Imperial researchers show that carbon taxes alone cannot reduce emissions enough to reach the Paris Agreement targets.
The Paris Agreement, signed in 2015, requires nations to collectively limit global warming to 2°C by 2100, and to pursue efforts to limit the temperature increase even further to 1.5°C.
This goal requires human-caused carbon dioxide (CO2) emissions to reach zero by 2070 and become negative afterwards, using strategies that remove CO2 from the air, such as carbon capture technologies or planting trees.
Scientists from Tomsk Polytechnic University have updated the alloying process, i.e. improving the properties of metal with impurities, which not only enhances the wear resistance of materials but also provides new qualities required by hi-tech manufacturing, science, and energy.
The study results were published in the journal Surface and Coatings Technology and presented at the conference on Surface Modification of Materials by Ion Beams (SMMIB) 2019 that recently took place in Tomsk.
Although Hurricane Juliette is no longer a major hurricane in the Eastern Pacific Ocean, NASA's Aqua satellite revealed there are still powerful thunderstorms around its center and captured an image of the storm over Socorro Island, Mexico.
Aqua provided forecasters at the National Hurricane Center with infrared data and cloud top temperature information that indicate Juliette's rainmaking capabilities that affected Socorro Island.
PHILADELPHIA -- The biggest risks for cardiovascular disease are smoking and poor diet. However, different people are more susceptible to heart disease based on very slight differences in their genes, called variants. While there have been many studies that have linked variants to cardiovascular traits, it's unclear whether these variants have functional consequences, like altered gene or protein expression.
BEER-SHEVA, Israel...September 4, 2019 - Single-sex prawns could help alleviate poverty, reduce disease and protect the environment, according to researchers at Ben-Gurion University of the Negev (BGU) who have developed a monosex prawn that may make this winning trifecta possible.
It is estimated that over 2 million Americans with dementia experience delusions (false beliefs) and hallucinations (seeing or hearing things that others do not see or hear). This group of symptoms, known as dementia-related psychosis, may cause significant distress to individuals and their families. Although common, the condition frequently goes undetected in people who may be struggling with other complex behavioral and psychological symptoms of dementia.
Hurricane Dorian dropped excessive rainfall on the Bahamas and NASA calculated the rainfall the storm generated.
"By Wednesday morning, September 4, the rain accumulation from Hurricane Dorian exceeded 36 inches in an area that included parts of Grand Bahama Island and Abaco Island," said Owen Kelley, researcher at NASA Goddard. "By that time, the Dorian's center was north of the Bahamas and was moving further north, approximately parallel to Florida's east coast."

Arthropod-transmitted viruses, known as arboviruses, can cause pandemic diseases in humans, animals, and crops. The Zika virus and cassava geminivirus are two such arboviruses. These pathogens often alter host characteristics to directly or indirectly influence arthropod vector behaviors or host-herbivore interactions, thus facilitating disease transmission.
Pathogen-infected hosts may promote the performance of vector insects; but whether and how pathogens affect nonvector insects have been largely unexplored.
Most people over age 50 say they're ready for natural disasters and emergency situations, but a new national poll shows that many haven't taken key steps to protect their health and well-being in case of severe weather, long-term power outages or other situations.
Less than half have signed up for emergency warning systems offered by their community, which can give crucial information in case of storms, natural disasters, lockdowns, evacuation orders, public health emergencies and more.
CHAPEL HILL, N.C. - SEPTEMBER 4, 2019 - People allergic to peanuts may have a new way to protect themselves from severe allergic reactions to accidental peanut exposure. It's called sublingual immunotherapy - or SLIT - and it involves putting a miniscule amount of liquefied peanut protein under the tongue, where it is absorbed immediately into the blood stream to desensitize the immune system to larger amounts of peanut protein.
DNA is a long chemical sequence that carries genetic information. Inspired by this biological system, in recent years many research teams have been exploring how to store and then decode information within synthetic macromolecules, also called polymers*.
Tip-enhanced Raman spectroscopy resolved "resonance" Raman scattering with 1-nm resolution in ultrathin zinc oxide films epitaxially grown on a single-crystal silver surface. Tip-enhanced "resonance" Raman scattering can be used to investigate a specific chemical structure at nanoscale and at the single-molecule level and provides a new approach for the atomic-scale optical characterization of local electronic states. This will be a powerful tool to study, local defects in low-dimensional materials and active sites of heterogeneous catalysis.
SEATTLE -- September 4, 2019 -- A team led by researchers at Fred Hutchinson Cancer Research Center has identified several women's health benefits from a low-fat diet. The findings, published in the September issue of the Journal of Nutrition, found a low-fat diet commensurate with an increase in fruit, vegetable and grain servings reduced death following breast cancer, slowed diabetes progression and prevented coronary heart disease.
A team of researchers from Osaka University, the Institute for High Pressure Physics and the Institute for Nuclear Research of Russian Academy of Sciences (Russia), and TU Dresden (Germany), discovered an effective method for removing lattice defects from crystals. Their research results were published in Journal of Physics: Materials.
Superconductivity enables us to prevent loss when transporting energy from power plants to our homes. However, to do this, the lines must be cooled to temperatures that are so low as to make large-scale use of superconductors uneconomic at present. Therefore, in laboratories across the world researchers are looking for new superconductive materials that function at less prohibitive temperatures.
