Researchers at the Australian National University have found a way to make microscope probes 20 times more sensitive and able to identify forces as tiny as the weight of a virus. The technique requires laser beams to cool a nanowire probe ti minus 265 degrees Celsius. According to Ben Buchler from the ANU Research School of Physics and Engineering, the level sensitivity is accurate enough to detect the weight of a virus that is 100 billion times lighter than a mosquito.

 

The research has obvious medical and practical implications, as it can enhance the resolution of atomic-force microscopes. Atomic-force microscopes obtain a very precise measurement of the microscoping characteristic of a specimen by scanning a wire probe over the surface. The probes are, however, susceptible to vibration. With this new technique the vibrations can be stopped through cooling. Ping Koy Lam, a professor with ANU explains that at room temperature the probe vibrates interfering with the accuracy of the measurement. The lasers can stop the vibration. The lasers make the probe warp and move due to the heat but the movement can be controlled and the scientists were able to manipulate the warping to counter the thermal vibration of the probe.

The probe, however, can not be operated while the laser is on, it has to be switched off first and measurement needs to be taken before the probe warms up again.

Arapaima fish which measures 10 feet (3 meters) long and weighing about 400 pound (180 kgs) is considered the largest fish on the Amazon basin are depleting gradually. It’s surprising how a massive fish goes on missing.

A recent article based on the study of fishing communities in Amazon Brazil, states that this large fish is non-existent in few parts of the Amazon Basin. And remaining parts reports a major fall off of these fishes.

Scientifically named Arapaima gigas, pertains the characteristic of breathing in air. A major reason contributing to this feature is that it dwells in oxygen- poor waterways according to Tennessee Aquarium.

“Arapaima breeds on the extremity of floodplain forests and appears on the surface to breathe periodically every 5 to 15 minutes and this is the time when they are targeted easily and hunted by fishers with their own home made canoes,” stated by Caroline Arantes, a doctoral student in wildlife and fisheries science at Texas A&M University in College Station, who helped in this research conduct.

 

Among five species known of Arapaima, three are already lost or unnoticed for a decade and a century ago all of the five species were dwelling here.

“Saddest part of all is, that in spite of the extinction of these, fishers are continuously harvesting these fishes,” said study leader Leandro Castello, an assistant professor of fisheries at Virginia’s Tech College of Natural Resources and Environment, in Blacksburg.

Interestingly Arapaima are not killed in the usual way as the other fishes are harvested instead of that fishers are formulating their own way of preying them using gill nets for the smaller one. Local fishers are not intended to kill the smaller fishes but still while harvesting them, end up killing whatever comes in their way and hence there is large scale depletion.

There is good news along with it, few communities have framed rules such as banning on use of gill nets and restricting minimum capture size for arapaima, is seen to have 100 times more density of these fishes than others, were there are no restrictions for fishing.

Samsung intends to launch two new smart phones with a gap of a few months. The company launched Galaxy Note 4 today in Berlin whereas Galaxy S6 will come a bit later. Samsung’s entire focus was on the launch of the Samsung Galaxy Note 4. Therefore, there are only a few rumors related to the next  flagship phone from the galaxy line.

The recent launch of Galaxy Note 4 provides an insight about the Galaxy S6. Although it is not yet released, but still people have started to a compare the two phones. Earlier, Galaxy Note 3 was considered as the company’s flagship, but now the Galaxy Note 4 swapped it.

Samsung has fulfilled all the expectations of customers associated with the Galaxy Note 4. It came with a 5.7 inch Quad HD display, speedy processor, new 16 MP camera with the option of image stabilization and much more. On the whole, it is reasonable package which is expected to generate a great revenue for the company.

 

Although Samsung planned to unveil various products, but the most prominent are the Galaxy Note 4 and the Galaxy S5. The company sets out Galaxy S in April and up till now it is considered as the best option for all the Samsung lovers. Nevertheless, the anticipation of people is increasing for Samsung Galaxy S6. The features of Galaxy Note 4 which sheds some light on the future product of Samsung are as follows.

Display:

The Samsung Galaxy Not 4 has a Quad HD display that presents a sharper imagery and text. Quantum display is generally common for the smart phones which came in 2014. However, it is definitely a way better than the Full HD display.

Since the company has altered its display to Quad HD then there is no doubt that people can expect it in Galaxy S6 as well. The Galaxy Note 4 has established a standard, therefore it is certain that Galaxy S6 will maintain latest technology.

 

Design:

Samsung has always placed its line of Galaxy on the upside of all the other products. The company has  attached its product to the plastic design for several years and faced thousands of criticism since at that time the rivals started to offer metal designs. Eventually the company ended its own tradition and begin to manufacture plastic designs with metal border. The new Galaxy Note 4 has a plastic back along with a metal band which is present at the side of the device.  Therefore, it is predicted that Samsung S6 will come with a design similar to Galaxy Note 4. It demonstrates that the company has started listening to its customers.

Although, the sources are unable to obtain a single leaked picture of the future product. Moreover, Samsung has also offered some key sensors such as Galaxy 4’s UV sensor, heart rate sensor and a fingerprint sensor. The company has added the option of fingerprint sensor for the security and ease of users.

As per the reports of Chinese publication, the executive has already stated that the upcoming smart phone will be made of “new materials”. It will have a design similar to Galaxy Alpha. The company is planning to make agreements with some Taiwanese metal supplier for this purpose. Surprisingly, the suppliers which the company chose are famous for their loyalty with Apple. However the news is that these suppliers may increase the material pieces for its non Apple customers.

Storage:

As far as the storage is concerned, the Galaxy Note 4 comes with an internal storage of 32 GB. As always the company has also given the option of  a SD card slot along with a 50 GB  of cloud storage from Drop box. Usually, storage is the chief concern of smart phone buyers because of which Samsung has introduced ample of memory for the storage of games and other  contents. Therefore, assumptions are that Galaxy S6 will offer similar extendable storage.

Software:

As we all are aware that Samsung typically offers the latest Android software, therefore the company released Galaxy Note 4 with Android 4.4.4 Kitkat. In that case Samsung Galaxy S6 should arrive in the market with Android L. Android L is expected to release at the end of this year with some new Nexus hardware.

Improved camera, software and processor:

It is a convention of the company to upgrade three main areas of cell phone every year.  In Galaxy Note altered three things which are a camera of 16 MP, improved snapdragon 805 from Qualcomm in U.S and a brand new S Pen. Hence, there is a possibility that Samsung will upgrade these three things in Galaxy S6 as well.

We would expect Galaxy S6 to come with a new chip of any sort which would perform much better than the Galaxy S5 snapdragon 801 chip. However, it is confirmed that it would not have an S pen like Galaxy Note 4.

 

Carriers:

The Galaxy S came with a variety of carriers in the U.S, which includes the top five pre-paid in it. The Galaxy Note arrived with AT&T, Sprint, T-Mobile, U.S Cellular and Verizon. It is the tradition which the company followed from several years and the same thing we are expecting in the next year with Galaxy S6.  The company will surely struggle hard to compete with iPhone 6 even in the area of carriers.

Focus on Battery Life

Samsung offered a huge battery life in Galaxy Note 4 which comprises Galaxy S 5 Ultra Power Saving  mode  and fast charging ability.  It is evident that the company is concentrating to increase the battery life of Smartphone every year. Hence the expectations are same with Galaxy S6.

 

Galaxy S6 without Gimmicks:

This time Samsung is more focused on the features which people really want to see in the rather than the gimmicky software and hardware features. The Samsung Galaxy Note 4 released with a lots of battery features since people are more worried about the battery than anything. High Resolution camera is the first thing which people ask before the purchase of new cell phone. Although, the design of the Galaxy Note Edge looks similar to a gimmick, but still cannot be considered as the flagship Smart phone. The acceptable alteration which the company made in Galaxy Note 4 indicates few major changes of the Samsung Galaxy S6.

Since Galaxy Note 4 is available in the markets now people are looking forward towards the rumors related  to Galaxy S6.

Two of the most famous start up companies which are biggest rivals are blaming each other. The quarrel of Apple and Google was considered the most fierce in the arena of technology, even that dispute is smaller in front of this bitter accusation.

Though the head offices of Uber technologies Inc. and Lyt Inc. are in the same metropolis, San Fransico but their resentment for each other is now prominent even in other cities. The companies are competing desperately to capture the market of transportation.

The conflict between them was already acute, but recently one claimed that the other one is striving hard to defeat the business.

On Monday Lyft has stated that since October 2013 almost 180  people who work in Uber has ordered and then abandoned. These tacts evidently had a negative impact on the conglomerate because it disturbed their service to a greater extent. Moreover, the company said that it is extremely a disgraceful act of the adversary to apply these techniques in order to slack down the business of Lyft.

Shortly after this accusation, Uber spokesman said that all these claims are untrue and Lyft is merely doing this to damage the reputation of the company. Furthermore, the spokesman said that even Uber has the similar complain with Lyft the driver and employees of Lyft has cancelled almost 13000 trips on Uber. The two companies did not pronounce the sources or evidences of these claims.

The chief purpose of this battle is to achieve the vital role of the future urban transportation. A large number of travelers now prefer Uber and Lyft for moving around rather than hiring a cab or going by bus or train.
