Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
The National Science Foundation (NSF) has selected Dr. Anne Kinney to serve as head of the Directorate for Mathematical and Physical Sciences (MPS), which supports fundamental research in astronomy, c...
A new study describes how head-on collisions between protein machines on chromosomes can disrupt DNA replication and boost the rate of gene mutations that help bacteria survive hostile environments, r...
The National Science Foundation (NSF) has selected William E. Easterling to serve as head of the Directorate for Geosciences (GEO), which supports fundamental research spanning the atmospheric, earth,...
For the first time scientists have looked at the net balance of the three major greenhouse gases—carbon dioxide, methane, and nitrous oxide—for every region of Earth’s landmasses. They found surprisin...
This is the 11th part in a series on NSF's geosciences risk and resilience interest area. Please see parts one, two, three,four, five, six, seven, eight, nine...
Human head and body lice are obligatory hematophagous ectoparasites that belong to a single species Pediculus humanus. Only body lice, however, are vectors of the infections gram-negative bacteria Bar...
The National Science Foundation (NSF) has selected George Mason University's James L. Olds to serve as assistant director for the Directorate for Biological Sciences (BIO). BIO's mission is to enable ...
In a recent paper "Head-on collision of electron acoustic solitary waves in a plasma with nonextensive hot electrons" [Astrophys. Space Sci. 338, 271-278 (2012)] Eslami, Mottaghizadeh and Pakzad deal ...
Fusarium head blight (FHB) is one of the most serious diseases of wheat (Triticum aestivum L.). FHB  reduces grain yield and quality, and the fungus produces mycotoxins, such as deoxynivalenol (D...
The effect of selection for two donor-QTL from Fusarium head blight (FHB) resistant spring wheat variety Sumai 3 on the reduction of deoxynivalenol (DON) content and FHB index was evaluated in field t...
Fusarium head blight (FHB) is a fungal disease causing substantial yield and quality losses in barley. Genetic variation in deoxynivalenol (DON) contentand and important yield traits in response to FH...
The response of four winter wheat cultivars, differing in resistance to Fusarium head blight (FHB), to spray inoculation with four selected Fusarium graminearum isolates, mixture of these isolates and...
We present a novel fiber-based near-field optical head consisting of a straw-shaped writing probe and a flat gap sensing probe. The strawshaped probe with a C-aperture on the end face exhibits enhance...
Abstract: We evaluate particle production in highly asymmetric head-on collisions of lasers pulses due to non-perturbative coherent action of many photons. We obtain the yield of electron-positron pai...
