Caribbean Sea acts like a whistle and can be 'heard' from space

A study of the Caribbean Sea by University of Liverpool ocean scientists has revealed that, in the midst of all the noise of the ocean, this region behaves like a whistle, which blows so loudly that it can be 'heard' from space in the form of oscillations of the Earth's gravity field.

The Caribbean Sea is a part of the Atlantic Ocean, southeast of the Gulf of Mexico. It is a bounded by South America, Central America and the Caribbean islands, and covers an area of approximately 2,754,000 km2 (1,063,000 square miles).

New CAR T cell therapy using double target aimed at solid tumors

PHILADELPHIA - Chimeric antigen receptors (CARs), engineered from a patient's own immune cells, have been successful for treating blood cancers, but using CARs for solid tumors has been limited by side effects to normal tissues containing the protein targeted by the engineered cells.

Pollen allergies have increased among Swedish adults

The prevalence of pollen allergies among adults in Sweden has increased. However, the prevalence of allergies to furred animals, mites or mold has not. These were the results of a new study at Sahlgrenska Academy.

The prevalence of allergic diseases has increased since the mid-1900s, and today, approximately one fourth of Swedish adults has hayfever, while 10 percent suffer from asthma.

Asthma and hayfever are strongly linked to allergic sensitization, that is the prevalence of antibodies against allergens, for example, from pollen or furred animals.

Fighting experience makes beetles better mothers, study shows

Female beetles that are seasoned fighters put more effort into raising their offspring than mothers with no conflict experience, a study suggests.

Beetles that are used to conflict spend twice as much time providing food for their offspring as those that have never fought, helping more of their young to survive, researchers say.

Female burying beetles - which belong to the species Nicrophorus vespilloides - routinely fight over the carcasses of small birds and rodents, which they use to provide their young with food.

New study finds link between omega-3 supplementation and reduced hospital stays

A new meta-analysis published in Clinical Nutrition found that cardiac surgery patients who received omega-3 polyunsaturated fatty acids (compared to placebo) in advance of surgery experienced reduced postoperative cardiac arrhythmias and significantly reduced the length of hospital stay by up to 2.4 days. The results are based on 11 RCT's with 1038 patients.

Drones could be cheaper alternative to delivering vaccines in developing world

Using unmanned drones to deliver vaccines in low- and middle-income countries may save money and improve vaccination rates, new research led by the Johns Hopkins Bloomberg School of Public Health and the Pittsburgh Supercomputing Center suggests.

The cost savings would come from drones being able to deliver vaccines more quickly and cheaply than land-based methods limited by road conditions and the need for costly fuel and maintenance, the researchers note in their study, published June 20 in the journal Vaccine.

Experts take strong stance on testosterone deficiency and treatment

BOSTON - In an effort to address widespread concerns related to testosterone deficiency (TD) and its treatment with testosterone therapy, a group of international experts has developed a set of resolutions and conclusions to provide clarity for physicians and patients. At a consensus conference held in Prague, Czech Republic last fall, the experts debated nine resolutions, with unanimous approval. The details of the conference were published today in a Mayo Clinic Proceedings report.

Versatile method yields synthetic biology building blocks

Synthetic biology involves creating artificial replica that mimic the building blocks of living systems. It aims at recreating biological phenomena in the laboratory following a bottom-up approach. Today scientists routinely create micro-compartments, so called vesicles, such as liposomes and polymersomes. Their membranes can host biochemical processes and are made of self-assembled lipids or a particular type of polymers, called block copolymers, respectively.

Measuring Planck's constant, NIST's watt balance brings world closer to new kilogram

A high-tech version of an old-fashioned balance scale at the National Institute of Standards and Technology (NIST) has just brought scientists a critical step closer toward a new and improved definition of the kilogram. The scale, called the NIST-4 watt balance, has conducted its first measurement of a fundamental physical quantity calledPlanck's constant to within 34 parts per billion - demonstrating the scale is accurate enough to assist the international community with the redefinition of the kilogram, an event slated for 2018.

Pilot study successfully uses DNA sequencing to diagnose brain infections

In a proof-of-principle study, a team of physicians and bioinformatics experts at Johns Hopkins reports they were able to diagnose or rule out suspected brain infections using so called next-generation genetic sequencing of brain tissue samples.

Overweight and obese type 2 patients show improvements with structured nutrition therapy

Boston (June 20, 2016) - Researchers at Joslin Diabetes Center have announced the results of a study that may change how nutrition therapy is delivered to overweight and obese patients with type 2 diabetes. The "Nutrition Pathway Study" compared three models of nutrition therapy and found that a highly structured nutrition plan provides the most significant impact on A1C, body weight and lipid profiles. The study results were presented at the American Diabetes Association's 76th Scientific Sessions in New Orleans, Louisiana.

UMMS scientists use CRISPR to discover Zika and dengue weaknesses

WORCESTER, MA - Scientists at the University of Massachusetts Medical School (UMMS) have performed the first CRISPR/Cas9 screen to discover human proteins that Zika virus needs for replication. This work, led by Abraham Brass, MD, PhD, assistant professor in microbiology & physiological systems, reveals new leads that may be useful for halting Zika, dengue and other emerging viral infections. The study appears online in the journal Cell Reports.

Strong global economic engagement is essential for US prosperity, RAND study says

The United States stands to gain more from both strengthening global institutions and rules, such as those governing trade, direct investment, and development assistance as well as engaging with the world's rising powers than from pulling back, a new RAND Corporation study argues.

The country is likely to remain the world's largest economy for many years, and can benefit from strengthening its leadership role in the international economic structures that it helped create, according to researchers.

Sierra Nevada snowpack not likely to recover from drought until 2019

Even with this winter's strong El Niño, the Sierra Nevada snowpack will likely take until 2019 to return to pre-drought levels, according to a new analysis led by UCLA hydrology researchers.

Additionally, they suggest their new method, which provided unprecedented detail and precision, could be useful in characterizing water in the snowpack in other mountains, including ranges in western North America, the Andes or the Himalayas. These areas currently have much less on-site monitoring than in the Sierra Nevada.
