Rompani et al. employ single-cell-initiated transsynaptic tracing to decipher patterns of input integration in the thalamus. They show that individual cells in the lateral geniculate nucleus integrate retinal inputs in three distinct modes, each exhibiting different degrees of specialization.

Astronomers have measured the mass of a lone white dwarf star for the first time. This type of smoldering stellar remnant is formed at the end of the lives of low-mass stars and will be what the sun leaves behind when it dies in around 5 billion years.
The Hubble Space Telescope measured the mass of a white dwarf designated LAWD 37, which burned out over 1 billion years ago. In the work, scientists used a phenomenon first predicted in 1915 by Albert Einstein called “gravitational lensing,” which involves the bending of light by objects of great mass. The team determined that LAWD 37 has a mass around 56% that of the sun. The finding confirms current theories of how these stellar remnants form and evolve. This particular white dwarf is well studied because it is relatively close to Earth at just 15 light-years away in the constellation of Musca.
China has urged “cool-headed” handling of a dispute over a giant Chinese balloon heading for the eastern US.
US Secretary of State Antony Blinken earlier called off a visit to Beijing, saying the “surveillance” balloon’s presence was “an irresponsible act”.

If Mimas has an ocean, it represents a new class of small, ‘stealth’ ocean worlds with surfaces that do not betray the ocean’s existence.

Although early detection of many types of cancer has contributed to the recent increases in cancer survival rates, the survival rate for brain tumors has remained almost unchanged for over 20 years. Partly this is due to their late detection. Physicians often discover brain tumors only after the onset of neurological symptoms, such as loss of movement or speech, by which time the tumor has reached a considerable size. Detecting the tumor when it is still small, and starting treatment as soon as possible, should help to save lives.
One possible sign that a person has a brain tumor is the presence of tumor-related extracellular vesicles (EVs) in their urine. EVs are nano-sized vesicles involved in a variety of functions, including cell-to-cell communication. Because those found in brain cancer patients have specific types of RNA and membrane proteins, they could be used to detect the presence of cancer and its progression.
Elon Musk said Twitter will introduce an early version of a long-teased new feature on the platform allowing creators to be paid for their tweets as soon as next week.
Musk responded to a tweet on Tuesday by a user who said Twitter’s co-tweet feature which lets users co-author tweets together is “stupid af” to which Musk responded: “You’re welcome. Axed them yesterday to focus on enabling writers to add essays as attachments to tweets.
Combined with improvements to creator subscriptions (fka superfollow), you will be able to publish directly on Twitter & get paid for it.

It was a life-changing day for 12 patients living in the United States when they found that their cancer had vanished, thanks to a small clinical trial. Of the total number of patients, these were the patients who completed the trial.
The New York Times reported that a drug named Dostarlimab was administered to these patients — all suffering from rectal cancer — over six months. All 12 patients entered remission after the period.
