Despite their popularity in the science fiction genre, there is much to be learned about black holes. Researchers have proposed a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts.

A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans — but no other known animal species.

Three Thai orchids have been found to rely on a wide range of fungi to help them take carbon out of the soil instead of producing their own organic carbon.

Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. However, a newly adapted low-dose technique called adaptive statistical iterative reconstruction may enable radiologists to reduce patient radiation resulting from CT up to 65 percent, according to a new study.

Scientists have developed new methods in which an entire bacterial genome was cloned in a yeast cell by adding yeast centromeric plasmid sequence to the bacterial chromosome and modified it in yeast using yeast genetic systems. This modified bacterial chromosome was then isolated from yeast and transplanted into a related species of bacteria to create [...]

A group of researchers in Australia and Taiwan has developed a new way to analyze the health of human teeth using lasers. By measuring how the surface of a tooth responds to laser-generated ultrasound, they can evaluate the mineral content of tooth enamel — the semi-translucent outer layer of a tooth that protects the underlying [...]

Honeybees in colonies affected by colony collapse disorder (CCD) have higher levels of pathogens and are co-infected with a greater number of pathogens than their non-CCD counterparts, but no individual pathogen can be singled out as the cause of CCD, according to a study by an international team of researchers.

Pain therapy for cancer patients — whether inpatient or outpatient — is often inadequate. At Heidelberg University Hospital, the use of an innovative electronic system — combined with guidance by an experienced clinical pharmacist — has been successfully tested. The treatment of the patients showed little variance from international guidelines on pain therapy. In addition, [...]
