The U.S. Food and Drug Administration (FDA) today approved a controversial Alzheimer’s disease treatment for broad use—with caveats. The drug, an antibody called lecanemab, is the first to clearly slow cognitive decline in patients with early-stage disease, fueling excitement in the Alzheimer’s field and hope for patients and families. But its benefits appear modest, and it...

Bob McDonald's blog: Researchers propose a new idea for harvesting fresh water from ocean air, that could be a boon for for arid coastal...

As the war in Ukraine rages on, zoologist Anton Vlashenko is leading a team working to rescue and shelter thousands of...

Deforestation in the Brazilian Amazon rose 150 percent in December from the previous year, according to government figures released Friday, a final bleak report for far-right ex-president Jair Bolsonaro in his last month in office.

In the western, volcano-ringed highlands of Guatemala, Willy Barreno Minera keeps watch over the skies. As an ajq’ij , a daykeeper and spiritual guide, the stars and landscape help him keep track of the 260-day calendar that has ruled the life of his Maya K’iche’ community—an Indigenous group of about 1.6 million people—in Quetzaltenango for generations....

Drug works with the body’s immune system to clear amyloid protein buildup from the brainThe US Food and Drug Administration (FDA) has approved Lecanemab, a breakthrough drug to treat Alzheimer’s, that is manufactured by biotechnology companies Biogen and Eisai.The drug is an intravenously administered humanized monoclonal antibody that targets amyloid, the toxic protein in the brain linked to...

The ancient Roman Empire still makes its presence felt throughout Europe. Bathhouses, aqueducts, and seawalls built more than 2000 years ago are still standing—thanks to a special type of concrete that has proved far more durable than its modern counterpart. Now, researchers say they have figured out why Roman concrete remains so resilient: Quicklime used in the mix may have given the...

This video chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of...

Using a new method based upon comparing DNA mutation rates between parents and offspring, evolutionary biologists have revealed the average age of mothers versus fathers over the past 250,000 years, including the discovery that the age gap is shrinking, with women's average age at conception increasing from 23.2 years to 26.4 years, on average, in the past 5,000 years.

New research has uncovered that pollen preserved in 250 million year old rocks contain compounds that function like sunscreen, these are produced by plants to protect them from harmful ultraviolet (UV-B) radiation. The findings suggests that a pulse of UV-B played an important part in the end Permian mass extinction event.

Researchers can now detect the formation of keyhole pores, one of the most challenging defects common in additive manufacturing, with incredible accuracy.

A randomized, controlled trial of community gardening found that those who started gardening ate more fiber and got more physical activity -- two known ways to reduce risk of cancer and chronic diseases. They also saw their levels of stress and anxiety significantly decrease.

A U.S.-Brazilian study using time series satellite images from 2000 to 2021 reveals the vital role of Indigenous territories and protected areas for forest conservation in the Brazilian Amazon, as well as calls attention to the negative impacts of weakened governmental conservation policies in recent years.

Researchers suggest that rising levels of humanmade chemicals, accumulating in marine plankton, might be used to monitor the impact of human activity on ecosystem health and perhaps study links between ocean pollution and land-based rates of childhood and adult chronic illnesses.

Using multiplex base-editing, an approach that simultaneously modifies multiple sites in fungal genomes, chemical and biomolecular engineers coax fungi into revealing their best-kept secrets, ramping up the pace of new drug discovery.

Scientists have developed a photochemical process to simplify the synthesis of drug and chemical precursors known as diamines.

A research team has built and tested a new interlayer to prevent dissolution of the sulfur cathode in lithium-sulfur batteries. This new interlayer increases Li-S cell capacity and maintains it over hundreds of cycles.

An unexpected ancient manufacturing strategy may hold the key to designing concrete that lasts for millennia.

Eukaryotic cells—the ones that make up most life as we know it, including all animals, plants and fungi—are highly structured objects.

Over the last decade, there has been an effort by lawmakers to reduce incarceration in the United States without impacting public safety. This effort includes parole boards making risk-based parole decisions—releasing people assessed to be at low risk of committing a crime after being released.

More than 90% of the world's population is projected to face increased risks from the compound impacts of extreme heat and drought, potentially widening social inequalities as well as undermining the natural world's ability to reduce CO2 emissions in the atmosphere—according to a study from Oxford's School of Geography.

A recent study by Prof. Chong Kang's group from the Institute of Botany of the Chinese Academy of Sciences (CAS) has revealed a novel cold domesticated repair mechanism for DNA damage in rice, providing corresponding elite modules for the improvement of the chilling tolerance trait in rice with the codon repeats at a single site.

The Sun emitted a strong solar flare, peaking at 7:57 p.m. EDT on Jan. 5, 2023. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
