Many young children have unsupervised access to the internet and are using the internet to socialise with others.
What problems do children face when going online without parental supervision?
How can these problems be solved?

21st century is marked by the internet revolution and with coming of personal computers, kids often gravitate to them to play games, watch videos, interact socially and learn from educational websites. However, allowing your kids to access internet without any parental supervision opens them to potential risk.
One of the biggest problem facing children all across the world with unsupervised access is that they might share information with people they shouldn’t. The risk associated with sharing personal information includes revealing identifiable information that could provide criminals with the child’s location or children can share their parent’s financial information online, like the credit card number. To solve this problem, parents and teachers need to come together to aware children about the possible risks of sharing information and teach them the nitty gritty of online interaction.
Another issue is the exposure of the child to cyber bullying. Cyber bullying involves online harassment and it might occur in chat rooms, on social media websites and through email or text messages. With unsupervised access your child might either become the bully or the victim. This kind of bully is slowly gaining momentum and recent cases of suicides have left people shocked. The problem could be addressed by parents taking care of what the child is doing in internet. The communication between parents and the child must be friendly enough that the child can tell his/her parents of the issues she/he is facing.
To sum up, although it is clear that unsupervised access causes some major issues, it is undoubtedly possible to start to tackle these issues and use the internet in a more positive manner. Parents and teachers must take the lead in dealing with this problem, otherwise a whole lot of young lives will get disturbed.
More and more businesses as well as individuals are choosing to communicate either professionally or socially using technology rather than face to face interaction.
What are the advantages and disadvantages of using technology for communication?
Technology has brought about a considerable shift in the way communication between individuals and companies take place; a shift from the traditional face to face interaction towards online communication. However, the central question is whether the change is positive, or whether there are more drawbacks than advantages?
One of the major plus points of online interaction is there are less chances of fraud. No one can deny that they have said a particular thing as there is record of everything. For instance, if a company promises to offer its employee a bonus of 1000 and the information is sent via mail, the organisation cannot deny having send it. If it does, it has to prove that the mail was malicious.
Secondly, online interaction seems to fit in the busy world we live in. Most people don’t have time to travel, but they still can interact with people they want to in just a click. Even more, it bridges the gap between people living far away. Example- friends who don’t meet regularly can stay in touch using any of the social media sites.
On the other hand it can be very easy to get distracted if you are constantly chatting online. Like, in a recent survey it was found out that people who used social media tend to be lesser effective at work than those who avoided there use during work. Another major disadvantage of online interaction is the security issue. Since the entire communication is online, it is quite possible that someone might drop in the conversation and steal the important passwords or information.
To conclude, there are both positives and negatives to the use of technology for communication. In spite of the fact that it brings people together and eases communication, some people don’t find it reliable in case of secret information. Personally, I believe that although technology makes life easier one must not entirely depend on it for everything.

Now, researchers (A researcher is someone who conducts research, i.e., an organized and systematic investigation into something. Scientists are often described as researchers.)at Purdue University in Indiana have made two major improvements (the action of improving or being improved)to the approach, making it fast enough to be used in real-time and allowing imaging of not just transparent but also thicker, turbid living tissues. The results are published today (October 30) in Science Advances.
“This is a very innovative ( featuring new methods)approach,” said Wei Min of the department of chemistry at Columbia University in New York City who was not involved in the study. “And the instrumentation (measuring instruments regarded collectively)the authors built is quite impressive (evoking admiration through size, quality, or skill; grand, imposing, or awesome).”
“This is good progress toward making this technique (a way of carrying out a particular task, especially the execution or performance of an artistic work or a scientific procedure)more practical,” said bioengineering (the use of artificial tissues, organs, or organ components to replace damaged or absent body parts)professor Stephen Boppart, who develops novel imaging modalities (a particular mode in which something exists or is experienced or expressed)at the University of Illinois and was not involved in the work. “The authors have made the acquisition (the learning or developing of a skill, habit, or quality)faster, allowing image collection in vivo and in highly photon scattering (the process in which electromagnetic radiation or particles are deflected or diffused)tissues.”
While fluorescence microscopy requires labeling a cellular component with a fluorophore, the appeal of in vivo vibrational spectroscopic ( the study of the interaction between matter and electromagnetic radiation. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism)imaging is the ability to produce images that include most of the endogenous (having an internal cause or origin)molecules within tissues or cells without the need to label any cellular components. The original technique sends light through a sample, exciting the molecules in the sample to vibrate at distinct frequencies, which are then registered (enter or record on an official list or directory)as a spectrum or a pattern of peaks. For each pixel, a spectrum (a band of colours, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength)of frequencies (the rate at which something occurs over a particular period of time or in a given sample)is created and an image is compiled (produce (a list or book) by assembling information collected from other sources)by merging (combine or cause to combine to form a single entity)all of the spectra. A spectrometer (an apparatus used for recording and measuring spectra, especially as a method of analysis)collects the well-directed light that goes through the same, and separates it into its individual wavelengths (a person’s ideas and way of thinking, especially as it affects their ability to communicate with others)while excluding scattered photons—components of light—that decrease the resolution of the light’s spectrum. This method is limited to use for transparent (allowing light to pass through so that objects behind can be distinctly seen.)and single-cell layer biological samples because nontransparent (not able to be seen through; opaque)samples, such as live tissue, scatter too many photons, resulting in poor resolution (the quality of being determined or resolute).
Defying(to challenge the power of)predictions (foretell a future), President Recep Tayyip Erdogan’s Justice and Development Party, the A.K.P., won a conclusive (convincing)victory (asuccessortriumphoveranenemyinbattleorwar)in Sunday’s national elections in Turkey, freeing it from the need to form a coalition (acombinationoralliance,especiallyatemporaryonebetween persons,factions,states,etc.)to stay in power. Mr. Erdogan proclaimed (toannounceordeclareinanofficialorformalmanner)it a vote “in favor of stability,” and that is what it apparently (readily seen)was — though it was Mr. Erdogan who churned (tobechangingrapidlyorbeinaconfusedstate)up much of the turmoil (astateofgreatcommotion,confusion,ordisturbance;tumult;agitation)that frightened (afraid)voters back into his camp.

Though the A.K.P. won about half the vote, it did not gain enough seats in Parliament to enable Mr. Erdogan to change the Constitution to create the strong executive (pertainingtoorchargedwiththe execution oflawsandpoliciesorthe administrationofpublicaffairs)presidency he has sought since he assumed the office last year. But the A.K.P. majority will mean a continuation (extension or carrying to further point)of 12 years of one-party rule, and most probably a continuation of Mr. Erdogan’s increasingly authoritarian (oforrelatingtoagovernmentalorpoliticalsystem,principle,or practiceinwhichindividualfreedomisheldascompletelysubordinate tothepoweror authority ofthestate,centeredeitherinonepersonor asmallgroupthatisnotconstitutionallyaccountabletothepeople)domination (the act or instance of dominating)of the Turkish government.
Mr. Erdogan engineered (apersonwhooperatesorisinchargeofanengine)Sunday’s vote after the last elections, on June 7, not only failed to secure the seats he needed for his presidential scheme, but cost the A.K.P. its majority and allowed a pro-Kurdish coalition, the Peoples’ Democratic Party, to enter Parliament for the first time. Instead of helping to form a coalition government after that vote, Mr. Erdogan called for new elections.
In the intervening (tocomebetweendisputingpeople,groups,etc.)time Turkey resumed (totakeuporgoonwithagainafterinterruption) bombing attacks on Syrian Kurds and violence flared (tostartuporburstoutinsudden,fierceactivity,passion,etc.)in the country’s volatile southeast. Opposition politicians were assailed (toattackvigorouslyorviolently)and the government’s longstanding (existing or occurring for a long time) harassment (theactoraninstanceof harassing, ordisturbing,pestering,or troublingrepeatedly;persecution)of the news media reached new levels. On the eve of the election, the police raided (asuddenassaultorattack,asuponsomethingtobeseizedor suppressed)the last television channels critical of Mr. Erdogan, which had belonged to an Islamic movement that had gone from support of Mr. Erdogan to fierce opposition.
In the early years of A.K.P. rule, Mr. Erdogan had been hailed (tocheer,salute,orgreet)in Europe and the United States as the face of moderate Islam. Turkey’s economy (themanagementoftheresourcesofacommunity,country,etc.,especiallywithaviewtoitsproductivity)bloomed (to flourish or thrive), human rights improved as Turkey sought membership in the European Union and Mr. Erdogan achieved a cease-fire with Kurdish rebels (apersonwhorefusesallegianceto,resists,orrisesinarmsagainstthe governmentorrulerofhisorhercountry). But much of that has been undermined (toweakenorcausetocollapsebyremovingunderlyingsupport,asby diggingawayorerodingthefoundation), and Mr. Erdogan has come under increasing criticism (theactofpassingjudgmentastothemeritsofanything)in the West, as he has turned steadily toward authoritarian (favoringcompleteobedienceorsubjectionto authority asopposedto individualfreedom)rule, assisted by his ally (toassociateorconnectbysomemutualrelationship,asresemblance orfriendship)and prime minister, Ahmet Davutoglu.
