Graphene oxide is being looked upon as a possible non-toxic and a very durable option for dental fillings that will not easily corrode, researchers say. Presently, filings used are made of metals like mercury, copper, silver and tin, or composites of ceramic and powdered glass. Both these fillings re prone to corroding and aren’t very strong. On the other hand, graphene is 200 times stronger compared to steel and does not corrode – the reason why researchers are now considering it as a likely option for dental fillings. The  recent  researches  throwing  new  light   on  the  cytotoxic  properties  of   graphene  based   materials   and  the potential     of  being   used  as  dental  fillings;Said  Andriana   philip, associate  professor   at  Iulio   Hatieganu   University   of  medicine  and Pharmacy   in Romania.   The next step for this research is for the team to make dental materials with graphene oxide and test how compatible they are with teeth, and how toxic the

Scientists   in  Finland    have  developed   a  new  technology  for  smart  clothing  that  automatically  adjusts  its  temperature  depending  on  the  wearer's  need. The  technology   can  be  utilized  in  smart  fabrics   and  clothing  that  are  able  to   calculate  whether   the  wearer need   to  be  cooled  or  warmed  based  on  initial  data  measured  from   the  person  and  the  environment . Further more  this  technology is  able  to  determine  the  needed   warming  or cooling  power  so  that  the  thermal  sensation  of  the  person  wearing  the  cloth   remains  optional in  varying  condition,  according  to   researchers  of  at  VTT  Technical   Research  Center The   technology  is  based   on  the  Human  Thermal  Model   calculation  tool,  which  measures a  person's   individual    thermal   sensation  from  the  prevailing   conditions. There  are  also   significant    differences  between  men  and  women, due  to  the  fact  that  men

Lemon juice is vital for many of its uses at home, plus it has real healing power. After use of the fruit or the juice, keep the peels, as they have some uses. (Freezing them is a great option!) Lemons provide a natural remedy to some ailments and they are also helpful for in cleaning, beauty care, and cooking — plus they smell great. The juice left in the rind of the fruit can be helpful in lightening age spots and for cooking in the kitchen. Lemons have antibacterial properties that make it very useful for clean cutting boards and other surfaces. Some  other  uses  of  lemon  peels  are  - Reduces Cholesterol in the Body Lemon peels are also effective at reducing the cholesterol levels in the body, ensuring that the heart has a better chance of maintaining a healthy state. This is also due to the high levels of flavonoids present in the peels. Less cholesterol in the body means better well being. Remove Odors From Hands If you've ever

Scientists   have  claimed   that  within  five  years  the extinct  woolly  mammoth  could  be  brought    back  to  life    from  the  bone  marrow of  the  species.A  team  from Russia's    Sakha's  Republic 's mammoth  museum   and Kinky  University  in Japan  says   that the  recent discovery  well  preserved   marrow  inside  the  thigh   bone  of   a woolly  mammoth  in Siberia    has  raised the  hope  that  the species  could   be cloned .By  replacing  the nuclei  of  egg   cells from  an  elephant  with  those   taken   from  the  mammoth's  marrow cells  , embryos  with  mammoth  DNA.can  be  produced. This   embryo  then  be  plant  into  elephant    wombs   for   delivery  as  the  two  species are  close  relatives.Securing  nuclei   with  an undamaged  gene  is essential  for   the  nucleus   transplantation  technique. Mammoth  became  extinct about  10,000  years  ago.

' LAUGHTER  IS  THE  SHORTEST   DISTANCE  BETWEEN  TWO PEOPLE"  Says   Victor  Borge.It   strengthen   relationships  by  triggering   positive  feeling  and  fostering  emotional   connection. Laughter   begins  with  birth .It  is   innate  and  inborn.Infants   begin  smiling  during  the   first  weeks  of  life  and   and  laugh  out  loud   within  months   of  being   born. Laughter  and  humor ,play,  having  fun  with others   not  only   make  life  more  enjoyable ,  it  helps   you  solve  problems,connect  with  others  and  be   more  creative .Then  ,  it   triggers   healthy  physical  changes      in  the  body   strengthening    the  immune  system ,  boosting  your   energy , diminishing  pain,lightens   your  burdens   and  brings   in  new  hope  and  positivity.  A   good  hearty   laugh   relieves    physical    tension     and  stress,    leaving  your   muscles  relaxed   for   upto   45    minutes  after.  it decreases   stress    har

WALKING     IS  THE    MOST   SIMPLE    BUT    MOST  USEFUL    EXERCISE.It     has     many    advantages  and   is  very   simple  .Our    ancestors    were  aware    of  its    advantages   but   they   did  not      know      the    precise    physical     effects     of  walking .Modern     medicine   and  doctors    today       make      assertions   about  the    benefits  of  brisk  walking   that  have  a  sound     basis    in   medical    fact. Noted     heart     specialist   Dr.  Paul   Dudley   White     said  ;" it    is the  easiest     exercise   for   most  individuals   ,one that  can  be  done   without  equipment   except   good  shoes in  most  terrain    and  weather     and  into  very    old  age."He     further   says   " A    vigorous     five -     mile     walk    will      do    more  good    for   an   unhappy ,  but  otherwise   healthy   adult   than  all    the   medicine   and    psychology        in  the  world."

Lightning strikes   can also be deadly. With a power of 300 kilo volts, lightning can heat the air up to 50,000 degrees Fahrenheit. This combination of power and heat can cause serious damage to the human body. Being struck by lightning may lead to burns, rupturing of the eardrum, eye damage, cardiac arrest, and respiratory arrest. While about 10 percent of lighting strike victims are killed, many of the 90 percent that survives are left with lasting complications. Lightning is a result of the build-up of electrostatic charge in clouds. The top of the cloud typically becomes positively charged and the bottom of the cloud becomes negatively charged. As the separation of charges increases, the negative charges may jump toward the positive charges in the cloud or toward positive ions in the ground. When this happens, a lightning strike occurs. There are typically five ways in which li

A   NEW  study  has  revealed   that    working  for  more than   40  hours  a  week   may  increase    one's  risk   of  developing  coronary  heart  disease ,or  narrowing   of   the  blood  vessels  that  supplies  blood  and oxygen  to  the  heart. According  to  Dr  Yul Chul  Hong,  Senior  author  of   the  study , from  the  Department   of  preventive  Medicine , Seoul  National  University, the   longer hours    employees  worked  , the  higher  their  chances   of  developing  coronary  heart  disease  within  ten  years, with  those  working  61   to  70  hours  having  a   42%   increased  likelihood   of  developing   the  disease ,  those  working  71  to  80  hours  having  a   63%  increased  likelihood   and  those  working   more  than   80  hours  having  a  94%   increased   likelihood.

A hormone is a specific molecule that acts as a chemical messenger in the endocrine system. Hormones are produced by specific organs and glands and are secreted into the blood or other body fluids. Most hormones are carried by the circulatory system to different areas of the body, where they influence specific cells and organs. Hormones regulate various biological activities including growth; development; reproduction; energy use and storage; and water and electrolyte balance. Hormone Signaling Hormones that are circulated in the blood come in contact with a number of cells. However, they only influence certain target cells. Target cells have specific receptors for a specific hormone. Target cell receptors can be located on the surface of the cell membrane or inside of the cell. When a hormone binds to a receptor, it causes changes within the cell that influence cellular function. This type of hormone signaling is described as  endocrine signaling because the hor

Life in zero gravity is much different than life on Earth.  We   get to enjoy both the taste and the smell of drinking hot coffee from a mug. Astronauts on the International Space Station don’t have this luxury and must drink their coffee using a straw that draws the liquid out of a closed container. This diminished coffee experience may change for the astronauts thanks to a new 3D-printedcup designed to help NASA study the behavior of fluids in micro-gravity. The idea for studying coffee and other liquids consumed in space surfaced after Italian European Space Agency astronaut Samantha Cristoforetti received an espresso machine. The opportunity to study capillary flow, liquid containment, and low-gravity fluid dynamics was too great to pass up. A team of researchers was assembled by NASA, and they went to work designing six different transparent polymer cups for use on the space station.  Five of the cups hold 150ml, while the sixth, a smaller 60ml vessel, was

Most college students don’t put self-care at the top of their to do lists.  It’s easy to ignore a task that doesn’t come with a deadline and  that task is simply “taking care of yourself”. Embrace the excitement and intensity of college life, but remember that maintaining your physical, mental, and emotional health is essential to your success and well-being. If you’re feeling stressed or overwhelmed, don’t punish yourself by pushing your mind and body to their limits. Instead, take time out to take care of yourself with some of these self-care strategies.   Get Away for Some Alone Time  If you live with roommates, privacy can be hard to come by, so  try   to find a peaceful place on campus to call your own. A  corner in the library, a shady spot in the quad, and even an empty classroom are all perfect places to retreat and recharge.     Take a Mindful Walk Around Campus When you’re going  to class, try this mindfulness exercise to
