While cellular networks and Wi-Fi systems are more advanced than ever, they are also quickly reaching their bandwidth limits. Scientists know that in the near future they'll need to transition to much higher communication frequencies than what current systems rely on, but before that can happen there are a number of—quite literal—obstacles standing in the way. Researchers from Brown University and Rice University say they've advanced one step closer to getting around these solid obstacles, like walls, furniture and even people—and they do it by curving light. In a new study published in Communications Engineering, the researchers describe how they are helping address one of the biggest logjams emerging in wireless communication.

There is currently no treatment to slow or halt Parkinson's disease. Available drugs don't slow disease progression and can treat only certain symptoms. Medications that work early in the disease, however, such as Levodopa, generally become ineffective over the years, necessitating increased doses that can lead to disabling side effects. Without understanding the fundamental molecular cause of Parkinson's, it's improbable that researchers will be able to develop a medication to stop the disease from steadily worsening in patients. Many factors may contribute to the development of Parkinson's, both environmental and genetic. Until recently, underlying genetic causes of the disease were unknown. Most cases of Parkinson's aren't inherited but sporadic, and early studies suggested a genetic basis was improbable. Nevertheless, everything in biology has a genetic foundation. As a geneticist and molecular neuroscientist, I have devoted my career to predicting and preventing Parkinson's disease. In our newly published research, my team and I discovered a new genetic variant linked to Parkinson's that sheds light on the evolutionary origin of multiple forms of familial parkinsonism, opening doors to better understand and treat the disease.

Here's a closeup of the bright prominence that many people reported seeing with their naked eye during the eclipse. This was captured using two telescopes- at 2000mm and at 3650mm. These prominences are part of the solar chromosphere, and normally require a specially modified telescope to view. Not during an eclipse! 🌐 AJamesMcCarthy

NASA Administrator Bill Nelson and Japan’s Minister of Education, Culture, Sports, Science and Technology (MEXT) Masahito Moriyama have signed an agreement to advance sustainable human exploration of the Moon. Japan will design, develop, and operate a pressurized rover for crewed and uncrewed exploration on the Moon. NASA will provide the launch and delivery of the rover to the Moon as well as two opportunities for Japanese astronauts to travel to the lunar surface.

An experimental and controversial stem cell transplant, which aims to treat traumatic spinal cord injury, has shown promising new results in a phase I clinical trial. Not only was the single-dose spinal injection safe and well-tolerated by all 10 patients with paralysis, it also resulted in some improved movement and sensation for 7 volunteers. While that's seriously hopeful, the type and degree of injury seems to matter. Researchers at the Mayo Clinic in the US admit that in all likelihood, only about five percent of patients with a complete injury to their thoracic spine would regain any feeling or movement with this therapy, based on their results. Nevertheless, neurosurgeon Mohamad Bydon says: "In spinal cord injury, even a mild improvement can make a significant difference in that patient's quality of life."

When humans get involved in places they weren’t invited, things start to change. The Moon is no different. A team of researchers at the University of Kansas believes that human involvement—including the more than 100 spacecraft interactions we have had with our natural satellite over the past 64 years—makes us one of the most dominant forces shaping the Moon. That’s enough, they believe, to declare a new epoch on the Moon—the “Lunar Anthropocene.”

At the Centre for Chronobiology of the University of Basel, [Dr Christine] investigates the effects of light on humans and is the first author of a study investigating the effects of different light colors on the internal clock and sleep. The team of researchers from the University of Basel and the TUM has now published its findings in the journal Nature Human Behaviour. Night mode on screens—useful or not? We often hear that the short-wavelength component of light from smartphone and tablet screens affects biological rhythms and sleep. The recommendation is therefore to put your mobile phone away early in the evening or at least use the night shift mode, which reduces the short-wavelength light proportions and looks slightly yellowish. Dr. Blume confirms this. However, the yellowish color adjustment is a by-product that could be avoided. "Technologically, it is possible to reduce the short-wavelength proportions even without color adjustment of the display; however, this has not yet been implemented in commercial mobile phone displays," says the sleep researcher.

Recently, NASA's Curiosity rover achieved a momentous accomplishment by marking 4,000 Martian days since its touchdown on the Red Planet in 2012. In the last two decades, NASA has sent five robotic vehicles – rovers to Mars, according to the space agency. Sojourner was the initial rover to explore the celestial planet, succeeded by Spirit and Opportunity, Curiosity, and Perseverance.

When streams of ultra-fast protons collide, a Higgs boson might pop into existence for the briefest instant before decaying into lighter particles. In that moment, physicists can work backwards to estimate the mass of what could be the most important and yet most elusive particle in the Standard Model. Having crunched the numbers on a mind-boggling number of proton collisions using the Large Hadron Collider (LHC), physicists now have the most precise figure yet for this all-important property.

"The bright, steady gamma-ray glow of the Milky Way is punctuated by intense, days-long flares of near-light-speed jets powered by supermassive black holes in the cores of distant galaxies," said Seth Digel, a senior staff scientist at SLAC National Accelerator Laboratory in Menlo Park, California, who created the images. "These dramatic eruptions, which can appear anywhere in the sky, occurred millions to billions of years ago, and their light is just reaching Fermi as we watch." Gamma rays are the highest-energy form of light. The movie shows the intensity of gamma rays with energies above 200 million electron volts detected by Fermi's Large Area Telescope (LAT) between August 2008 and August 2022. For comparison, visible light has energies between 2 and 3 electron volts. Brighter colors mark the locations of more intense gamma-ray sources.

"These results indicate the potential for an easy and novel method for early detection of autism and development coordination disorder," said senior author Lisa Aziz-Zadeh, a professor at the USC Mrs. T.H. Chan Division of Occupational Science and Occupational Therapy. "This is especially important as motor signatures appear early in autism—usually before social symptoms. And this methodology does not involve potential biasing by the assessor." "Early identification allows for tailored therapeutic approaches, which result in better long-term developmental outcomes," said first author Christiana Dodd Butera, a postdoctoral fellow at USC Chan. "Having the appropriate therapy for the appropriate child at the most impactful time in development would be the long-term goal of this detection work."

A UNIGE team shows that the human brain is capable of identifying the vocalizations of certain primate species, if they are close to us and if the frequencies used are also close to our own. Are we able to differentiate between the vocal emissions of certain primates? A team from the University of Geneva (UNIGE) asked volunteers to categorize the vocalizations of three species of great apes (Hominidae) and humans. During each exposure to these "onomatopoeia," brain activity was measured...
