AI-assisted technology detects nanoplastics in water—instantly

AI-assisted technology detects nanoplastics in water—instantly

A McGill-led research team has developed the first real-time, on-site technology capable of detecting and deciphering nanoplastics from all other particles in water, a capacity akin to being able to find a needle in a haystack within milliseconds.

Study reveals human degradation of tropical forests is greater than previously estimated

Study reveals human degradation of tropical forests is greater than previously estimated

Tropical forests are essential to sustain high biodiversity and mitigate climate change. They suffer from deforestation, the cutting and converting of forests for agriculture, mining, or infrastructure purposes. However, significant human impacts on the remaining forests that lead to their degradation are often overlooked.

Study finds ways to enhance transcription factor activity

Study finds ways to enhance transcription factor activity

Transcription factors regulate gene expression by binding specific sequences on DNA, which is an essential step to producing messenger RNAs from protein-coding genes. Denes Hnisz's lab, in collaboration with Martin Vingron's lab at the MPIMG, has discovered that human transcription factors don't typically use their full potential. Instead, important protein regions within transcription factors encode chemical features that generate submaximal transcriptional activity.

Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior

Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior

Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as work on complex materials, phase transitions and condensed matter physics.

Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect

Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect

Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly, causing an ultrafast perturbation of the magnetic order.

Motivated to disagree: What can be learned about rapid polarization from the Israeli judicial reform?

Motivated to disagree: What can be learned about rapid polarization from the Israeli judicial reform?

A recent study, conducted in the midst of last year's widespread protests in Israel, has uncovered extreme polarization in public opinion regarding the judicial reform introduced by Prime Minister Benjamin Netanyahu's government.

Ancient volcanic eruption not a catalyst for early Homo sapiens cultural innovations, researchers say

Ancient volcanic eruption not a catalyst for early Homo sapiens cultural innovations, researchers say

An international team of researchers from the Universities of Tübingen (Dr. Armando Falcucci), Siena, and Bologna analyzed the cultural remains left by groups of early Homo sapiens at Grotta di Castelcivita in southern Italy, dating back to before the major eruption known as the Campanian Ignimbrite.

New catalysts enable greener ester synthesis

New catalysts enable greener ester synthesis

A new catalyst may well catalyze a shift to greener chemistry. Chemists from Yokohama National University have successfully developed innovative catalysts containing two noble metals that demonstrate remarkable efficiency in ester-producing chemical reactions and utilize oxygen as the sole oxidant, making the process much more environmentally friendly and sustainable.

Exploring the radiative effects of precipitation on Arctic amplification and energy budget

Exploring the radiative effects of precipitation on Arctic amplification and energy budget

One of the key metrics for climate modeling is radiative forcing. Most climate models, including the general circulation models (GCMs), focus on the effects of different atmospheric factors on radiative forcing. However, there are still large uncertainties in satellite observations and multi-model simulations associated with some atmospheric factors.
