Hummingbird bills -- their long, thin beaks -- look a little like drinking straws. But new research shows just how little water, or nectar, that comparison holds. Scientists have discovered that the hummingbird bill is surprisingly flexible. While drinking, a hummingbird rapidly opens and shuts different parts of its bill simultaneously, engaging in an intricate and highly coordinated dance with its tongue to draw up nectar at lightning speeds.

Spotted lanternflies -- invasive insects that first landed in the United States a decade ago -- are emerging earlier and staying active later each year, according to an analysis of citizen-science data by researchers. This longer life cycle and shift in activity may be driven in part by cities and their warmer climates. Read more ›

New research has found that women who have had both ovaries surgically removed before the age of 50 and carry a variant of the apolipoprotein gene, the APOE4 allele, are at high risk of late-life Alzheimer disease (AD). Use of hormone therapy mitigates this risk. Read more ›

Colorful auroras appeared around Japan's Honshu and Hokkaido islands on May 11, 2024, sparked by an intense magnetic storm. Usually, auroras observed at low latitudes appear red due to the emission of oxygen atoms. But on this day, a salmon pink aurora was observed throughout the night, while an unusually tall, blue-dominant aurora appeared shortly before midnight. Read more ›

When women are pregnant and nurse their babies, their bodies change and various organs, such as the breasts or the immune system, are adapted to ensure the health of both mother and child. This happens throughout evolution in all mammals. An international research team now reports the surprising finding that the intestine also changes completely in pregnant and nursing females, resulting in a doubling of the intestinal surface area and...

Analysis of cheek swabs taken from pregnant women revealed a potential epigenetic biomarker for preeclampsia, a potentially life-threatening condition that often leads to preterm births. While a clinical trial is needed to confirm the results, a study offers hope that a simple test can be developed to identify preeclampsia earlier in pregnancy. Currently preeclampsia is usually identified by symptoms, such as abnormally high blood pressure, which only appear in the... Read more ›

A research team has made exceptional discoveries on prehistoric archery from the early Neolithic period, 7,000 years ago. The well organic preservation of the remains of the Cave of Los Murcielagos in Albunol, Granada, made it possible for scientists to identify the oldest bowstrings in Europe, which were made from the tendons of three animal species. The use of olive and reed wood and birch bark pitch in the making... Read more ›

Despite the massive hype surrounding Power-to-X (PtX), most of the world's announced green hydrogen projects lack financing. The market is deemed far too risky by stakeholders. And, there are many potential pitfalls. According to the authors of a new study actors must be 'compelled' to invest in a genuinely green manner. Read more ›

A new study provides the first cellular evidence that making new brain cells in adults supports verbal learning and memory, which enables people to have conversations and to remember what they hear. This discovery could point to new approaches to restore cognitive function. The study relied on brain tissue from patients with drug-resistant cases of mesial temporal lobe epilepsy (MTLE), which involves seizures as well as accelerated cognitive decline. Read more ›

Avian influenza viruses typically require several mutations to adapt and spread among humans, but what happens when just one change can increase the risk of becoming a pandemic virus? A recent study reveals that a single mutation in the H5N1 'bird flu' virus that has recently infected dairy cows in the U.S. could enhance the virus' ability to attach to human cells, potentially increasing the risk of passing from person...
