Science News: Recent scientific discoveries and expert analysis

A slowly spinning universe could resolve a puzzle in physics known as the Hubble tension, a new model suggests.

Using an experimental technique called "Oz," researchers stimulated the human retina such that people saw a brand-new color.

Measles can erase the immune system's "memory" and cause a rare but fatal health condition. The MMR vaccine prevents these repercussions, evidence shows.

As climate change melts ice sheets and glaciers, water is being redistributed across the globe — and could end up moving the point of Earth's axis of rotation.

A graduate student accidentally created a blend of oil, water and nickel particles that formed an unexpected shape.

People experience different amounts of pain during IUD insertion, but there are a number of pain-relief options available to patients getting the contraceptive.

Researchers conducted the first-ever near-infrared analysis of an extragalactic recurrent nova and found it is one of the hottest nova explosions ever discovered.

A rare 'smiley face' triple conjunction is coming to Earth's morning skies on April 25, when Venus, Saturn and the crescent moon form a celestial smirk near the horizon.

A reanalysis of ancient DNA shows that a major cultural change took place in Ireland after four centuries of farming.

About half of the non-dark matter in the universe cannot be accounted for by stars and galaxies alone. Now, scientists say previously undetected clouds of hydrogen gas could finally reveal it.

The drugmaker Lilly announced topline results of a clinical trial of a new pill in the same drug class as injectables like Ozempic.

Samples drilled by the Curiosity rover on Mars have revealed abundant signs of a carbon cycle that remained hidden from orbital scans, alongside clues of how life may have been wiped out on the planet.

The rete ovarii, a poorly understood structure connected to the ovaries, may be much more essential to ovarian function than scientists initially thought.

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming decades. But some experts are skeptical.

Roughly 20 "shooting stars" per hour may be visible during the peak of the Lyrid meteor shower overnight on Monday, April 21-22.

The land beneath the former Aral Sea in Kazakhstan and Uzbekistan is rising and will continue to do so for many decades. Now, scientists have an explanation that involves the sea drying up.

Scientists have discovered evidence of large quantities of biosignature chemicals — only known to be made by life on Earth — on an exoplanet more than 100 light-years away. It could be the most promising sign yet of alien life.

The exotic quantum phase, predicted over half a century ago, could lead to advances in quantum computing, sensors and communication technology.

Human skeletons from a large stone tomb may help archaeologists understand a mysterious pre-Inca population in Peru.

A 7,500-year-old antler unearthed in Sweden had characteristic breakage patterns that suggest it was the handle for a battle ax.
