A $70K salary might look straightforward on paper. But once you factor in employer taxes, statutory benefits, payroll, and country-specific employment costs, that number can skyrocket.

And those costs can vary significantly depending on where your employee is based. So before you build your hiring budget, check out Oyster's Global Hiring Cost Calculator.

The calculator can help you see the full picture by letting you compare employment costs across 120 countries and estimate what a hire could really cost your business. And unlike that new hire, it’s actually 100% free.

Today's dispatches from the frontiers of science carry real weight: Antarctica's most feared glacier is more dangerous than we imagined, a strange signal in the brain may unlock schizophrenia's mysteries, ancient asteroid dust is rewriting solar system history, and a colony of ants is cheerfully ignoring one of biology's fundamental rules. Buckle up.

Antarctica's Thwaites Glacier - already nicknamed the "Doomsday Glacier" for its potential to reshape coastlines worldwide - may contribute twice as much to sea level rise as scientists previously estimated, according to new research. The findings suggest that earlier models significantly underestimated the glacier's instability and the scale of its potential collapse.

Thwaites is one of the largest glaciers on Earth, and its behavior is considered a bellwether for the broader West Antarctic Ice Sheet. If its collapse accelerates, the consequences for coastal cities and low-lying nations could be catastrophic and largely irreversible on human timescales.

This research is a stark reminder that climate projections may be consistently underestimating worst-case scenarios. Policymakers and coastal planners need to incorporate the possibility of far more dramatic sea level rise than current models suggest.

Researchers have identified a mysterious brain signal that appears to be linked to several distinct symptoms of schizophrenia simultaneously. The discovery is significant because schizophrenia has long puzzled scientists with its wide-ranging and seemingly unrelated symptom clusters - from hallucinations and delusions to cognitive difficulties and emotional dysregulation.

Finding a single neural signal that connects multiple symptoms could represent a major step toward understanding the underlying neuroscience of the disorder. Rather than chasing each symptom independently, researchers may be able to target this signal as a unifying mechanism - potentially pointing the way toward more effective treatments.

Schizophrenia affects millions globally and remains one of psychiatry's most challenging conditions. A shared neural root for multiple symptoms could transform how we approach both diagnosis and therapy for this disorder.

Samples collected from asteroid Bennu by NASA's OSIRIS-REx mission are unlocking secrets dating back 4.5 billion years - to the very dawn of our solar system. Scientists studying the pristine material are finding clues about the conditions and chemistry that existed when the Sun and planets were first forming.

Because Bennu is a primitive asteroid, its material has remained relatively unchanged since the early solar system - making it essentially a time capsule. The new findings from these samples are shedding light on processes that are otherwise impossible to observe directly, offering a rare window into planetary formation.

Understanding the chemistry of the early solar system helps scientists piece together how Earth - and potentially life - came to exist. Bennu's secrets may hold answers to some of the deepest questions in planetary science.

A species of ants with remarkably oversized heads has been found to violate a fundamental rule of biology - a rule scientists considered essentially universal across the animal kingdom. The finding is prompting researchers to reconsider how broadly the rule actually applies in nature.

In biology, certain scaling laws govern how body proportions relate to body size. These ants appear to defy those expectations in ways that shouldn't, according to established theory, be possible. Their unusual anatomy suggests that evolutionary pressures - perhaps related to colony defense or food processing - can override constraints once thought to be inviolable.

Every time nature breaks a rule we thought was absolute, it expands our understanding of what life can do. These ants are a vivid reminder that biology's "laws" are really just our best approximations - and evolution loves an exception.

A compelling new hypothesis proposes that Earth's recurring ice ages may have been triggered by a cascading, planet-wide chain reaction in the oceans - a "domino effect" that fundamentally reorganized global heat distribution before sending the planet into a deep freeze.

The research suggests that changes in ocean circulation patterns could have amplified and spread cooling effects across the globe, creating a self-reinforcing cycle. Understanding what kicks off ice ages has been a long-standing puzzle in Earth science, and this ocean-first model offers a new framework for interpreting the geological record.

With today's ocean circulation systems already showing signs of disruption from climate change, understanding how oceanic shifts triggered past global cooling events has urgent modern relevance - even if the direction of change we face today is warming, not cooling.

Astronomers have discovered a mysterious magnetic web hovering above the Sun's surface - a previously undetected structure that could help explain some of the Sun's most puzzling behaviors, including its unpredictable eruptions and the dynamics of its outer atmosphere.

The Sun's magnetic field is notoriously complex, and discovering new structural features above its surface opens fresh avenues for understanding solar weather - the storms of charged particles that can disrupt satellites, power grids, and communication systems here on Earth. The magnetic web may play a role in channeling or storing energy before it's released in solar events.

Better models of solar magnetic behavior could significantly improve our ability to predict dangerous solar storms, giving infrastructure operators - and astronauts - more warning time before harmful space weather arrives.

From the bottom of Earth's glaciers to the outer reaches of our solar system's past - today's science reminds us that the universe is stranger, more connected, and more surprising than we expect. The questions that feel biggest often have answers hiding in the most unexpected places: an ant's oversized head, a rock from a distant asteroid, a signal buried deep in the brain.
