Scientists use AI to develop better predictions of why children struggle at school
Scientists using machine learning -- a type of artificial intelligence -- with data from hundreds of children who struggle at school, identified clusters of learning difficulties which did not match the previous diagnosis the children had been given. The researchers from the Medical Research Council Cognition and Brain Sciences Unit at the University of Cambridge say this reinforces the need for children to receive detailed assessments of their cognitive skills to identify the best type of support.

Unveiling the mechanism protecting replicated DNA from degradation
Researchers have succeeded in depleting AND-1, a key protein for DNA replication, by using a recently developed conditional protein degradation system. Consequently, they were able to gain unprecedented access to the mechanism behind how AND-1 works during DNA replication and cell proliferation in vertebrate cells, demonstrating that AND-1 has two different functions during DNA replication mediated by different domains of AND-1.

The Coriolis effect impacts global patterns and currents, and its magnitude, relative to the magnitude of inertial forces, is expressed by the Rossby number. For over 100 years, scientists have believed that the higher this number, the less likely Coriolis effect influences oceanic or atmospheric events. Recently, however, researchers found that smaller ocean disturbances with high Rossby numbers are influenced by the Coriolis effect. Their discovery challenges assumptions of theoretical oceanography and geophysical fluid dynamics.

These macrophages congregated specifically in atherosclerotic plaques that arose after feeding on a high-cholesterol diet. In vivo imaging detected the amount of aortic plaque formed and its change over time, which could help in assessing the efficacy of anti-atherosclerotic drugs.

Persistent weather conditions can lead to weather extremes such as drought, heat waves, prolonged cold and storms that can cost millions of dollars in damage and disrupt societies and ecosystems, the study says.

Tracking hydrogen movement using subatomic particles
Scientists have developed a technique using a beam of subatomic particles called muons to track hydrogen movement in the solid magnesium hydride for the first time. The negative muon beam provided spectra that showed the local nuclear magnetic fields of hydrogens in magnesium hydride. This technique expands our ability to investigate hydrogen transfer in solid materials, which should help to facilitate the development of hydrogen storage materials.

Researchers found the fossil in the Mancos Shale Formation in Utah, in ancient delta deposits formed during a poorly understood interval in the North American fossil record.

New findings show that a micro RNA from the shoot keeps legume roots susceptible to symbiotic infection by downregulating a gene that would otherwise hinder root responses to symbiotic bacteria. These findings help us understand what it takes to make nitrogen-fixing symbiosis efficient, and what we need to do to exploit it agronomically.

Screening using body mass index alone may miss every second preschooler with excess stomach fat
When assessing whether preschoolers are overweight, health professionals should use other measures such as waist-to-height ratio in addition to the body mass index (BMI). A study shows that this is because measuring the BMI of younger children often fails to identify those with excess stomach fat and possible associated health problems.

Neurologists have provided, for the first time, evidence that blood deposits in the brain may not require a blood vessel tear. The researchers found that brain endothelial cells, the cells that line blood vessels of the brain, have the capacity for engulfing red blood cells and depositing them outside the blood vessels and into the substance of the brain, without requiring a disruption of the vasculature.

Desert ants can quickly learn many different food odors and remember them for the rest of their lives. Their memory for nest odors seems to differ from their food odor memory: Whereas food odors are learned and kept after a single contact, ants need several trials to memorize nest odors and forget a nest-associated odor quickly after it has been removed from the nest. Hence, ants process food and nest odors differently in their brains.
