Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. In a new study, the researchers have traced back the dichotomy in the angular momentum of spiral and elliptical galaxies to their different formation history. In particular, the low angular momentum of ellipticals is mainly originated by nature in the central regions during the early galaxy formation process.

A silicone heart has been developed that beats almost like a human heart. Researchers have now tested how well it works.

The scientific textbook depiction of the flu virus is about to get a facelift, due to a new discovery that a model of the influenza genome architecture untouched since the 1970s isn't so perfect after all. The finding could give scientists the opportunity to better predict pandemics and find new ways to disrupt the flu virus.

Researchers were able to positively influence the immune response in severe viral and bacterial co-infection. Using a human lung tissue model, they were able to show that the immune mechanisms triggered by viral pathogens prevent the tissue from mounting an effective response against a simultaneously occurring bacterial infection.

A bacterial enzyme enables reactions opens up alternatives to key industrial chemical processes, explain scientists in a new report.

The first data network for research into Huntington's disease has been created by an international team, now freely available to all scientists in this field.

Squirrels can remember problem-solving techniques for long periods and can apply them to new situations, researchers have discovered.

Babies with hearing loss who are diagnosed by three months and receive interventions by six months have broader vocabularies than those treated later, a new study found. It also found that nearly half don't meet early intervention guidelines.

A new software system helps robots to more effectively act on instructions from people, who by nature give commands that range from simple and straightforward to those that are more complex and imply a myriad of subtasks.

A new paper describes the application of machine learning to avoiding plasma disruptions, which will be crucial to ensuring the longevity of future large tokamaks, say researchers.

Large, robust, lens-shaped microfossils from the approximately 3.4 billion-year-old Kromberg Formation of the Kaapvaal Craton in eastern South Africa are not only among the oldest elaborate microorganisms known, but are also related to other intricate microfossils of the same age found in the Pilbara Craton of Australia, according to an international team of scientists.

By the age of one, infants already prefer speakers of their native tongue, but do not necessarily view speakers of an unfamiliar language negatively, according to new research. The findings suggest that, while positivity toward familiar groups may be innate, dislike for unfamiliar groups appears to be a learned behavior.

A new class of mediators, or biochemical triggers, has been discovered that researchers have named elovanoids (ELVs). This discovery provides the first evidence of the existence of elovanoids and of their significant role in protecting and sustaining retinal pigment epithelial (RPE) and photoreceptor cell survival.

A team of researchers studied the biofilm construction capabilities of nontypeable Haemophilus influenzae (NTHI), a bacterium responsible for sinusitis, pneumonia, exacerbations of cystic fibrosis and COPD, bronchitis and ear infections.

Daily tomato consumption appeared to cut the development of skin cancer tumors by half in a mouse study, report investigators.
