Despite being championed by a host of celebrity chefs, crayfish 'trapping' is not helping to control invasive American signal crayfish, according to new research by UCL and King's College London.
There have been grave concerns within the science community and amongst conservationists that American signal crayfish are wiping out other species of crayfish across Europe - including Britain's only native crayfish, the endangered white-clawed crayfish.
Tsukuba, Japan -- Life is an exquisite orchestration of growth and change, with checks and balances that fine-tune complex entwined interactions, both intrinsic and external. White blood cells (WBC) are integral to an organism's immune defenses against disease and invasion; unfortunately, these mechanisms may go awry causing uncontrolled increases in dysfunctional cell numbers, resulting in tumor formation.
p>Through a simple process of heating and cooling, New York University researchers have created a new crystal form of deltamethrin--a common insecticide used to control malaria--resulting in an insecticide that is up to 12 times more effective against mosquitoes than the existing form.
The findings, published in the journal Proceedings of the National Academy of Sciences (PNAS), may provide a much-needed and affordable insecticide alternative in the face of growing resistance among mosquitoes.
Researchers at Linköping University, Sweden, have discovered a new mechanism by which substances can open a certain type of ion channel and in this way regulate nerve impulses. The study, published in the scientific journal PNAS, identifies a large group of substances that influence the coupling between the various functional parts of an ion channel. The discovery may help in the development of future drugs.
Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene--a one-atom-thick sheet of carbon arranged in a hexagonal lattice--the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity.
Now, a team of researchers at Columbia University and the University of Washington has discovered that a variety of exotic electronic states, including a rare form of magnetism, can arise in a three-layer graphene structure.
Geoscientists at the University of Sydney have discovered a natural laboratory to test claims that the carbon captured during the erosion and weathering of common rocks could be a viable mitigation strategy against global warming.
That laboratory is the Tweed River valley in north-eastern New South Wales.
When an optical fiber is immersed in liquid, a high temperature, high speed jet is discharged. Researchers expect this to be applied to medical treatment in the future. Now, a research team from Russia and Japan has explored this phenomenon further and revealed the reasons behind the jet formation.
Scientists have estimated that the age of an individual does not indicate how likely they are to be infected by SARS-CoV-2. However, development of symptoms, progression of the disease, and mortality are age-dependent.
There have been a large number of deaths due to the ongoing COVID-19 pandemic, and it has been shown that elderly individuals disproportionately develop severe symptoms and show higher mortality.
BioIVT, a leading provider of research models and services for drug and diagnostic development, today announced the publication of research describing the use of HEPATOPAC® cultures with a targeted in vitro assay to identify small molecule drugs with high potential for drug-induced liver injury (DILI).1
While on COVID lockdown, a University of Sydney honours student has written a research paper on a star system dubbed one of the "exotic peacocks of the stellar world".
Only one in a hundred million stars makes the cut to be classified a Wolf-Rayet: ferociously bright, hot stars doomed to imminent collapse in a supernova explosion leaving only a dark remnant, such as a black hole.
Cheaper refrigerators? Stronger hip implants? A better understanding of human disease? All of these could be possible and more, someday, thanks to an ambitious new project underway at the National Institute of Standards and Technology (NIST).
Virologists at the KU Leuven Rega Institute have been working on two lines of SARS-CoV-2 research: searching for a vaccine to prevent infection, and testing existing drugs to see which one can reduce the amount of virus in infected people.
Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena. Targeting this enzyme may help control plant parasitism in crops. Also, this mechanism can be exploited for novel cross-species grafting techniques to realize the goal of sustainable agricultural technologies.
Optical nanoantennas can convert propagating light to local fields. The local-field responses can be engineered to exhibit nontrivial features in spatial, spectral and temporal domains. Local-field interferences play a key role in the engineering of the local-field responses. By controlling the local-field interferences, researchers have demonstrated local-field responses with various spatial distributions, spectral dispersions and temporal dynamics.
A team of scientists at Utah State University has developed a new tool to forecast drought and water flow in the Colorado River several years in advance. Although the river's headwaters are in landlocked Wyoming and Colorado, water levels are linked to sea surface temperatures in parts of the Pacific and Atlantic oceans and the water's long-term ocean memory. The group's paper, "Colorado River water supply is predictable on multi-year timescales owning to long-term ocean memory" was published October 9 by Communications Earth and Environment, an open-access journal from Nature Research.
