Scientists reported on the prevalence of multiple agents capable of causing human disease that are present in three species of ticks in Long Island.

Major physical changes occurred in the human heart as people shifted from hunting and foraging to farming and modern life. As a result, human hearts are now less 'ape-like' and better suited to endurance types of activity.

Early rice growers unwittingly gave barnyard grass a big hand, helping to give root to a rice imitator that is now considered one of the world's worst agricultural weeds.

Bicuspid aortic valve (BAV), the most common heart valve birth defect, is associated with genetic variation in human primary cilia during heart valve development, report researchers. Crucial to cilia development is the exocyst, which shuttles cilia cargo to…

Are you willing to ride in a driverless car? Researchers studied how Americans' perceived cost of commute time changes depending on who's driving.

Technological advances are allowing commercial fishing fleets to double their fishing power every 35 years and put even more pressure on dwindling fish stocks, new research has found.

A drug used to treat enlarged prostate may also slow the progression of Parkinson's disease, according to a new study.

Semiconductors -- and our mastery of them -- have enabled us to develop the technology that underpins our modern society. These devices are responsible for a wide range of electronics, including circuit boards, computer chips and sensors.

Researchers have engineered a plasmid to remove an antibiotic resistance gene from the Enterococcus faecalis bacterium, an accomplishment that could lead to new methods for combating antibiotic resistance.

New research shows just how important positive childhood experiences are for long-term health, especially for those who experience significant adversity as a child. Studies over the past 20 years have found a correlation between adverse childhood events (such…

A research team has developed a novel sample holder that considerably facilitates the preparation of protein crystals for structural analysis. New research shows how proteins in solution can be crystallized directly onto the new sample holders themselves, then…

Mosquitoes are more likely to acquire the dengue virus when they feed on blood with low levels of iron, researchers report. Supplementing people's diets with iron in places where both iron deficiency anemia and dengue fever are a problem could potentially…

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior. The results suggest that a larger amount of the Earth's…

Corn, soybean, and cotton farmers shudder at the thought of Palmer amaranth invading their fields. The aggressive cousin of waterhemp - itself a formidable adversary - grows extremely rapidly, produces hundreds of thousands of seeds per plant, and is resistant…

Once dismissed as 'junk DNA' that served no purpose, a family of 'jumping genes' found in tomatoes has the potential to accelerate crop breeding for traits such as improved drought resistance.

The origin of matter remains a complex and open question. A novel experimental approach could be exploited to better test the theories of physicists.

How people behave in one situation often tells us how they will act in others. A shy introvert in one place, for example, isn't likely to be the gregarious life of the party in another.

Valley fever is endemic to hot and dry regions like the southwestern United States and California's San Joaquin Valley, but a new study predicts climate change will cause the fungal infection's range to more than double in size this century, reaching…

A key question for climate scientists in recent years has been whether the Atlantic Ocean's main circulation system is slowing down, a development that could have dramatic consequences for Europe and other parts of the Atlantic rim. But a new study suggests…

Astronomers have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of existence, approaching the theoretical maximum mass possible for a…

The overall brightness of Tabby's Star has been gradually dimming for years. A new study suggests chunks of an exomoon's dusty outer layers of ice, gas and carbonaceous rock may be accumulating in a disk, blocking the star's light and making it appear to…

Researchers analyzed fish bones excavated from the Early Neolithic Jiahu site in Henan Province, China. By comparing the body-length distributions and species-composition ratios of the bones with findings from East Asian sites with present aquaculture, the…

Physicists have identified how to distinguish between true and 'fake' Majorana states in one of the most commonly used experimental setups, by means of supercurrent measurements. This theoretical study is a crucial step for advancing the field of topological…

Scientists describe a previously unknown disorder of the immune system: in a distinct subset of immune cells from patients with primary immunodeficiency, cellular respiration is significantly increased. This cellular metabolic overactivity leads to…

A restricted-sleep schedule built to resemble an American work week made study participants feel less full after a fatty meal and altered their lipid metabolism. One night of recovery sleep helped, but didn't completely erase the effects of sleep restriction.

Researchers published the first experiments to gauge whether biomimetic robotic fish can induce fear-related changes in mosquitofish, aiming to discover whether the highly invasive species might be controlled without toxicants or trapping methods harmful to…

In marriage, conflict is inevitable. Even the happiest couples argue. And research shows they tend to argue about the same topics as unhappy couples: children, money, in-laws, intimacy. So, what distinguishes happy couples? According to a new study, it is the…

By mimicking the outer coating of pearls (nacre, or as it's more commonly known, mother of pearl), researchers have created a lightweight plastic that is 14 times stronger and eight times lighter (less dense) than steel and ideal for absorbing the impact of…

Patients who attend 'Heart School', as almost every patient in Sweden is invited to do after a first heart attack, live longer than non-participating patients.

Researchers say they have evidence that hospital emergency departments (EDs) worldwide may be key strategic settings for curbing the spread of HIV infections in hard-to-reach populations if the EDs jump-start treatment and case management as well as diagnosis…
