New algorithm helps read QR codes on uneven surfaces

Sometimes, we try to capture a QR code with a good digital camera on a smartphone, but the reading eventually fails. This usually happens when the QR code itself is of poor image quality, or if it has been printed on surfaces ...

Research collaboration examines Filipino migration dynamics

Over one million Filipinos leave their country every year to work. The high emigration figures not only concern the Philippine state, but also the economist Andreas Steinmayr. In July 2024, he resumed a long-standing collaboration ...

Problems with reproduction in birds

In birds and other species alike, pairs can face considerable difficulties with reproduction. Scientists at the Max Planck Institute for Ornithology in Seewiesen have now shown in an extensive analysis of 23,000 zebra finch ...

Breaking COVID-19's 'clutch' to stop its spread

Scripps Research chemist Matthew Disney, Ph.D., and colleagues have created drug-like compounds that, in human cell studies, bind and destroy the pandemic coronavirus' so-called "frameshifting element" to stop the virus from ...

HPV vaccine effective against cervical cancer

Women vaccinated against HPV have a significantly lower risk of developing cervical cancer, and the positive effect is most pronounced for women vaccinated at a young age. That is according to a large study by researchers ...

Coral's resilience to warming may depend on iron

How well corals respond to climate change could depend in part on the already scarce amount of iron available in their environment, according to a new study led by Penn State researchers. The study reveals that the combination ...

Mosquitos lost an essential gene with no ill effects

University of Maryland entomologists discovered that a gene critical for survival in other insects is missing in mosquitos—the gene responsible for properly arranging the insects' segmented bodies. The researchers also ...

Breastfeeding hormones make mothers happier

Oxytocin is one of the most important hormones between a mother and her baby. Researchers at Kyoto University and Azabu University in Japan report in a new study that the levels of oxytocin correspond to a mother's sensitivity ...

Researchers find recipe for forest restoration

The good news: Recognizing the incredible value of forests in providing habitat, storing carbon dioxide, purifying water and more, people around the world are working to restore forests destroyed in the past by human activities ...

Obese dogs helped by 'effective' weight loss trials

On average overweight dogs lose an average of 11% of their bodyweight when enrolled on a weight loss trial according to researchers who have conducted the largest international multi-centre weight study.

Five ways ancient India changed the world – with maths

It should come as no surprise that the first recorded use of the number zero, recently discovered to be made as early as the 3rd or 4th century, happened in India. Mathematics on the Indian subcontinent has a rich history ...

What a lake's colour can tell about its condition

With the help of satellite observations from 188 lakes worldwide, scientists at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) have shown that the warming of large lakes amplifies their colour. Lakes ...

Cnidarians remotely control bacteria

In modern life sciences, a paradigm shift is becoming increasingly evident: life forms are no longer considered to be self-contained units, but instead highly-complex and functionally-interdependent communities of organisms. ...

Do we read differently on paper than on a screen?

On a global scale, we are reading like never before and are spending more and more time glued to a screen. In fact, we read digital media every single day, whether it is on Facebook or in discussion forums. In total, there ...

New gravitational wave data analysis now underway

Penn State LIGO physicists are members of the LIGO-Virgo collaboration to detect and characterize gravitational waves. The collaboration now is completing a very exciting Second Observing Run that is drawing to a close on ...

The birdlife of an unforgiving paradise

When ECU wildlife ecologist Dr Rob Davis describes surveying birdlife on the island of New Britain as the hardest field work he's ever done, he's not exaggerating.
