How to gently caress atoms

Researchers at TU Wien develop a method to study metal oxide surfaces using a single oxygen atom attached to an atomic force microscope tip, allowing for gentle examination of surface structures without altering the atoms. The technique reveals different ways oxygen molecules attach to titanium atoms on the surface.

Giving GDP a needed ecological companion

A new measure, Gross Ecosystem Product (GEP), is proposed to value nature's contributions to economic activity and human well-being. GEP summarizes the economic value of nature's services, highlighting the need to balance domestic and ecosystem needs for a sustainable future.

NHGRI researchers uncover genes linked to common recurrent fever in children

NHGRI researchers have identified genetic mutations associated with PFAPA syndrome, a periodic fever disorder that affects only children. The study reveals commonalities with other inflammatory conditions, including Behçet's disease and canker sores, and highlights the potential for new treatments and diagnostic tools.

New light for plants

Researchers at ITMO University have created glass-ceramic lamps that produce a wider spectrum of light, including infrared, to improve plant growth in greenhouses. The lamps use chrome and glass-ceramics to emit both red and IR light, offering new possibilities for agricultural facilities.

How much color do we really see?

Researchers found that most people's color awareness is limited to a small area around the dead center of their visual field. The brain likely fills-in much of our perceptual experience when color is removed from the periphery, with nearly a third of observers not noticing desaturated areas.

Systemic lupus erythematosus (SLE)

The BLISS-LN study showed that belimumab added to standard therapy resulted in a significantly better primary renal response at 2 years, with 43% showing improvement versus 32% on placebo. Additionally, patients treated with belimumab had a 50% lower risk of experiencing renal events associated with poor prognosis.

Great white shark diet surprises scientists

A new study reveals that great white sharks spend most of their time foraging just above the seabed, contrary to the common stereotype of a shark's dorsal fin above the surface. The diet of juvenile white sharks consists mainly of fish species that live on or near the seafloor.

Jodrell Bank leads international effort which reveals 157 day cycle in unusual cosmic radio bursts

A four-year study at Jodrell Bank Observatory reveals a repeating Fast Radio Burst (FRB) follows a cyclic pattern with radio bursts observed every 90 days, followed by a silent period of 67 days, repeating every 157 days. This discovery provides an important clue to identifying the origin of FRBs.

Fewer antibiotics to better fight bacterial infections

A multicentre study involving over 500 patients found that a shorter treatment duration, reduced to half the standard 14-day course, was equally effective in treating bacteraemia. The researchers also identified certain risk factors, including older age and pathogen type, which can influence the effectiveness of antibiotic treatment.

Dreaming with purpose

Adult-born neurons in the hippocampus play a crucial role in memory consolidation during REM sleep, according to a study published in Neuron. The researchers found that activity in these neurons is necessary for memory consolidation and that synaptic changes occur during learning, enabling memory formation.
