California weather was heating up and winds were shifting Thursday as more than 14,000 firefighters battled wildfires up and down the state, including a major blaze they hoped to keep out of the Lake Tahoe resort region.

Is Christianity under attack in the United States? It depends on whom you ask. Some church leaders and politicians claim recent LGBTQ progress—such as the 2015 U.S. Supreme Court ruling guaranteeing same-sex couples the right to marry—is an attack on Christianity.

Setting a price just below a round number ($39.99 instead of $40) may lead consumers into thinking a product is less expensive than it really is—but it can sometimes backfire on sellers, a new study shows.

A Southwest Research Institute (SwRI) experiment was performed aboard Blue Origin's New Shepard suborbital rocket today, which launched from Van Horn, Texas. Five variations of the tapered liquid acquisition device (LAD), which is designed to safely deliver liquid propellant to a rocket engine from fuel tanks, were aboard the rocket to evaluate their performance in microgravity.

It's a cloudy July afternoon in Cambridge, Massachusetts, and MIT Edgerton Center Instructor Amanda Mayer is using brightly-colored plastic to build proteins. She takes a small yellow block and moves it to the end of a chain of blue and green ones, clicking it into place. "Congratulations," she says to the four high school students guiding her hand over Zoom. "You've all become synthetic biologists."

Walking past a corner bakery, you may find yourself drawn in by the fresh smell of sweets wafting from the front door. You're not alone: The knowledge that humans make decisions based on their nose has led major brands like Cinnabon and Panera Bread to pump the scents of baked goods into their restaurants, leading to big spikes in sales.

The human body can be genetically inclined to attack its own cells, destroying the beta cells in the pancreas that make insulin, which helps convert sugar into energy. Called Type 1 diabetes, this disorder can occur at any age and can be fatal if not carefully managed with insulin shots or an insulin pump to balance the body's sugar levels.

In its search for signs of ancient microbial life on Mars, NASA's Perseverance rover is once again preparing to collect the first of many rock core samples that could eventually be brought to Earth for further study.

A new study finds that U.S. residents struggle to understand terms frequently used by scientists to describe climate change. Study participants said some of the terms were too complex to understand. Other terms were misunderstood in the context of climate change. Participants suggested simpler, alternative language.

"Skin electronics" are thin, flexible electronics that could be mounted onto the skin. While it may sound like something out of science fiction, it is anticipated that soon such devices will serve in a wide range of applications such as health monitoring, health diagnosis, virtual reality, and human-machine interface.

Determining the 3-D shapes of biological molecules is one of the hardest problems in modern biology and medical discovery. Companies and research institutions often spend millions of dollars to determine a molecular structure—and even such massive efforts are frequently unsuccessful.

What do frog eggs have in common with anti-aging creams? Their success depends on a group of chemical compounds called retinoids, which are capable of generating and re-generating tissues.

Traditionally, natural resources in the United States have been managed for productive uses, meaning resource extraction. To acquire and maintain leases of publicly owned resources such as oil and gas, timber, and rangelands, the resources must be put to certain "productive uses." Purchasing rights to natural resources to conserve them, rather than for extraction, is typically not an option.

As climate change continues to do more damage to our planet, scientists are working to find more efficient and cleaner ways to power the earth. One appealing alternative to common petrochemical processes that generate significant greenhouse gasses and other waste products could come from biological systems.

From seismic surveys and Navy sonar to fisheries and shipping, many human activities in the ocean environment cause short-term changes in the behaviors of marine mammals. A longstanding challenge for scientists and regulatory agencies alike has been to understand the biological significance of those changes in terms of their overall impact on affected populations of animals.

The NASA/ESA/CSA James Webb Space Telescope has successfully completed its final tests and is being prepared for shipment to its launch site at Europe's Spaceport in French Guiana.

The world's oceans are becoming increasingly stressful places for marine life, and experts are working to understand what this means for the future. From rising temperatures; to acidification as more carbon enters the waters; to changes in the currents; the challenges are multifaceted, making experiments and projections difficult.

Climate change is happening and accelerating. Earth will continue to warm. And these changes are unequivocally caused by human activities. Those are among the conclusions of the report published by the International Panel on Climate Change (IPCC), with University of Hawaiʻi at Mānoa Assistant Professor of oceanography Malte Stuecker as a contributing author.

Up to 95 percent of Earth's ocean surface will have changed by the end of the century unless humanity reins in its carbon emissions, according to research published Thursday.

A large fire tore through a scientific space research centre in northern Sweden on Thursday, destroying part of the rocket launch pad, officials said.

Mechanical flexibility is a key factor determining the stability and durability of porous carbon materials. The compressive brittleness of porous carbon materials has been well resolved. However, reversible stretchability property remains a major challenge due to the weak connections of the three-dimensional porous carbon networks.

As scientists continue to explore the wide-ranging effects of heat stress on the health of dairy cattle, a new study by researchers from the University of Florida, published in the September issue of JDS Communications, adds to the growing understanding of the negative influences of heat stress, not just throughout the lifespan but across generations.

Much like in human society, female hummingbirds have taken it into their own hands to avoid harassment. By watching white-necked Jacobin hummingbirds in Panama, researchers discovered that over a quarter of females have the same brightly colored ornamentation as males, which helps them avoid aggressive male behaviors during feeding, such as pecking and body slamming. This paper appears August 26 in the journal Current Biology.

New research has shed light on when plants first evolved the ability to respond to changing humidity in the air around them, and was probably a feature of a common ancestor of both flowering plants and ferns.

For the first time, Northwestern University engineers have created a double layer of atomically flat borophene, a feat that defies the natural tendency of boron to form non-planar clusters beyond the single-atomic-layer limit.
