Study highlights tension between Canada's climate and housing goals
Canada cannot simultaneously meet its targets for emission reductions and new housing unless there's a drastic change in construction practices, according to research from the University of Toronto's Faculty of Applied Science & Engineering.
Scholars review lunar crater chronology and impact flux
Scholars reviewed the existing anchor points and construction history of lunar crater chronology. Before the return of lunar samples, the stratification of the near side of the moon was based on remote sensing data from ground-based telescopes and lunar orbiters. Six manned
New theory reveals fracture mechanism in soft materials
A new theory has finally deciphered the physical mechanisms of fracture in soft materials. This discovery could soon lead to new, defect-free materials that are more resistant and durable as well as environmentally friendly. The article "Elastic instability behind brittle
3D covalent organic frameworks with zyg topology for photocatalytic synthesis of hydrogen peroxide
A research team proposed a new synthetic strategy of COFs based on a new topology that remotely separates donor (D) and acceptor (A) units in 3D lattice to produce the expected metastable photo-induced charge-separated states.
Exploring the molecular basis of how pradimicin A binds to viral N-glycan, a potential SARS-CoV-2 entry inhibitor
HIV, Ebola and most recently, COVID-19 viruses have had an enormous impact on our societies world-wide. All these viruses are "enveloped viruses," viruses that have an exterior envelope that surrounds them largely composed of their host's cells. This envelope increases the
A combination of multicore magnetic nanoparticles and chemotherapy drugs achieves greater efficacy against cancer cells
The path to a cure for cancer is not unique, as the disease is an extremely complex process. Multiple factors are involved in the process of effectively eliminating a tumor and therefore, being able to have different strategies against cancer is key in this regard.
Researchers uncover key mechanisms in chromosome structure development
Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the organization of chromosomes appears in the Proceedings of the National Academy of
Study finds early-onset El Niño means warmer winters in East Asia, and vice versa
The phenomenon known as El Niño can cause abnormal and extreme climate around the world due to it dramatically altering the normal flow of the atmosphere. In Japan, historical data has shown that El Niño years tend to lead to warmer winters. This case was exemplified recently
Energy landscape theory sheds light on evolution of foldable proteins
A new study led by Rice University's Peter Wolynes offers new insights into the evolution of foldable proteins. The research was published in the Proceedings of the National Academy of Sciences.
Intervarietal grafts of sweet, serrano peppers on Pasilla 18M
Chili pepper (Capsicum annuum L.) is one of the most important vegetables in the world; it is the most widely cultivated and popular spice. The genus Capsicum has been distinguished by its lack of compatible rootstocks with commercial cultivars to successfully protect against
Yes, some animals can have babies without a mate. Here's how
A boa constrictor in the U.K. gave birth to 14 babies—without a mate.
Experimental bermudagrasses show varied drought response
In a new study, researchers at Oklahoma State University have unveiled significant variations in drought response among advanced turf-type Bermudagrass experimental genotypes. The study aimed to evaluate the drought tolerance of various Bermudagrass genotypes under controlled
Eco-friendly solution for battery waste: New study unveils novel metal extraction technique
A new study led by researchers in Canada introduces a novel process for the extraction and separation of metals from spent alkaline batteries, offering a promising solution for efficient recycling of critical materials.
High-resolution land surface dataset provides Earth system modeling details
Earth system models (ESMs) help us understand climate and environmental changes. With advances in computing power, ESMs can now be run at kilometer-scale (k-scale) resolutions, capturing very fine details to better predict extreme weather and understand water, carbon, and
Study reveals birth month impact on soccer careers
What do soccer players Jamal Musiala, Arda Guler and Cristiano Ronaldo have in common? Not only are they shining for their respective nations in Germany; they were each born in February. Researchers at the University of Strathclyde have found that this is not a coincidence.
Mass tourism brings dollars but with all the baggage
Last August, the picturesque Himalayan kingdom of Bhutan halved to US$100 per night a charge levied on international tourists. The fee recognized the "important role of the tourism sector in generating employment, earning foreign exchange and boosting overall economic growth."
Research investigates employment match quality
The quality of an employment match is an important aspect of understanding labor market dynamics, according to Professor Michèle Belot, but measuring match quality presents many challenges.
Scientists debate Gulf Stream's role in North Atlantic currents
A new study questions the coherence of the circulation in the North Atlantic Ocean, as researchers show that the Gulf Stream exists, but variations off the coast of Florida do not necessarily reach Norway.
New research finds Dublin is second most expensive European city in which to build apartments
Dublin is the second most expensive place to build apartments, after Zurich, according to a new construction cost report covering 10 cities across Europe published today by Trinity College Dublin and the Society of Chartered Surveyors Ireland.
How studying bat viruses can help prevent zoonotic disease
Bats have become the poster child of emerging zoonotic disease. The creatures harbor a vast array of viruses—some of which cause deadly diseases in humans—yet they rarely get sick themselves.
Study reveals worrying levels of fiberglass in oysters and mussels
A new study has revealed worrying levels of fiberglass in oysters and mussels. This marks the first time fiberglass or glass reinforced plastic (GRP) particles have been found entering the food chain and raises urgent environmental and health concerns.
New NASA Heat Map Shows Scorching Streets That Can Burn Skin in Seconds
Under the scorching summer sun, pavement can reach temperatures hot enough to cause second-degree burns
More carbon in soil can control weeds, in some cases
Cornell researchers have tested an ecological tool in the fight to control weeds in silage soybean and corn fields: adding carbon to soil in the form of sawdust and rye hay.
Image: Orion spacecraft prepares for upcoming launch
Technicians lift NASA's Orion spacecraft out of the Final Assembly and System Testing cell on June 28, 2024. The integrated spacecraft, which will be used for the Artemis II mission to orbit the moon, has been undergoing final rounds of testing and assembly, including
Out in the cold: Enhancing frost tolerance in wheat
Rugging up against winter chills is a cozy and easy option for most of us. But our crops are facing frosts and freezing temperatures without the warmth of winter woolies. Frost poses a significant threat to agriculture, particularly in Australia's wheatbelt regions.
