Reaction previously believed detrimental for photosynthesis proves to be beneficial

Reaction previously believed detrimental for photosynthesis proves to be beneficial

Inspired by water transport in natural leaves (shown), researchers have created a synthetic, microfabricated «leaf» that can generate power from evaporative flow. Image credit: pdphoto.org Finnish researchers have demonstrated that photoinhibition of photosystem I, which reduces the effectiveness of photosynthesis, is actually a plant’s self-defense mechanism against more extensive harm. The research was funded by […]

This image shows the numbers of divisions for Chlamydomonas cells scale with mother cell size. Left to right are cells of increasing size with the first cell too small to divide and next four undergoing one, two, three or four divisions to produce 2, 4, 8 or 16 daughters.

A programming language for living cells

A programming language for living cells

MIT biological engineers have devised a programming language that can be used to give new functions to E. coli bacteria. Credit: Janet Iwasa MIT biological engineers have created a programming language that allows them to rapidly design complex, DNA-encoded circuits that give new functions to living cells. Using this language, anyone can write a program […]

New genus of treehopper named after Selena Quintanilla, the queen of Tejano music

  Selenacentrus wallacei, a newly discovered genus and species of treehopper found in Texas and Northern Mexico. They new genus is named after the singer Selena Quintanilla, who was known as the ‘Queen of Tejano Music.’ The new species is called wallacei in honor of Matthew S. Wallace, a biology professor from East Stroudsburg University. […]

Biologists report on the long-term effects of heat stress on cells

Biologists report on the long-term effects of heat stress on cells

A process of cell senescence is set in the early S-phase, when a topoisomerase-I collides a replication fork and a double-strand break appears. Credit: Sergey Razin (NAR paper) Heat shock (or stress) is a well-known factor of cell stress, though its delayed effects remain largely unknown. According to two articles by Russian scientists —a 2015 […]

Freezing plants to predict the fate of the Arctic

Freezing plants to predict the fate of the Arctic

Working in the depths of the polar night can have its challenges, but it can be breathtakingly beautiful, too. Credit: ystein Varpe, UNIS Global warming means much warmer winters in the Arctic, with more rain and icing. Researchers are working to understand what that will do to plants that have evolved to overwinter under a […]

Straw-colored fruit bats: Ecosystem service providers and record-breaking flyers

Colony of straw-colored fruit bats (Eidolon helvum) roosting in Accra, Ghana. Credit: MPI f. Ornithology/ J. Fahr African straw-coloured fruit bats fulfil important ecosystem functions by dispersing seeds and pollen during their flights. Researchers from the Max Planck Institute for Ornithology in Radolfzell together with colleagues from Ghana fitted African straw-coloured fruit bats (Eidolon helvum) […]

Stressed out: Scientist details cells’ response to lesions

Alessandro Vindigni, Ph.D., professor of biochemistry and molecular biology at Saint Louis University. Credit: Saint Louis University In a recent review paper published in Nature Structural & Molecular Biology, SLU scientist Alessandro Vindigni, Ph.D., describes the strategies cells use when their DNA faces replication stress, challenges that may derail a cell’s ability to reproduce. In […]

MSU part of team working to save endangered species in Nicaragua

The Baird’s tapir is one of several Central American animals that could be threatened by a canal project now under consideration in Nicaragua. An MSU researcher is a member of a team that has developed a conservation plan that might help save the habitat of this and other species. This photo was taken several years […]
