Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job — to fertilize eggs? Researchers now show that animal sperm evolution become supercharged only when sperm swim inside females.

Engineers developed inexpensive methods to make ‘impossible materials’ that interact in unusual ways with microwave energy. Thin film polymers inkjet printed with tiny component patterns collect or transmit energy with much greater selectivity, sensiti…

A team analyzed how the surface topography on silicone breast implants influences health complications such as scarring, inflammation, and a rare type of lymphoma.

A recent study found that the risk of SARS-CoV-2 infection increased 30 percent for households with a recent birthday in counties with high rates of COVID-19, but no such jumps were seen in areas with low rates of infection. The findings suggest inform…

Researchers have discovered a method which will allow for faster communication systems and better energy saving electronics.

In the mid-2030s, multiple United States coastal regions may see rapid increases in the number of high-tide flooding (HTF) days, according to a new study. The combined effects of sea-level rise and natural fluctuations in tidal range are anticipated to…

Research has found that training stroke survivors to walk at a faster speed during recovery can help improve the brain function that enables people to walk and perform another task simultaneously, known as dual-task walking.

A child’s enjoyment of school at six years old is linked to their General Certificate of Secondary Education (GCSE) results aged 16, according to new research.

Scientists studying a common childhood cancer have made a major breakthrough which could lead to a cure for some youngsters who would not have survived the condition.

Researchers develop a new avian influenza vaccine using plant-based recombinant protein.

Researchers have examined the way in which SARS-CoV-2 reprograms the metabolism of the host cell in order to gain an overall advantage. In their study, the researchers were able to identify four substances which inhibit SARS-CoV-2 replication in the ho…

When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluorescence images from live cells, researchers have trained an artificial neural network to reliably recognize cells that a…

Summer holiday school catch-up programs to address gaps in knowledge after school closures need to support children who are still struggling due to social isolation.

A study using genetically modified mice shows that a protein called Nrf2 increases the expression of protective genes in the acrylamide-induced toxic response.

A research group used live tissue imaging for the first time to visualize the emergence of the mammary gland.

Depression in youth, between the ages of 10 and 24 years, is both a leading cause of stress and a possible risk factor for future diseases and impairment. Now, a study confirms that depression in childhood or adolescence is associated with higher level…

This model addresses the fact that most traditional climate models effectively ignore cities entirely, causing them to underestimate the frequency and severity of urban heat waves. Urban areas make up only 2-3% of the earth’s land, so their effect on g…

A study of ancient bones on South Australia’s Kangaroo Island has provided new information about the Island’s past fauna and an insight into how species may live there in the future.

A research team discovers that silver (Ag)-based antimicrobials can effectively combat antibiotic resistant Staphylococcus aureus by targeting multiple biological pathways via functional disruption of key proteins and can be further exploited to enhanc…

To tackle the challenge of global warming, scientists have been looking into green and sustainable methods of breaking down carbon dioxide in emissions and in the atmosphere. Now, a group of researchers have developed a novel, easy to synthesize compos…
