To describe something as slow and boring we say it's "like watching grass grow", but scientists studying the early morning activity of plants have found they make a rapid start to their day—within minutes of dawn.

Many mainstream depictions of immigration at the southern border of the United States paint a dark picture, eliciting imagery of violent gang members and child trafficking. But how many undocumented immigrants are really involved in this kind of activity? Many people may be surprised to learn the answer is far fewer than they think.

The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to watch these reactions under real-world conditions, an advance that may help researchers find ways to make concrete more sustainable.

The emerald ash borer, an invasive beetle native to Southeast Asia, threatens the entire ash tree population in North America and has already changed forested landscapes and caused tens of billions of dollars in lost revenue to the ash sawtimber industry since it arrived in the United States in the 1990s. Despite the devastating impact the beetle has had on forests in the eastern and midwestern...

As part of his Master's degree in civil engineering, an EPFL (Ecole Polytechnique Federale de Lausanne) student developed a connector for use in building sustainable structures. His initial project has expanded into an online program for designing bamboo furniture that's stylish, modular and customizable. And now his connector is being looked at for use by astronauts in outer space.

An international group of researchers has developed a new technique that could be used to make more efficient low-cost light-emitting materials which are flexible and can be printed using ink-jet techniques.

A new book written and illustrated by two recent alumnae of the University of Illinois Urbana-Champaign introduces third graders to the nuts and bolts of automotive mechanics and engineering.

The annual peak of global heat-trapping carbon dioxide in the air has reached another dangerous milestone: 50% higher than when the industrial age began.

Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their missions.

About 60 percent of drugs on the market have hydrophobic molecules as their active ingredients. These drugs, which are not soluble in water, can be difficult to formulate into tablets because they need to be broken down into very small crystals in order to be absorbed by the human body.

The threat of antibiotic resistance rises as bacteria continue to evolve to foil even the most powerful modern drug treatments. By 2050, antibiotic resistant-bacteria threaten to claim more than 10 million lives as existing therapies prove ineffective.

Extreme risk protection orders (ERPOs), also known as gun violence restraining orders, are civil court orders that grant temporary restrictions on purchasing and possessing firearms for individuals determined by a civil court judge to be at extreme risk of committing violence against themselves or others. A new study examined ERPO use in Oregon in the first 15 months after it was adopted. The...

"The big mystery about plankton is what controls its distribution and abundance, and what conditions lead to big plankton blooms," said Dennis McGillicuddy, Senior Scientist and Department Chair in Applied Ocean Physics and Engineering at the Woods Hole Oceanographic Institution (WHOI).

Customer loyalty programs have been around for decades and are used to help businesses, marketers and sellers build a sustainable relationship with their customers. But do they work? A recent study sought to find out and researchers learned that yes, customer loyalty programs do work, but perhaps not in ways most may assume.

Climate change and social inequality are two pressing issues that often overlap. A new study led by Princeton researchers offers a roadmap for cities to address inequalities in energy use by providing fine-grained methods for measuring both income and racial disparities in energy use intensity. Energy use intensity, the amount of energy used per unit floor area, is often used as a proxy for...

Puerto Rico is not ready for another hurricane season, let alone the effects of climate change, according to a new study that shows the island's outstanding capacity to produce record-breaking floods and trigger a large number of landslides.

For more than 25 years, Burmese pythons have been living and breeding in the Florida Everglades, where they prey on native wildlife and disrupt the region's delicate ecosystems. A new study shows that infrared cameras could make it easier to spot these invasive snakes in the Florida foliage, providing a new tool in the effort to remove them.

Scientists have invested great time and effort into making connections between a plant's genotype, or its genetic makeup, and its phenotype, or the plant's observable traits. Understanding a plant's genome helps plant biologists predict how that plant will perform in the real world, which can be useful for breeding crop varieties that will produce high yields or resist stress.

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy—and in the process identified a promising material for future devices that could turn heat on and off with the application of a magnetic "switch."

A more reliable way of estimating the size of megalodon shows the extinct shark may have been bigger than previously thought, measuring up to 65 feet, nearly the length of two school buses. Earlier studies had ball-parked the massive predator at about 50 to 60 feet long.

Carbon dioxide emissions in Los Angeles fell 33% in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study in Geophysical Research Letters. In the Washington, D.C./Baltimore region, emissions of carbon dioxide, or CO2, dropped by 34% during the same period.

More strategic and coordinated travel restrictions likely could have reduced the spread of COVID-19 in the early stages of the pandemic. That's according to new research published in Communications Physics. This finding stems from new modeling conducted by a multidisciplinary team of scientists and engineers at Rensselaer Polytechnic Institute.

Research between the University of Liverpool, UK and National Tsing Hua University (NTHU), Taiwan has revealed a new charge storage mechanism that has the potential to allow rechargeability within calcium-air batteries.

A new study co-authored by University of Central Florida researchers shows that pre-Columbian people of a culturally diverse but not well-documented area of the Amazon in South America significantly altered their landscape thousands of years earlier than previously thought.
