When Temperatures Get Cold, Newly-Discovered Process Helps Fruit Flies Cope

Cold-blooded animals cannot regulate their body temperature, so their cells are stressed when facing temperature extremes. Worse still, even at slightly colder temperatures, some biological processes in the cell are slowed down more than others, which should throw the cells’ delicate chemical balance out of whack. Yet, those cells manage to keep their biological processes coordinated. Now researchers have found out how they do that.

Speedy Computation Enables Scientists to Reconstruct an Animal’s Development Cell by Cell

Press.jpg.jpeg

Researchers at the Howard Hughes Medical Institute’s Janelia Research Campus have developed a new computational method that can rapidly track the three-dimensional movements of cells in such data-rich images. Using the method, the Janelia scientists can essentially automate much of the time-consuming process of reconstructing an animal's developmental building plan cell by cell.

Faithful Cell Division Requires Tightly Controlled Protein Placement at the Centromeres

The protein CENP-A, which is integrated into human DNA at the centromere on each chromosome, has a vital role in cell division. Work from Whitehead Institute Member Iain Cheeseman’s lab describes how the vital and tightly controlled replenishment of CENP-A progresses.

A Region and Pathway Found Crucial for Facial Development in Vertebrate Embryos

A signaling pathway once thought to have little if any role during embryogenesis is a key player in the formation of the front-most portion of developing vertebrate embryos. Moreover, signals emanating from this region—referred to as the “extreme anterior domain” (EAD)—orchestrate the complex choreography that gives rise to proper facial structure.

Molecular ‘Eat Now’ Signal Makes Cells Devour Dying Neighbors

HeLaengulfingapoptoticcells_web.jpg

A team of researchers has devised a Pac-Man-style power pellet that gets normally mild-mannered cells to gobble up their undesirable neighbors. The development may point the way to therapies that enlist patients’ own cells to better fend off infection and even cancer, the researchers say.
