Unsettling currents: Warm water flowing beneath the 'Doomsday Glacier'
- ScienceDaily
- 21/4/9 20:58
Researchers have been able to obtain data from underneath Thwaites Glacier, also known as the 'Doomsday Glacier'. They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow.
Brain disease transmitted by tick bites may be treatable
- ScienceDaily
- 21/4/9 20:58
The virus that causes tick-borne encephalitis appears to trick the immune system, misdirecting it into producing inferior antibodies. But new research shows some people produce more potent antibodies, providing hope for treatment.
Using genetics, researchers identify potential drugs for early treatment of COVID-19
- ScienceDaily
- 21/4/9 18:47
A new study using human genetics suggests researchers should prioritize clinical trials of drugs that target two proteins to manage COVID-19 in its early stages. Based on their analyses, the researchers call for prioritizing clinical trials of drugs targeting the proteins IFNAR2 and ACE2. The goal is to identify existing drugs, either FDA-approved or in clinical development for other conditions,...

- 21/4/9 18:47
Psychosocial stress - typically resulting from difficulty coping with challenging environments - may work synergistically to put women at significantly higher risk of developing coronary heart disease, according to a new study.
Optically active defects improve carbon nanotubes
- ScienceDaily
- 21/4/9 18:37
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural 'imperfections'. The challenge, however, is to control the number and type of these defects. Chemists and materials scientists have now demonstrated a new reaction pathway that enables such control for carbon nanotubes. It results in specific optically active sp3...
New biosealant can stabilize cartilage, promote healing after injury

Researchers showed that a new hyaluronic acid hydrogel system can reinforce and seal areas of injured cartilage in animal studies, paving the way for future fixes and healing.
Abrupt ice age climate changes behaved like cascading dominoes
- ScienceDaily
- 21/4/9 16:45
Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the climate system changed, other parts of the climate system followed like a series of dominos toppling in succession. Today, sea-ice extent is being rapidly reduced, and it is...
Discovery could help lengthen lifespan of electronic devices

Researchers have made a significant discovery in the field of materials science, for the first time providing a full picture of how fatigue in ferroelectric materials occurs.
Masculine traits linked to better parenting for some dads
- ScienceDaily
- 21/4/9 16:45
In some men, having traditional masculine characteristics such as competitiveness and adventurousness was linked to being better fathers to infants, a new study found. But the men in this study - highly educated and from dual-earner couples - combined those stereotypically masculine traits with the belief that they should be nurturing, highly involved fathers.
Preseismic atmospheric radon anomaly associated with 2018 northern Osaka earthquake
- ScienceDaily
- 21/4/9 16:44
The concentration of the radioactive element radon is known to change in the ground before and after earthquakes. Previous studies have shown elevated radon levels in the atmosphere before the mainshock of a large inland earthquake due to foreshock activity and slow slip.
Metabolic changes in fat tissue in obesity associated with adverse health effects
- ScienceDaily
- 21/4/9 16:44
A twin study indicates that the machinery responsible for energy handling in fat tissue is working poorly in obesity. In the study, a clear reduction was seen in the activity of mitochondrial genes in obesity in fat tissue, while similar genome-level change in muscle mitochondria was minor. A link with adverse health effects was identified in the mitochondria of fat tissue only.
Interleukin-33 involved in immunity to Sars-CoV-2
- ScienceDaily
- 21/4/9 16:44
A new study reveals the involvement of interleukin-33, an important alarm signal, when immune cells get exposed to Sars-CoV-2 for a second time.
Amounts of organic molecules in planetary systems differ from early on
- ScienceDaily
- 21/4/9 16:44
An international group of scientists have studied the chemical composition of 50 protoplanetary-disk forming regions in the Perseus Molecular Cloud, and found that despite being in the same cloud, the amounts of complex organic molecules they contain are quite different.

Researchers succeed in producing rapid, cost-effective and environmentally friendly material.
A sulfosugar from green vegetables promotes the growth of important gut bacteria
- ScienceDaily
- 21/4/9 16:44
A team of scientists has analyzed how microbes in the gut process the plant-based, sulfur-containing sugar sulfoquinovose. Their study discovered that specialized bacteria cooperate in the utilization of the sulfosugar, producing hydrogen sulfide. This gas has disparate effects on human health: at low concentrations, it has an anti-inflammatory effect, while increased amounts of hydrogen sulfide...

Researchers have discovered that bird blood produces more heat in winter, when it is colder, than in autumn.
Pillar of support: Breakthrough discovery could speed up bone implant recovery
- ScienceDaily
- 21/4/9 15:36
A research team has uncovered a new technique that can speed up recovery from bone replacements. Novel micropillars, 10 times smaller than the width of a human hair, can change the size, shape and nucleus of individual stem cells and 'trick' them to become bone. Further research will look to improve the process of locking bone replacements with reduced risk of infection.
Toward a reliable oral treatment for sickle cell disease
- ScienceDaily
- 21/4/9 15:36
For those who have sickle cell disease, there are only a few treatment options, which include bone marrow transplants, gene therapy or other treatments that address a subset of symptoms. Now, researchers report discovery of a small molecule that could treat sickle cell disease by boosting levels of fetal hemoglobin, a healthy form that adults normally do not make.
Fighting dementia with play
- ScienceDaily
- 21/4/9 15:36
A dementia diagnosis turns the world upside down, not only for the person affected but also for their relatives, as brain function gradually declines. Those affected lose their ability to plan, remember things or behave appropriately. At the same time, their motor skills also deteriorate. Ultimately, dementia patients are no longer able to handle daily life alone and need comprehensive care. New...

Health benefits of breastfeeding, for mother: Lactation and visceral, pericardial fat
- ScienceDaily
- 21/4/9 15:36
As demonstrated by multiple studies, women who breastfeed have a lower risk for developing cardiovascular disease and diabetes, though the mechanisms by which these risks are reduced for lactating women are still not fully understood. Scientists recently completed a study to see if the presence of excess fat, specifically visceral and pericardial fat, could help explain this finding.

- ScienceDaily
- 21/4/9 03:29
Sunnier areas are associated with fewer deaths from COVID-19, an observational study suggests. Increased exposure to the sun's rays -- specifically UVA -- could act as a simple public health intervention if further research establishes it causes a reduction in mortality rates, experts say.
