Published The medicine of the future could be artificial life forms



Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It sounds like a science fiction movie, but according to nanoscientists, it can—and should—happen in the future.
Published Bumblebees drop to shake off Asian hornets



Bumblebees have a remarkably successful method for fighting off Asian hornets, new research shows.
Published New type of tiny wasp comes with mysterious, cloud-like structures at ends of antennae



Fossil researchers have discovered a novel genus and species of tiny wasp with a mysterious, bulbous structure at the end of each antenna.
Published Hippos' prominent tusks and wide gaping mouths prevent efficient, grinding chewing



Hippos' huge tusks and wide gape restrict grinding jaw movements, making their chewing inefficient, according to a new study.
Published Scientists develop 3D printing method that shows promise for repairing brain injuries



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.
Published Graphene oxide reduces the toxicity of Alzheimer's proteins



A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death, and are commonly found in the brains of Alzheimer’s patients. Researchers have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after being treated with graphene oxide nanoflakes.
Published Unique voice print in parrots



Individual voice could help birds be recognized in a flock, no matter what they say.
Published Bioengineering breakthrough increases DNA detection sensitivity by 100 times



Researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
Published Study on mysterious Amazon porcupine can help its protection



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.
Published Small but mighty new gene editor



A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published Skin behind the ears and between the toes can host a collection of unhealthy microbes



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.
Published Solving a sticky, life-threatening problem



Researchers have zeroed in on C. auris' uncanny ability to stick to everything from skin to catheters and made a startling discovery: it uses a protein similar to that used by barnacles and mollusks.
Published A deep look into the progression of Parkinson's Disease



Scientists have used cutting-edge imaging techniques to shed light on the progression of Parkinson's disease by studying how the main culprit, the protein alpha-synuclein, disrupts cellular metabolism.
Published Polyps as pixels: Innovative technique maps biochemistry of coral reefs



Using an innovative new approach to sampling corals, researchers are now able to create maps of coral biochemistry that reveal with unprecedented detail the distribution of compounds that are integral to the healthy functioning of reefs.
Published An advance in cryo-EM could be a significant boon for research on potential cancer therapies



A technology called cryo-electron microscopy enables scientists to see the atomic structure of biological molecules in high resolution. But to date, it has been ineffective for imaging small molecules. A team of biochemists devised a solution that makes it possible to hold small protein molecules in place while they're being imaged, which will enable cryo-EM to produce much clearer images of such molecules. The advance is significant because small and medium-sized protein molecules are an area of focus in research on potential new drugs for cancer and other diseases.
Published Wild Asian elephants display unique puzzle solving skills



A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
Published Boo to a goose -- new animal behaviour tech aims to save wildlife



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.
Published Toxic formaldehyde's dual nature to be probed with new chemical tool



Newly developed ompounds aim to reveal the dual nature of formaldehyde, a chemical that is known to cause cancer but is also believed to play important roles in our biology.
Published Why are killer whales harassing and killing porpoises without eating them?



For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published Whales Around the World Play With Kelp Clumps



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.
