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.

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.

Mistaken identity cleared up of foodborne pathogen causing severe symptoms in children      (via sciencedaily.com)     Original source 

Researchers have developed a quantitative real-time PCR-based detection method for the emerging zoonotic organism Escherichia albertii. They found that E. albertii survives in the human intestinal tract for about four weeks at least.

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.

Eating more ultra-processed foods tied to cognitive decline, stroke, according to study      (via sciencedaily.com)     Original source 

People who eat more ultra-processed foods like soft drinks, chips and cookies may have a higher risk of having memory and thinking problems and having a stroke than those who eat fewer processed foods, according to a new study. The study does not prove that eating ultra-processed foods causes memory and thinking problems and stroke. It only shows an association.

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.

Excavation reveals 'major' ancient migration to Timor Island      (via sciencedaily.com)     Original source 

The discovery of thousands of stone artefacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists.

Roots are a key to drought-tolerant maize      (via sciencedaily.com)     Original source 

Maize can grow successfully in very different local conditions. An international study has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably -- depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in the plant's ability to adapt. This gene could be the key to developing varieties of maize that cope better with climate change.

Cuddled cows who work as therapy animals showed a strong preference for women compared to men, study finds      (via sciencedaily.com)     Original source 

A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.
