The Drosophila Gateway™ Vector collection is a set of 68 Gateway-based vectors designed to express epitope-tagged proteins in Drosophila culture cells or flies. At its core is Invitrogen's Gateway™ ...

Carnegie's newest scientific division, Biosphere Sciences & Engineering, is devoted to disrupting the traditional, siloed perspective on research in the life sciences and pursuing an integrated ...

Hydropower and irrigation are essential for achieving human development objectives and for climate mitigation and adaptation. These sectors depend on the same grey infrastructure, such as dammed ...

Sugars serve as the principal energy source, basic building material and important signal molecules in both animals and plants. Their distribution throughout the organism is controlled by sugar ...

Purple sulfur bacteria (PSB) are important photoautotrophs inhabiting chemoclines in euxinic and meromictic lakes. These organisms are the only producers of the carotenoid, okenone, a compound that ...

The Hercules ultrafaint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to difficulties in ...

10.1111/j.1365-2966.2012.20586.x The presence of substructure in galaxy groups and clusters is believed to be a sign of recent galaxy accretion and can be used to probe not only the assembly history ...

Marine oxygen-deficient zones represent a natural source of nitrous oxide (N2O), a potent greenhouse gas and ozone-depleting agent. To investigate controls on N2O production, the responses of ammonia ...

Washington, DC— Pairing cutting-edge chemistry with artificial intelligence, a multidisciplinary team of scientists found fresh chemical evidence of Earth’s earliest life—concealed in 3.3-billion-year ...

Stella Ocker, a postdoctoral fellow at the Carnegie Observatories, studies the interstellar medium—the gas and dust between stars—and the diffuse ionized material that shapes galaxies like our own.

From teeming biodiversity hotspots to inhospitable environments where resilient microorganisms thrive, life has reshaped our planet. What can it teach our researchers about searching for signs of life ...

Our experts reveal how our planet formed, evolved, differentiated into layers and developed the interconnected system of dynamic processes that made it habitable and enabled life to arise and thrive.
