OpenAI made a big splash when it showed off its new video generator Sora last month.

The text-to-video model can be used to “create videos of up to 60 seconds featuring highly detailed scenes, complex camera motion, and multiple characters with vibrant emotions,” according to OpenAI CEO Sam Altman.

And with stunning results, from a camera gliding through a snowy scene to photorealistic wooly mammoths.

This video shows the fly model reproducing a flight maneuver (spontaneous turning) of a real fly, executing commands to walk at a speed of 2 cm/s while turning left and right, and the model imitating a walking trajectory of the real fruit fly, which includes walking at different speeds, turning and briefly stopping.

By infusing a virtual fruit fly with artificial intelligence, Janelia and Google DeepMind scientists have created a computerized insect that can walk and fly just like the real thing.

Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces and pressures inside a subatomic particle for the first time.

Lurking some nine billion light years away from Earth is what appears to be a so-called cosmic megastructure in the shape of an enormous ring. It’s so large that its existence should be impossible, according to new research reported on by The Guardian, challenging a fundamental assumption of our understanding of the Universe.

Known as the “Big Ring,” the structure spans an astonishing 1.3 billion light years in diameter — a significant portion of the observable Universe’s estimated size of 94 billion light years. By contrast, the largest known galaxy is a “mere” 16 million light years across. If it were visible in the night sky to the naked eye, the Big Ring would be equal in diameter to fifteen full moons. Succinctly put: it’s unfathomably huge.

The unpublished findings, presented at the annual meeting of the American Astronomical Society on Thursday, add to a growing list of inexplicably large structures that remain confounding — if not controversial — to scientists.

Cerebral cavernous malformations occur in 0.5% of the population; 85% are sporadic, and 15% are familial or radiation-induced. Several genetic variants, including variants in CCM, drive their development. Read the full review:

Discover a fascinating case study on Superficial Temporal Artery-to-Middle Cerebral Artery Bypass for Ischemic Stroke with Blood Pressure-Dependent Symptoms! 🧠

The efficacy of extracranial-intracranial (EC-IC) bypass in preventing ischemic stroke progression and recurrence is controversial. As per the current hypothesis, EC-IC bypass is most beneficial for patients with persistent hemodynamic insufficiency. Hence, various approaches have been used to evaluate hemodynamic insufficiency, including repeated single photon emission CT (SPECT) imaging or continuous monitoring of cerebral flow with transcranial Doppler ultrasound (TCD). However, both modalities are time-and resource-intensive. In this report, we discuss how EC-IC bypass turned out to be beneficial for a patient presenting with blood pressure-dependent severe aphasia and right hemiparesis due to middle cerebral artery (MCA) occlusion that failed thrombectomy. CT perfusion (CTP) scan at admission demonstrated a persistent volume of delayed perfusion without core infarct.
