A chemosensory protein enriched in the legs of malaria-carrying mosquitoes gives them resistance to insecticides used to treat bed nets. This discovery points to the challenges of tackling malaria.
A combination of laboratory experiments and mathematical and statistical analysis provides an affirmative answer to a decades-old question — can a predator and its prey coexist indefinitely?
The brain fluctuates between different internal states, each of which drives particular behaviours. Brain-wide imaging reveals the internal states that help zebrafish larvae to choose between exploring and hunting.
A material that has electrically conducting surfaces has been found to show, when cooled, a type of magnetic ordering that reduces conduction at the surfaces. Such remarkable behaviour could have practical applications.
Current barriers and limitations to HIV treatments are reviewed, and suggestions for future steps to achieve an effective curative intervention are discussed.
The slipperiness of ice is poorly understood at a microscopic level. Experiments that probe how the surface of ice melts and flows in response to wear help to explain the exceptionally low friction that underpins winter sports.
Experiments show that quantum fluctuations can allow heat to be transported between two objects separated by a vacuum gap. This effect could be harnessed to exploit and control heat transfer in nanoscale devices.
Enhancing antitumour immune responses has revolutionized cancer treatment, yet some hurdles impede this approach. The discovery of a way to boost the lifespan and function of antitumour immune cells removes a key obstacle.
Immune cells called cytotoxic T cells can recognize and destroy cancer cells. The finding that stem-cell-like T cells exist in tumours, at niche sites that support these cells, could aid efforts to boost anticancer immune responses.
A double membrane protects certain bacteria from antibiotics, but compounds have now been generated that can overcome this obstacle, seemingly by targeting a crucial protein in the outer membrane.
In 1994, an unconventional form of superconductivity was detected in strontium ruthenate. The discovery has shed light on the mechanism of unconventional superconductivity at high temperatures.
Plaques are lipid-rich structures in the blood-vessel wall that can cause heart attacks or strokes if they rupture. It now seems that blood-cell fragments called platelets alter the function of immune cells in ways that accelerate plaque formation.
Scattering between electrons in the material graphene can cause these particles to flow like a viscous liquid. Such flow, which has previously been detected using measurements of electrical resistance, has now been visualized.
NASA’s Parker Solar Probe is currently making a series of close encounters with the Sun. Initial observations from the spacecraft have improved our understanding of both the Sun and its environment.
Conventional alloys have undesirably coarse-grained microstructures when used in 3D printing. A designer alloy overcomes this problem, potentially opening the way to the widespread adoption of 3D metal printing.
Knowing how dietary fibre nourishes gut microorganisms might suggest ways to boost health-promoting bacteria. A method developed to pinpoint bacteria that consume particular types of dietary fibre could advance such efforts.
