Discovery of the Week

The brain's hibernation switch has been found — Scientists have finally located the brain circuit that controls hibernation, a discovery in hamsters that points toward inducing a hibernation-like state in mammals that don't naturally do it. Hibernation is a deep, energy-saving state in which body temperature and metabolism plummet. That raises the possibility of one day putting non-hibernating mammals — including humans — into a similar protective state. _Significance: High._ (Science Magazine News)

Space Missions & Astronomy

Roman Space Telescope is go for launch — NASA's Nancy Grace Roman Space Telescope is set to lift off Sunday at 7:26 a.m. EDT on a SpaceX Falcon Heavy, carrying a wide-field camera that will capture Hubble-quality images across a patch of sky 100 times larger than Hubble can see. The observatory will hunt exoplanets, map dark matter — the invisible substance holding galaxies together — and probe dark energy, the mysterious force accelerating the universe's expansion. _Significance: High._ (New Scientist, NASA News)

Warm anomaly found deep beneath Mars — Using tidal tomography, a technique that images a planet's interior from how it flexes under gravitational tugs, researchers detected an area of unusual heat beneath the boundary between Mars's southern highlands and northern lowlands. That boundary, known as the crustal dichotomy, is one of the Red Planet's oldest and most puzzling features. _Significance: Medium._ (Nature News)

Get ready for the 'eclipse of the century' — A new guide details where and when to watch the total solar eclipse of Aug. 2, 2027, expected to be the longest such eclipse until 2114. _Significance: Medium._ (New Scientist)

Life Sciences & Medicine

Football's brain-disease toll — and the diagnosis gap — A startling new study suggests at least one in four former NFL players develops CTE, a degenerative brain disease caused by repeated head impacts, yet doctors still can't diagnose it in living athletes; it can only be confirmed after death. The finding sharpens the debate over how to protect players from a condition that remains invisible until too late. _Significance: High._ (Science Magazine News)

Bat genomes reveal secrets of long life and virus tolerance — Sequencing the genomes of Myotis bats, a group known for unusually long lifespans for its size, offers new insights into how these animals live long and tolerate viruses without falling ill. _Significance: Medium._ (Nature News)

Two genetic codes now run in the same cell — Researchers have gotten two different genetic codes to operate simultaneously inside living cells, a trick that could make it easier to engineer cells that produce drugs and novel materials. _Significance: Medium._ (Ars Technica Science)

Orbital drug and tissue manufacturing moves closer — Maturing techniques for working in microgravity (near-weightlessness), combined with cheaper launch costs, are pushing research toward manufacturing pharmaceuticals and biological tissues in space. _Significance: Medium._ (Science Magazine News)

Physics & Materials

Nuclear waste could power spacecraft of the future — Researchers are exploring whether radioactive waste from reactors can be repurposed as fuel for space missions, potentially turning a disposal problem into an energy source for deep-space probes. _Significance: Medium._ (Nature News)

A layperson's guide to Hilbert space — Quanta Magazine tours Hilbert space, the abstract, infinite-dimensional mathematical realm in which all quantum states live, and explains why working in it lets physicists make accurate predictions that defy everyday intuition. _Significance: Low._ (Quanta Magazine)

Climate & Earth Science

Corals show climate change is strengthening El Niño — A 1,000-year coral archive from the Galápagos Islands shows El Niño events have grown stronger over the past 40 years, in line with rising global temperatures. El Niño is the periodic warming of the tropical Pacific that disrupts weather worldwide, so more powerful events could mean worse floods, droughts and heat waves. _Significance: High._ (New Scientist, Science Magazine News)

Burying underpants to map soil health — In a global citizen-science project, more than a thousand volunteers buried organic cotton underpants and later dug them up to see how quickly they decomposed; the results show land use is the biggest factor in decomposition rates. The study helps scientists understand how farming and other land management affect the living soil beneath our feet. _Significance: Medium._ (Ars Technica Science)

Technology-Driven Science

Ultrafast, reference-free gene discovery in single cells — A new computational method rapidly identifies genetic sequences in data from individual cells without needing a reference genome to compare against, which could speed up studies of rare cell types and disease. _Significance: Medium._ (Nature News)
