Gold adsorbed on metal oxides is an excellent catalyst for the room-temperature oxidation of CO to CO2. However, there has been continuing disagreement between different – [Read More]
26 Sep
During an infection, T cells divide extensively and secrete proteins that can severely damage tissues. But T cells know when to stop—they express proteins on their surface such as C – [Read More]

Patients paralyzed from a spinal cord injury may soon be able to move their legs more naturally. Current neuromodulation devices cause leg movement by electrically stimulating the spinal – [Read More]
26 Sep
Scientists have known that solar radiation ionizes the gases from Io's volcanoes to create a torus of plasma around Jupiter, but how that plasma moves is unclear. To investigate this, – [Read More]
26 Sep
The endothelium that lines blood vessels can undergo a change called the endothelial-to-mesenchymal transition (EndMT), which can cause vessel “scarring.” Such scarring limits the suc – [Read More]
26 Sep
Even though a basketball player is bigger than a gymnast, their neural tubes are organized in the same way. Studying chick and mouse embryos, Kicheva et al. show that rates – [Read More]
26 Sep
Meteorites found on Earth contain a wide range of complex constituent molecules, including amino acids. Astrochemists proposed the existence of these molecules in interstellar space – [Read More]
26 Sep
We know that life's favorite molecule, water, exists throughout the solar system. What we don't know is whether present water levels reflect the chemical conditions of our parent nebula – [Read More]
26 Sep
To determine the epigenetic mechanisms that direct blood cells to develop into the many components of our immune system, the BLUEPRINT consortium examined the regulation of DNA and – [Read More]
26 Sep
Nitrogen gas (N2) is abundant in Earth's atmosphere; however, it must be converted into a bioavailable form before it can be incorporated into biomolecules. The enzyme nitrogenase, – [Read More]
26 Sep
In the past several years, perovskite solar cells have emerged as a low-cost experimental alternative to more traditional silicon devices. Luo et al. now show that a pair of – [Read More]
26 Sep
Ozone's damaging role in the upper atmosphere is well known, but ozone is also quite active closer down to where we live. In particular, ozone's run-ins with airborne unsaturated hydrocarbons, – [Read More]
26 Sep
Levallois technology is the name for the stone knapping technique used to create tools thousands of years ago. The technique appeared in the archeological record across Eurasia 200 – [Read More]
26 Sep
Factors controlling plant species diversity have been teased apart in an ancient dune ecosystem in western Australia. Laliberté et al. surveyed plants in the ancient dune, – [Read More]
26 Sep
Animal behavior is learned and reinforced by rewards. On a molecular level, the reward comes in the form of the neurotransmitter, dopamine, which modulates synapses. The exact timing – [Read More]

When we think of nature conservation, some of us may imagine wilderness protected in a natural park. Others may think of species closer to home, such as birds and butterflies helped – [Read More]
