Mosquito surveillance uncovers new information about malaria transmission in Madagascar

A recent study published in PLoS Neglected Tropical Diseases reveals that female Anopheles mosquitoes bite more often and have varied diets than previously assumed. The study also found that certain species of Anopheles mosquitoes, typically considered less important for malaria transmission, are infected with the Plasmodium parasite.

NIST's compact atomic gyroscope displays new twists

The NIST team has upgraded their compact atomic gyroscope to enable simultaneous measurement of rotation, rotation angle and acceleration with a single source of atoms. The instrument's sensitivities for the magnitude and direction of the rotation measurements are approaching those achieved by other research groups using larger atom in...

How procrastinators and doers differ genetically

A study found that women tend to procrastinate due to a genetic predisposition towards high dopamine levels, which affects brain regions involved in decision-making and impulse control. This trait is not observed in men, who show no correlation between the tyrosine hydroxylase gene and action control.

Alternating currents cause Jupiter's aurora

Researchers measured Jupiter's electric current system and found that alternating currents play a crucial role in generating the aurora. The study used data from NASA's Juno spacecraft to derive electric currents and found a total of approximately 50 million amperes, significantly lower than expected values.

Mathematical model explores daily rhythms in pain sensitivity

A computational model simulates how pain is transmitted from a nerve to the spinal cord's dorsal horn, reproducing experimental results on pain sensitivity. The model suggests a potential mechanism for neuropathic pain's flipped sensitivity rhythm: a change from inhibition to excitation in synaptic connections between nerve cells.

Hubble uncovers black hole that shouldn't exist

Researchers observed a supermassive black hole in galaxy NGC 3147 with an unusual thin disk of gas swirling around it, contrary to predictions. The team used Hubble Space Telescope's STIS instrument to study the disk, revealing unique features that can only be explained by Einstein's theories of relativity.

Yield-boosting stay-green gene identified from 118-year-old experiment in corn

A corn gene identified from a 118-year-old experiment at the University of Illinois can boost yields by an average of 4.6 bushels per acre, requiring no additional fertilizer inputs. The gene, NAC7, controls senescence and stays green longer, allowing plants to continue photosynthesizing and producing grain.
