  Kidney  The kidneys are bean-shaped organs that serve several essential regulatory roles in vertebrate animals. They remove excess organic molecules (e.g., glucose) and it is by this action that their best-known function is performed: the removal of waste products of metabolism (e.g., urea, though 90% of this is reabsorbed along the nephron.) They are essential in the urinary system and also servehomeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and regulation of blood pressure(via maintaining salt and water balance). They serve the body as a natural filter of the blood, and remove water soluble wastes, which are diverted to the urinary bladder. In producing urine, the kidneys excrete wastes such…

This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power. The system is described in a paper in the journal Energy and Environmental Science, co-authored by professors Angela M. Belcher and Paula T. Hammond, graduate student Po-Yen Chen, and three others. It is based on a recent development in solar cells that makes use of a compound called perovskite — specifically, organolead halide perovskite — a technology that has rapidly progressed from initial experiments to a point where its efficiency…

Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT. The researchers evaluated an emerging method of power generation called pressure retarded osmosis (PRO), in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less-salty stream would cross the membrane to a pre-pressurized saltier side, creating a flow that can be sent through a turbine to recover power. The…

Lesson 1: Adopt a disciplined approach to investments If there is one thing that Narendra Modi lives by, it is his discipline. Come what may, he is known for never moving away from his disciplined regimen. This is a great thing to learn and emulate from our Prime Minister. As an investor, if you have a systematic and disciplined approach towards investing, your financial goals will seem more achievable. Chalk out an investment plan to meet the financial goals you have in mind and invest accordingly. Lesson 2: Do away with the clutter As soon as Prime Minister Narendra Modi…

Clenergy Wins Bid To Supply Equipment for Pakistan’s Largest Solar Power Project The largest solar power project in Pakistan has started to take shape as orders have been placed for the mounting structures for solar photovoltaic modules. These mounting structures will be supplied by China-based Clenergy International. Clenergy International has joined hands with TBEA SunOasis to supply mounting structures for 40 MW of solar PV modules to the Quaid-e-Azam Solar Park project. The proposed 1,000 MW project will have 100 MW installed by the end of this year while the project is expected to achieve the full capacity by 2016.…

Google executives seem to keep leaving for companies based in China. Last August Hugo Barra left his post at Google as vice president of Android to become VP of cell phone maker Xiaomi Global. In May Baidu snatched up Deep learning guru Andrew Ng, who was leading Google’s Brain project. And last week Alibaba nabbed Jane Penner, who was heading up Google’s Investor Relations department. That’s three employees in a year to leave Google for China’s growing tech sector. So why did these Googlers leave the pack? There was rumor that Barra might have left because Google founder Sergey Brin had taken…

The Japanese Space Agency JAXA actually has a project in the planning stage to beam power collected with solar energy technology in space to earth. The Space Solar Power Systems project ( SSPS project ) is a space-based solar power plant that generates energy by collecting sunlight in geostationary orbit. The energy is then transmitted to the ground, and converted into electricity and hydrogen for practical use. SSPS consists of a space-based power generation/transmission facility that gathers sunlight, converts it into microwaves or laser beams, and transmits those to the ground; and a power receiving facility on the ground. The…
