This single study has cracked open an entirely new field of scientific research, which Hadany calls phytoacoustics.

Veits wants to know more about the underlying mechanisms behind the phenomenon the research team observed. For instance, what molecular or mechanical processes are driving the vibration and nectar response? She also hopes the work will affirm the idea that it doesn’t always take a traditional sense organ to perceive the world.

“Some people may think, How can [plants] hear or smell?” Veits says. “I’d like people to understand that hearing is not only for ears.”

Perovskite solar cells (PSCs) are promising solar technologies. Although low-cost wet processing has shown advantages in small-area PSC fabrication, the preparation of uniform charge transport layers with thickness of several nanometers from solution for meter-sized large area products is still challenging.

Recently, a research group led by Prof. LIU Shengzhong from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has developed a facile surface redox engineering (SRE) strategy for vacuum-deposited NiO x to match the slot-die-coated perovskite, and fabricated high-performance large-area perovskite submodules.

This work was published in Joule (“Surface redox engineering of vacuum-deposited NiO x for top-performance perovskite solar cells and modules”).

UK police urges users to switch on two-factor authentication.

A database containing 5.4m Twitter users’ data is reportedly for sale on a popular criminal forum. Twitter is investigating the issue, which the seller said exploited a vulnerability in its systems reported in January.

The seller, using the nickname ‘devil,’ advertised the data on the Breached Forums site and demanded at least $30,000 for it. They said that the database contains the phone numbers and email addresses of users, including celebrities and companies.

The hack reportedly exploits a vulnerability first reported by a HackerOne user known as ‘zhirinovskiy.’ That bug enabled “an attacker with a basic knowledge of scripting/coding” to find a Twitter user’s phone number and email address, even if the user has hidden them in privacy settings. The attacker explained how to exploit the bug in their HackerOne report. Twitter acknowledged the bug and fixed it five days later.

As the amount of data stored in devices and shared over the internet continuously increases, computer scientists worldwide are trying to devise new approaches to secure communications and protect sensitive information. Some of the most well-established and valuable approaches are cryptographic techniques, which essentially encrypt (i.e., transform) data and texts exchanged between two or more parties, so that only senders and receivers can view it in its original form.

Physical unclonable functions (PUFs), devices that exploit “random imperfections” unavoidably introduced during the manufacturing of devices to give physical entities unique “fingerprints” (i.e., trust anchors). In recent years, these devices have proved to be particularly valuable for creating cryptographic keys, which are instantly erased as soon as they are used.

Researchers at Peking University and Jihua Laboratory have recently introduced a new system to generate cryptographic primitives, consisting of two identical PUFs based on aligned carbon nanotube (CNT) arrays. This system, introduced in a paper published in Nature Electronics, could help to secure communications more reliably, overcoming some of the vulnerabilities of previously proposed PUF devices.

New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field. Swirling liquid iron in the Earth’s outer core, located approximately 1,800 miles beneath our feet, generates our planet’s protective magnetic field, called the magn.

New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field.

Swirling liquid iron in the Earth’s outer core, located approximately 1,800 miles beneath our feet, generates our planet’s protective magnetic field, called the magnetosphere. Although this magnetic field is invisible, it is vital for life on Earth’s surface. That’s because the magnetosphere shields the planet from solar wind—streams of radiation from the sun.

However, about 565 million years ago, the magnetic field’s strength dropped to 10 percent of its strength today. Then, mysteriously, the magnetic field bounced back, regaining its strength just before the Cambrian explosion of multicellular life on Earth.

Why do some individuals always seem to be healthy while other people often get viruses and bacteria? Despite sleeping close to their sick partner every night, how can a sick person’s spouse avoid contracting their illness? During the COVID-19.

First identified in 2019 in Wuhan, China, Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has spread globally, resulting in the 2019–20 coronavirus pandemic.
