New mechanism underlying male infertility
- ScienceDaily
- 21/1/7 22:47
One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are antenna-like structures that protrude from most of the cells in our body, contain many microtubules. An example of flagell is the sperm tail, which is essential for male fertility and thus for sexual...
Insights into the Yellowstone hotspot
- ScienceDaily
- 21/1/7 22:47
The Yellowstone hotspot is well known for generating supereruptions in the geologic past that are far more explosive than historic examples. The origin and sustained longevity of the hotspot is less understood but is focused on two competing models, where the ascent of hot mantle is derived from either a deep-seated mantle plume or a shallow mantle source.
Cancer cells hibernate like bears to evade harsh chemotherapy
- ScienceDaily
- 21/1/7 22:47
Researchers show that cancer cells hijack an evolutionary conserved program to survive chemotherapy. Furthermore, the researchers show that novel therapeutic strategies aimed at specifically targeting cancer cells in this slow-dividing state can prevent cancer regrowth.
Mysterious family life of notorious saber-toothed tiger

Functional seizures associated with stroke, psychiatric disorders
- ScienceDaily
- 21/1/7 19:57
In a large-scale study of electronic health records investigators determined the prevalence of functional seizures and characterized comorbidities associated with them. Functional seizures are sudden attacks or spasms that look like epileptic seizures but do not have the aberrant brain electrical patterns of epilepsy. The research team confirmed associations between functional seizures and...
Emotionally appealing ads may not always help consumer memory

Emotional appeals in advertisements may not always help improve consumers' immediate recall of a product, says a new article.
What is surgical smoke and what can be done about it?
- ScienceDaily
- 21/1/7 19:57
Surgical smoke poses a health risk to everyone in the operating room. Perioperative teams exposed to surgical smoke report twice as many respiratory health issues as the general public. The smoke can even contain viruses. Researchers suggest that policies and laws mandating the evacuation of surgical smoke from operating rooms are the best way to reduce the negative health impacts on perioperative...

Improving imaging processes will lead to more successful treatments and help reduce morbidity in men with the disease.
Striped or spotted? Winds and jet streams found on the closest brown dwarf
- ScienceDaily
- 21/1/7 19:56
Using high-precision brightness measurements from NASA's TESS space telescope, astronomers found that the nearby brown dwarf Luhman 16B's atmosphere is dominated by high-speed, global winds akin to Earth's jet stream system. This global circulation determines how clouds are distributed in the brown dwarf's atmosphere, giving it a striped appearance.
COVID-19 outcomes for patients on immunosuppressive drugs on par with non-immunosuppressed patients, study finds
- ScienceDaily
- 21/1/7 19:56
People taking immunosuppressive drugs to prevent organ transplant rejection or to treat inflammatory or autoimmune diseases do not fare worse than others on average when they are hospitalized with COVID-19, according to a new study.
Intelligence deficit: Conclusion from the mouse to the human being
- ScienceDaily
- 21/1/7 18:53
Impaired intelligence, movement disorders and developmental delays are typical for a group of rare diseases that belong to GPI anchor deficiencies. Researchers now used genetic engineering methods to create a mouse that mimics these patients very well. Studies in this animal model suggest that in GPI anchor deficiencies, a gene mutation impairs the transmission of stimuli at the synapses in the...
Reducing treatment-related complication for blood cancer patients
- ScienceDaily
- 21/1/7 18:53
Researchers published promising findings on preventing a common complication to lifesaving blood stem cell transplantation in leukemia.
High-flux table-top source for femtosecond hard X-ray pulses
- ScienceDaily
- 21/1/7 18:53
Researchers have now accomplished a breakthrough in table-top generation of femtosecond X-ray pulses by demonstrating a stable pulse train at kilohertz repetition rate with a total flux of some 10^12 X-ray photons per second.
What happens when your brain can't tell which way is up or down?
- ScienceDaily
- 21/1/7 18:53
What feels like up may actually be some other direction depending on how our brains process our orientation, according to psychology researchers. Researchers found that an individual's interpretation of the direction of gravity can be altered by how their brain responds to visual information.
For the right employees, even standard information technology can spur creativity
- ScienceDaily
- 21/1/7 18:53
In a money-saving revelation for organizations inclined to invest in specialized information technology to support the process of idea generation, new research suggests that even non-specialized, everyday organizational IT can encourage employees' creativity.
Protein that can be toxic in the heart and nerves may help prevent Alzheimer's
- ScienceDaily
- 21/1/7 18:53
A protein that wreaks havoc in the nerves and heart when it clumps together can prevent the formation of toxic protein clumps associated with Alzheimer's disease, a new study shows. The findings could lead to new treatments for this brain-ravaging condition, which currently has no truly effective therapies and no cure.
Mediterranean diet may decrease risk of prostate cancer progression
- ScienceDaily
- 21/1/7 18:53
In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles of a Mediterranean-style diet fared better over the course of their disease.
Delivering the news with humor makes young adults more likely to remember and share
- ScienceDaily
- 21/1/7 18:53
Could the merging of humor and news actually help inform the public? New research found that young people were more likely to remember information about politics and government policy when it was conveyed in a humorous rather than non-humorous manner. They were also more willing to share the information online.

Fundamental study on the Kondo effect
- ScienceDaily
- 21/1/7 18:52
In 1998, spectroscopic studies on the Kondo effect using scanning tunnelling microscopy were published, which are considered ground-breaking and have triggered countless others of a similar kind. Many of these studies may have to be re-examined now that researchers have shown that the Kondo effect cannot be proven beyond doubt by this method. Instead, another phenomenon is creating precisely the...
Patterns in primordial germ cell migration
- ScienceDaily
- 21/1/7 18:52
Biologists and mathematicians have investigated how primordial germ cells behave in zebrafish embryos when not influenced by a guidance cue and developed software that merges 3D microscopy images of multiple organisms. This made it possible to recognize patterns in the cell distribution and thus to highlight tissues that influence cell migration.
