Our earlier science and technology stories — artificial intelligence, biology, physics, computing and more — all in one place.
Can Darkness Move Faster Than Light?
Researchers at Technion confirmed a 50-year-old prediction: dark vortices inside light waves can hit superluminal speeds — and it doesn't break Einstein's rules.
Apr 29 Science & ResearchAncient DNA Study Shows Human Evolution Is Still Accelerating
A Harvard study of 16,000 ancient genomes found that natural selection sped up after farming began — and is reshaping genes tied to diabetes, immunity, and more.
Apr 28 Medicine & HealthAspirin Cuts Colon Cancer Recurrence by Half — In the Right Patients
A landmark trial of 3,500 patients found daily aspirin slashed colon cancer recurrence by nearly 50% — but only in patients with a specific genetic mutation.
Apr 27 Health & WellnessWalking 7,000 Steps a Day Could Lower Your Cancer Risk
A major NIH and Oxford study of 85,000 adults found daily walking — even light activity like chores — can cut cancer risk by up to 26%. Here's what that means for you.
Apr 26 Science & Research120,000-Year-Old Human Footprints Found in a Saudi Desert
Seven ancient footprints in a dried Saudi lake bed could be the oldest proof of Homo sapiens outside Africa — and they're rewriting human migration history.
Apr 26 Opinion & AnalysisWhy Are 90% of Humans Right-Handed? An Evolutionary Biologist Explains
Nine out of ten humans favour the same hand — and it's not a coincidence. Science is finally explaining why right-handedness took over our species, and what it cost.
Apr 25 Medicine & HealthIbogaine for Depression: What RFK Jr. Said vs. What Science Shows
RFK Jr. called ibogaine the most promising depression treatment ever. Johns Hopkins researchers disagree. Here's what the science actually says about this risky psychedelic.
Apr 25 Biology & Life SciencesAI Found Hidden Physics Laws in the Fourth State of Matter
An AI model trained on dusty plasma data corrected decades-old physics assumptions — with over 99% accuracy. Here's what scientists at Emory University actually found.
Apr 23 Biology & Life SciencesScientists Can Now Deliver Healthy Mitochondria to Dying Cells
A Swiss lab built MitoCatch — a system that guides healthy mitochondria directly into damaged cells. It rescued neurons from a rare blindness disease. Here's what that means.
Apr 23 Health & WellnessMalaria Forced Early Humans to Flee — And Shaped Who We Are Today
A new study reveals malaria steered human settlement for 74,000 years in Africa, fragmenting populations and rewiring the genetic map of our species.
Apr 22 Physics & MaterialsScientists Used a Giant X-Ray Laser to Watch Plasma Heat Up in Real Time
A team fired a trillion-photon X-ray laser at a copper wire and watched the plasma heat and ionize — all in under 3 picoseconds. Here's what they found.
Apr 21 Medicine & HealthYour Chocolate's Flavor Depends on a Hidden Amazon Secret
Scientists in Brazil found that choosing the right cocoa clone — before fermentation even begins — can dramatically change the nutrition and flavor of your chocolate.
Apr 21 Climate TechnologyHumans Are Changing the Planet — And Always Have Been
A new study argues the Anthropocene crisis started thousands of years ago — and that human ambition, not fear, is the only force big enough to fix it.
Apr 20 Medicine & HealthA Year of Exercise Lowered Stress Hormones — But Not How You'd Expect
A 12-month clinical trial found aerobic exercise cut hair cortisol — a deep marker of chronic stress — even when other heart risk factors barely moved.
Apr 20 Climate TechnologyGreenland's Ice Vanished 7,000 Years Ago — And It Could Happen Again
Scientists drilled 509 metres into Greenland ice and found the ground beneath was open sky just 7,100 years ago. Here's why that number should worry everyone.
Apr 19 Biology & Life SciencesTexas Horned Lizard Sperm Frozen for First Time — A Lifeline for a Threatened Species
Scientists successfully froze Texas horned lizard sperm for the first time. Post-thaw motility hit 38% — enough to bank genetics for a species vanishing from the wild.
Apr 18 Physics & MaterialsTime May Not Actually Flow — Here's What Philosophers Really Think
Physics says past, present and future all exist equally. Philosophy asks why we feel otherwise. The answer to both questions is stranger than you think.
Apr 18 Computing & QuantumQuantum Encryption Just Sent a Secret Key 120 km — Using a Single Atom of Light
Scientists in Germany cracked a long-standing barrier in quantum communication: secure key distribution over 120 km using a single-photon quantum dot — running stably for 6 hours straight.
Apr 17 Gadgets & DevicesSamsung Galaxy Tab S11 Review: Is It Worth ₹87,999 in India?
Samsung's Tab S11 packs a Dimensity 9400+, Galaxy AI, and 7 years of updates — but at ₹87,999, should Indian buyers choose it over the iPad? Here's the real picture.
Apr 17 Medicine & HealthYour Mouthwash Might Be Making Things Worse. This New Toothpaste Is Different.
Most mouthwashes kill everything — good bacteria included. Then the bad bugs grow back faster. A new toothpaste from German researchers blocks only the harmful ones. No collateral damage.
Apr 17 Biology & Life SciencesAre You a Boltzmann Brain? Physics Can't Rule It Out
A rigorous new analysis shows your memories could be a random cosmic fluctuation — and the second law of thermodynamics is no defense. Here's why.
