Measuring the mass of W bosons took 10 years – and the result was not what physicists expected. PM Images/Digital Vision via Getty Images

A decade of science and trillions of collisions show the W boson is more massive than expected – a physicist on the team explains what it means for the Standard Model

A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Permafrost and ice wedges have built up over millennia in the Arctic. When they thaw, they destabilize the surrounding landscape. Michael Robinson Chavez/The Washington Post via Getty Images

Thawing permafrost is roiling the Arctic landscape, driven by a hidden world of changes beneath the surface as the climate warms

Ground is collapsing and massive lakes are draining in a matter of days. Thawing permafrost is having profound effects on the region and its infrastructure.
New research indicates that rhesus monkeys show interoception – the ability to sense physiological processes like their own heartbeats. Matthew Verdolivo/UC Davis IET Academic Technology Services

Monkeys can sense their own heartbeats, an ability tied to mental health, consciousness and memory in humans

Researchers used a test designed for babies to show that rhesus monkeys can sense their own heartbeats. The finding opens up important paths of research into consciousness and mental health issues.
Cloud services that aren’t properly managed can ‘leak’ data into the wrong hands. id-work/DigitalVision Vectors via Getty Images

Mismanaged cloud services put user data at risk

Cloud services are convenient, but if an organization isn’t careful about how it uses them, the services can also give data thieves an opening.

Fishing, strip clubs and golf: How male-focused networking in medicine blocks female colleagues from top jobs

By surveying over 100 people in academic medicine, a researcher found that women are consistently excluded from important networking activities like watching sports, drinking at bars and playing golf.
There are even more types of viruses in the ocean than researchers once thought. newannyart/iStock via Getty Images Plus

Researchers identified over 5,500 new viruses in the ocean, including a missing link in viral evolution

Viruses do more than just cause disease – they also influence ecosystems and the processes that shape the planet. Tracing their evolution could help researchers better understand how viruses work.
From thalidomide to Viagra, drug repurposing salvaged failed treatments by giving them new targets. smartboy10/DigitalVision Vectors via Getty Images

Repurposing generic drugs can reduce time and cost to develop new treatments – but low profitability remains a barrier

Drug repurposing can redeem failed treatments and squeeze out new uses from others. But many pharmaceutical companies are hesitant to retool existing drugs without a high return on investment.

How Ukraine has defended itself against cyberattacks – lessons for the US

Russian hackers have been attacking Ukraine for years, but with help from US government agencies, businesses and universities, Ukraine’s cyber defenses have grown stronger.

Cyberattacks have yet to play a significant role in Russia’s battlefield operations in Ukraine – cyberwarfare experts explain the likely reasons

Cyberattacks can be devastating, just not on the battlefield, according to researchers who looked at 10 years of armed conflicts around the world.

Nuclear fusion hit a milestone thanks to better reactor walls – this engineering advance is building toward reactors of the future

In January 2022, the JET fusion experiment produced more power over a longer period of time than any past attempt. Two physicists explain the engineering advancements that made the result possible.
