Ernesto Di Maio is severely allergic to the yeast in leavened foods. “I have to go somewhere and hide because I will be fully covered with bumps and bubbles on the whole body,” he says. “It’s really brutal.”
Di Maio is a materials scientist at the University of Naples Federico II where he studies the formation of bubbles in polymers like polyurethane. He’s had to swear off bread and pizza, which can make outings in Italy a touch awkward. “It’s quite hard in Naples not to eat pizza,” he explains. “People would say, ‘Don’t you like pizza? Why are you having pasta? That’s strange.’”
So Di Maio put Iaccarino and another graduate student, Pietro Avallone, to work on a project to make pizza dough without yeast. The results of this scientific and culinary experiment are published in Tuesday’s edition of Physics of Fluids. Di Maio pulled in another colleague: chemical engineer Rossana Pasquino who studies the flow of materials, everything from toothpaste to ketchup to plastics. “Pizza [dough] is a funny material,” she explains, “because it flows, but it has to be also like rubber. It has to be elastic enough [when it’s cooked] to be perfect when you eat it.” — I had to post this because I love Pizza.

If the trials go well, it could become a longevity treatment for civilians too.
The U.S. military is developing an anti-aging pill that is designed to inhibit performance reduction that comes with aging.
Your space questions, answered.
Every week, the readers of our space newsletter, The Airlock, send in their questions for space reporter Neel V. Patel to answer. This week: time dilation during space travel.
Elon Musk is one of the revolutionary figures in the world. Almost all of his ventures, such as SpaceX, Tesla and The Boring Company, are about making a difference in their own right. Musk has been a champion for all things alternative, whether it comes to cars or currency. However, he could trigger another great replacement.
From $10,000 per kg, possibly down to $15 per kg to orbit.

“Time-resolved photon-counting plays an indispensable role in precision metrology in both classical and quantum regimes. In particular, time-correlated single-photon counting (TCSPC) has been the key enabling technology for applications such as low-light fluorescence lifetime spectroscopy and photon counting time-of-flight (ToF) 3D imaging. However, state-of-the-art TCSPC single-photon timing resolution (SPTR) is limited in the range of 10–100 ps by the available single-photon detector technology. In this paper, we experimentally demonstrate a time-magnified TCSPC (TM-TCSPC) that achieves an unprecedentedly short SPTR of 550 fs for the first time with an off-the-shelf single-photon detector. The TM-TCSPC can resolve ultrashort pulses with a 130-fs pulsewidth difference at a 22-fs accuracy. When applied to photon counting ToF 3D imaging, the TM-TCSPC greatly suppresses the range walk error that limits all photon counting ToF 3D imaging systems by 99.2 % (130 times) and thus provides unprecedentedly high depth measurement accuracy and precision of 26 {\mu}m and 3 {\mu}m, respectively.”
The 1kW pico-hydro generation system can be used with factory drainage systems and irrigation canals. According to the manufacturer, it is made with 3D-printed sustainable materials based on recycled plastics and is able to generate electricity even with a small stream of water. Solar and storage may be linked to the system to ensure stable power supply.
It would take 15 billion years for the clock that occupies Jun Ye’s basement lab at the University of Colorado to lose a second—about how long the uni.
Using density functional theory calculations and the Greens’s function formalism, we report the existence of magnetic edge states with a non-collinear spin texture present on different edges of the 1T’ phase of the three monolayer transition metal dichalcogenides (TMDs): MoS$_2$, MoTe$_2$ and WTe$_2$. The magnetic states are gapless and accompanied by a spontaneous breaking of the time-reversal symmetry. This may have an impact on the prospects of utilizing WTe$_2$ as a quantum spin Hall insulator. It has previously been suggested that the topologically protected edge states of the 1T’ TMDs could be switched off by applying a perpendicular electric field. We confirm with fully self-consistent DFT calculations, that the topological edge states can be switched off. The investigated magnetic edge states are seen to be robust and remains gapless when applying a field.
Tesla CEO Elon Musk polled Twitter on Saturday, asking whether a new social media platform should be created to challenge Twitter and sparking speculation that the billionaire might be the one to do so.
In a series of tweets on Friday, the Space X founder asked if the time has come for a new platform to replace Twitter, and whether users thought the company ‘adhered to free speech principles.’
He said that, because Twitter serves as ‘the de factor public town square,’ a failure to promote free speech on the app would undermine democracy.
