The Lyman-$α$ Forest from LBGs: First 3D Correlation Measurement with DESI and Prospects for Cosmology
The Lyman-$α$ (Ly$α$) forest is a key tracer of large-scale structure at redshifts z > 2, traditionally studied using spectra of quasars. Here, we explore the viability Lyman Break Galaxies (LBGs) as alternative background sources for Ly$α$ forest studies. We analyze 4,151 Ly$α$ forest skewers extracted from LBG spectra obtained in the DESI pilot surveys in the COSMOS and XMM-LSS fields. We present the first measurement of the Ly$α$ forest auto-correlation function derived exclusively from…

Breaking down ‘EchoLeak’, the First Zero-Click AI Vulnerability Enabling Data Exfiltration from Microsoft 365 Copilot.
Aim Labs reported CVE-2025-32711 against Microsoft 365 Copilot back in January, and the fix is now rolled out.
This is an extended variant of the prompt injection exfiltration attacks we've seen in a dozen different products already:
an attacker gets malicious instructions into an LLM system which cause it to access private data and then embed that in …

Anarchists: often said to be frighteningly violent and/or unhinged because maybe a handful of times in the nineteenth and twentieth centuries they used bombs or guns to target literal blood-soaked tyrants and help usher in the end of feudalism.
People who manufacture, sell, buy, and use guns and bombs daily to kill another nation's conscripted commoners along with a healthy dose of completely innocent civilians, who perpetuate genocide and other war crimes every year: heroes, I guess? "Civilized?" "Great leaders."
The distinction of course is that one obeys the "rules of society" about who it's okay to wantonly murder (whose "lives matter," in fact) while the other does not, and you've been trained to believe that anyone who violates those rules must not have any principles at all. All along, the rules have been crap.

A while ago the media reported that most of the long-distance "suburban" trains between #Wrocław and #Poznań will be discontinued, and instead one will have to change trains midway. Irrespective of whether it's actually going to happen, let's consider it.
As you can probably tell by now, I'm not a stranger to changing trains. In fact, there are some direct connections that I do criticize. For example:
• Poznań — Szczecin — Świnoujście, where arriving at Szczecin Główny and turning back to leave the city is a waste of time. It's better to change trains at Szczecin Dąbie.
• Poznań — Krzyż — Kostrzyn, where instead of using a single railbus, you can use a larger EMU for the Poznań — Krzyż segment, and a smaller DMU for Krzyż — Kostrzyn (in fact, only recently the "direct" Poznań — Kostrzyn train involved just that, but it was supposed to be temporary).
However, good matches are the key. Say:
1. Max 10 minutes (when there are no delays) from one train to the other.
2. "Door-to-door" transfer — without having to carry all your luggage across platforms.
3. Reliable connection — if one train is delayed, the other train waits for it (or there are so many alternatives that it doesn't have to).
Can such a thing happen on Poznań — Wrocław route? I have my doubts.
I've been using these trains for years, and I can say this: there is no effort to match train from/to Poznań with other trains in Wrocław. Sometimes the trains depart 10 minutes before the first train from Poznań arrives, sometimes I need to transfer in 10 minutes, and sometimes I have to wait over an hour. And the same in the other direction.
Perhaps things would actually improve if the route is split. Perhaps people would actually care. Maybe even the trains would be fitted better to the timetable in Wrocław. But I find it hard to believe.
EDIT: One final thought — since there is no real reason to split these connections (except for profiteering), why make travellers' lives harder?

When Engineering Outruns Intelligence: A Re-evaluation of Instruction-Guided Navigation
Large language models (LLMs) are often credited with recent leaps in ObjectGoal Navigation, yet the extent to which they improve planning remains unclear. We revisit this question on the HM3D-v1 validation split. First, we strip InstructNav of its Dynamic Chain-of-Navigation prompt, open-vocabulary GLEE detector and Intuition saliency map, and replace them with a simple Distance-Weighted Frontier Explorer (DWFE). This geometry-only heuristic raises Success from 58.0% to 61.1% and lifts SPL from…

Shoot First laws in the United States lead to substantial increases in violence
and the senseless loss of hundreds of lives every year.
Research shows that these laws have increased gun homicides by up to 11 percent nationally,
translating to more than 700 deaths annually.
Some Shoot First states have seen even steeper increases, with those rates rising by 30 percent or more in Alabama, Florida, and Missouri.
Adolescents experience higher rates of gun homicides…

The Dangers of Shooting First: "Stand Your Ground" Laws Are a License to Kill
Shoot First laws, also known as Stand Your Ground laws, allow a person to use deadly force in a confrontation without any duty to retreat.

Senator Bernie Sanders of Vermont, an Independent,
who serves as the ranking member on the health, education, labor and pensions (Help) committee,
said that Robert F Kennedy Jr’s attempt to fire Susan Monarez was “outrageous”.
“The Sen. HELP Committee must hold a hearing with Kennedy & the CDC Director as soon as possible.
Vaccines save lives. Period,” Sanders said on X.
As Monarez is a Senate-confirmed official
