Sometimes it takes time to uncover natures secrets. Take the case of callimicos, also called Goeldis monkeys, a reclusive and diminutive South American primate. Discovered a century ago by Swiss naturalist Emil August Goeldi, the animals were once considered to be a possible "missing link" between small and large New World monkeys.

But new findings from the first long-term studies of the monkeys in the wild seem to indicate that this is not the case, although the animals have a unique set of anatomical, reproductive and behavioral characteristics.
Leila Porter, a biological anthropologist at the University of Washington, has spent nearly four years observing callimicos (Callimico goeldii) in the Amazon basin of Northern Bolivia. Her pioneering fieldwork has collected the first detailed data of the ecology and behavior of the animals, an endangered species, in the wild. Among other things, her observations show callimicos eat fungi during the dry season, making them the only tropical primate species to subsist on this food source for part of the year. They also have a different reproductive strategy from other small New World monkeys. Callimicos (Latin for beautiful little monkeys) have the capacity to give birth to a single offspring twice annually while their closest primate relatives – marmosets, tarmarins and lion tarmarins – give birth to twins once a year.
Porters findings have just been published in the journal Evolutionary Anthropology in a paper she authored with Paul Garber, a biological anthropologist from the University of Illinois at Urbana-Champaign.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
