Another beautiful helix for biology, this time reminiscent of a parking garage

Leave a comment

The endoplasmic reticulum (ER) is the protein-making factory within cells consisting of tightly stacked sheets of membrane studded with the molecules that make proteins. In a study published July 18th by Cell Press in the journal Cell, researchers have refined a new microscopy imaging method to visualize exactly how the ER sheets are stacked, revealing that the 3D structure of the sheets resembles a parking garage with helical ramps connecting the different levels. This structure allows for the dense packing of ER sheets, maximizing the amount of space available for protein synthesis within the small confines of a cell. …read more

Chimpanzees and orangutans remember distant past events (w/ Video)

Leave a comment

We humans can remember events in our lives that happened years ago, with those memories often surfacing unexpectedly in response to sensory triggers: perhaps a unique flavor or scent. Now, researchers reporting in Current Biology, a Cell Press publication, on July 18 have evidence to suggest that chimpanzees and orangutans have similar capacities. In laboratory tests, both primate species were clearly able to recollect a tool-finding event that they had experienced just four times three years earlier and a singular event from two weeks before, the researchers show. …read more

European fish stocks poised for recovery

Leave a comment

The results of a major international effort to assess the status of dozens of European fish stocks find that many of those stocks in the northeast Atlantic are being fished sustainably today and that, given time, those populations should continue to recover. The findings, reported in the Cell Press journal Current Biology on July 18, come as surprisingly good news amid widespread criticism that the European Union’s Common Fisheries Policy is failing, the researchers say. …read more

Learned helplessness in flies and the roots of depression

Leave a comment

When faced with impossible circumstances beyond their control, animals, including humans, often hunker down as they develop sleep or eating disorders, ulcers, and other physical manifestations of depression. Now, researchers reporting in the Cell Press journal Current Biology on April 18 show that the same kind of thing happens to flies.

Rare primate's vocal lip-smacks share features of human speech

Leave a comment

The vocal lip-smacks that geladas use in friendly encounters have surprising similarities to human speech, according to a study reported in the Cell Press journal Current Biology on April 8th. The geladas, which live only in the remote mountains of Ethiopia, are the only nonhuman primate known to communicate with such a speech-like, undulating rhythm. Calls of other monkeys and apes are typically one or two syllables and lack those rapid fluctuations in pitch and volume. …read more

Sustainable fishing practices produce local rewards

Leave a comment

Communities that act locally to limit their fish catches will reap the rewards of their action, as will their neighbors. That’s the conclusion of a study reported on March 28 in the Cell Press journal Current Biology of the highly sought-after fish known as squaretail coral grouper living in five community-owned reef systems in Papua New Guinea. …read more

Where, oh where, has the road kill gone?

Leave a comment

Millions of birds die in the US each year as they collide with moving vehicles, but things have been looking up, at least in the case of cliff swallows. Today’s swallows are hit less often, thanks to shorter wingspans that may help them take off more quickly and pivot away from passing cars. The findings, reported in the Cell Press journal Current Biology on March 18, show that urban environments can be evolutionary hotspots. …read more

Sniff, sniff. What did you say?

Leave a comment

When animals like dogs or rats sniff one another, there might be more going on than you’d think. Research reported in Current Biology, a Cell Press publication, on March 7th finds in rats that those sniffing behaviors communicate information about an individual’s social status. In those encounters, more dominant rats act as primary sniffers, while subordinate sniffees actually slow their breath. …read more

Fighting GM crop vandalism with a government-protected research site

Leave a comment

Genetically modified (GM) crops have been a source of great controversy—particularly in Europe—but acts of vandalism and associated security costs have made scientific evidence about the health and ecological impacts of those crops hard to come by. A Swiss government-protected field site dedicated for use in GM crop studies could serve as an example to other European countries interested in pursuing crop biotechnology, according to an article published in Trends in Biotechnology, a Cell Press publication, on February 28. …read more
