Can we truly assess whether someone finds us attractive? Cognitive psychologist Iliana Samara conducted her Ph.D. project on romantic attraction and discovered that men, in particular, tend to overestimate the interest of their date. She explains why this may be.

The interaction of solids with high-intensity ultra-short laser pulses has enabled major technological breakthroughs over the past half-century. On the one hand, laser ablation of solids offers micromachining and miniaturization of elements in medical or telecommunication devices. On the other hand, accelerated ion beams from solids using intense lasers may pave the way for new opportunities for cancer treatment with laser-based proton therapy, fusion energy research, and analysis of cultural heritage.

A young whale's journey across the Mediterranean highlights the many threats facing ocean animals, researchers say.

Despite their formidable bodies, male gorillas are lacking in one particular area of their anatomy.

Having more education has long been linked to better individual health. But those benefits are also contagious, say the co-authors of a new working paper.

Primordial black holes (PBHs) have recently received much attention in the physics community. One of the primary reasons is the potential link to dark matter. In effect, if PBHs can be proven to exist, there's a very good chance that they are what dark matter, the invisible thing that makes up 85% of the universe's mass, is made of. If proven, that would surely be a Nobel-level discovery in astrophysics.

Food fraud concerning the geographical origin of hazelnuts intended for consumption is a problem that damages the agri-food sector and generates economic losses and consumer distrust.

Are anti-misinformation interventions on social media working as intended? It depends, according to a new study led by William & Mary researchers and published in the Proceedings of the CHI Conference on Human Factors in Computing Systems (CHI '24).

As climate change warms Philadelphia, the plants that can be grown in the city will change, too.

In March, Target became the latest mega-retailer to offer "free" delivery—for a price. For $99 a year, subscribers to Target Circle 360 can place unlimited orders without having to worry about shipping costs. Target competes with similar plans offered by Walmart and Amazon.

Advanced information processing technologies offer greener telecommunications and strong data security for millions, a study led by University of Maryland (UMD) researchers revealed.

Since the inception of microcomb, whose generation relies on Kerr nonlinearity in microresonator, the coherent soliton state has attracted intense research. Although the operation of sub-comb outputs is straightforward, as a noncoherent comb state, it was often overlooked in previous techniques.

Engineers at MIT, Nanytang Technological University, and several companies have developed a compact and inexpensive technology for detecting and measuring lead concentrations in water, potentially enabling a significant advance in tackling this persistent global health issue.

The first and the best-known metallocene is "ferrocene," which contains a single iron atom. Today, sandwich complexes can be found in many inorganic chemistry textbooks, and the bonding and electronic structure of metallocenes is taught in undergraduate chemistry lecture courses. Sandwich molecules also play an important role in industry, where they are used as catalysts and in the synthesis of special metallopolymers.

A new global study from IOP Publishing (IOPP) has found that certain peer review communities continue to feel overburdened by reviewer requests, while others remain underrepresented.

Researchers have developed new optical tweezers that can stably trap particles that are large—about 0.1 mm—and irregularly shaped. While conventional optical tweezers use highly focused laser beams to trap micro- or nano-scale rod shaped or spherical particles, the advance could expand light-based trapping to a wider range of objects such as groups of cells, bacteria and microplastics.

Research by Royal Holloway, University of London and ZSL has found that a critically endangered bird's biggest threat is being taken from its habitat to be used as a caged bird for its beauty.

Studies show that South Africa is one of only three countries in the world where religious participation has increased in recent years. The other two countries are Italy and the US.

Media psychologists at the University of Cologne have studied how students' individual needs, conceptions and reasons relate to cheating behavior in online exams.

Pesticides threaten humans, wildlife and our environment. Food production must change.

In the popular imagination, the Caribbean is paradise, an exotic place to escape to. But behind the images of balmy beaches and lush hotel grounds lies a crisis, the likes of which its residents have never experienced.

Seventy-eight percent of people in England and Wales think that crime has gone up in the last few years, according to the latest survey. But the data on actual crime shows the exact opposite.

The world literally stopped during the COVID-19 pandemic. But while countries locked down to keep coronavirus at bay, wildlife traffickers carried on their illegal activities. Global risk governance and criminology academics Annette Hübschle and Meredith Gore studied the traffickers' methods and share lessons from their resilience.

Children today are growing up surrounded by technology. So it's easy to assume they will be able to write effectively using a keyboard.

A new technique for 3D printing medication has enabled the printing of multiple drugs in a single tablet, paving the way for personalized pills that can deliver timed doses.
