Baikal, Biwa and Bosuntwi. Maracaibo, Malawi and Matano. Tule, Tahoe and Titicaca.Ancient lakes, they're called: waterbodies more than 130,000 years old. Over their long histories, they've seen countless changes—warming and cooling cycles, wet and dry periods, altered biology and chemistry.
Brassica rapa plants pollinated by bumblebees evolve more attractive flowers. But this evolution is compromised if caterpillars attack the plant at the same time. As bees pollinate them less effectively, the plants increasingly self-pollinate. In a greenhouse evolution experiment, scientists at ...
A large portion of a plant is hidden below the ground. This buried root system is essential for the plant: it provides stability, water, and food. In contrast to mammals, where the body plan is final at birth, the formation of new root branches ensures that the root system keeps growing througho ...
In coral reef ecosystems, amid stony corals, fronds of algae and schools of fish, microorganisms are essential for recycling nutrients—transforming bits of organic matter into forms of nitrogen and phosphorus, for example, that are useful to photosynthetic organisms.
An EPFL doctoral student has come up with methods to map out forests more effectively using aerial remote sensing, in support of on-the-ground forest inventories.
Micro-encapsulated CO2 sorbents (MECS)—tiny, reusable capsules full of a sodium carbonate solution that can absorb carbon dioxide from the air—are a promising technology for capturing carbon from the atmosphere.
At least one running argument among cat lovers is now over: Whiskers, Lucy and Tigger are definitely better off staying indoors, scientists reported Wednesday.
On March 17, 2002, the German-U.S. satellite duo GRACE (Gravity Recovery and Climate Experiment) was launched to map the global gravitational field with unprecedented precision. The mission lasted 15 years, more than three times as long as expected. When the two satellites burned up in the Earth ...

Understanding how biodiversity is shaped by multiple forces is crucial to protect rare species and unique ecosystems.
A new study led by researchers at the University of Miami's (UM) Rosenstiel School of Marine and Atmospheric Science found that smoke from fires in Africa may be the most important source of a key nutrient -- phosphorus -- that acts as a fertilizer in the Amazon rainforest, Tropical Atlantic and ...
Recent primate research has had a heavy focus on a few charismatic species and nationally protected parks and forests, leaving some lesser known primates and their habitats at risk, according researchers at The University of Texas at Austin and Santa Clara University.
Scientists believe that the Earth is currently going through its sixth mass extinction event. However, there may have been another such incident in our planet's past that researchers had overlooked until now, according to a study published in the journal Historical Biology.
A team of researchers from Kyoto University, Primate Cognition Research Group and Conservation through Public Health, has found that wild mountain gorillas living in Uganda play very much like humans when having fun in the water. In their paper published in the journal Primates, the group descri ...
Honey bees are under extreme pressure. The number of honey bee colonies in the US has been declining at an average rate of almost 40% since 2010. The biggest contributor to this decline is viruses spread by a parasite, Varroa Destructor. But this isn't a natural situation. The parasite is spread ...
