Researchers have discovered genes linked to obesity in both Labradors and humans. They say the effects can be over-ridden with a strict diet and exercise regime.

A sweeping study for the first time tallies butterfly data from more than 76,000 surveys across the continental United States. The results: Butterflies -- all of them -- are disappearing.

Researchers have discovered the world's oldest known meteorite impact crater, which could significantly redefine our understanding of the origins of life and how our planet was shaped. The team found evidence of a major meteorite impact 3.5 billion years ago.

Within the next decade, space agencies plan to bring samples of rock from Mars to Earth for study. Of concern is the possibility these samples contain life, which could have unforeseen consequences. Therefore, researchers in this field strive to create methods…

A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers.

Using two species of flies from different climates -- one from the cool, high-altitude forests of Northern California, the other hailing from the hot, dry deserts of the Southwest -- scientists discovered remarkable differences in the way each processes…

Cement manufacturing and repair could be significantly improved by using biocement-producing bacteria, but growing the microbes at construction sites remains a challenge. Now, researchers report a freeze-drying approach that preserves the bacteria, potentially…

Antimalarial drug resistance is a pressing issue in combating the spread of malaria worldwide. In a new study, researchers discovered a key process where malarial parasites take up a human blood cell enzyme, which could provide a new approach for antimalarial…

The study shows caribou herds changed their migratory duration, distance or elevation over 35 years of radio tag tracking.

Some bacteria deploy tiny spearguns to retaliate against rival attacks. Researchers mimicked attacks by poking bacteria with an ultra-sharp tip. Using this approach, they have uncovered that bacteria assemble their nanoweapons in response to cell envelope…

A team has found two antibodies that can work together to neutralize the virus that causes COVID-19 in all its current known variations in a laboratory environment. More research is needed, but the approach shows promise in developing treatments to keep pace…

Whether it's rivers cutting through earth, lava melting through rock, or water slicing through ice, channels all twist and bend in a seemingly similar back-and-forth manner. But a new study has discovered that channels carved by rivers actually have curves…

The beloved Australian lyrebird best known for its stunning tail and powers of mimicry may have a cunning hidden talent.

Engineers have developed a method to utilize aluminum to improve performance of water electrolysis catalyst.

A newly developed pentanuclear iron complex can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex, researchers have obtained a polymer-based catalyst, poly-Fe5-PCz, and achieved water…

A new study confirms the Antarctic ozone layer is healing as a direct result of global efforts to reduce ozone-depleting substances.

Amphibians are increasingly vulnerable to global warming, according to new research.

The oldest collection of mass-produced prehistoric bone tools reveal that human ancestors were likely capable of more advanced abstract reasoning one million years earlier than thought, finds a new study.

Bigger, tastier tomatoes and eggplants could soon grace our dinner plates thanks to scientists who have discovered genes that control how large the fruits will grow.

Researchers have uncovered a critical link between rising temperatures and declines in a species' population, shedding new light on how global warming threatens natural ecosystems. The study revealed that rising temperatures exacerbate competition within…

Plants and microbes are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Now, researchers report iron oxides can drive the same conversion at comparable rates as enzymes. The study adds yet another missing piece…

Soilless growing systems inside greenhouses, known as controlled environment agriculture, promise to advance the year-round production of high-quality specialty crops, according to an interdisciplinary research team. But to be competitive and sustainable, this…

Scientists examined the bitterness intensity of five medicines and two bitter modifiers in 338 adults of European descent and recent US and Canadian immigrants from Asia, South Asia, and Africa. Bitterness ratings differed by ancestry for two of the five drugs…

Researchers have created a system to help beekeepers monitor and analyze the health of their beehives and take corrective actions to prevent colony collapse -- when a majority of the worker bees abandon the colony and its queen. Beehives use thermoregulation…

Researchers achieved a breakthrough in understanding the vulnerability of microbes to the alcohols they produce during fermentation of plant biomass.

A vivid new image is taking shape in the world of cell biology: Imagine bacteria adhering to the surface of a cell, perhaps at the site of an injury or wound. In response, a white blood cell arrives at the scene. This cell encircles the pathogen with its…

A research team is studying whether artificial intelligence (AI) could play a supportive role in the evaluation of respiratory disease in pigs.

The molecular structure of the motor component that powers the gliding apparatus of Mycoplasma mobile, one of the few mycoplasma bacteria that can move, has been revealed using cryo-electron microscopy.

Researchers have discovered that what was previously thought to be a unique seaweed species of bladderwrack for the Baltic Sea is in fact a giant clone of common bladderwrack, perhaps the world's largest clone overall. The discovery has implications for…

A new study offers a more precise picture of exactly where and how warming will affect our ability to grow food.
