Through the looking glass: A cross-chiral reaction challenges our definition of life
Just like your left and right hand exist as mirror images of each other, many biological molecules have their own form of left- and right-handedness, called chirality. Our DNA, for example, is made of right-handed chiral molecules which combine to fo.....»»
Our Universe is not fine-tuned for life, but it’s still kind of OK
Inspired by the Drake equation, researchers optimize a model universe for life. Physicists including Robert H. Dickle and Fred Hoyle have argued that we are living in a universe t.....»»
Ryugu asteroid sample rapidly colonized by terrestrial life despite strict contamination control
Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system. The discovery of extraterrestrial life on asteroids or within meteorites would.....»»
Infrastructure and communication challenges can be barriers to food safety in the low-moisture food industry
Low-moisture foods such as dried fruits, seeds, tree nuts and wheat flour were once considered to carry minimal microbial risks. However, the increased number of outbreaks linked to bacteria-contaminated low-moisture foods has resulted in product rec.....»»
Origin of life research finds RNA can favor both left- and right-handed proteins
The mystery of why life uses molecules with specific orientations has deepened with a discovery that RNA—a key molecule thought to have potentially held the instructions for life before DNA emerged—can favor making the building blocks of proteins.....»»
Scientists uncover cross-species neural mechanism for early detection of life motion in visual processing
Visual systems of both humans and animals can detect life motion from the environment at the earliest stage of visual processing, research by scientists from the Chinese Academy of Sciences (CAS) uncovered......»»
Increasing complexity challenges strategic management, researcher finds
The changes in society and the phenomena surrounding us are becoming more unexpected and interconnected than ever before. This increasing complexity challenges strategic management, making it harder to predict trends and developments. According to a.....»»
R sounds are rough, and L sounds are smooth: Cross-cultural study finds these associations may be universal
People around the world associate a trilled R sound with a rough texture and a jagged shape, and an L sound with a smooth texture and a flat shape, according to the findings of a new study. Researchers believe this association may be more universal t.....»»
Decontaminating toxic tires: Researchers show ability to remove toxic particles from end-of-life tires
Tires are an indispensable part of daily life. Without them, our vehicles would just be a bunch of assembled parts—convenient to sit in, but not effective for getting where you are going......»»
School social workers an underutilized resource as mental health challenges in children sees increase
Youth in America are experiencing a mental health crisis, according to the Centers for Disease Control and Prevention (CDC). The CDC reports that an increasing number of students are experiencing symptoms of hopelessness, depression, and anxiety, alo.....»»
Apple’s best selling iPhone models aren’t what you’d expect, but there’s a good reason
Early in the iPhone’s life, Apple made only one model for everyone. Today, the company releases four flagships every year and also offers the iPhone SE and older models. It’s a lot to keep up with, but a new report gives us a good picture of whic.....»»
Many physicists argue the universe is fine-tuned for life. Our findings question this idea
Physicists have long grappled with the question of why the universe was able to support the evolution of intelligent life. The values of the many forces and particles, represented by some 30 so-called fundamental constants, all seem to line up perfec.....»»
Life in the world"s deepest seas: The challenge of finding 1,000 new marine species by 2030
Oceans cover 71% of the Earth's surface, but despite their immense size and impact on the planet, we know very little about them. While many of us might associate the sea with relaxing holidays on tropical beaches, the ocean is nothing but cold, dark.....»»
Neither desolate nor empty: Deep-sea floor teems with life
The Arctic deep sea harbors significant oil and natural gas reserves along with valuable resources such as rare earths and metals. Climate change and melting ice are facilitating access to these resources, which presents economic opportunities but al.....»»
Invasive zebra mussels are associated with elevated mercury levels in fish, study finds
A study found that invasive zebra mussels significantly alter aquatic ecosystems, and are associated with elevated mercury concentrations in fish. Mercury, a potent neurotoxin, poses a serious threat to both aquatic life and human health......»»
Nanofibers made of copper-binding peptides disrupt cancer cells
While toxic in high concentrations, copper is essential to life as a trace element. Many tumors require significantly more copper than healthy cells for growth—a possible new point of attack for cancer treatment......»»
Advancements in genomic research reveal alternative transcription initiation sites in thousands of soybean genes
Rosalind Franklin, James Watson and Francis Crick discovered the structure of DNA—that molecular blueprint for life—over 70 years ago. Today, scientists are still uncovering new ways to read it......»»
Cross-IdP impersonation bypasses SSO protections
Cross-IdP impersonation – a technique that enables attackers to hijack the single sign-on (SSO) process to gain unauthorized access to downstream software-as-a-service (SaaS) applications without compromising a company’s primary identity.....»»
Could Ocean Engineering Pull Carbon from the Atmosphere as a Last Resort against Climate Change?
Changing the ocean’s chemical and biological makeup could force it to pull vast amounts of planet-warming carbon from the atmosphere. But is that a line we want to cross?.....»»
Hornetsecurity DMARC Manager protects against fraud and phishing attacks
Hornetsecurity launched DMARC Manager, an advanced tool addresses the complex challenges organisations face in managing DMARC, DKIM, and SPF configurations, especially for those operating across multiple domains. As email threats such as fraud and im.....»»
Hollywood techniques help NASA visualize supercomputing data
Captivating images and videos can bring data to life. NASA's Scientific Visualization Studio (SVS) produces visualizations, animations, and images to help scientists tell stories of their research and make science more approachable and engaging......»»
