A nine-day cushion
India's strategic petroleum reserve covers roughly nine days of net demand. Announcements of new facilities do not change that number today.
A radio glow that outlasted the flash by two years
AT2019ijn brightened in five days and faded within weeks. Nearly two years later its radio emission peaked at more than ten times that of anything it can be compared with, and that number, rather than an identification, is what the observation delivers.
A satirical party extracted four concessions
As the Cockroach Janta Party ended its protests it held four concrete items: a resignation, a compensation figure, an assurance of no punitive action against protesters, and a public apology from two security forces. Because each is addressed to a different institution, the outcome is auditable. The difficulty is that three of those institutions were the object of the protest.
A widely used evolutionary model fits infinitely many other answers equally well
State-dependent speciation and extinction models are how biologists ask whether a trait speeds up diversification. Two authors show that the hidden states routinely added to those models make every trait-independent scenario congruent with an infinite family of trait-dependent ones, and then name which part of that is fixable.
Brasilia refused the visas; the visit stayed on the calendar
Issuing a visa is a discretionary administrative power that requires no published reasons and that the applicant state cannot appeal. Brazil used that power against two US officials; Washington went on describing the same trip as “routine”. What the instrument actually binds will be visible in the 27-30 July window.
Close to half of the combination arm still had a response at six months
In people whose immune thrombocytopenia had already failed steroids and one further treatment, adding low-dose baricitinib to danazol took six-month durable response from 20.4 per cent to 45.4 per cent. What that is worth depends on the comparator, on who was blinded, and on how many patients the safety numbers rest on.
Friday closed green, the week closed red
Friday's closes did not change the week's direction. To see what price is weighing, look at spending rather than at a single session.
Micro's real product is four colors
The most functional part of a $230 keypad is the color of its keys: idle, thinking, complete, error. Those four states exist in any agent workflow; the setting that makes them visible lives only inside ChatGPT.
The breaking point for tidal wetlands sits at nine millimetres a year
Two decades of satellite observation put a number on where salt marshes and mangroves stop keeping up with the water. Above nine millimetres of relative sea-level rise a year the loss rate rises eightfold, and the buffer that might delay it runs on sediment supply.
The cargo line struck in the Caspian
The target set Zelenskyy described moves the war onto the cargo line in the Caspian. That line has no maritime alternative: because the Caspian is an enclosed basin, substitution runs towards land rather than towards another sea. The report gives no tonnage; what can be assessed is the direction of substitution, not its size.
