In a study of the worm C. elegans, the team found bacteria species linked to the development of the conditions, and others that can counteract the effect.
Researcher Professor Johann de Bono said: ‘There’s a lot of evidence that prostate cancer causes what we call immune tolerance — that the cancer suppresses the body from attacking it with its immune cells.
Scientists have discovered that a key protein may be the secret to treating prostate cancer patients with ‘miracle’ immunotherapy drugs.
Clinical trials have now begun – with the goal of unleashing cancer-killing white blood cells to attack the tumour.

On May 6, 2021 NASA published 4K UHD image from Ingenuity Mars Helicopter’s onboard camera and video footage during flight at Airfield B. Successful 4th flight on Mars for 133 meters distance by Ingenuity happened on April 30. New Ingenuity’s location called Airfield B. Previous location is Wright Brothers Field. The helicopter climbing to an altitude of 16 feet (5 meters) before flying south approximately 436 feet (133 meters) and then back, for an 872-foot (266-meter) round trip. In total, we were in the air for 117 seconds. NASA’s Ingenuity Mars Helicopter’s fourth flight path is superimposed here atop terrain imaged by the HiRISE camera aboard the agency’s Mars Reconnaissance Orbiter. NASA’s Ingenuity Mars Helicopter took 4K color image during its fourth flight. “Airfield B,” its new landing site, can be seen below. The helicopter will seek to set down there on its fifth flight attempt to 10 meters altitude on May 7th.

The story of the “Forest Keeper” of India.
They say it’s impossible for one person to change the world… However, the hero of our story decided to prove everyone wrong. As he believes, the main thing is to know exactly what you want from life and pursue your goal with dedication. Then you’ll be bound to succeed…
A team of researchers from Zhejiang University, Xi’an Jiaotong University and Monash University has developed a way to bind multiple strands of graphene oxide into a thick cable. In their paper published in the journal Science, the group describes their process and possible uses for it. Rodolfo Cruz-Silva and Ana Laura Elías with Shinshu University and Binghamton University have published a Perspectives piece in the same issue outlining the work by the researchers and explaining why they believe the technique could prove useful in manufacturing efforts.
In recent years, materials scientists have been exploring the possibility of making products using total or partial self-assembly as a way to produce them faster or at less cost. In biological systems where two materials self-assemble into a third material, scientists describe this as a fusion process, borrowing terminology from physics. So when a single material spontaneously separates into two or more other materials, they refer to it as a fission process. In this new effort, the researchers have developed a technique for creating graphene-oxide-based yarn that exploits both processes.
The work by the team is very basic. They created multiple strands of graphene oxide and then dunked them into a solvent solution for 10 minutes. When the strands were pulled from the solution, they banded together forming a cord, or single strand of yarn. They also developed a means for reversing the process—dunking the strand of yarn in a different solvent solution.

Two new approaches allow deep neural networks to solve entire families of partial differential equations, making it easier to model complicated systems and to do so orders of magnitude faster.
“I think both with the how the workers have been treated and how the community has really been kicked aside here with the creeks, one of the problems we’re seeing is Wall Street values being applied to rural, working class communities,” said Smith. “That’s the values of ‘money first,’ and ‘consequences don’t matter.’”.
It’s sunny and in the mid-70s in Tuscaloosa County, Alabama right now. Normally, that would be prime conditions for a swim in Davis Creek or Texas Creek. But right now, both are running black, full of thick wastewater runoff.
Although nothing in the laws of quantum physics limits such quantum weirdness to subatomic particles, the theory predicts that at much larger scales — say, the size of a cat — quantum effects should be so vanishingly small as to be unobservable in practice. Physicists have long debated whether this is just a limitation of our senses and instruments, or whether macroscopic objects are governed by their own set of laws that is fundamentally different from quantum mechanics. To explore this question, researchers have been pushing to observe quantum effects at ever larger scales. “One point of our research is, is there quantum in the classical world?” says Mika Sillanpää, a physicist at Aalto University in Finland.
Quantum drums
In an experiment at the US National Institute of Standards and Technology in Boulder, Colorado, physicist Shlomi Kotler and his collaborators built a pair of vibrating aluminium membranes akin to two tiny drums, each around 10 micrometres long.
Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen.
But a key step in that process, known as the oxygen evolution reaction or OER, has proven to be a bottleneck. Today it’s only about 75% efficient, and the precious metal catalysts used to accelerate the reaction, like platinum and iridium, are rare and expensive.
Now an international team led by scientists at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory has developed a suite of advanced tools to break through this bottleneck and improve other energy-related processes, such as finding ways to make lithium-ion batteries charge faster. The research team described their work in Nature today.
Implantable electronics are among the most promising healthcare technologies, as they can help to remotely monitor specific biological processes associated with a patient’s health. While researchers have developed a variety of implantable devices over the past decade or so, existing technologies have several limitations that can prevent their widespread use in clinical settings.
The first factor preventing the large-scale implementation of existing implantable technologies is the structural mismatch between these devices and most organs/tissues in the body, which typically have complex 1D or 3D structures. Secondly, reliably fixing soft electronic devices on organs that are moving or pulsating has so far proved to be highly challenging.
Researchers at Daegu-Gyeongbuk Institute of Science & Technology (DGIST) in South Korea and ETH Zürich have recently developed a new fiber-based strain-sensing device that could overcome the limitations of existing implantable electronics. This sensor, presented in a paper published in Nature Electronics, comprises a capacitive fiber strain sensor with an inductive coil for wireless readout.
