Your toilet paper might give you cancer, according to scientists. Experts from the University of Florida warn that your toilet paper could contain toxic “forever chemicals,” also known as per-and polyfluoroalkyl substances (PFAs), which have previously been linked to certain cancers and even low sperm count.
Carbon nanotubes (CNTs) are cylindrical tube-like structures made of carbon atoms that display highly desirable physical properties like high strength, low weight, and excellent thermal and electrical conductivities. This makes them ideal materials for various applications, including reinforcement materials, energy storage and conversion devices, and electronics.
Despite such immense potential, however, there have been challenges in commercializing CNTs, such as their incorporation on plastic substrates for fabricating flexible CNT-based devices. Traditional fabrication methods require carefully controlled environments such as high temperatures and a clean room. Further, they require repeat transfers to produce CNTs with different resistance values.
More direct methods such as laser-induced forward transfer (LIFT) and thermal fusion (TF) have been developed as alternatives. In the LIFT method, a laser is used to directly transfer CNTs onto substrates, while in TF, CNTs are mixed with polymers that are then selectively removed by a laser to form CNT wires with varying resistance values.

The IUCr is a scientific union serving the interests of crystallographers and other scientists employing crystallographic methods.
Summary: After discovering the importance of cell metabolism in neurogenesis, researchers were able to increase the number of neurons in the brains of adult and elderly mice.
Source: University of Geneva.
Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood.

Once aboard, the four-member team faces a busy workload of more than 200 experiments and technology demonstrations, ranging from studies of human cell growth in space to controlling combustible materials in microgravity.
Some of the research will help pave the way for future long-duration human expeditions to the Moon and beyond under NASA’s Artemis program, its successor to Apollo, the U.S. space agency said.
The ISS crew also is responsible for performing maintenance and repairs aboard the station, and to prepare for the arrival and departure of other astronauts and cargo payloads.
My new story on the Alt-Right vs. transhumanism!
In his first of a five-part essay series on transhumanism, a leader of the movement, Zoltan Istvan, discusses what lies behind the heightened interest in transhumanist ideas.
The Big Bang is the name we have given to the moment at which the Universe began. While the idea is well known, it is often badly misunderstood. Even people with a good grasp of science have misconceptions about it. For instance, a common question is, “Where did the Big Bang happen?” And the answer to that question is a surprising one. So, let’s dive into it and try to understand where the misunderstanding arises.
When people are told of the Big Bang, they are commonly told that “all of the mass of the universe was packed into a point with zero volume called a singularity.” The singularity then “exploded,” expanding and cooling and eventually resulting in the Universe we see today. People draw from their own experience and analogize the Big Bang with something like a firecracker or a grenade — an object that sits in a location, then explodes, dispersing debris into existing space. This is a completely natural and reasonable mental image. It is also completely wrong.

First Publicly Known. Expect to see most countries have one by 2030. In Charge, 2050s.
Romanians will be able to send their ideas through an accompanying website (ion.gov.ro) as well as on social media and some in-person locations. Ion will then synthesize their contributions for the government to consider, according to the coordinator of the research team, Nicu Sebe. Users won’t, however, receive a response from Ion itself.
Instead, Research and Innovation Minister Sebastian Burduja, whose office is overseeing the project, explained that Ion will analyze the information it receives and draw up reports about Romanians’ priorities.
