Recent advances have put some interesting possibilities on the table when it comes to tackling hair loss, from topical solutions packed with stem cells, to 3D-printed hair farms, to growing hair with a patient’s own cells. Scientists in China are now throwing another one into the mix that uses a dissolvable microneedle patch to stimulate hair growth, with the technology proving high effective in mouse models of hereditary pattern baldness.

Led by scientists at China’s Zhejiang University, the researchers set out to develop new treatments for the most common of hair loss conditions: male-and female-pattern baldness, also known as androgenic alopecia. The scientists sought to tackle the issue by focusing on what they say are the primary mechanisms behind this, namely oxidative stress and poor circulation.

This relates to the combination of accumulating reactive oxygen species in the scalp that kill off the cells behind new hair growth, and a lack of blood vessels around the follicles to provide them with nutrients and essential molecules. In this way, the team hoped to come up with a two-pronged approach to androgenic alopecia, and their solution starts with previous research carried out on liver injuries and Alzheimer’s.

But astronomer Tiger Hsiao of National Tsing Hua University says we might be looking for the wrong thing. In a new study, he and colleagues set out to calculate whether it would also be possible to use a Dyson sphere around a black hole. They analyzed black holes of three different sizes: those five, 20 and 4 million times the mass of our Sun. These, respectively, reflect the lower and upper limits of black holes known to have formed from the collapse of massive stars—and the even more enormous mass of Sagittarius A*, the supermassive massive black hole thought to lurk at the center of the Milky Way.

Black holes are typically thought of as consumers rather than producers of energy. Yet their huge gravitational fields can generate power through several theoretical processes. These include the radiation emitted from the accumulation of gas around the hole, the spinning “accretion” disk of matter slowly falling toward the event horizon, the relativistic jets of matter and energy that shoot out along the hole’s axis of rotation, and Hawking radiation—a theoretical way that black holes can lose mass, releasing energy in the process.

From their calculations, Hsiao and colleagues concluded that the accretion disk, surrounding gas, and jets of black holes can all serve as viable energy sources. In fact, the energy from the accretion disk alone of a stellar black hole of 20 solar masses could provide the same amount of power as Dyson spheres around 100,000 stars, the team will report next month in the. Were a supermassive black hole harnessed, the energy it could provide might be 1 million times larger still.

We embrace hybridized practices among different disciplines and living organisms, open knowledge and precarity as a challenge. Our current lines of research are based in the use of sound to understa…

The new study, published in the journal Space Weather, gives precise indicators for how a future mission to Mars should be timed. With sufficient shielding on the Mars-bound spacecraft, a human Mars mission should be shorter than four years to keep the astronauts safe, the study says.

The Sun can also protect future Mars astronauts from the worst radiation.

Back in August of 2017, Cassini stared at Enceladus for 14 hours, looking at the moon’s night side.

Below is a movie sequence of images, garnered from the final dedicated observation of the Enceladus’ geysers by the imitable Cassini spacecraft.

Back in August of 2,017 Cassini stared at Enceladus for 14 hours, looking at the moon’s night side. The movie begins with a view of the part of the surface lit by reflected light from Saturn and transitions to completely unilluminated terrain. About halfway through the sequence, the exposure time of the images changes in order to make fainter features more visible as the light level drops.

Quantum Computing Platform Accelerates Transition from Bulk Optics to Integrated Photonics on a Silicon Chip Smaller Than a Penny

The quantum computing market is projected to reach $65 billion by 2,030 a hot topic for investors and scientists alike because of its potential to solve incomprehensibly complex problems.

Drug discovery is one example. To understand drug interactions, a pharmaceutical company might want to simulate the interaction of two molecules. The challenge is that each molecule is composed of a few hundred atoms, and scientists must model all the ways in which these atoms might array themselves when their respective molecules are introduced. The number of possible configurations is infinite—more than the number of atoms in the entire universe. Only a quantum computer can represent, much less solve, such an expansive, dynamic data problem.

Scientists had their hands full making sense of this one.

Summary: Researchers have discovered a new molecule that could increase the ultra-fast decision-making capabilities of computers. The simple molecule provides a new electronic circuit element in which complex logic is encoded in nanoscale material properties.

An international team of scientists including researchers at University of Limerick in Ireland has discovered a new molecule that could further increase ultra-fast decision making in computers.

Of the more than 55,000 jobs, Jassy announced, over 40,000 will be in the United States, while others will be in countries such as India, Germany and Japan via its job fair ‘Amazon Career Day.’ In order to learn about Amazon job opportunities, click on their job page: amazon.jobs/in.

Amazon Career Day is a free event on September 16 2021 at 10:00am IST. “This interactive experience is for all job seekers, regardless of your level of experience, professional field, or background – whether you are interested in working at Amazon or elsewhere,” the company said in. a statement.

Jassy, in his first press interview since he ascended to Amazon’s top post in July, said the company needed more firepower to keep up with demand in retail, the cloud and advertising, among other businesses. He said the company’s new bet to launch satellites into orbit to widen broadband access, called Project Kuiper, would require a lot of new hires, too.
