Deciphering the beetle exoskeleton with nanomechanics
Northwestern Engineering's Horacio D. Espinosa and his group employed a creative way to identify the geometry and material properties of the fibers that comprise a beetle's exoskeleton. This work could ultimately uncover information that could guide the design and manufacturing of new and improved artificial materials through bio-mimicry. (2017-01-11)

Predation on invertebrates by woodland salamanders increases carbon capture
Woodland salamanders perform a vital ecological service in American forests by helping to mitigate the impacts of global warming. Woodland salamander predation on invertebrates indirectly affects the amount of leaf litter retained for soil-building where nutrients and carbon are captured at the litter-soil interface.

A new species of Darwin wasp from Mexico named in observance of the 2020 quarantine period
Scientists at the Autonomous University of Tamaulipas in Mexico recently discovered five new species of parasitoid wasps in Mexico, but the name of one of them is quite striking: covida. Described in a new paper, published in the peer-reviewed, open-access scientific journal ZooKeys, the new to science Darwin wasp was identified during the 2020 global quarantine period, imposed due to the COVID-19 pandemic.

Climate change blamed for dead trees in Africa
Trees are dying in Africa's Sahel, and human-caused climate change is to blame, according to a new study led by a scientist at UC Berkeley. Using climate change records, aerial and satellite images and field data, researchers found that one in five tree species disappeared in the past half-century. They attribute the tree deaths to the historic drops in rainfall and increased temperatures in the region. (2011-12-12)

New fossils push the origin of flowering plants back by 100 million years to the early Triassic
Drilling cores from Switzerland have revealed the oldest known fossils of direct ancestors of flowering plants. These beautifully preserved 240-million-year-old pollen grains are evidence that flowering plants evolved 100 million years earlier than previously thought, according to Rsearchers from the University of Zurich.

Jason Londt and Torsten Dikow publish updated information about all species within the genus, now counting a total of seven species, and also establish a new tribe. Their study is published in the open access journal African Invertebrates. (2016-12-06)

Tip Sheet: Citrus Limonoids Versus Cancer, Cholesterol And Insects
Limonoids are compounds in citrus fruits, generally found in the peels, that produce the familiar bitter taste. More importantly, limonoids have been shown to produce anticancer activities in animals and inhibit the spread of human breast cancer cells in culture. More than a dozen research papers related to these compounds are being presented during the national meeting of the American Chemical Society, the world's largest scientific society, in Anaheim, Calif., March 21 - 25.

Scientists develop new potato lines to wage war on wireworms
When wireworms feast on potatoes, the results aren't pretty: The spuds' surfaces are left punctured, pitted and unappealing. For the past few years, US Department of Agriculture scientists and their colleagues have sought a solution in the form of spuds with genetic resistance to the worms, with special attention focused on two wild potatoes from Chile and Bolivia: Solanum berthaultii and S. etuberosum. (2011-09-19)

First study to demonstrate long-term control of cane toads
Preventing cane toads from entering man-made dams to cool down in the hot, arid zones of Australia kills them in large numbers and is an effective way to stop their spread, University of New South Wales Australia-led research shows. The study, which involved erecting toad-proof fences around dams, is the first to demonstrate long-term control of the toxic amphibians. The research is published in the Journal of Applied Ecology. (2015-02-03)

Less is more for a hungry bat

Virginia Tech's smelly 'corpse plant' due to bloom Aug. 4
The smelly plant is rare because it puts forth one blossom every four to 10 years. This year, Virginia Tech's second such plant should bloom this week. Only about 20 Amorphophallus titanum, or titan arum, have bloomed in the United States since 1937. (2004-08-02)

Snack attack: Bears munch on ants and help plants grow

Cotton with special coating collects water from fogs in desert
Researchers at Eindhoven University of Technology together with researchers at the Hong Kong Polytechnic University, have developed a special treatment for cotton fabric that allows the cotton to absorb exceptional amounts of water from misty air: 340 percent of its own weight. What makes this 'coated cotton' so interesting is that the cotton releases the collected water by itself, as it gets warmer. (2013-01-21)

How does one sex grow larger than the other?
In most arthropod groups females are larger and therefore grow faster, a pattern markedly different from primates and birds, which showed differences in growth period. One explanation of why females can grow faster is that, although it is generally cheaper to produce (small) sperm than (large) eggs, it may be costlier to produce male gonads and genitalia. (2007-01-29)

Hitchhiking mites can provide clues to forensic entomologists
Most forensic entomology investigations generally focus on insects such as blow flies or beetles. However, the authors of a paper published in the Journal of Medical Entomology have shown that tiny mites can reveal information as well. (2016-01-06)

Biological control of insect pests - where 'natural enemies' keep pests at bay - is saving farmers in Asia and the Pacific billions of dollars, according to University of Queensland-led research. Dr Kris Wyckhuys from UQ's School of Biological Sciences said biological control involved the careful release of an exotic natural enemy from a pest's native habitat. (2020-09-03)

When do male and female differences appear in the development of beetle horns
The male Japanese rhinoceros beetle, Trypoxylus dichotomus, living on Japan's main island has big horns, which are used as weapons when it fights other males for females. As such, researchers are accordingly looking for the mechanism that creates these horns. To this end, a research team at the National Institute for Basic Biology in Japan has identified sex-determining genes for this beetle, and has succeeded in identifying the timing of sex differences that appear in horn primordia. (2019-04-10)
