Phys.org media bias and reliability
AllSides and Ad Fontes Media place Phys.org in the centre. We have seen it on 52 published stories of ours.
The short answers
Is Phys.org biased?
AllSides and Ad Fontes Media place Phys.org in the centre. An outlet rating describes a broad pattern in its output, not every article it publishes.
Is Phys.org left or right?
AllSides and Ad Fontes Media place Phys.org in the centre. In the three-way grouping used on story pages, that puts it under Centre.
Is Phys.org reliable?
The factual-reliability assessments we hold for Phys.org are Ad Fontes Media: Very high factuality; Media Bias/Fact Check: High factuality. These are outlet-level assessments, not a guarantee that every report is correct.
What Phys.org has been covering
Our account of each story, written from every outlet that ran it, with Phys.org’s own report linked underneath.
A study analyzing satellite data from 2002 to 2022 indicates the Great Pacific Garbage Patch has become bluer and greener. Researchers suggest microplastic pollution is a likely cause, though further direct measurements are needed for definitive proof.

Archaeologists have uncovered evidence in a Siberian tomb suggesting cannabis was used for psychoactive purposes at least 2,800 years ago. This finding potentially predates similar documented use in China by 300 years, though some experts express skepticism.

Scientists have detected evidence of volcanism on Mars, with some suggesting an inactive magma chamber may exist beneath the surface. Hydrogen chloride emissions are attributed to hot magma, and the rate of volcanic eruptions has declined significantly over billions of years.

Physicists at CERN's Large Hadron Collider have detected evidence of a rare beauty particle decay into two muons. The LHCb experiment's finding, with a statistical significance of 3.2 sigma, is a step towards confirming a process predicted to occur once in ten billion decays, a search that has been ongoing for over 40 years.

White truffle harvests in Italy and Croatia are being affected by prolonged heat and drought. This has resulted in smaller yields, lower quality truffles, and a significant increase in prices compared to the previous year.

At Canada's first youth-led climate trial, Dr. Elizabeth Pinsky testified that children are disproportionately vulnerable to climate change. She cited immature thermoregulatory systems, higher relative air intake, and psychological harms like eco-anxiety.

A nearly two-pound meteorite discovered in Mali in 2022 has been identified as a 4.1-billion-year-old piece of Mars. Named Teghaza 001, it offers new insights into the Red Planet's early history and water cycle.

A new Lancet report indicates 710,000 heat-related deaths occurred globally in 2023, with over 70% attributed to human-caused climate change. Researchers are urging a formal declaration of a global health emergency to address accelerating climate harms.

A UN report synthesising 154 countries' climate pledges indicates a 6% reduction in global greenhouse gas emissions by 2035. This figure is only a tenth of the approximately 60% cut scientists recommend to limit warming to 1.5°C.

Colorado's most prominent glaciers experienced dramatic thinning in 2026, losing ice at double the rate of the previous five years. Record low snowpack and high temperatures contributed to the accelerated melt, raising concerns about water sources and mountain hazards.

A new study suggests US drinking water may contain twice the reported levels of PFAS, also known as 'forever chemicals'. Researchers used computer models to analyze EPA data, finding current reporting methods capture only 44% of average concentrations for 25 PFAS chemicals.

More than 50,000 people are estimated to have died across European cities during this summer's heat waves. A new analysis attributes about two-thirds of these deaths directly to climate change, driven by fossil fuel pollution, making it the region's deadliest heat summer on record.

A UN report states that global warming will inevitably surpass 1.5 degrees Celsius above pre-industrial levels. Current policies project a rise to 2.8 degrees by 2100, but immediate, significant emissions reductions could limit the peak and return temperatures to 1.5C by 2100.

A United Nations report indicates humanity is heading for a hotter world than previously projected, partly due to increased emissions from the United States. If countries meet their reduction pledges, the Earth will likely warm by 2.2 degrees Fahrenheit (1.2 degrees Celsius).

A planet described as a gas giant has been discovered orbiting a white dwarf star approximately 250 light-years away. This 'second-generation' planet is believed to have formed from material expelled by its dying star, offering new insights into planet formation.

An international team of scientists has reported that seven of the 16 tracked climate indicators have reached record extremes. The rate of global warming has accelerated significantly, and atmospheric carbon dioxide levels are at their highest in two million years, according to the study published in BioScience.

A new dinosaur species, Invictibellatrix amberina, has been identified from a fossil found on the Isle of Wight. The long-clawed predator, which lived 120 million years ago, is the first evidence of megaraptorans in Europe and may have viewed humans as prey.

The Thwaites Glacier in West Antarctica is melting at an accelerated rate, according to new research published in Nature Communications. Scientists warn this could significantly increase its contribution to global sea level rise, with potential consequences for coastal communities worldwide.

Six people have died from the combined effects of Hurricane Simon and the remnants of Tropical Storm Rachel along Mexico's Pacific coast. Flooding and landslides caused by the storms have also left five people missing and damaged homes and infrastructure.

Who says so
2 organisations have published a rating for this outlet, in their own words. Where they disagree, the disagreement is the useful part and it is left standing.
How reliably it reports fact
A rating of the newsroom in general, by others, and a different thing from the Trust score we publish on each story, which judges one piece of reporting.
Very high factuality
Who owns it
We hold no ownership record for Phys.org.
Where it publishes from
What we have seen ourselves
Counted across the stories this site has published, which is the only denominator a reader can check: every one of them has a page, and every page lists the reports it was written from.
- Stories

- Reports listed
- 52
- We could read

43 of those reports were paywalled or blocked to us. Our reading of this outlet is built on the 9 we could open, not on everything it published.
A blindspot is measured against one side of the spectrum. Phys.org is rated centre, so there is no side for it to be counted against and we publish no figure here.
Across the 52 stories of ours where at least three of the reports we listed carried a time, we logged no report earlier than Phys.org’s on 2 of them. Overall it filed a median of 19 hours after the earliest report we logged.
Measured 6 November 2026. Last seen in a coverage list 6 November 2026. Ratings pulled 7 October 2026.
Other outlets rated the same way
Publishers carrying the same published leaning as Phys.org, also publishing from United Kingdom, ordered by how often we have seen them on a story. Sharing a rating is not the same as being alike.
Think this page is wrong?
The leanings above are published by AllSides, Ad Fontes Media and Media Bias/Fact Check, and we republish them rather than make them. If you think one is misapplied, the strongest place to say so is with the organisation that made it, and every verdict here links to their page.
What we are responsible for is everything else: the ownership chain, where Phys.org publishes from, which of our stories we have listed it on, and whether we have the right publisher at all. Tell us what is wrong and an editor reads it.
Report something wrong on this page
Anything we correct is written up in the public corrections log. We do not publish reader votes as a rating, because an unattributed rating is the thing this site exists to argue against.
Every rating on this page is a named third party’s published work, republished with its author and, where one exists, a link to it. Our own coverage record is the section we measure ourselves. Neither is a judgement of any individual report: those are scored story by story, and the reasoning is on our methodology page.
