Large Meta-Study Concludes Multivitamins Don't Improve Cardiovascular Health

Image
A new study has confirmed previous research, finding no evidence multivitamins are of any use in preventing heart attack or stroke or improving cardiovascular health.

A new meta-study, gathering data from over two million participants, has concluded that multivitamins and mineral supplements do not improve cardiovascular health or protect against heart attack and stroke. The systematic review suggests if a person is generally healthy then multivitamin/mineral dietary supplements confer no cardiovascular benefits.

Back in May a massive meta-analysis comprising 179 different clinical trials concluded that most common vitamin supplements provided no health benefits. Whereas that study broadly evaluated data across all causes of mortality, this new meta-study homed in on specific issues related to cardiovascular health.

After a broad literature search, the researchers targeted 18 specific studies to include in the meta-analysis. Over two million subjects were evaluated, with an average fo…

Seawater-Powered Generator

A new method of drawing direct electrochemical energy from seawater means submersible robots, vehicles and detectors could go deeper and longer into the unknown.
The test-system – which the team states is corrosive-resistant and able to tolerate numerous mode-switches – successfully ran continuously in high-energy (i.e. low power) mode for four days straight with no apparent power-loss.

Deniz suyundan doğrudan elektrokimyasal enerji çekmenin yeni bir yöntemi, suya batırılabilir robotların, araçların ve dedektörlerin bilinmeyene daha derin ve daha uzağa gidebileceği anlamına gelir.

Takımın korozyona dayanıklı olduğunu ve çok sayıda mod anahtarını tolere edebildiğini belirttiği test sistemi - açıkça kesin bir güç kaybı olmadan dört gün boyunca yüksek enerjili (yani düşük güç) modunda başarıyla çalıştı.

Sunscreen Chemicals Enter Bloodstream But Health Risks Unclear

Image
Four chemicals in sunscreen were found to leech into people's bloodstreams at levels high enough to warrant further safety testing.
A new study has found that four active ingredients in sunscreen can leech into a person's bloodstream at levels high enough to warrant further toxicology testing. Cancer experts say while these results do demand more clinical research, it's unclear whether these chemical concentrations are dangerous to humans and at this stage no one should discontinue their use of sunscreen.
The study involved four groups, with each group testing one of four different commercially available sunscreen formations: one lotion, one cream, and two different sprays. Each group applied the sunscreen formulation to 75 percent of the body, four times per day, for four days.
Regular blood tests closely examined the participants for plasma concentrations of four key sunscreen chemicals: avobenzone, oxybenzone, octocrylene, and ecamsule. After just one day of administra…

Hammock Lets You Kick Back Just About Anywhere

Image
When you picture a hammock you probably imagine a stretch of fabric strung up between two trees, but lately we're seeing some imaginative ways to let them stand on their own. The aptly named Hang Solo is the latest of these to cross our desk, and uses a lightweight frame to suspend one's existing hammock in just about any location.
When you picture a hammock you probably imagine a stretch of fabric strung up between two trees, but lately we're seeing some imaginative ways to let them stand on their own. The aptly named Hang Solo is the latest of these to cross our desk, and uses a lightweight frame to suspend one's existing hammock in just about any location.
This time around it has fine tuned its approach to produce a smaller version for single-person hammocks and turned to crowdfunding, with environments like music festivals, the beach, balconies and sporting events in mind.
To that end, the Hang Solo is relatively light at 12 lb (5.4 kg), thanks largely due to the …

New Device Can Detect Fluoride Contamination In Water

Image
SION-105 is a device which can be used on-site by anyone. In addition, it is luminescent by default, but darkens when it encounters fluoride ions.
Concentration of fluoride over 2ppm can cause serious health issues.
Researchers have built a new device to accurately measure fluoride concentrations using only a few drops of water with even low contamination, finds a new study.
The device SION-105. It’s portable, considerably cheaper than ones in use now, and can be used on-site by anyone. In addition, it is luminescent by default, but darkens when it encounters fluoride ions.
Measuring fluoride at low concentrations with sufficient accuracy is expensive and requires a well-equipped chemical lab.
Kyriakos Stylianou at EPFL Valais Wallis in Switzerland said SION-105 detects fluorides by adding only a few droplets of water and by monitoring the colour change of the metal-organic frameworks (MOFs).

Hearing Difficulty Might Keep Older Patients Away From Health Care Routine

Image
A new research has revealed that hearing difficulty in old age is linked to lower involvement in health care routine.
Patients who are 65 years and above in age, with hearing difficulties, have lower involvement in their health care routine, according to a study. Poor hearing puts patients at risk for poor outcomes. For example, people with hearing loss may be unable to understand their doctor when she explains medication changes.
The study done on 13,490 adults of 65 years and above in age analysed `patient activation`, or the knowledge, skills and the confidence that enables them to actively follow their health care routine. The results of `no trouble` hearing were compared with those reporting `some trouble` hearing. The latter had 42 per cent higher risk of low `patient activation`.While some people who complained of a `lot of trouble` hearing, had a 70 per cent higher risk.
The authors of the study noted that if clinicians stay aware of the hearing troubles, their use of simple …
