In a single stroke, Acting Attorney General Todd Blanche has dismantled this foundational understanding.
By executing a sweeping settlement with Donald Trump, Blanche committed an unprecedented dual assault on the Constitution,

After a security researcher published a series of unpatched bugs in Microsoft products, along with code to exploit them,
the company is now threatening to take legal action and call the cops on them.
Microsoft’s threat reignites a long-running argument over what responsibility, if any, security researchers have to disclose vulnerabilities affecting large and wealthy tech giants.
On Wednesday, Microsoft published a blog post criticizing the researcher, who goes by the handl…
British Prime minister condemns 'horrific antisemitic attack'
after four Jewish community ambulances set on fire
Keir Starmer has called for communities to “all stand together” in the face of an “horrific antisemitic attack”,
which saw four Jewish community ambulances set on fire.
The Metropolitan Police confirmed the incident is being treated as an antisemitic hate crime,
with CCTV showing three individuals setting light to an ambulance in the early hou…

Abstract: Rarefied hypersonic bow shocks over blunt bodies inflate as the Knudsen number increases, but it remains unclear whether this inflation is a simple shift and broadening of one common shock layer or a multi-scale change of the macroscopic and internal-energy fields. We address this question using direct simulation Monte Carlo (DSMC) data for Mach-10 flow over a circular cylinder in argon and nitrogen over \(Kn_\infty \approx 0.01\)--\(1\), together with a Mach-number sweep at \(Kn_\infty=0.01\). At low rarefaction, a ray-based density-gradient ridge gives a reproducible bow-shock location and agrees with an independent schlieren-based shock-wave-detection method. As \(Kn_\infty\) increases, this ridge is replaced by a broad kinetic compression layer, so the high-Knudsen cases are analysed using profile-based standoff and thickness metrics rather than by imposing a visual shock line. The Knudsen- and Mach-number sweeps separate two mechanisms. At fixed \(M_\infty\), the continuum normal-shock density ratio provides a useful low-rarefaction reference compression scale, whereas the measured standoff growth is governed primarily by the kinetic mean free path; the effective density thickness shows an intermediate minimum before increasing in the diffuse regime. At fixed low \(Kn_\infty\), changing \(M_\infty\) mainly changes compression strength and curvature, preserving a coherent attached-layer structure. Density-registered profiles and shock-attached proper orthogonal decomposition (POD) show that, within the present maximum-density-gradient registration, density becomes nearly rank one, whereas Mach number and thermal variables retain independent modal content. Rarefied bow-shock inflation is therefore a coupled compression--relaxation process, not a single-scale rescaling of a continuum-like shock.

The Justice Department is running out of attorneys.
The nation’s largest law office has repeatedly asked for delays in arguing its myriad cases,
and in doing so has accidentally divulged a massive staffing crisis raging underneath the surface.
In an obscure civil lawsuit dug up by independent journalist Scott MacFarlane, a Justice Department attorney revealed that
“the Appellate Section has lost over 40 percent of its attorneys since February 2025, due to retirement, r…
