the past 30 years, with 19,000 glaciers losing an average of 27 millimeters of ice since 1961. The largest contributors were glaciers in Alaska and Patagonia, resulting in a 335 billion-ton annual loss of glacier ice.
A recent study found that climate change can have long-lasting negative impacts on dolphin populations, with a 12% decrease in survival rate following a heatwave in Shark Bay, Western Australia. The researchers also observed fewer births among female dolphins, which persisted for at least six years.

They found that body size plays a significant role in determining the animals' resting posture, with larger animals more likely to lie on their sides and smaller ones on their chests.
Researchers found that a small yeast species called Malassezia strengthens the body's defenses against pathogens, but its balance with the immune system is key to preventing atopic dermatitis. A new potential treatment targets this balance by neutralizing interleukin-17 cytokine production.
A study by an international team led by researchers at the University of Zurich found that diet-induced changes in the human bite resulted in new speech sounds, contradicting the theory of a fixed range of human sounds. This shift allowed for the rise of labiodentals, such as the sound 'f', in modern languages.
A study found that negative emotions suppress trust by disrupting brain activity and connectivity in key social cognition regions. Negative affect also impairs the strength of connections between these regions, predicting lower levels of trust.
Researchers from the University of Zurich have virtually reconstructed a Neanderthal skeleton and found that they walked upright with a curved lumbar region and neck, similar to modern humans. This challenges previous reconstructions that depicted Neanderthals as having poor posture.
Researchers have discovered that bat influenza viruses can infect humans and livestock by using the MHC-II molecule to enter host cells. This finding suggests that these viruses have the potential to cause zoonotic transmission, leading to serious illnesses and deaths.

New findings suggest that the immune system's response to a protein called GDP-L-fucose synthase, found in both human cells and bacteria, may play a key role in multiple sclerosis. The protein is believed to activate T cells in the intestine, leading to an inflammatory cascade that damages the protective coating around nerve cells.
A study of 178 countries found a strong negative correlation between family size and cancer incidence, with larger families having a protective effect against various types of cancer. The protective effects are stronger for males than females, with non-reproduction-related cancers also being involved.
A large-scale forest biodiversity experiment in China found that species-rich forests stored an average of 32 tons of carbon per hectare, while monocultures averaged only 12 tons. The study suggests that a mix of tree species is necessary for optimal carbon sequestration and climate protection.
