Israel can expect a major earthquake of 6.5 on the Richter scale in the coming years
2021-01-06
A first-of-its-kind study conducted under the bed of the Dead Sea reveals that a devastating earthquake measuring 6.5 on the Richter scale is expected to hit our region in the coming years. The study showed that an earthquake of this magnitude occurs in the land of Israel on an average cycle of between 130 and 150 years, but there have been cases in history where the lull between one earthquake and another was only a few decades long.
The last earthquake with a magnitude of 6.5 on the Richter scale was felt in the Dead Sea valley in 1927, when hundreds of people were injured in Amman, Jerusalem, Bethlehem and even Jaffa. Now, in the wake of the findings ...
Gut microbe may promote breast cancers
2021-01-06
A microbe found in the colon and commonly associated with the development of colitis and colon cancer also may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy. Breast tissue cells exposed to this toxin retain a long-term memory, increasing the risk for disease.
In a series of laboratory experiments, researchers discovered that when enterotoxigenic Bacteroides fragilis (ETBF) was introduced to the guts or breast ducts of mice, it always induced growth and metastatic progression of tumor cells. A description of the work is published in the January 6 issue of the journal Cancer Discovery.
While microbes are known to be present in ...
Advancing the study of T cells to improve immunotherapy
2021-01-06
DALLAS - Jan. 6, 2020 - UT Southwestern scientists have developed a new method to study the molecular characteristics of T cells, critical immune cells that recognize and attack invaders in the body such as viruses, bacteria, and cancer.
The approach, described today in the journal Nature Methods, enables researchers to more easily analyze the roles of T cell receptors (TCRs) - the molecules on the surfaces of T cells that are responsible for recognizing pathogens.
"This could lead to a better understanding of how T cells work as well as new ways to harness T cells to fight disease," ...
Long-term study finds dozens of new genetic markers associated with lifetime bone growth
2021-01-06
Philadelphia, January 6, 2021 - A multidisciplinary team of researchers led by Children's Hospital of Philadelphia (CHOP) has discovered several genetic markers associated with bone mineral accrual, which could ultimately help identify causes of eventual osteoporosis earlier in life through genetic testing. The findings, which were made possible by following a group of children over several years, were published online by the journal Genome Biology.
Osteoporosis is widely considered a disease of old age. However, the accrual of bone density early in life is critical for achieving optimal bone mass in adulthood ...
A prognostic Alzheimer's disease blood test in the symptom-free stage
2021-01-06
Using a blood test, a German-Dutch research team has predicted the risk of Alzheimer's disease in people who were clinically diagnosed as not having Alzheimer's disease but who perceived themselves as cognitively impaired (Subjective Cognitive Declined, SCD). The researchers analyzed blood samples from an SCD cohort supervised at the Alzheimer Center Amsterdam. Using a test developed at Ruhr-Universität Bochum (RUB) called the Immuno-Infrared Sensor, they identified all 22 subjects at study entry who developed Alzheimer's dementia, thus the clinical symptoms, within six years. The test ...
Why we use our smartphone at cafés
2021-01-06
Maybe you're like us. We're the folks who are on our smartphones almost all the time, even when we're with others. We know it annoys a lot of people, but we do it anyway. Why?
Researchers at the Norwegian University of Science and Technology (NTNU) have looked at why people in cafés pull out their phones, and how this affects café life. Three main reasons they identified are: to delay or pause a conversation (interaction suspension); to get out of a conversation (deliberately shielding interaction); and to share something with others (accessing shareables).
But what does that actually mean?
The smartphone is the world's most ubiquitous personal tech gizmo. ...
How can we help victims of torture?
2021-01-06
Post-traumatic stress disorder, or PTSD, affects many people who are exposed to extreme situations, such as torture. Recent research suggests that chronic pain may make it more difficult to treat trauma.
"Trauma-focused therapy is effective for many patients with PTSD, enabling them to talk through the trauma they experienced", according to Iselin Solerød Dibaj, a psychologist at Oslo University Hospital.
However, not everyone benefits equally from this form of therapy.
"Torture victims who struggle with both chronic pain and PTSD unfortunately often reap less benefit from ordinary treatment," says Dibaj.
The Red Cross estimates that between 10 000 and 35 000 people with a refugee background who have come to Norway have experienced torture, reflecting ...
Businesses stand to benefit from sustainable restructuring
2021-01-06
The Earth is populated by an increasing number of people who demand more and more products, which is simply not viable in the long run. Our planet does not have unlimited resources. Emissions are harming the environment in various ways.
More companies thus need to switch to more sustainable production, sometimes due to pressure from consumers, but often resulting from new rules imposed by the authorities.
But this kind of change can't ever pay off - or can it?
A new study by a research group from the Norwegian University of Science and Technology (NTNU) has reviewed 100 articles on how sustainably oriented innovation affects companies' competitiveness.
"The ...
Detecting CRISPR/Cas gene doping
2021-01-06
All athletes want to be at the top of their game when they compete, but some resort to nefarious approaches to achieve peak muscle growth, speed and agility. Recent developments in gene editing technology could tempt athletes to change their DNA to get an edge. Now, researchers reporting in ACS' Analytical Chemistry demonstrate first steps toward detecting this type of doping both in human plasma and in live mice.
The gene editing method called CRISPR/Cas is a popular way for scientists to precisely change the DNA in many organisms, and it recently gained even more attention when key developers of the method were awarded the 2020 Nobel Prize in Chemistry. With this method, researchers add an RNA molecule and a protein into cells. The RNA molecule guides the protein to the appropriate ...
A better pen-and-ink system for drawing flexible circuits
2021-01-06
Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, scientists report in ACS Applied Electronic Materials that they have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to "write" circuits almost anywhere -- even on human skin.
Flexible electronics are widely used in applications such as biosensors, electronic skin and energy storage. Recent advances to produce such devices include pens ...
How Earth's oddest mammal got to be so bizarre
2021-01-06
Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes. Now, an international team of researchers led by University of Copenhagen has conducted a unique mapping of the platypus genome and found answers regarding the origins of a few of its stranger features.
It lays eggs, but nurses, it is toothless, has a venomous spur, has webbed feet, fur that glows and has 10 sex chromosomes. Ever since Europeans discovered the platypus in Australia during ...
Researchers turn coal powder into graphite in microwave oven
2021-01-06
Using copper foil, glass containers and a conventional household microwave oven, University of Wyoming researchers have demonstrated that pulverized coal powder can be converted into higher-value nano-graphite.
The discovery is another step forward in the effort to find alternative uses for Wyoming's Powder River Basin coal, at a time when demand for coal to generate electricity is declining due to concerns about climate change.
In a paper published in the journal Nano-Structures & Nano-Objects, the UW researchers report that they created an environment in a microwave oven to successfully convert raw coal powder into nano-graphite, which is ...
'Sniffing out' fruity thiols in hoppy beers
2021-01-06
Hoppy beers such as pale ales are becoming increasingly popular. One reason is their pleasant fruity aroma that partially stems from compounds called thiols. Brewers have been looking for an accurate way to track thiols in beer, but current methods typically are not sensitive enough or require use of potentially harmful substances. Now, researchers in ACS' Journal of Agricultural and Food Chemistry present an automated, solvent-less process to assess thiols at very low concentrations.
Thiols, along with other compounds such as terpenes and esters, contribute to the enjoyable odors in "hop-forward" beer styles. Although very small amounts ...

HKUST researchers discover a novel mechanism of recruiting ARF family proteins to specific subcellul
2021-01-06
The small GTPases of the ADP-ribosylation factor (Arf) family are key initiators of various physiological processes including secretion, endocytosis, phagocytosis and signal transduction. Arf family proteins function to mediate recruitment of cytosolic effectors to specific subcellular compartments. This process facilitates Arf effectors to perform cargo recognition, lipid modification or other cellular functions. Blocking the activities of Arf family proteins inhibits secretion of important molecules from the cell and also inhibits cellular uptake of nutrients. Defects in Arfs or their regulatory proteins are related to various inherited diseases, including X-linked intellectual disability (XLID), Joubert syndrome, Bardet-Biedl syndrome and cilia dysfunction. Thus, studying molecular ...
2D CaCl crystals with +1 calcium ions displaying unexpected metallicity and ferromagnetism
2021-01-06
Calcium ions are presented in rocks, bones, shells, biominerals, geological deposits, ocean sediments, and many other important materials. Calcium ions also play major roles in the retention of carbon dioxide in natural waters, water hardness, signal transduction and tissue generation. As one of the alkaline earth metals, the calcium atom has two valence electrons according to the octet rule. Up to now, the only known valence state of calcium ions under ambient conditions is +2, and the corresponding crystals with calcium ions are insulating.
By using cryo-electron ...
New review says the ineffective 'learning styles' theory persists in education
2021-01-06
A new review by Swansea University reveals there is widespread belief, around the world, in a teaching method that is not only ineffective but may actually be harmful to learners.
For decades educators have been advised to match their teaching to the supposed 'learning styles' of students. There are more than 70 different classification systems, but the most well-known (VARK) sees individuals being categorised as visual, auditory, read-write or kinesthetic learners.
However, a new paper by Professor Phil Newton, of Swansea University Medical School, highlights that this ineffective approach is still believed by teachers and calls for a more evidence-based approach to teacher-training.
He explained that various reviews, carried out since the mid-2000s, have concluded there is no ...
Analysis of SARS-CoV-2 immune response several months post-infection hints at protective immunity
2021-01-06
Researchers who studied antibody and immune cell responses in more than 180 men and women who had recovered from COVID-19 report these patients' immune memory to the virus - across all immune cell types studied - was measurable for up to 8 months after symptoms appeared. The results indicate "that durable immunity against secondary COVID-19 disease is a possibility in most individuals," the authors say. As the number of daily COVID-19 cases worldwide continues to mount, whether an initial infection with SARS-CoV-2 leads to long-lasting protective immunity against COVID-19 remains a question. Studying the nature of the humoral response to the virus, which ...

Sexual dysfunction hits some women harder than others as they age
2021-01-06
CLEVELAND, Ohio (January 5, 2021)--Sexual dysfunction often accompanies the menopause transition. Yet, not all women experience it the same. A new study identified the determinants that affect a woman's risk of sexual dysfunction and sought to determine the effectiveness of hormone therapy in decreasing that risk and modifying sexual behavior. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
Although hot flashes easily rank as the most common symptom of menopause, the transition is often accompanied by other issues, including changes that affect a woman's ...
Link between dietary fiber and depression partially explained by gut-brain interactions
2021-01-06
CLEVELAND, Ohio (January 5, 2021)--Fiber is a commonly recommended part of a healthy diet. That's because it's good for your health in so many ways--from weight management to reducing the risk of diabetes, heart disease, and some types of cancer. A new study also finds that it might be linked with a reduced risk of depression, especially in premenopausal women. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
Depression is a common and serious mental health condition that not only affects a person's ability to perform daily activities but can also lead to suicide. ...
New work provides insight into the relationship between complexity and diversity
2021-01-06
Most forms of life -- species of mammals, birds, plants, reptiles, amphibians, etc. -- are most diverse at Earth's equator and least diverse at the poles. This distribution is called the latitudinal gradient of biodiversity.
A group of Santa Fe Institute collaborators was intrigued by the fact that human cultural diversity shows exactly the same distribution with latitude: human cultures are more diverse near the equator and least at the poles. Their big question was: why? Life is more diverse within richer environments, but it's not clear why human cultural diversity would show this pattern too.
To find answers, the group conducted a biogeographic and macroecological study of the distribution of mammal species ...
COVID-19 generally 'mild' in young children: Evidence review
2021-01-06
A systematic review and meta-analysis of international COVID-19 literature, led by UNSW Sydney, has confirmed that while children under five years old were likely to recover from the infection, half of those infected were infants and almost half of the infected under-fives were asymptomatic.
These findings will help to inform future policy and decision-making about potential COVID-19 vaccination for young children and maternal immunisation programs during pregnancy - but the scientists say future research is needed to explore the potential risk of transmission from infants to their mothers, families and other caregivers, and to find out more about whether asymptomatic under-fives can spread the disease.
The collaborative study between researchers from UNSW Sydney, Telethon ...
