Canada to slap tariffs on EVs, steel from China
Canada, an export-driven economy that relies heavily on trade with the U.S., has been closely watching moves by the Biden administration to erect a much higher tariff wall against Chinese EVs, batteries, solar cells, steel and other products......»»
Adversaries love bots, short-lived IP addresses, out-of-band domains
Fastly found 91% of cyberattacks – up from 69% in 2023 – targeted multiple customers using mass scanning techniques to uncover and exploit software vulnerabilities, revealing an alarming trend in attacks spreading across a broader target base. In.....»»
3 Hulu movies you need to stream this weekend (August 23-25)
Between a character-driven drama, a survival thriller, and a spy flick, the three Hulu moves that you need to stream this weekend have everything you need......»»
World"s first micromachine twists 2D materials at will
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbe.....»»
Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds
Evolution has enabled plants to survive under adverse conditions. The winter bud of a plant is a crucial structure that establishes adaptability. Depending on environmental and intrinsic conditions, buds can transition between growth and dormancy. Th.....»»
From embers to crisis: The expanding threat of wildfires under global warming
Globally, wildfires are on the rise, driven by climate change, which exacerbates droughts and high temperatures. These fires contribute significantly to carbon emissions and particulate matter (PM2.5), with severe consequences for both climate stabil.....»»
Researchers observe Floquet states in colloidal nanoplatelets driven by visible pulses
Solution-processed semiconductor nanocrystals are also called colloidal quantum dots (QDs). While the concept of size-dependent quantum effects had long been known to physicists, a sculpture of the theory into real nanodimensional objects remained im.....»»
Novel ratchet mechanism uses a geometrically symmetric gear driven by asymmetric surface wettability
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typicall.....»»
Green light for accurate vegetation research: Evaluation of global SIF datasets
A recent study has pinpointed the top-performing solar-induced chlorophyll fluorescence (SIF) products for precise global monitoring of photosynthesis and vegetation dynamics. By thoroughly evaluating eight widely-used SIF datasets, the research team.....»»
Researchers develop nanoparticle array implantation for sensitive and reusable detection
Shanghai Jiao Tong University (SJTU) researchers have developed a highly sensitive and reusable surface-enhanced Raman spectroscopy (SERS) microfluidics system that has achieved a detection limit lower than 10 ppt (parts per trillion) of harmful subs.....»»
Project Helianthus—a solar-sail-driven geomagnetic storm tracker
Solar storms captured the imagination of much of the American public earlier this year when auroras were visible well south of their typical northern areas. As the sun ramps into another solar cycle, those storms will become more and more common, and.....»»

A new study has discovered ways to reduce the toxicity of graphene oxide (GO), an ultra-thin sheet of nanomaterial derived from graphite, laying the groundwork to use it as a drug delivery system......»»
"Killer robots" are becoming a real threat in Africa
The use of drones in the Sahel, a region of Africa that has been plagued by violence driven by jihadist insurgency for much of the past decade, has become a real problem. In April, for example, Al Qaeda's affiliate in the Sahel, Jama'at Nusrat al Isl.....»»
AI-driven method enhances electron microscopy imaging capabilities of complex biological systems
Electron microscopy has enabled visualization of the intricate details inside cells. The advancement to 3D electron microscopy, known as volume EM (vEM), has further expanded this three-dimensional, nanoscale imaging capacity. However, trade-offs bet.....»»
Novel anemometer tracks sound travel for speedier, more precise wind speed calculations on Mars
Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, cany.....»»
