Probing the complex nature of concussion

Probing the complex nature of concussion
Concussion is a major public health problem, but not much is known about the impacts that cause concussion or how to prevent them. A new study suggests that the problem is more complicated than previously thought.

To prevent collapse of tropical forests, protect their shape

To prevent collapse of tropical forests, protect their shape
Scientists have made a fundamental discovery about how fires on the edges of tropical forests control their shape and stability. The study implies that when patches of tropical forest lose their natural shape it could contribute to the catastrophic transformation of that land from trees to grass.

Is there life adrift in the clouds of Venus?

Is there life adrift in the clouds of Venus?
In the search for extraterrestrial life, scientists have turned over all sorts of rocks. Mars, for example, has geological features that suggest it once had -- and still has -- subsurface liquid water. Scientists have also eyed Saturn's moons as well as Jupiter's as possible havens for life in the oceans under their icy crusts. Now, however, scientists are dusting off an old idea that promises a new vista in the hunt for life beyond Earth: the clouds of Venus.

Cat-like 'hearing' with device tens of trillions times smaller than human eardrum

Cat-like 'hearing' with device tens of trillions times smaller than human eardrum
Researchers are developing atomically thin 'drumheads'-- tens of trillions of times thinner than the human eardrum -- able to receive and transmit signals across a radio frequency range far greater than what we can hear with the human ear. Their work will likely contribute to making the next generation of ultralow-power communications and sensory devices smaller and with greater detection and tuning ranges.

Uncovering clue to disarm gonorrhea superbug

Uncovering clue to disarm gonorrhea superbug
Researchers have discovered a way the gonorrhea bacteria cleverly evade the immune system -- opening up the way for therapies that prevent this process, allowing the body's natural defenses to kill the bug.

Can a Mediterranean diet pattern slow aging?

Can a Mediterranean diet pattern slow aging?
A series of six articles finds new correlations between a Mediterranean diet and healthy aging outcomes -- while also underscoring the need for careful approaches to the use of data in order to measure the diet's potential benefits.

Is your Easter egg bad for the environment?

Is your Easter egg bad for the environment?
A recent study has looked at the carbon footprint of chocolate and its other environmental impacts. It has done this by assessing the impacts of ingredients, manufacturing processes, packaging and waste.

A novel test bed for non-equilibrium many-body physics

A novel test bed for non-equilibrium many-body physics
The behavior of electrons in a material is typically difficult to predict. Novel insight comes now from experiments and simulations performed by physicists who have studied electronic transport properties in a one-dimensional quantum wire containing a mesoscopic lattice.

Computer searches telescope data for evidence of distant planets

Computer searches telescope data for evidence of distant planets
MIT researchers have used physics principles to improve the performance of a machine-learning system, trained on data from a NASA crowdsourcing project, that searches astronomical data for evidence of debris disks around stars, which can indicate the presence of an exoplanet.

Basking sharks gather in large groups off northeast US coast

Basking sharks gather in large groups off northeast US coast
Groups of basking sharks ranging from as few as 30 to nearly 1,400 individual animals have been observed aggregating in waters from Nova Scotia to Long Island. While individual sightings are fairly common, seeing large groups is not. The reason why the animals congregate has not been clearly determined, and observations of these aggregation events are relatively rare.

Stroke affects more than just the physical

Stroke affects more than just the physical
A new study looks at what problems affect people most after a stroke and it provides a broader picture than what some may usually expect to see. Stroke affects more than just physical functioning.
