Scientists have shown that certain nanomaterials, such as carbon nanotubes, enter cells tip-first and almost always at a 90-degree angle. The orientation ends up fooling the cell; by taking in the rounded tip first, the cell mistakes the particle for a sphere, rather than a long cylinder. By the time the cell realizes the material is too long to be fully ingested, it's too late.

Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large "macroscopic" object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales.

Research by a team from two European universities and SLAC National Accelerator Laboratory shows that attractive forces between other parts of a molecule can make a stretched bond joining two carbon atoms much more stable than expected. This result should lead to improvements in how scientists design new molecules, materials and catalysts.
