Can lung cancer be found early?

Lets starts with few introduction.

 Lung Cancer: Cancer of the lung, like all cancers, results from an abnormality in the body's basic unit of life, the cell. Normally, the body maintains a system of checks and balances on cell growth so that cells divide to produce new cells only when new cells are needed. Disruption of this system of checks and balances on cell growth results in an uncontrolled division and proliferation of cells that eventually forms a mass known as a tumor.

Call for 'radical action' on drug-resistant malaria

  

Malaria-infected red blood cells

Drug-resistant malaria is spreading in South East Asia, and has now reached the Cambodia-Thailand border, according to a study.

"Radical action" is needed to prevent further spread of malaria parasites resistant to key drugs, say scientists.

The spread could undermine recent gains in malaria control, they report in the New England Journal of Medicine.

Australia approves $15.5bn coal and rail project

 

critics fear the mine project will have an indirect impact on the Great Barrier Reef

Australia has approved a $15.5bn (£9bn) coal project, despite concern over its potential environmental impact.

The Carmichael project in Queensland would include one of the world's biggest coal mines and a new railway.

It would be overseen by the Indian mining company Adani, which has already won approval to build a new coal port terminal at Abbott Point in Queensland.

But critics have voiced concern over local water use and possible indirect impact on the Great Barrier Reef.

The decision to approve the Carmichael project, which will dig up and transport about 60m tonnes of coal a year for export, mostly to India, was announced on Monday.

Adani is yet to make a final commitment to the project, which would be biggest coal mine ever proposed for Australia.

Environmental impacts

Situated in the Galilee Basin in the central Queensland region, the Carmichael project would include open cut and underground mines.

Coal would be taken from the new mines by rail to Abbott Point coal port north of Bowen.

There are concerns that the mine, which will require some 12 billion litres of water every year, would drain groundwater supplies in the Galilee Basin.

But Australia's Environment Minister Greg Hunt said the approval had been tied to 36 "strict" conditions focused on conserving groundwater.

Separately, environmentalists are also concerned about extensions to the deepwater port at Abbott Point, where Adani already has approval to build a coal export terminal.

In January, Australian authorities approved the dumping of dredged sediment in the Great Barrier Reef marine park as part of an Abbott Point coal port extension project.

The extension will see Abbott Point become one of the world's biggest coal ports.

The decision was made by the Great Barrier Reef Marine Park Authority even though some scientists had urged it not to back the project, saying the sediment could smother or poison coral.

Violence keeps crews from MH17 crash site

An armed pro-Russian separatist is seen at the Malaysia Airlines Flight MH17 crash site near the village of Hrabove, in Ukraine's Donetsk region. 

Kiev - Fighting between Kiev forces and pro-Russian separatists on Tuesday prevented international investigators reaching the MH17 crash site in Ukraine for the third day running, the Dutch justice ministry said.

Liberian Doctor Dies of Ebola

A senior doctor working at Liberia's largest hospital has died of Ebola.

The Liberian Health Ministry says Dr. Samuel Brisbane died Saturday at an Ebola treatment center on the outskirts of the capital, Monrovia.

He is the first Liberian doctor to die in an outbreak the World Health Organization says has killed 129 people in the country.

The U.S. based aid group Samaritan's Purse said Saturday an American doctor working in Liberia is also sick.

A spokeswoman for the group says Dr. Kent Brantly is undergoing intensive medical treatment.  She says patients have a better chance of survival if they receive treatment immediately after being infected, which Brantly did.

The World Health Organization says highly contagious Ebola virus has killed at least 672 people in four African countries this year.

In Sierra Leone, health officials say an Ebola patient whose family sparked a nationwide hunt when they forcefully removed her from a treatment center and took her to a traditional healer, died in an ambulance on the way to a hospital.

Health officials say fear and mistrust of health workers in Sierra Leone, where many people have more faith in traditional medicine, are hurting efforts to contain the Ebola outbreak.  

The WHO says the outbreak, the largest ever recorded, has also killed 319 people in Guinea and 224 in Sierra Leone.

Meanwhile, Nigeria has stepped up surveillance at its ports and borders, following the country's first confirmed death from the Ebola virus.

Health officials are monitoring airports, seaports and land borders for people arriving who may show signs of the virus.  Officials confirmed Friday that a man who died after arriving in Lagos on a flight from Liberia had tested positive for Ebola.

Investigators are trying to track down the other passengers who were on the nearly three-hour flight from Monrovia.

There is no cure or vaccine for Ebola, which causes symptoms that include fever, vomiting, diarrhea and bleeding.

Health workers are at serious risk of contracting the disease, which spreads through contact with bodily fluids.

Six new genetic risk factors for Parkinson’s found

 

Scientists have identified more than two dozen genetic risk factors involved in Parkinson’s disease, including six that had not been previously reported. Unravelling the genetic underpinnings of Parkinson’s is vital to understanding the multiple mechanisms involved in this complex disease, and hopefully, may one day lead to effective therapies,’ said Andrew Singleton, a scientist at the US National Institutes of Health’s National Institute on Aging (NIA) and senior author of the study.
