Plants appear to detect the patter of falling rain
MIT engineers have found the first direct evidence that plant seeds can sense sounds in nature: Rice submerged in shallow water germinated 30% to 40% more quickly when exposed to vibrations from water dripping on the surface. They think other types of seeds may respond similarly.

The Pentagon Is Looking Into the Dialog Data Exposure for Unmasking National Security Offi
Exposed records from the private group included the personal information of a senior White House intelligence official and an active-duty special operations officer.
Another massive data breach exposed millions of driver’s license numbers
Another massive data breach exposed millions of driver’s license numbers
The cyberattack targeting a U.S. insurance giant is the largest known breach of driver's license numbers so far in 2026.
US cybersecurity agency CISA had to build its incident playbook during the incident, agenc
Independent cybersecurity journalist Brian Krebs reported in May that a security researcher with cyber firm GitGuardian alerted him to reams of exposed passwords stored in a publicly accessible GitHub repository, which an employee of a CISA contractor had uploaded.
'Ragebait' culture on social media exposed in new study
A new study has revealed how social media creators are turning anger into entertainment, and what that means for public debate. Research by Dr. Nicholas John from the University of Manchester and Dr. CJ Reynolds from the University of Copenhagen has explored the rise of "ragebait
Loss of DNA protector gene exposes vulnerabilities in cancerous cells
Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this process fails or if key genes are mutated.
Climate change will raise the risk of severe heat waves: New Zealand homes aren't ready
Climate change will raise the risk of severe heat waves: New Zealand homes aren't ready
Europe's summer heat wave has exposed tens of millions of people to temperatures above 35°C, broken records and claimed hundreds of lives. Early climate attribution studies suggest Europe's event would have been "virtually impossible" just 50 years ago without human-caused climat
Bumblebees exposed to up to 7 times as much toxic metal as honeybees
Bumblebees collect up to seven times the amount of toxic heavy metals as honeybees even when foraging in the same environment, new research from the University of Cambridge has found. Exposure to these metals can affect everything from their ability to forage for food to their ab
Evidence of elusive high-energy gravitons in quantum Hall systems
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are confined to a ve
Study explores social media's role in tornado disaster communication
Study explores social media's role in tornado disaster communication
When a powerful EF-4 tornado tore through Rolling Fork, Mississippi, on March 24, 2023, social media became a critical tool for sharing weather warnings, damage reports and recovery information. But a new study from University of Nebraska–Lincoln media scholar Cory Armstrong foun
Harmful ozone may have reached two-thirds of EU residents during record June heat wave
Two-thirds of the European Union's population may have been exposed to harmful levels of ozone pollution during last month's record-breaking heat wave, a report exclusively shared with AFP warned Thursday.
New imaging method reveals how electric fields reshape ferroelectric materials
New imaging method reveals how electric fields reshape ferroelectric materials
New research is shedding light on longstanding debates over the behavior of ferroelectric materials when those materials are exposed to electric fields. The findings stem from the use of a novel technique that allows researchers to observe the real-time behavior of domain walls i
