The biology beneath the ice – Clark University News Hub

Posted: Published on March 2nd, 2017

Clark University doctoral candidate Melishia Santiago grew up with palm trees and warm weather near sunny Atlantic beaches in Florida and Puerto Rico before coming north to Massachusetts for college. Now, she spends her time thinking about ice, specifically how climate change impacts sea-ice extent in the western Arctic Ocean. The study area for Santiago's project is in the Bering, Chukchi and western Beaufort seas. The dark blue markings indicate the sampling stations for the NSF Arctic Observing Network Distributed Biological Observatory program. Santiago is researching the effects of sea-ice extent, or how much of a given space is considered ice covered, on the biology and biogeochemistry in the ocean water column in the Bering, Chukchi and western Beaufort seas of the Pacific Arctic Region along Alaskas coast. Shes looking at how a material called colored or chromophoric dissolved organic matter (CDOM) distribution is impacting sea-ice extent. In the Arctic Ocean, dissolved organic matter results from the decay of phytoplankton, or microscopic marine plants, by photosynthesis on ocean surface waters or when land-derived organic matter is transported by rivers to coastal areas. CDOM, the fraction of dissolved organic matter you can see in natural waters, absorbs light and affects heating … Continue reading →

The Biology of Morning Routines: Why Do We Have Them? – Huffington Post

Posted: Published on March 2nd, 2017

What are the most important parts of a morning routine? originally appeared on Quora - the place to gain and share knowledge, empowering people to learn from others and better understand the world. Answer by James Altucher, author, entrepreneur, podcaster, wall street investor, on Quora: They say, win the morning, win the day. I dont know what that means. Heres the only thing thats important in a morning routine: Brush your teeth. Brushing your teeth gets you moving, shakes your head a lot so you wake up, and gives you good breath. People hate to smell people with bad breath. And you cant miss with bad breath. Plus dental hygiene helps prevent strokes and heart disease because it prevents infections that can reach your brain or heart. And finally, you look better with better teeth. Its one of the few things I can control in my looks that only takes a few minutes a day. Did you know the leading cause of suicide in the 1800s was dental pain? Dental pain is the worst. If you don't do anything else in the morning, just do this. Heres what I do every morning, because I love doing this: First, be a … Continue reading →

How bioinformatics tools are bringing genetic analysis to the masses – Nature.com

Posted: Published on March 2nd, 2017

Illustration by the project twins For doctors trying to treat people who have symptoms that have no clear cause, gene-sequencing technologies might help in pointing them to a diagnosis. But the vast amount of data generated can make it hard to get to the answer quickly. Until a couple of years ago, doctors at US Naval Medical Research Unit-6 (NAMRU-6) in Lima had to send their sequence data to the United States for analysis, a process that could take weeks much too long to make pressing decisions about treatment. If all you could do was get the data that you then have to ship to the US, it's almost useless, says Mariana Leguia, who heads the centre's genomics and pathogen-discovery unit. But Leguia no longer has to wait for the analyses; she can get results in days or even hours and she can do them in her own lab. Her unit makes use of EDGE (Empowering the Development of Genomics Expertise), a bioinformatics tool that hides common microbial-genomics tasks, such as sequence assembly and species identification, behind a slick interface that allows users to generate polished analyses. We can have actionable information on site that allows us to make decisions … Continue reading →

Opinion: Set high expectations of women engineers and they’ll meet them – The Mercury News

Posted: Published on March 2nd, 2017

Almost every woman in engineering Ive talked to knows the pressure of having to prove herself. She knows what its like to be meticulously perfect in her calculations, and to accept that regardless of her intelligence, her work will be checked again by someone who doesnt trust her.She knows that at the end of the day, mistakes hold more weight than they should. I say almost every woman because I am one of the few that has rarely experienced this. Im lucky. Im an anomaly. Bioengineering at Santa Clara University has a relatively large percentage of female students, compared to the other engineering disciplines. Im not intimately familiar with gender tensions in the classroom because there arent any in the classes I take, and I rarely feel the need to prove that I am better than the men I work with. My mentors dont expect me to make mistakes, and are genuinely surprised when I do. Im not pressured to be perfect, but at the same time, the expectations for the work I do are just as high as anyone elses. The psychological effects of this are subtle, but theyve shaped how I perceive my own abilities, goals, and expectations. … Continue reading →

Decoding the Genome’s Cryptic Language – Bioscience Technology

Posted: Published on March 2nd, 2017

Bioengineers at the University of California San Diego have developed a new tool to identify interactions between RNA and DNA molecules. The tool, called MARGI (Mapping RNA Genome Interactions), is the first technology that's capable of providing a full account of all the RNA molecules that interact with a segment of DNA, as well as the locations of all these interactions -- in just a single experiment. RNA molecules can attach to particular DNA sequences to help control how much protein these particular genes produce within a given time, and within a given cell. And by knowing what genes produce these regulatory RNAs, researchers can start to identify new functions and instructions encoded in the genome. "Most of the human genome sequence is now known, but we still don't know what most of these sequences mean," said Sheng Zhong, bioengineering professor at the UC San Diego Jacobs School of Engineering and the study's lead author. "To better understand the functions of the genome, it would be useful to have the entire catalog of all the RNA molecules that interact with DNA, and what sequences they interact with. We've developed a tool that can give us that information." Zhong and his … Continue reading →

The anatomy of F1 drivers: from lightning reactions to superstrength necks – Telegraph.co.uk

Posted: Published on March 2nd, 2017

The neck In terms of extreme forces they endure, this season we anticipate a greater mechanical grip and faster cornering speeds so we would expect a possible increase in the lateral and longitudinal g-forces which will increase the load on the neck. The neck has to endure a 30-35% increase in load, so the equivalent of about an extra 30-40kg. Technogym is a partner of ours and they have provided a specific machine known as the F1 Training Machine which enables the drivers to sit in a very specific position and build the right strength. The steering wheel is plate-loaded so you can adjust the position and the load. The drivers can also wear a helmet with attachments of bungee cords which help provide some elastic resistance to simulate the loads they experience in the car. The drivers also need neuromuscular capabilities so their nervous system needs to be able to react quickly to stimulus on the track, whether that be a move by a fellow competitor, debris on the track, or information or instructions from the pit. They have to make quick decisions in seconds. Driving at such high speeds requires instant decision-making while controlling a million pound machine … Continue reading →

Relief From Itchy Eczema May Come In The Form Of A Shot : Shots … – NPR

Posted: Published on March 2nd, 2017

A new treatment may help reduce the itch of atopic dermatitis, which will reduce flare-ups. Meredith Rizzo/NPR hide caption A new treatment may help reduce the itch of atopic dermatitis, which will reduce flare-ups. People with moderate to severe eczema may benefit from new treatments that significantly reduce the intense itching that comes with the scaly skin disease. A study published Wednesday finds that the antibody nemolizumab, given as a monthly injection, not only reduces itching significantly but also clears up many of the patches of dry, inflamed skin that are part of the disease. It appears in the New England Journal of Medicine. "At 12 weeks there was very significant improvement," says dermatologist Jon Hanifin of the Oregon Health and Science University. "Not 100 percent, but patients were delighted not to have the itching that was keeping them up at night." The study was done in 216 patients with moderate-to-severe eczema to determine the best dose of nemolizumab. They were randomized to receive either a placebo or a low, moderate or high dose of the drug, injected once a month. Those who got the low dose reported a 44 percent reduction in itching, using a scale of 1 to … Continue reading →

Stress, low mood before pregnancy increases eczema risk in children: Study – Hindustan Times

Posted: Published on March 2nd, 2017

New UK research suggests that stress before conception can increase the risk of eczema in children. A first-of-its-kind study that links maternal stress before conception with the risk of atopic eczema in future children has been carried out by the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton in the UK. For the research, the study assessed the stress levels of women recruited to the Southampton Womens Survey before they were pregnant. Participants were asked to report how stressed they were in their daily lives with a sub-group also asked about their psychological wellbeing. Around 3,000 babies were born to women taking part in the survey, who were then assessed for eczema at the ages of six months and 12 months. The researchers say maternal stress can release certain hormones that can have an effect on the babys immune response. (Shutterstock) The results showed that more than one in six women reported that stress affected their health quite a lot or extremely before falling pregnant, with the analysis showing that the infants of these mothers had a 20% higher likelihood of developing atopic eczema at age 12 months when compared with the children of other participants. The results also … Continue reading →
