Beam me to the stars: Scientists propose wild new interstellar travel tech

If we are ever going to be go beyond the solar system, to share the miracle of Earth Life, it’s clear that we will need radical new ways of getting there.

One such solution that was recently proposed uses electron beams accelerated to near the speed of light to propel spacecraft, something that could overcome the vast distances between Earth and the next closest star. “For interstellar flight, the primary challenge is that the distances are so great,” Greason explained. “Alpha Centauri is 4.3 light-years away; about 2,000 times further away from the sun than the Voyager 1 spacecraft has reached — the furthest spacecraft we’ve ever sent into deep space so far. No one is likely to fund a scientific mission that takes much longer than 30 years to return the data — that means we need to fly fast.”

A study by Greason and Gerrit Bruhaug, a physicist at Los Alamos National Laboratory, published in the journal Acta Astronautica, highlights that reaching practical interstellar speeds hinges on the ability to deliver sufficient amounts of kinetic energy to the spacecraft in an economic way.

“Interstellar flight requires us to collect and control vast amounts of energy to achieve speeds fast enough to be useful,” said Greason. “Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from […] swinging by the sun for a boost, just don’t have the ability to scale to useful interstellar speeds.”

Where Biology Meets Resonance: Light, Vibration, and Living Order

When we think about biology, we usually picture chemistry: molecules bumping into each other, enzymes reacting, and signals spreading by diffusion. That picture is real—but it may be incomplete. In my recent paper in Harmonic Science Perspectives (Vol 1, Issue 1), I propose a complementary layer of cellular organization: a fast, coordination-capable “resonance network” that uses three interchangeable carriers of energy and information.

Introduction A simple picture: three messengers that can translate into one another Where this shows up in the body: mitochondria and microtubules as a coupled network Why interconversion matters: translation is the key feature Resonant synchronization: a possible mechanism for cellular timing Therapeutic implications: why light and sound therapies might work better together A note on what’s established vs what’s proposed Conclusion: a new lens on living organization

Those three carriers are light (photons), vibration/sound-like mechanical waves (phonons), and mobile electronic excitations in biomolecules (excitons). The central idea is simple to state even if the details are deep: living systems may continuously convert energy back and forth between these three modes to synchronize activity across space and time inside the cell—and potentially across tissues.

The Color of Wonder and the Chemical Code of Creation

This essay is adapted from Traversal.

We look at a thing — a bird, a ball, a planet — and perceive it to be a certain color. But what we are really seeing is the color that does not inhere in it—the portion of the spectrum it shirks, the wavelength of light it reflects back unabsorbed. Our world appears a swirling miracle of blue, but its blueness is only a perceptual phenomenon arising from how our particular atmosphere, with its particular chemistry and its insentient stubbornness toward a particular portion of the spectrum, absorbs and reflects light.

In the living world beneath this atmosphere that scatters the shorter wavelengths as they pass, blue is the rarest color: There is no naturally occurring true blue pigment among living creatures. In consequence, only a slender portion of plants bloom in blue, and an even more negligible number of animals are bedecked with it, all having to perform various tricks with chemistry and the physics of light, some having evolved astonishing triumphs of structural geometry and optics to render themselves blue. Each feather of the blue jay is tessellated with tiny light-reflecting beads arranged to cancel out every wavelength of light except the blue.

‘Lock-and-key’ chemistry keeps cancer drugs inactive until they reach tumor sites

Many therapeutic molecules used in cancer treatments are highly toxic, often harming healthy tissues and causing significant side effects. This creates a critical need for strategies that localize their toxic activity to tumors. What if cancer drugs could stay dormant until they reach cancer cells? A new study by Syracuse University researchers demonstrates a promising chemistry-based strategy that could do just that.

Xiaoran Hu, assistant professor of chemistry in the College of Arts & Sciences (A&S), and his team introduced a prototyping “lock-and-key” system that holds therapeutic drugs in an inactive, caged form until a separate chemical trigger releases them at a specific site. The study was published in Angewandte Chemie International Edition. It introduces a new platform to control when and where chemical bonds break inside living systems.

“We are developing a broadly applicable tool that has the potential to regulate the activity of different types of therapeutics,” Hu says. “Think of this as a tool, like a hammer, that could be used on different nails.”

Mapping ADHD Heterogeneity and Biotypes by Topological Deviations in Morphometric Similarity Networks

Normative modeling of morphometric similarity networks in ADHD identified three distinct biotypes with unique clinical-neural profiles, supporting more neurobiologically informed stratification for ADHD management.

Question Can normative modeling of topological properties derived from brain morphometric similarity networks yield robust stratification biomarkers for pediatric populations with attention-deficit/hyperactivity disorder (ADHD)?

Findings This multisite case-control study included 1,154 participants, characterizing ADHD heterogeneity through hub-centric topological deviations derived from morphometric similarity networks. Three distinct biotypes emerged, each exhibiting unique clinical-neural profiles with characteristic neurochemical and functional correlates, validated in an independent transdiagnostic cohort of 554 ADHD cases.

Meaning The integration of normative modeling with heterogeneity through discriminative analysis (HYDRA) clustering yielded both dimensional and categorical insights into ADHD heterogeneity, thereby enhancing our understanding of the ADHD’s neurobiological complexity.

A new eco-friendly water battery could theoretically last for centuries

The problem with many types of modern batteries is that they rely on harsh chemicals to work. Not only can these corrosive liquids damage internal parts over time, but they can also leach into soil and water when disposed of, contaminating it. But researchers from the City University of Hong Kong and Southern University of Science and Technology have developed an alternative, a new kind of eco-friendly battery that runs on a solution similar to the minerals used in tofu brine.

The team describes their work in a paper published in the journal Nature Communications.

The scientists replaced traditional acids and alkalis with neutral salts of magnesium and calcium to create the electrolyte. These are the same minerals used as brine in tofu production. Keeping this liquid at a neutral pH of 7.0 prevents the type of corrosive reactions that can destroy a battery from the inside out.

Chemists thought phosphorus had shown all its cards—until it surprised them with a new move

A discovery by UCLA organic chemists may one day put catalytic converter thieves out of business. In new research, they’ve used abundant, inexpensive phosphorus as a catalyst in chemical reactions that usually require precious metals like platinum, one of the metals targeted in theft of the automotive components that convert chemicals in vehicle exhaust into less harmful forms.

This advance, however, will likely be more useful in the pharmaceutical industry and could one day help bring down the price of some drugs.

Jupiter’s Moons May Have Held Life’s Ingredients at Birth

Dr. Olivier Mousis: “Our findings suggest that Jupiter’s moons did not form as chemically pristine worlds. Instead, they may have accreted, or accumulated, a significant inventory of COMs at birth, providing a chemical foundation that could later interact with the liquid water in their interiors.” [ https://www.labroots.com/trending/space/30236/jupiter-s-moon…ts-birth-2](https://www.labroots.com/trending/space/30236/jupiter-s-moon…ts-birth-2)

When did Jupiter’s Galilean moons first contain the ingredients for life? This is what complementary studies published in The Planetary Science Journal and Monthly Notices of the Royal Astronomical Society hopes to address as an international team of scientists investigated potential timescales for when three of Jupiter’s Galilean moons, Io, Europa, Ganymede, and Callisto, could have first formed the ingredients for life. This study has the potential to help scientists better understand the formation and evolution of the Galilean moons and what this could mean in the search for life beyond Earth.

For the studies, the researchers explored the formation of complex organic molecules (COMs) within Jupiter’s original disk of gas, dust, and ice, also called the circumplanetary disk, along with modeling how COMs could be delivered to the Jupiter system from the protoplanetary disk that formed the Sun and planets. They examined how interaction with ultraviolet radiation from the Sun could influence COM formation. The overarching goal of both studies was to ascertain both how and when Jupiter’s Galilean moons received the ingredients for life, specifically focusing on icy grains that currently comprise Europa, Ganymede, and Callisto.

In the end, the researchers found that icy grains could have obtained COMs and delivered them to Jupiter’s moons both within Jupiter’s circumplanetary disk and from the solar system’s protoplanetary disk. Additionally, the models showed that approximately half of the simulated icy grains could have formed within the solar system’s protoplanetary disk and were delivered to Jupiter’s moons. Finally, the researchers estimated these processes occurred billions of years ago during the early formation of the solar system.

New lab technique can reverse chemical process linked with Alzheimer’s disease

An Oregon State University scientist and a team of undergraduate students have uncovered real-time insights into a chemical process linked with Alzheimer’s disease, paving the way toward better drug designs. The researchers used a molecule measuring technique to observe in a laboratory setting how certain metals can promote the protein clumping that leads to the blocked neural pathways associated with Alzheimer’s. Led by Marilyn Rampersad Mackiewicz, associate professor of chemistry in the OSU College of Science, the research team also watched molecules known as chelators disrupt or reverse the clumping. The findings are published in ACS Omega.

Alzheimer’s disease is the most common form of dementia, a chronic condition of impaired cognitive function that affects large numbers of older adults and their loved ones. According to the Centers for Disease Control and Prevention, Alzheimer’s is the sixth-leading cause of death for people age 65 and older.

In Alzheimer’s patients, aggregations of amyloid-beta proteins interrupt brain cells’ ability to communicate with each other. The brain needs certain metals to work properly, but problems arise when the metals are present in unbalanced quantities.

FDA Greenlights Life Biosciences’ Human Study, Setting Up Pivotal Test for Aging Theory from Harvard’s David Sinclair

…Life Biosciences, a biotech company co-founded by Sinclair, received the FDA’s approval to begin a human trial testing its gene therapy based on the Information Theory of Aging. The gene therapy is designed to rewind the clock and restore the function of dying cells…

…Life Biosciences’ gene therapy has been under development for quite a while. In the 1990s, David Sinclair first contended that the deterioration and loss of epigenetic information—chemical tagging patterns on DNA that regulate which genes are turned on and off—plays an important role in driving aging. Sinclair subsequently dubbed this contention the Information Theory of Aging. Fast forward to the present day, and Life Biosciences has produced a gene therapy that delivers three proteins, which Sinclair’s laboratory helped establish, to reset epigenetic information to a more youthful state.

‘It’s extremely exciting,’ Sinclair told Endpoints News. ‘It’s been over 30 years to get to this point, and we’re about to learn if all of that work is going to come to fruition this year.’

The FDA has greenlighted Life Biosciences’ first human trial testing whether their gene therapy can confer a near-total rejuvenating reset of cells.
