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.

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.

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.

The first technique capable of measuring the pull of gravity on a particle just microns in diameter could aid the quest for a quantum theory of gravity – a longstanding goal in physics. The new experiment uses a superconducting quantum interference device (SQUID) to detect the force on the particle at ultralow temperatures and suppresses vibrations that might interfere with motion due to gravity.

Gravity differs from the other fundamental forces because it describes a curvature in space-time rather than straightforward interactions between objects. This difference explains, in part, why theoretical physicists have long struggled to reconcile gravity (as described by Einstein’s general theory of relativity) with quantum mechanics. One of the main sticking points is that while the latter assumes space-time is fixed, the former states that it changes in the presence of massive objects. Since experiments to determine which denoscription is correct are extremely difficult to perform, a theory of quantum gravity remains out of reach despite much theoretical effort in areas such as string theory and loop quantum gravity.

Sailing through space might sound like something out of science fiction, but the concept is no longer limited to books or the big screen. In April, a next-generation solar sail technology – known as the Advanced Composite Solar Sail System – will launch aboard Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand. The technology could advance future space travel and expand our understanding of our Sun and solar system.

Solar sails use the pressure of sunlight for propulsion, angling toward or away from the Sun so that photons bounce off the reflective sail to push a spacecraft. This eliminates heavy propulsion systems and could enable longer duration and lower-cost missions. Although mass is reduced, solar sails have been limited by the material and structure of the booms, which act much like a sailboat’s mast. But NASA is about to change the sailing game for the future.

Europe's climate monitor said Tuesday that March was the hottest on record and the tenth straight month of historic heat, with sea surface temperatures also hitting a "shocking" new high.

The magnetic field surrounding the supermassive black hole at the centre of the Milky Way has been observed for the first time. Astronomers using the Event Horizon Telescope (EHT) have been surprised by the orderly nature of the field, which exists in the extremely violent environment surrounding the black hole Sagittarius A*. The study could lead to a better understanding of the crucial role that the magnetic field plays in how the black hole feeds on surrounding matter.

This is the second time that the EHT has observed the magnetic field of a supermassive black hole. In 2021 it detected the field of the black hole at the centre of the galaxy Messier 87 (M87).

Supermassive black holes are believed to be surrounded by plasma that is swirling into the gravitational abyss. This creates a powerful magnetic field, which can then interact with the infalling material. This accelerating material emits copious amounts of radiation including radio waves that are polarized by the local magnetic field.

A fleeting visit of the ESA/JAXA BepiColombo mission to Venus has revealed surprising insights into how gases are stripped away from the upper layers of the planet's atmosphere.

Detections in a previously unexplored region of Venus's magnetic environment show that carbon and oxygen are being accelerated to speeds where they can escape the planet's gravitational pull.

Lina Hadid, CNRS researcher at the Plasma Physics Laboratory (LPP) and lead author of the study said, "This is the first time that positively charged carbon ions have been observed escaping from Venus's atmosphere. These are heavy ions that are usually slow moving, so we are still trying to understand the mechanisms that are at play. It may be that an electrostatic 'wind' is lifting them away from the planet, or they could be accelerated through centrifugal processes."

Once a particle of matter, always a particle of matter. Or not. Thanks to a quirk of quantum physics, four known particles made up of two different quarks—such as the electrically neutral D meson composed of a charm quark and an up antiquark—can spontaneously oscillate into their antimatter partners and vice versa.

At a seminar held March 26 at CERN, the LHCb collaboration at the Large Hadron Collider (LHC) presented the results of its latest search for matter–antimatter asymmetry in the oscillation of the neutral D meson, which, if found, could help shed light on the mysterious matter–antimatter imbalance in the universe.

We're about to find out what's happening with NASA's beleaguered Mars Sample Return mission. In just a few hours – at 17:00 UTC / 13:00 EDT – NASA is going to host a media teleconference that sets out its recommendations for moving forward.

The mission has been ongoing for several years, with the deployment of the Perseverance rover in February 2021. Part of Perseverance's mission is to gather interesting samples of Martian rock to be collected by another mission and returned to Earth.

Last year, the future of the Mars sample return mission became shaky after an independent review determined that the program had "unrealistic budget and schedule expectations", an "unwieldy structure" and was "not arranged to be led effectively".

NASA bit off more than it could chew when it sent the Perseverance rover to Mars to collect samples.

The US$2.4 billion mission landed the rover in Jezero Crater, the site of an ancient lake. It's the ideal spot to search for the fossils of Martian microbes that may have existed when the planet was lush with lakes and rivers.

Perseverance's main mission is to collect samples of the rock and sediment along the lake bed and the crater rim, in hopes of finding a sign that life once thrived on the red planet. The rover has done a fine job – so far it's secured 24 samples – but NASA no longer knows how it's going to bring them to Earth for analysis.

NASA's original design for the retrieval mission, called Mars Sample Return, has fallen apart. The agency is asking companies to step in and propose better ideas.
