Observing mammalian cells with superfast soft X-rays      (via sciencedaily.com)     Original source 

Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.

Psychedelic drug-induced hyperconnectivity in the brain helps clarify altered subjective experiences      (via sciencedaily.com)     Original source 

A new study shows that the use of psilocybin, a compound found in the widely known 'magic mushrooms,' initiates a pattern of hyperconnectivity in the brain linked to the ego-modifying effects and feelings of oceanic boundlessness. The findings help explain the so-called mystical experiences people report during the use of psychedelics and are pertinent to the psychotherapeutic applications of psychedelic drugs to treat psychiatric disorders such as depression.

Designing a better nest to help endangered turtles      (via sciencedaily.com)     Original source 

With Ontario's eight species of turtles considered at risk, a new nest designed by researchers has the potential to significantly bolster their struggling populations. The habitat is the first designed for turtles in rock barren landscapes, such as the research site around Georgian Bay. It uses moss and lichen. The researchers found that the design provided a more stable environment for incubating eggs compared to natural sites, where the probability of an egg hatching was only 10 per cent compared to 41 per cent in the created site.

Birdsong and human voice built from same genetic blueprint      (via sciencedaily.com)     Original source 

Humans have been long fascinated by bird song and the cacophony of other avian sounds -- from coos and honks to quacks and peeps. But little is known about how the unique vocal organ of birds -- the syrinx -- varies from species to species or its deeper evolutionary origins. A trio of recent studies is changing that. The studies include high-resolution anatomical scans of syrinxes from hummingbirds and ostriches -- the world's smallest and largest bird species -- and the discovery that the syrinx and larynx, the vocal organ of reptiles and mammals, including humans, share the same developmental programming.

Novel approach to interrogate tissue-specific protein-protein interactions      (via sciencedaily.com)     Original source 

Multicellular organisms, like animals and plants, have complex cells with diverse functions. This complexity arises from the need for cells to produce distinct proteins that interact with each other. This interaction is crucial for cells to carry out their specific tasks and to form complex molecular machinery. However, our current understanding of such protein-protein interactions often lacks cellular contexts because they were usually studied in an in vitro system or in cells isolated from their tissue environment. Effective methods to investigate protein-protein interactions in a tissue-specific manner are largely missing.

Tracking down the genetic causes of lupus to personalize treatment      (via sciencedaily.com)     Original source 

Treatment of autoimmune diseases like lupus has long relied on steroids to knock down the immune system, but more targeted therapies are currently undergoing clinical trials. To make sure these therapies get to the patients who will benefit, work is needed to identify the specific mutations behind each patient's disease. Researchers now report several dozen mutations associated with oversensitive toll-like receptors -- a major cause of autoimmune disease -- and linked two mutations to patients.

Sexual parasitism helped anglerfish invade the deep sea during a time of global warming      (via sciencedaily.com)     Original source 

Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.

Exploring diversity in cell division      (via sciencedaily.com)     Original source 

Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine protists that are close relatives of both animals and fungi -- use either open and closed mitosis, closely correlated to whether the species has multinucleate life cycle stages. The study demonstrates the way animals do cell division might have evolved long before animals themselves did and how this is linked to an organism's life cycle.

Sweet move: a modified sugar enhances antisense oligonucleotide safety and efficacy      (via sciencedaily.com)     Original source 

Researchers found that adding a newly developed modified sugar, BNAP-AEO, to gapmer antisense oligonucleotides (ASOs) increased their affinity for target RNAs, thus significantly enhancing their gene-silencing effects in vitro and in vivo. The BNAP-AEO modification also decreased gapmer ASO toxicity to the central nervous system (CNS), suggesting that it could improve the clinical application of ASO treatment of CNS disease.

Study finds widespread 'cell cannibalism,' related phenomena across tree of life      (via sciencedaily.com)     Original source 

Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals.
