In this quasi-religious programme, ‘working the steps’ is the remedy for any problem, but for me the cracks soon started to showEight of us sat together in a circle in a wooden shed, an outbuilding at a large country house, somewhere in the south of England. The door was ajar, and spring light flooded the room. “Can anyone name any treatment methods for addiction, other than the 12 steps?”...

A study of HIV-positive black and Latino men who have sex with men finds the use of methamphetamine combined with intimate partner violence boosted the activity of genes that regulate the body's inflammatory and antiviral functions. The combination may lead to exhaustion of the immune system in people living with HIV, increasing the risk for developing chronic diseases such as cardiovascular...

Business leaders and management experts often encourage people to speak up in the workplace. Suggesting a creative idea or a more efficient way to work can help companies overcome challenges and meet goals. But new research shows another, more subtle and often overlooked form of speaking up has a big effect on the way work gets done and how teams come together.

Ocean pollution is unfortunately becoming more commonplace, raising concerns over the effect of chemicals that are leaching into the water. In a new study, researchers have discovered how these chemicals can affect the reproduction in common anemonefish Amphiprion ocellaris.

Photons are the basis for many next-generation quantum technologies, including ultra-secure quantum communications and potentially game-changing quantum computers.

Food texture can make the difference between passing on a plate and love at first bite. To date, most studies on food texture center on relating a food's overall composition to its mechanical properties. Our understanding of how microscopic structure and changes in the shape of food affect food texture, however, remains underdeveloped.

For decades, scientists have hotly debated the origin of the western honey bee. Now, new research led by York University has discovered these popular honey-producing bees most likely originated in Asia.

A multi-institutional team of astrophysicists headquartered at Boston University, led by BU astrophysicist Merav Opher, has made a breakthrough discovery in our understanding of the cosmic forces that shape the protective bubble surrounding our solar system—a bubble that shelters life on Earth and is known by space researchers as the heliosphere.

Few developments have rocked the biotechnology world or generated as much buzz as the discovery of CRISPR-Cas systems, a breakthrough in gene editing recognized in 2020 with a Nobel Prize. But these systems that naturally occur in bacteria are limited because they can make only small tweaks to genes. In recent years, scientists discovered a different system in bacteria that might lead to even more...

Three-dimensional fault models are generally more accurate than two-dimensional line models at sending ground shaking alerts to the correct areas as part of an earthquake early warning system, according to a new study.

Unusual ways of investment, such as collecting toys, can generate high returns. For example, secondary market prices of retired LEGO sets grow by 11% annually, which is faster than gold, stocks, and bonds, HSE University economists say. Their paper was published in the Research in International Business and Finance journal.

Researchers have shown that green tea can be used as a reducing reagent for the preparation of nanomaterials to synthesize ammonia. Compared with bulk graphitic carbon nitride, the optimal sample had 2.93-fold photocatalytic nitrate reduction to ammonia activity (2.627 mg/h/gcat), and the NH3 selectivity increased from 50.77% to 77.9%. The team published their approach on September 06 in Energy...

Robots are already in space. From landers on the moon to rovers on Mars and more, robots are the perfect candidates for space exploration: they can bear extreme environments while consistently repeating the same tasks in exactly the same way without tiring. Like robots on Earth, they can accomplish both dangerous and mundane jobs, from space walks to polishing a spacecraft's surface. With space...

A stash of rediscovered dinosaur bones wrapped in century-old newspapers is set to reveal two pasts: one set in the 1920s and the University of Alberta's earliest paleontology, the other some 70 million years ago.

A rare total solar eclipse in Antarctica this weekend (Saturday 4 December) is giving researchers a unique opportunity to learn more about how solar eclipses affect space weather. The next total eclipse in Antarctica will not be until 2039.

Music, dance, art and storytelling have allowed an international team of researchers to reveal aspects of air pollution in Nairobi that would not have been identified otherwise.

An organism's genome could be compared to a complex system of instructions that allows it not only to develop, but also to carry out all the activities essential to its survival. To do this, this genome needs to be expressed correctly, i.e. these instructions need to be "read" properly, and the information it contains must not be altered or degraded over time.

Tropical forests are disappearing at an alarming rate through deforestation, but they also have the potential to regrow naturally on abandoned lands. This has been shown by an international study led by scientists from Wageningen University. How a forest recovers, depends on the amount of rainfall, the age of the forest, and the functional characteristics of the tree species.

In a new study, published in the journal Nature, the researchers show that the planet, which is 31 light years from Earth, is one of the lightest among the nearly 5,000 exoplanets (planets outside our own solar system) that are known today, with half the mass of Earth. It has a diameter of just over 9,000 kilometers—slightly larger than Mars.

Invasive ant species can be found in almost every ecosystem on earth, but the impact these invaders may have on plant health has only recently been investigated by scientists. A new study published in Journal of Ecology is the first of its kind to find that invasive ants can disrupt plants' growth and photosynthesis by nesting at their roots—potentially threatening plants in tropical and...

Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment. They are common: more than about a quarter of all main-sequence stars have debris disks and, since these disks can be hard to detect, it is likely that the fraction is even higher. Current instruments are only able to detect debris disks in systems...
