Fearsome tyrannosaurs were social animals, study shows

|

The fearsome tyrannosaur dinosaurs that ruled the northern hemisphere during the Late Cretaceous period (66-100 million years ago) may not have been solitary predators as popularly envisioned, but social carnivores similar to wolves, according to a new study. The finding, … Read More

Analysis of famous fossil helps unlock when humans and apes diverged

|

A long-awaited, high-tech analysis of the upper body of famed fossil “Little Foot” opens a window to a pivotal period when human ancestors diverged from apes, new USC research shows. Little Foot’s shoulder assembly proved key to interpreting an early … Read More

NASA’s Ingenuity Mars Helicopter succeeds in historic first flight

|

Monday, NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The Ingenuity team at the agency’s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from … Read More

Tarantula’s ubiquity traced back to the Cretaceous

|

Tarantulas are among the most notorious spiders, due in part to their size, vibrant colors and prevalence throughout the world. But one thing most people don’t know is that tarantulas are homebodies. Females and their young rarely leave their burrows … Read More

COVID-19: Scientists identify human genes that fight infection

|

Scientists at Sanford Burnham Prebys have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers’ understanding of factors that affect disease severity and … Read More

Hidden magma pools pose eruption risks that we can’t yet detect

|

Volcanologists’ ability to estimate eruption risks is largely reliant on knowing where pools of magma are stored, deep in the Earth’s crust. But what happens if the magma can’t be spotted? Shane Rooyakkers, a postdoctoral scholar at GNS Science in … Read More

A new super-Earth detected orbiting a red dwarf star

|

In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses … Read More

New CRISPR technology offers unrivaled control of epigenetic inheritance

|

Scientists have figured out how to modify CRISPR’s basic architecture to extend its reach beyond the genome and into what’s known as the epigenome — proteins and small molecules that latch onto DNA and control when and where genes are … Read More

Scientists generate human-monkey chimeric embryos

|

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time — up to 20 days. The research, despite its ethical concerns, has … Read More

How many T. rexes were there? Billions: Analysis of what’s known about the dinosaur leads to conclusion there were 2.5 billion over time

|

That’s a question Charles Marshall pestered his paleontologist colleagues with for years until he finally teamed up with his students to find an answer. What the team found, to be published this week in the journal Science, is that about … Read More

Entanglement-based quantum network

|

A team of researchers from QuTech in the Netherlands reports realization of the first multi-node quantum network, connecting three quantum processors. In addition, they achieved a proof-of-principle demonstration of key quantum network protocols. Their findings mark an important milestone towards … Read More

Coral reefs prevent more than $5.3 billion in potential flood damage for U.S. property owners, study finds

|

Coral reefs provide many services to coastal communities, including critical protection from flood damage. A new study led by researchers at the University of California, Santa Cruz, and the U.S. Geological Survey reveals how valuable coral reefs are in protecting … Read More

Telescopes unite in unprecedented observations of famous black hole

|

In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told. Data from 19 observatories … Read More

Joyful screams perceived more strongly than screams of fear or anger

|

The human scream signals more than fear of imminent danger or entanglement in social conflicts. Screaming can also express joy or excitement. For the first time, researchers have demonstrated that non-alarming screams are even perceived and processed by the brain … Read More

Elusive particle may point to undiscovered physics

|

The muon is a tiny particle, but it has the giant potential to upend our understanding of the subatomic world and reveal an undiscovered type of fundamental physics. That possibility is looking more and more likely, according to the initial … Read More

Plastic planet: Tracking pervasive microplastics across the globe

|

Really big systems, like ocean currents and weather, work on really big scales. And so too does your plastic waste, according to new research from Janice Brahney from the Department of Watershed Sciences. The plastic straw you discarded in 1980 … Read More
