Don't be alarmed when the sky goes dark on April 8. A total solar eclipse will traverse North America, crossing Mexico, the United States, and Canada. This event will mark the only total solar eclipse visible from the United States until 2044. The full path of totality, as it's called, will begin on Mexico's Pacific Coast, cross northwestern Pennsylvania and New York state, and exit at the Atlantic Coast of Newfoundland, Canada.

More than three-quarters of trans people in Maryland worried about being negatively judged when seeking health care and nearly a third delayed necessary treatment, according to one finding of a new study of the state's trans population conducted in part by a University of Maryland doctoral student.

The next solar eclipse will be visible across North America on April 8. Solar eclipses occur when the moon passes between the sun and the Earth, blocking sunlight and casting a shadow on our planet. There will be a 115-mile-wide path stretching from Maine to Texas with a total solar eclipse, while the rest of the continental United States will have a partial eclipse.

Prof. Huang Qunying's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. Ning Shunyan's team from South China University, developed a novel silica-based adsorbent for the highly selective separation of strontium (Sr) from an acidic medium.

Adults who struggle to read often read at a slower pace and with lower accuracy compared to their peers. They can also have difficulties with spoken language skills, such as difficulties with understanding and using words, and recognizing and working with sounds associated with spoken language.

In the realm of science and technology, harnessing coherent light sources in the deep ultraviolet (DUV) region holds immense significance across various applications such as lithography, defect inspection, metrology, and spectroscopy. Traditionally, high-power 193-nanometer (nm) lasers have been pivotal in lithography, forming an integral part of systems used for precise patterning. However, the coherence limitations associated with conventional ArF excimer lasers hinder their effectiveness in applications requiring high-resolution patterns... Читать дальше...

The popular social media app TikTok is facing an uncertain future in the U.S. amid concerns about national security. In Congress, the House passed a bill recently that would lead to a nationwide ban of the platform if its China-based owner, ByteDance, doesn't sell off its stake.

Ceramic pots endure the corrosive effects of thousands of years, and organic remains preserved inside the pores can shed light on the culture, values, diets, and daily life of societies. This research is achieved with the help of biomarkers.

As the world eagerly anticipates the upcoming total solar eclipse on April 8, 2024, NASA is preparing for an extraordinary opportunity for scientific discovery, open collaboration, and public engagement. At the heart of the agency's approach to this unusual event lies a commitment to open science, ensuring that the data captured during the eclipse is readily accessible to all.

A broader past could mean a brighter future for Canada lynx in the U.S., according to recent research. The study, published in the journal Biological Conservation, indicates that lynx might do well in the future in parts of Utah, central Idaho and the Yellowstone National Park region, even considering climate change and the lack of lynx in those areas now.

The New York State Department of Corrections and Community Supervision is canceling visits to nearly two dozen facilities expected to be thrown into "total darkness" amid the solar eclipse on April 8.

On a recent weekday, short but mighty flames began consuming an expanse of tallgrass in Illinois' Nachusa Grasslands, their advance marked with crackles and pops.

In a study published in Global Change Biology, scientists from the Institute of Earth Environment and the South China Botanical Garden of the Chinese Academy of Sciences have shed light on understanding the effects of nitrogen addition on soil organic carbon storage across soil profiles. Their findings may help address the recent controversial issues of managing soil as a carbon sink under elevated nitrogen deposition.

The capacity to accurately monitor the timing of vegetation growth phases, known as land surface phenology (LSP), at fine spatial scales is critical for understanding ecosystem functions and managing natural resources. Despite advancements, the sparsity of high-resolution satellite data caused by cloud cover and limited revisit times complicates this task.

Gross Primary Production (GPP), the process through which plants convert carbon dioxide and sunlight into glucose and oxygen, is the Earth's largest carbon flux. Accurate quantification of GPP is crucial for understanding carbon budgets and their implications on climate change and land management policies. However, traditional methods for estimating global GPP are challenged by the complexity of integrating biophysical and biochemical processes at various scales.

A vast burn scar unfolds in drone footage of a landscape seared by massive wildfires north of Lake Tahoe. But amid the expanses of torched trees and gray soil, an unburnt island of lush green emerges.

Studying exoplanets is made more difficult by the light from the host star. Coronagraphs are devices that block out the star light and both JWST and Nancy Grace Roman Telescope are equipped with them. Current coronagraphs are not quite capable of seeing other Earths but work is underway to push the limits of technology and even science for a new, more advanced device. A paper published on the arXiv pre-print server explores the quantum techniques that may one day allow us to make such observations.

Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers at the National Institute of Standards and Technology (NIST) has developed a technique that uses an ordinary cellphone magnetometer for an entirely different purpose—to measure the concentration of glucose, a marker for diabetes, to high accuracy.

South Africa's Cape south coast offers many hints about how our human ancestors lived some 35,000 to 400,000 years ago during the Pleistocene epoch. These clues are captured in the dunes they once traversed, today cemented and preserved in a rock type known as aeolianite.

The unique regulatory environment for the clearance and use of antimicrobial susceptibility test (AST) systems is complex in the U.S. While members of the medical microbiology community recognize the importance of updating breakpoints for clinical and public health, there is a knowledge gap regarding the regulatory requirements for breakpoint updates and how these requirements impact the medical laboratory's update processes.

Interstate 90 fractures the spine of the Cascades at its midpoint.

On April 8, North America will experience a total solar eclipse, stretching across parts of Mexico, the U.S. and Canada, with approximately 31.6 million people living in the path of totality. According to NASA, every contiguous state in the U.S., along with parts of Alaska and Hawaii, will witness at least a partial solar eclipse.

A new report released on March 28 highlights the opportunity for New England to dramatically expand forest protections and sustainably meet the region's wood product needs by reducing consumption and reorienting production.

Leaders are often encouraged to be open, authentic and vulnerable at work. Employees are similarly told their voices matter in the workplace and to speak up when they need to. But, being open and honest at work is not always as straightforward as these messages suggest.
