Invasive, native marsh grasses may provide similar benefits to protected wetlands

An invasive species of marsh grass that spreads, kudzu-like, throughout North American wetlands, may provide similar benefits to protected wetlands as native marsh grasses. According to new research, the invasive marsh grass’s effects on carbon storage, erosion prevention and plant diversity in protected wetlands are neutral.

Earth probably began with a solid shell

Plate tectonics — a defining feature of modern Earth and the driving force behind earthquakes, volcanoes and mid-ocean spreading ridges — did not start until later in Earth’s history, new research suggests. The work is the latest salvo in a long-standing geological debate: did plate tectonics start right away, or did Earth begin with a solid shell covering the entire planet? The new results suggest the latter.

Triboelectric nanogenerators boost mass spectrometry performance

Triboelectric nanogenerators (TENG) convert mechanical energy harvested from the environment to electricity for powering small devices such as sensors or for recharging consumer electronics. Now, researchers have harnessed these devices to improve the charging of molecules in a way that dramatically boosts the sensitivity of a widely-used chemical analysis technique.

New species of parasitic wasp discovered in the eggs of leaf-rolling weevils in Africa

A new species of parasitic wasp has been obtained from the eggs of weevils associated with bushwillows in northeastern Gabon. Given the tiny insect is the first record of its genus for West-Central Africa, the researchers decided to assign the wasp a name to celebrate its origin. …

New insights into the mechanisms into how ungulates got bigger in the Neogene

The observed increase of body size in ungulates during the 20 million years before the Pleistocene is driven by the process of species selection, according to researchers. Bigger ungulate species became more common because of a higher origination and lower extinction rate. The study is the first to compare the evolution of two mammalian clades during the Neogene on two continents. The researchers point out that this biogeographic perspective yields complex explanations for apparently shared patterns. …

New mech­an­ism un­der­ly­ing epi­lepsy found

Prolonged epileptic seizures may cause serious problems that will continue for the rest of a patient’s life. As a result of a seizure, neural connections of the brain may be rewired in an incorrect way. This may result in seizures that are difficult to control with medication. Mechanisms underlying this phenomenon are not entirely known, which makes current therapies ineffective in some patients.

Changes in RNA splicing: A new mechanism for genetic risk in schizophrenia

New research has identified sections of DNA associated with altered regulation of gene expression underlying schizophrenia. The implicated loci contribute to schizophrenia risk by affecting alternative splicing, part of the process that translates the same DNA code into multiple different proteins.
