Are you a grade B maple syrup fan? For a lot of maple syrup connoisseurs, grade B was always the go-to syrup. It's dark, caramelly, rich, complex. But unfortunately, you can't get it anymore.

An enormous hole 22 meters in diameter has been dug near the summit of Cerro Chajnantor in Chile's Atacama Desert, at an elevation of 18,400 feet. The hole stands ready for the cement foundation on which the Fred Young Submillimeter Telescope (FYST, pronounced "feest") will one day rest. The foundation, which was designed in Chile, began construction in the fall of 2021 and is scheduled to be installed at the summit from May to June.

Intrinsically disordered regions (IDRs) of proteins, when tethered to folded domains, function either as flexible tails or as linkers between domains. Most IDRs are composed of a mixture of oppositely charged residues. Recent measurements of tethered polyampholytes have shown that arginine- and lysine-rich sequences tend to behave very differently from one another.

Scientists investigating the underside of the world's largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might contain a history of the ice sheet since its earliest beginnings. That would answer questions about what Antarctica was like before it froze, how climate change has affected it over its history, and how the ice sheet might behave as the world warms.

A new study led by Washington University in St. Louis uses a mathematical model and a global meta-analysis to highlight the cascading consequences of common parasitic infections in wild animals on terrestrial ecosystems.

There is a fierce debate raging in the deaf community.

The United Nations warned Monday that it would cost $20 billion to clean up an oil spill in the event of the "imminent" break-up of an oil tanker abandoned off Yemen.

Imagine a computer that can think as fast as the human brain while using very little energy. That's the goal of scientists seeking to discover or develop materials that can send and process signals as easily as the brain's neurons and synapses. Identifying quantum materials with an intrinsic ability to switch between two distinct forms (or more) may hold the key to these futuristic sounding "neuromorphic" computing technologies.

Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have used a new technique to better forecast the level of algal toxins that accumulate in Lake Erie every year.

When cells reproduce, the internal mechanisms that copy DNA get it right nearly every time. Rice University bioscientists have uncovered a tiny detail that helps understand how the process could go wrong.

Marine biologists from the Marine Biological Association (MBA) and the University of Southampton have led ground-breaking research which indicates that lethal collisions of whale sharks with large ships are vastly underestimated, and could be the reason why populations are falling.

An international team of researchers finds that the social media messages that resonate best with loyalty program members differ from the posts that work best with other customers. The finding could inform how best to craft social media campaigns aimed at either segment of a company's customer base.

Only about 15% of used clothes and other textiles in the United States get reused or recycled. The other 85% head straight to the landfill or incinerator. This wastes scarce resources, contributes to climate change and pollutes waterways.

In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.

Modern energy storage devices, such as supercapacitors and batteries, have highly temperature-dependent performance. If a device gets too hot, it become susceptible to "thermal runaway." Thermal runaway—or uncontrolled overheating—can ultimately result in explosions or fires. Adopting a well-informed thermal management strategy is necessary for the stable and safe operation of devices. To do this, it is important to understand how certain thermal properties, like heat capacity (Cp), dynamically change during charging and discharging.

A well-designed work-study program can boost human capital accumulation, with long-lasting, positive effects on participants' labor market outcomes, according to a study that analyzed "Yo Estudio y Trabajo" (YET), a program which provides students in Uruguay aged 16 to 20 with a first formal part-time work experience in state-owned companies for up to one year.

Get ready for a summer blockbuster.

Great white sharks aren't the only apex predators that are being seen more frequently around the region.

The electrochemistry designette is a purposefully developed design activity which allows students to demonstrate complex concepts and for instructors to impart a set of core skills to foster innovation. Developed by researchers from the Singapore University of Technology and Design (SUTD), this pedagogical tool was first introduced and published in 2019. It now has proven to be highly effective in allowing instructors to spot misconceptions in their students' understanding and provide prompt intervention.

A tropical spider species uses a "film" of air to hide underwater from predators for as long as 30 minutes, according to faculty at Binghamton University, State University of New York.

High economic value and excellent characteristics for breeding have enabled the Pacific white shrimp Litopenaeus vannamei to become one of the major aquaculture species in the world. However, in summer, continuous hot weather or periodic temperatures above 35 degrees Celsius leads to high mortality rates of the shrimp. Therefore, it is necessary to investigate the mechanisms of L. vannamei in response to high temperature.

If you're a fan of science fiction films, you'll likely be familiar with the idea of alternate universes—hypothetical planes of existence with different versions of ourselves. As far from reality as it sounds, it is a question that scientists have contemplated. So just how well does the fiction stack up with the science?

Metal-organic frameworks (MOFs) are promising as adsorbents for pollutants removal due to their high surface area, low density, tunable porosity and potential for increased adsorption capacities.

All forest fire smoke is bad for people, but not all fires in forests are bad.

What turned Venus into hell? It could have simply been a steadily warming sun, but new research suggests that volcanoes may have played a role in creating a runaway greenhouse effect. And the same history of active Volcanism almost killed the Earth, too.
