Vitamin D regulates calcium in intestine differently than previously thought
- ScienceDaily
- 20/12/1 23:17
A new study has discovered that vitamin D regulates calcium in a section of the intestine that previously was thought not to have played a key role. The findings have important implications on how bowel disease, including ulcerative colitis and Crohn's disease, may disrupt calcium regulation.
New method sees fibers in 3D, uses it to estimate conductivity
- ScienceDaily
- 20/12/1 23:17
Designing a vehicle that can drive away the heat that is generated around it when traveling at hypersonic speeds requires an understanding of the thermal properties of the materials used to construct it. A recent study developed a method to create 3D models of the fibers within composite materials then used that information to predict the thermal conductivity of the material.
COVID-19 may deepen depression, anxiety, and PTSD among pregnant and postpartum women
- ScienceDaily
- 20/12/1 23:17
In a new study, researchers surveyed pregnant women and those who had recently given birth, finding concerning rates of depression, generalized anxiety and post-traumatic stress disorder (PTSD) symptoms, which were found to be exacerbated by COVID-19-related grief and health worries.
Glucosamine may reduce overall death rates as effectively as regular exercise, study suggests

Glucosamine supplements may reduce overall mortality about as well as regular exercise does, according to a new epidemiological study.
More evidence that cellular 'death by iron' could be promising avenue of cancer treatment
- ScienceDaily
- 20/12/1 23:17
Genetic mutations that give cancers a metabolic boost may also leave them vulnerable to drugs that promote a particular form of cell death, researchers have found.
How automated vehicles can impede driver performance, and what to do about it
- ScienceDaily
- 20/12/1 21:34
A new study is underscoring the importance of drivers keeping their eyes on the road -- even when they are in an automated vehicle (AV). The findings revealed that drivers can become over-reliant on AV technology. This was especially true with a type of in-vehicle display the team coined as takeover request and automation capability (TORAC).
Geoscientists use zircon to trace origin of Earth's continents
- ScienceDaily
- 20/12/1 21:34
Geoscientists have long known that some parts of the continents formed in the Earth's deep past, but the speed in which land rose above global seas -- and the exact shapes that land masses formed -- have so far eluded experts.
Researchers look to reduce rotorcraft noise
- ScienceDaily
- 20/12/1 21:34
Imagine a silent helicopter stealthily moving troops and supplies around a future battlefield. U.S. Army researchers look to helicopter noise reduction technology as a top priority in aircraft design.
Need to increase HPV vaccine uptake in adolescents
- ScienceDaily
- 20/12/1 20:41
More than 90 percent of human papillomavirus (HPV)-related cancers could be prevented by widespread uptake of the HPV vaccine. Yet, vaccine use in the United States falls short of public health goals.
What will the climate be like when Earth's next supercontinent forms?
- ScienceDaily
- 20/12/1 20:40
In roughly 200 million years, the continents will once again unite into a supercontinent. A new study explores how the next Pangea could affect the global climate.
Metabolism influences parasite's resistance to drugs
- ScienceDaily
- 20/12/1 20:40
New insight on how a parasite can resist current therapies has just been published.
How are older adults coping with the mental health effects of COVID-19?
- ScienceDaily
- 20/12/1 20:40
Recent studies indicate that older adults may be withstanding the mental health strains of the COVID-19 pandemic better than other age groups.
AI-based 'OxyGAN' is a robust, effective method to measure tissue oxygen levels
- ScienceDaily
- 20/12/1 20:40
Researchers have proposed an end-to-end technique for accurate calculation of tissue oxygenation from single snapshots, called OxyGAN.
Bleach-alternative COVID-19 surface disinfectants may pollute indoor air, study finds
- ScienceDaily
- 20/12/1 20:40
Cleaning surfaces with hydrogen peroxide-based disinfectants has the potential to pollute the air and pose a health risk, according to new research.
False widow spiders bite can transmit harmful antibiotic-resistant bacteria
- ScienceDaily
- 20/12/1 20:40
A team of zoologists and microbiologists have published a new study showing that common house spiders carry bacteria susceptible to infect people, with the Noble False Widow spiders also carrying harmful strains resistant to common antibiotic treatments.
Novel mechanisms that cause protein clumping in brain diseases
- ScienceDaily
- 20/12/1 20:40
A team of researchers has taken a major step toward understanding the mechanisms involved in the formation of large clumps of tau protein, a hallmark of Alzheimer's disease and several other neurodegenerative disorders.
Shrinking massive neural networks used to model language
- ScienceDaily
- 20/12/1 20:40
Deep learning neural networks can be massive, demanding major computing power. In a test of the 'lottery ticket hypothesis,' researchers have found leaner, more efficient subnetworks hidden within BERT models. The discovery could make natural language processing more accessible.
Researchers study influence of cultural factors on gesture design
- ScienceDaily
- 20/12/1 20:40
Freehand gesture-based interfaces in interactive systems are becoming more common, but what if your preferred way to gesture a command - say, changing the TV to channel 10 - significantly differed from that of a user from another culture? Would the system recognize your command? Researchers explored this question and found that some gesture choices are significantly influenced by the cultural...
Seismic activity of New Zealand's alpine fault more complex than suspected
- ScienceDaily
- 20/12/1 20:40
New evidence of a 19th century earthquake on New Zealand's Alpine fault suggests that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events.
Telomere shortening protects against cancer
- ScienceDaily
- 20/12/1 20:40
Researchers have found the first evidence that telomere shortening is not just a sign of aging, but a key component of the body's cancer prevention system.
Statins can save lives; are they being used?
