Meadow Spittlebug's record-breaking diet also makes it top disease carrier for plants      (via sciencedaily.com)     Original source 

New research fueled in part by citizen scientists reveals that the meadow spittlebug—known for the foamy, spit-like urine released by its nymphs—can feed on at least 1,300 species of host plants, more than twice the number of any other insect.

Extreme fires and heavy rainfall driving platypuses from their homes      (via sciencedaily.com)     Original source 

Australia's emerging pattern of severe mega bushfires and heavy rainfall may be driving platypuses from their homes, a new study has shown. Analysis of platypus DNA in rivers and creek water samples collected before and after the Black Summer 2019-2020 megafires suggest Australia's beloved semi-aquatic monotremes might be abandoning severely bushfire-affected areas for up to 18 months after a fire, especially if heavy rainfall has followed the fire.

Scientists develop 3D printing method that shows promise for repairing brain injuries      (via sciencedaily.com)     Original source 

Researchers have produced an engineered tissue representing a simplified cerebral cortex by 3D printing human stem cells. When implanted into mouse brain slices, the structures became integrated with the host tissue. The technique may ultimately be developed into tailored repairs to treat brain injuries.

Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say      (via sciencedaily.com)     Original source 

The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.

Study on mysterious Amazon porcupine can help its protection      (via sciencedaily.com)     Original source 

A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.

Timing plant evolution with a fast-ticking epigenetic clock      (via sciencedaily.com)     Original source 

Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.

Skin behind the ears and between the toes can host a collection of unhealthy microbes      (via sciencedaily.com)     Original source 

Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.

Boo to a goose -- new animal behaviour tech aims to save wildlife      (via sciencedaily.com)     Original source 

Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.

A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.

How to save plants from climate change? Just ask them      (via sciencedaily.com) 

Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.
