Ham radio operators receive signals from Voyager 1 on Dwingeloo telescope
We have used the historic Dwingeloo radio telescope to receive signals from the Voyager 1 spacecraft. Only a few telescopes in the world have received these signals, which are very faint due to the distance of Voyager 1: almost 25 billion kilometers, more than four times the distance to Pluto.

School smartphone ban results in better sleep and improved mood: study
Psychologists at the University of York, who tested the impact that smartphones have on children’s behaviour for a new two-part documentary series for Channel 4, found that a ban in school impacted positively on sleep and mood.

Researchers discover new third class of magnetism
A new class of magnetism called altermagnetism has been imaged for the first time in a new study. The findings could lead to the development of new magnetic memory devices with the potential to increase operation speeds of up to a thousand times.

Noninvasive imaging method can penetrate deeper into living tissue
MIT researchers developed a non-invasive imaging technique that enables laser light to penetrate deeper into living tissue, capturing sharper images of cells. This could help clinical biologists study disease progression and develop new medicines.

Study reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction of large ice age mammals.

Fructose in diet enhances tumor growth: research
Fructose is a sweetener added to ultra-processed foods, typically in the form of high-fructose corn syrup. WashU research shows that the liver turns fructose into lipids that many types of cancers crave.

The largest open-source dataset of car designs, including their aerodynamics
DrivAerNet++, the largest open-source dataset for car aerodynamics developed to date, can be used to quickly train an AI model to generate novel car designs. This process could potentially lead to more fuel-efficient cars and electric vehicles with longer range.

Nearly half of teenagers globally cannot read with comprehension
The chart shows the share of children at the end of lower-secondary school age — aged 12 to 15 — who meet the minimum proficiency set by UNESCO in reading comprehension. This means they can connect the main ideas across various texts, understand the author’s intentions, and draw reasoned conclusions.

Solar-powered desalination system requires no extra batteries
MIT engineers built a solar-powered desalination system that produces large quantities of clean water despite variations in sunlight throughout the day. Because it requires no extra batteries, it offers a much more affordable way to produce drinking water, compared to other solar-driven designs.

Humans have caused 1.5 °C of long-term global warming according to new estimates
A new study published today in Nature Geoscience by Dr Andrew Jarvis at Lancaster University and Professor Piers Forster at the University of Leeds shows that humans may have already caused 1.5 °C of global warming when measured from a time genuinely before the industrial revolution and the start of large-scale carbon…
