Galactic cosmic rays affect Titan's atmosphere

Planetary scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) revealed the secrets of the atmosphere of Titan, the largest moon of Saturn. The team found a chemical footprint in Titan's atmosphere indicating that cosmic rays coming from outside the Solar System affect the chemical reactions involved in the formation of nitrogen-bearing organic molecules. This is the first observational confirmation of such processes, and impacts the understanding of the intriguing environment of Titan.

Status update: OSIRIS-REx Osprey Flyover

NASA's OSIRIS-REx spacecraft safely executed a 0.4-mile (620-m) flyover of the backup sample collection site Osprey as part of the mission's Reconnaissance B phase activities. Preliminary telemetry, however, indicates that the OSIRIS-REx Laser Altimeter (OLA) did not operate as expected during the 11-hour event. The OLA instrument was scheduled to provide ranging data to the spacecraft's PolyCam imager, which would allow the camera to focus while imaging the area around the sample collection site. Consequently, the PolyCam images from the flyover are likely out of focus.

Technology news

Microelectronics embedded in live jellyfish enhance propulsion

Researchers in robotic materials aim to artificially control animal locomotion to address the existing challenges to actuation, control and power requirements in soft robotics. In a new report in Science Advances, Nicole W. Xu and John O. Dabiri at the departments of bioengineering, civil and environmental engineering and mechanical engineering at the Stanford University presented a biohybrid robot that used onboard microelectronics to induce swimming in live jellyfish. They measured the ability to substantially enhance propulsion by driving body contractions at an optimal frequency range faster than natural behavior. The manoeuvre increased swimming speed by nearly threefold, although with only a twofold increase in metabolic expenditure of the animal and 10 mW of external power input to the microelectronics. The biohybrid robot used 10 to 1000 times less external power per mass than with previously reported aquatic robots. The capability can improve the performance scope of biohybrid robots relative to native performance, with potential applications as biohybrid ocean monitoring robots.

Stubborn strain of Android malware disses resets

Key modifier found in genetic deletion related to neurodevelopmental disorders

Neurodevelopmental disorders, including schizophrenia and autism, likely result from complex interactions that modify the effects of individual genes. In a new study, researchers evaluated the effects of over 300 pairwise knockdowns—reducing the expression of two genes simultaneously—of the fruit fly versions of genes located in a region of human chromosome 3 that, when deleted, has been implicated in these disorders. These interactions suggest that the disorders have a complex causation involving many genes, rather than resulting from the effects of any individual gene. One gene in particular, NCBP2, appears to be a key modifier, influencing the impact of other genes in the deletion.

Designing artificial brains can help us learn more about real ones

Despite billions of dollars spent and decades of research, computation in the human brain remains largely a mystery. Meanwhile, we have made great strides in the development of artificial neural networks, which are designed to loosely mimic how brains compute. We have learned a lot about the nature of neural computation from these artificial brains and it's time to take what we've learned and apply it back to the biological ones.

Could leukemia be stopped before it starts?

Acute myeloid leukemia (AML), a blood cancer affecting both adults and children, requires more than one genetic "hit" to develop. As we age, many of us acquire a mutation that enables certain of our blood cells to multiply faster than others, forming their own distinct population. This first hit, known as "clonal hematopoiesis of indeterminate potential," or CHIP, isn't necessarily harmful.

Researchers were not right about left brains

The left and right sides of the human brain are specialized for some cognitive abilities. For example, in humans, language is processed predominantly in the left hemisphere, and the right hand is controlled by the motor cortex in the left hemisphere. The functional lateralization is reflected by morphological asymmetry of the brain. Left and right hemisphere differ subtly in the distribution of nerve cells, their connectivity and neurochemistry.

'Quit vaping searches increased during lung-disease outbreak

E-cigarettes have been sold for more than a decade, seemingly without incident, but in the summer of 2019 serious lung injuries began appearing among some e-cigarette users—especially adolescents and young adults. By last January of 2020, the Centers for Disease Control and Prevention reported more than 2,700 hospitalizations for EVALI, or e-cigarette or vaping product use-associated lung injury, and confirmed 60 deaths in 27 states with more under investigation. The cases have now been linked primarily vaping of marijuana and additives, but before this was discovered, many people using nicotine-containing e-cigarettes became concerned.

How early life trauma can contribute to functional neurological disorder

In individuals with functional neurological disorder (FND), the brain generally appears structurally normal on clinical MRI scans but functions incorrectly (akin to a computer software crashing), resulting in patients experiencing symptoms including limb weakness, tremor, gait abnormalities and non-epileptic seizures. In some cases, childhood maltreatment may have been a contributing factor, yet links between risk factors such as childhood abuse and brain mechanisms for the development of FND remain poorly understood. In a new study published in Molecular Psychiatry, researchers led by investigators at Massachusetts General Hospital (MGH) examined the brains of individuals who experienced early-life trauma, some with FND and others without the condition. The findings may provide a better understanding of what happens in the brains of some patients with FND, as well as those with various other trauma-related brain disorders.

Ceramides predict vascular brain injury and dementia

Novel blood-based biomarkers for dementia could identify disease at an early preclinical stage, serve as surrogate outcomes for clinical trials of investigational therapies and even identify future potential therapeutic targets. Unlike cerebrospinal fluid biomarkers that require a spinal tap, plasma biomarkers can be extracted from the blood, making their collection much less invasive and much more appealing for patients. In a study published in Annals of Clinical and Translational Neurology, a team led by investigators from Brigham and Women's Hospital describes the role of plasma ceramides in dementia and Alzheimer's disease (AD) and their potential as a blood-based biomarker.

Some bariatric surgery patients don't sense heightened blood alcohol levels

Researchers use new method to investigate neural oscillations

Neural oscillations—also known as brainwaves—are important carriers of information in the brain. Researchers are increasingly coming to view them less as sustained oscillations and more as transient bursts. Until now, there has been no method for measuring such short-lived bursts in real time or for examining how they influence the behavior of living things. In cooperation with her working group, Prof. Dr. Ilka Diester of the University of Freiburg's Institute of Biology III and excellence cluster BrainLinks-BrainTools has developed a new method for analyzing data in the brain. They are using their method to detect short beta wave bursts in real time within neural frequency bands of around 20 Hertz and to show how rats can increase the occurrence of these bursts. The researchers have published their results in the scientific journal Nature Communication Biology.

Our memory prefers essence over form

What clues does our memory use to connect a current situation to a situation from the past? The results of a study conducted by researchers from the University of Geneva (UNIGE), Switzerland—working in collaboration with CY Cergy Paris University in France—contrast sharply with the explanations found until now in the existing literature. The researchers have demonstrated that similarities in structure and essence (the heart of a situation) guide our recollections rather than surface similarities (the general theme, for example, or the setting or protagonists). It is only when individuals lack sufficient knowledge that they turn to the surface clues—the easiest to access—to recollect a situation. These results, published in the journal Acta Psychologica, are particularly relevant in the field of education. They underline the need to focus on the conceptual aspects of situations that are tackled in class to help pupils make use of the relevant features, and not to be misled by apparent similarities.

Gold nanoclusters: New frontier for developing medication for treatment of Alzheimer's disease

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by amyloid-β (Aβ) fibrillation and plaque formation. While more than 50 million people are devastated by AD, no treatment is available. Recently, anti-Aβ antibody-based immunotherapy has failed in clinical trials, partially due to the increased cytotoxicity of soluble Aβ oligomers. Therefore, developing a medication for AD treatment becomes an even more important challenge.

Biologists investigate the role of the largest animal brain cells

The brains of most fish and amphibian species contain two types of conspicuously large nerve cells. These are the largest cells found in any animal brain. They are called Mauthner cells and trigger lightning-fast escape responses when predators approach. Biologists at the University of Bayreuth have now shown that these cells have unique functions essential for survival, the loss of which cannot be compensated for by other nerve cells. In addition, they have discovered that Mauthner cells remain functional for a long time without their cell bodies (soma). The researchers have published their findings in the journal Proceedings of the National Academy of Sciences.

Transparent human organs allow 3-D maps at the cellular level

For the first time, researchers have managed to make intact human organs transparent. Using microscopic imaging, they revealed complex underlying structures of the transparent organs at the cellular level. The resulting organ maps can serve as templates for 3-D bioprinting technologies. In the future, this could lead to the creation of on-demand artificial organs for many patients in need. The findings have been published in Cell.

Leaking away essential resources actually helps cells grow

Experts have been unable to explain why cells, from bacteria to humans, leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites—substances involved in the chemical processes to sustain life with production of complex molecules and energy—may provide cells both selfish and selfless benefits.

Physically producing computer-generated artificial genomes to understand DNA

The molecular blueprint of life is stored in DNA within the genome. The digital revolution in biology, driven by DNA sequencing, enables scientists to read the genomes of the many microbes and multicellular organisms that populate our world.

Cryo-electron microscopy opens a door to fight Epstein-Barr

The Epstein-Barr virus is one of the most widespread human viruses. Part of the herpesvirus family, it causes glandular fever (infectious mononucleosis), cancer and autoimmune diseases. At present, there is no treatment for infections caused by this virus. In work recently published in Nature Communications, scientists from the Institute for Research in Biomedicine (IRB Barcelona) and the Molecular Biology Institute of Barcelona (IBMB-CSIC) in Spain used cryo-electron microscopy (cryo-EM) to reveal the structure of a key protein, known as a portal, in the Epstein-Barr virus. Similarities between herpesviruses and tailed bacteriophages (viruses that infect bacteria) suggest that these two types of organism may be related. In a second paper published in the same journal, the team solved the structure of the portal protein in bacteriophage T7, using a combination of cryo-EM and X-ray crystallography. These results allowed them to infer how the Epstein-Barr virus portal works and may help in the development of a treatment for this virus.
