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 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

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.
32 salmonella cases in 6 provinces tied to pet hedgehogs
Four people have been hospitalized and 28 others made ill from outbreaks of salmonella infections in six provinces caused by exposure to pet hedgehogs, the Public Health Agency of Canada...
US official says every American who wants a covid-19 vaccine will have one by June
An official with the US covid-19 vaccine initiative says anyone in the country who wants a vaccine will be able to have it by June, seven months from now.
The confident projection was made by retired Lieutenant General Paul Ostrowski, director of supply, production, and distribution for Operation Warp Speed, during an appearance on MSNBC on Monday, November 30.

New method sees fibers in 3-D, uses it to estimate conductivity
As a vehicle travels through space at hypersonic speeds, the gases surrounding it generate heat at dangerous temperatures for the pilot and instrumentation inside. Designing a vehicle that can drive the heat away requires an understanding of the thermal properties of the materials used to construct it. A recent two-part study at the University of Illinois Urbana-Champaign developed a method to...
Molecule that regulates muscle adaptation to exercise is discovered
The onset of any physical exercise program causes muscle pain that can hinder movements as simple as getting up from a sofa. With time and a little persistence, the muscles become accustomed to the effort, developing more strength and endurance. Researchers affiliated with Harvard University in the United States and the University of São Paulo (USP) in Brazil describe the cellular mediator that...
Geoscientists use zircon to trace origin of Earth's continents
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.
Graphene: The building block for sustainable cities
Innovation in advanced materials offers the disruptive potential to transform the way we build our future cities—and make them greener and smarter.
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).

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.
How to spot winning sperm: Examine their racing stripes
Millions of sperm enter the race to fertilize, but only one wins the sprint to the egg.
Stimulus relief funds increase social distancing to stop spread of COVID-19
As case rates of COVID-19 reach new heights across the nation, many states and cities are tightening stay-at-home restrictions to stop the spread. New research suggests that that those suffering from economic hardships are less likely comply with new stay-at-home orders; however, these same U.S. residents would be more likely to adhere to the new public health guidelines if their households...

Study suggests metabolism influences parasite's resistance to drugs
New insight on how a parasite can resist current therapies has been published today in the open-access eLife journal.
Seismic activity of New Zealand's alpine fault more complex than suspected
A rupture along the full length of the fast-slipping Alpine Fault on New Zealand's South Island poses the largest potential seismic threat to the southern and central parts of the country. But new evidence of a 19th century earthquake indicates that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events.
Tomato's wild ancestor is a genomic reservoir for plant breeders
Thousands of years ago, people in South America began domesticating Solanum pimpinellifolium, a weedy plant with small, intensely flavored fruit. Over time, the plant evolved into S. lycopersicum—the modern cultivated tomato.

Mapping stellar nurseries in the Milky Way
An international team of Astronomers from the Cosmostatistics Initiative (COIN) identified nearly 120,000 new young stellar objects (YSOs) based on data from the Infrared Array Camera of NASA's Spitzer Space Telescope. The final catalog, named SPICY (Spitzer/IRAC Candidate YSO Catalog), is publicly available to anyone who wishes to study the first stages of stellar development.
Noble False Widow spider bite can transmit harmful antibiotic resistant bacteria to humans
A team of zoologists and microbiologists from NUI Galway 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.
