Researchers who study shark attacks on humans have experimented with a variety of methods for preventing harmful encounters. There is no single solution, but layered defenses can help keep swimmers and surfers safe, which are shown in this graphic.

Neurons of the amygdala display intrinsic variations in epigenetic state. An increase in histone acetylation leads to an increase in neuronal excitability and synaptic remodeling, which primes neurons to become part of an engram—neurons that “store” a memory—during learning.

A 2024 Science study in mice identifies chromatin plasticity as a novel form of plasticity important for information encoding.

Pantropical tree rings show small effects of drought on stem growth Increasing drought pressure under anthropogenic climate change may jeopardize the potential of tropical forests to capture carbon in woody biomass and act as a long-term carbon dioxide sink. To evalua...

How do tropical #trees deal with droughts? The answer is published today in @science.org

Our pantropical #treering analysis revealed 2.5% growth reduction during #drought years. Yet, growth declined by >10% in 1/4 of 500 study sites, and in hotter & drier regions.

Advancing science- and evidence-based AI policy Policy must be informed by, but also facilitate the generation of, scientific evidence

What kind of AI governance do we need? Our new piece in @science.org answers this: we need policy grounded in evidence and built to generate more of it. Evidence-based policymaking is not a slogan—it’s a design challenge for democratic governance in the age of AI www.science.org/doi/10.1126/... 🧵

A molecular machine directs the synthesis of a catenane Precise mechanical manipulation of molecules is inherently difficult owing to random thermal motion. Although directed movement on the molecular scale has been achieved, using it to impose specific—es...

Oh, you have a machine that goes bing? Well guess what chemsky? @science.org has a machine that goes RING! On the cover this week, Michael Kathan’s group use a Feringa-type rotary motor to produce catenanes! 🧪

www.science.org/doi/10.1126/...

This illustration shows consecutive stages during operation of a molecular catenating machine.

This week in Science, researchers report an artificial molecular motor that can twist a molecular thread to form a mechanically interlocked molecule. The approach creates opportunities to fabricate mechanically interlocked molecules with precise structural control.

The Integrated Food Security Phase Classification partnership has issued an alert about the “worst-case scenario” unfolding in the Gaza Strip.

Contrarian climate assessment from U.S. government draws swift pushback Researchers say DOE report cherry picks data to downplay threat of greenhouse gases

So what makes a climate assessment? In short: not this new Energy Dept report, which rehashes contrarian greatest hits with areas of known uncertainty -- that climate scientists talk about all the time.

It's all a little grim. Who needs 721 authors when you have 5?
