Bumblebees" nutrition influences their pesticide resistance
How susceptible bumblebees are to a common fungicide depends on the flowering plants to which it is applied on and how diverse the food supply is that is available to the insects. Monocultures can increase the insects' sensitivity to the fungicide or.....»»
Almost ready for prime time: Deep UV photodetectors head to real-world testing
Numerous devices and detectors sense and catalog deep ultraviolet frequencies that the Earth's ozone layer otherwise absorbs. Most solar-blind space-borne imaging platforms still rely on photomultiplier tubes and/or microchannel plates working with s.....»»
SARS-CoV-2: Neutralization of BA.1 and BA.2 by therapeutic monoclonal antibodies
Scientists studied the sensitivity of Omicron BA.1 and BA.2 to nine monoclonal antibodies, some of which are used in pre-exposure prophylaxis in immunocompromised individuals. The scientists showed a loss of neutralizing activity against BA.1 and BA......»»
A New Tool for Finding Dark Matter Digs Up Nothing
Physicists are devising clever ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But they’ve seen no signs of exotica yet......»»
Growth-climate sensitivity of two pine species varies with site-specific environmental conditions
A better understanding of tree growth-climate sensitivity across regions and species may reduce uncertainties in simulating forest carbon budgets. However, few studies have explored the growth-climate sensitivity of different tree species in Southwes.....»»
Researchers observe total reflection of ultraviolet wave train at a coronal hole
Researchers from Yunnan Observatories of the Chinese Academy of Sciences observed and verified for the first time that the coronal wave train totally reflected at the coronal hole boundary, which provides essential evidence for the essence of the cor.....»»
Team at Borexino shows it is possible to have directional and energy sensitivity when studying solar neutrinos
A group of researchers working with data from the Borexino detector at the Laboratori Nazionali del Gran Sasso in Italy, has shown that it is possible to measure solar neutrinos with both directional and energy sensitivity. Two teams within the group.....»»
European probe captures the highest resolution image of the Sun"s corona ever taken
A series of images were captured on March 7. The crown jewel of the set was photographed using the Extreme Ultraviolet Imager (EUI) at a distance of roughly 46.6 million miles from the Sun, or about halfway between the Earth and the Sun......»»
