MORPHOGENESIS and malignant invasion seem to be dependent on cellular migration and changes in cellular adhesiveness1-3. Plant lectins such as concanavalin A (con A) have been extensively used to study the nature and distribution of lectin receptor si . . .

Modern humans arrived in Europe ~45,000 years ago, but little is known about their genetic composition before the start of farming ~8,500 years ago. Here we analyse genome-wide data from 51 Eurasians from ~45,000-7,000 years ago. Over this time, the p . . .

The adhesive properties of cell surfaces which seem to determine many morphogenetic processes1 and which may be important in malignancy2 must reflect the biochemical characteristics of the cell surfaces. There have been attempts to isolate the macromo . . .

"Debris disks" around young stars (analogues of the Kuiper Belt in our Solar System) show a variety of non-trivial structures attributed to planetary perturbations and used to constrain the properties of those planets[1-3]. However, these analyses hav . . .

Paleoenvironmental records from a southern California coastal saltmarsh reveal evidence for repeated late Holocene coseismic subsidence events. Field analysis of sediment gouge cores established discrete lithostratigraphic units extend across the wetl . . .

Methane cold seep systems typically exhibit extensive buildups of authigenic carbonate minerals, resulting from local increases in alkalinity driven by methane oxidation. Here, we demonstrate that modern seep authigenic carbonates exhibit anomalously . . .
