Nanoparticles target anti-inflammatory drugs where needed
Researchers at the University of Illinois at Chicago have developed a system for precisely delivering anti-inflammatory drugs to immune cells gone out of control, while sparing their well-behaved counterparts.

Oldest bit of crust firms up idea of a cool early Earth
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.

Stream of stars in Andromeda satellite galaxy shows cosmic collision
The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies.

Detailed measurements in living cells challenges classic model for gene regulation
In all living organisms, genes are regulated by proteins called transcription factors.

New insights into the origin of birds
The key characteristics of birds which allow them to fly -- their wings and their small size -- arose much earlier than previously thought, according to new research from the Universities of Bristol and Sheffield into the Paraves, the first birds and their closest dinosaurian relatives which lived 160 to 120 million years ago.

Researchers make the invisible visible
As the first in the world, researchers from Aarhus have shown that a new scanning technique can see changes in metabolism that have until now remained invisible, while they are taking place.

Researchers create synthetic version of heparin for use in kidney patients
Researchers at Rensselaer Polytechnic Institute and the University of North Carolina at Chapel Hill have created a synthetic form of low-molecular-weight heparin that can be reversed in cases of overdose and would be safer for patients with poor kidney function.

Scientists transform skin cells into functioning liver cells
Scientists at the Gladstone Institutes and the University of California, San Francisco, have made an important breakthrough: they have discovered a way to transform skin cells into mature, fully functioning liver cells that flourish on their own, even after being transplanted into laboratory animals modified to mimic liver failure.

Climate change won't reduce deaths in winter
New research published Sunday, Feb. 23, has found that climate change is unlikely to reduce the United Kingdom's excess winter death rate as previously thought.

Team converts sugarcane to a cold-tolerant, oil-producing crop
A multi-institutional team reports that it can increase sugarcane's geographic range, boost its photosynthetic rate by 30 percent and turn it into an oil-producing crop for biodiesel production.

Researchers pinpoint brain region essential for social memory
Researchers have determined that a small region of the hippocampus known as CA2 is essential for social memory, the ability of an animal to recognize another of the same species.

A key protein is discovered as essential for malaria parasite transmission to mosquitos
Scientists studying the sexual transformation of the malaria parasite have solved a long-standing mystery in parasite biology.

Mysterious polio-like illness found in 5 California children
Researchers have identified a polio-like syndrome in a cluster of children from California over a one-year period, according to a case report released today that will be presented at the American Academy of Neurology's 66th Annual Meeting in Philadelphia, April 26-May 3, 2014.

Researchers have identified a novel immunological mechanism of great importance for vaccine developm
Researchers have discovered the presence of a novel subtype of innate lymphoid cells in human spleen essential for the production of antibodies.

Scientists unlock a 'microbial Pompeii'
An international team of researchers have discovered a 'microbial Pompeii' preserved on the teeth of skeletons around 1,000 years old.

Policies to green the economy must underpin UK recovery: New report
The United Kingdom urgently needs a green economic strategy to move towards low-carbon prosperity, resource security and environmental quality, says a new report published today by University College London's Green Economy Policy Commission.

New technology detect cellular memory
In 2009, two women at BRIC, the University of Copenhagen joined forces to develop a new technology that could elucidate the mystery behind cellular memory.
