Want to make America healthy again? Stop fueling climate change
If you've been following recent debates about health, you've been hearing a lot about vaccines, diet, measles, Medicaid cuts and health insurance costs—but much less about one of the greatest threats to global public health: climate change.

Extreme events and impact statistics for unipotent actions on the space of lattices
This paper extends a recent extreme value law for horocycle flows on the space of two-dimensional lattices, due to Kirsebom and Mallahi-Karai, to the simplest examples of rank-$k$ unipotent actions on the space of $n$-dimensional lattices. We analyse the problem in terms of the hitting time and impact statistics for the unipotent action with respect to a shrinking surface of section, following the strategy of Pollicott and the first named author in the case of hyperbolic surfaces. If $k=n-1$, t…

Trajectory control of a suspended load with non-stopping flying carriers
This paper presents the first closed-loop control framework for cooperative payload transportation with non-stopping flying carriers. Building upon grasp-matrix formulations and internal force redundancy, we propose a feedback wrench controller that actively regulates the payload's pose while an optimization layer dynamically shapes internal-force oscillations to guarantee persistent carrier motion. Preliminary experimental results on multirotor UAVs validate the model assumptions, and numerica…

The CIVICUS Monitor has downgraded the United States of America’s civic space rating, reflecting a sharp deterioration of fundamental freedoms in the country. The People Power Under Attack report now rates the USA as “Obstructed” following a year of sweeping executive actions, restrictive laws, and aggressive crackdowns on free speech and dissent.

“The backsliding on rule of law and fundamental freedoms in the United States is truly alarming,” said Mandeep Tiwana...

Image reconstruction with the JWST Interferometer
Flying on board the James Webb Space Telescope (JWST) above Earth's turbulent atmosphere, the Aperture Masking Interferometer (AMI) on the NIRISS instrument is the highest-resolution infrared interferometer ever placed in space. However, its performance was found to be limited by non-linear detector systematics, particularly charge migration - or the Brighter-Fatter Effect. Conventional interferometric Fourier observables are degraded by non-linear transformations in the image plane, with the c…

Series D, Episode 02 - Power
VILA: Not too close. The gap is all connected with the thickness of the door. So what's the difference between Seskas and Hommiks?
PELLA: How do you know how thick it is?
VILA: By the stress pattern.

Big Bang Nucleosynthesis constraints on space-time noncommutativity
We consider the implications of the modified dispersion relations, due to the noncommutativity of the spacetime, for a photon gas filling the early Universe in the framework of the Big Bang Nucleosynthesis (BBN) processes, during the period of light elements formation. We consider three types of deformations present in the dispersion relations for the radiation gas, from which we obtain the low temperature corrections to the energy density and pressure. The cosmological implications of the modi…

When bushfires make their own weather
Bushfires are strongly driven by weather: hot, dry and windy conditions can combine to create the perfect environment for flames to spread across the landscape.
