Study links abnormally high blood sugar with higher risk of death in COVID-19 patients not previously diagnosed with diabetes

Saturday July 11th, 2020 01:22:47 AM
New research from Wuhan, China shows that, in patients with COVID-19 but without a previous diagnosis of diabetes, abnormally high blood sugar is associated with more than double the risk of death and also an increased risk of severe complications.

Couldn't socially distance? Blame your working memory

Saturday July 11th, 2020 01:22:41 AM
A new study highlights the critical role that working memory capacity plays in social distancing compliance during the early stages of the COVID-19 pandemic.

Physicians give first comprehensive review of COVID-19's effects outside the lung

Saturday July 11th, 2020 01:22:40 AM
Based on their experience treating COVID-19, physicians have assembled critical information about the coronavirus's effects on organs outside the lungs.

Like humans, beluga whales form social networks beyond family ties

Saturday July 11th, 2020 01:22:33 AM
A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how animal cultures emerge.

Extraordinary regeneration of neurons in zebrafish

Friday July 10th, 2020 06:07:24 PM
Biologists have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish. They studies the Mauthner cells, which are solely responsible for the escape behavior of the fish, and previously regarded as incapable of regeneration. However, their ability to regenerate crucially depends on the location of the injury.

Study pinpoints brain cells that trigger sugar cravings and consumption

Friday July 10th, 2020 06:07:22 PM
New research has identified for the first time the specific brain cells that control how much sugar you eat and how much you crave sweet tasting food. The study specifically identifies the brain cells that respond to the hormone FGF21 to regulate sugar intake and sweet taste preference.

Arctic Ocean changes driven by sub-Arctic seas

Friday July 10th, 2020 06:07:20 PM
New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.

Fast-spreading mutation helps common flu subtype escape immune response

Friday July 10th, 2020 05:15:20 PM
Strains of a common subtype of influenza virus, H3N2, have almost universally acquired a mutation that effectively blocks antibodies from binding to a key viral protein.

Invention: 'Nanocage' tool untangles (molecular) spaghetti

Friday July 10th, 2020 05:15:19 PM
Scientists have invented a new tool -- they call it a ''nanocage'' -- that can catch and straighten out molecule-sized tangles of polymers - -whether made of protein or plastic. This tool -- that works a bit like pulling a wad of thread through a needle hole -- opens a new way to create custom materials that have never been made before.

Global COVID-19 registry finds strokes associated with COVID-19 are more severe, have worse outcomes and higher mortality

Friday July 10th, 2020 05:15:16 PM
Patients with COVID-19 who have an acute ischemic stroke (AIS) experience more severe strokes, have worse functional outcomes and are more likely to die of stroke than AIS patients who do not have COVID-19. The wide range of complications associated with COVID-19 likely explain the worse outcomes.

COVID-19 can be transmitted in the womb, reports pediatric infectious disease journal

Friday July 10th, 2020 05:15:12 PM
A baby girl in Texas -- born prematurely to a mother with COVID-19 -- is the strongest evidence to date that intrauterine (in the womb) transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can occur, according to a new report.

Changes in the immune system can promote healthy aging

Friday July 10th, 2020 04:18:10 PM
As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances. Such chronic inflammation is associated with multiple age-related diseases including arthritis and Alzheimer's disease, and impaired immune responses to infection. One of the questions in ageing research is whether chronic inflammation is a cause of aging, or a consequence of the aging process itself? Scientists have found evidence suggesting that increased inflammation causes the aging process to speed up, and that there is a fine balance between maintaining immune system function and longevity.

Microscopy technique reveals nanoscale detail of coatings as they dry

Friday July 10th, 2020 04:18:05 PM
Thin film coatings do more than add color to walls. For example, they can be used as pharmaceutical devices. How these coatings dry can change their properties, which is especially important for films used in drug delivery. Engineering researchers studying the in situ drying behavior of thin film coatings are visualizing particle interactions with groundbreaking precision. Their findings could impact the development of drug delivery technology.

Understanding the love-hate relationship of halide perovskites with the sun

Friday July 10th, 2020 03:21:12 PM
Perovskiet solar cells are at the center of much recent solar research. The material is cheap and almost as efficient as silicon. However, perovskite cells have a love-hate-relationship with the sun. The light they need to generate electricity, also impairs the quality of the cells, limiting efficiency and stability over time. Research now sheds new light on the causes of this degradation.

Why lopinavir and hydroxychloroquine do not work on COVID-19

Friday July 10th, 2020 03:21:08 PM
Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. Researchers have now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.

Robust high-performance data storage through magnetic anisotropy

Friday July 10th, 2020 03:21:06 PM
A technologically relevant material for HAMR data memories are thin films of iron-platinum nanograins. An international team has now observed experimentally for the first time how a special spin-lattice interaction in these iron-platinum thin films cancels out the thermal expansion of the crystal lattice.

Construction: How to turn 36 seconds into USD 5.4 billion

Friday July 10th, 2020 02:48:44 PM
A team of researchers have, for the first time ever, linked 40 years of productivity data from the construction industry with the actual work done. The results show that productivity in the construction industry has been declining since the 1970s. The results also explain the decline and how to achieve far more efficient construction in North America and Europe.

T-ray camera speed boosted a hundred times over

Friday July 10th, 2020 02:48:39 PM
Scientists are a step closer to developing a fast and cost effective camera that utilizes terahertz radiation, potentially opening the opportunity for them to be used in non-invasive security and medical screening.

An early morning whey protein snack increases morning blood sugar level in healthy people

Friday July 10th, 2020 02:48:37 PM
Consuming protein at night increases blood sugar level in the morning for healthy people, according to new research.

Less impact from wildfire smoke on climate

Friday July 10th, 2020 02:09:44 PM
New research revealed that tiny, sunlight-absorbing particles in wildfire smoke may have less impact on climate than widely hypothesized because reactions as the plume mixes with clean air reduce its absorbing power and climate-warming effect.
