Fragrance helps learning even during sleep!
Effortless learning during sleep is the dream of many people. The supportive effect of smells on learning success when presented both during learning and sleep was first proven in an extensive sleep laboratory study. Researchers at the University of Freiburg—Medical Center, the Freiburg Institute for Frontier Areas of Psychology and Mental Health (IGPP) and the Faculty of Biology at the University of Freiburg have now shown that this effect can be also achieved very easily outside the lab. For the study, pupils in two school classes learned English vocabulary—with and without scent sticks during the learning period and also at night. The students remembered the vocabulary much better with a scent. The study was published in the Nature Group’s Open Access journal Scientific Reports on 27 January 2020.
“We showed that the supportive effect of fragrances works very reliably in everyday life and can be used in a targeted way,” said study leader PD Dr. Jürgen Kornmeier, head of the Perception and Cognition Research Group at the Freiburg-based IGPP and scientist at the Department of Psychiatry and Psychotherapy at the University of Freiburg—Medical Center in Germany.
The smell of roses when learning and sleeping
For the study, first author and student teacher Franziska Neumann conducted several experiments with 54 students from two 6th grade classes of a school in southern Germany. The young participants from the test group were asked to place rose-scented incense sticks on their desks at home while learning English vocabulary and on the bedside table next to the bed at night. In another experiment, they also placed the incense sticks on the table next to them during a vocabulary test at school during an English test. The results were compared with test results in which no incense sticks were used during one or more phases.
The drug, known as DSP-1181, was created by using algorithms to sift through potential compounds, checking them against a huge database of parameters, including a patient’s genetic factors. Speaking to the BBC, Exscientia chief executive Professor Andrew Hopkins described the trials as a “key milestone in drug discovery” and noted that there are “billions” of decisions needed to find the right molecules for a drug, making their eventual creation a “huge decision.” With AI, however, “the beauty of the algorithm is that they are agnostic, so can be applied to any disease.”
We’ve already seen multiple examples of AI being used to diagnose illness and analyze patient data, so using it to engineer drug treatment is an obvious progression of its place in medicine. But the AI-created drugs do pose some pertinent questions. Will patients be comfortable taking medication designed by a machine? How will these drugs differ from those developed by humans alone? Who will make the rules for the use of AI in drug research? Hopkins and his team hope that these and myriad other questions will be explored in the trials, which will begin in March.

Tigers and their close relatives (Panthera) are some of the world’s most endangered species. Here we report the de novo assembly of an Amur tiger whole-genome sequence as well as the genomic sequences of a white Bengal tiger, African lion, white African lion and snow leopard. Through comparative genetic analyses of these genomes, we find genetic signatures that may reflect molecular adaptations consistent with the big cats’ hypercarnivorous diet and muscle strength. We report a snow leopard-specific genetic determinant in EGLN1 (Met39Lys39), which is likely to be associated with adaptation to high altitude. We also detect a TYR 260GA mutation likely responsible for the white lion coat colour. Tiger and cat genomes show similar repeat composition and an appreciably conserved synteny. Genomic data from the five big cats provide an invaluable resource for resolving easily identifiable phenotypes evident in very close, but distinct, species.
Regenerative medicine and furthermore tissue engineering are realities for some time but well hidden from the public by msm somehow.

“It regenerates almost anything after almost any injury that doesn’t kill it,” said Parker Flowers, postdoctoral associate in the lab of Craig Crews, the John C. Malone Professor of Molecular, Cellular, and Developmental Biology and professor of chemistry and pharmacology.
If scientists can find the genetic basis for the axolotl’s ability to regenerate, they might be able to find ways to restore damaged tissue in humans. But they have been thwarted in the attempt by another peculiarity of the axolotl — it has the largest genome of any animal yet sequenced, 10 times larger than that of humans.
Now Flowers and colleagues have found an ingenious way to circumvent the animal’s complex genome to identify at least two genes involved in regeneration, they report Jan. 28 in the journal eLife.
Do you think Xenobots is the early stage of nanobots, which could repair our body to achieve longevity escape velocity?
Scientists have created the world’s first living, self-healing robots using stem cells from frogs.
Named xenobots after the African clawed frog (Xenopus laevis) from which they take their stem cells, the machines are less than a millimeter (0.04 inches) wide — small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups.
These are “entirely new life-forms,” said the University of Vermont, which conducted the research with Tufts University’s Allen Discovery Center.
When Mina Jang played the same melodious tune on two different flutes behind a screen, she said the examiners grading her couldn’t tell the difference.
Yet the two instruments were made in dramatically different ways.
One was a handmade version of an original early 18th-century flute crafted in 2001, while the other was made of white plastic and “cloned” using a 3D printer in 2019.
