Hummingbirds use two distinct sensory strategies to control their flight, depending on whether they're hovering or in forward motion, according to new research.
A Rutgers biophysical chemist and his brother, a political scientist on the West Coast, have joined intellectual forces, realizing a long-standing dream of co-authoring an article that bridges their disciplines involving cells and society. In their paper, they have proposed that powerful parallels exist between the microscopic, natural world of cells and molecules and the human-forged realm of organizations and political systems.
Phosphorus is essential for undisturbed plant growth and development. However, in many soils, phosphorus is only poorly available. One mechanism used by plants to increase phosphorus availability is the release of malate, an organic acid, which can form complexes with iron or aluminium in the soil, thereby liberating sorbed phosphate. However, this response can also result in iron overaccumulation, which can inhibit root growth.
A new study suggests that once developed, a universal vaccine in advance of the next coronavirus epidemic/pandemic can save up to 7 million hospitalizations and 2 million deaths even when it is the only intervention being implemented and its efficacy is as low as 10 percent.
Researchers have developed a new technology that uses meta-optical devices to perform thermal imaging. The approach provides richer information about imaged objects, which could broaden the use of thermal imaging in fields such as autonomous navigation, security, thermography, medical imaging and remote sensing.
Scientists have produced an organoid model of the human conjunctiva. These organoids mimic the function of the actual human conjunctiva, a tissue involved in tear production. Using their new model, the researchers discovered a new cell type in this tissue: tuft cells. The tuft cells become more abundant under allergy-like conditions and are therefore likely to play a role in allergies. The organoid model can now be used to test drugs for several diseases affecting the conjunctiva.
Open information also will make countries better able to manage vital ocean resources effectively. But the sheer size of the ocean has made tracking industrial activities at a broad scale impractical – until now
This week’s Sci-Five quiz is on astronauts in space.
The study revealed tetrahydrocannabidiol obtained from cannabis could fight methicillin-resistant Staphylococcus aureus
Throughout their evolutionary history, most baleen whales were relatively much smaller, around five metres in length.
Traditionally, people have been forced to reduce complex choices to a small handful of options that don’t do justice to their true desires
There’s no shortage of apps and technology that claim to shift the brain into a “theta” state – said to help with relaxation, inward focus and sleep
Nicholas Copernicus, or Mikołaj Kopernik in Polish, was born in Toruń in 1473. He was the youngest of four children born to a local merchant
A new study has revealed that these two ice giants are actually very similar shades of greenish blue
Rapid-acting antidepressants, including ketamine, scopolamine and psilocybin, have been found to have immediate and lasting positive effects on mood in patients with major depressive disorder but how these effects arise is unknown. New research has explored their neuropsychological effects and found that all three of these drugs can modulate affective biases associated with learning and memory.
The widely used dry-cleaning and degreasing solvent perc can be converted to useful chemicals by a new clean, safe and inexpensive procedure. The discovery using on-demand UV activation may open the path to upcycling perc and thus contribute to a more sustainable society.
Soy compounds called isoflavones are among the plant-derived compounds that may significantly reduce the risk of breast cancer recurrence or death, according to a new meta-analysis.
Researchers uncovered a fundamental mechanism that controls the body's response to limited oxygen and regulates blood vessel disease of the lung.
By exploiting the technology used in Covid-19 vaccines, a team of scientists has created an effective therapy for a rare disease, in a study in mice, demonstrating the technology's potential therapeutic use in people.
Increases in symptoms of depression are associated with a subsequent increase in bodyweight when measured one month later, new research has found. The study found that the increase was greatest among people with overweight or obesity, but found no link between generally having greater symptoms of depression and higher bodyweight.
