- ScienceDaily
- 20/9/4 18:51
Multisystem inflammatory syndrome in children (MIS-C) appears even after asymptomatic cases of COVID-19, a case review confirms, and in some children damages the heart to the extent that the children will need long-term monitoring and interventions.
Unexpected electrical current that could stabilize fusion reactions
- ScienceDaily
- 20/9/4 18:51
Scientists have found that electrical currents can form in ways not known before. The novel findings could give researchers greater ability to bring the fusion energy that drives the sun and stars to Earth.
Autophagy: the beginning of the end
- ScienceDaily
- 20/9/4 18:13
Autophagy, from the Greek for 'self-eating', is an essential process that isolates and recycles cellular components under conditions of stress or when resources are limited. Scientists have now reconstructed the first steps in the formation of autophagosomes. They show that tiny vesicles loaded with the protein Atg9 act as the seed from which the autophagosome emerges.
New technology lets quantum bits hold information for 10,000 times longer than previous record
- ScienceDaily
- 20/9/4 18:13
Quantum bits, or qubits, can hold quantum information much longer now thanks to efforts by an international research team. The researchers have increased the retention time, or coherence time, to 10 milliseconds - 10,000 times longer than the previous record - by combining the orbital motion and spinning inside an atom. Such a boost in information retention has major implications for information...
Plant protein discovery could reduce need for fertilizer
- ScienceDaily
- 20/9/4 18:13
Researchers have discovered how a protein in plant roots controls the uptake of minerals and water, a finding which could improve the tolerance of agricultural crops to climate change and reduce the need for chemical fertilizers.
Unconventional T cells in severe COVID-19 patients could predict disease outcome
- ScienceDaily
- 20/9/4 18:13
Researchers in France have discovered that patients suffering from severe COVID-19 show changes in a class of immune cells known as unconventional T cells. The study suggests that monitoring the activity of these cells in the blood of patients could predict the severity and course of the disease.
Blood breakdown product commandeers important enzyme
- ScienceDaily
- 20/9/4 18:13
The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, 'heme' is produced, which in turn can influence the protein cocktail in the blood. Researchers have now discovered in complex detective work that the 'activated protein C' (APC) can be commandeered by heme. At the same time, APC can also reduce the toxic effect of...
Pollination: Air pollution renders flower odors unattractive to moths
- ScienceDaily
- 20/9/4 16:18
Researchers showed that tobacco hawkmoths lost attraction to the scent of their preferred flowers when that scent had been altered by ozone. This oxidizing pollutant thus disturbs the chemical communication between a plant and its pollinator. However, when given the chance, hawkmoths quickly learn that an unpleasantly polluted scent may lead to nutritious nectar.
The potential of green infrastructure in mitigating flood impacts: Focused on the mobility of low income and minority comunities
- ScienceDaily
- 20/9/4 16:06
This research advances national U.S. methods for assessing flood vulnerability and prioritizing transportation improvement investments, to ensure that no community is left stranded when the next flood occurs.
Nanoearthquakes control spin centers in SiC
- ScienceDaily
- 20/9/4 16:06
Researchers have demonstrated the use of elastic vibrations to manipulate the spin states of optically active color centers in SiC at room temperature. They show a non-trivial dependence of the acoustically induced spin transitions on the spin quantization direction, which can lead to chiral spin-acoustic resonances. These findings are important for applications in future quantum-electronic...
Does the COVID-19 cytokine storm exist?
- ScienceDaily
- 20/9/4 16:05
Cytokines play a crucial role in the immune response. If this immune response is too strong, also known as 'cytokine storm', it can cause harm to the patient. Following the measurement of several important cytokines in patients with COVID-19 and various other severe diseases, researchers show that COVID-19 is not characterized by a cytokine storm. This may have consequences for the treatment of...
