Waves move across the human brain to support memory

Jun 07 2018 - 00:06
Columbia Engineers have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The researchers also found that the traveling waves moved more reliably when subjects performed well while performing a working memory task, indicating traveling waves are important for memory and cognition: the waves play a significant role in supporting brain connectivity.

How to suck carbon dioxide from the sky for fuels and more

Jun 07 2018 - 00:06
Someday, the gasoline you buy might come from carbon dioxide pulled out of the sky rather than from oil pumped out of the ground. By removing emitted carbon dioxide from the atmosphere and turning it into fresh fuels, engineers at a Canadian firm have demonstrated a scalable and cost-effective way to make deep cuts in the carbon footprint of transportation with minimal disruption to existing vehicles. Their work appears June 7 in the journal Joule.

Study of sleeping fur seals provides insight into the function of REM sleep

Jun 07 2018 - 00:06
All land mammals and birds have two types of sleep: rapid eye movement (REM) and non-REM (also called slow-wave sleep). Earlier evidence had suggested that REM sleep is essential for physical and mental well-being and learning, but the underlying function of REM sleep has been a mystery. Now researchers reporting in Current Biology on June 7 have new insight into the function of REM sleep, based on studies of an unlikely animal: the fur seal.

In male dolphin alliances, 'everybody knows your name'

Jun 07 2018 - 00:06
It's not uncommon in dolphin society for males to form long-lasting alliances with other males, sometimes for decades. Now, after studying bottlenose dolphins in Shark Bay, Australia, for more than 30 years, researchers reporting in Current Biology on June 7 find that these males retain individual vocal labels rather than sharing a common call with their cooperative partners.

Physicists developed self-propelled droplets that can act as programmable micro-carriers

Jun 07 2018 - 00:06
In the life sciences, researchers are working to inject drugs or other molecules into a human body using tiny 'transport vehicles.' Researchers at the Saarland University and the University of Barcelona have shown in a model system that small emulsion droplets can be used as smart carriers. They have developed a method for producing self-propelled liquid droplets capable of providing spatially and temporally controlled delivery of a 'molecular load'. The study was published in 'Communications Physics'.

Who should be on the $10 and $20 bills? How race, gender, & politics shape public opinion

Jun 07 2018 - 00:06
Race, gender, political affiliation, and the prejudices and biases associated with them (racism, sexism, and political ideology) seem to be at the forefront of citizen's minds when it comes to preferences for US currency -- specifically, who should be on the $10 and $20 bills.

In a hole in a tunicate there lived a hobbit: New shrimp species named after Bilbo Baggins

Jun 07 2018 - 00:06
A new species of shrimp was named after Tolkien's Bilbo Baggins thanks to its small size and hairy feet. The new species, Odontonia bagginsi, was described, figured and named together with another new species: Odontonia plurellicola. Both shrimps live symbiotically inside tunicates collected around Ternate and Tidore, Indonesia. In the present study, published in the open access journal ZooKeys, anatomical and genetic characters were used to place the new species in the tree of life.

Immunoscore: A test to improve the care and treatment of colon cancer

Jun 07 2018 - 00:06
With Immunoscore, a test devised by a team of researchers from Inserm and Université Paris Descartes and doctors from the Paris AP-HP hospitals, disease progression in patients with colon cancer can now be defined more accurately. According to an international study conducted in more than 2,500 patients, Immunoscore has proved effective in predicting which patients are at high risk of tumor recurrence and, as such, would benefit from intensified treatment following surgery. These results have been published in The Lancet.

How solar prominences vibrate

Jun 07 2018 - 00:06
An international team led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) has cataloged around 200 oscillations of the solar prominences during the first half of 2014. Its development has been possible thanks to the GONG network of telescopes, of which one of them is located in the Teide Observatory.

Understanding how drug reduces confusion in older patients after surgery may lead to better care

Jun 07 2018 - 00:06
A drug that reduces delirium in postoperative patients may work by preventing the overactivity of certain receptors in brain cells, according to a new study published in the Online First edition of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA). The researchers say the findings could lead to more widespread use of the drug, dexmedetomidine, and speed the development of new treatments for postoperative delirium with fewer side effects.

Breaking through a tumor's defenses

Jun 07 2018 - 00:06
In research published today, Babraham Institute researchers have shown that some tumors use not one but two levels of protection against the immune system. Knocking out one level boosted the protective effects of the second and vice versa. The research demonstrates that a two-pronged approach targeting both cell types simultaneously may offer a promising route for the development of new cancer immunotherapies.

Researchers discover multiple alkali metals in unique exoplanet

Jun 07 2018 - 00:06
Scientists from the Instituto de Astrofísica de Canarias (IAC) and the University of Cambridge have observed with the Gran Telescopio Canarias (GTC) a rare gaseous planet, with partly clear skies, and strong signatures of alkali metals in its atmosphere.

Researchers from the UPC and the IAC discover one of the most massive neutron stars

Jun 07 2018 - 00:06
Using a pioneering method, researchers from the Astronomy and Astrophysics Group of the Universitat Politècnica de Catalunya (UPC) and the Instituto de Astrofísica de Canarias (IAC) have found a neutron star of about 2.3 Solar masses--one of the most massive ever detected. The study was published on the 23rd of May in The Astrophysical Journal and opens a new path of knowledge in many fields of Astrophysics and Nuclear Physics.
