Real Risk to Youth Mental Health Is ‘Addictive Use,’ Not Screen Time Alone, Study Finds
Researchers found children with highly addictive use of phones, video games or social media were two to three times as likely to have thoughts of suicide or to harm themselves.

The refined local Donaldson-Thomas theory of curves
We solve the $K$-theoretically refined Donaldson-Thomas theory of local curves. Our results avoid degeneration techniques, but rather exploit direct localisation methods to reduce the refined Donaldson-Thomas partition function to the equivariant intersection theory of skew nested Hilbert schemes on smooth projective curves. We show that the latter is determined, for every Young diagram, by three universal series, which we compute in terms of the 1-leg $K$-theoretic equivariant vertex. In the r…

Strichartz estimates for the generalized Zakharov-Kuznetsov equation on $\mathbb{R} \times \mathbb{T}$ and applications
In this article, we address the Cauchy problem associated with the $k$-generalized Zakharov-Kuznetsov equation posed on $\mathbb{R} \times \mathbb{T}$. By establishing an almost optimal linear $L^4$-estimate, along with a family of bilinear refinements, we significantly lower the well-posedness threshold for all $k \geq 2$. In particular, we show that the modified Zakharov-Kuznetsov equation is locally well-posed in $H^s(\mathbb{R} \times \mathbb{T})$ for all $s > \frac{3}{8}$.

'In the local data that the audit examined from three [THREE] police forces, they identified clear evidence of “over-representation among suspects of Asian and Pakistani-heritage men”.
'However, the review also criticised the ongoing failure to collect ethnicity at a national level, with it not recorded for two-thirds of perpetrators, making it impossible “to provide any accurate assessment from the nationally collected data”.'
Not so conclusive then.

Toponia at the HL-LHC, CEPC, and FCC-ee
The discovery of a pseudoscalar toponium state at the Large Hadron Collider (LHC) opens a new avenue for the study of a novel class of QCD bound states with comparable formation and decay times. Compared to charmonium and bottomonium, toponium is a more loosely bound state, resembling a hydrogen atom of the strong interactions, although it appears as a broader resonance. We compute the masses and annihilation decay widths of the lowest $S$-wave ($η_t$, $ψ_t$) and $P$-wave ($χ_{t0}$, $χ_{t1}…

Revealing Limitation in the Standard Cosmological Model: A Redshift-Dependent Hubble Constant from Fast Radio Bursts
A major issue in contemporary cosmology is the persistent discrepancy, known as the Hubble tension, between the Hubble constant ($H_0$) estimates from local measurements and those inferred from early-Universe observations under the standard $Λ$ cold dark matter ($Λ$CDM) paradigm. Recent advances have identified fast radio bursts (FRBs), a class of extragalactic phenomena observable at considerable redshifts, as a promising observational tool for probing late-time cosmology. In this study, we …

The mostly European demonstrators, accusing Israel of
"genocide," were met with fierce opposition from Egyptian locals, who pelted them with clubs and water bottles, forcing them back and halting their advance toward the border.“

The mostly European demonstrators, accusing Israel of “genocide,” were met with fierce opposition from Egyptian locals, who pelted them with clubs and water bottles, forcing them back and halting their advance toward the border. Many of the activists have since taken to social media claiming they were beaten, had their passports stolen, and are now stranded in Egypt. Several are pleading online for help from their embassies. One Egyptian pundit remarked: “There’s a reason Egypt has a huge wall and doesn’t let any Gazans in. What made these people think they could just ‘march to Gaza’ via Egypt?” Egyptian authorities have yet to issue an official statement."
